Description
Technical field
The utility model relates to a kind of guide bearing parts, relates in particular to a kind of branched stay tube formula guide bearing parts, belongs to mechanical equipment technical field.
Background technique
Guide bearing parts are one of critical components of large-scale salt pump, mainly play and bear salt pump rotatable parts radial force, stablize the effect of wheel rotation, if salt pump bearing wear is excessive or damage, unit roll bearing swing amplitude then can be caused larger, vibration aggravation, even can there is the faults such as salt pump shutdown, in prior art, because the bearing shell in guide bearing parts is easily worn part, frequent needs are regularly changed, maintenance and inspection, when needing to change, whole pump is generally needed to open, carry out changing and keeping in repair, first this repair and replacement operating time is longer, inefficiency, secondly, because whole pump is opened by needs, in detection Renewal process, easily affect other structure members, secondary is brought to wear and tear, therefore, a kind of new technological scheme of exigence solves the problems of the technologies described above.
Summary of the invention
In order to solve above-mentioned Problems existing, the utility model discloses a kind of vertical branched stay tube formula guide bearing parts, the design of this Whole Equipment is ingenious, and structure is simple, safe and reliable, convenient disassembly, with low cost.
To achieve these goals, the technical solution of the utility model is as follows: a kind of branched stay tube formula guide bearing parts, it is characterized in that, described guide bearing parts comprise pump shaft, the outside of described pump shaft is provided with protective shaft sleeve, the outside of described protective shaft sleeve is provided with bearing shell, and described guide bearing parts also comprise support tube and the guide shaft bearing for supporting whole guide bearing parts.The quantity of described support tube is three, is arranged on uniformly around pump shaft; Whole Technical Design is ingenious, compact structure, three support tubes are provided with in this technological scheme, solve the technical barrier that single tube in prior art exists fused salt shaft seal, fused salt is flow through from multiple support tube, fused salt and axle are kept apart, ensure fused salt leak free danger in high pressure operating mode, avoid high-temperature molten salt simultaneously and transmit temperature along axle, ensure salt pump smooth running, increase substantially the working life of salt pump.
Improve as one of the present utility model, described guide bearing parts also comprise seal ring, and described seal ring is arranged on the inside of protective shaft sleeve, increase its seal action.
Improve as one of the present utility model, described guide shaft bearing comprises supporting component and lower supporting assembly, and described upper supporting component and lower supporting assembly are all set to semicircle, are fastened togather by fastening piece, when dismounting and assembling, very convenient.
Improve as one of the present utility model, described support tube is set to cylindrical body, and soundness is strong.
Improve as one of the present utility model, described protective shaft sleeve is fixed on axle by lock screw, and described locking member comprises lock bolt and locking nut, guide shaft bearing is fixed on support tube.
Relative to prior art, advantage of the present utility model is as follows: 1) overall construction design is ingenious, compact structure, and detachable maintaining is convenient, and working efficiency improves greatly; 2) guide bearing parts are set to a point half formula structure by this technological scheme, when needs to be changed bearing shell or keeped in repair, only need component home to open, do not need to dismantle whole salt pump, substantially increase working efficiency; 3) be full of fused salt in the cavity in this technological scheme, carry out lubricating bearings by fused salt, increase substantially the working life of bearing shell, ensure the stationarity of salt pump running simultaneously; 4) three support tubes are provided with in this technological scheme, solve the technical barrier that single tube in prior art exists fused salt shaft seal, fused salt is flow through from multiple support tube, fused salt and axle are kept apart, ensure fused salt leak free danger in high pressure operating mode, avoid high-temperature molten salt simultaneously and transmit temperature along axle, ensure salt pump smooth running, increase substantially the working life of salt pump; 5) this technological scheme cost is lower, is convenient to apply on a large scale.
