Roots blower for special gas transmission

Special gas generally refers to marsh gas or anti-corrosion gas. Roots blower is not generally used for natural gas transmission. Roots blower is a pressurized fan, and the pressurization of natural gas is prone to explosion. MVR steam compressor, made of 2205 two-way stainless steel, is generally used for water vapor transmission. There are three important changes to Roots blower when conveying special gas.

1. The air outlet of the fan is connected to the casing through a pipe. The purpose of this is to prevent the air outlet pressure from being too high, resulting in gas leakage. The gas leakage can be effectively controlled through the return pipe.

2. Unless otherwise required by the customer, mechanical seal will be used, and labyrinth seal will be generally used, which is different from common nitrile rubber and skeleton oil seal, and the purpose is also to prevent gas leakage.

3. The over-current material is anti-corrosion coating, generally nickel plated. When Teflon coating is used, explosion-proof motor shall be selected as far as possible, and the transmission pipeline shall be safe.
