Description
Technical field
The utility model relates to a kind of pump, particularly relates to the pump that accurately can regulate gap between a kind of impeller and pump cover.
Background technique
Pump is conveying liquid or the machinery making fluid pressurization.It sends the mechanical energy of prime mover or other external energies to liquid, and liquid energy is increased.Bearing in existing pump by location snap ring directly and bearing housing be fixed, impeller shaft is arranged in bearing, one end of impeller shaft is fixed with impeller, and after long-term use, can wear and tear in impeller cover place, after wearing and tearing volume increases, gap between impeller and pump cover can increase gradually, now, needs to carry out dismantling the replacing carrying out impeller, waste time and energy, and it is also larger to change impeller expense.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model proposes the pump that between a kind of impeller and pump cover, gap is adjustable.
The purpose of this utility model, will be achieved by the following technical programs:
The pump in a kind of adjustable impeller and pump cover gap, comprise the pump housing, described pump housing one end is provided with a bearing housing, be equipped with impeller shaft in described bearing housing, the pump housing side of described impeller shaft is fixed with an impeller, and described bearing housing is that internal thread is arranged, a bearing support block is connected with in described bearing housing, described bearing support block is that outside thread is arranged, and described impeller shaft is fixed in bearing support block by bearing, the axial motion of described bearing support block Sports band movable vane wheel.
Preferably, the inwall of described bearing support block offers an annular groove, and described bearing is fixed in bearing support block by location snap ring, and described location snap ring is arranged in annular groove.
Preferably, the other end of described bearing support block is also provided with locking nut, and described bearing support block is connected by locking nut with bearing housing.
The utility model gives prominence to effect: can carrying out as required regulating the distance between impeller and pump cover, can reach adjustment object without the need to carrying out dismounting, convenient and swift.Extend the working life of impeller, decrease maintenance cost.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail embodiment of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As Fig. 1, the utility model discloses the pump in a kind of adjustable impeller and pump cover gap, consistent with prior art, comprise the pump housing (meaning not shown in the figures), described pump housing one end is provided with a bearing housing 110, be equipped with impeller shaft 160 in described bearing housing 110, described impeller shaft 160 is fixed with an impeller 300 in pump housing side.
Unlike the prior art, be also improvement of the present utility model, described bearing housing 110 is arranged for internal thread, is connected with a bearing support block 120 in described bearing housing 110 simultaneously, and described bearing support block 120 is outside thread setting.Fixed by screw thread between described bearing support block 120 and bearing housing 110.Fixing for what strengthen between the two, one end of described bearing support block 120 offers tapped hole, further locks by lock screw 170.
Concrete, described impeller shaft 160 is fixed in bearing support block 120 by bearing 140, the inwall of described bearing support block 120 offers an annular groove (meaning not shown in the figures), described bearing 140 is fixed in bearing support block by location snap ring 130, and described location snap ring 130 is arranged in annular groove.
Now, bearing support block 120, with impeller shaft 160 and impeller 300 as a whole, when rotary bearing supporting base 120, can impeller move.Concrete, when bearing support block 120 rotates, actual is carry out axial movement in bearing housing 110, and then impeller 300 does axial movement, impeller 300 just can and pump cover 200 between carry out the adjustment of distance.
The position of the described pump cover 200 mentioned in the utility model and all identical with the pump of prior art for being fixed these by locking nut 150 between impeller shaft 160 with bearing 140, be prior art, therefore do not repeated them here.
In the utility model, after the wearing and tearing of impeller bonnet, the gap between impeller and pump cover becomes large, by regulating bearing support block the position of impeller can be adjusted, after adjusting to correct position, is further fixed by the lock screw on bearing support block.Without the need to changing or dismounting impeller, well can regulate, decreasing maintenance cost and waiting time of machine halt, practical.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technological schemes formed, and all drops within protection domain of the present utility model.
