Description
Technical Field
The utility model relates to a pump valve equipment technical field, concretely relates to induction port is at high-efficient horizontal self priming pump of inhaling fast of front end.
Background
Compared with other self-priming centrifugal pumps, the horizontal self-priming pump has the simplest structure because the pump is not provided with a check valve; the work is most reliable; the pump has the advantages of long working time without faults, convenient maintenance and use, small volume, light weight, high efficiency, large discharge capacity and high performance compared with pumps with the same caliber by taking special consideration on design.
The horizontal self-priming pump has more outstanding use efficiency as an emergency pump in industrial and agricultural production, emergency rescue and rescue, such as drainage of stagnant water and fire fighting. The horizontal self-sucking pump is widely used for city water supply in petroleum, chemical, metallurgical, mechanical, chemical fiber, food, energy and traffic industries, and also for agricultural irrigation and drainage. For transporting clear water or other liquids having a viscosity of less than 5 DEG E and a temperature of less than 80 ℃ and physical and chemical properties similar to those of clear water.
The self-priming tank is additionally arranged in front of the existing ZB type horizontal self-priming pump or centrifugal pump, the operation is complex, the self-priming time is long, and the service efficiency of the self-priming pump cannot meet the actual requirement.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model aims at providing an induction port is at high-efficient horizontal self priming pump of inhaling certainly fast of front end.
In order to realize the technical purpose, the utility model discloses a scheme is:
as preferred, a suction port is at the high-efficient horizontal self priming pump that inhales certainly fast of front end, including pump shaft and pump body, its characterized in that: the left end of the pump shaft is provided with an impeller, the right end of the impeller is provided with a partition plate, the right end of the partition plate is fixedly provided with a sealing box body through a screw, and an auxiliary impeller is arranged between the sealing box body and the partition plate; the pump shaft outer ring is provided with a shaft sleeve, and the shaft sleeve outer ring is provided with a mechanical seal.
Preferably, the front end of the sealed box body is provided with a machine-sealed washing water outlet, and the rear end of the sealed box body is provided with a high-pressure end outlet.
Preferably, the sub-impeller compresses air drawn into the chamber by rotating to form a water ring.
Preferably, a plurality of suction ports are annularly arranged on the surface of the impeller, and the suction ports and the partition plate form negative pressure.
The beneficial effects of the utility model, lead to the machine earlier and seal the cooling water, the pump is opened to the back, can realize from inhaling in 10 seconds, and pump efficiency is almost the same with the horizontal centrifugal pump, increases this from inhaling structure consumed power limitedly, does not exceed 3KW at most to large-scale self priming pump, and small-size self priming pump consumed power is lower. Compare and install from the priming tank before horizontal self priming pump of traditional ZB type or centrifugal pump additional, this new construction need not to irritate the pump, and is from inhaling the time faster, and pump efficiency is higher.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in FIG. 1, the embodiment of the present invention is
The utility model provides an induction port is at high-efficient horizontal self priming pump of inhaling certainly fast of front end, includes pump shaft 8 and pump body 1, its characterized in that: the left end of the pump shaft 8 is provided with an impeller 2, the right end of the impeller 2 is provided with a partition plate 5, the right end of the partition plate 5 is fixed with a seal box body 7 through a screw, and an auxiliary impeller 3 is arranged between the seal box body 7 and the partition plate 5; the outer ring of the pump shaft 8 is provided with a shaft sleeve 4, and the outer ring of the shaft sleeve 4 is provided with a mechanical seal 9.
The front end of the sealed box body 7 is provided with a machine seal flushing water outlet 7.1, and the rear end of the sealed box body is provided with a high-pressure end outlet 7.2.
The auxiliary impeller 3 compresses air sucked into the cavity by rotating to form a water ring.
The surface of the impeller 2 is annularly provided with a plurality of air suction ports 6, and the air suction ports 6 and the partition plates 5 form negative pressure.
In the specific implementation:
firstly, the machine seal cooling water is started, then the pump is started, the auxiliary impeller 3 rotates, negative pressure is formed between the partition plate 5 and the air suction port 6 (the air suction port 6 is arranged at the front end), air at the inlet of the pump body 1 is sucked from the balance hole of the impeller 2, machine seal flushing water flows out from the machine seal flushing water outlet 7.1 of the seal box body 7, the machine seal flushing water forms a water ring in the cavity of the seal box body 7 due to the rotation of the auxiliary impeller 3 to compress the air sucked into the cavity, the compressed air exhausts the air and the water from the high-pressure end outlet 7.2 at the rear end of the cavity of the seal box body until the air in the inlet pipeline of the pump and the pump body is completely filled with the liquid, the self-priming process.
The above, only do the preferred embodiment of the present invention, not used to limit the present invention, all the technical matters of the present invention should be included in the protection scope of the present invention for any slight modification, equivalent replacement and improvement of the above embodiments.
