2. If the overflow valve in the hydraulic waste paper is deformed, it will seriously affect the main valve core blockage. The main valve core is blocked at the small opening, which will easily cause some of the pressure oil output by the hydraulic waste paper packing machine oil pump to overflow back to the oil tank. The flow of oil in the baler into the actuator is greatly reduced, which slows down the speed of oil supply.
3. The internal and external oil leakage is relatively serious. In rapid work, it is easy to cause the oil supply pressure to be too low, but the pressure is much higher than the oil return oil circuit. When the piston seal of the hydraulic waste paper baler cylinder is damaged, the baler The two sides of the oil cylinder are prone to accidents that cause excessive internal leakage, resulting in insufficient rapid movement of the hydraulic waste paper baler oil cylinder, and other parts are also prone to oil leakage.
