Product type:Oil Drilling Equipments and Parts--Mud Motor
 
Name:COMPONENTS DRILL MOTOR
Item:ydaer_1
Description:
     Down-hole drill motor is a kind of down-hole drill tool driven by mud. As mud fluid from the mud pump enters the motor via the by-pass valve, a certain pressure difference is formed at the inlet and outlet of the motor, pushing the rotor to rotate. Torque and rotate speed are transferred via the universal shaft and the transmission shaft to the bit the performance of the down-hole drill motor is mainly depending on the performance parameters of the screw motor.
 
         COMPONENTS OF DOWN-HOLE DRILL MOTOR
Down-hole drill motor is mainly composed of five assemblies, which include by-pass valve assembly, falling-proof assembly, motor assembly, universal shaft assembly and transmission shaft assembly.
 
i.e.: 5LZ1657.0
It means that the down-hole drill motor with the proportion of the number of rotor and the number of stator of 5:6, OD of 165mm and the nozzle pressure drop of drill bit of 7.0 Mpa.
