However, its main pressure cylinder generates a lot of heat during operation, which can easily change the sealing effect between the piston shaft and the inside of the main pressure cylinder. At the same time, it is inconvenient to clean the impurities accumulated in the liquid inside the main pressure cylinder. Utility Model Content
