Hydraulic press manufacturer Hydraulic pump refers to the oil pump in the single-arm hydraulic press system, which provides power to the entire hydraulic system; it is the power element of the hydraulic press system, and its function is to convert the mechanical energy of the prime mover into the pressure energy of the liquid.

1) The pump filter is blocked by dirt and cannot filter the oil; use clean cleaning oil to remove the dirt from the filter.

2) The driving shaft of the pump is not concentric with the motor coupling, and there is twisting friction: adjust the concentricity of the oil pump and the motor coupling so that the error does not exceed 0.2mm.

3) The meshing accuracy of the pump gear is not enough: grind the gear to achieve the gear meshing accuracy.

4) The oil seal skeleton of the pump shaft falls off and the pump body is not sealed: replace the qualified pump shaft oil seal.

5) The oil level is insufficient, the oil suction scale position is too high, and the oil suction pipe is exposed to the oil surface: add oil to the oil mark position and lower the oil suction position.

6) There is no paper pad on both sides of the pump body and the pump cover; the pump body and the pump cover are not vertically sealed; air is sucked in during rotation; paper pads are added between the pump body and the pump cover; the pump body is ground on a flat plate with diamond abrasive so that the verticality error between the pump body and the pump cover does not exceed 0.005mm, and the connection between the pump body and the pump cover is tightened to prevent leakage
