Description

Liquid storage device of compressor

Technical Field

The utility model belongs to refrigeration accessory field especially relates to a compressor reservoir.

Background

The liquid accumulator is an important part of the compressor, plays roles of storage, gas-liquid separation, filtration, noise reduction and refrigerant buffering, and consists of a cylinder BODY (BODY), an air inlet PIPE (INLET PIPE), an air OUTLET PIPE (OUTLET PIPE), a filter SCREEN (SCREEN) and other parts. The liquid storage device comprises a liquid storage device barrel, and an air inlet pipe and an air outlet pipe which are combined on the liquid storage device barrel and communicated with the interior of the liquid storage device barrel. In the operation of the air conditioning system, the refrigerant can not be completely vaporized, namely, the refrigerant coming out of the evaporator can have liquid refrigerant to enter the liquid accumulator, the liquid refrigerant without vaporization can directly fall on the bottom of the liquid accumulator cylinder because the refrigerant is heavier than gas, and the vaporized refrigerant enters the compressor from the outlet of the liquid accumulator, so that the liquid impact caused by the liquid refrigerant sucked by the compressor is prevented. The reservoir part is in the use operation, in order to avoid the impurity in the pipeline directly to get into the compressor, so can install the filter screen between reservoir intake pipe to outlet duct, prevented the possibility that impurity got into the compressor. The compressor runs for a long time, certain lubricating oil is discharged along with vaporized refrigerant in the compressor, and can enter the liquid storage device cylinder through a pipeline, and because the air outlet pipe welded at the bottom of the liquid storage device cylinder is provided with an oil return hole, the lubricating oil precipitated at the bottom of the cylinder acts as force through the suction force of the compressor, and the air outlet pipe returning to the liquid storage device enters the compressor again, so that the compressor is lubricated and protected.

When the compressor is in operation, periodic vibration in the axial direction can occur, the weakest part of the compressor is a welding part, and in order to ensure that a refrigerant does not leak, the liquid accumulator must have good welding quality, particularly at the connection part of the air inlet pipe and the air outlet pipe with the liquid accumulator body.

Generally, the air inlet pipe and the air outlet pipe are both made of copper pipes, the copper pipes are soft, the mechanical strength and the welding performance are good, but the price of the copper pipes is high, in order to save cost, the air inlet pipe and the air outlet pipe can be made of iron or steel, and the problem of welding between dissimilar materials is solved.

The patent with publication number "CN 105234515A" discloses a welding process of suction and exhaust pipes of a liquid storage device, wherein a sleeve is arranged at the joint of a small steel pipe and a copper bent pipe and clamped at a through hole of the liquid storage device, and the welding process comprises the following steps: pre-treatment of welding, including polishing and cleaning; assembling parts, namely clamping the end parts of the small steel pipe and the copper bent pipe in the sleeve respectively to form a welding part; welding is carried out; and clamping the sleeve of the welding part at the through hole of the liquid storage device for welding. The process is beneficial to reducing the hidden danger of leakage of the welding interface, and the leakage rate is greatly reduced to about a few PPM. However, the technical scheme still has the defects of low welding quality and difficult control of the welding process.
