Problems solved by technology
[0007] In order to overcome the problems of gas pollution and safety hazards caused by the centrifugal pump during the cleaning process, and the problem of dirty oil on the outer wall of the barrel, the present invention provides a centrifugal pump emptying and sewage discharge device. During the cleaning process of the centrifugal pump, adopt The sealed treatment method not only enables the discharged gas to be recovered and solves the problem of gas pollution, but also avoids the safety hazards caused by the open treatment method, and the dirty oil is no longer recycled by dumping , completely solved the problem of dirty barrel outer wall

Embodiment Construction
[0025] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.
[0026] Such as figure 1 As shown, the present invention proposes a centrifugal pump emptying sewage device, including a liquid storage cylinder 12, the upper part of the liquid storage cylinder 12 is provided with a mixture inlet and a gas outlet, and the lower part of the liquid storage cylinder 12 is provided with a first liquid outlet and a second liquid outlet. Liquid outlet.
[0027] When using the centrifugal pump of the present invention to empty the sewage device, the mixture inlet is communicated with the dirty oil outlet 17, and the mixture enters the liquid storage cylinder 12 from the dirty oil outlet 17 through the mixture inlet. During the cleaning process of the centrifugal pump 23, the liquid storage cylinder 12...

The invention provides a centrifugal pump release blowdown device which comprises a liquid storage cylinder, wherein a mixture inlet and a gas outlet are formed at the upper part of the liquid storage cylinder, and a first liquid outlet and a second liquid outlet are formed at the lower part of the liquid storage cylinder. According to the centrifugal pump release blowdown device, in a process of cleaning a centrifugal pump, a closed type treatment method is adopted, so that exhausted gas can be recycled, and the problem of gas purification is solved; in addition, potential safety hazards arising from an open type treatment method are avoided; and dirty oil is not recycled through a dumping mode, so that the problem of smudginess on the outer wall of a barrel is solved thoroughly.
Description
technical field [0001] The invention relates to a cleaning device for a centrifugal pump, in particular to a centrifugal pump emptying and sewage discharge device for discharging gas and dirty oil in the centrifugal pump. Background technique [0002] In the process of using centrifugal pumps to transport oil in oil production stations, according to the operating regulations, before the centrifugal pumps start, a certain amount of gas in the centrifugal pumps needs to be discharged to start smoothly. Therefore, the centrifugal pump in the oil production station is equipped with a special exhaust device to filter the hydrogen sulfide contained in the gas discharged from the centrifugal pump. It is mainly used in the exhaust process before the start of the centrifugal pump, or in the exhaust process before the centrifugal pump fails during operation and needs to be restarted. [0003] Such as Figure 4 As shown, a commonly used centrifugal pump 23 includes an inlet pipeline 1...
