Why Water Well Drilling Rig Power Heads Fail

The pressure of the hydraulic fluid is not up to the requirement

The parts of the reducer, motor or gearbox of the power head are faulty, etc.

Secondly, abnormal positive rotation is also one of the malfunctions. Mainly, there is a big noise at no load, but it is normal at reverse rotation. To analyze this, it may be because the gear reducer gear lubricant is insufficient, resulting in dry friction of gears in operation, and then noise; may also be bearing damage caused by abnormal noise; gear wear can also cause abnormal noise in forward rotation; bearing or meshing surface inside the large and hard particles caused by the abnormality of the material.

Finally, the high temperature of hydraulic oil will affect its viscosity, which in turn affects the operation of the power head and easily causes rig failure. Meanwhile, deterioration of hydraulic oil is one of the causes of power head failure.
