What is the operating temperature and normal temperature of Roots blower
aeration Roots blower In the process of use, temperature control is very important. Under normal conditions, the outlet air temperature is often not lower than 80 ℃, but not more than 100 ℃. If the temperature is too high, this will have an impact on the performance and efficiency of the blower, various fault problems or directly shorten the use time and so on. Roots blower Under normal conditions, the operating temperature range is 80-100 ℃. In general, the temperature is directly proportional to the pressure and speed, in other words Roots blower The higher the pressure and speed, the higher the operating temperature. Next, Hong Guang made a detailed introduction to the operating temperature under normal conditions
With the increasing temperature in summer now, Roots blower The high temperature at the inlet and the temperature rise caused by the pressure rise during the operation of the fan make the surface temperature of the fuselage higher than other times. The specific normal temperature during operation is determined by the inlet ambient temperature + working pressure value.
I. Influence of model and pressure
Roots blower The larger the model is, the higher the temperature will be. In addition, under normal operating conditions, the temperature will increase by 1.1 ℃ for every 20 kPa pressure increase, and 0.9 ℃ for every 200 speed increase. Of course, the key lies in the adjustment of clearance, the advantages and disadvantages of bearings, and other factors. The same model and specification produced by different manufacturers will also have temperature differences. If the temperature is higher than 1000 degrees, it is higher than the standard temperature
2、 Affect quality
At the end of the day, Roots blower The higher the temperature of the fan, the more serious the impact on the service life of the fan. Therefore, we must always pay attention to whether the temperature is normal in the normal production and manufacturing process, and stabilize the temperature according to different conditions, which has achieved a more economical application method.
During operation, the temperature of the casing is directly related to the working environment and working output pressure. The wind pressure is not limited by the speed of the fan. No matter how the speed changes, the wind pressure can remain unchanged. The air volume is proportional to the fan speed. Roots blower constant torque load, its power saving rate is proportional to the speed drop, although different from the general fan, pump power saving rate is higher, but because of its large power, and as long as the furnace wall is not bad, it is working for 24 hours continuously, and the start-up time is also very long, so the potential of power saving is great and the cost of saving electricity is high.
Roots blower The temperature control is to reduce the use of fault, to ensure that Roots blower For example, if the blower is running indoors, open the door and open the window for good ventilation; if it is in hot summer, it can be considered to install air conditioning to effectively reduce the operating temperature of the blower; if the blower is equipped with a sound insulation cover, the door of the sound insulation cover can be opened to reduce the temperature; In addition, it is an effective method to reduce the pressure loss and other pressure losses of the pipeline as much as possible.
