This product is a new type of gas delivery machine developed by Zibo Botong Fan Co., Ltd. based on the development trend of two-stage gas stoves and combined with single-stage gas stoves. It fundamentally solves the problem of relying on imported or Roots blower for high noise and flow that cannot be adjusted for a long time. Since its launch on the market, the operation has proven that the machine has low noise, a flat performance curve, a large flow regulation area, high efficiency, low energy consumption, and especially good sealing of the fan, which has been highly praised by users.

This machine can rotate clockwise or counterclockwise, with outlet angles of 0 degrees, 90 degrees, and 180 degrees respectively. Users can choose according to their actual pipe distribution needs.

2、 Purpose:

This machine is specifically designed for gas pressurization in factories, mines, gas stations, blast furnaces, coke ovens, converters, as well as gases with strict airtightness such as ammonia and biogas.

3、 Structural features:

This type of fan is a plate welded integral structure, mainly composed of the following components:

1. Impeller. The impeller is the heart of the entire fan, so the blade profile of the fan is optimized and designed according to the new high-efficiency fan theory. The material is made of stainless steel or alloy according to different needs, which has good corrosion resistance and sufficient strength. After the impeller is formed, it undergoes static and dynamic balance correction, and the accuracy is G4 level (higher than the national standard G6.3 level).

2. Chassis. Made of high-quality carbon steel welded to the machine base as a whole, ensuring the rigidity of the entire machine. The casing is coated with epoxy resin to enhance corrosion resistance; The upper part of the casing is equipped with a G3/4 steam pipe interface, and the lower part is equipped with a G3/2 drain valve; The inlet and outlet flanges of the fan adopt standard flanges to facilitate the connection of user pipelines.

3. Sealing group. This seal mainly uses soft packing and centrifugal sealing, with no vulnerable parts inside the seal. The structure is very simple, the effect is particularly reliable, and it is easy to replace.

4. Motor. The motor matched with this machine adopts Y series or explosion-proof motor, with explosion-proof grade d Ⅱ BT4 and protection grade IP44
