What are the most common failures of the hydraulic system of cutting machines and how to deal with them? [Ponse cutting machine]


The most common faults in the hydraulic system of cutting machines and their treatment methods are:

First, the valve core of the flow valve in the hydraulic cylinder of the cutting machine is blocked, it is very easy to cause the cylinder to fail. We need to check the oil in the cylinder or not, and check the valve body to be worn out.

Two. When the piston rod and the hydraulic cylinder are blocked, no matter how to do this at this time, the cylinder of the cutting machine can't operate. At this time, it is necessary to check whether the seal of the piston rod is too tight, there is no contaminant entry, and the axle line has no failure on the medium and easily damaged components.

Three, if the pressure of hydraulic system controlled by hydraulic cutting machine is too low, the action of the cylinder will fail, then check and control the pressure source to ensure that the pressure value is in accordance with the specified value of the system.

Four, if air enters the hydraulic system of the cutting machine, the oil cylinder will fail. At this time, it is necessary to check the liquid level of the hydraulic tank and check the seal. If the filter and pipe joint are not too dirty, if this is the case, the full amount of hydraulic oil should be added immediately to clean the components in the above.

Five, under the low temperature environment, the viscosity of hydraulic oil will become larger, then the mobility is not good, so that the movement of the cylinder slows down, the action will gradually fail, this time the need to replace the better viscosity of the hydraulic oil, in the case of low temperature can be used to improve the temperature of the start of the oil.
