The utility model can effectively prevent media from leakage, so that the maintaining time of media leakage is reduced by 80%.
Description
The utility model relates to a kind of magneto drive chemical centrifugal pump, and component parts comprises that the pump housing, impeller, pump cover, a bearing are arranged on the impeller rotating shaft of pump cover, and an end is fixed on the centrifugal pump suspension of electric machine casing and motor base, belongs to conveying equipment for fluid substances.
F type fiber glass epoxy chemical centrifugal pump is to be applied in the main chemical flow-process pump that industrial departments such as oil, chemical pharmaceutical, metallurgy, water treatment are carried Korrosionsmedium, and this pump is compared with stainless steel pump, and is simple in structure, cheap, corrosion resistance and good.But this pump also has an outstanding weakness, and that is exactly a leakage problem, can not get for a long time solving up hill and dale, has limited the use of F type fiber glass epoxy chemical centrifugal pump.Chinese patent 89210156.3 discloses a kind of anti-corrosive pump of leaking of preventing, this pump is taked in pump cover arranged outside auxiliary pump chamber, and is connected to the technical measures such as connecting tube of pump housing liquid outlet and auxiliary pump chamber mutually.Make fluid in the auxiliary pump chamber produce pressure, thereby stop main pump chamber medium to leak outside, obtain the between centers sealing from impeller shaft greater than main pump chamber fed sheet of a media.But the sealing of auxiliary pump chamber still needs to solve by the mechanical seal mode, and therefore existing needs periodical repair to change Sealing, can keep the deficiency of not leaking working state of the pump housing, influences the working efficiency of transporting system.
At, the above-mentioned deficiency of fiber glass epoxy chemical centrifugal pump technology, the purpose of this utility model provide a kind of Korrosionsmedium oil leakage that effectively prevents, simple in structure, the magneto drive chemical centrifugal pump hermetically sealed, reliable, that maintenance Sealing number of times obviously reduces.
The purpose of this utility model is owing to take following technical measures to realize.
The rear end of fixing glass steel seal closure, seal closure is provided with the axle bed of impeller rotating shaft, revolves axle for collapsable shaft on pump cover, NdFeB magnetic force piece is inlayed at the increase diameter of axle place that is positioned at seal closure in pairs, the sleeve shape coupling that seal closure outer installment and motor shaft are direct-connected is inlayed the NdeB magnetic force piece that closes with collapsable shaft magnetic force piece corner in the sleeve.
Magneto drive chemical centrifugal pump provided by the utility model is controlled at Korrosionsmedium in the hermetic overcurrent component, and Korrosionsmedium is moved within it, thereby reaches hermetically sealed effect of not leaking.Close in the magnetic field of sealing overcurrent shaft parts and the external magnetic field corner on the motor coupling, under the effect of motor rotating force, rotation external magnetic field effect internal magnetic field, magnetomotive drives the internal magnetic field rotation, and then impeller is rotated, aggressive medium is owing to the rotation of impeller obtains energy, and along with flow velocity increases, kinetic energy increases, when fed sheet of a media by when blade is dished out, rotating center forms negative pressure, and with the liquid level formation Negative Pressure Difference of suction side, the outer liquid of pump is pressed into the pump housing by suction lead.Like this, fed sheet of a media successively ground warp suction pipe enters the pump housing, and the impeller that is rotated continuously dishes out, and realizes course of conveying continuously.
The magneto drive chemical centrifugal pump, because the pump cover bearing of impeller rotating shaft is everywhere in full closeding state, the connecting part of the pump cover and the pump housing, seal closure is coated with sealer again, so the situation generation of not having again fed sheet of a media to leak.Because of the number of times that leaks maintenance reduces by 80%.
Accompanying drawing 1 is the structural representation of the attached centrifugal pump of magnetic force, accompanying drawing 2 is organigrams of running shaft, accompanying drawing 3 is plan views of the motor coupler of magnetic force chemical centrifugal pump, accompanying drawing 4 is plan views of motor coupler shown in the accompanying drawing 3, accompanying drawing 5 is organigrams of magnetic force piece, and accompanying drawing 6 is plan views of magnetic force piece shown in the accompanying drawing 5.Below in conjunction with accompanying drawing, further describe technical characteristics of the present utility model by most preferred embodiment.
The magneto drive chemical centrifugal pump is arranged on the impeller rotating shaft (8) of pump cover by the pump housing (1), impeller (2), pump cover (3), a bearing, and the centrifugal pump suspension (4) that an end is fixed on electric machine casing and motor base constitutes.
Wherein, be fixed with glass fibre reinforced plastics seal closure (6) on pump cover (3), the rearward end of seal closure is provided with the running shaft axle bed of impeller (2), built-in graphite bearing (11); Running shaft (8) is a collapsable shaft, and 4 NdeB(neodymium iron borons are inlayed at the increase diameter of axle place that is positioned at seal closure (6)) magnetic force piece (7); The sleeve shape coupling (5) that seal closure outer installment and motor shaft are direct-connected is inlayed the NdeB magnetic force piece that closes with collapsable shaft magnetic force piece (7) corner in the sleeve.(9) be motor, (10) are base.
In the present embodiment, NdeB(neodymium iron boron) the magnetic force piece is a watt shape, becomes abscission ring shape equidistantly to be configured in the increase diameter of axle place of running shaft (8), the corresponding 60 ° of central angles of watt shape magnetic force piece.
Adopt the made fiber glass epoxy magnetic force chemical centrifugal pump of technological scheme provided by the utility model, at flow Q=316M
