Roots blower is a kind of volumetric air blowing equipment. Because the blades in the air chamber of roots blower are three pieces, it is called roots blower. Since roots blower is more stable than two blade roots blower, it has been fully applied in many fields such as petrochemical, building materials, electricity, smelting, fertilizer, mines, ports, light textile, food, paper making, aquaculture and sewage treatment, environmental protection industry, etc.
Temperature control is a very important problem in the use of Roots blower. Generally speaking, the outlet air temperature of roots blower during operation is usually not lower than 80 ℃, but the maximum shall not 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 roots blower.
In order to improve the service efficiency of roots blower and ensure the service life of roots blower, some measures can be taken. If roots blower is installed indoors, the operating temperature of roots blower can be reduced by installing air conditioner; If Roots blower is equipped with sound insulation device, the door of the sound insulation device 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 way to reduce the operating temperature of roots blower.
1. After Roots blower is installed, the fan may have some abnormal noise, which will gradually disappear after a period of operation. This is a normal phenomenon, and some new fans may also have unstable current. It is a normal phenomenon, which is caused by the viscosity of lubricating oil.
2. Roots blower cannot be used under overpressure, and it is easy to burn the motor under overpressure. It is necessary to check the pressure of roots blower every day.
3. The pressure gauge of Roots blower is usually closed, only when checking the pressure. Do not leave the pressure gauge open for a long time.
4. With regard to noise, the noise of dedusting roots blower has always been a concern, and the noise value of each fan is different. Even fans of the same model have different noise values, as long as there is no abnormal noise.
5. Generally speaking, if the pressure exceeds 58.8kpa, Roots blower needs to be cooled by water cooling. Of course, the case of air cooling is not excluded. If water cooling is used, the temperature of cooling water should not exceed 25 ℃.
6. For water-cooled roots blower, when starting. Start the water cooling pipe first, and then turn off the cooling water when shutting down the Roots blower.
7. If the roots blower is not used for a long time, the water-cooled roots blower shall drain the water in the water pipe. The air cooling roots blower shall also be cleaned and protected inside the roots blower.
I believe that after reading the above contents, you should also understand the precautions during the dedusting operation of Roots blower. I hope it will be helpful to you.
