Abstract
The utility model discloses a centrifugal water pump capable of exhaust, which comprises a motor, a pump seat, a magnetic ring, a cover board, a sealing loop, a blade fan, a pump rack, a pump mouth and screws, wherein, the pump seat and the magnetic ring are sheathed on a motor shaft in sequence; the pump seat is connected with the front end of the cover board; the tail end of the cover board is sheathed in the blade fan; the sealing loop is cushioned between the blade fan and the cover board; the blade fan and the pump rack are arranged in a pump chamber of the pump mouth in sequence; the outer surface of the pump mouth is provided with a water outlet, and the water outlet is communicated with the pump chamber; the pump mouth and the pump seat are fixed by the screws; the cross section area of the pump chamber in the pump mouth and the cross section area of a water inlet of the pump mouth is 1:0.3-1:0.8. Gases accumulated above the pump chamber in the pump mouth can be easily discharged from the water inlet of the pump mouth by the utility model, and the utility model satisfies the requirement that liquid rich in gases is extracted from the pump mouth instantly. The centrifugal water pump capable of exhaust has the advantages of simple technics, easy manufacture and high efficiency.
Description
Technical field
The utility model belongs to the water pump field, relates in particular to a kind of Exhaustible centrifugal water pump.
Background technique
Existing centrifugal water pump generally is made of motor, pump seat, leaf fan, pump mouth etc., the cross-section area of pump chamber is 1: 0.1～1: 0.2 with the cross-section area ratio of pump mouth water intake in its pump mouth, because pump mouth water intake area is little, when taking out the liquid (as soda) that is rich in gas, can produce a large amount of bubbles on the top of pump chamber, to making liquid can not fully enter pump chamber, cause and find time, water pump must be through repeatedly starting exhaust like this, and when the liquid gassiness reduced, water pump could normally pump liquid.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of technology is simple, easy processing, efficient height, can instantaneous extraction be rich in the Exhaustible centrifugal water pump of the liquid of gas.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of Exhaustible centrifugal water pump, comprise motor, pump seat, magnet ring, cover plate, seal ring, the leaf fan, pump bracket, the pump mouth, screw, pump seat, magnet ring is enclosed within on the motor shaft successively, described pump seat is connected with cover forward end, the cover plate tail end is enclosed within the leaf fan, be lined with seal ring between leaf fan and the cover plate, described leaf fan, pump bracket places the pump chamber of pump mouth successively, pump mouth outer surface is provided with water outlet, water outlet is communicated with pump chamber, and pump mouth and pump seat are fixed by screw, and the cross-section area of pump chamber is 1: 0.3～1: 0.8 with the cross-section area ratio of pump mouth water intake in the described pump mouth.
Preferably, the cross-section area ratio of the cross-section area of pump chamber and pump mouth water intake is 1: 0.55～1: 0.65 in the described pump mouth.
Preferably, the cross-section area ratio of the cross-section area of pump chamber and pump mouth water intake is 1: 0.6 in the described pump mouth.
The utility model compared with prior art, owing to increased the cross-section area of pump mouth water intake, the gas that accumulates in pump chamber top in the pump mouth can be discharged from pump mouth water intake easily, liquid is full of pump chamber and obtains energy from blade like this, satisfied the requirement that the transient liquid that is rich in gas is extracted out from the pump mouth, avoided repeatedly starting to extract the liquid that is rich in gas out; In addition, the utility model technology is simple, easy processing, efficient height.
Description of drawings

Fig. 2 is the parts explosion of Fig. 1.
Embodiment
In order to understand the utility model better, the utility model is done to describe further below in conjunction with accompanying drawing.
See also Fig. 1 and Fig. 2, Exhaustible centrifugal water pump of the present utility model comprises motor 1, pump seat 2, magnet ring 3, cover plate 4, seal ring 5, leaf fan 6, pump bracket 7, pump mouth 8, screw 9, pump seat 2, magnet ring 3 is enclosed within on the motor shaft 101 successively, pump seat 2 is connected with cover plate 4 front ends, cover plate 4 tail ends are enclosed within the leaf fan 6, be lined with seal ring 5 between leaf fan 6 and the cover plate 4, leaf fan 6, pump bracket 7 places the pump chamber 801 of pump mouth 8 successively, pump mouth 8 outer surfaces are provided with pump mouth water outlet 802, pump mouth water outlet 802 is communicated with pump chamber 801, pump mouth 8 is fixing by screw 9 with pump seat 2, in the pump mouth 8 cross-section area of pump chamber 801 can be 1: 0.3 with the cross-section area ratio of pump mouth water intake 803～1: 0.8, best ratio is 1: 0.6.
Please consult Fig. 1 and Fig. 2 again, during installation, motor shaft 101 stretches in the pump seat 2, cover upper magnetic ring 3, and load onto cover plate 4, seal ring 5, leaf fan 6, pump bracket 7, pump mouth 8 in order, pump seat 2 and pump mouth 8 usefulness screws 9 fixing getting final product.During work, motor 1 high speed rotating, drive 6 rotations of leaf fan by the magnet ring 3 that is enclosed within on the motor shaft 101, liquid enters leaf fan 6 then from pump mouth water intake 803 pump chambers 801, and the gas 10 that gathers is discharged from pump mouth water intake 803, reach the purpose of exhaust, liquid obtains energy through leaf fan 6, is dished out from pump mouth water outlet 802, reaches the purpose of drawing water.
The utility model increases pump mouth water intake 803, makes that the cross-section area ratio of pump chamber 801 and pump mouth water intake 803 is 1: 0.3～1: 0.8 in the pump mouth.When work, because pump mouth water intake 803 increases, make liquid can fully enter pump chamber 801, liquid specific gravity will be greater than specific gravity of gas in the pump chamber 801 like this, gas is just very fast to be extruded and to discharge from pump mouth water intake 803 from pump chamber 801, and the pressure that liquid was subjected to outside the pump mouth water intake 803 after gas was discharged from are discharged from pump mouth water outlet 802.
Although by above embodiment the utility model is disclosed, protection domain of the present utility model is not limited to this, all belongs to protection domain of the present utility model in the replacement that is equal to that does not depart under the utility model design condition.
