Abstract
An automatic water guide device of sewage pump relates to the technical field of centrifugal separation. The top of the centrifugal pump and the inlet of the vacuum pump are connected through pipelines with which a small transition tank close to the centrifugal pump and a big transition tank close to the vacuum pump are serially connected; a solenoid valve is connected between the big transition tank and the vacuum pump; a sensor of electrode type liquid level switch connected on the working power supply end of the vacuum pump is arranged in the small transition tank. The invention is on the central surface of the level low pump; the automatic water guide device of centrifugal sewage pump has the function of self-interlocking and no blockage, especially in the condition that the medium has impurities.
Description
Technical field:
The present invention relates to the centrifugal separation technology field.
Background technique:
Centrifugal pump is the device that is used for pumping liquid, when the medium liquid level is lower than the median plane of centrifugal pump, generally adopts two kinds of patterns at present:
One, adopt manually-operable, draw a pipeline at the water pump top and connect, when treating that liquid level is higher than the pump top, close the vacuum pump inlet valve, stop vacuum pump, drive centrifugal pump with vacuum pump, owing to be manually-operable, very inconvenient.
Two, adopt self-priming pump, because this pump will have the structure that vacuumizes, changed original pump structure, the efficient of self-priming pump is generally lower.
Summary of the invention:
In order to overcome above two weakness, the invention provides a kind of new automatic water suction device, be used for the diversion of pump.
The present invention includes a centrifugal pump and a vacuum pump, between the import of the top of described centrifugal pump and vacuum pump, be connected by pipeline, small offence of serial connection is crossed jar and a great transition jar on described pipeline, and described small offence is crossed a jar close centrifugal pump and arranged that described great transition jar is arranged near vacuum pump; Connect solenoid valve between great transition jar and vacuum pump, the sensor of electric pole type liquid-level switch is set in small offence is crossed jar, described electric pole type liquid-level switch is connected the working power end of vacuum pump.
When the vacuum pump work, when canister was guided in the import of centrifugal pump, the sensor of electric pole type liquid-level switch turn-offed solenoid valve because of liquid level signal makes the work of electric pole type liquid-level switch with sewage, can realize that moment stops vacuum pump, opened the centrifugal pump working power simultaneously.Owing in pipeline that the great transition jar crosses jar to small offence and the great transition jar air is arranged, and the diameter of great transition jar is greater than pipeline diameter, when centrifugal pump is worked, after sewage compresses this section air, must leave one section space, solenoid valve can not contacted with the sewage medium.This just makes solenoid valve need not be with filter, has guaranteed the sealing reliability of solenoid valve simultaneously.When centrifugal pump is shut down, delayed time 5 seconds, open electromagnetic valve 10 seconds is removed vacuum, with sewage backflow in the big canister, prevents alluvial, stops up.The work drive motor that is connected with centrifugal pump, the work drive motor that is connected with vacuum pump, solenoid valve, motor type liquid-level switch all by electric control cubicle control, are realized chain automatically.Because employing is chain automatically, can realize automation one key operation, do not change centrifugal pump structure simultaneously, entire pump group efficient is improved.The present invention is at the median plane of the low pump of liquid level, and the automatic water diversion device of centrifugal sewage pump especially under the impure situation of medium, has chainly automatically, does not have the function of stopping up.
For enhanced leaktightness, solve the problem of two way sealed, the present invention connects two solenoid valves of arranging back-to-back mutually between great transition jar and vacuum pump.
Pipeline between described great transition jar and solenoid valve is a metallic hose, has solved centrifugal pump vibration and has caused the problem that solenoid valve vibrates, and prolongs the life-span of solenoid valve.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
