Abstract
The utility model relates to a jet type self priming centrifugal pump. A shaft (3) is sheathed on a pump shaft (2) in a heat mode, and the shaft (3) and the pump shaft (2) are put in a bearing body (5) together. A mechanical seal (4), a vane wheel (10) and a coupling (1) are installed, so the bearing body assembly is composed. A seal ring (9) is installed in a pump body (6), and the bearing body assembly is put in the pump body (6). An inlet seat (8) is connected with the inlet of the pump body (6), an outlet seat (7) is connected with the outlet of the pump body (6), so the jet type self priming centrifugal pump is composed. When the pump works, by the function of the mixing nozzle at a volute tongue, pumping air is enhanced, and the self-priming performance of the pump is improved.

The utility model relates to a kind of jet-type self-priming centrifugal pump
Background technique
The self-priming purpose of original self-priming centrifugal pump is that the centrifugal force by high-speed rotating impeller reaches, promptly under the high-speed rotating impeller effect, the air that impels inlet ductwork mixes with liquid in the liquid storage room, form gas-liquid mixture, when pump housing cut water, scraped, send into gas-liquid separation chamber, gas is discharged from pump housing outlet after gas-liquid separation, liquid is deposited in liquid storage room, reflux through return port, participate in the mixing of gas-liquid once more, the circulation of this process is carried out, until the inlet ductwork air is drained, finish the self-priming process and begin transfusion.Therefore, its suction capacity is relevant with impeller centrifugal force size, and the size of centrifugal force depends on the linear velocity of the maximum of impeller, and the maximum line velocity of impeller depends on lift of pump.For pump high-lift, small flow, self-priming performance is better, and for the pump of big flow, low lift, suction capacity is just poor, does not often reach requirement, for this reason, has proposed the jet-type self-priming centrifugal pump.
Summary of the invention
The purpose of this utility model provides a kind of jet-type self-priming centrifugal pump, by snail tongue place design mixing nozzle, improves the self-priming performance of pump, reaches usage requirement.
The purpose of this utility model is achieved like this: on the bearing 3 hot jacket ground pump shafts 2, together be contained in the bearing support 5, load onto mechanical seal 4, impeller 10, reach coupling 1 etc., form the bearing support assembly; Load onto seal ring 9, bearing support assembly in the pump housing 6 and pack in the pump housing 6, inlet port 8 links to each other with the pump housing 6 imports, and outlet port 7 links to each other with the pump housing 6 outlets, composition jet-type self-priming centrifugal pump.The pump housing 6 is a horizontal type structure, and the inlet/outlet of pump is higher than impeller 10 axis, at snail tongue place design nozzle.When pump work, under the centrifugal action of high-speed rotating impeller 10, form the pendular ring of gas-liquid mixture, at nozzle inlet S place, impel the pendular ring of gas-liquid mixture to change the inside of blade conduit M over to, because the effect of nozzle, gas-liquid mixture partly is pulled away, and is transported in the outlet connection of pump, carries out gas-liquid separation, gas after separating is discharged from the pump housing 6 outlets, liquid then flows back down into the import S place of mixing nozzle, participates in Air mixing once more, and the circulation of this process is carried out, air is drained, finish self-priming and begin transfusion.Adopt jet-type self-priming centrifugal pump structure, improved the vacuum capability of pump greatly, i.e. the suction capacity of self-priming centrifugal pump, and have only seldom influence when carrying liquid.
Adopt the utility model structure, can be widely used in petrochemical industry and shipborne equipment, improve the self-priming performance of pump, satisfy usage requirement widely, improve reliability of operation.

Specific embodiments
Shown in Figure 1, bearing 3 hot jackets together are contained in the bearing support 5 on pump shaft 2, load onto mechanical seal 4, impeller 10, reach coupling 1 etc., form the bearing support assembly; Load onto seal ring 9 in the pump housing 6, the bearing support assembly is packed in the pump housing 6, and inlet port 8 links to each other with the pump housing 6 imports, and outlet port 7 links to each other composing type jet-type self-priming centrifugal pump with the pump housing 6 outlets.
Shown in Figure 2, the pump housing 6 is a horizontal type structure, and the inlet/outlet of pump is higher than impeller 10 axis, at snail tongue place design mixing nozzle.By the mixing nozzle effect, improve the self-priming performance of pump.
