The object of the invention is for existing issue, provide the high temperature resistant unit loading type machine envelope of a kind of new type water cooling acid resistant alkali.
The present invention is achieved by the following technical solutions: the high temperature resistant unit loading type machine envelope of a kind of new type water cooling acid resistant alkali, it comprises pump shaft, tetrafluoro bellows is provided with outside pump shaft, be provided with sealing case outside tetrafluoro bellows to be surrounded, sealing case front end is fixed with stationary ring, rotating ring is provided with between tetrafluoro bellows and sealing case, tetrafluoro bellows and rotating ring rotate with pump shaft, multiple spring seat is provided with in tetrafluoro bellows front end, at spring seat built with little spring, rotating ring locking Hough is fixed with in tetrafluoro bellows rear end, little spring rear end and rotating ring are locked Hough and are connected, sealing case rear end engages with sealing box cover, the side of sealing case is provided with cooling water outlet and inlet, at sealing box cover built with water-sealed bearing, multiple O type circle is provided with between sealing box cover and pump shaft.
As further improvement of these options, described stationary ring and rotating ring adopt silicon carbide to make, and described sealing case and sealing box cover are processed by 304 material integral types, can play the effect of acid resistant alkali with tetrafluoro bellows.
As further improvement of these options, described stationary ring has jump ring to be fixed on sealing case front end, thus stationary ring, rotating ring, tetrafluoro bellows and sealing case composition unit loading type machine envelope, in use as integral installation, maintenance or replacing, improve working efficiency, easy-to-operat.
As further improvement of these options, the airtight cavity that described sealing case, sealing box cover, stationary ring, rotating ring and tetrafluoro bellows are formed is cooling water passage, cooling water is at passage Inner eycle, directly rotating ring and stationary ring connecting part temperature can be reduced, simultaneously under the effect of rotating ring, stationary ring and tetrafluoro bellows, cooling water can not enter in pump chamber the work that affects to carry out, and be equiped with water-sealed bearing in sealing box cover, cooling water also can not be revealed.
As further improvement of these options, the end face sprayed wc that described rotating ring connects with stationary ring, can increase flatness and the abrasion resistance on rotating ring surface, is conducive to reducing the friction with stationary ring.
The present invention has the following advantages compared to existing technology: traditional axle sleeve is replaced with tetrafluoro bellows, cooling water cavity is formed with silicon carbide stationary ring, silicon carbide rotating ring, sealing case and sealing box cover, the high temperature that can reduce rotating ring and stationary ring place high temperature and caused by high temperature media under corrosion resistant condition, extends the working life of machine envelope; By by each parts fixed installation composition unit loading type structure, machine envelope is installed convenient, easy maintenance and replacement; When ensureing recirculated cooling water, pump idle running is unaffected, and this machine envelope heatproof can reach about 180 °.
