Abstract
The utility model relates to a new type vertical magnetic force driving unsealing self-priming pump, comprises a motor, a pump body, a impeller, a pump cover, a pump shaft , a shaft sleeve, a scaffold, a water inlet pipe and a water outlet pipe. The utility is characterized in that an outer magnetic steel is arranged on the terminal of the motor shaft which is arranged in the scaffold of the pump body; an inner magnetic steel, which is correspondingly arranged in the outer magnetic steel, is arranged on the top of the pump shaft; an insulating sleeve is arranged between the outer magnetic steel and the inner magnetic steel; the pump body is provided with a gas-liquid separation room on the upside thereof and a liquid storing room on the lower part thereof; a connecting hole is arranged between the gas-liquid separation room and the liquid storing room; the impeller is arranged on the connecting hole. The outer magnetic steel is provided with a reverse bowl shape. The inner magnetic steel is flat. An air valve is arranged on the water inlet pipe. The advantage of the utility model is that the non-contact transmission of torque is realized, thus whole sealing and non-leakage is achieved and the leakage problem of dynamic seal, feeding and mechanical seal is solved; the power loss of the hydrodynamic sealing auxiliary impeller and the cubage loss of the pump are reduced, thus the pump efficiency is improved; the pump is provided with self-priming function, so the bottom valve is not required to be arranged on the inlet.
Description
Technical field
The utility model relates to a kind of vertical self-sucking pump, particularly a kind of novel vertical magneto drive formula non-sealing self-sucking pump.
Background technique
Present domestic vertical self-sucking pump sealing technique, or the hydrodynamic seal structure that adopts, or adopt conventional filler sealing and mechanical seal.
1, adopt hydrodynamic seal sub-propeller outside dimension bigger, the air horsepower that it consumed is directly proportional with five powers of impeller outer diameter, so sub-propeller can consume power greatly, makes pump efficiency on the low side; And the easy air inlet of the oversize then pump chamber of sub-propeller, influence self-priming performance; Less then can the appearance leaks, and technology is difficult to hold.2, adopt packing seal and mechanical seal, the mechanical seal maintenance cost is higher on the one hand, and packing seal is leaked easily, does not realize proper nothing leakage on the other hand equally.Be difficult to the competent higher occasion of seal request that is applied to.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above of vertical self-sucking pump sealing configuration in the prior art, and a kind of novel vertical magneto drive formula non-sealing self-sucking pump is provided.The utility model designs a kind of novel vertical magneto drive formula non-sealing self-sucking pump, comprise motor, the pump housing, impeller, pump cover, pump shaft, axle sleeve, support, intake pipe, outlet pipe, it is characterized in that: on the motor the tip of the axis outer steel is arranged in the support on the pump housing, corresponding interior magnet steel is arranged in the outer steel, interior magnet steel is positioned at the top of pump shaft, between outer steel and interior magnet steel, separation sleeve is arranged, the gas-liquid separation chamber on pump housing top, in the bottom of the pump housing is liquid storage room, gas-liquid separation chamber and liquid storage room have intercommunicating pore, and impeller is positioned at the intercommunicating pore place.Outer steel is the bowl-type of back-off, and interior magnet steel is a pancake, and air valve is arranged on intake pipe.The utility model has the advantages that the non contact transmission that realizes moment, reach hermetically sealed, do not have and leak, solved the leakage problem of dynamic seal, filler and mechanical seal, reduce hydrodynamic seal sub-propeller power loss and pump volumetric loss, elevator pump efficient; Pump has self-absorption function, and import need not to install bottom valve.
Description of drawings
Accompanying drawing is a structural representation of the present utility model,
Below in conjunction with drawings and Examples the utility model is elaborated,
Embodiment
Comprise motor (omitting among the figure), the pump housing 1, impeller 2, pump cover 3, pump shaft 5, axle sleeve 6, support 7, intake pipe 8, outlet pipe 9 among the figure, it is characterized in that: on the end of motor shaft 10 outer steel 11 is arranged in the support 7 on the pump housing 1, corresponding interior magnet steel 12 is arranged in the outer steel 11, interior magnet steel 12 is positioned at the top of pump shaft 5, between outer steel 11 and interior magnet steel 12, separation sleeve 13 is arranged, the gas-liquid separation chamber 14 on the pump housing 1 top, in the bottom of the pump housing 1 is liquid storage room 15, gas-liquid separation chamber 14 and liquid storage room 15 have intercommunicating pore 16, and impeller 2 is positioned at intercommunicating pore 16 places.Outer steel 11 is the bowl-type of back-off, and interior magnet steel 12 is a pancake.Air valve 4 is arranged on intake pipe 8.
Utilize the magnetic force transferring power between outer steel 11 and the interior magnet steel 12 between motor shaft 10 and the pump shaft 5, reach hermetically sealed, do not have and leak, solve the leakage problem of dynamic seal, filler and mechanical seal, reduced hydrodynamic seal sub-propeller power loss and pump volumetric loss, elevator pump efficient.
Working principle: pump is behind normal starting, liquid that impeller 2 is deposited liquid storage room 15 and the air that sucks in the intake pipe 8 tunnel suck together, the liquid mixed gas is under the centrifugal action of impeller 2 high speed rotating, stator through impeller 2 is thrown into gas-liquid separation chamber 14, because flow velocity reduces suddenly, gas is different with the proportion of liquid, lighter gas is separated from mixed solution and is discharged from outside the pump from outlet pipe 9, the liquid of the degassing reenters active chamber to be mixed once more with impeller 2 inside inhaled air from suction line, under the effect of the rotation of impeller 2, make the pump housing 1 go into the certain degree of vacuum of interruption-forming very soon, thereby reach the purpose of self-priming.Because this pump has unique degassing function, so this pump can be carried the liquid that contains gas and bottom valve need not be installed.This pump is furnished with air valve 4, and during pump operation, air valve 4 cuts out, and realizes sealing; After the shutdown; air valve 4 is opened, and has destroyed the vacuum in the suction line, prevents that the liquid of shutting down in the pump chamber of back from flowing out through suction line because of siphonage; make the enough liquid of the interior preservation of pump chamber continue to finish the self-priming process, thereby realized drainage first, permanent self-priming.
The modern magnetics principle of these pump magneto drive certain applications, the non contact transmission of realization moment is to reach hermetically sealed, leak free infant industry pump.This pump is chemical industry, oil, food, pharmacy, metallurgy, printing and dyeing, papermaking, tens of kinds of industries such as plating thoroughly solve the run, drip, leak phenomenon of fed sheet of a media, found the ideal pump in " do not have and leak " workshop, be specially adapted to the conveying of strong acid, highly basic, inflammable, explosive, hypertoxic, volatile and precious liquid medium.
