Abstract
The utility model discloses a mechanism for adjusting a clearance between an impeller and a wear-resisting plate in a dredge self-priming pump, which comprises a pump body, wherein an installing port is arranged at the back end of the pump body, and a bearing body is sleeved in the installing port; an annular flange is arranged on the annular wall of the bearing body, and the outer edge part of the installing port is retained by the annular flange; an installing hole is arranged on the annular flange, and a counterbore corresponding to the installing hole is positioned at the annular edge part of the installing hole on the pump body; and a hexagon socket head bolt is rotatably arranged in the counterbore and is propped on the annular flange. The utility model has the advantages that the mechanism has simple structure, is convenient to manufacture, can achieve the purpose of adjusting the clearance between the impeller and the wear-resisting plate in the dredge self-priming pump, improves the performance of a water pump and reduces the maintenance cost of the water pump.
Description
Technical field:
The utility model relates generally to adjusts the self-priming pump field, relates in particular to a kind of mechanism in gap between impeller and wearing plate that adjusts in the blowdown self-priming pump.
Background technique:
Owing to water pump spindle to the machining accuracy error or owing to reasons such as its being worn in use, can cause water pump to have the fit up gap.If the usability that can influence water pump greatly can not in time be adjusted in the fit up gap.Blowdown self-priming pump particularly, impeller in the blowdown self-priming pump and the gap between the wearing plate generally are to utilize in when assembling to add some pads or alternate manner is disposable adjusts, but, in use, owing to wearing and tearing, string is moving or other reason can produce the gap again, the decreased performance that causes water pump, and the maintenance cost of water pump is very high.
The model utility content:
The utility model purpose is exactly in order to remedy the defective of prior art, and a kind of mechanism in gap between impeller and wearing plate that adjusts in the blowdown self-priming pump is provided, and it is simple in structure, can conveniently adjust the gap between impeller and wearing plate in the self-priming pump.
The utility model is achieved through the following technical solutions:
A kind ofly adjust in the blowdown self-priming pump mechanism in gap between impeller and wearing plate, include the pump housing, pump housing rear end is provided with mount inlet, is set with bearing support in the mount inlet, and the ring wall of bearing support is provided with annular rib, and annular rib is blocked in position, mount inlet outer; Described annular rib is provided with mounting hole, and the ring that is positioned at mount inlet on the described pump housing has the counterbore corresponding with mounting hole along the position, be installed with hexagon socket head cap screw in the counterbore, and hexagon socket head cap screw is against on the described annular rib.
Described a kind of mechanism in gap between impeller and wearing plate that adjusts in the blowdown self-priming pump, it is characterized in that: include inner hexagon spanner, inner hexagon spanner passes the mounting hole on the annular rib and inserts in the hex slot of hexagon socket head cap screw head.
Described bearing support front end is installed organic envelope seat, is rotatablely equipped with rotating shaft in the bearing support, and the rotating shaft front end stretches in the pump housing after passing bearing support and machine envelope seat successively, and rotating shaft front end fixed cover is equipped with impeller, and described impeller front side is provided with wearing plate.
The utility model stretches out the outer length of counterbore and adjusts bearing support and insert the degree of depth in the pump housing by adjusting hexagon socket head cap screw, and then adjusts the axial displacement of rotating shaft, finally obtains adjusting the purpose in gap between impeller and the wearing plate.
The utility model has the advantages that:
The utility model is simple in structure, and is easy to make, can realize adjusting in the blowdown self-priming pump purpose in gap between impeller and wearing plate, improved the performance of water pump, reduced the maintenance cost of water pump.
Description of drawings:
Fig. 1 is the structural representation of blowdown self-priming pump.
Fig. 2 is the structure enlarged view at bearing support position.
Embodiment:
Referring to accompanying drawing.
A kind ofly adjust in the blowdown self-priming pump mechanism in gap between impeller and wearing plate, include the pump housing 1, the pump housing 1 rear end is provided with mount inlet, is set with bearing support 2 in the mount inlet, and the ring wall of bearing support 2 is provided with annular rib 3, and annular rib 3 is blocked in position, mount inlet outer; Described annular rib 3 is provided with mounting hole, and the ring that is positioned at mount inlet on the described pump housing 1 has the counterbore corresponding with mounting hole along the position, be installed with hexagon socket head cap screw 5 in the counterbore, and hexagon socket head cap screw 5 is against on the described annular rib 3.Include inner hexagon spanner 4, inner hexagon spanner 4 passes the mounting hole on the annular rib and inserts in the hex slot of hexagon socket head cap screw 5 heads.Described bearing support 2 front ends are installed organic envelope seat 6, are rotatablely equipped with rotating shaft 7 in the bearing support 2, and rotating shaft 7 front ends stretch in the pump housing 1 after passing bearing support 2 and machine envelope seat 6 successively, and rotating shaft 7 front end fixed covers are equipped with impeller 8, and described impeller 8 front sides are provided with wearing plate 9.
