Hydraulic Manifold Blocks

For the Hydraulic Manifold Block with porous system like cranial nerve, after made samples successfully, They have a special hydraulic manifold block, which includes 13 groups of M32 threaded holes, and all of them are stepped holes. At the same time, there are cross holes, straight holes, and bypass holes. The hole size is required to be more than 8. Compared with the hydraulic manifold blocks with 10 groups of normal threaded straight holes, it is not only complex in structure, but also 20% higher in precision. Arno knew that it was difficult, so he arranged 3 hydraulic manifold block manufacturers for proofing, which lasted 60 days, but all of them failed to meet the standard. This is a test order of hydraulic manifold block from an old customer. Arno wants to struggle again. Due to time constraints, he does not dare to use a new hydraulic manifold block manufacturer. His old hydraulic manifold block supplier is also unreliable. This makes , who has eight years of procurement experience, a little overwhelmed. I had a hunch that this hydraulic manifold block was not simple. Because the PO of hydraulic manifold blocks given to me by is a challenge every time. engineers pondered over the drawing of hydraulic manifold block sent by , and it is really difficult to process, with very high precision. There are not only many pore systems, but also many deep holes, more than 20 groups of 4 deep holes, with a length diameter ratio greater than 25. For M32 threaded holes of stepped holes, the coaxiality between holes is required to be 0.02mm, and the coaxiality between threads and holes is required to be 0.045mm. This complex pore system structure is like the distribution of the nervous system of the human brain. Doctors without more than 10 years of experience in brain surgery may not be confident to operate on the operating table. technical team, after 3 days of internal research and discussion, the plan has been worked out, and our chief engineer will handle the knife, starting from the production drawing of the hydraulic manifold block. However, I replied to that was only 90% sure that the sample of this hydraulic manifold block was successful, and the cost was not low. Maybe hesitated and didn't give any reply for 3 days. On the fifth day, received the development fee paid by him.

This morning, Joselito sent an email asking about the production time of 1,000 hydraulic manifold blocks, which surprised me a little, because in the past two years, Joselito has basically placed orders for just hydraulic valves only, but very few for the hydraulic manifold blocks. Joselito is a purchaser of BEZARES company in Spain. We met 2 years ago. After communication, it was learned that he encountered problem on the hydraulic manifold blocks purchased this time. A batch of hydraulic winch equipment of their company was complained by some users that the winch was often weak. Their after sales found that the hydraulic manifold block was leaking. Because of the purchase cost limitation, he disassembled the hydraulic manifold blocks and purchased them separately from 3 hydraulic valve manufacturers. Now the leakage problem of the hydraulic manifold blocks has come, all 3 manufactures prevaricate and are not responsible for the oil leakage of the hydraulic manifold blocks, they thought that the problem was caused by the unreasonable design or the wrong installation method of the hydraulic manifold blocks. The engineer checked the hydraulic manifold blocks one by one and found different problems, some sealing ring was broken, some gasket at the interface was worn, and some has iron filings in the valve hole. In the past year, a lot of money, labor and maintenance costs were spent on the after-sales for the hydraulic manifold blocks. Now the customers are not satisfied with their after-sales performance, and the boss is not happy to spend the after-sales money indiscriminately. Joselito has a big headache. AAK suggests that Joselito should purchase the whole hydraulic manifold blocks in one factory as much as possible, because each hydraulic valve manufacturer has different quality positioning. AAK has now received more and more inquiries for hydraulic manifold blocks, including Skyjack, a Canadian listed company, and Brevini, a top company in the field of transmission. Joselito finalized the purchase contract of the hydraulic manifold blocks with AAK in two rounds, and required that AAK hydraulic manifold blocks should not be reported for repair within 1 year. It is not only the hydraulic valves and hydraulic manifold blocks produced by AAK with quality assurance, but also 3 points that are difficult for peers to do well: 1. AAK shall deeply clean the hydraulic manifold blocks before assembly to ensure that it is 100% free of iron filings, dirt and other impurities. 2. Only technicians with more than 10 years of experience are qualified to assemble, check the matching between the duct and the hydraulic schematic diagram, and test the accuracy of each duct to ensure that the sealing ring of the hydraulic valves will not be damaged. After assembly, use the test bench to debug the hydraulic manifold blocks for many times, including pressure test and function test,

