Hydraulic cylinder is a kind of hydraulic machinery, which can convert hydraulic energy into mechanical energy and carry out linear reciprocating movement or swinging movement. The problem of hydraulic cylinder arrears speed is very serious. The default speed is not not working, but can not meet the system requirements, so it cannot be checked, and there are many cases. Here is how to check the hydraulic cylinder default speed.
First of all, check whether the oil supply of the hydraulic cylinder is sufficient and whether the pressure is insufficient. If the parts in the hydraulic cylinder are damaged, resulting in reduced hydraulic cylinder flow and reduced speed, the damaged parts need to be replaced.
Second, the oil leakage of the hydraulic cylinder can be divided into internal leakage and external leakage. Internal leakage means that the wear gap of hydraulic parts is too large, and the parts in the system are very likely to fail, which can provide flow for the hydraulic cylinder and ensure normal operation. The main causes of leakage are loosening of pipe joints, sealing damage of pipe joints, etc. It is important to pay more attention to the invisible part of the pipe of the hydraulic cylinder.
Third, check whether the hydraulic cylinder has a speed control valve failure: if the valve heart of the speed control valve is stuck in the open position, there will always be a lot of oil from the speed control valve overflow into the tank, thereby reducing the flow into the hydraulic cylinder, resulting in low speed, and then discharge the speed control valve failure.
Fourth, due to other forces, the speed of the hydraulic cylinder is insufficient: the speed of the hydraulic cylinder decreases with the speed of different areas in the stroke, but the level of speed reduction will change with the different strokes. It may be caused by poor installation quality. The excess strength will increase the load and working pressure of the hydraulic cylinder, and the internal leakage will also increase, directly affecting the deceleration.
