One of the common faults of Hydraulic Pumps is insufficient output flow. Possible reasons include wear of internal parts of the pump, such as the increase in the gap between the plunger and the cylinder body, the distribution plate, etc. At this time, the pump body needs to be disassembled, and the severely worn parts need to be checked and replaced. There may also be leakage or blockage in the oil inlet pipeline. Check whether the pipeline connection is tight and clear the blockage.
Insufficient pressure is also a common problem. The reason may be that the set pressure of the safety valve is too low. The safety valve pressure can be appropriately increased, but be careful not to exceed the rated pressure of the pump. In addition, inappropriate viscosity of the hydraulic oil will also lead to insufficient pressure. It is necessary to replace the hydraulic oil with a suitable viscosity according to the requirements of the pump.
Abnormal heating of the pump body is usually due to excessive mechanical friction or poor heat dissipation of the hydraulic oil. Check whether the bearings and other parts of the pump are damaged and replace them in time; at the same time, ensure that the oil tank cooling device is working properly, and increase the heat dissipation area if necessary.
Excessive noise may be caused by the inhalation of air in the pump. Check the seal of the oil inlet pipeline and remove the air; it may also be caused by damage to the internal parts of the pump. Impact, in this case, requires disassembly and repair or replacement of damaged parts.
