Description

Vertical multistage sealless self priming pump

Technical Field

The utility model relates to the technical field of self-priming pumps, in particular to a vertical multistage sealless self-priming pump.

Background

At present, most of leakage-free pumps in the petroleum and chemical fields are shielding pumps or magnetic pumps, but the leakage-free pumps, the high-lift pumps and the self-priming pumps are required, and the pumps which are required to be filled for each start are not required urgently. At present, a small-flow high-lift leak-free pump has no self-priming function, and the pump needs to be refilled every time the pump is started. The pump perfectly combines the functions of small flow, high lift and self suction.

Disclosure of Invention

The utility model mainly solves the technical problems that the magnetic pump in the prior art needs to be filled with liquid every time, and the like, and provides a vertical multistage sealless self-priming pump which has a self-priming function and does not need to be filled with liquid every time.

The utility model provides a vertical multistage sealless self-priming pump, comprising: the device comprises a motor, an inlet pipeline, a pump and a barrel bag;

the output end of the motor is connected with the rotating shaft of the pump;

a cylinder bag is sleeved outside the pump; an inlet pipeline is arranged at one side of the upper end of the cylinder bag; an outlet pipeline is arranged at the outlet of the pump.

Further, the motor is connected with the pump through the connecting seat.

Further, the pump is placed vertically; the pump inlet of the pump is near the bottom of the cartridge.

Further, the interval between the pump inlet and the bottom of the barrel bag is as follows: 200-400 mm.

Further, the inlet pipeline is a bent pipeline.

Further, the vertical distance between the inlet pipeline and the pump inlet is as follows: 100-250 mm.

Further, the pump is disposed on the base.

The utility model provides a vertical multistage sealless self-priming pump, which is mainly characterized in that a cylinder bag is additionally arranged outside the pump. Before the pump is started for the first time, the barrel bag is filled with water. After the pump is started, water in the barrel bag is pressurized under the rotation action of the impeller and is discharged through the outlet and the outlet pipelines of the pump, and meanwhile, vacuum is formed in the barrel bag and the inlet pipelines, and liquid in a pool at the front end of the pump is pumped into the inlet pipelines and the barrel bag. Compared with the prior art, the pump achieves the purpose of self-priming. The pump is started again after stopping, and can run without refilling the pump.

Detailed Description

In order to make the technical problems solved by the utility model, the technical scheme adopted and the technical effects achieved clearer, the utility model is further described in detail below with reference to the accompanying drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the matters related to the present utility model are shown in the accompanying drawings.

As shown in fig. 1, the vertical multistage sealless self priming pump provided in the embodiment of the present utility model includes: a motor 1, an inlet pipeline 2, a pump 3 and a barrel bag 4;

the output end of the motor 1 is connected with the rotating shaft of the pump 3; the motor 1 is connected with the pump 3 through a connecting seat 7; the pump 3 is arranged on a base 6.

A cylinder bag 4 is sleeved outside the pump 3; an inlet pipeline 2 is arranged at one side of the upper end of the cylinder bag 4; an outlet pipe 5 is arranged at the outlet of the pump 3. The pump 3 is vertically arranged; the pump inlet 8 of the pump 3 is located near the bottom of the cartridge 4.

The distance between the pump inlet 8 and the bottom of the barrel bag 4 is as follows: 200-400 mm.

The inlet pipeline 2 is a bent pipeline. The vertical distance between the inlet pipeline 2 and the pump inlet 8 is as follows: 100-250 mm.

The embodiment of the utility model discloses a vertical multistage sealless self-priming pump, which comprises an electromagnetic part and a self-priming part, wherein the electromagnetic part and the self-priming part are combined into a whole novel pump. When the motor drives the rotating part of the pump 3 to rotate, the liquid in the pump and the barrel bag 4 flows out from the outlet pipeline 5 after being pressurized by the impeller, and the barrel bag 4 forms vacuum, so that the liquid at the inlet pipeline 2 can be supplemented into the barrel bag 4, and the purpose of conveying the liquid is achieved by circulation.

The front end inlet pipeline 2 of the barrel bag 4 is a bent inlet, and the height of the inlet 2 determines the liquid level in the barrel bag 4; when the pump is stopped and restarted, the barrel bag 4 and the pump are still filled with liquid, so that the purpose of self priming is achieved without pumping. The vertical multistage sealless self-priming pump has reasonable design and simple structure, can ensure no leakage and self-priming, has good self-priming effect, saves space and is very suitable for occasions where the pump is started frequently. The pump is convenient to install and reliable to operate.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments is modified or some or all of the technical features are replaced equivalently, so that the essence of the corresponding technical scheme does not deviate from the scope of the technical scheme of the embodiments of the present utility model.
