Abstract
The utility model discloses a rotary vane compressor of a new lubrication system, which comprise a front bearing, a compressor cylinder body, a compressor rotor shaft, a rear bearing, an oil separator, an oil storage tank of the rotary vane compressor and all other parts of the rotary vane compressor, and is characterized in that the rear bearing is provided with two oil delivery openings. One oil delivery opening is communicated with the oil storage tank and the rear bearing as well as a contacting surface of the rotor shaft of the compressor, and the other oil delivery opening is communicated with a gap of end plane of the rotor shaft of the compressor and a back pressure groove of a rotary vane of the compressor. An axis of the rotor shaft of the compressor is provided with the oil delivery opening with two enclosed ends along the direction of the length of the shaft. The oil delivery opening is respectively communicated with the front bearing and the rear bearing along the radial direction of the rotor shaft of the compressor by the axle. The rotary vane compressor of the utility model has more reasonable lubrication system, more reasonable layout of the lubricating channels, and greatly simplifies the processing technique of the rotary vane compressor, reduces the manufacturing cost of the compressor and shortens the production cycle of the compressor.
Description
One, affiliated technical field
The utility model belongs to refrigeration and air-conditioning technical and power field, relates to a kind of rotary blade type compressor, the rotary blade type compressor of particularly a kind of novel lubricating system.
Two, background technique
The lubrication system of the rotary blade type compressor of extensive use at present as shown in Figure 1, the operation of lubrication system need lean against on the rear bearing, fore bearing, cylinder body of compressor respectively the oil supply hole of processing and finish.This lubrication system need be processed oil supply hole on 3 compressor parts, and needs to process the oil supply hole of an inclination on the compressor fore bearing, and the processing of the oil supply hole of this inclination is the comparison difficulty.These all make the processing technology of compressor very complicated, thereby make the manufacture cycle of compressor longer.
Three, summary of the invention
Defective and deficiency according to above-mentioned prior art existence, the purpose of this utility model is, the rotary blade type compressor of a kind of novel lubricating system is proposed, this rotary blade type compressor does not change the component and the assembling thereof of original rotary blade type compressor, reset oil circuit, thereby improve the processing technology of rotary blade type compressor, shorten the manufacture cycle of compressor.
To achieve these goals, the technological scheme that the utility model adopted is, the rotary blade type compressor of this novel lubricating system comprises, all component of the fore bearing of rotary blade type compressor, compressor casing, compressor drum axle, rear bearing, oil separator, oil storage pool and other rotary blade type compressor; It is characterized in that rear bearing is provided with two oil supply holes, an oil supply hole is communicated with the surface of contact of oil storage pool and rear bearing and compressor drum axle, and another oil supply hole is communicated with the back pressure groove of compressor drum axial end gap and compressor vane; The axle center has the oil supply hole that two ends are sealed along the length direction of axle on the compressor drum axle, and this oil supply hole radially is communicated to fore bearing and rear bearing respectively by the axle center along the compressor drum axle.
Described rear bearing is communicated with the hole in compressor drum axial end gap for radially being provided with.
The rotary blade type compressor of lubrication system of the present utility model, the layout of its lubrication channel is more reasonable, oil supply hole that tilts in processing on the fore bearing and the technology of on compressor casing, processing oil circuit have been saved, easy to process, can simplify the rotary blade type compressor processing technology greatly, reduce the compressor manufacture cost, shorten the manufacture cycle of compressor.
Four, description of drawings
Fig. 1 is the lubrication system schematic representation of existing rotary blade type compressor;
Fig. 2 is a rotary blade type compressor lubrication system schematic representation of the present utility model.
Symbol shown in Fig. 1 and Fig. 2 is represented respectively: 1 fore bearing, 2 cylinder bodies, 3 rotor shafts, 4 rear bearings, 5 oil separators, 6 oil storage pools.
Five, embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 2, according to the technical solution of the utility model, the rotary blade type compressor of this novel lubricating system comprises: each component of rotary blade type compressor body mainly comprise fore bearing 1, compressor casing 2, compressor drum axle 3, rear bearing 4, oil separator 5 and oil storage pool 6.Rear bearing 4 is provided with an oil supply hole radially, and this oil supply hole is communicated with the surface of contact of the oil storage pool 6 of compressor and compressor drum axle 3 and rear bearing 4.The axle center of the rotor shaft 3 of rotary blade type compressor has the oil supply hole of two ends sealing along the length direction of axle.At the fore bearing 1 and rear bearing 4 places of compressor drum axle 3, along rotor shaft 3 radially have two oil supply holes by the axle center, these two oil supply holes are communicated with axial oil supply hole, to reach the purpose to the front and back bearings fuel feeding.
Lubricant oil in the oil storage pool is at the surface of contact that by the oil supply hole on the rear bearing 4 oil is fed to compressor drum axle 3 and rear bearing 4 under the effect of pressure reduction, then by two on the rotor shaft 3 radially oil supply hole and axially oil supply hole supply with the fore bearing 1 of compressor, play lubricated effect; On the other hand, lubricant oil on rotor shaft 3 end faces is given the back pressure groove fuel feeding of vane simultaneously by the axial oil supply hole on the rear bearing 4, lubricant oil can be communicated with in the bottom of the blade groove of rotor shaft 3, play the effect of back pressure, thereby reduce the leakage of compressor, simultaneously also can more effective lubricated front and back bearings.
The lubricant oil that leaks into compression chamber in compressor operation can be discharged compression chamber with pressurized gas, and by the separation of oil separator, last lubricant oil is got back to oil storage pool 6.
Rotary blade type compressor of the present utility model has more rational lubrication system, and the layout of lubrication channel is more reasonable, can simplify the rotary blade type compressor processing technology greatly, reduces the compressor manufacture cost, shortens the manufacture cycle of compressor.
