Abstract
The utility model belongs to the technical field of fluid transfer machinery, and particularly relates to a cantilever type concentrated sulfuric acid submerged pump. The technical scheme of the utility model is as follows: the inner bore wall of a bush is provided with axial through grooves; and a set of roller bearing is fixed in the lower opening of a bearing sleeve under an angular contact ball bearing, and is matched with a pump shaft. The novel cantilever type concentrated sulfuric acid submerged pump is simple in structure, the design is reasonable, the universality is higher, the phenomenon that the bush and a shaft sleeve are locked is reduced, the bearing capability can be enhanced, so that a rotor can be more reasonably stressed to operate stably, and thereby the service life of the pump is prolonged.
Description
Technical field
The utility model belongs to the fluid conveying machine technical field, is specifically related to a kind of cantilever type concentrated sulphuric scid Under Water Pumps.
Background technique
At present, traditional concentrated sulphuric scid Under Water Pumps conveying be mixed with solid particle polluter concentrated sulphuric scid medium operating mode in operation following problem can appear: owing to only adopted Spielpassung between the lining of liquid properties of journal bearing lubricated part and the axle sleeve, though the nearly 1mm in monolateral gap, but impurity still enters between axle, the lining easily, cause lining and axle sleeve locking, thereby influenced the operation of whole pump; What put in order the bearing support partial design of pump on liquid is a cover rolling bearing supporting, under above-mentioned operating conditions, pump shaft can't keep enough rigidity to bear the radial load of this moment and two-way thrust load, and produce vibration in the feasible whole pump operation process, thereby shortened the working life of whole pump.Therefore, at above two problems, innovation and architecture advances have been carried out on original pump structure basis.
Summary of the invention
The purpose of this utility model provides a kind of axial suction subdivision cantilever type submerged centrifugal pump radially that contains small amount of solid particle concentrated sulphuric scid medium that is applied to carry, and it is simple in structure, and is reasonable in design, and the generalization degree is higher, can prolong the working life of pump.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions.
Inner hole wall at lining is provided with groove vertically; The lower opening of the bearing support sleeve pipe below angular contact ball bearing is fixed a secondary roller bearing, and this roller bearing cooperates with pump shaft.
Groove on the described lining inner hole wall is arc groove, and the arc groove radius is 6～8mm; The roller bearing that the under shed of bearing support sleeve pipe is adorned is roller bearing.
The beneficial effects of the utility model are: compare with pump structure under the traditional concentrated sulfuric acid solution, when conveying contains the concentrated sulphuric scid medium of impurity, but impurity pass through from the arc groove of lining, thereby reduce the phenomenon of lining and axle sleeve locking; In bearing support part except using a pair of angular contact ball bearing, increase a roller bearing in addition, realize the rigid design of duplex bearing supported axle, increased bearing capacity, make rotor stressed more reasonable and can operate steadily, just can guarantee the continuous long-time running of whole pump, reduce operating cost, prolong the working life of pump.
