It consists of two dry gas seal static ring components and a moving ring. The oil side seal is usually a contact mechanical seal. Multi-spring balanced type, static type, suitable for high-speed operation. The principle of "gas blocking" is used instead of "liquid blocking", and the medium is sealed with a sealing gas with a pressure higher than the pressure of the sealed chamber by 0.2 ~ 0.3Mpa to ensure that the process medium achieves zero escape to the environment, meets VOC emission requirements, and is safe and environmentally friendly.
Trace gas enters the process. The seal has high requirements on the pressure of the sealed air source. It must always be higher than the pressure of the pump cavity at any time without interruption.
The seal adopts cartridge type, which is convenient for installation and removal. Sealed non-contact operation, energy saving, safety and environmental protection, reliable performance, simple operation, maintenance-free, and average service life of up to 3 years.
