Problems solved by technology
[0002] Gas field water in oil and gas fields is mainly transported by sewage pumps. Due to the complex composition of gas field water, which contains a large amount of strong corrosive and toxic substances, when the pump is stopped, the gas field water remaining in the pump unit and the pipeline will leak out , and a large amount of toxic and harmful gases are volatilized, which seriously corrodes the sewage pump and the sewage pipeline used to transport gas field water, and also pollutes the surrounding environment

The invention discloses a clear water replacing system for a sewage pump. The clear water replacing system for the sewage pump is connected with a sewage delivering pipe, and a sewage switch is arranged on the sewage delivering pipe. The clear water replacing system for the sewage pump comprises a clear water tank and a clear water delivering pipe, wherein the clear water delivering pipe is connected with the clear water tank and the sewage pump; a clear water switch which can be turned on or turned off is further arranged on the clear water delivering pipe; after the sewage pump receives a stopping signal, a controller controls the clear water switch to be turned on and controls the sewage switch to be turned off; and after a predetermined period of time, the controller controls the sewage pump to stop working. After the sewage pump runs for a period of time and receives the stopping signal, the controller controls the clear water switch which is arranged on the clear water deliveringpipe to be turned on, and meanwhile controls the sewage switch which is arranged on the sewage delivering pipe to be turned off; and after a predetermined period of time, the controller controls thesewage pump to stop working, sewage in the sewage pump and the sewage delivering pipe are replaced by clear water, and the environment is protected further. The invention further discloses a clear water replacing method for the sewage pump and a sewage pump control system.
Description
technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a sewage pump clean water replacement system and method and a sewage pump control system. Background technique [0002] Gas field water in oil and gas fields is mainly transported by sewage pumps. Due to the complex composition of gas field water, which contains a large amount of strong corrosive and toxic substances, when the pump is stopped, the gas field water remaining in the pump unit and the pipeline will leak out , and a large amount of toxic and harmful gases are volatilized, which seriously corrodes the sewage pump and the sewage pipeline used to transport gas field water, and pollutes the surrounding environment at the same time. [0003] Therefore, how to provide a clean water replacement system for sewage pumps, which can clean the sewage pipelines in time, so that the sewage pumps and liquid pipelines are not corroded, thereby prolonging the service life of...
