According to an embodiment of the present utility model, vane pump top is provided with automatic control pressure vent, and the link position of water storage tank and suction pipe is higher than the position of automatic control pressure vent.
According to an embodiment of the present utility model, the top of water storage tank is provided with water injection hole, and the bottom of the second intake pipe is provided with weep hole.
According to an embodiment of the present utility model, the inside of vane pump comprises reflow pipe, and reflow pipe is horizontally disposed with, and it is being provided with backflow mortor operated valve near one end of vane pump outlet.
According to an embodiment of the present utility model, liquid level sensor is set in suction pipe.
According to an embodiment of the present utility model, also comprise electric control cubicle, electric control cubicle electrical connection liquid level sensor, import mortor operated valve, vane pump and backflow mortor operated valve.
Adopt the technical solution of the utility model, common vane pump (only a few cavitation performance poor pump except) can be transformed into self-priming pump, compared with traditional self-priming pump, there is higher hydraulic efficiency, compared with the vane pump of dress bottom valve, automaticity is high, and efficiency is higher, not only separate unit self-priming, and can realize many self-primings, can also use as vacuum pump temporarily, can take into account self-priming, efficient and automation.
Brief description of the drawings
In the utility model, identical reference character represents identical feature all the time, wherein:
Fig. 1 is the structural representation of the utility model self-priming vane pump unit.
Embodiment
Further illustrate the technical solution of the utility model below in conjunction with drawings and Examples.
With reference to Fig. 1, the utility model discloses a kind of self-priming vane pump set structure, this self-priming vane pump unit is formed by common vane pump transformation, its critical piece comprises vane pump 6, the first intake pipe 1, the second intake pipe 2, import mortor operated valve 3, water storage tank 4, suction pipe 5, liquid level sensor 8, electric control cubicle 7, outlet pipe 10, describes the structure of the utility model self-priming vane pump unit below in detail.
As shown in Figure 1, one end of the first intake pipe 1 is import, the other end connects import mortor operated valve 3, one end of the second intake pipe 2 connects import mortor operated valve 3, the other end connects the import of vane pump 6, the first intake pipe 1 and the second intake pipe 2 along continuous straight runs are installed, and the second intake pipe 2 tops connect water storage tank 4, and water storage tank 4 is connected by suction pipe 5 with the first intake pipe 1.
The working principle of self-priming vane pump unit of the present utility model is: the water storage tank 4 before suction flange injects a certain amount of clear water before pump startup, after starting, water and gas mix near vane pump 6 suction ports, gas is upwards discharged from outlet, water is got back to pump inlet by reflow pipe, near impeller inlet limit, gas-liquid is constantly being mixed, liquid flows in vane pump 6 and pipeline local circulation, and gas by endlessly from import discharged to outlet, thereby reach the object of self-priming.
According to above-mentioned principle, with reference to Fig. 1, the working state of self-priming vane pump unit of the present utility model is as described below.
First by the initialization of self-priming vane pump unit.Specifically, close import mortor operated valve 3 before startup, inject a certain amount of clear water, when water level reaches suction pipe 5 height, will overflow to import, the gas in vane pump 6 and the first intake pipe 1, the second intake pipe 2 roads is discharged by automatic control pressure vent 61.
Now, liquid level sensor 8 can detect current, can stop water filling.Open backflow mortor operated valve 91, start vane pump 6, now the water in water storage tank 4 will be discharged to outlet by vane pump 6.Along with the reduction of water level, gas will be inhaled into, and mix mutually with the current of outlet backflow near the impeller inlet of vane pump 6, accelerate air-breathing speed.
In the time that the first intake pipe 1 and the interior gas of the second intake pipe 2 all exhaust, water will flow in water storage tank 4 by suction pipe 5, and liquid level sensor 8 will detect current again.Now open import mortor operated valve 3, closing volume mortor operated valve 91, unit finishes start operating performance, enters into normal operation operating mode.All setting up procedures can be realized automatically and being controlled by electric control cubicle 7 above.
Can be found out by above-mentioned structure, self-priming vane pump unit of the present utility model is not only realized the self-priming of self, can also assist adjacent pump to realize self-priming.Owing to being that mixing wastewater with air is carried, water circulates in local return, and a small amount of water is drained with gas, can also use as vacuum pump temporarily.The more important thing is, common vane pump has been transformed into self-priming pump by the utility model, compared with traditional self-priming pump, has higher hydraulic efficiency.Compared with filling the vane pump of bottom valve, automaticity is high, and efficiency higher (bottom valve has certain hydraulic loss), can also use as vacuum pump temporarily.Self-priming vane pump unit of the present utility model has been taken into account self-priming, efficient and automation, is with a wide range of applications.
Those of ordinary skill in the art will be appreciated that, above specification is only one or more mode of executions in the numerous embodiments of the utility model, and not uses restriction of the present utility model.Any equalization variation, modification for the above embodiment and be equal to the technological schemes such as alternative, as long as meet connotation scope of the present utility model, all will drop in the scope that claims of the present utility model protect.
