Description
Technical field
What the present invention relates to is magnetic drive pump pump shaft sliding bearing.
Prior art
The pump shaft of magnetic drive pump is arranged on pump cover by sliding bearing, and the end face outside of sliding bearing is combined with thrust bearing, and sliding bearing coordinates with axle sleeve and forms friction pair, plays radial support effect to rotor system; Sliding bearing and thrust bearing form friction pair, play axial limiting effect to rotor system.The two pairs of friction pairs are because of without self-lubricating property, therefore need to carry out lubrication with medium to it, when medium lubrication effect is bad, friction pair can generate heat and broken meeting matching surface rapidly, magnetic drive pump air horsepower is increased, even there is bearing, axle sleeve is damaged, cause bearing axle sleeve locking phenomenon, finally cause magnetic drive pump to lose efficacy.So the rationality of sliding bearing structure design is extremely important.
Prior art is see shown in accompanying drawing 4,5, that centrally line offers radial feed liquor groove a in the end face outside of the sliding bearing matched with thrust bearing, this radial feed liquor groove a is directly communicated with the axial pass trough b that sliding bearing endoporus is offered, and is introduced by medium in sliding bearing and carries out lubrication to sliding bearing and axle sleeve friction pair.
The lead channel structure that above-mentioned sliding bearing is offered is also imperfect, radial feed liquor groove a is directly communicated with the axial pass trough b that sliding bearing endoporus is offered, medium enters radial feed liquor groove a and axial pass trough b under the effect of separation sleeve chamber pressure, because the port of sliding bearing and axle sleeve is without liquid storage tank, this friction pair port does not have continuous print medium, therefore can not be lubricated fully, the port frictional heat of sliding bearing and axle sleeve is higher, easily burn-out of bearing is there is especially when starting shooting, even slag is fallen in breakage, and occurs the phenomenon of bearing locking.
Secondly, time in media as well containing impurity, after impurity enters radial feed liquor groove a, rotate because sliding bearing is relative with thrust bearing, impurity is subject to turning effort, although most of impurity flows through radial feed liquor groove a enter axial pass trough b, but some tiny particle occasionals are made a forcible entry between the friction pair of sliding bearing and thrust bearing, cause friction pair to damage, frictional force increases, and frictional heat raises and damages bearing.In like manner, when some impurity enter sliding bearing and axle sleeve port, because depositing nowhere, major part flows out via axial pass trough b, but some impurity are easy to by turning effort enters in sliding bearing and axle sleeve friction pair from end and cause bearing, boss failure.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, a kind of sliding bearing offering back flash on sliding bearing end face is provided.To improve the lubrication of sliding bearing and to prevent impurity from entering in sliding bearing and thrust bearing, sliding bearing and axle sleeve friction pair and cause bearing, boss failure.
Magnetic Drive Pump Sliding Bearing of the present invention, it is characterized in that offering the annular return groove 3 be communicated with axis hole 2 on the end face 1 of the sliding bearing A coordinated with thrust bearing, namely the axis hole 2 on the sliding bearing end face 1 coordinated with thrust bearing has annular return groove 3, the end face 1 of sliding bearing is uniformly distributed and has 2 or multiple lead channel 4 tangent with annular return groove 3, sliding bearing axis hole 2 offers axial pass trough 5.
Structure of the present invention is simple, and easily process, mounting type is installed identical with common magnetic drive pump pump sliding bearing.
After sliding bearing A of the present invention coordinates with thrust bearing B, lead channel 4, annular return groove 3, axial pass trough 5 form the runner of conveying lubricant medium, and annular return groove 3 forms current stabilization refluxing chamber.Because lead channel 4 is offer in tangent direction is uniform with annular return groove 3 on sliding bearing A end face, lead channel 4 has automatic guide drainage, medium rotates under the rotarily driving of interior magnet rotor and thrust bearing, even if pressure medium is very low, also can automatically enter in lead channel 4, medium tangentially enters in annular return groove 3 and forms stable rotary current, and make in annular return groove 3, to obtain sufficient medium, the friction pair port particularly making sliding bearing and axle sleeve be formed is completely infused in annular return groove 3 medium, the friction pair that sliding bearing and thrust bearing and axle sleeve are formed obtains good lubrication effect, and fully enter in the axial pass trough 5 on bearing axis hole and carry out lubrication, whole friction lubricating effect is improved greatly.
When containing impurity in fed sheet of a media, because lead channel 4 has drainage leading role, air flowability is good, and impurity can be entered in annular return groove 3 by lead channel 4 smoothly along with medium, follows medium and carries out stable revolution, play the crowded effect of buffering, then enter in axial pass trough 5 with medium and flow out outside sliding bearing A, and be not easy to enter in the friction pair of sliding bearing and thrust bearing, improve impurity removal ability, thus can not friction pair be damaged, reduce the occurrence probability of bearing locking.
