Description
Technical field
The utility model belongs to a kind of pump, specifically is a kind of slag stock pump.
Background technique
Along with the fast development of industries such as mine, iron and steel, coal, electric power, chemical industry, raw materials that it is involved and waste material all will lean on the slag stock pump to carry out the liquid formula and carry, and use amount is increasing, and product requirement is also more and more higher.Slag be pump head, carriage, motor and base four macrostructures composition with using in the pump series more widely, and the structural design in the pump head directly has influence on the working efficiency and the working life of pump, and sealing problem also is need progressively improved key issue.
The model utility content
The purpose of this utility model provides a kind of slag stock pump, has advantages such as simple in structure, installing/dismounting maintenance convenience, good seal performance, can effectively prevent to leak, and the life-span and the efficient of raising pump reduce production costs.
The technical solution of the utility model is as follows:
The slag stock pump, include carriage, pump shaft, the pump housing, pump cover, outlet, impeller, it is characterized in that described impeller is fixed on the pump shaft front end that passes pump housing center by scyewed joint, apron plate is arranged respectively before and after the impeller, back backplate, apron plate, back backplate has upper jacket up and down respectively, lower jacket, constitute the cavity of a sealing, apron plate, back backplate and upper jacket, the lower jacket contact outside has back blade respectively, cavity has the pump housing and pump cover before and after the outside, and impeller tip has outlet, and outlet is passed from pump cover, adopt seal ring one sealing, adopt accessory lobes wheel shaft envelope and packing shaft seal between the pump housing and pump shaft, between sub-propeller and pump shaft bearing support is arranged, bearing is arranged in the bearing support, axle sleeve is arranged on the pump shaft, there is bearing gland the bearing support outer end, in seal ring two is arranged, pump shaft is installed on the carriage.
Described sub-propeller non-working surface one side is provided with the transition inclined-plane, apron plate from the axle center outside axle thickening gradually, back backplate from the axle center outside axle by attenuation.
Described outlet can be rotated eight different angles and install and use by 45 ° of intervals.
The transmission position of described bearing is an opposite opened, and bearing is heavy single-row tapered roller bearing, uses thin oil grease lubrication.
The utility model is the double pump shell structure, and the gradually thick and gradually thin design of front and back backplate can strengthen wear resistance, and the forward and backward backplate of impeller has back blade to leak to reduce, and can improve the life-span and the efficient of pump.The axle envelope adopts accessory lobes wheel shaft envelope and packing shaft seal, and accessory lobes wheel shaft envelope has advantages such as not diluting ore pulp, sealing long service life, good sealing effect, and packing seal structure is simple, and is easy to maintenance.Can adopt direct driving, bearing block assembly structure intensity height, the pump shaft diameter is big, good rigidly, cantilever is short, can crooked and vibration under abominable operating mode.Bearing is selected heavy single-row tapered roller bearing for use, can bearing pump axially and radial load.There is bearing gland at the bearing support two ends, in seal ring is arranged, can prevent effectively that ore pulp from entering and the leaking of lubricating grease, and guarantees the bearing safe operation.Use thin oil grease lubrication, can reduce axle temperature.Overall structure 100% is detachable, and it is convenient to install, overhaul.
