There are four external factors that can cause pump failure
1) If the hydraulic oil viscosity of the mechanical servo hydraulic press is too high, it will increase the oil absorption resistance, easy to cause cavitation, so that the pressure and flow rate is insufficient; Oil viscosity is too low, which can increase leakage, reduce volumetric efficiency, and easily inhale air. Cause to vibrate or crawl.
2) The environment is not clean, do not pay attention to civilized production, so that iron filings, impurities and dust mixed into the oil. Lighter will affect the normal operation of the system, heavier will affect the life of the pump.
3) The installation of the pump pump shaft and the connection between the driving motor shaft should have good coaxiality. If the coaxiality is too poor, it may cause irregular noise and erratic motion. In severe cases, it can damage parts. Hydraulic pumps have steering requirements, if steering error, not only pump
Oil cannot be transferred to the outside and can quickly damage parts. If the pump speed is selected improperly, it will affect the performance of the pump. If the suction pipe and drain pipe joint is not tightly sealed, it will enter the air.
4) The tank capacity of mechanical servo hydraulic press is small and the heat dissipation condition is poor, which will lead to high oil temperature and often bring many problems; The tank is too large and the oil level is too low, which may prevent the hydraulic pump from drawing in the oil. The height of the suction port of the hydraulic pump is not appropriate, the diameter of the suction pipe is too fine, and the oil cross section of the filter is too small, which will affect the suction resistance. Impurities do not settle well in the tank, and iron dust, dust and impurities from outside do not seal well, which can lead to pump failure.
