Abstract
The utility model provides an automatic water diversion device of a sewage pump, which relates to the technical field of centrifugal separation. The top part of a centrifugal pump is connected with an inlet of a vacuum pump by a pipeline, a small transitional tank and a large transitional tank are connected in series on the pipeline, the small transitional tank is arranged near the centrifugal pump, and the large transitional tank is arranged near the vacuum pump; an electromagnetic valve is connected between the large transitional tank and the vacuum pump, a sensor of an electrode type liquid level switch is arranged in the small transitional tank, and the electrode type liquid level switch is connected at the working power supply end of the vacuum pump. At the central surface of a liquid level low pump, the automatic water diversion device of the centrifugal sewage pump has the functions of automatic linkage and no blockage particularly under the condition that a medium contains impurities.
Description
Technical field:
The utility model 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.
The model utility content:
In order to overcome above two weakness, the utility model provides a kind of new automatic water suction device, is used for the diversion of pump.
The utility model comprises 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, described small offence is crossed a jar close centrifugal pump and is 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 utility model 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 utility model 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 utility model.
Embodiment
As shown in Figure 1, the utility model is provided with a centrifugal pump 1 and a vacuum pump 2, between the import of the top of centrifugal pump 1 and vacuum pump 2, be connected by pipeline 3, and small offence of serial connection is crossed jar 4 and great transition jars 5 on pipeline 3, small offence is crossed jar 4 close centrifugal pumps 1 and is arranged that great transition jar 5 is arranged near vacuum pumps 2.
Connect two mutual back-to- back solenoid valves 6,7 between great transition jar 5 and vacuum pump 2, the pipeline 3 that is connected between great transition jar 5 and the solenoid valve 6,7 is metallic hose 3-1.
The sensor of electric pole type liquid-level switch 8 is set in small offence is crossed jar 4, and electric pole type liquid-level switch 8 is connected the working power end of vacuum pump 2.
Claims (3)
1. automatic water guide device of sewage pump, comprise a centrifugal pump and a vacuum pump, it is characterized in that between the import of the top of described centrifugal pump and vacuum pump, being connected by pipeline, small offence of serial connection is crossed jar and a great transition jar on described pipeline, described small offence is crossed a jar close centrifugal pump and is 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.
2. according to the described automatic water guide device of sewage pump of claim 1, it is characterized in that the solenoid valve that connects is two between great transition jar and vacuum pump, and arrange back-to-back mutually.