With hydraulic manifolds, the energy consumption of the original unsalable equipment not only decreased by 20%, but also became hot seller is from a agricultural machinery equipment company, mainly responsible for purchasing hydraulic components. In the second half of last year, the sales of one of their rotary tillers were poor. Users reported that the equipment was insensitive and inefficient, and the fuel consumption was 10% higher than that of the same type of equipment. The boss realized that there were hidden dangers in the hydraulic manifolds and asked the engineers to check the causes. However, more than 1 month had passed and there was no practicable plan. The boss was worried and asked to contact the original hydraulic manifold manufacturer to see if they could provide technical support, but they were only good at producing hydraulic manifolds according to the drawings. Connor also asked all his manufacturers of hydraulic components, but none of them gave a plan. When reported these to his boss, he could only helplessly look at his boss shaking his head. the display and introduction of hydraulic manifolds, and left a message: what is the relationship between hydraulic equipment with high energy consumption and slow response and hydraulic manifolds I understood that Connor had a problem with hydraulic manifolds, but it was difficult to answer. After several communications, I learned that his boss was worried, and wanted to solve the problem that had plagued his company for nearly 3 months. According to the hydraulic manifold drawings and the video of rotary tiller work sent by engineers had discussion. The probability was that the hydraulic manifold design had hidden problems. From the analysis of hydraulic manifold and system schematic diagram, there were certain energy conflicts between the design of some oil circuits and the selection of hydraulic valves. could redesign the hydraulic manifold to match their equipment. also readily paid the development cost. 1 month later, sent the hydraulic manifold samples. 2 months later, said that after their rotary tiller was installed with hydraulic manifolds, it was responsive during operation. The operation was more than 20% higher than before, and the fuel consumption was also reduced by 20%. The customer feedback was good, and more and more customers came to try it out. told me privately that he had seen his boss's long lost smile. The boss paid more and more attention to him. He will be promoted to the management next month. hydraulic manifold has 3 advantages 1. engineers have experience in hydraulic manifold design, especially in oil circuit design. Ensure flow distribution as required, eliminate bypass throttling loss and reduce energy loss.

Increase the equipment efficiency by 11% and reduce the energy consumption by 30%. AAK exclusive hydraulic manifold has no rival At the beginning of March this year, Bartolomeo said in an email that he would like to make an appointment to consult AAK about hydraulic manifold problems. Bartolomeo, from Italy, is the purchasing manager of Italpresse Industrie Shanghai Branch. According to the communication, their company developed a hydraulic die-casting machine at the end of last year. The sales volume is just so. The general feedback is that the equipment has high energy consumption and low production efficiency. Their engineers pondered for more than 2 months, but couldn't find the reason, and the boss also had a big headache. Bartolomeo felt that the hydraulic manifold design dragged down the equipment and consulted the original hydraulic manifold manufacturer. However, the manufacturer could not put forward constructive opinions on the hydraulic manifold design. Bartolomeo thought of AAK, because AAK had proposed to modify the oil circuit when receiving the inquiry about the hydraulic manifold. According to the design drawings and system schematic diagram of hydraulic manifold provided by Bartolomeo, AAK engineers closed the door and discussed for 3 days, basically found out the direction, and it is 90% determined that there was a deviation in the oil circuit design of the original hydraulic manifold on the hydraulic die casting machine. There is an energy conflict between the original hydraulic manifold oil circuit aperture and the hydraulic valve used, resulting in the slow response of the hydraulic system and the need for additional energy to maintain the operation of the system, resulting in high energy consumption and low production efficiency. AAK can redesign the hydraulic manifold oil circuit and send hydraulic manifold samples within 30 days. Bartolomeo was very happy that AAK found the cause of hydraulic manifold problem at once. The situation was fed back to the boss, who immediately paid for AAK to redesign and test samples. A month later, AAK sent out the whole newly designed hydraulic manifold. Two weeks later, Bartolomeo emailed to order 20 hydraulic manifolds first to replace those ones on the equipment complained by customers. I was surprised that there was no comment on AAK hydraulic manifold samples but received the urgent order first. Bartolomeo advised that according to the comparison of their engineerâ??s on-site test run, the die casting machine with AAK hydraulic manifold has a sensitive response, the working efficiency is 11% higher than before, whatâ??s more, the energy consumption is reduced by 30%. Their boss asked to order some hydraulic manifolds for emergency use first, and then replace all hydraulic manifolds on the original equipment with AAK shipments.

