When choosing a hydraulic drilling motor, the following factors need to be considered:

Power requirements: Select the appropriate motor power according to the model, specifications and operation requirements of the hydraulic drilling machine. Too much power will cause energy waste, and too little power will not meet the operating needs.

Speed matching: The speed of the motor should match the speed of the hydraulic pump to ensure the normal operation of the hydraulic system.

Reliability: The motor should have good reliability and be able to operate stably for a long time in a harsh working environment.

Maintenance cost: Choose a motor model that is easy to maintain and has sufficient accessories to reduce maintenance costs.
