Abstract

The utility model relates to a corrosion-proof pump which is used for pumping water and the corrosion-proof pump with corrosive liquid interworks on liquid surface. The utility model overcomes the defects that the existing water pump and the existing corrosive-proof pump can pump liquid only by adding leading water or leading liquid, the mount, the move and the operation of the sucking tube and the delivery lift tube are inconvenience and easy leakage, and an immersible pump is easy of burning out when the innersible pump is racing. The utility model is floated on the liquid surface; an impeller is immersed in the liquid directly, and the impeller drops down in company with the liquid level drops down when the impeller works; a pump casing is provided with a water baffle and a quiescence plate which overcome reverse rotation torque which is generated by a pump body when the impeller works; thus, the rotation of the pump body is prevented. The liquid is directly driven into a liquid outlet tube by the impeller and then the liquid is discharged. All the members which are connected with the liquid are resistant materials.

Description

Flotation type corrosion-proof pump

The utility model is to be used to draw water and to have the anti-corrosive pump that swimming on the liquid level of corrosive liquids worked, moved up and down with liquid.

At present, the shortcoming that other anti-corrosive pump exists, the one, the vacsorb formula need add diversion or draws liquid and could extract liquid out; The 2nd, the journey pipe of suction or lift pipe must be arranged and need pedestal, fitting operation inconvenience; The 3rd, connection pipe fitting is many, causes leakage easily, when extracting the strong liquid of acid, caustic corrosion, personnel is easily damaged; The 4th, submersible pump burns motor easily when no liquid dallies, and can not be used to extract corrosive liquids.

The utility model is in order to overcome the shortcoming of above pump, design a kind of float on the liquid level work, do not have suction pipe, can be with the novel corrosion resistant pump of liquid level height automatic lifting.It has only one and the close-connected liquid-discharging tube of pump, and liquid does not leak, and pump does not need to install, and is put in the work that gets final product on the liquid level.

Technical solution of the present utility model is: a kind of floating type anti-corrosive pump, it has had the pump case of floating function, immerse the impeller in the liquid, be installed in motor, closing cap and pump case base, motor shaft deadend assembling in the pump case, liquid can not be entered in the pump case.Its special way is that motor is installed in the pump case, and impeller is immersed in the liquid, and impeller working area and pump case inner sealing tightly do not have leakage, and liquid is directly squeezed into drain pipe by impeller and seen off.To the backward rotation moment of pumping action, keep the pump housing not rotate on liquid level when the manger board of pump case outside and the steadying plate on the base overcome wheel rotation, pump descends with liquid level, and the parts that contact with liquid all are the corrosion resistance materials.Realized the utility model floating type anti-corrosive pump.And the utility model does not have idle running, discharge capacity is big, lift is big, sealing is tight.

Below in conjunction with accompanying drawing an example of the present utility model is described in detail.

Fig. 1 is a plan view of the present utility model.

Fig. 2 is an External view of the present utility model.

Fig. 3 is that pump cover figure, Fig. 4 are that pump case figure, Fig. 5 are base figure, is auxiliary view of the present utility model.

As shown in Figure 1, base 2 assembles the working room that forms impellers 3 with closing cap 6; Base 2, closing cap 6, pump case 10, sealing gasket 16 and sealing gasket 17 assemblings form the floating type pump housing; Handgrip 13 is arranged on the pump cover 14, be installed in pump case 10 above, motor shaft 8 passes closing cap 6 and links with impeller 3, by sealed pipe 15, stuffing box gland 5 and spring 7 and sealing cover 6 and motor shaft 8 assemblings, the gap of sealed electrical arbor 8 and sealing cover 6; Drain pipe 12 is fixed on the closing cap 6.Motor shaft 8 impeller 3 are rotated, and liquid enters from liquid entering hole 1, squeeze into drain pipe 12 by the liquid wheel and discharge; To the backward rotation moment of pump housing effect, the pump housing did not rotate on liquid level when keeping pump work when manger board 11 on the pump case 10 and the steadying plate 4 on the base 2 overcame the rotation of liquid wheel; Filter screen 18 is installed on the base 2, filtration.Base 2, impeller 3, steadying plate 4, stuffing box gland 5, closing cap 6, pump case 10, manger board 11, drain pipe 12, loam cake 14, sealed pipe 15, sealing

gasket

16 and 17, filter screen 18 all are resistant materials.

As shown in Figure 3, equally distributed radiation hole 20 is arranged on the pump cover 14, its effect is that the heat that produces during with machine operation distributes.Drain pipe 12 stretches out from the liquid outlet pipe hole 19 on the pump cover, and power line enters in the pump case from liquid outlet pipe hole 19 and receives on the motor.As shown in Figure 4, the cylindrical normal is angled is connected for steadying plate 11 and pump case 10, when pump work, stops the pump housing to rotate with liquid effects.

Claims

1, a kind of floating type anti-corrosive pump, be to constitute by pump case, motor, impeller, base, it is characterized in that: motor is installed in the pump case.

2, floating type anti-corrosive pump according to claim 1 is characterized in that: manger board is arranged on the pump case, steadying plate is arranged on the base.

3, floating type anti-corrosive pump according to claim 1, it is characterized in that: motor shaft passes closing cap, with spring, stuffing box gland and sealed pipe sealing.
