Product Detail

HEY -WEL Sealed EVG Rotary Gas Blowers are heavy duty rotary blowers designed with mechanical seals and High pressure (3.0kg/cm2), Accessories and Coherent part designed with Stainless steel.

The inside of the model is made within a cast iron casing, Teflon coated to avoid corrosion. The gear side and pulley side has its own oil reservoir,

The EVG features splash oil lube; it’s different between grease designs and advantage is high temperature, long-life.

Each unity is mechanically tested and given a 3.0kg/cm2 static leak test. HEY -WEL Sealed EVG Rotary Gas Blower hasn’t leakage concerns on use.

A 1/4” NPT purge port is provided at each seal for buffer gas application as required. After testing, the EVG is sprayed with a protective paint.


➲ DESIGN AND CONSTRUCTION FEATURES

1. Mechanical seals & 3.0kg/cm2 High pressure design.

2. Rigid one-piece cast iron casing.

3. 4pcs of Splash oil lubricated spur timing gears.

4. The Connecting pipes of basic are available for Customer demand.

5. Straight, precision machined Three- lobe rotors.

➲OPERATING PRINCIPLE

Three- lobe rotors mounted on parallel shafts rotate in opposite directions. As each impeller passes the blower inlet, it traps a definite volume of gas and carries it around the case to the blower outlet, where the gas is discharged. With constant speed operation, the displaced volume is essentially the same regardless of pressure, temperature or barometric pressure.

Timing gears control the relative position of the impellers to each other and maintain small but definite clearances. This allows operation without lubrication being required inside the gas casing. EVG install Vacuum Relief Valve in front-end of the suction silencer, to detect whether the air is blocking in inlet end, it should be avoid serious damage because of obstruction
