FAQ of the waterjet cutting machine – Do you know what to do if the cartridge valve of the waterjet intensifier pump leaks oil?

There may be several reasons for the oil leakage of the cartridge valve of the waterjet intensifier pump:

1. The seal of the water jet spare parts cartridge valve is worn or aged, resulting in a decrease in sealing performance, and oil leaks from between the valve core and the valve sleeve or between the valve sleeve and the valve block.
2. The installation of the water jet spare parts cartridge valve is not correct, it is not tightened according to the specified torque, or the cavity of the valve block is not aligned, resulting in poor sealing between the cartridge valve and the valve block, and oil leakage from between the cover plate and the valve block.
3. The working pressure of the water jet spare parts cartridge valve exceeds the rated pressure, causing the spring of the cartridge valve to deform or break, or the gap between the valve core and the valve sleeve increases, and the oil leaks from the valve port or control port.
4. The working medium of the water jet spare parts cartridge valve is not suitable, which leads to corrosion or deterioration of the material of the cartridge valve, or the accumulation of impurities or air bubbles inside the cartridge valve, which affects the normal operation of the cartridge valve, and the oil leaks from various parts.
