Down-hole motor

Product Description

Down-hole motor is a positive-displacement motor，after the high-pressure fluid drilled into the motor , it makes the hydraulic energy converted into mechanical energy , and the motor drives the principal shaft and bit rotating to drill to achieve the purpose of drilling. We can manufacture the specifications with LZ*3, LZ*9, LZ*5, LZ**2, LZ**0, LZ**5, LZ**2, LZ**7, LZ**3, LZ**6, LZ**4, for the range of drilling diameter through *8.9 to **4.5, and we can also design special size, diverse configuration and working specialty according to the needs of customer. In addition to the common straight down-hole motor, we can also manufacture the following specifications: 1. Bended Down-hole motor: The bent angle on the universal axis can fit the needs of different curvature of kicking off. Divided into single and double bent 2. Bent angle adjustable down-hole motor: To improve the bending slope of the screw hole on the different requirements, the bent angle of the downhole motor can be adjusted on well surface, which enhances the extension of the kicking off. 3. Extended down-hole motor: On the basis of the common down-hole motor, the torque can be increased with the step increasing for the motor to achieve the purpose of breaking rock fast. 4. Hollow rotor down-hole motor: The adoption hollow rotor for different sizes of hard alloy jet nozzle increase the ting flux and water drive of drill bit. 5. High kick-off down-hole motor: The curvature of kicking-off can achieve over 1° per meter with the particular design, the shortness length of the whole and adjacent bend to the bit. 6. Saturated saltwater mud resistant down-hole motor: The special coating layer of rotor has stronger ability of corrosion and wear resistance, enabling the down-hole motor to work for a long time in saturated saltwater mud. 7. High temperature down-hole motor: The resistant temperature of motor can achieve over **0℃ by the using of excellent resistant temperature rubber in the stator. With the ability of the resistant temperature rubber improving, the requirement of the deep-well, up deep-well and High temperature gradient region drilling can be satisfied. 8. Sealed transmission shaft down-hole motor: By converting the mud sealed to the oil sealed of transmission shaft, we improve the condition of thrust axletree and radial axletree, which extends the life of the down-hole motor.
