Technical field
This utility model relates to a kind of magnetic drive pump being applicable to carry easy vaporized medium, belongs to magnetic drive pump field.
Background technology
Magnetic drive pump is with the basic theories of modern magnetics, applies magneticaction produced by permanent magnet material to realize contactless
A kind of new technique of transmission moment of torsion.During work, motor drives outer magnet rotor synchronous axial system, and outer magnet rotor is made by magnetic couple
With driving interior magnet rotor synchronous axial system, interior magnet rotor passes through axle impeller synchronous axial system, and then pumped (conveying) medium.
Between outer magnet rotor and interior magnet rotor, the separation sleeve by a metal separates, and operationally, the separation sleeve of metal is subject to
The cutting of rotating excitation field can persistently produce eddy current heat, and occurs that inside separation sleeve heat is assembled, if can not be to by heat
Take away, can cause magnetic drives assembly that high temperature failure phenomenon occurs.
At conventional art when solving separation sleeve internal heat rendezvous problem, it is by inwardly having at the extension of pump cover
Inlet opening, inwardly have liquid outlet at the interior Yan Chu of pump cover, the inlet opening of pump cover and the inner space of separation sleeve；Simultaneously at pump shaft
The end face of rear end axially inwardly has delivery hole, and the outside perforate in front end of pump shaft delivery hole is axial with the liquid outlet end of pump cover
Align.During impeller rotates, least a portion of pumped (conveying) medium enters the inner chamber of separation sleeve through the inlet opening of pump cover, then through pump
The delivery hole of axle is discharged from the liquid outlet of pump cover, is formed and flows through the interior closed circuit of separation sleeve inner chamber as it is shown on figure 3, to separation sleeve
Lower the temperature.The shortcoming of this inner circulation structure is when carrying easy vaporized medium, and in separation sleeve, the medium of vaporization is easily in isolation
Assembling occurs in set top, it is impossible to get rid of, thus circulation route in blocking so that separation sleeve cooling-down effect is poor, is easily caused magnetic force
Transmission component high temperature failure.
Utility model content
The purpose of this utility model be in order to solve the inner circulation structure of conventional magnetic pump carry easy vaporized medium time, right
Separation sleeve cooling-down effect is poor, therefore provides a kind of magnetic drive pump being applicable to carry easy vaporized medium.
The purpose of this utility model is achieved through the following technical solutions:
Of the present utility model a kind of be applicable to carry easy vaporized medium magnetic drive pump, including the pump housing, impeller, pump shaft, pump cover,
Interior magnet rotor, outer magnet rotor, separation sleeve, intermediate support and motor；
Impeller is fixed in pump shaft front end, and pump shaft is socketed with pump cover and interior magnet rotor；Outer, pump cover front end is fixed with the pump housing, makes
Impeller is encapsulated in the pump housing；The rear end of outer magnet rotor is connected with the spindle nose of motor, the side frame of motor by intermediate support and
Pump cover rear end is fixed, and makes to coordinate with interior magnet rotor lateral gap inside outer magnet rotor；Separation sleeve front end is fixed with pump cover rear end, every
From set rear end, interior magnet rotor is encapsulated, make interior magnet rotor and the isolation of outer magnet rotor；
Inwardly having inlet opening at the extension of pump cover, the inlet opening of pump cover connects with the outer wall of pump shaft；Simultaneously at pump shaft
The end face of rear end axially inwardly has delivery hole, and the outside perforate in front end of pump shaft delivery hole is axial with the inlet opening end of pump cover
Align；Pump cover axially has one group by liquid outlet circumferential in separation sleeve, make the inner chamber of separation sleeve with in the pump housing
Chamber connects.
During impeller rotates, least a portion of pumped (conveying) medium through the delivery hole of the inlet opening of pump cover and pump shaft enter every
In the middle part of the inner chamber of set, after medium is with the outside centrifugal motion of rotation of interior magnet rotor, go out liquid along the inwall of separation sleeve from pump cover
Hole is discharged to pump housing inner chamber, forms the interior closed circuit flowing through separation sleeve inner chamber, lowers the temperature separation sleeve.
Beneficial effect
Magnetic drive pump of the present utility model, changes into the interior closed circuit flowing through separation sleeve inner chamber in the middle part of the inner chamber of separation sleeve
Feed liquor, edge go out the structure of liquid, easily occur on separation sleeve top assembling, blocking when effectively solving conveying easy vaporized medium
The problem of interior circulation route, improves the cooling-down effect to separation sleeve, effectively extends the service life of magnetic drive pump.
