Abstract
The invention provides a magnetic pump sliding bearing. The magnetic pump sliding bearing is characterized in that a shaft hole (2) in the sliding bearing end face (1) matched with a thrust bearing is provided with an annular backflow groove (3), two or more liquid intake grooves (4) tangent with the annular backflow groove (3) are evenly distributed on the sliding bearing end face (1), and an axial through groove (5) is formed in the shaft hole (2) of the sliding bearing. The magnetic pump sliding bearing is simple in structure and easy to machine and is identical to a common magnetic pump sliding bearing in installing mode, a steady-flow backflow cavity is formed in the annular backflow groove (3), so that a siding shaft friction pair can be lubricated well, meanwhile the impurity discharging capacity can be improved, and the probability of bearing locking can be reduced.
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, on the end face of the outside of sliding bearing, is combined with thrust bearing, and sliding bearing coordinates formation friction pair with axle sleeve, to rotor, be radial support effect; Sliding bearing and thrust bearing form friction pair, to rotor, have been axial limiting effect.The two pairs of friction pairs are because of without self-lubricating property, therefore need to be lubricated cooling to it with medium, 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 breakage, 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 referring to shown in accompanying drawing 4,5, along center line, to offer radially feed liquor groove a on the end face of the outside of the sliding bearing matching with thrust bearing, this radially feed liquor groove a be directly communicated with the axial pass trough b offering on sliding bearing endoporus, medium is introduced in sliding bearing and is lubricated cooling to sliding bearing and axle sleeve friction pair.
The lead channel structure of offering on above-mentioned sliding bearing is also imperfect, radially feed liquor groove a is directly communicated with the axial pass trough b offering on sliding bearing endoporus, medium enters radially 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 medium, therefore can not be lubricated fully, the port frictional heat of sliding bearing and axle sleeve is higher, when start, easily there is especially burn-out of bearing, even slag is fallen in breakage, and occurs the phenomenon of bearing locking.
Secondly, while containing impurity in medium, impurity enters radially after feed liquor groove a, because sliding bearing is relative with thrust bearing, rotate, impurity is subject to turning effort, although most of trash flow is crossed radially feed liquor groove a, enters axial pass trough b, yet some tiny particle occasionals are made a forcible entry between the friction pair of sliding bearing and thrust bearing, cause friction pair 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, most of via axial pass trough b, flow out, but some impurity are easy to be subject to turning effort from end, to enter in sliding bearing and axle sleeve friction pair and cause bearing, axle sleeve to damage.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, a kind of sliding bearing that offers 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, axle sleeve damage.
Magnetic Drive Pump Sliding Bearing of the present invention, it is characterized in that offering the annular backflow groove 3 being communicated with axis hole 2 on the end face 1 of the sliding bearing A coordinating with thrust bearing, on the axis hole 2 on the sliding bearing end face 1 coordinating with thrust bearing, have annular backflow groove 3, on the end face 1 of sliding bearing, be uniformly distributed and have 2 or the tangent lead channel 4 of a plurality of and annular backflow groove 3, on sliding bearing axis hole 2, offer axial pass trough 5.
The present invention is simple in structure, easily processing, and 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 backflow groove 3, axial pass trough 5 form the runner of carrying lubricant medium, and annular backflow groove 3 forms current stabilization refluxing chamber.Because lead channel 4 is to be that tangent direction is uniform to be offered with annular backflow groove 3 on sliding bearing A end face, lead channel 4 has automatic guide drainage, medium is rotated 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 the stable rotary current of the interior formation of annular backflow groove 3, and make to obtain sufficient medium in annular backflow groove 3, the friction pair port that particularly makes sliding bearing and axle sleeve form is completely infused in annular backflow groove 3 media, 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, be lubricated cooling, whole friction lubricating effect is improved greatly.
While containing impurity in fed sheet of a media, because lead channel 4 has drainage leading role, air flowability is good, and impurity can enter in annular back flash 3 by lead channel 4 smoothly along with medium, follows medium and stablizes revolution, play the crowded effect of buffering, then with medium, enter in axial pass trough 5 and flow out outside sliding bearing A, and be not easy to enter in the friction pair of sliding bearing and thrust bearing, improved impurity removal ability, thereby can not damage friction pair, reduce the occurrence probability of bearing locking.
