Description
Technical field
The present invention relates to vacuum pump technology fields, more specifically more particularly to a kind of liquid-ring vacuum pump.
Background technique
Liquid-ring vacuum pump, it is also possible to make compressor, referred to as liquid-piston compressor.Liquid-ring vacuum pump is initially used as self-priming
Water pump is then gradually available for many industrial departments such as petroleum, chemical industry, machinery, mine, light industry, medicine, food and environmentally friendly soil pick-up.
In industrial many technical process, such as vacuum filter, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, true
Backlash tide and vacuum outgas etc., liquid-ring vacuum pump is widely used.
Existing liquid-ring vacuum pump: gas is in pump chamber by the size lost in air inlet the storehouse extremely flowing of exhaust storehouse and its pole
Limits pressure is to determine that gap minimizes by the gap (impeller both ends of the surface gap should be uniform) of impeller both ends of the surface and end cap disk,
The loss of the mutual channelling of gas is with regard to smaller in each compression bin, in order to guarantee that impeller can normally rotate, impeller both ends of the surface and end cap
It disk end face must retention gap.Existing technique: suitable gap is obtained by cushioning between the pump housing and end cap, or is improved each
Component processing precision controls bearing clearance by processing dimension, also to guarantee that two sides gap is uniform；Operation and processing are very multiple
Miscellaneous, traditional process equipment and technique is it is difficult to ensure that requirement with high accuracy, the interchangeability of batch production is poor, and consistency of performance cannot
It is effectively controlled.Generally for easy to produce, design gaps increasing, and the performance indicator of liquid-ring vacuum pump is reduced, come real
Now produce in batches.
Summary of the invention
It is an object of the invention in view of the above shortcomings of the prior art, provide that a kind of structure is simple and clearance-adjustable
Liquid-ring vacuum pump.
To achieve the above object, the technical solution adopted by the present invention is that: a kind of liquid-ring vacuum pump, including the pump housing, impeller,
Air-breathing disk and end cap, the air-breathing disk are fixed on the inside of end cap, and the pump housing is mounted between the air-breathing disk of both ends, impeller installation
In the pump housing, a radial support bearing is respectively housed on the bearing position at impeller both ends, the radial support bearing is by being set to end
The bearing seat supports of outer side of lid are provided with adjusting seat and radial branch by axially position bearing on the axis rank outer diameter of impeller one end
Support bearing offsets, and in adjusting seat, fixture nut is pressed on the outside of axially position bearing, the fixture nut is set in impeller
Axial end on locked by clamping screw, be equipped with spring shim between fixture nut and clamping screw, the adjusting seat it is outer
Circle by screw thread is connected with positioning seat in turn, the retaining ring being fitted on the outside of positioning seat and the rear cover being fitted on the outside of retaining ring,
The positioning seat is fitted in the outside of radial support bearing and bearing block, and is fixedly connected with the bearing seat by screw.
The present invention adjusts the gap between impeller and air-breathing disk, structure by the way that adjusting seat is arranged on the shaft end of impeller
Simply, easy to adjust, accurate positioning ensure that the minimum clearance between impeller and air-breathing disk, and gap is uniform.
