More than.
In structure diagram of the invention as shown in Figure 1, the invention mainly comprises pumps, magnetic driver, three, motor
Point, the pump includes by the pump housing 1, guide vane 2, pump cover, the body of sliding bearing 65,7 thrust disc of impeller, pump shaft 61, transmission shaft 36, connection
It is pressed before frame 21, sliding bearing 63, sliding shaft sleeve 62, thrust bearing component 66, antifriction-bearing housing 31, deep groove ball bearing 38, bearing
Lid 26, bearing rear pressing cover 32 form；The pump housing 1 is welded by forging, including outlet(discharge) flange connection neck and forges the pump housing,
After two components process respectively, sealing liquid welding is carried out first with argon arc welding, then strength solder joints is carried out using electric welding, finally passes through
Polishing, destressing are process, and are conducive to improve 1 bearing capacity of the pump housing using forging technology, increase the whole strong of the pump housing 1
Degree.Guide vane 2 is fastened on the body of sliding bearing 65 using hexagon socket head cap screw, is reduced after medium is pressurized due to directly hitting the pump housing 1
Caused water conservancy loss, plays the role of water conservancy diversion.The body of sliding bearing 65 is clipped in the middle by connection frame 21 and the pump housing 1, and slides
Bearing 63, sliding shaft sleeve 62 just increase supporting point in the body of sliding bearing 65 and on pump shaft 61, reduce rotor part
Bounce, reduces the friction stress of sliding bearing 63 and sliding shaft sleeve 62, extends service life.Transmission shaft 36 utilizes two depths
Ditch ball bearing 38 is fixed in antifriction-bearing housing 31, is fastened with connection frame 21.
Magnetic driver part is made of outer magnet rotor body 20, interior magnet rotor body 22 and non-magnetic separation sleeve 19.Every
It is fastened on the body of sliding bearing 65 from set 19, outer magnet rotor body 20 is connected on transmission shaft 36, and interior magnet rotor body 22 is mounted on pump
The upper shaft end of axis 61 makes magnet part mutually form the magnetic force systems that complete lotus root is closed.When inside and outside two magnetic pole is in heteropolar opposite,
The magnetic energy of magnetic system is minimum；When magnetic pole turns to, homopolarity is opposite, and the magnetic energy of magnetic system is maximum.After removing external force, the magnetic of magnetic system
Extremely mutually exclusive, magnetic force will make magnet be restored to the minimum state of magnetic energy.Motor 47 drives transmission shaft 36 to rotate, outer magnet rotor
20 synchronous rotary of body, magnetic field energy penetrate air-gap and namagnetic substance, drive synchronous with the interior work of magnet rotor body 22 that impeller 7 is connected
Rotation, realizes the non contact transmission of power, converts static seal for dynamic sealing, each sealing element is close by tooth profile metal pad 11, locking
Seal structure 12, the composition of pump shaft 61, interior magnet rotor body 22 are completely enclosed by the body of sliding bearing 65, separation sleeve 19.Separation sleeve 19 needs
Bear internal pressure, using Materials with High Strength, therefore can discharge pressure be up to the medium of 12Mpa, guarantee that separation sleeve is indeformable, pump
Body ne-leakage realizes zero leakage.
On supporting way, sliding bearing 63 on the body of sliding bearing, the body of sliding bearing and the pump housing 1, connection frame 21, every
It is fastenedly connected from set 19, enhancing rotor part operates rigidity, reduces bounce, vibration, noise.On in terms of the flushing, from pump chamber benefit
Clean media fluid is introduced with the flushing hole of the body of sliding bearing 65 and rinses sliding bearing 63, and lubrication sliding bearing 63 takes away cunning
The heat that dynamic friction pair and 19 whirlpool of separation sleeve damage generate, makes its sufficient lubrication and cooling, ensure that the safe handling of the pump housing 1.Magnetic
Power actuator part is made of outer magnet rotor body 20, interior magnet rotor body 22 and non-magnetic separation sleeve 19.Separation sleeve 19 uses
High-strength stud nut, tooth profile metal pad tight 11 are solid on the body of sliding bearing 65, and interior magnet rotor body 22, outer magnet rotor body 20 is complete
Separation.Separation sleeve 19 selects high strength titanium alloy to design, and ensure that separation sleeve 19 is indeformable in the case where bearing high internal pressure operating condition
It is not damaged.Because the intensity of titanium alloy is high, corrosion resistance is strong, so greatly reduce the thickness of separation sleeve, reduce magnetic loss and
Whirlpool damage, is effectively guaranteed the whole efficiency of pump, will not increase energy loss because of separation sleeve 19.Outer magnet rotor body 20 is directly
It is connected on transmission shaft 36, transmission shaft 36 is supported using two cylinder roller bearings, and antifriction-bearing housing 31 is provided with lubricating oil pair
Rolling bearing carries out oil lubrication, and transmission shaft 36 is connected to the motor by diaphragm coupling.Interior magnet rotor body 22 directly using keyway,
Locking nut is fixed on pump shaft.N is assembled in the interior magnet rotor body of magnetic driver to magnet (n is even number) by aligned transfer
22, on outer magnet rotor body 20, magnet part is made mutually to form the magnetic force systems that complete lotus root is closed.When by external force, inside and outside two magnetic pole
In heteropolar opposite, i.e. between two magnetic poles angle of displacement Φ=0, the magnetic energy of magnetic system is minimum at this time；When magnetic pole turns to homopolarity
Relatively, i.e., angle of displacement Φ=2 π/n between two magnetic poles, the magnetic energy of magnetic system is maximum at this time, and magnet generates movement, and magnetic is driven to turn
Son rotation.After removing external force, since the magnetic pole of magnetic system is mutually exclusive, magnetic force will make magnet be restored to the minimum state of magnetic energy,
Magnet rotor is also static with the disappearance of external force.When motor drives outer magnet rotor body 20 to rotate, magnetic field energy penetrates air-gap and non-
Magnetisable material drives the interior magnet rotor body 22 being connected with impeller 7 to make synchronous rotary, power non contact transmission is realized, by dynamic sealing
It is converted into static seal.Since pump shaft 61, interior magnet rotor body 22 are completely enclosed by the body of sliding bearing 65, separation sleeve 19, bearing capacity
It is very high, so separation sleeve 19 and seal assembly will not be deformed or be ruptured, Neng Goushi because of pressure height when pumping high-pressure medium
Existing zero leakage.
