The low-pressure end of the booster 102 is connected to the hydraulic power source through the quick connector 103, which is convenient to connect and improves the installation efficiency. Among them, the quick connector 103 can be connected to the hydraulic power source through a pipeline at one end, and directly connected to the booster 102 at the other end. It can also be directly connected to the hydraulic power source at one end, and connected to the booster 102 through a pipeline at the other end; of course, it can also be connected to the hydraulic power source through a pipeline at one end of the quick connector 103, and connected to the booster 102 through a pipeline at the other end. The quick connector 103 is a prior art, which is a connector that can connect or disconnect the pipeline without tools, as long as it can be quickly connected or disconnected. Quick connectors can be divided into quick connectors for air, quick connectors for oxygen fuel gas, quick connectors for gas and liquid, quick connectors for oil pressure, quick connectors for inert gas, quick connectors for cooling water temperature oil, quick connectors for semiconductors, etc. The quick connector 103 here preferably uses a quick connector for oil pressure, which is easy and labor-saving. When disconnecting and connecting the oil circuit through the quick connector 103, the action is simple, saving time and manpower. In addition, using the quick connector 103 can also save oil. When the oil circuit is disconnected, the one-way valve on the quick connector 103 can close the oil circuit, and the oil will not flow out, avoiding the loss of oil and oil pressure.

[0035] Among them, ultra-high pressure is generally considered to be a pressure exceeding 100Mpa. Under ultra-high pressure conditions, non-shared bonds such as hydrogen bond aggregation, hydrophobic bonding, and ionic bonding in the macromolecular structure of organisms change, proteins denature, starch gelatinizes, enzymes are inactivated, cell membranes rupture, and components in the bacteria leak, life activities terminate, and microorganisms are destroyed and die.
