Abstract
The invention discloses a nonmetallic magnetic driving pump having an idle running function. The nonmetallic magnetic driving pump comprises a pump body and an impeller arranged in the pump body, wherein the impeller is connected to the front end of a spindle; a pump cover is hermetically connected to the back end of the pump body, and is connected to a motor bracket; a shaft coupling with a cylindrical inner cavity is fixedly connected to a motor output shaft; the inner wall of the front end of the shaft coupling is provided with a circle of magnetic steel; a spacer sleeve compressed onto the pump cover is coaxially arranged in the inner cavity of the shaft coupling; the two ends of the spindle are connected in the inner cavity of the spacer sleeve through a pressurized silicon carbide bearing; a rotor assembly matched with the magnetic steel is fixedly arranged on the middle periphery of the spindle. By adopting the nonmetallic magnetic driving pump, the possibility of fracture of a pump spindle due to idle running is avoided, the service life of the pump is prolonged, and the application range of the nonmetallic magnetic driving pump is enlarged.
Description
Technical field:
The present invention relates to a kind of air-portable nonmetal magnetic force driving pump that turns.
Background technique:
Nonmetal magnetic force driving pump is a kind of static seal without leaking chemical pump, and main shaft material is silicon carbide, ceramic material conventionally.Bearing material is for filling tetrafluoro silicon nitride, graphite.Be slip surface friction to grinding secondary, so possibility " artificially " negligence of operation, not by liquid feeding in magnetic force driving pump, or pipeline blockage causes magnetic force driving pump in " disconnected liquid " state.Make main shaft carry out slip surface friction at the bearing running up with pump cover upper bearing (metal), separation sleeve, due to aneroid in pump chamber, making main shaft sliding friction produce heat of high temperature cannot be taken away in time, makes main shaft fracture, causes separation sleeve to break.Once breaking, separation sleeve will there is dielectric leakage, befouling environment, and blast even on fire, causes heavy economic losses.
Summary of the invention:
For overcoming the defect of prior art, the object of the present invention is to provide a kind of air-portable nonmetal magnetic force driving pump that turns, stop to cause because of no load running the possibility of pump main shaft fracture, improve pump working life, expand the using scope of nonmetal magnetic force driving pump.
Technical solution problem of the present invention adopts following technological scheme:
Air-portablely turn nonmetal magnetic force driving pump, comprising:
The pump housing and be located at the impeller in the described pump housing, described impeller is connected in the front end of main shaft;
The back-end sealing of the described pump housing is connected with pump cover, and described pump cover is connected on electric machine support;
On motor output shaft, be fixed with the coupling that inner chamber is tubular, be provided with a circle magnet steel in the front inner wall of described coupling; In the inner chamber of described coupling, be also coaxially provided with the separation sleeve being pressed on described pump cover;
The two ends of described main shaft are connected to by air pressure SiC bearing in the inner chamber of described separation sleeve, and the middle part periphery of main shaft is installed with the rotor assembly with described magnet steel interoperation.
Described magnet steel is rare earth cobalt magnet, is fixed on the inwall front end of described coupling by screw.
Compared with the prior art, beneficial effect of the present invention is embodied in:
The present invention arranges air pressure SiC bearing at nonmetal magnetic force driving pump main shaft two ends, realize the support to it at main shaft two ends, the slip surface friction that changes two ends of rotor is line friction, effectively face is contacted with face to be converted to a little and contact with point, frictional force reduces, and bearing heats up little, eliminates bearing " locking " main shaft, cause main shaft breakage problem, fundamentally stopped nonmetal magnetic force driving pump because of air transport then cause pump damage possibility.
