How to solve centrifugal pump cavitation?

Centrifugal pump cavitation phenomenon: 1 sewage pump, the use of temperature of about 80 degrees, pump pressure rose to normal after the pump outlet pump normal, about 10 minutes rapid decline in pump pressure, with noise, vibration, cavitation occurs, Inspection found that the sewage station valve is closed 2 Material pump, material about 90 degrees Easy to vaporize organic material Pump open to pump pressure rose to normal, due to feed a small pump outlet, pump outlet opening small, normal pump pressure, about 30 minutes Pumping Drop, accompanied by noise and vibration, the occurrence of cavitation phenomenon The above phenomenon occurs, you will find two situations: 1, a valve opening is not large; 2, the other is the pump inlet and outlet material temperature was significantly higher than the original Found in these two cases of cavitation occurs because the outlet valve opening is not enough or not caused when the outlet valve is not open or opening hours, the material obtained from the pump was not delivered in time, that is, the kinetic energy of the material is converted into Thermal energy, the material temperature rise, when reaching a certain temperature cavitation in the pump body.

Products features:

1. Very durable: we can use 50 years generally.

2. Noise-resistant: it is made of cast iron and with enameled coating on the surface. A bathtub is very heavy, and the material cast iron is very high, so when we fill water in the bathtub or shower trays, we won`t have a big noise.

3. Temperature - preservative: cast iron layer is 7-9mm. The specific heat of cast iron is comparatively high. So the water won`t cool down quickly.

4. very easy to clean: the enameled coating is applied on the cast iron base substrate under a high temperature 900 degrees for 3 or 4 times. So the shower trays or bathtub`s surface is very smooth, and comfortable to feel and easy to clean.

5. Acid and alkaline-resistant: when we put 10% acid on the surface, the gloss won`t be affected in any way.

6. Completely safe to our skin: the perfume or other lotion we normally use on the body, won`t affect the bathtub and shower trays, and it also won`t have static electricity or radiating elements.

I learn from a report, cast iron enameled sanitary ware is the safest type, because the bacteria are very difficult to exist on the surface.

7. Massive solid: we could have a very good artistic decoration effect.
