How to deal with hydraulic cylinder malfunction urgently?
1. The valve core of the flow valve in the hydraulic cylinder is blocked, which can easily cause the hydraulic cylinder to malfunction. We need to check whether the oil in the hydraulic cylinder has contaminants and whether the valve body is worn.
2. When the piston rod and hydraulic cylinder are clogged, no matter what you do at this time, the hydraulic cylinder will not work. At this time, you need to check whether the seal of the piston rod is too tight, whether there are contaminants entering, and the axis line is not. Is there any failure of components that are not centered and easily damaged?
3. If the pressure controlled by the hydraulic system is too low, it will also cause the hydraulic cylinder to malfunction. At this time, it is necessary to check the control pressure source to ensure that the pressure value is in line with the specified value of the system.
4. If air enters the hydraulic system, the hydraulic cylinder will malfunction. At this time, you need to check the liquid level of the hydraulic oil tank, check the seals, filters and pipe joints are not too dirty, if this is the case, It is necessary to immediately replenish sufficient hydraulic oil to clean up the above-mentioned components.
5. In an environment where the temperature is too low, the viscosity of the hydraulic oil will increase, and the fluidity will be poor, so that the hydraulic cylinder will slow down and the movement will gradually fail. At this time, it is necessary to replace the hydraulic pressure with better viscosity and temperature performance. Oil, in the case of low temperature, the heater can be used to increase the oil temperature at startup.
