Abstract
The invention discloses a mechanical seal of an anti-corrosion centrifugal pump, comprising a stationary ring, a movable ring and a stationary ring base. A shaft sleeve is sleeved on a pump spindle. The movable ring is sleeved on the shaft sleeve. The stationary ring is installed on a rear pump cover through the stationary ring base. A spring base is sleeved on the shaft sleeve. The spring base is fixed on the rear pump cover. A pressure spring is arranged between the stationary ring base and the spring base. A cooling water access channel is arranged on the rear pump cover. On the one hand, the temperature of the stationary ring and the movable ring is reduced by the cooling water to improve the sealing effect there-between, on the other hand, the particles from abrasion of the stationary ring and the movable ring are washed by circulation of the cooling water to prevent the particles from accelerating abrasion between the stationary ring and the movable ring and to improve the service lives of the stationary ring and the movable ring. The product is widely applied to the anti-corrosion centrifugal pumps for conveying highly corrosive liquid in the industrial production processes such as petrochemical industry, metallurgy, smelting, electric power, synthetic fibre and food, etc.
Description
Technical field
The present invention relates to relate to a kind of corrosion resisting centrifugal pump, especially a kind of mechanical seal of corrosion resisting centrifugal pump.
Background technique
At present, both at home and abroad in industrial processes such as petrochemical industry, metallurgy, smelting, electric power, synthetic fiber, food in the anti-corrosive pump that generally uses owing to contain solid particle in the corrosive liquids of carrying; The fluid temperature of carrying simultaneously reaches more than 100 ℃ sometimes; Seal arrangement to pump is had higher requirement, in case leakage phenomenon appears in pump, the strongly corrosion liquid of conveying can corrode the parts of pump on the one hand; Greatly reduce the working life of pump, pump is scrapped in serious meeting; The strongly corrosion liquid that leaks on the other hand pollutes the environment, even jeopardizes personal safety.Single mechanical end face seal is generally all adopted in the sealing of existing pump.This single mechanical end face seal is that rotating ring is installed on the pump shaft, and direct and stationary ring seals.But this seal arrangement is because it lacks good cooling and compensation device, and therefore, in the high-speed rotation process of pump, the phase mutual friction between the dynamic and static ring very easily causes the wearing and tearing and the leakage of Sealing.
Summary of the invention
The object of the invention is to provide a kind of mechanical seal of new structure, adopts the mechanical seal of band cooling water, reduces the temperature of dynamic and static ring on the one hand through cooling water, improves sealing effect between the two.
Technological scheme of the present invention is achieved in that
A kind of mechanical seal of corrosion resisting centrifugal pump comprises stationary ring, rotating ring and stationary seat, on pump shaft, is set with axle sleeve; Said moving ring sleeve is contained on the said axle sleeve; Said stationary ring is installed on the rear pump cover through stationary seat, on said axle sleeve, is set with spring seat, and said spring seat is fixed on the said rear pump cover; Between said stationary seat and spring seat, be provided with stage clip, it is characterized in that: described rear pump cover is provided with the cooling water access way.
The adjusting screw is arranged on the said spring seat.
The present invention compared with prior art has following advantage:
1. owing to adopt the band spring assembly, after wearing and tearing appear in phase mutual friction between the dynamic and static ring, regulate compensation, make to be in good sealing state between the dynamic and static ring all the time through the elasticity of spring.
2. the adjusting screw is arranged on spring seat, move axially, make spring remain good state, further improve the working life of mechanical seal through bolt Regulation spring seat.
3. because pump uses in the environment more than 100 ℃, the long-time temperature of back dynamic and static ring of using can raise, and can have a strong impact on its sealing effect like this; Rear pump cover is provided with the cooling water access way for this reason, reduces the temperature of dynamic and static ring on the one hand through cooling water, improves sealing effect between the two; Circulation through cooling water on the other hand; The dynamic and static ring wear particle is washed away, prevent that particle from quickening the wearing and tearing between the dynamic and static ring, improves the working life of dynamic and static ring.

Embodiment
As can be seen from Figure 1, a kind of mechanical seal of corrosion resisting centrifugal pump comprises stationary ring 2, rotating ring 8 and stationary seat 7; On pump shaft 5, be set with axle sleeve 4, said rotating ring 8 is sleeved on the said axle sleeve 4, and said stationary ring 2 is installed on the rear pump cover 1 through stationary seat 7; On said axle sleeve 4, be set with spring seat 6; Said spring seat 6 is fixed on the said rear pump cover 1, between said stationary seat 7 and spring seat 6, is provided with stage clip 3, and described rear pump cover 1 is provided with cooling water access way 9.
The screw 10 of adjusting is arranged on the said spring seat 6.
