The present invention will now be further described with reference to the accompanying drawings, in which:
in the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "left", "right", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, and are only for convenience of description of the present invention, and therefore, cannot be understood as a limitation on the practical use direction of the present invention.
The utility model discloses a detailed description:
the utility model provides an adsorption structure of clean refrigeration oil impurity, includes compressor housing 1 and assembles lower cover 2 in compressor housing 1 bottom, lower cover 2 is provided with the cavity structure, adsorption structure still is equipped with adsorption component 3, adsorption component 3 laminating is connected lower cover 2.
The top surface of the lower cover 2 is formed into an arc-shaped lower concave surface by being depressed downwards.
The compressor housing 1 is circular as a whole.
The adsorption component 3 is arranged in a ring shape and is attached to the lower cover 2, and the adsorption component 3 is a magnet block.
The utility model discloses a theory of operation:
the cavity structure is designed on the lower cover 2, so that the oil level height is improved, and the invalid oil quantity is reduced, but as the refrigerant oil and the refrigerant are continuously circulated in the compressor and the system, metal impurities such as metal oxide skin, scrap iron, iron powder and the like existing in the compressor or the air conditioning system can circulate in the air conditioning system along with the refrigerant and the refrigerant oil and enter the compressor; under the high pressure inside the compressor, the flow of the refrigerant oil and the gravity of the metal impurities themselves, the metal impurities are mostly accumulated at the bottom of the refrigerant oil pool (i.e., the bottom of the compressor housing 1). Along with the compressor constantly moves, the refrigeration oil sump is stirred ceaselessly, and these metallic impurity can be inhaled compressor pump body inside under the effect of centrifugal force, because the pump body is inside to belong to accurate part and compressor running speed is very high, tiny impurity all can cause the wearing and tearing of compressor pump body part or lead to the card of roller, gleitbretter part to die in the cylinder, lead to the compressor further wearing and tearing or unable operation, so the impurity problem is huge to the harm of compressor. The annular structure magnet block is added to the cavity structure of the lower cover 2, and the magnet block is added to the circumferential side of the metal cavity of the compressor, so that the adsorption effect on metal impurities such as scrap iron, iron powder and the like is enhanced. On the basis of not occupying the original space of the compressor, the metal impurities such as iron filings and iron powder in the refrigerating oil pool are adsorbed, the refrigerating oil is constantly stirred during the operation of the compressor, and when the metal impurities approach the magnetic field of the magnet block, the metal impurities are finally adsorbed on the magnet block under the action of the attraction force of the magnet block, so the metal impurities in the refrigerating oil can be constantly adsorbed on the magnet block positioned at the edge of the compressor shell 1. The refrigeration oil in the compressor is continuously stirred, the cleanness of the refrigeration oil is continuously improved, the cleanness of the refrigeration oil is ensured, and the operation reliability of the compressor is improved.
The compressor constantly runs, and metallic impurity also can constantly produce, but the existence of adsorption component 3 makes metallic impurity constantly adsorbed on the magnet piece, has guaranteed the cleanness of the inside refrigeration oil in oil bath to further improve the reliability of compressor operation, adsorption component 3's design has prevented the condition that impurity got into the pump body, has reduced the damage of pump body part.
Because the high cleanliness of the refrigeration oil can be kept, the situation that the oil suction pipe sucks metal impurities close to the bottom of the oil pool can be avoided and improved through the short oil suction pipe of the compressor. The metal impurities in the freezing oil pool are continuously adsorbed in the movement, so that the prior freezing oil pool can keep higher cleanliness, therefore, the length of the oil suction pipe is properly increased, the oil suction liquid level of the oil suction pipe is reduced, the injection of redundant freezing oil is reduced, and the purpose of saving cost is further realized. The reduction of impurities in the refrigeration oil can prolong the service life of the pump body, reduce the wear failure rate of the pump body of the compressor and increase the operation reliability of the compressor. After the metal impurities are adsorbed, the length of the oil suction pipe or the height of the cavity can be properly increased, so that the quantity of the refrigerating oil is further reduced, and the production cost is reduced.
The first embodiment is as follows:
the cavity structure is added to the compressor to improve the oil level of the refrigeration oil, so that the reduction of invalid oil quantity is realized, but due to the cavity structure, the distance between the bottom of the refrigeration oil pool and the oil suction nozzle is reduced, and metal impurities gathered at the bottom of the oil pool are easier to enter a pump body part of the compressor through the oil suction nozzle to cause the abrasion or the blockage of the compressor. Therefore, it is important to add a magnet block adsorption structure in the compressor cavity.
The magnet piece is located the cavity structure of lower cover 2, and is located the interior laminating top surface of cavity structure of lower cover 2, can design the magnet piece of laminating compressor housing 1 bottom and 2 cavity structures of lower cover according to the shell ground shape of different compressors, and the direct welding jack catch 4 is fixed the magnet piece in the cavity structure of lower cover 2. The magnet piece still can adsorb the metallic impurity in the oil bath through 2 top surfaces of thin lower cover, guarantees the reliability of compressor operation, because the magnet piece is cyclic annular design, can increase the adsorption of adsorption structure to the metallic impurity in the refrigeration oil through the area that increases the magnet piece magnetic ring, improves the cleanliness of refrigeration oil in the oil bath.
The second embodiment:
as an alternative embodiment of the above embodiment, the magnet block is located on the top surface of the lower cover 2, and the fixing manner of the magnet block is varied on the top surface of the lower cover 2, but considering that the oil suction pipe exists in the center of the oil pool, the edge fixing is reliable, and the clamping claws 4 can be welded on the edge of the magnet block to fix the annular magnet block at the edge position close to the circumference of the compressor housing 1, so that the metal impurities can be adsorbed on the housing edge.
The fixed mode of two kinds of magnet pieces all can carry out fixed rethread three spot welding earlier with lower cover 2 and magnet piece or the mode of colding pressing and carry out the monolithic stationary, the assembly of being convenient for with this structure. And the magnet block is of an annular structure, so that the adsorption strength of the magnet block to metal impurities can be adjusted through the area of the magnetic ring, and the optimal adsorption effect is achieved.
In conclusion, after the ordinary skilled in the art reads the document of the present invention, according to the present invention, the technical solution and technical concept of the present invention do not need creative mental labor to make other various corresponding transformation schemes, which all belong to the protection scope of the present invention.
