The lubricating oil passage or the lubricating oil cavity is internally provided with a filtering device which can be a disc-shaped magnetic filtering net; and the circumference of the filtering device is connected with the bottom part of the shell by a welding mode. The utility model has simple structure, and can effectively improve reliability of the working of the compressor and the service life.

Description

A kind of compressor

Technical field

The utility model relates to a kind of compressor.

Background technique

Compressor is usually used in the fields such as air-conditioning, its processing and assembly precision are very high, so the purity requirement to the medium in the compressor is also very high, but in practical work process, the workpiece of compressor inside is (as the sound vortex, bent axle, stator, rotor, eccentric masss etc.) iron of break-in generation is cut, when compressor connects miscellaneous equipment, the welding slag that miscellaneous equipment produced, wearer, the oxide carbide that produces during the compressor high temperature operation etc. all can stockpile in compressor, a large amount of impurity enters can cause the stuck or damage of compressor in the compressor, be accumulated on the motor coil and can cause the motor short circuit, burn, flowing into compressor lubrication system can cause oil circuit to stop up, briefly, impurity in the compressor can cause fatal harm to compressor, influence the stability of compressor operating, reliability, the working life of serious reduction compressor.

Summary of the invention

The purpose of this utility model is to provide the compressor of a kind of reliability height, long service life.

The utility model is achieved through the following technical solutions:

A kind of compressor comprises housing, is provided with oil leab or lubricant reservoir that workpiece and circulation communicate in housing, is provided with filtrating equipment in oil leab or lubricant reservoir.

Enter into the abrasive dust that welding slag, workpiece produced of impurity in the compressor, compressor inner piece from miscellaneous equipment, lodge in the lubricant reservoir or oil leab in the compressor housing, be provided with after the filtrating equipment, flow through the lubricant oil of oil leab or lubricant reservoir through filtering, impurity in the lubricant oil is eliminated, reduce the influence of impurity as much as possible, improve the reliability and the working life of compressor operating the compressor operating parts.

Further structure of the present utility model is:

Described lubricant reservoir is positioned at the bottom of described housing at least, and described filtrating equipment is located at described housing bottom.Because impurity is mainly metal impurities, lodges in the bottom of housing mostly, and filtrating equipment is located at housing bottom, its filtering effect is better.

Described workpiece comprises bent axle, is provided with described oil leab in bent axle, and insert in the described lubricant reservoir of described housing bottom the lower end of bent axle; Described filtrating equipment is located between the described lubricant reservoir and the described oil leab in the bent axle of described housing bottom.

Described filtrating equipment is the plate-like filter screen, and the periphery of this plate-like filter screen is connected with the bottom of described housing, and the middle part of plate-like filter screen is a center hole, and described bent axle inserts this center hole.Particularly, described filter screen is in the form of annular discs, is provided with retainer ring at the periphery of this discoid filter screen, is provided with inner ring in described central hole, is connected by the filter screen skeleton between inner ring and the retainer ring, and described filter screen skeleton is radial direction, and circumferentially uniform along described filter screen; The retainer ring of described filter screen periphery is welded to connect by the bottom of two soldering points and described housing at least.This structure is easy to process, and cost is low.

Described filtrating equipment is a magnetic filter device, and promptly filtrating equipment need or directly adopt magnetic material to make through magnetization, and through out-of-date, this filtrating equipment plays a role in filtering at metal impurities, and simultaneously metal impurities is adsorbed.

Embodiment

As shown in Figure 1 to Figure 3, a kind of scroll compressor comprises housing 1, is provided with oil leab or lubricant reservoir that workpiece and circulation communicate in housing 1, is provided with filtrating equipment in oil leab or lubricant reservoir.

Wherein, described filtrating equipment is discoid magnetic screen 7, and the workpiece of being located in the housing 1 includes bent axle 2, stator 3, rotor 4 etc., and lubricant reservoir 5 is positioned at the bottom of housing 1 at least, is provided with oil leab 6 in bent axle 2; The periphery of discoid filter screen 7 is provided with retainer ring 8, retainer ring 8 is welded to connect by the bottom of four soldering points 12 with housing 1, the middle part of plate-like filter screen 7 is a

center hole

10,10 places are provided with inner ring 9 at center hole, filter screen skeleton 11 is radial direction, and circumferentially uniform and inner ring 9 is connected with retainer ring 8 along filter screen 7, the lower end of bent axle 2 is inserted this center hole 10 and is fed in the lubricant reservoir 5 of housing 1 bottom.

The present embodiment assembling is simple, as shown in Figure 3, only need 7 of filter screens to be welded in compressor housing 1 bottom by four soldering points 12, guarantee that the applying of filter screen 7 imperforate face and compressor housing 1 bottom gets final product, filter screen 7 can be provided with according to the compressor situation, if it is not very strict that compressor assembly requires impurity, can suitably reduce grid order number, be arranged on about 60～100 orders, if impurity is required relatively strictness, grid order number can be arranged between 100～140 orders, the material of filter screen 7 can be that common metal is made, through magnetization, make filter screen 7 have filtration and suction-operated simultaneously then; The bent axle 2 that Oil Guide sheet 13 is housed inserts the about 5mm of filter screen 7 central depths, and remains on 1mm with 7 liang of back gauges of filter screen, guarantees that bent axle 2 operation process do not interfere; The impurity such as abrasive dust that welding slag, workpiece produced that enter into impurity in the compressor, compressor inner piece from miscellaneous equipment are filtered repeatedly to be removed, effectively reduce the influence of impurity, improve the reliability and the working life of compressor operating the compressor operating parts.
