Double-end dry gas seals arranged in series. The first-level seal adopts the inner intake spiral groove technology and adopts a statically compensated outflow structure to keep solid particles and liquid away from the seal end face. The seal also has a certain anti-backpressure function and is safe Sex is higher.
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 environmentally safe.
The working medium sealed on the medium side and the atmospheric side are externally introduced with filtered sealing gas, and a small amount of the sealing gas enters the process flow. This seal has high requirements on the sealed air source. The pressure of the air source must be higher than the pressure in the pump cavity at any time, and there must be no interruption.
Suitable for API, ANSI and DIN large diameter sealed chambers.
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.
