Abstract
The plywood chemical pump is made up of impeller, rotor ring, stator ring and spring. Rotor is in the flute formed by the back-end of impeller. The outer circularity of the back-end of impeller fix stationary seat, and stator is in the lumen of it. Spring seat is in the back cavity formed by stationary seat, and its front-end is inserted in the stationary seat's inner bore. Spring is in the back cavity of spring seat. At the back of spring fixed framework oil seal. End closure join seal box together, and locked strictly by countercheck nut so as to pressurize shafting bearing. The invention's structure is briefness and compact, the design is rational and the manufacture is convenient. It is the same with more complicated working situation.
Description
Technical field: the present invention relates to a kind of pump, particularly relate to a kind of Fished chemical industry pump.This pump is widely used in temperature and is lower than 150 ℃, contains acid, alkali, the salt of any concentration of certain solid particle, the conveying of media such as Strong oxygenant, organic solvent.More be applicable to the use of pickling line, acid regeneration, neutralization station and the sour degreasing line of metallurgy industry.
Technical background: at present, this class pump of domestic use, its seal arrangement all is to be provided with spring, rotating ring, stationary ring in the impeller back, and spring, rotating ring, stationary ring move with impeller.Easy to wear, the heating of spring, rotating ring, stationary ring like this, leak, shortened the working life of part, improved cost, increased operator's work Strong degree.Be a problem that urgency is to be solved, more and more be subject to people's attention.
Summary of the invention: the present invention will provide Fished chemical industry pump exactly, and it can solve the problem that at present domestic this class pump exists well.The object of the present invention is achieved like this, Fished chemical industry pump, be by pump housing shell, the pump housing, impeller, pump cover, stationary seat, spring seat, sealed case, rotating ring, stationary ring, spring, outside framework oil seal, the retaining nut is formed, it is characterized in that: in the front end inner chamber of pump housing shell, be provided with the pump housing and pump cover, in the inner chamber of the rear end of pump housing shell, be provided with main shaft, the top of main shaft is provided with impeller, impeller is arranged in the inner chamber of the pump housing and pump cover formation, rotating ring is arranged in the groove of impeller rear end formation, pump cover and sealed case are by screw attachment, device has stationary seat on the cylindrical of impeller rear end, and stationary seat front end inner chamber is provided with stationary ring, and spring seat is arranged in the back cavity of stationary seat formation, the spring seat front end is inserted in the endoporus of stationary seat, controlling the axial motion of stationary ring, the spring seat back cavity installs spring, and outside framework oil seal is equipped with in the back of spring, outside framework oil seal is arranged in the groove of sealed case formation, end cap connects with sealed case, by retaining nut check, is controlling the axial motion of impeller; Rotating ring, refining the forming of stationary ring employing sintered silicon carbon material wear-resisting, corrosion resistant.The present invention is simple and compact for structure, reasonable in design, part is not easy to wear, can reach to increase the service life, and saves cost, alleviates the purpose of operator's work Strong degree.
Description of drawings: Fig. 1 is a structural representation of the present invention.
Fig. 2 is the local enlarged diagram of sealing part.
1. pump housing shell, the 2. pump housing, 3. impeller, 4. pump cover, 5. stationary seat, 6. spring seat, 7. sealed case, 8. rotating ring, 9. stationary ring, 10. spring, 11. outside framework oil seals, 12. retaining nuts.
Embodiment: the invention will be further described below in conjunction with accompanying drawing.
In the drawings, Fished chemical industry pump is by pump housing shell 1, the pump housing 2, impeller 3, pump cover 4, stationary seat 5, spring seat 6, sealed case 7, rotating ring 8, stationary ring 9, spring 10, outside framework oil seal 11, retaining nut 12 is formed, it is characterized in that: in the front end inner chamber of pump housing shell 1, be provided with the pump housing 2 and pump cover 4, in the inner chamber of the rear end of pump housing shell 1, be provided with main shaft, the top of main shaft is provided with impeller 3, impeller 3 is arranged in the inner chamber of the pump housing 2 and pump cover 4 formation, rotating ring 8 is arranged in the groove of impeller rear end formation, pump cover 4 and sealed case 7 are by Bolt Connection, the cylindrical of impeller 3 rear ends is provided with stationary seat 5, be provided with stationary ring 9 in the inner chamber of stationary seat 5 front ends, spring seat 6 is arranged in the back cavity of stationary seat 5 formation, spring seat 6 front ends are inserted in the endoporus of stationary seat 5, controlling the axial motion of stationary ring 9, spring seat 6 back cavities are provided with spring 10, the back of spring 10 is provided with outside framework oil seal 11, outside framework oil seal 11 is arranged in the groove of sealed case formation, end cap connects with sealed case 7, by 12 lockings of retaining nut, controlling the axial motion of impeller; Rotating ring 8, stationary ring 9 adopt refining the forming of sintered silicon carbon material wear-resisting, corrosion resistant.During concrete enforcement, when the main shaft impeller is rotated, because rotating ring is arranged in the groove of impeller rear end formation, so drive the rotating ring rotation.Because impeller rotation back medium axially sucks, radially ejection, there be the gap of a little medium between impeller and pump cover to lubricate and cooling off rotating ring and stationary ring, because stationary ring and spring install respectively in stationary seat and spring seat, they do not rotate with impeller, also just reduce heating and wearing and tearing, guaranteed sealability equally.In addition, sealed case below is provided with the high-voltage tube road junction, and washing solution enters from the below, is used for the cleaning and the cooling of mechanical sealing system through spring, stationary ring, rotating ring, has improved working life greatly, has saved cost.
