Reasons for Axis Breakage of Water Ring Vacuum Pump and Corresponding Measures
Axis Breakage of Water Ring Vacuum Pump:
After 2 years of use, water ring vacuum pump will present the phenomenon of excessive noise, excessive starting current, remarkable decrease in pumping capacity and vacuum degree. It is found that the scale inside the pump body is severe after the technical staff of our company disassembled and inspected. The reason for scaling is that the water contains calcium, magnesium and other carbonate substances. When the pump is heated and heated, its solubility decreases, and molecule-bound deposits form scales.
What measures should be adopted to avoid axle breakage?
Water ring vacuum pump
Through the analysis of the causes of shaft breakage of water ring pump, the following corresponding measures are adopted.
1. Revamping the original process equipment to reduce the content of impurities in acetylene gas trap: At the same time, the large well water of water ring vacuum pump is changed into circulating water to reduce the hardness of water quality.
2. Increase the radius of chamfering circle from 2.5 mm to 3.0 mm, and then reduce the stress convergence at the shoulder.
3. Selection of New Soft Packing
The original packing box structure of water ring vacuum pump was reformed, the cooling water pipe of the original packing box was removed, and a new CMS2000 soft packing was injected into the hole. This not only has good sealing performance, but also reduces the conflict power. Saving electricity and water.
After adopting the above measures, seven water ring pumps in acetylene process have been put into operation since 2003, and no shaft breakage has occurred. Since the revamping in 2003, there has been no axle breakage.
