Description
Technical field
The present invention relates to mechanical engineering pump class technical field, specifically full chuck single-stage cantilever pump.
Background technology
In the prior art, chemical field conveying chemical medium at home, in order to prevent medium in course of conveying because can not
Meet requirement of the slurries to temperature, and make slurries affected by temperature and crystallize, heat-barrier material is used so as to be used to the pump housing
The mode of being wound is incubated, and reduces influence of the ambient temperature to medium.Because pump housing outer wall is twined using heat-barrier material
Around, heat insulation effect is poor, makes slurries in course of conveying, the surface crystallization easily crossed in slurry liquid contacts, influences the service life of pump,
Reduce the operating efficiency of pump.The heat-barrier material service life wrapped up is shorter, it is necessary to regularly replace simultaneously, adds maintenance cost
With.
The content of the invention
To solve deficiency of the prior art, it is an object of the invention to provide full chuck single-stage cantilever pump, in the pump housing
The comprehensive isothermal holding in position of pumped (conveying) medium contact.
Realizing the technical scheme that the purpose of the present invention uses is：The full chuck single-stage cantilever pump includes the pump housing, water inlet end, gone out
Water end (W.E.), impeller, pump shaft, pump cover and machine sealed cover；The outside of the described pump housing is provided with the pump housing guarantor that closed cavity is formed with the pump housing
Warm chuck, the insulation jacket are provided with insulation steam inlet and insulation steam (vapor) outlet, pump housing discharge opeing outlet are additionally provided with the pump housing；It is described
Pump cover on the outside of be provided with pump cover formed closed cavity pump cover insulation jacket, pump cover insulation jacket be provided with pump cover insulation steam
Entrance and pump cover insulation outlet；Cavity insulation jacket is provided with described machine sealed cover, insulation jacket is provided with insulation steam and entered
Mouthful and insulation steam (vapor) outlet, be additionally provided with machine sealing flushing hole on machine sealed cover.
The beneficial effects of the invention are as follows：Due to respectively to being provided with insulation jacket at the pump housing, pump cover and machine sealed cover, from guarantor
Warm joint is passed through liquid heat medium or vapours, it is all to the pump housing contacted with pumped (conveying) medium or the pumped (conveying) medium place of leaving carry out nothing
Omit insulation comprehensively, it is ensured that will not be because of medium solidification or crystallization and to pump when pump turns back on after working condition or shutdown
Body causes to damage, and improves the life-span of the pump housing, ensures the continuity of pump housing work.
The full chuck single-stage cantilever pump is a kind of specific area and device pump, mainly for delivery of low temperature or high temperature,
Neutral or mordant, easy crystallization or the liquid easily solidified.When conveying high-temperature medium, liquid cooled is passed through at each chuck
Medium or cold air.

Service life.Machine sealing flushing hole 10 is additionally provided with machine sealed cover 12, is inputted from sealflushing at hole in flushing liquor flushing cavity
Medium, it can prevent it from solidifying or crystallizing.Due to respectively to being provided with insulation jacket at the pump housing, pump cover and machine sealed cover, from insulation
Joint is passed through liquid heat medium or vapours, it is all to the pump housing contacted with pumped (conveying) medium or the pumped (conveying) medium place of leaving carry out nothing left
Leakage insulation comprehensively, it is ensured that will not be because of medium solidification or crystallization and to the pump housing when pump turns back on after working condition or shutdown
Cause to damage, improve the life-span of the pump housing, ensure the continuity of pump housing work.
The full chuck single-stage cantilever pump is a kind of specific area and device pump, mainly for delivery of low temperature or high temperature,
Neutral or mordant, easy crystallization or the liquid easily solidified.When conveying high-temperature medium, liquid cooled is passed through at each chuck
Medium or cold air.
