The reason why the pump makes a lot of noise during off-road forklift operation

Jan 8th,2025 160 Views

Why is the working noise of the off-road forklift pump so loud? Why is the rise of the off-road forklift bow normal, but the tilt and rotation are slow and weak? It should be noted that the dual-function valve of some off-road forklifts is located in the tilt hydraulic cylinder. If the tilt is poor at this time, the tilt hydraulic cylinder should be disassembled and inspected.

The normal rise of the off-road forklift mast indicates that the working pressure of the hydraulic system is normal. The main reason is the oil control circuit provided by the tilt hydraulic cylinder.

Why is the off-road forklift pump noisy?

(1) The suction pipe or oil filter is blocked, which blocks the system from entering the fluid. Replace the degreasing hose or clean the filter or replace the filter element.

(2) The suction pipe is not sealed tightly, so that air enters the system. The suction pipe should be repaired.

(3) If the baffle is damaged during the drilling process, the working pump should be replaced.

(4) The gear oil viscosity is too high. The gear oil of a suitable brand should be replaced.

(5) The pump shaft and the rotating shaft are not concentric. Check whether the rotating shaft bearing is burned out and replace it if necessary.