The hydraulic valve blocks designed and produced by not only has high reliability and small pressure loss to ensure that there is no oil running between the channels, but also has compact structure, small occupied space, simple oil circuit and easy pipe layout, so as to ensure the high efficiency requirements of different actions of various actuator elements. The valve block can control the valve, which is easy to adjust and operate. hydraulic valve block was designed and proofed successfully at one time within 1 month, which impressed the engineers o The vast majority of hydraulic valve block manufacturers blindly proofed according to customer drawings, ignored working conditions, and did not understand the internal structure and working principle of hydraulic valve block. It is easy to cause hidden dangers in the hydraulic system, and the problem cannot be found. power insensitivity of the hydraulic system related to the hydraulic valve block We replied that this is difficult to judge because it is a system problem that needs to be checked one by one. the next day then we understood why he left such The power unit of a hydraulic system developed by his company needs a hydraulic valve block. Their engineers mentioned that the sensitivity of the power unit is the key and that all components need to cooperate closely. the hydraulic valve block manufacturer strictly controlled the accuracy according to the drawings, it could be easily done. After the hydraulic valve block is finished, it is installed to test the hydraulic power unit. After the oil pump is started, the instantaneous pressure supply at the oil outlet of the power unit does not come up, and it just supply normal pressure after a few minutes. After checking each component one by one, it is suspected that there are hidden dangers in the hydraulic valve block. After detecting the hydraulic valve block, there is no problem in the oil passage and channel of the hydraulic valve block the original hydraulic valve block manufacturer for analysis and solution. The manufacturer said that the hydraulic valve block was completely produced in accordance with the drawings and the accuracy was within the required range, and the reason for problem was unknown. hydraulic valve block , they all said that they could match the drawings, but not sure about the problems of the hydraulic valve blocks. hydraulic system and the picture of the oil circuit running direction of the hydraulic valve blocks of the original have ideas after 3 aspects of comparative analysis.

AAK's 3 tips to ensure that the Proportional Valve is free of jamming, winning the affirmation of customers in Turkey Ewalz is from Turkey, and mainly purchases standard parts of hydraulic cartridge valves from Ningbo China. Recently, they developed a hydraulic manifold that requires the use of SUN proportional valves. He purchased it from a proportional valve manufacturer in Ningbo, and after 2 weeks of operation, the equipment experienced significant vibration. The on-site engineer found that the proportional valve was severely stuck. The original hydraulic valve manufacturer stated that this proportional valve is a replica of SUN, with fully calibrated parameters, but there are differences in performance. Ewalz was speechless and had to look for a new hydraulic valve manufacturer for this proportional valve. Ewalz browsed the AAK hydraulic valve website, stayed for nearly 15 minutes and left a message: 1. Does AAK have an existing program for benchmarking SUN proportional valves? 2. Can AAK completely solve the problem of valve spool jamming, vibration and noise? After communication, it was learned that the hydraulic manifold they developed was very tight on time, they had no time to customize it and could only choose the existing SUN proportional valve. The proportional valve produced by the original valve manufacturer has the same function as SUN, but has poor performance. This SUN proportional valve is widely used, and AAK have a record of 6 shipments last year. There has never been any jamming of the valve spool, and we have inventory, which fully meets his requirements. 2 weeks after AAK sent the SUN proportional valve samples, Ewalz informed us via email that the hydraulic manifold debugging was successful. 2 months later, Ewalz informed us that their engineers were satisfied with the AAK proportional valve. The root cause of unsatisfactory performance of the original valve manufacturer's SUN proportional valve lies in its accuracy. The vast majority of proportional valve manufacturers have a cylindricity machining accuracy greater than 5um, which is 70% lower than the SUN standard cylindricity. For the accuracy of proportional valves that is completely in line with the SUN standard parts, there are probably less than 3 hydraulic valve manufacturers in Ningbo China. AAK controls the accuracy of the proportional valve from 3 aspects: 1. AAK proportional valve spool control: The valve spool is produced using a German CNC lathe with one blade and then high-precision cylindrical grinding. The machining error is controlled within �± 1um, and the coaxiality and cylindricity are controlled within 3um. 2. AAK proportional valve hole control: Adopting Swiss honing processing, the accuracy can reach IT6-IT7 level, and the surface roughness can reach Ra0.2-0.025um.

