Does anyone have information on centrifugal blowers?

Sir, there is a lot of information about blowers in the forum. Please use the forum search function to find it.

Shaanxi drums are rarely used, and the heavy ones are mainly used. However, I have a classmate who works in design and after-sales service in Shaangu. I can contact him if necessary.

I have helped someone solve the problem of lubrication of a centrifugal blower. It is used for sewage treatment. Working conditions: 1. It requires long-term use without stopping the machine. 2. The bearing temperature is high. The outer temperature of the front bearing is 80-90 degrees, and the outer temperature of the rear bearing is 100-120 degrees. In summer, the temperature is even higher. 3. Grease was originally used for lubrication. Solution: 1. Grease was changed to lubricating oil. High temperature resistant grease is not a problem, the bearing speed is very high, and the heat dissipation/cooling performance of the grease is not good. 2. The bearing box is enlarged, and the flow of lubricating oil accelerates heat dissipation/cooling. 3. If it can meet the lubrication requirements, use No. 100 or No. 150 lubricating oil. The main bearing speed is very high, and the load is not large. 4. Use fully synthetic lubricating oil. Special lubricating oil, high thermal conductivity coefficient, large specific heat capacity, high temperature resistance up to 200 degrees. Suitable for use. After improvement, it can be maintenance-free for 2-3 years.
