Abstract
The utility model belongs to the technical field of the fluid conveyor tool, concretely relates to desulfurization circulating pump with adjustable sealed clearance is applicable to the transport of desulfurization system circulation thick liquid in the trades such as oil plant, thermal power plant, sulphur bonderizing worker, steel plant. The improvement of this device does, and the drive shaft of pump supports the structure that adopts bearing box and bearing box, disposes adjusting bolt on the back bearing cover of bearing box, and the adjusting bolt tip supports tightly at the bearing box terminal surface, the sealed simple structure for piston movive seal knot of the antifriction plate and the pump body, nevertheless the design is more reasonable, reliably, can carry out clearance adjustment according to the abrasion condition of pump at any time, compares with traditional chemical pump, and the universalization degree of pump is high, has solved casting, processing, assembly, maintenance difficulty scheduling problem, and it is reliable and stable to make whole pump move, and the life of pump improves the cost is reduced.
Description
Technical field
This utility model belongs to fluid conveying machine technical field and in particular to a kind of adjustable desulphurization circulating of seal clearance
Pump is it is adaptable to the industry Dual alkali such as oil plant, thermal power plant, sulfur phosphorous chemical industry, steel plant, magnesium processes, limestone-gypsum, ammonia process, phosphorus ammonium
The conveying of the desulphurization system loop slurry of the Wet Flue Gas Desulfurization Technologies such as fertile method, seawater method；Conveying solid substance mass concentration is not more than
30%, chlorine ion concentration reaches various acid, neutral, the alkaline burn into abrasion slurry medium of 20000～80000ppm.
Background technology
At present, in the industries such as oil plant, thermal power plant, sulfur phosphorous chemical industry, steel plant, combustion system discharges the SO in flue gas2,
Severe contamination is caused to air.And this station pump is generally traditional one step single sucking chemical pump, using a period of time corrosion mill
After erosion, gap increase between wearing plate meeting in front and back and impeller leads to efficiency to decline, and increases operating cost.
Therefore according to the problem in above practical application, need a kind of adjustable desulphurization circulating of seal clearance of new structure
Pump.
Content of the invention
This utility model purpose is to provide one kind to be used for high wear resistance, corrosion-resistant, acid and alkali-resistance station, pumps with solid
Granule, diluted acid, liquid caustic soda, the desulfuration recycle pump of the medium such as corrosive ore pulp, the impeller of this pump is adjustable with wear-resisting sheet separation in front and back, turns
Subassembly can be adjusted axially, thus the adjustable gap increasing because of abrasion, make seal clearance reduce to reduce leakage, improve pump
Efficiency, it is ensured that pump runs in efficient state, is increased economic efficiency.
Realizing the technical scheme that this utility model above-mentioned purpose takes is：
1. the drive shaft of pump supports the structure using bearing housing with bearing box, configuration adjustment on the rear bearing gland of bearing box
Bolt, regulating bolt end is pushed against bearing box end face.After the completion of assembling, tightening connecting bolt makes bearing box paste with bearing housing
Tightly, then unclamp connecting bolt, adjust the gap between bearing housing and bearing box with regulating bolt and check gap with clearance gauge,
Connecting bolt is being tightened it is achieved that the rotor portion of pump can be adjusted axially after clearance control is good.
2. front wearing plate and the pump housing improve through structure, and wearing plate is sealed into piston movable sealing structure with the pump housing, i.e. the pump housing
Upper configuration adjustment bolt, regulating bolt end is pushed against the end face of front wearing plate.After the completion of assembling, tighten connecting bolt make front resistance to
Nog plate is adjacent to the pump housing, then unclamps connecting bolt, and the gap being adjusted with regulating bolt between front wearing plate and the pump housing is used in combination
Clearance gauge checks gap, is tightening connecting bolt after clearance control is good.If unit has been mounted on pipeline, can be according to regulation
Bolt be screwed into depth to control the gap between the pump housing and front wearing plate（As：M16 regular screw threads pitch often rotates for 2mm
Before one week, wearing plate and the gap of the pump housing increase 2mm）.
When the abrasion of pump burn into seriously leads to efficiency to decline, without changing the pump housing, pump cover, impeller, wearing plate etc., only need
Connecting bolt at wearing plate and bearing box before adjustment and regulating bolt are so that it may so that gap between impeller and forward and backward wearing plate
Reduce, extend whole pump service life, reduce cost.
The beneficial effects of the utility model are：The structure of this clearance adjustment mechanism is simple, but design is more reasonable, reliable,
At any time gap adjustment can be carried out according to the abrasion situation of pump, compared with traditional chemical pump, the generalization degree of pump is high, solves casting
Make, process, assembling, maintenance difficult the problems such as, make whole pump operation reliable and stable, the service life of pump improves, and reduces cost.
