Abstract
The utility model relates to an open impeller with adjustable clearance, which comprises a pump body, a pump shaft, an impeller, an impeller pressplate, an impeller nut, and a base. The utility model is characterized in that the impeller is located in the inner cavity of the pump body, and the pump shaft end is fixedly connected by the impeller nut and the impeller pressplate. At bottom of the pump body relative to the impeller plane, a through hole is provided corresponding to the impeller. A base is located in the through hole. On the base, a plurality of threaded holes are provided. In the threaded holes, adjusting bolts are provided. On the outer circles of the adjusting bolts, threads are provided to match with the threads in the threaded holes. The center of each adjusting bolt is provided with a through hole in axial direction. Bolts are inserted into the through holes to fixedly connect the pump body, the base and the adjusting bolts. The utility model has the advantage that after the vanes become worn, the clearance between the open impeller and the base can be adjusted easily by changing the screwing depth of the adjusting bolts, so as to improve the throughput of sewage for a submersible blowoff pump.
Description
Technical field
The utility model relates to a kind of controlling device, particularly a kind of open impeller gap regulator.
Background technique
When proof submersible sand discharging pump adopts the unshrouded impeller structure at present, be to use in the occasion that long fibre and big solid particle are arranged for pump, gap between blade and the base is extremely important, be controlled in certain scope, and the wearing and tearing of blade in use are very fast, of long duration, excesssive gap, the function of pump just can not have been brought into play fully, and still the gap between existing proof submersible sand discharging pump unshrouded impeller and the base can't conveniently be adjusted, and causes the dirt passing capacity of proof submersible sand discharging pump to reduce.
Summary of the invention
Thereby the purpose of this utility model is to solve the problem that dirt passing capacity that proof submersible sand discharging pump in the prior art adopts gap between existing impeller of unshrouded impeller and the base conveniently to be adjusted to cause proof submersible sand discharging pump reduces, and a kind of open impeller gap regulator is provided.The utility model designs a kind of open impeller gap regulator, comprise the pump housing, pump shaft, impeller, the impeller pressing plate, impeller nut, base, it is characterized in that: impeller is positioned at the inner chamber of the pump housing, by impeller nut and the fixedly connected pump shaft end of impeller pressing plate, have and the corresponding through hole of impeller in pump housing bottom with respect to paddle wheel plane, there is a base to be positioned at through hole, several tapped holes are arranged on the base, the adjusting bolt is arranged in tapped hole, screw thread with the tapped hole threads engaged is arranged on the cylindrical of adjusting bolt, the center of regulating bolt has through hole vertically, has screw to penetrate the fixedly connected pump housing of through hole, base and adjusting bolt.The utility model has the advantages that behind blade wear, just can improve the dirt passing capacity efficient of proof submersible sand discharging pump by changing the gap that the degree of depth is regulated unshrouded impeller and base easily that is screwed into of regulating bolt.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
Embodiment
Comprise the pump housing 1 among the figure, pump shaft 2, impeller 3, impeller pressing plate 4, impeller nut 5, base 6, it is characterized in that: impeller 3 is positioned at the inner chamber of the pump housing 1, by impeller nut 5 and impeller pressing plate 4 fixedly connected pump shaft 2 ends, have and impeller 3 corresponding through holes 7 in the pump housing 1 bottom with respect to impeller 3 planes, there is a base to be positioned at through hole 7, several tapped holes 9 are arranged on the base 6, the bolt 10 of adjusting is arranged in tapped hole 9, screw thread with tapped hole 9 threads engaged is arranged on the cylindrical of adjusting bolt 10, the center of regulating bolt 10 has through hole 11 vertically, has screw 12 to penetrate the through hole 11 fixedly connected pump housings 1, base 6 and adjusting bolt 10.In the use, regulate the gap of impeller 3 and base 6 as needs, as long as will regulate in the tapped hole 9 that bolt 10 is screwed into base 6, until reaching the reasonable clearance of unshrouded impeller 3 with base 6, with screw 12 pump housing 1, base 6 and adjusting bolt being twisted 10 tightlier is the gap of can regulate unshrouded impeller 3 and base 6.
