Abstract
The utility model discloses a mechanism used for adjusting a clearance between an impeller and a wear-resistant plate of a sewage discharging self-priming pump, which comprises a pump body. The rear end of the pump body is provided with a sewage discharging port, a rear cover is arranged outside the sewage discharging port in a covering way and comprises a cylindrical spigot and an annular block edge, the cylindrical spigot is inserted in the sewage discharging port, the annular block edge is arranged on the outer edge part of the sewage discharging port in a blocking way, the annular outer edge part of the sewage discharging port is provided with a counter bore, the annular block edge is provided with a mounting hole corresponding to the counter bore, an adjusting bolt with a central hole is screwed in the mounting hole, a double-ended bolt is screwed in the central hole of the adjusting bolt, the front end of the double-ended bolt is screwed in the counter bore, the rear end of the double-ended bolt is screwed with a long nut, and the long nut props against the outer end part of the adjusting bolt. The mechanism has a simple structure, is convenient to manufacture, and can adjust the clearance between the impeller and the wear-resistant plate of the sewage discharging self-priming pump, thus the performance of the pump is improved and the maintenance cost of the pump is reduced.
Description
Technical field:
The utility model relates generally to adjusts the self-priming pump field, relates in particular to the mechanism that is used for adjusting gap between blowdown self-priming pump impeller and wearing plate.
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, is provided for adjusting in the blowdown self-priming pump mechanism in gap between impeller and wearing plate, 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:
Be used for adjusting the mechanism in gap between blowdown self-priming pump impeller and wearing plate, include the pump housing, pump housing rear end has sewage draining exit, the sewage draining exit enclosing cover is equipped with bonnet, it is characterized in that: described bonnet includes tubular socket and annular rib, the tubular socket inserts in the sewage draining exit, annular rib retaining is at the position, outer of sewage draining exit, the position, annular outer of described sewage draining exit has counterbore, has the mounting hole corresponding with counterbore on the annular rib, is installed with the adjustment bolt that has center hole in the mounting hole, be installed with stud bolt in the center hole of adjustment bolt, the stud bolt front end screws in the counterbore, and its rear end is installed with long nut, and long nut is against the outer end of adjusting bolt.
The utility model is adjusted the length that nut stretches out mounting hole on the bonnet by regulating, and adjusts the spacing between the bonnet and the pump housing, makes bonnet drive wearing plate and produces axial displacement, realizes adjusting the purpose in gap between wearing plate and the impeller.
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 a structural representation of the present utility model.
Fig. 2 is the structural representation of water pump.
Embodiment:
Referring to accompanying drawing.
Be used for adjusting the mechanism in gap between blowdown self-priming pump impeller and wearing plate, include the pump housing 1, the pump housing 1 rear end has sewage draining exit, the sewage draining exit enclosing cover is equipped with bonnet 2, bonnet 2 includes tubular socket 3 and annular rib 4, tubular socket 3 inserts in the sewage draining exit, annular rib 4 retainings are at the position, outer of sewage draining exit, the position, annular outer of described sewage draining exit has counterbore, has the mounting hole corresponding with counterbore on the annular rib 4, is installed with the adjustment bolt 5 that has center hole in the mounting hole, be installed with stud bolt 6 in the center hole of adjustment bolt 5, stud bolt 6 front ends screw in the counterbore, and its rear end is installed with long nut 7, and long nut 7 is against the outer end of adjusting bolt 5.During work, the wearing plate 8 that bonnet 2 drives in the blowdown self-priming pump produces axial displacement, realizes adjusting the purpose in gap between wearing plate 8 and the impeller.
