Abstract
A magnetic filter for a compressor comprises a woven wire filter and an installation flange thereof, and the periphery of the woven wire filter is arranged with more than one permanent magnet strip. The two ends of the permanent magnet strip are provided with an installation plate respectively, the two ends of the permanent magnet strip are respectively fixed on the installation plates; and one installation plate at one end is connected with the installation flange. The woven wire filter is covered by the permanent strip and the installation plates. The magnetic filter for a compressor can form enough magnetic force at the periphery of the woven wire filter after increasing the permanent magnet strip at the periphery of the woven wire filter, thus leading the metal impurity in the lubricating oil flowing through the permanent magnet strip to be completely magnetized, and ensuring the lubricating oil of the compressor free-flowing. The frozen lubricating oil after being magnetized the metal impurity by the permanent magnet strip flows into the woven wire filter, and other non-metal impurities are filtered by the woven wire filter, which makes the lubricating oil flowing out from an oil outlet to be kept clean, thereby ensuring the lubricating oil flowing into the compressor to meet requirement, and ensuring the safety operation of the compressor.
Description
Technical field
The utility model relates to a kind of magnetic filter, mainly is applicable to the metal impurities that filter lubricant oil in the refrigeration compressor.
Background technique
At present, in vapor compression type refrigerating system, because refrigerant and refrigeration lubrication oil mix, contain a large amount of metal impurities in the refrigeration lubrication oil that the process compressor air-discharging is separated, the unit that particularly new assembling is come into operation, because the break-in between each moving element can produce a large amount of metal impurities and be blended in the circuit refrigeration lubrication oil.In compressor operating, this part impurity can flow in the oil groove with compressor lubricant oil, stops up the wire gauze filter in the oil groove.Because existing refrigeration compressor only has the impurity in the wire gauze filter filtering lubricant oil,, can cause wire gauze filter to stop up when wire mesh holes order number is provided with when too much; Even because of excessive damage of wire gauze filter turnover pressure at two ends difference.When wire mesh holes order number is provided with when very few, can cause wire gauze filter trickle metal impurities can not be filtered, the metal impurities that are not filtered of part flow into compressor with lubricant oil, and are light then quicken the heavy wear of compressor, heavy then cause compressor stuck.The both can cause fatal infringement to compressor.
The model utility content
The purpose of this utility model aims to provide a kind of simple and reasonable, easy to assembly quick, effective compressor magnetic filter of the metal impurities in the adsorpting lubrication oil, to overcome deficiency of the prior art.
A kind of compressor magnetic filter by the design of this purpose comprises wire gauze filter and mounting flange thereof, and its structure characteristic is to be equipped with permanent magnetism iron bar more than one in the wire gauze filter outer periphery.
The two ends of described permanent magnetism iron bar are provided with mounting plate, and the two ends of permanent magnetism iron bar are separately fixed on the mounting plate; And an end mounting plate and mounting flange join.The permanent magnetism iron bar is straight, inclination or helical are centered around the wire gauze filter periphery; Perhaps an end of permanent magnetism iron bar is fixed on the mounting plate, and the other end and mounting flange join.
Described permanent magnetism iron bar and mounting plate cover wire gauze filter.The permanent magnetism iron bar is that the 2-10 root is uniform.Mounting plate is that nonmetallic material are made.
This permanent magnetism iron bar of the present utility model can form enough magnetic force in that wire gauze filter is peripheral, makes metal impurities in the lubricant oil of the permanent magnetism iron bar of flowing through by magnetic fully.Metal impurities behind the magnetic are adsorbed on the permanent magnetism iron bar; Metal impurities can not come off under the situation of enough external force not having.Through the lubricant oil behind the impurity magnetic is filtered through wire gauze filter again, make the lubricant oil of the wire gauze filter of flowing through not have metal impurities, wire gauze filter can not result in blockage because of impurity.It is excessive that it has stopped the wire gauze filter turnover pressure at two ends difference that wire gauze filter causes because of impurity stops up, and causes wire filter net breakage, flat flat even damage phenomenon such as inefficacy.
Behind the peripheral increase of wire gauze filter permanent magnetism iron bar, can guarantee effectively that the compressor lubricant oil circulation is smooth and easy.Flowed into wire gauze filter by the oil of the refrigeration lubrication behind the permanent magnetism iron bar magnetic metal impurities, wire gauze filter filters other nonmetallic inclusion, make the lubricant oil that flows out from oil outlet keep clean, thereby guarantee that the lubricant oil that flows into compressor meets the demands, and guarantees compressor operating safety.
Description of drawings
Accompanying drawing 1 is the utility model one example structure schematic representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1, this compressor magnetic filter comprises wire gauze filter 3 and mounting flange 1 thereof, is equipped with permanent magnetism iron bar 4 more than one in wire gauze filter 3 outer periphery.The two ends of permanent magnetism iron bar are separately fixed on the mounting plate 2, and an end mounting plate 2 joins with mounting flange 1.Permanent magnetism iron bar 4 and mounting plate 2 cover wire gauze filter 3.
Refrigeration lubrication oil is when flowing through this magnetic filter, because the permanent magnetism iron bar of magnetic filter is to the magnetic effect of metal impurities, the metal impurities in the refrigeration lubrication oil all are adsorbed on the permanent magnetism iron bar.Rationally lay the permanent magnetism iron bar at the wire gauze filter periphery, can guarantee metal impurities in whole magnetic refrigeration lubrication oil.Flowed into wire gauze filter by the oil of the refrigeration lubrication behind the permanent magnetism iron bar magnetic metal impurities, after other impurity was filtered, clean refrigeration lubrication oil was discharged by oil outlet 5, sends into the compressor lubrication oil duct, carried out next lubricated circulation.
