Some common faults and treatment methods for the hydraulic system of the cutting machine:

1. The valve plug of the flow valve in the hydraulic cylinder of the cutting machine is clogged, which is easy to cause the malfunction of the cylinder. We need to check whether the oil in the cylinder has contaminants and whether the valve body is worn or not.

2, when the piston rod and the hydraulic cylinder are blocked, no matter how to do it at this time, the cutting cylinder can not be operated. At this time, it is necessary to check whether the sealing of the piston rod is too tight, and whether there is any entry of contaminants, the axial line Is there any misalignment of the components that are centered and easily damaged?

3. If the pressure controlled by the hydraulic system of the hydraulic cutting machine is too low, the operation of the cylinder will be malfunctioned. At this time, it is necessary to check the control pressure source to ensure that the pressure value is in accordance with the system's specified value.

4. If there is air entering the hydraulic system of the cutting machine, the cylinder will malfunction. At this time, it is necessary to check the liquid level of the hydraulic tank, check the seals, whether the filter and the pipe joint are too dirty. If this is the case, It is necessary to immediately add a sufficient amount of hydraulic oil to clean the components mentioned above.

5. In the environment where the temperature is too low, the viscosity of the hydraulic oil will become larger, then the fluidity will be bad, so that the action of the cylinder will slow down and the action will gradually fail. At this time, it is necessary to replace the hydraulic oil with better viscosity and temperature performance. In the case of low temperature, the heater can be used to raise the oil temperature at startup.
