The technical scheme includes that the magnetic centrifugal pump comprises a pump, a magnetic coupler and a driving motor. The magnetic coupler consists of a bracket, an outer magnetic rotor, an inner magnetic rotor and a non-magnetic-permeable isolating sleeve, the bracket is connected with the pump and the driving motor, the outer magnetic rotor, the inner magnetic rotor and the isolating sleeve are arranged inside the bracket, the outer magnetic rotor is arranged on an output shaft of the driving motor, a pump shaft supported by a sliding bearing is arranged inside the bracket, the inner magnetic rotor is mounted at the right end of the pump shaft, an impeller is mounted at the left end of the pump shaft, the inner magnetic rotor is arranged inside the isolating sleeve, an even number of pairs of magnets are respectively assembled on the inner magnetic rotor and the outer magnetic rotor of a magnetic actuator in an arrayed manner, and the magnets of the outer magnetic rotor are opposite to the magnets of the inner magnetic rotor. When the motor drives the outer magnetic rotor to rotate, a magnetic field drives the inner magnetic rotor to rotate synchronously by the aid of an air gap and the isolating sleeve so as to drive the impeller to rotate.
Description
Technical field
The utility model relates to a kind of magnetic centrifugal pump, is used for the sampling of product oil gathering line density measurement system.
Background technique
Traditional product oil gathering line density measurement system generally all adopts the magnetic-gear pump, has solved the leakage problem of common mechanical canned pump.Gear pump is a kind of of displacement pump, form two enclosed spaces by two gears, gear pump body and front and rear covers, when gear rotates, the volume in the space of the side that is out of gear is big from little change, form vacuum, liquid is sucked, and the volume in the space of gear engagement side is from diminishing greatly, goes and liquid clamp-oned in the pipeline.Suction chamber and discharge side separate by two gear meshing lines.Just because of the gear pump characteristics determined this pump to granularity in the medium require high, and in fact the product oil gathering line is in operation because a variety of causes has caused the granularity in the medium to can not get guaranteeing, thereby caused jam, the stall phenomenon of gear pump, had a strong impact on the density measure of product oil gathering line.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, and a kind of good sealing effect, leak free magnetic centrifugal pump are provided.
The technical solution of the utility model is: magnetic centrifugal pump, by pump, magnetic coupling and drive motor are formed, described magnetic coupling is by carriage, outer magnet rotor, interior magnet rotor and non-magnetic separation sleeve are formed, carriage connects pump and drive motor, outer magnet rotor, interior magnet rotor, separation sleeve is located in the carriage, outer magnet rotor is located on the output shaft of drive motor, pump shaft is by sliding supported condition and be located in the carriage, interior magnet rotor is installed in the right-hand member of pump shaft, impeller is installed in the left end of pump shaft, interior magnet rotor is located in the separation sleeve, the magnet of even-even arrange respectively be assembled in magnetic driver in, on the outer magnet rotor, the magnet of outer magnet rotor and interior magnet rotor is relative, when magnet rotor outside the motor driving rotates, magnetic field is by air air gap and separation sleeve, and magnet rotor rotates synchronously in driving, thus the impeller rotation.
The utility model is made up of pump, magnetic driver, motor three parts, and the critical component magnetic driver is made up of outer magnet rotor, interior magnet rotor and non-magnetic separation sleeve.When magnet rotor outside the motor drives rotated, magnetic field energy penetrated air gap and namagnetic substance, drove the interior magnet rotor that links to each other with impeller and did rotation synchronously, and the non contact transmission of realization power is converted into static seal with motive sealing.Because pump shaft, interior magnet rotor be by the pump housing, separation sleeve complete closed, thereby thoroughly solve " run, drip, leak " problem, eliminated the potential safety hazard that the oil-refining chemical industry is inflammable, explosive, poisonous, hazardous medium leaks by pump seal.
The permanent magnet of described magnet for making by rare earth permanent-magnetic material, its operating temperature range wide (45-400 ℃), coercivity height, magnetic direction have good anisotropy, and the phenomenon of also can not demagnetizing when homopolarity is close is a kind of good magnetic field sources.
Described separation sleeve selects for use high resistivity, high-intensity nonmetallic material to make, and effect is fairly obvious aspect the reduction eddy current.
The material of described sliding bearing has impregnated graphite, filled polytetrafluoroethylene, engineering ceramics etc.Because engineering ceramics has well heat-resisting, corrosion-resistant, crocking resistance, so the sliding bearing of magnetic drive pump adopts engineering ceramics to make more.Because engineering ceramics is very crisp and expansion coefficient is little, so the bearing play must not be too small, to avoid the seize accident.
Because the sliding bearing of magnetic drive pump is lubricated with the medium of being carried, so, can select for use different materials to make bearing according to different media and applying working condition.
The utility model is with using mechanical seal or gland sealed centrifugal pump to compare, and magnetic drive pump has the following advantages.
1. pump shaft becomes closed static seal by motive sealing, has thoroughly avoided dielectric leakage.
2. need not independent lubricated and cooling water, reduced energy consumption.
3. become synchronously by the coupling transmission and drag, do not have contact and friction.Power consumption is little, efficient is high, and have damping vibration attenuation function, when having reduced motor vibration the cavitation erosion vibration having been taken place for the influence of pump and pump to the influence of motor.
4. when transshipping, the relative slippage of inside and outside magnet rotor has protective action to motor, pump.
