Abstract
The utility model discloses the canned motorpump of a kind of Circulation pipe with filter, be provided with canned motorpump and export the Circulation pipe be connected with shield electric machine rear end cover, and Circulation pipe is divided into two pipelines by canned motorpump outlet end, article two, pipeline is all provided with filter, be respectively arranged with a valve in the front side of filter and rear side, between filter and rear side valve, pipeline be provided with pressure gauge; Article two, pipeline is merged into a pipeline in rear side valve rear end pipeline, and is finally connected with shield electric machine rear end cover; During work, article one, the valve closing on pipeline, valve open on another pipeline, cooling circulation liquid enters into motor cavity from that pipeline opened after the filter of correspondence, when filter rear end pressure changes decline, illustrates that filter has stopping state, close valve before and after this pipe line filter, be switched to another pipeline, the filter of cutting out on pipeline cleans, ensure that canned motorpump continuous and steady operation.
Description
Technical field
The utility model relates to canned motorpump, on Circulation pipe, be particularly provided with the canned motorpump of filter.
Background technique
Canned motorpump bearing used is all adopt sliding bearing, carries out cooling and lubricating with fed sheet of a media to bearing, must clean free from admixture so be used for carrying out the medium of cooling and lubricating to bearing.In new system, because the impurity such as the welding slag in pipeline are difficult to clean out, when turn on pump runs, impurity is easy to enter in pump chamber, reaches the bearing in shield electric machine chamber by Circulation pipe, causes damage to bearing.In addition, when conveying has the medium of polymerization property, if temperature is not controlled well, fed sheet of a media will produce polymerization in various degree, and polymer enters into pivot friction face, will cause damage to bearing.
For the problems referred to above, a kind of Circulation pipe of research and design is with the canned motorpump of filter, and it is very necessary for solving existing issue.
Summary of the invention
The utility model, for above-mentioned technical problem, proposes the canned motorpump of a kind of Circulation pipe with filter.
For reaching above object, be achieved through the following technical solutions:
A kind of Circulation pipe is with the canned motorpump of filter, be provided with canned motorpump and export the Circulation pipe be connected with shield electric machine rear end cover, and Circulation pipe is divided into two pipelines by canned motorpump outlet end, article one, pipeline is provided with filter I, be respectively arranged with valve I and valve II in the front side of filter I and rear side, between filter I and valve II, pipeline be provided with pressure gauge I;
Another pipeline installing has filter II, in the front side of filter II with rear side is non-is not provided with valve III and valve IV, between filter II and valve IV, pipeline is provided with pressure gauge II;
Article two, pipeline is merged into a pipeline in valve II and valve IV rear end pipeline, and is finally connected with shield electric machine rear end cover;
Adopt the utility model of technique scheme, during work, article one, all valve closings on pipeline, all valve opens on another pipeline, cooling circulation liquid enters into motor cavity from that pipeline opened after the filter of correspondence, cooling and lubricating is carried out to bearing, when filter rear end pressure changes decline, illustrate that filter has stopping state, close valve before and after this pipe line filter, be switched to another pipeline, the filter of cutting out on pipeline cleans, article two, pipeline can be changed mutually, and then ensure that canned motorpump continuous and steady operation.
Note: for middle indication " front " be canned motorpump outlet direction, place, " afterwards " namely with " front " opposite direction.
The utility model compared with prior art concrete advantage is: when canned motorpump fed sheet of a media contains microimpurity or fed sheet of a media has polymerization situation, can guard shield pump sliding bearing effectively, and extend the working life of bearing, canned motorpump runs more safe and reliable.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to technological means of the present utility model can be better understood, and can be implemented according to the content of specification, and can become apparent to allow above and other object of the present utility model, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
The utility model is totally 2 width accompanying drawings, wherein:
Fig. 1 is side-looking structural representation of the present utility model.
Fig. 2 is plan structure schematic diagram of the present utility model.
In figure: 1, valve I, 2, filter I, 3, pressure gauge I, 4, valve II, 5, valve III, 6, filter II, 7, pressure gauge II, 8, valve IV.
Embodiment
A kind of Circulation pipe is as depicted in figs. 1 and 2 with the canned motorpump of filter, be provided with canned motorpump and export the Circulation pipe be connected with shield electric machine rear end cover, and Circulation pipe is divided into two pipelines by canned motorpump outlet end, article one, pipeline is provided with filter I 2, be respectively arranged with valve I 1 and valve II 4 in the front side of filter I 2 and rear side, between filter I 2 and valve II 4, pipeline be provided with pressure gauge I 3;
Another pipeline installing has filter II 6, in the front side of filter II 6 with rear side is non-is not provided with valve III 5 and valve IV 8, between filter II 6 and valve IV 8, pipeline is provided with pressure gauge II 7;
Article two, pipeline is merged into a pipeline in valve II 4 and valve IV 8 rear end pipeline, and is finally connected with shield electric machine rear end cover;
Adopt the utility model of technique scheme, during work, article one, all valve closings on pipeline, all valve opens on another pipeline, cooling circulation liquid enters into motor cavity from that pipeline opened after the filter of correspondence, cooling and lubricating is carried out to bearing, when filter rear end pressure changes decline, illustrate that filter has stopping state, close valve before and after this pipe line filter, be switched to another pipeline, the filter of cutting out on pipeline cleans, article two, pipeline can be changed mutually, and then ensure that canned motorpump continuous and steady operation.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art are not departing within the scope of technical solutions of the utility model, when the technology contents that appeal can be utilized to disclose is made a little change or is modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
