Centrifugal pump cavitation and solve the process
phenomenon:
1 sewage pump, the use of temperature of about 80 degrees, pump pressure rose to normal after the pump outlet pump normal pressure,
About 10 minutes rapid decline in pump pressure, accompanied by noise, vibration, cavitation occurs Check the sewage station valve closed,
2 materials Pump material about 90 degrees easy to gasify the organic matter pump pressure rose to normal after the pump, due to feed a small pump outlet, the pump outlet opening is small, the pump pressure is normal,
About 30 minutes pump down, accompanied by noise vibration, cavitation occurs
This phenomenon occurs, we found that there are two situations one is the opening of the valve is not large,
The other is the pump inlet and outlet material temperature was significantly higher than the original found in 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 without energy Was promptly sent away,
The kinetic energy of the material is converted into heat energy, so that the material temperature increases, when reaching a certain temperature cavitation occurs in the pump body.
After analyzing the reasons for the clear solution to the pump outlet plus a return line, open the appropriate pump to open the back valve, there have been no cavitation
We started to manufacture Lighting Pole from 2001 and exported from 2003. We got CE certificate for Lighting pole from 2015.
Our firm introduced whole set of good-sized numerical control hydraulic folding equipment(1280/16000) as well as equipped with a series of good-sized professional equipments of armor plate-flatted machine, lengthways cut machine, numerical control cut machine, auto-closed up machine, auto-arc-weld machine, hydraulic redressing straight machine, etc. The firm produces all sorts of conical, pyramidal, cylindrical steel poles with production range of dia 50mm-2250mm, thickness 1mm-25mm, once taking shape 16000mm long, and large-scale steel components. The firm also is equipped with a multicolor-spayed pipelining. At the meantime, for better service to the clients, our firm founded a branch com. The Yixing Jinlei Lighting Installation Com, which offers clients a succession of service from design to manufacture and fixing.
