How to determine the exhaust pressure and water depth of Roots blower?

How to determine the exhaust pressure and water depth of Roots blower? In the selection of roots blower, not only the pressure value, but also the air volume should be paid attention to. Only when the air volume matches the pressure can it be used. For roots blower, only when the air volume is continuous and stable can it meet the daily needs.

1. Select a reasonable installation position, reduce elbows, and make the water outlet face the pool.

2. Shorten the pipeline.

3. Expand the outlet pipe diameter.

4. The filter screen can be removed when the water inlet can be kept clean.

5. Adjust the axial clearance to prevent improper impeller ring and axial clearance. When using, adjust according to the factory instructions of the pump.

6. Timely remove pipe blockages. Remove the foreign matters left in the inlet pipe, impeller or flow passage of the guide housing.

7. Prevent the water pump from entering the air. If air enters the water pump, the water output will be reduced, and all sealing parts need to be inspected and maintained.

The deeper the water depth, the higher the pressure, the greater the motor power required by roots blower, so the water depth will directly affect the selection of roots blower. In addition, with the increase of water depth, the performance requirements for roots blowers are also greater, and the corresponding fan price is also higher. Therefore, when purchasing roots blowers, you must choose a model with high cost performance. If the water depth is more than 10 meters, it belongs to the high pressure state, and the performance requirements for Roots blower will also be higher.

At this time, it is generally appropriate to use two-stage series roots blower, and ordinary roots blower cannot meet the requirements.
