JZJW series roots-oil-free reciprocating vacuum system comprising a roots vacuum pump as the main pump, and a WLW vertical oil-free reciprocating vacuum pump as the backing pump, the two pumps is parallel connected. These system remain the advantage of large pumping speed, which belongs to ZJP series vacuum pumps, and at the same time avoid the disadvantage of low pumping speed when it comes to high ultimate vacuum, which belongs to WLW series vacuum pumps. Thus JZJW series system is widely used in the processes of vacuum distillation, vacuum evaporation and vacuum dehydration & crystallization for chemical industry;freeze-drying for food industry; vacuum drying for pharmaceutical etc.
JZJW series are fit to be used to collect gases like pentadiene,benzene, methylbenzene etc,which are anti-compressed,anti-concretion in high vacuum system. All this due to that the WLW series vacuum pumps adopted the oil-free and self-lubricating materials, then it can obtain spotless vacuum.
JZJW series system are the new production developed by company and National Scientific and Reach Unit. As the ideal production to protect environment,energy-saving,small occupying of area, water-saving, low noise is the system’s main characters.
1. High ultimate vacuum, long range of vacuum
2. Large pumping speed under higher vacuum
3.Lower shaft power, small consumption
4. Without second-time water pollution, the pollution is limited in small area
Each JZJ2B series roots-liquid ring vacuum system comprising a ZJP series roots vacuum pump as main pump, a SKA(2BV/2BE1) series liquid ring vacuum pump as backing pump and other valve&measure apparatus with pips to consist the unit. The units are applied to exhausting normal gases and gases with water, organic solvents or a little dust. Compared with normal mechanical vacuum pumps, the units resist oil, steam and dust. Compared with normal water ring vacuum pumps, they have high vacuums and high exhaust speeds under high vacuum, which make the unit more fit for drying dehydration and vacuum degassing in textile, food, chemical and industry fields. Comparing with common liquid ring vacuum pump,the capacity to remain high pumping speed under high or ultimate vacuum degree becomes its main advantage. Except for normal gas suction, this system can also pump special gas with small amount of vapor or dust. Additionally, this system is free from oil pollution, as well as vapor and dust. Since the 2BV type of liquid ring pump has been adopted as its fore pump, the JZJ2B series system is more efficient than JZJ2S series (which 2SK type of liquid ring pump has been adopted). And it is compact-designed with no air leakage and high protection level. Besides,our 2BV type is more anti corrosive than 2SK type, because all 2BV impeller are albronze material. Another note, the fore pump can be designed as a closed circulation system so to reduce the environment pollution greatly. JZJ2B series system has become an ideal choice for vacuum drying or dehydration process, and vacuum degassing process in the field of light textile, food industry, chemistry, pharmacy, etc.

Pump Unit A beam and crank assembly creates reciprocating motion in a sucker-rod string that connects to the downhole pump assembly. The pump contains a plunger and valve assembly to convert the reciprocating motion to vertical fluid movement. As the beam pumping system rocks back and forth, this operates the rod string, sucker rod and sucker rod pump, which works similarly to pistons inside a cylinder. The sucker rod pump lifts the oil from the reservoir through the well to the surface. A beam pump is an artificial-lift pumping system which uses a type of reciprocating pump to extract oil from an inland well. Nodding donkeys or beam pumps are a common artificial lift system used in land-based operations. A pumpjack is the overground drive for a reciprocating piston pump in an oil well. It is used to mechanically lift liquid out of the well if not enough bottom hole pressure exists for the liquid to flow all the way to the surface. The arrangement is commonly used for onshore wells producing little oil. Because of their characteristic shape and motion, pumpjacks, also called beam pumps, are often given fanciful names such as "lonely birds" and "nodding donkeys." Whatever name you call them, such pumps are critical to crude oil production.
1.Overview Stainless steel welded pipe is superior to stainless steel seamless pipe in terms of material and mechanical properties, but the weld reinforcement of stainless steel welded pipe, especially the inside weld reinforcement control has always been a difficulty to be overcome by welding pipe industry. Though many manufactures tried inner blade or inner grinding device solution, the effect is not satisfied. This is the main impediment to further expend wider application in the welded pipe industry. Thus, in petroleum, chemical, nuclear power, boiler, food, pharmaceutical and other industries, stainless steel seamless pipe is still the mainly choice. 2. Our Equipment The welding seam inside Leveling machines is composed of leveling frame, hydraulic and pneumatic systems, PLC fully automatic controlled electro-hydraulic pneumatic system, also including molds and rolling fluid circulation device. 3. Technical features The principle of welding seam inside leveling machine is employing a built-in mandrel and roller, reciprocating rolling the stainless steel welded pipe automatically, by controlling the rolling strength and pass to level both inner and outer side of the welding seam , completely control the weld reinforcement to be flushed with the base material. Generally speaking, the technology is to achieve the seamless stainless steel welded pipe effect.
