Jet vacuum-pumping rapid water diversion device

Abstract

The invention discloses a jet vacuum-pumping rapid water diversion device comprising a diesel engine, an air compressor, a jet device, connecting pipes and other pipes, a ball valve, a floating ball switch and a vacuum pressure gauge. The water diversion device is characterized in that the jet device comprises a jet pipe and a Venturi pipe, and the air compressor is installed on the diesel engineon a supporting seat or a supporting centrifugal pump; an exhaust port of the air compressor is connected to an air inlet pipe of which the end is connected to the Venturi pipe, and the Venturi pipe is in screw joint with the jet pipe of which the side wall is provided with a jet pipe inlet; the jet pipe inlet communicates with a chamber of the supporting centrifugal pump, and the bottom of the Venturi pipe is connected to an exhaust hose; and the air compressor is driven by the diesel engine. According to the water diversion device, the time for the centrifugal pump ready to start can be shortened greatly, and the secondary self-priming working efficiency is improved; the production loss caused by long-time shutdown is decreased, and the labor cost is reduced; especially, the emergency rescue work can be quickly started, and the disaster loss is reduced; and meanwhile, artificial potential safety hazards can be avoided effectively, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a jet vacuum quick water diversion device matched with various dry-installed centrifugal pump equipment. Background technique [0002] In the field of general-purpose pumps, general non-submersible centrifugal pumps, except self-priming pumps with their own self-priming function and ordinary centrifugal pumps relying on positive pressure water intake, most dry-installed centrifugal pumps need to be configured Bottom valve, before starting for the first time, the pump needs to be filled with water to start. Although the pump is equipped with a bottom valve, the bottom valve has natural defects, which are mainly manifested in: 1. The bottom valve is heavy and installed under the liquid, which is not easy to install, monitor, maintain and repair; 2. The bottom valve is immersed in water for a long time. In the liquid, it is easy to cause corrosion, which will affect the sealing...

AI Technical Summary

Problems solved by technology

Although the pump is equipped with a bottom valve, the bottom valve has natural defects, which are mainly manifested in: 1. The bottom valve is heavy and installed under the liquid, which is not easy to install, monitor, maintain and repair; 2. The bottom valve is immersed in water for a long time. In the liquid, it is easy to cause corrosion, which will affect the sealing effect. If it is serious, it will not work when it absorbs water for the second time; 3. The solid particles generated in the production and process will enter the circulating liquid, and the accumulation and adhesion of solid particles in the bottom valve Attachment can prevent the bottom valve from being fully sealed, and the bottom valve will fail immediately; 4. Since the bottom valve is installed at the water inlet, the bottom valve itself will affect the water inlet area of ​​the pump and cause insufficient water supply
