From The Application Situation的意思|示意

看从应用情况 With the development of the petroleum industry, urban and rural residents in China's domestic fuel has been gradually replaced by coal-liquefied petroleum gas from wood, canned increasing application of liquefied petroleum gas. A result, such as Liquefied Petroleum Gas stations set up like bamboo shoots after a spring. At present the application of a single role of the Department of canned equipment rotor vane pumps, the use of two single-face seal mechanical seal, the side of a seal to prevent leakage of liquefied petroleum gas; side sealed bearings to ensure that the grease lubricated bearings. From the application situation, the existence of pump mechanical seal leakage and wear, tank taste great pollution to the environment; Moreover, the sealing operation to replace the cumbersome, not to repair. The principle author of the application of permanent magnet drive, in the absence of leakage magnetic centrifugal pump, valves, reactor applications in areas such as success on the basis of the expansion of this technology in the pump rotor, the design of closed gas pump, to achieve a non-sealed , all closed, absolutely sealed. In addition to the pump cylinder liquefied petroleum gas, but also transport liquid hydrocarbons, ammonia, propylene and other similar volatile nature of liquid and petroleum products.
