Abstract
The utility model discloses a water pumping system used for pumping water in a water storage pool into a sizing agent pool. The water pumping system comprises a water pump communicated with the water storage pool. The water pump is communicated with a water pumping pipeline. The water pumping pipeline is communicated with the sizing agent pool. A one-way valve preventing water backflow is arranged on the water pumping pipeline. Due to the fact that the one-way valve is arranged on the water pumping pipeline, when the water pump stops working, even when water pressure inside the water pumping pipeline is higher, water in the water pumping pipeline cannot flow back to affect the water pump, and therefore the service life of the water pump is prolonged.
Description
Technical field
The utility model relates to a kind of pumping system.
Background technique
In prior art by the pumping system in the water suction slurry pool in wet pit, comprise the water pump being connected with wet pit, described water pump is connected with pumping conduit, described pumping conduit is connected with slurry pool, in the time that water pump quits work, because the hydraulic pressure in pumping conduit is larger, can there is water backflow phenomenon, thereby can cause damage to water pump, thereby affect the working life of water pump.
Model utility content
The purpose of this utility model is to overcome the defect existing in prior art, and a kind of pumping system is provided, and after can preventing that water pump from quitting work, then water pump is caused to damage because the hydraulic pressure in pipeline refluxes water, extends the working life of water pump.
For achieving the above object, the technical solution of the utility model has been to provide a kind of pumping system, be used in the water suction slurry pool in wet pit, comprise the water pump being connected with wet pit, described water pump is connected with pumping conduit, described pumping conduit is connected with slurry pool, is provided with the one-way valve that anti-sealing refluxes on described pumping conduit.
As preferably, between described pumping conduit and described water pump, be connected by water return pipeline, the diameter of described water return pipeline is less than the diameter of described pumping conduit, on described water return pipeline, is provided with gate valve.
As preferably, on described gate valve, be provided with controller opens or closed manual lever.
As preferably, between described one-way valve and described pumping conduit, be connected by adpting flange.
As preferably, between described adpting flange, be provided with seal ring.
Advantage of the present utility model and beneficial effect are: by one-way valve is set on pumping conduit, in the time that water pump quits work, even if the hydraulic pressure in pumping conduit is higher, the water in it can not occur to reflux yet water pump is impacted, thereby extends the working life of water pump.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Wherein: 1, water pump; 2, pumping conduit; 3, one-way valve; 4, water return pipeline; 5, gate valve.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of pumping system, be used in the water suction slurry pool in wet pit, comprise the water pump 1 being connected with wet pit, described water pump 1 is connected with pumping conduit 2, described pumping conduit 2 is connected with slurry pool, on described pumping conduit 2, be provided with the one-way valve 3 that anti-sealing refluxes, between described pumping conduit 2 and described water pump 1, be connected by water return pipeline 4, the diameter of described water return pipeline 4 is less than the diameter of described pumping conduit 2, on described water return pipeline 4, be provided with gate valve 5, on described gate valve 5, be provided with controller opens or closed manual lever, between described one-way valve 3 and described pumping conduit 2, be connected by adpting flange, between described adpting flange, be provided with seal ring.
Working principle: while drawing water, gate valve on water return pipeline 45 is closed, water pump 1 enters the water in wet pit in slurry pool by pumping conduit 2, owing to being provided with one-way valve 3 on pumping conduit 2, after water pump 1 quits work, water in pumping conduit 2 can not reflux, now gate valve 5 can be opened, the interior unnecessary water of pumping conduit 2 can flow back in water pump 1 by water return pipeline 4, because the diameter of water return pipeline 4 is less than pumping conduit 2, therefore the flow of recirculation water is less, also less to the damage of water pump 1.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (5)
1. a pumping system, be used in the water suction slurry pool in wet pit, comprise the water pump being connected with wet pit, described water pump is connected with pumping conduit, described pumping conduit is connected with slurry pool, it is characterized in that: on described pumping conduit, be provided with the one-way valve that anti-sealing refluxes.
2. pumping system as claimed in claim 1, it is characterized in that: between described pumping conduit and described water pump, be connected by water return pipeline, the diameter of described water return pipeline is less than the diameter of described pumping conduit, on described water return pipeline, is provided with gate valve.
