Luhai drilling motor is a positive displacement motor. High pressure drilling fluid flows into the drilling motors, thereby enabling the hydraulic energy to be converted into mechanical energy, at the same time, the rotor drives the shaft and bit to rotate to achieve the purpose of drilling.
Luhai produces LZ73, LZ89, LZ95, LZ102, LZ120, LZ127, LZ146, LZ165, LZ172, LZ185, LZ197, LZ203, LZ216, LZ244, LZ286 and other types of drilling motors. They are for drilling diameter of 88.9-660mm. Luhai also design and develop drilling motors with special sizes, different structural features and operating characteristics in accordance with the user's requirements, thus forming different varieties. At present, in addition to ordinary straight drilling motors, Luhai can also provide the following types of drilling motors:
Bent drilling motors: The bent angle on the universal shaft can meet different kickoff requirement, there are single-bent and double-bent available.
Bent angle adjustable drilling motors:The bent angle of the drilling motors can be adjusted on well surface which enhance the extension of kicking off.
Extension drilling motors: On the basis of the ordinary drilling motor, improve motor torque to make the bit drilling quickly by increasing motor stage.
Hollow drilling motors: To meet the needs of high flow rate solids carrying in drilling, hollow rotors with carbide nozzles of different sizes are adopted, which can increase the input flow rate and the horsepower of drill bit..
Drilling motors with high kick-off rate: Unique structural design, shorter body, bent point closer to the drill bit, and kick-off rate of up to >1°/m.
Saturated saltwater mud-resistant drilling motors: To maintain long time operation of drilling motors in saturated saltwater mud, special rotor coating is adopted to provide better corrosion and wear resistance.
High-temperature drilling motors: In order to improve the high temperature resistance of the stator rubber of the drilling motors, to meet the drilling requirements in high geothermal gradient region and deep and ultra-deep well drilling requirements, high-temperature resistant rubber is adopted to increase the temperature resistance of motor above 150 ?.
Sealed driving shaft drilling motors: The ordinary mud lubricated driving shaft is replaced with oil lubricated seal driving shaft, which improves the working conditions of the thrust and radial bearings, thus extending the service life of the drilling motors.
Mechanical Service
In order to reach the customer's requirements, we have expanded our Machining Services. We now specialize in other services such as Deep Hole Drilling, Precision Grinding, and Welding. Each time we came upon a part which required an outside Machine Shop service, we asked ourselves if we could do that service in workshop.
Step by step we added a broad range of different capabilities.
The first service that we added was Welding. Customer demand required that we not only just machine, but also that we fabricate. We now employ welders that specialize in TIG, and MIG welding.
A bit later we decided to add a Gundrill machine to compliment our growing Honing Department. We are able to drill from 1/8 inch to 20 inches diameter, in all types of materials. Most of the time we will drill a hole on our GunDrill, and then we can Hone it to a precise tolerance and a mirror finish.
Recently we have added a couple of machines to expand our Grinding capabilities.
Features
1. Safe, reliable, and time saving.
2. Simple installation & operation.
3. Choice of drill bits for different ground conditions.
4. Grouting works synchronize with drilling or after drilling. Grout can fill fractures effectively.
5. Anchor bars can be cut and lengthened on request, applying to narrow spaces.
6. It provides higher bonding stress than smooth steel pipe depending on continuous wave thread.
Application
Tunneling
Mining
Slope stabilization
Foundation support
