How long is the life of a hydraulic pump?
No matter what brand of hydraulic pump, in use after a period of time will appear because of various reasons of life shortened, which we cannot control, but we can improve the environment of hydraulic pump and maintenance methods, increase the service life.
There are many factors affecting the service life of VICKERS hydraulic pump, in addition to the pump itself design and manufacturing factors, and some related to the use of pumps and the selection of related operations in the operation process is also related.
Hydraulic pump is to change the volume of pump chamber by movement, so as to compress the fluid and make the fluid have pressure energy. The change of sealing volume in pump chamber is the necessary condition for the completion of the task.
From the use and maintenance point of view, we should pay attention to the following problems:
1. when the system does not work, the oil pump must be uninstalled;
2. always keep the correct oil level in the tank so that the oil has enough circulating cooling oil;
3. correct selection of viscosity of oil;
4. always keep enough water in the cooler and smooth the pipeline.
Prevent oil temperature too high
For many reasons the temperature varied, such as the volume of the tank is too small, the radiating area is not enough, the amount of oil storage tank is too small, the environment temperature is higher, cooler malfunction; no unloading circuit system, to stop working when the pump is still in high pressure overflow; tubing are too small and too long, bending over, the pressure loss is too large, component processing accuracy is not high, the relative motion of friction heating too much.
Engineering machinery hydraulic system oil temperature is generally about 30 degrees to 80 degrees in the range of good, high temperature to produce a series of adverse effects on the system, such as the decrease of viscosity, leakage increases, volumetric efficiency decreased, resulting in hydraulic speed instability, will cause thermal expansion between the different amplitude space changes, even the death card, will cause the oil deterioration, seals aging, loss of seal etc..
