Abstract

The utility model relates to a strong self-suction and double-suction type self suction pump, and belongs to a combination of a double suction pump, a self suction pump, a vacuum pump unit and an automatic control system. The strong self-suction and double-suction type self suction pump has the functions of super-high suction lift and super-quick self suction. By taking DN300 diameter as an example, the 1m suction lift can be realized within about 30 seconds, and the self suction type dry starting and the automatic control are realized without requiring the water drainage and irrigation. When a main pump is started, the vacuum pump unit can also start; after the vacuum degree is raised until water can flow out of the main pump, the vacuum pump unit can automatically stop. In the use process, when the vacuum degree is decreased to the low level, the vacuum pump unit can automatically start; after the vacuum degree is increased to the high level, the vacuum pump unit can automatically stop. A vacuum degree control system does not interfere the running of the main pump, and only performs the auxiliary function. The pump has the advantages that the anti-dry grinding structure design is adopted, the mechanical seal of the water pump can realize dry running for more than 30 minutes without damage, the shallow water, gas and water mixing liquid and the like can be sucked, and the pump is widely applied to the occasions of flood-fighting and emergency rescues, flood drainage, firefighting, and the like.
