Abstract
The utility model relates to a self-priming type centrifugal pump, and provides a water pump for a solid-liquid separation equipment used in the industries of machinery, electronics, petroleum, chemical, pharmaceutical, brewing, plate-making and water drinking etc. Gradual demagnetization is easily occurred in the existing self-priming magnetic pump and magnetic steel is worn due to metal impurities of the liquid can be absorbed by the magnetic steel. The pump of the utility model adopts a built-in internal flow type self-cooling structure, and an impeller adopts a structure with block resistance, anti-winding and high flow, and also adopts a self-priming structure, thereby assembling and constituting the self-priming centrifugal pump, and the utility model has the functions of self-priming and idling resistance, and meanwhile has the advantages of long service life.
Description
Technical field
The utility model relates to a kind of centrifugal pump, particularly a kind of self priming centrifugal pump, Gu it be machinery, electronics, oil, chemical industry, pharmacy, a kind of water pump of brewageing, make a plate, using in the liquid-separation equipment of industry such as drinking-water.
Background technique
Self prime pump advanced in the prior art is by magnetic force self-priming pump produced in USA, its structure as shown in Figure 1, it is mainly by forming from suction tube I ', pump II ', motor II I ' and water output cylinder IV ', pump II ' comprises large and small cutwater 1 ', 2 ', magnetic drives 3 ', housing 4 ', cup 5 ', axle 6 ', bearing 7 ', impeller 8 ' and pump case 9 ', in use there are two big shortcomings in this magnetic drive pump: the one, and it can be along with the time demagnetizes gradually, the 2nd, the metal impurities in the liquid can be adsorbed on the magnet steel, the wearing and tearing magnet steel makes it to reduce working life.
Summary of the invention
The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of promptly have self-priming, anti-lost motion functionality are provided, and the while is the self priming centrifugal pump of long service life again.
The utility model realizes that the technological scheme that above-mentioned purpose adopted is: this self priming centrifugal pump comprises from suction tube, pump, motor and water output cylinder, pump comprises pump case and large and small cutwater, its structural feature is that impeller, impeller shaft, dynamic and static ring, axle sleeve and spring are installed in the described pump case, impeller shaft links to each other with motor shaft by shaft coupling, spring withstands the rotating ring in the dynamic and static ring, stationary ring in the dynamic and static ring is connected with rear end cover, pump case is connected with rear end cover and pump connection seat, and the pump connection seat is connected with motor.
Impeller shaft described in the utility model is connected with Cock screw with motor shaft by shaft coupling.
Rotating ring in the dynamic and static ring described in the utility model is fixed by fixing pin, seals by seal ring.
Dynamic and static ring liner axle sleeve of the present utility model and impeller shaft are isolated, and stationary ring is fixedlyed connected by fixing pin with rear end cover.
Pump case described in the utility model is connected by the motor bolt with rear end cover and pump connection seat, and is sealed by seal ring.
The utility model pump connection seat is connected by bolt with motor, and is sealed by seal ring.
The utility model compared with prior art has the following advantages and effect: 1, reasonable in design, novelty, good from absorption, before the start liquid is filled from suction tube first, and get final product self-priming when starting shooting once more, must draw the trouble of irritating liquid before having exempted each start; 2, anti-idle running is not influenced by disconnected liquid, can not damage impeller, water pump; 3, the dress in-flow was from cooling off structure in pump adopted, and long-term operation need not be lubricated, be cooled off; 4, impeller have anti-stop up, do not twine, flow is big, characteristics such as energy-efficient.
