During the use of Roots blower, temperature control is very important. Under normal circumstances, the outlet air temperature of Roots blower is usually not lower than 80 ℃, but it is better not to exceed 90 ℃. If the temperature is too high, the blades and air chamber of Roots blower will be distorted to a certain extent, which will affect the performance and efficiency of the blower, and various faults or directly shorten the service time.
The temperature control of roots blower is to reduce various use failures of roots blower and ensure the service life of roots blower. Measures can be taken: if the blower operates indoors, open the door and window for good ventilation. If it is hot in summer, it can be considered to effectively reduce the operating temperature of the blower by installing air conditioners; If the blower is equipped with a sound proof cover, the door of the sound proof cover can be opened to reduce the temperature; In addition, reducing the pipeline pressure loss and other pressure losses as far as possible is also an effective method to greatly reduce the operating temperature of the blower.
Roots blowers, especially trilobal roots blowers, are widely used in petrochemical, food, paper making, light textile, building materials, electricity, smelting, chemical, pneumatic conveying, aquaculture and sewage treatment, environmental protection industries and many other industries.
1. Normal temperature
The inlet air temperature of Roots blower should be lower than 40 ℃. If it is higher than this temperature, cooling treatment is required. After the Roots blower compresses the air, heat dissipation will occur, which will lead to an increase in the body temperature. The increased temperature is related to the pressure, which is about 100 ℃ under normal conditions.
2. Over temperature hazard
If the temperature of roots blower is too high, it will cause damage to seals, bearings and gears. The ultra-high temperature will have a greater impact on roots blower.
3. The super temperature of the roots blower is related to many factors, first of all, mechanical failure, such as serious impeller friction, serious bearing friction, belt slip, etc., which may cause the temperature of the roots blower to be too high. When we measure the temperature, we first observe whether the pressure and air flow of the roots blower are stable. If there is instability, it is generally a fault, Shutdown inspection is required.
The second is the impact of external temperature, such as poor heat dissipation, high inlet air temperature, and outlet pipes contacting high temperature components. For example, in the production of melt blown fabric, the outlet of roots blower is connected to the electric heater, which will affect the outlet temperature and also the fan temperature.
4. Solution for temperature exceeding
First of all, if it is a fault, we should first remove the fault. After the fault is eliminated, we should conduct temperature measurement to see if it meets the standard. Secondly, if it is affected by external factors, we should conduct cooling treatment. Under this condition, roots blower generally does not show fault problems, with stable air volume and stable pressure, This shows that there is no problem with the fan. We only need to solve the gas temperature.
I believe that after reading the above contents, you should also have some understanding of the solutions to the overheating of Roots blower. I hope it will be helpful to you.
