Air supply system for pump with air film mechanical seal:

①General purpose gas supply system

The block diagram of the general-purpose air supply system for pump mechanical seals is shown in Figure 4-16. All of the measuring instruments are equipped with additional contacts or switches to automatically trigger the alarm when the working condition exceeds the standard. 222 mechanical seal

②Special purpose gas supply system

Although the auxiliary system of the booster pump blocking (buffering) gas is easily available, in practice, it sometimes happens that the medium pressure is higher than the required blocking gas pressure. In order to solve this kind of phenomenon, a gas supply system equipped with a comprehensive pressure booster (namely a supercharger) is designed, as shown in Figure 4-17. The piston pump powered by natural gas from the supply network increases the pressure of the blocked gas to meet the requirements.
