Abstract
The utility model relates to a kind of high speed centrifugal pump, comprise the pump housing and pump cover, the described pump housing is fixedly mounted on pump cover, in the pump housing, there is inducer, lagging is provided with outside the described pump housing, there is between described lagging and the pump housing insulation holding space, described lagging is provided with import and outlet, described import communicates with outlet, import and outlet all communicate with insulation holding space, therefore only steam or hot water need be connected in the import of lagging, steam or hot water will enter insulation holding space, go out from the outlet of lagging again and form circulation, the pump housing is remained in certain temperature range always, thus the medium in the pump housing can not be subject to extraneous thermal effect, together with medium and inducer can not freeze with impeller, even if high speed centrifugal pump is shut down for a long time, when starting shooting, inducer and impeller also can not damage again, the inducer that avoiding needs repairing more renews and impeller, cost of production is reduced greatly.
Description
Technical field
The utility model relates to a kind of high speed centrifugal pump, particularly relates to a kind of insulation high speed centrifugal pump.
Background technique
Existing high speed centrifugal pump comprises the pump housing and pump cover, the described pump housing is fixedly mounted on pump cover, in the pump housing, there is inducer, inducer is connected with impeller, this high speed centrifugal pump has the following disadvantages, the pump housing does not have heat insulation function, when using under the environment that temperature is lower, if high speed centrifugal pump is shut down for a long time, medium in the pump housing can be frozen in crystallization, here medium can be water, oil or other liquid, together with medium and inducer freeze with impeller, when high speed centrifugal pump is started shooting again, cause inducer and impeller failure, need repairing the inducer and impeller that more renew, the process of maintain and replace inducer and impeller is complicated, difficulty is high, cost of production is improved greatly.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of high speed centrifugal pump having heat insulation function, inducer and impeller and be not easily frozen in.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of high speed centrifugal pump, comprise the pump housing and pump cover, the described pump housing is fixedly mounted on pump cover, in the pump housing, there is inducer, lagging is provided with outside the described pump housing, there is between described lagging and the pump housing insulation holding space, described lagging is provided with import and outlet, described import communicates with outlet, import and outlet all communicate with insulation holding space, the pump housing comprises the first flange plate, second flange plate and pipeline, described first flange plate is connected by pipeline with between the second flange plate, described lagging has the first joint and the second joint, first joint and first flange plate of described lagging are welded and fixed, second joint and second flange plate of described lagging are welded and fixed.
The beneficial effect of a kind of high speed centrifugal pump that the utility model provides is: owing to being provided with lagging outside the described pump housing, there is between described lagging and the pump housing insulation holding space, described lagging is provided with import and outlet, described import communicates with outlet, import and outlet all communicate with insulation holding space, and make the first joint and the first flange plate by being welded and fixed, second joint is connected more firm with the second flange plate, sealing effect is better, steam or hot water can not spill from the joint between the first joint and the first flange plate or spill from the joint between the second joint and the second flange plate, make better heat preservation, therefore only steam or hot water need be connected in the import of lagging, steam or hot water will enter insulation holding space, go out from the outlet of lagging again and form circulation, make the pump housing remain in certain temperature range always, thus the medium in the pump housing can not be subject to extraneous thermal effect, together with medium and inducer can not freeze with impeller, even if high speed centrifugal pump is shut down for a long time, when starting shooting, inducer and impeller also can not damage again, the inducer that avoiding needs repairing more renews and impeller, cost of production is reduced greatly.
