The reason why hydraulic steering gear cannot rotate

The oil pump drive belt is loose or the liquid level in the oil tank is insufficient, resulting in insufficient oil pressure and affecting the normal operation of the steering gear.

There is air or moisture inside the steering booster, or the meshing degree of the steering gear is not appropriate (too loose or too tight), which hinders the smooth rotation of the steering gear.

Loose nuts on the thrust bearing of the steering screw or internal faults in the oil pump can interfere with the normal function of the hydraulic steering gear.

The oil pump bypass valve is stuck, the oil pump safety valve seat is detached, the manifold is deformed or the gasket is damaged, which affects the rotation of the hydraulic steering gear.

Hydraulic pump wheel wear, internal failure of hydraulic turbine or hydraulic coupling, causing the steering gear to not rotate.

The internal overheating of the hydraulic steering gear leads to an increase in oil viscosity and a decrease in hydraulic transmission efficiency.

The oil circuit is blocked due to the accumulation of oil stains or poor hydraulic oil quality in the oil circuit.

Component wear, especially gear wear, leads to increased clearance between gears, even jamming or non rotation.

Loose or severely worn joints can affect the overall stability of the machine's operation.

The control harness of the steering wheel has fallen off, or the fuse of the steering wheel has burned out, causing the steering wheel to be unable to rotate.
