Down-hole Motor:
Working Principles
The downhole drilling motor is a kind of positive displacement motor (PDM). High pressure drilling fluid goes into the PDM drill through drilling rod, and the rotor rotates under the action of hydraulic pressure. The torque is thus transferred to the drill bit.
StructureThe downhole drilling motor is composed of bypass-valve assembly, motor assembly, cardan shaft assembly, transmission shaft assembly and guiding assembly
AccessoriesDirectional sub, bent sub, cardan shell, flexible shell, replaceable stabilizer and shell anti-dropping device
Features1. The downhole drilling motor is designed with adjustable shell to accommodate for 19 slopes ranging from 0 degree to 4 degrees.2. The heat-resistant motor can normally work under high temperature over 180°.3. The motor is coated with corrosion-resistant tungsten carbide to so as to suit saturated saltwater mud application.
