The sealing material is usually selected based on the chemical compatibility with the medium being transported, but even if the seal and the medium are chemically compatible, the physical interaction between them can cause the hydraulic baler to leak. Seal failure is caused by the medium drilling out of the seal and rupturing the seal from the inside. This action causes the seal to peel off or rupture, forming a leakage path. This problem is particularly serious under high temperature and high pressure, but even under less severe operating conditions Will happen too.
According to the different reasons why air enters the waste paper baler system, the following points should be paid attention to in the use and maintenance:
1. An exhaust valve should be installed on the upper part of the oil cylinder of the waste paper baler to facilitate the exhaust of the air in the cylinder and the system. The oil temperature change and load change that the waste paper baler adapts to are larger than the use of a throttle valve, and the application flow rate is larger. The parallel hydraulic cylinder synchronization circuit of the control valve is simple in structure and low in cost, so it is widely used.
2. Try to prevent any pressure in the waste paper baler system from being lower than atmospheric pressure. At the same time, use a particularly good sealing device. If it fails, replace it in time. Use screws to tighten the pipe joints and all joint surfaces and clean them in time. The oil filter at the inlet of the fuel tank of the waste paper baler.

3. Frequently check the height of the liquid oil level in the oil tank of the waste paper baler. Its height should be kept on the oil mark scale line. Separate with partitions.
