Description
Technical field
The utility model relates to a kind of without bottom valve centrifugal water pump automatic start-stop device, and be the conductivity principle utilizing water, magnetic starter switch, automatic controller, high-low water level sensor and without bottom valve centrifugal pump realize the automatic start-stop of without bottom valve centrifugal water pump.
Background technique
Along with the continuous increase of coal enterprise's pit mining degree of depth, swallet is increasing, and the personnel putting into draining also get more and more, cause cost of labor and potential safety hazard more and more outstanding, add the burden of enterprise and the generation of security incident.
Summary of the invention
Under overcoming existing situation, along with the continuous increase of coal enterprise's pit mining degree of depth, swallet is increasing, the personnel putting into draining also get more and more, cause cost of labor and potential safety hazard more and more outstanding, add the deficiency of the burden of enterprise and the generation of security incident, the utility model provides a kind of without bottom valve centrifugal water pump automatic start-stop device, it can control automatically to the start and stop of without bottom valve centrifugal water pump, both alleviates business burden, additionally reduces the generation of security incident.
The utility model solves the technological scheme that its technical problem adopts: install high water level sensor and low water level sensor in exhalant region, between pipeline and Jet injector, solenoid valve is installed, between Jet injector and centrifugal pump body, solenoid valve is installed, electric contact pressure vacuum gauge is installed between intake pipe and centrifugal pump body, centrifugal pump body installs pressure gauge with electric contact, when water level rises to high water level sensor position, solenoid valve is opened, by Jet injector, vacuum pumping is carried out to centrifugal pump body, when vacuum reaches setting, centrifugal pump motor startup optimization, when water pipe line internal pressure value reaches certain value, pressure gauge with electric contact action, solenoid valve power-off is closed, water filling is carried out to water pipe, prepare for starting next time, when water level decreasing is to low water level sensor position, water pump quits work.
The beneficial effects of the utility model are, structure is simple, automatically can control, both alleviate business burden, additionally reduce the generation of security incident to the start and stop of without bottom valve centrifugal water pump.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
