Abstract

The special plain bearing housing of low temperature magnetic drive pump, comprises plain bearing housing and spring expanding sleeve; On sliding bearing, be provided with plain bearing housing, plain bearing housing and the body of sliding bearing are provided with spring expanding sleeve between radially, and screw connects with the body of sliding bearing through plain bearing housing end face. Coordinating between plain bearing housing internal diameter and sliding bearing external diameter is interference fits, in spring expanding sleeve two ends, electrical path length is that coordinating between L1 and plain bearing housing external diameter is interference fit, the outer electrical path length of spring expanding sleeve is that coordinating between L2 place and the body of sliding bearing is interference fits, and the radially thin-walled of spring expanding sleeve is thick is B. The present invention is simple in structure, and installation is changed convenient and swift, has interchangeability, can greatly reduce quantity in stock and the production cost of accessory. Can under different operating temperatures, use, the medium that particularly suitable delivery temperature is extremely low, solved because of low temperature cold compression deformation amount inconsistent, and produce axle sleeve and the locking of sliding bearing part, turn problem motionless or that damage rupture cannot turn round, greatly improved the service life of equipment.

Description

The special plain bearing housing of low temperature magnetic drive pump
Technical field: the present invention relates to the special plain bearing housing of a kind of low temperature magnetic drive pump.
Background technology: at present magnetic force pump structure is all that to carry normal temperature medium be design basis, if the temperature of pumped (conveying) mediumSpend very lowly, sometimes reach-180 DEG C of left and right, just can not guarantee the normal operation of pump. Due to the low temperature difference of pumped (conveying) medium, slidingIn the process of manufacture of dynamic bearing body and plain bearing housing, it is different that its fit clearance requires, such machining accuracyBe difficult to control, must accurately measure the actual work temperature of pumped (conveying) medium, accurately calculate shrinkage according to the different material of useDeflection, and this class part cannot exchange as general part, assemble, while being transported to part, be easy to send out wrong and affect pump normallyRunning; If adopt same fit dimension or routinely part processing guarantee interchangeability, the body of sliding bearing and sliding bearing when operationThe shrinkage deflection of seat is inconsistent, causes axle sleeve and sliding bearing part to have locking to turn motionless or damage rupture and cannot turn round existingResemble, pump can not be run well, affected the service life of pump, more serious impact the normal production of chemical enterprise.
Summary of the invention: object of the present invention will provide a kind of low temperature magnetic drive pump special plain bearing housing exactly, it can be fineGround overcomes the existing defect of above existing product, guarantees the running that magnetic drive pump can be reliable and stable under utmost point low-temperature condition. ThisThe object of invention is achieved in that the special plain bearing housing of low temperature magnetic drive pump, comprises plain bearing housing and spring expanding sleeve, its spyLevy and be: on sliding bearing, be provided with plain bearing housing, it is swollen that plain bearing housing and the body of sliding bearing are provided with spring between radiallyCover, screw connects with the body of sliding bearing through plain bearing housing end face. Described plain bearing housing internal diameter and sliding bearing external diameterBetween cooperation be interference fits, in spring expanding sleeve two ends, electrical path length is that coordinating between L1 and plain bearing housing external diameter is interferenceCoordinate, the outer electrical path length of spring expanding sleeve is that coordinating between L2 place and the body of sliding bearing is interference fits, and spring expanding sleeve radiallyThin-walled is thick is B; Described length L 1, L2 change with the size of sliding bearing axial length dimension; The thick B of described thin-walled withThe size of sliding bearing internal diameter size and changing. The present invention is simple in structure, and installation is changed convenient and swift, has interchangeability, can be largeLarge quantity in stock and the production cost that reduces accessory. Can under different operating temperatures, use, particularly suitable delivery temperature is extremely lowMedium, solved because of low temperature cold compression deformation amount inconsistent, and produce axle sleeve and the locking of sliding bearing part, turn motionless or damageThe bad problem of breaking and cannot turn round, the service life of greatly having improved equipment.
Brief description of the drawings: Fig. 1 is structural representation of the present invention;
Fig. 2 is spring expanding sleeve structural representation of the present invention;
1. plain bearing housing, 2. spring expanding sleeve, 3 the body of sliding bearing, 4. sliding bearing.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the invention will be further described:
In the drawings, the special plain bearing housing of low temperature magnetic drive pump, comprises plain bearing housing 1 and spring expanding sleeve 2, and its feature existsIn: on sliding bearing 4, be provided with plain bearing housing 1, it is swollen that plain bearing housing 1 and the body of sliding bearing 3 are provided with spring between radiallyCover 2, screw connects with the body of sliding bearing 3 through plain bearing housing 1 end face. Described plain bearing housing 1 internal diameter and sliding bearing 4Cooperation between external diameter is interference fits, and in spring expanding sleeve 2 two ends, electrical path length is coordinating between L1 and plain bearing housing 1 external diameterFor interference fit, the outer electrical path length of spring expanding sleeve 2 is that coordinating between L2 place and the body of sliding bearing 3 is interference fits, and spring is swollenCover 2 radially thin-walled is thick is B; Described length L 1, L2 change with the size of sliding bearing 4 axial length dimension; DescribedThe thick B of thin-walled changes with the size of sliding bearing 4 internal diameter sizes. When concrete enforcement, described plain bearing housing 1 internal diameter and slipWhen the matching design of bearing outside diameter, be the processing of interference fits dimensional tolerance, spring expanding sleeve 2 two ends internal diameters are designed to certain lengthAdopt interference fit processing with the external diameter of plain bearing housing 1, assemble and form one by heating, in spring expanding sleeve 2 external diametersBetween section certain length is set and the body of sliding bearing 3 internal diameters are processed by interference fits dimensional tolerance; Described spring expanding sleeve radiallyWall thickness design comparison is thin. In the time that magnetic drive pump is worked in the very low temperature of pumped (conveying) medium, the body of sliding bearing 3 and sliding bearing 4 because ofShrinkage coefficient is inconsistent, and the different distortion amount producing can be born solution by the spring expanding sleeve 2 arranging, and does not affect cunningDesign fit dimension and the service life of moving axis bearing 1 and the body of sliding bearing 3, thus guarantee the operation of low temperature lower magnetic force pump.
