Abstract
The invention discloses an improved double-suction self-priming pump with a strong self-priming property, and belongs to combination of a double-suction pump and a self-priming pump and combination of a vacuum pump set and an automatic control system. An auxiliary vacuum pump set with the strong self-priming property introduces a new model of placing a mechanical float valve and a monitoring probe in an automatic control water diversion tank, and reliability of equipment is greatly improved. A vacuum pump constantly runs, the water level in the tank reaches a certain position, and the mechanical float valve can be automatically closed owing to buoyancy, so that water cannot enter the vacuum pump. Besides, a water stop valve is additionally arranged, water vapor is effectively stopped from entering the vacuum pump, and parts of the vacuum pump cannot be damaged due to entering of the water. The improved double-suction self-priming pump has ultrahigh suction and ultrafast self-priming functions, can run in a self-priming manner without water diversion and irrigation, can realize dry starting and automatic control, is particularly applicable to a locomotive integrated mobile pump station and can be widely applied to occasions such as flood-fighting and emergency rescue, flood drainage and fire fighting.