hydraulic relief valves . purchased a batch of hydraulic relief valves for crane system in because the original supplier was not able to meet the delivery. He sent an email last week saying with hydraulic relief valves, the stability is 8% higher than that of the original supplier, and there is almost no external leakage. This surprised him. The use experience of hydraulic relief valves has benchmarked with their previous local hydraulic relief valve manufacturers The vast majority of hydraulic valve bodies are made of nodular iron, vermicular iron and gray iron and cast with resin sand as the molding medium. Therefore, there is sticky sand in the casting, which is easy to pollute the oil system and block the valve and filter, which is the key factor affecting the stability of hydraulic relief valves. Most of the common sand cleaning methods of hydraulic relief valves used in the industry are shot blasting and electrochemical sand cleaning, all of which have limitations. 1. Shot blasting can not completely remove the sticking sand from the valve hole with complex structure and small oil passage, which is easy to affect the tightness and product accuracy, and is not conducive to the stability of the hydraulic relief valves. 2. Electrochemical sand cleaning can relatively remove the sticky sand in the narrow oil passage, but it has high energy consumption, high operation intensity of workers, easy to have human errors, can not completely remove the sticky sand, and is not conducive to the stability of the hydraulic relief valves. Improving the quality of hydraulic parts processing process, improving the cleanliness level and ensuring the stability of hydraulic relief valves has always been the hard index of hydraulic relief valves. Auxiliary processing of hydraulic parts mainly includes: sand cleaning of valve body, deburring or residue treatment of parts and cleaning of hydraulic parts. How does do the sand cleaning of hydraulic relief valves technical team has continuously improved the sand cleaning process of hydraulic relief valves after years of technical improvement. For the sand cleaning of small complex castings, has its own unique sand cleaning 5 methods, namely: artificial aging - Pickling - rinsing - rust prevention - ultrasonic cleaning. Artificial aging is used to reduce the binding force between the casting and sand, acid pickling is used to remove the oxide skin at the joint between the sand and the casting to peel the sand from the casting, and then the explosion of compressed air during ultrasonic cleaning is used to peel off the sand, so as to achieve the purpose of sand cleaning. has its own unique advantages of sand cleaning 5 methods: (1) it is less affected by the casting structure; (2) it is

Recently, the PO quantity of hydraulic pressure regulating valves has suddenly increased. Whether it is the trial order or the daily order of wholesale customers, after the delivery date of the hydraulic pressure regulating valves is determined, the customers begin to pay. Brooke is my old customer. We have cooperated for more than 1 year. Most of his orders are hydraulic pressure regulating valves. Yesterday, Brooke placed a new test order and advanced the full amount. I asked him why he chose to give it to Brooke replied to us as follows: 1. gives as much as it promises, unlike other hydraulic valve manufacturers who over promise but can't fulfill the commitment. 2. In the technology of hydraulic pressure regulating valves, I trust most. 3. In terms of service details, is the best in my current hydraulic valve supply system. My first business with Brooke was also the hydraulic pressure regulating valve. The first PO was a small order for the hydraulic pressure regulating valve. The second time, there was an inquiry for a large number of hydraulic pressure regulating valves, and we also made samples, but Brooke told me that because the price of was 17% higher than that of another hydraulic pressure regulating valve manufacturer in , so he purchased it from another factory. I remember that I joked: if there is no problem with the hydraulic pressure regulating valves you purchased, I will admire you. At that time, he needed a hydraulic pressure regulating valve with high pressure parameters. There may not be a third hydraulic pressure regulating valve manufacturer in Ningbo who can meet this parameter. As expected, Brooke said in an email last month that he was trapped by another manufacturer of hydraulic pressure regulating valves in . After the goods arrived, the workshop technicians installed the hydraulic pressure regulating valves and began to increase 20% of the rated pressure for pressure test. After 24H, some hydraulic pressure regulating valves leaked. However, in the approval stage, the samples of hydraulic pressure regulating valves from this factory were up to standard. Brooke contacted the manufacturer of the hydraulic pressure regulating valves, but manufacturer replied that there was no stock to replace them. Brooke replaced the hydraulic pressure regulating valves with samples from originally, and there was no leakage problem under the same working conditions. Finally, adjusted the production schedule specially and produced new goods for him, which completely solved the leakage problem of the hydraulic pressure regulating valves. I told Brooke that to meet the requirements of this high-pressure working condition, special attention needs to be paid on not only the material selection, but also the material heat treatment and workpiece processing accuracy. More importantly, each hydraulic pressure regulating valve should p
