HSPGL2-Pump Gas-Liquid Film Tandem Seal
Design Features
Tandem, multiple-spring, balance structure
Seal chamber has enough radial dimensions; primary seal on the side of the medium is double balance, counter-attack pressure designs, and nearly liquid film mechanical sealing.
Gas-film seaming on the side of atmospheric is safety sealing.
Between primary and secondary sealing access to clean nitrogen or instrument winds as a buffer gas, to provide main seal with certain back-pressure.
Trace media leaked by primary seal along with buffer gas go to torch or atmosphere, free from pollution to the environment; it is a kind of environmental protection sealing.
Primary seal once fail; secondary sealing can be as safety sealing in short time to ensure no leakage of medium to environment and high safety.
Container type structure and the overall installation accurate, convenient, knocked-down work are convenient.
