Abstract
The utility model relates to a single-stage single-suction vortex pump. The single-stage single-suction vortex pump is formed by a pump cover, a pump body, an impeller, a packing gland, a shaft, a bearing frame and an O-shaped sealing ring. The pump cover can be moved to an appropriate position back and forth by rotating screws on the pump cover, and thus gaps among the impeller, the pump cover and the pump body can be regulated. According to the single-stage single-suction vortex pump disclosed by the utility model, axial gaps can be conveniently regulated to meet the design requirement after the impeller is abraded, the service life of the single-stage single-suction vortex pump is obviously prolonged, and the single-stage single-suction vortex pump does not need to be disassembled; the structure is simple, and the installation is convenient.
Description
Technical field
The utility model relates to a kind of one step single sucking peripheral pump.
Background technique
At present, the one step single sucking peripheral pump on market, is all comprised of the pump housing, impeller, pump cover, Gland, axle, bearing bracket stand etc., and the monolateral gap design between impeller and the pump housing, pump cover is between 0.1-0.15.The shortcoming of this structure is: to the processing dimension of part, particularly length dimension requirement is tight, thereby causes processing cost high, after particularly pump uses and must be the time, due to the wearing and tearing of impeller, cause gap to increase, thereby affect pump performance, progress causes pump normally not use.
Summary of the invention
The purpose of this utility model is: provide a kind of by the screw on turn pump cover, thereby make pump cover move forward and backward correct position to regulate the one step single sucking peripheral pump in the gap of impeller and pump cover, the pump housing.
It is achieved in that it is comprised of pump cover, the pump housing, impeller, Gland, axle, bearing bracket stand, O-ring seals.Between pump cover 1 and the pump housing 3, be provided with O-ring seals 9; On pump cover 1, be designed with O shape groove 10, on the outer round flange of pump cover, be designed with in three silk holes 11 and 2, three through holes of three screws of the interior installation in 12, three silk holes 11 of three through holes three screws 8 are installed.
The utility model has the advantage of: it can carry out easily axial clearance and adjust to designing requirement after damage in impeller, the working life of significant prolongation pump, and do not need to dismantle pump; Simple in structure, easy for installation.

Embodiment
The utility model is comprised of pump cover 1, the pump housing 3, impeller 4, Gland 5, axle 6, bearing bracket stand 7, O-ring seals 9 etc.Between pump cover 1 and the pump housing 3, be provided with O-ring seals 9; On pump cover 1, be designed with O shape groove 10, on the outer round flange of pump cover, be designed with in three silk holes 11 and 2, three through holes of three screws of the interior installation in 12, three silk holes 11 of three through holes three screws 8 are installed.
In the time need to regulating the gap of impeller 4 and pump cover 1, the pump housing 3, the screw 2 on turn pump cover, makes pump cover 1 move forward and backward correct position, then tights a bolt 8.
Claims (1)
