Roots blower has been used for ten years in China, and its overall compactness has been reduced. The anchor bolts are loose, the muffler is brittle, and there is no gap between the spare parts of each enterprise. The deviation continues to expand, leading to the noise impact of Roots blower becoming more and more serious.
The solution for low pressure of Roots blower is usually to replace a larger motor, but the flow may be reduced, so the speed needs to be increased. The pressure of Roots blower is not the pressure generated by the development of Roots blower, but the pressure it can load. The low working pressure of Roots blower is actually due to the insufficient pressure and power construction under the normal operation of the blower. If we use it forcibly, the motor will be damaged. So in order to get more pressure, you must replace a stronger, more powerful motor.
The key reason why the working environment pressure of roots blower can be reduced is that the gap is constantly expanding, and there is no gap between the centrifugal impeller and the centrifugal impeller, between the centrifugal impeller and the plate wall, between the centrifugal impeller and the shell. Roots blower is a mechanical and technical equipment for forced steam transportation, The working and living pressure shown by Roots blower is the resistance generated by the front friction, which is what we often call condensing type now. The expansion of the gap will lead to serious gas backflow (internal leakage expansion), resulting in the reduction of air pressure and working pressure.
Other reasons for the reduction of working environment pressure: the reduction of airtightness, whether it is the Roots blower or the pipeline, if there is a leakage of steam, it will directly endanger the working and living pressure value of Roots blower. The leakage problem is relatively serious. Of course, the working and learning pressure cannot reach the rated value for standardization. Because the exhaust air volume is too small, the gap of roots blower is also large, the gap becomes larger, and the internal leakage is serious, which will lead to the reduction of exhaust air volume. The same is true. In the whole process of transporting steam, if the enterprise pipeline system leaks information, it will also reduce the exhaust air volume.
1. Check the fan
Check the fan outlet for failure, which causes fan blockage, bow and fan overpressure, and find the fan failure in time.
2. Check pipe
Check whether the fan pipe is blocked. Some pipes have too many elbows, which is easy to cause overpressure of the fan. In addition, there is too much oil in the fan pipe, which causes the diameter of the fan pipe C to narrow, causing overpressure of the fan. In this development, the system pipeline enterprise should be purged, and then the elbow of the fan can be reduced to reduce the pressure on the fan.
3. Select small number
If the selection is small and the air volume of the fan is sufficient, we can reduce the pressure of the fan by increasing the exhaust port.
