Problems solved by technology
In the actual welding process, the solder joints of the filter screen cover are often tilted, resulting in the blockage of the oil return hole, and the lubricating oil cannot return to the compressor, so the compressor is burned due to lack of oil after running for a period of time
At present, the inspection method of the oil return hole generally adopts dissection observation. After the dissection, the gas-liquid separator cannot be used again, and can only be scrapped. The process is cumbersome and the inspection efficiency is low.

A method for detecting an oil return hole of a gas-liquid separator is applied to technical field of air conditioners and comprises the following steps: injecting refrigerant oil into a gas-liquid separator to be detected, wherein the refrigerant oil covers an oil return hole of the gas-liquid separator to be detected; using a gas outlet pipe of the gas-liquid separator to be detected to pump outthe refrigerant oil in the gas-liquid separator to be detected; detecting the flow of the refrigerant oil when the refrigerant oil flows through the gas outlet pipe of the gas-liquid separator to be detected; and judging whether the oil return hole of the gas-liquid separator to be detected is blocked or not based on the flow of the refrigerant oil pumped out by the gas outlet pipe of the gas-liquid separator to be detected and a pre-measured standard flow, wherein the standard flow is the flow of the refrigerant oil pumped out by the gas outlet pipe of the gas-liquid separator to be detectedwhen the oil return hole of the gas-liquid separator to be detected is not blocked. The invention further discloses a device for detecting the oil return hole of the gas-liquid separator. The liquid separation capacity of a factory-fresh air conditioner gas-liquid separator can be guaranteed without dissecting the gas-liquid separator, and the detection efficiency of the oil return hole of the gas-liquid separator is improved.
Description
technical field [0001] The present application relates to the technical field of air conditioning, in particular to a detection method and device for an oil return hole of a gas-liquid separator. Background technique [0002] The gas-liquid separator is installed on the return air line of the compressor to separate the gas from the liquid and prevent the liquid refrigerant from flowing into the compressor and causing the compressor to slam. The separated liquid refrigerant and compressor lubricating oil settle at the bottom of the gas-liquid separator. In order to ensure the normal operation of the compressor, it is necessary to return the lubricating oil to the compressor. [0003] At present, in the gas-liquid separator, the oil return hole is installed at the bottom of the gas outlet pipe, and a filter screen cover is welded on the surface of the oil return hole to filter impurities. In the actual welding process, the solder joints of the filter screen cover are often ti...
