High temperature magnetic pump according to incomplete statistics, China now has more than the size of the pump business revenue of nearly 20 million yuan more than 2000, which is fully capable of producing high temperature magnetic pump less than 50 companies, which is why the high temperature magnetic pump large gap the reason why, is specialized in producing parti pump CQB-G type high temperature magnetic pump. Author magnetic pump production technology and market orientation issues, visited the Shanghai magnetic pump plant, the plant is responsible to the author describes the key technology of high temperature magnetic pump production. This pump seemingly production process is not complicated, but the temperature can truly solve the run, run, drip, leak of ills, not every pump manufacturing business has technology done bits. There are two high-temperature magnetic pump cooling, air-cooled and water-cooled. Air-cooled relatively better resolve, water-cooled manufacturing process is relatively difficult to higher manufacturing cost is also large, and production processes to meet industry standards Ministry of Chemical and petrochemical industries to develop.
