Sichuan roots blower classification of large points!

　Sichuan Roots BlowerIt is a positive displacement blower with two three-blade impellers that rotate relative to each other in a space enclosed by a housing and a wall panel. Since each impeller adopts involute or epicoidal envelope, the three blades of each impeller are the same, and the two impellers are the same, which greatly reduces the processing difficulty. The machining of the impeller of Sichuan Roots blower adopts numerical control equipment to ensure that no matter where the two impellers rotate, a certain minimum gap can be maintained under the condition that the center distance between the two impellers is unchanged, so as to ensure that the gas leakage is within the allowable range.

What is the classification of Sichuan Roots blower? Let's analyze it together.

Sichuan Roots blower according to the number of impeller head: two-leaf Roots blower and three-leaf Roots blower. According to the purpose: kiln fan, gasification fan, aeration fan, etc. According to the type of medium: blower, gas blower, hydrogen blower, sulfur dioxide blower, etc. According to the conveying mode: direct blowing and belt blower, etc. According to the cooling method: air cooling fan, water cooling fan, countercurrent cooling fan, etc. According to the structure type: vertical blower, horizontal blower, vertical shaft blower, dense group blower, etc. According to the seal type: labyrinth seal, ring seal, packing seal and mechanical seal and other types of blower.

　　Sichuan Roots Blower: When it comes to the price of Roots blowers, there is a gap between the prices of various Roots blower manufacturers. As there are many manufacturers of different sizes, Xiaobian believes that there are four reasons: raw material prices, brand reasons, model reasons and supply and demand reasons. The specific information is summarized as follows.

1. The price of raw materials. The price of raw materials directly affects the price of roots blower. This year, many Roots blower manufacturers have raised prices many times, mainly due to the rise in raw material prices, including motor prices, casting prices, steel prices, labor, etc., which will directly affect the price of Roots blowers.

2. Brand reasons. Compared with foreign brands of Roots blowers, the price of foreign Roots blowers is generally higher than that of domestic brands, and the factors affecting the price are naturally related to the quality of the brand and the tariffs charged by the state. So, what is the main reason for the price difference of the domestic brand Roots blower in the three-leaf Roots blower? Quality is the main reason that affects the price, and the quality is naturally closely related to the design level, processing level, and raw material quality.

3. Model reasons.Sichuan Roots BlowerIt is a general term. Subdivided, there are many differences between three-leaf Roots blowers, such as: single oil tank and double oil tanks, air cooling and water cooling, air cooling single oil tank and water cooling double oil tanks, ordinary three-leaf Roots blowers and intensive three-leaf Roots blowers, direct drive and belt drive three-leaf Roots blowers, etc. These will affect the price of three-leaf Roots blowers, and decide which structure to adopt by our own selection parameters, that is to say by: air volume, pressure, speed, motor power, etc., these factors to determine.

4. Supply and demand reasons. Recently, the price of Roots blowers has been affected by supply and demand. This year, environmental protection activities are being carried out all over the country. All enterprises in the country have been affected, including the Roots blower industry. Affected by the environmental protection rectification policy, many small Roots blower enterprises have been closed for rectification. As a result, the supply is less than the demand, and enterprises with environmental protection qualifications have no choice but to raise prices.
