Description
Technical field
The present invention relates to oil filter, especially a kind of oil filter coupling magnetic drive pump.
Background technique
At present, the kind of drive of driven by motor oil pump all is traditional coupling transmission in the on-load tap-changer of transformer insulating oil online oil filtration machine, and coupling connects motor and oil pump, and this kind of drive exists following shortcoming during oil filter work:
1. owing to the long high speed rotating of transmission shaft at oil pump center, cause the wearing and tearing of shafting oil envelope easily, thereby cause the seepage of insulating oil.
2. the heating phenomenon of the coupling kind of drive of high speed rotating generation makes oil pump and motor damage easily.
3. there is the shortcoming that friction power loss is big, efficient is low, noise is big, vibration is strong in the coupling kind of drive of high speed rotating.
4. the coupling kind of drive runs into overload during phenomenon, thereby because motor and oil pump self can't be protected is damaged.
Summary of the invention
The objective of the invention is provides a kind of magnetic driver that utilizes to drive the oil filter coupling magnetic drive pump that axle rotates in order to solve above-mentioned the deficiencies in the prior art.
In order to achieve the above object, the oil filter coupling magnetic drive pump that the present invention is designed, comprise motor and pump, described motor has motor shaft, described pump comprises pump case, the a pair of pitch wheel rotor and the device that goes rancid, it is characterized in that being equipped with on the described motor shaft outer magnet rotor, the wheel shaft of one of them gear rotor is coaxial and be equipped with and interior magnet rotor that outer magnet rotor matches with motor shaft, have oil inlet passage and oil discharge passage on the described device that goes rancid, described pump case has receiving cavity, described a pair of gear rotor is positioned at receiving cavity and receiving cavity is separated out suction chamber and discharge side, and described pump case and the described device that goes rancid are assembled together and describedly advance, oil discharge passage respectively with the suction chamber of pump case, discharge side is communicated with.
Outer magnetic changes through the driven by motor rotation, thus magnet rotor rotation in driving.Interior magnet rotor drives the wheel shaft rotation, the driven gear pump operation, and insulating oil is through the feeder connection that goes rancid, be in the wheel tooth mouth, quickened the back by the gear rotor rotation and discharge, the channel outlet of going rancid connects oil purifier, reaches insulating oil like this and has the effect that certain speed arrives at oil purifier.Electric power machine and pump can separately be assembled, and be fixing.
Improve and replenish as the further of said structure, the present invention also comprises the combination in any of following additional technical feature or these features:
Magnet rotor is with the lubricating cup cover that is installed on the described device that goes rancid outward in described, the outside of described pump case fix one pump case and outside separation sleeve between the magnet rotor.By the sealed envelope of lubricating cup cover and separation sleeve, make oil pump form a seal, insulating oil can not leak.Annular space zone between interior magnet rotor and the separation sleeve is lubricated, is washed and cooled off in simultaneously oily circuit insulation, has avoided the magnet of high speed rotating to produce high temperature, thereby magnet rotor is lost magnetism, and causes magnetic driver to lose efficacy.Experiment showed, with the insulating oil to be medium, can make the annular space regional temperature maintain 5-8 ℃.
Described lubricating cup cover is a uncovered cylindrical body, and described cylindrical body open-mouth edge outwards forms a toroidal surface, has through hole on the described toroidal surface, some fastening pieces pass described through hole and are connected on the device that goes rancid, this structure is good sealing effect not only, and convenient fixing, firmly.
Described outer magnet rotor concave side wall forms a circular groove, and described separation sleeve is embedded in groove.Separation sleeve is wrapped in the outer magnet rotor good positioning effect.
The axle bearing of magnet rotor is in the device central position of going rancid in described being equipped with, and described wheel shaft one end passes the device that goes rancid and connects described interior magnet rotor, and the other end is fixed with described gear rotor, and is easy for installation, is in the central position, rational in infrastructure, operates steadily.
Described oil inlet passage and oil discharge passage are " 7 " font, and an one port is located on the outer peripheral surface of the device that goes rancid, and the another port is located at the device that goes rancid by on the end face of gear rotor side, and processing is simple, and it is fast to walk speed oil.
The described device that goes rancid, pump case and separation sleeve corresponding position are provided with mounting hole, and the mounting hole of described correspondence is equipped with screw rod, and is stable, and the screw rod serial connection mounts and dismounts more convenient.
Described pump case and gear rotor material are teflon, rub resistance, corrosion-resistant.
Magnet rotor and outer magnet rotor match by even-even magnet provided thereon respectively in described.Is that even number is assembled into magnetic driver by the rule arrangement with n to magnet n, makes magnet part form the magnetic force systems of complete coupling.Interior magnet rotor and the outer magnet rotor composition magnetic force systems that is coupled, to be in heteropole relative when inside and outside two magnetic poles, i.e. angle of displacement Φ between two magnetic poles=0, this moment, the magnetic energy of magnetic system was minimum, when magnetic pole turns to homopolarity, i.e. angle of displacement Φ=2 π/n between two magnetic poles, this moment magnetic system the magnetic energy maximum.After removing external force, because the magnetic pole of magnetic system repels mutually, magnetic force will make magnet return to the minimum state of magnetic energy, so magnet produces motion.
The oil filter coupling magnetic drive pump that the present invention obtains has following advantage:
1. by the motive sealing on the coupling kind of drive, become closed static seal, thoroughly avoided the leakage of insulating oil.
2. annular space zone between interior magnet rotor and the separation sleeve is lubricated, is washed and cooled off in oily circuit insulation simultaneously, avoided the magnet of high speed rotating to produce high temperature, need not independently Cooling Design and oiling agent, effectively reduce manufacture cost and energy consumption, reduced pollution environment.
3. become synchronously by the coupling transmission and drag, do not have contact and friction, power consumption is little, efficient is high, noise is low, has the damping shock absorption effect.
4. protective function, when the driven member of magnetic driver ran into overload situations, the driving and driven parts of magnetic driver can slippage under the effect of alternating magnetic field, has guaranteed that motor and oil pump can not damage under the situation of overload.
