Description
Technical field
Water ring pump field is the utility model is related to, is a kind of impeller adjusting device of water ring pump.
Background technology
Water ring pump is a kind of rough vacuum pump, it is also possible to makees compressor, referred to as liquid piston compressor.Water ring pump is initially used as certainly
Pulsating pump, then it is gradually available for many industrial departments such as oil, chemical industry, machinery, mine, light industry, medicine and food.It is raw in industry
Production many technical process in, as vacuum filter, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum conditioning and
Vacuum outgas etc., water ring pump is widely used.
Existing water ring pump：The size and its limit pressure that gas loses in being flowed in pump chamber by air inlet to exhaust outlet
Power, determined by impeller both ends of the surface and the gap of end cap disk, impeller both ends of the surface gap should be uniform.Existing technique：By the pump housing and
Cushioning obtains suitable gap between end cap, or improves each component processing precision, and bearing clearance is controlled by processing dimension,
Also to ensure two sides gap uniformity；Operate and process very complicated, consistency of performance can not be effectively controlled.Generally for just
In production, control range increases, and reduces the performance indications of water ring pump.
The content of the invention
The purpose of this utility model is to overcome the problem of above-mentioned present in water ring pump in the prior art, there is provided a kind of structure
Simply, water ring pump configuration easy to adjust, assembly cost is low.
The utility model is achieved like this：A kind of impeller adjusting device of water ring pump, it is characterized in that air-breathing disk is consolidated
It is scheduled on the inside of end cap, the pump housing is arranged between the air-breathing disk of both ends, and bearing block is fixed on the outside of end cap, and bearing outer ring is fixed on
On bearing block, impeller bearings at both ends position is arranged on bearing inner race, is fixed on the outside of bearing outer ring by bearing cap, on the outside of bearing inner race
Location nut is installed, location nut is radially drilled with positioning hole, copper packing is added in positioning hole, copper packing external lock has lock-screw.
By adopting the above-described technical solution, it is simple in construction, easy to operate, assembly cost is low, shaft core and impeller concentricity
It is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1st, location nut；2nd, copper packing；3rd, lock-screw；4th, bearing cap；5th, bearing；6th, bearing block；7th, end cap；
8th, air-breathing disk；9th, the pump housing；10th, impeller.
Embodiment
The utility model is described in further detail with example below in conjunction with the accompanying drawings.
In Fig. 1, air-breathing disk 8 is fixed on the inner side of end cap 7, and the pump housing 9 is arranged between both ends air-breathing disk 8, bearing block 6
The outside of end cap 7 is fixed on, the outer ring of bearing 5 is fixed on bearing block 6, and the bearings at both ends position of impeller 10 is arranged on the inner ring of bearing 5,
Fixed on the outside of the outer ring of bearing 5 by bearing cap 4, location nut 1 is installed on the outside of the inner ring of bearing 5, the radial direction of location nut 1 is drilled with positioning
Hole, copper packing 2 is added in positioning hole, the external lock of copper packing 2 has lock-screw 3.
The outer ring of the design middle (center) bearing 5 is fixed on bearing block 6, adjusts location nut 1, is eliminated bearing clearance, is forced impeller
10 is movable, during the gap uniformity being moved between impeller 10 and air-breathing disk 8, the locking screw of the side of screwed in place nut 1
Nail 3, lock-screw 3 oppress the positioning threads that copper packing 2 is engaged in the shaft core of impeller 10, position impeller 10 immovable, so as to protect
Demonstrate,prove running accuracy.Copper packing 2 has modeling deformation performance well, and occlusion screw thread is without injuring screw thread, after lock-screw 3 unclamps, uses
Hook-shaped wrench rotational positioning nut 1, can be with adjustment.It is simple in construction, easy to adjust, apply repeatedly, ensure impeller 10 and air-breathing
Minimum clearance between disk 8, and gap uniformity.
