Abstract
The utility model discloses a water pump capable of suctioning low-level water automatically. The water pump comprises a water pump body; a suction inlet and an outlet are arranged on the water pump body. The suction inlet is connected with a standpipe with the caliber larger than the caliber of the suction inlet through a pipe. The bottom of the standpipe communicates with the pipe. A water filler and a suction pipe which can extend to a pond with the water level below the suction inlet of the water pump are arranged on the upper half part or the top of the standpipe. An inlet valve having the function of filtration is arranged on the port of the suction pipe extending in the pond. By adopting the water pump, at the beginning, water needs filing just once; subsequently, the water pump can pump water automatically every time when the water pump is turned on without needing to fill water again. The water pump operates as if the water level is higher than the suction inlet of the water pump, thus effectively improving the work efficiency of the water pump.
Description
Technical field
The utility model is about a kind of water pump, more particularly, and about a kind of water pump that can suck low water level water automatically.
Background technique
Water pump can be divided into vane type oil pump, positive displacement pump, jet pump by working principle, and wherein vane type oil pump can be divided into centrifugal pump, mixed flow pump, axial-flow pump, peripheral pump again; Displacement pump is divided into reciprocating pump, rotor pump; And jet pump is the high-speed jet driving fluid that produces by working fluid, and then by momentum transfer the energy of driven fluid is increased.Can be regardless of being any water pump, can only suck water level in use (can other liquid, different and different according to the environment that water pump uses) be higher than the water of water pump position, as shown in Figure 1, be lower than the water of water pump position, need be full of water at pump entrance pipe place in advance for water level, just can carry out work, but in the environment of frequent starting, it is pretty troublesome that the operation of this water filling will seem, causes the working efficiency of water pump low excessively.Specifically, when water level is higher than the water pump suction port, open inlet valve 16 and just can carry out the work of drawing water of water pump, when if water level is lower than the suction port 10 of water pump, then need filled with water in the suction port 10 of water pump, after only in the suction sleeve 15 of water pump, being full of water, the work of just drawing water, so each water pump need repeat same water filling program when repeated priming.
The model utility content
Just can automatically draw water when the purpose of this utility model is to provide a kind of to need water filling once can open afterwards at every turn and do not need to carry out again the water pump of water filling operation.
The water pump that can suck low water level water in the utility model automatically includes the water pump main body, on described main body, be provided with suction port and delivery outlet, be connected with the vertical tube of caliber at described suction port place by pipeline greater than described suction port bore, the bottom of described vertical tube is communicated with described pipeline, and the first half or top are provided with the filler and can feed the suction sleeve that water level is lower than the pond of described water pump suction port.
Described suction sleeve is provided with the inlet valve of tool filtering function at the port that feeds described pond.
The water pump that can suck low water level water in the utility model automatically in use only needs add a water and just can open water pump afterwards at every turn and can automatically draw water when beginning, and do not need to carry out again the water filling operation, the operation of drawing water when being higher than the water pump suction port with water level is the same, thereby can effectively increase the working efficiency of water pump.
Description of drawings
Fig. 1 is the structural representation of existing water pump;
Fig. 2 is the structural representation of water pump in the utility model.
Embodiment
The specific embodiment of the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 2, the main body of water pump that can suck low water level water in the utility model automatically is consistent with existing water pump structure, and the work that drives, principle are also consistent, therefore no longer describe in detail.And the water pump in the utility model also can be used to extract water liquid in addition, is not limited to extract water, is illustrated but the utility model is example with water.
Can suck automatically in the utility model low water level water water pump include water pump main body 1, in main body 1, be provided with and be used to drive the impeller (not shown) that water flows, this impeller is driven by the motor 3 that is located at main body 1 rear side.On main body 1, be provided with suction port 10 and delivery outlet 11, be connected with a vertical tube 13 at suction port 10 places by pipeline 12, the caliber of this vertical tube 13 is greater than the bore of water pump suction port 10, the bottom of vertical tube 13 is communicated with pipeline 12, the first half or top are provided with filler 14 and can feed suction sleeve 15 in the low water level pond 2, and 14 places are provided with the control valve 17 that can seal filler 14 in the filler.
For impurity in the anti-sealing is inhaled into water pump inside, go into the valve 16 that the place is provided with the tool filtering function at the mouth of suction sleeve 15.
The working principle of water pump that can suck low water level water in the utility model automatically is as follows:
When starting for the first time, in vertical tube 13, inject water, equal with the tip position of vertical tube 13, and the filler 14 of closure tip.Then open water pump, water in the vertical tube 13 is siphoned away by the impeller in the water pump, and in the internal upper part formation vacuum of vertical tube 13, this moment is by means of the effect of atmospheric pressure, the water level of suction sleeve 15 is risen, wait to draw water behind the certain phase, water constantly reduces in the vertical tube 13, and the water level in the suction sleeve 15 constantly rises, water in low level water pond 2 is completely gone in the vertical tube 13, in the time of in water is completely gone into vertical tube 13, but water just continuous supplementation to vertical tube 13, water pump is worked continuously.When water pump stops pumping, because of vertical tube 13 internal memories leave air, can not form siphon, the water in the vertical tube 13 can not flow back in the pond 2, thereby makes the state before vertical tube 13 returns back to turn on pump.
Wherein the concrete caliber of vertical tube 13 needs to decide with height according to the length of suction sleeve 15, specifically be to design in the following manner, if need aspirating, water pump is lower than the dark water of suction port h=2 rice, the void volume of then filling with in vertical tube 13 back suction sleeves 15 and the vertical tube 13 is V1, pressure is P1=10.33mH2O, quitting work at water pump, the maximum pressure in the vertical tube 13 is P2=P1-h (mH2O)=8.33mH2O when refluxing, by P1V1=P2V2, void volumes when beginning to reflux in the vertical tube 13 are V2=P1 V1/P2=1.24V1, and after the volume settings again according to highly calculating concrete caliber.
In sum, behind the water pump in using the utility model, only need water filling once, automatically draw water in the time of just can opening water pump afterwards at every turn, and do not need to carry out the water filling operation again, the operation of drawing water when being higher than the water pump suction port with water level is the same.
