Abstract
The utility model provides a full cover single -stage cantilever pump that presss from both sides, includes the pump body, the end of intaking, go out water end (W. E. ), impeller, pump shaft, pump cover and machine and seal the gland, it keeps warm to be equipped with on the pump body presss from both sides the cover to be equipped with entry and export, it keeps warm to be equipped with on the pump cover presss from both sides the cover, presss from both sides to sheathe in to be equipped with entry and export, the machine seal and to be equipped with the cavity in the gland and to keep warm and press from both sides the cover, it is equipped with entry and export to keep warm to press from both sides to sheathe in. Let in liquid thermal medium or vapours respectively with keep warm connecting from the entrance, all do not have with pumped (conveying) medium contact or the pumped (conveying) medium department of leaving over and omit comprehensive heat preservation to the pump body, all can not solidify or the crystallization leads to the fact the damage to the pump body because of the medium when guaranteeing that the pump is started shooting at operating condition or after shutting down again, improved the life -span of the pump body, the continuity of assurance pump body work. This pump mainly used carries liquid low temperature or high temperature, neutral or that have corrosive, easy crystallization or easily solidify. When carrying high temperature medium, each presss from both sides cover department and lets in liquid coolant or air conditioning.
Description
One, technical field
The utility model relates to mechanical engineering pump class technical field, specifically a kind of full chuck single-stage cantilever pump.
Two, background technique
In prior art, chemical field conveying chemical medium at home, in order to prevent medium in course of conveying because the requirement of slurries to temperature cannot be met, and make slurries be subject to the impact of temperature and crystallization, thus the pump housing is adopted use thermal-protective material to carry out canoe and be incubated, reduce external temperature to the impact of medium.Because pump housing outer wall adopts thermal-protective material to be wound around, heat insulation effect is poor, makes slurries in course of conveying, easily at the surface crystallization that slurry liquid contacts is crossed, affects the working life of pump, reduces the working efficiency of pump.The thermal-protective material simultaneously wrapped up is shorter for working life, needs periodic replacement, adds maintenance expenses.
Three, summary of the invention
For solving deficiency of the prior art, the purpose of this utility model is to provide a kind of full chuck single-stage cantilever pump, to the comprehensive isothermal holding in position of fed sheet of a media contact in the pump housing.
The technological scheme realizing the purpose of this utility model employing is: this full chuck single-stage cantilever pump comprises the pump housing, feed-water end, waterexit end, impeller, pump shaft, pump cover and machine sealed cover; The outside of the described pump housing is provided with the pump housing insulation jacket forming enclosed cavity with the pump housing, and this insulation jacket is provided with insulation steam inlet and insulation steam (vapor) outlet, the pump housing is also provided with pump housing discharge opeing outlet; Be provided with the pump cover insulation jacket forming closed cavity with pump cover outside described pump cover, pump cover insulation jacket is provided with pump cover insulation steam inlet and pump cover insulation outlet; Be provided with cavity insulation jacket in described machine sealed cover, insulation jacket is provided with insulation steam inlet and insulation steam (vapor) outlet, machine sealed cover is also provided with the flushing hole of machine envelope.
The beneficial effects of the utility model are: owing to being provided with insulation jacket to the pump housing, pump cover and machine sealed cover place respectively; liquid heat medium or hot steam is passed into from thermal insulation joint; to contact with fed sheet of a media or the fed sheet of a media place of leaving over carries out nothing and omits and be incubated comprehensively the pump housing is all; guarantee that pump all can not solidify or crystallization and cause damage to the pump housing because of medium when again starting shooting in working order or after shutting down; improve the life-span of the pump housing, ensure the continuity of pump housing work.
This 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 that easily solidifies.When carrying high temperature media, each chuck place passes into liquid coolant or cold air.
Four, accompanying drawing explanation
Fig. 1 is the utility model full chuck single-stage cantilever pump structure sectional view.
Embodiment
