Abstract

The utility model relates to a horizontal type leak-free desander pump which performs improvement to the pump structure of mortar and ore pulp type medium; the defect of leakage of the mechanical sealing pump is overcome; the horizontal type leak-free desander pump is characterized in that the horizontal type leak-free desander pump comprises a pump cover, a pump body, an impeller nut, an impeller, a partition board, an auxiliary impeller, a packing box, a muddy packing material, a packing gland, an axle, a bearing, a bracket, a bearing gland and a shaft coupling; the bearing and the bearing gland are arranged on the axle, the packing gland is arranged on the axle, the packing box is arranged on the axle, the axle is arranged on the bracket, the shaft coupling is arranged at the upper end of the axle, the auxiliary impeller is arranged on the axle and fixed through a key, the partition board is arranged on the auxiliary impeller, the impeller is arranged on the axle and fixed through a key and the impeller nut, the pump body is fixedly connected with the bracket, and the pump cover is arranged at the lower opening of the pump body; and the utility model has the advantages that the auxiliary impeller rotates to generate centrifugal force, the pressure generated by the impeller can be balanced, and when the negative pressure is generated at the auxiliary impeller hub, the pump realizes no-leakage running when in use.

Description

Horizontal no leak sand removing pump

Technical field: the invention is that the pump structure of carrying mortar, ore pulp class medium is improved.

Background technique: when carrying mortar, ore pulp class medium, because the pump of mechanical seal is installed, mechanical seal have under crystallization, the harsh conditions such as impure easy to wear and leak, be difficult to working life guarantee, and the common fillers sealing can not guarantee not have the operation of leakage, and safeguard that change filler bothers very much, increased working strength of workers, using effect neither be very desirable.

Summary of the invention: the purpose of the invention provides a kind of Horizontal no leak sand removing pump that does not leak when carrying mortar, ore pulp class medium; The purpose of the invention is to realize by following branch art scheme: Horizontal no leak sand removing pump is characterized in that being made up of pump cover, the pump housing, impeller nut, impeller, dividing plate, sub-propeller, Stuffing box, muddy packing, Gland, axle, bearing, carriage, bearing gland, shaft coupling; Bearing and bearing gland are contained on axle middle part and the upper end, Gland is contained on the axle, Stuffing box is contained on the axle, adorn bearing between Stuffing box and the axle, in its space, adorn muddy packing, Gland is fixed on the Stuffing box, axle is contained on the carriage, axle upper end dress shaft coupling, sub-propeller is contained in axle upward fixes, dividing plate is contained on the sub-propeller, impeller is contained in axle upward fixes with key, impeller nut with key, the pump housing is fixedlyed connected with carriage, cover at pump housing end opening place armored pump.

The advantage of the invention: when pump in when work, the rotation of sub-propeller produces centrifugal force, the pressure that can the balance impeller produces produces negative pressure in the sub-propeller wheel hub, thereby has realized not having the running of leakage when making pump work; After pump stopped, medium was sealed by muddy packing, because the pressure of the back sealing part of stopping is minimum, thereby filler needn't press very tightly, so just reduced filler with spool wearing and tearing, prolonged working life.

Description of drawings:

Fig. 1 is the Horizontal no leak sand removing pump structural representation.

Among the figure: 1, pump cover 2, the pump housing 3, impeller nut 4, impeller 5, dividing plate 6, sub-propeller 7, Stuffing box 8, muddy packing 9, Gland 10, axle 11, bearing 12, carriage 13, bearing gland 14, shaft coupling

Embodiment: Horizontal no leak sand removing pump is characterized in that being made up of pump cover, the pump housing, impeller nut, impeller, dividing plate, sub-propeller, Stuffing box, muddy packing, Gland, axle, bearing, carriage, bearing gland, shaft coupling; Bearing and bearing gland are contained on axle middle part and the upper end, Gland is contained on the axle, Stuffing box is contained on the axle, adorn bearing between Stuffing box and the axle, in its space, adorn muddy packing, Gland is fixed on the Stuffing box, axle is contained on the carriage, axle upper end dress shaft coupling, sub-propeller is contained in axle upward fixes, dividing plate is contained on the sub-propeller, impeller is contained in axle upward uses key with key, impeller nut is fixed, the pump housing is fixedlyed connected with carriage, use bolt, fixed by nut at pump housing end opening place armored pump lid, is used bolt, nut is fixed, pump cover is shaped on middle through hole, and pump housing side is shaped on outlet.Muddy packing is commercial material.
