But sometimes the corrosion-resistant water ring vacuum pump will also scale. What is the cause?

1. The pH value is high and the hardness is high.

2. The sealing degree of papermaking white water is increased, the content of insoluble substance is high, and the scale ion is accumulated.

3. The packing of corrosion-resistant water ring vacuum pump is widely used.

4. Temperature, water temperature rise, cooling system is not very good to use.

5. If the water circulation system is not cleaned and maintained regularly, it will aggravate the possibility of scaling of corrosion-resistant water ring vacuum pump.
