According the invention, the problems that when the bearing is replaced, a user need to demount the bearing body, and after the bearing and the shaft are burnt, the user needs to dismantle the whole centrifugal pump to replace the bearing are solved; the bearing is convenient and fast to replace; the phenomenon that the shaft is scratched when the bearing is replaced is reduced, and thus the service life of the shaft is prolonged.
Description
Technical field
The present invention relates to centrifugal pump technical field, particularly a kind of centrifugal pump of detachable type.
Background technique
At present, the pump using in industry-by-industry, its pump bearing body is generally comprised of locking nut, bearing gland, bearing, bearing support and axle.Fit dimension between bearing and axle is interference fit, when locking nut is by after bearing locking, between locking nut and bearing inner race end face, has stiction, and due to the effect of stiction, axle drives locking nut and bearing inner race to rotate together.There is following problem in this existing bearing block of centrifugal pump: bearing is that easily damaged parts needs periodic replacement, because the fit dimension between bearing and axle is interference or transition fit, coordinate tighter, during frequent dismounting bearing, be easy to damage axle, axle be belong to pump one of vital part, after axle dismounts badly, the value of changing axle is higher, and very complicated time-consuming during dismounting; When if bearing damage generation bearing inner race and axle are burnt to death, whole pump need to be dismantled and could be changed bearing, dismounting is complicated, and pump shaft is scrapped damage.
Summary of the invention
Above-mentioned defect and problem for prior art, the object of the invention is to provide a kind of detachable type centrifugal pump, solve to change the bearing bearing support problem of need to dismantling, bearing and axle need to tear open the problem that whole pump is changed bearing difficulty after burning to death, make the replacing of bearing more convenient, reduce the problem that causes scratch while changing bearing to axle, increased the working life of axle.
In order to achieve the above object, the present invention realizes by the following technical solutions:
A kind of detachable type centrifugal pump, comprise bearing part, pump case and rotor part, described bearing part is connected with rotor part, described pump case and bearing part, rotor part connects, described bearing part comprises bearing gland, bearer ring, bearing housing, bearing, bearing support, axle, bearing nut, described bearing is connected in interference mode with bearing housing, described bearing housing is connected in gap mode with axle, described bearing is connected with bearing support, described bearer ring is connected with bearing housing, described bearing gland is connected with bearing support, after being connected with bearing housing, described bearing is connected with bearing support inner ring, described bearer ring is connected with axle, described bearing nut and axle, bearer ring connects.
Further technological scheme, described bearer ring is inserted and is connected by interleaved mode with bearing housing.
Further technological scheme, described bearer ring links into an integrated entity by key and axle.
Further technological scheme, described bearing gland connects as one by attachment bolt and bearing support.
Further technological scheme, between described bearer ring and axle, all connect with transient mode between bearing housing and axle.
Further technological scheme, on the inner ring of described bearer ring, Baltimore groove is set, anchor ring one end of bearer ring arranges groove, and the bottom, outer ring of described bearing housing arranges ring-shaped step, the inner ring top of bearing housing arranges projection, and the projection of described bearing housing is connected with the anchor ring groove of bearer ring.
The invention provides the portable bearing of tearing formula centrifugal pump open is Spielpassung with coordinating of axle, dismounting is very convenient, the bolt that does not need to dismantle on bearing support and bearing support just can be pulled down bearing, during assembling, do not need heating yet or just knock and can easily pack into, and dismounting repeatedly can not produce and damage the axle of pump, even if there is sintering in the inner ring of bearing and axle, during dismounting, can not injure axle yet, improved the working life of centrifugal pump, in addition, the spare parts cost that the present invention needs when dismounting is few, and maintenance cost is low.
