Abstract

The invention relates to the technical field of detection, and discloses an oil content control device for testing refrigeration components, including a first oil separator, a first step-down pressure difference regulating two-way valve, a pressure relief valve, a first oil storage tank, The first oil supplement valve, the second oil supplement valve, the oil supply tank, the pressure supplement valve, the compressor, the second oil separator, the second oil storage tank, the oil level controller, the first lubricating oil pipeline, the refrigerant pipeline, The second step-down pressure difference adjustment two-way valve, condenser, main road flowmeter, oil content adjustment two-way valve, oil flow meter, controller, second lubricating oil pipeline, pressure relief pipeline, pressure supplement pipeline and Pressure piping. The invention provides circulating power for the lubricating oil of the test system through the pressure regulating system, not only effectively achieves the purpose of controlling the oil content of the system, but also is more stable and consumes less energy than other oil content control devices.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to an oil content control device for testing refrigeration components, in particular to an oil content control device based on an oil separation method. Background technique [0002] The current test methods for oil content of refrigeration systems usually include sampling weighing method, light absorption method, sound velocity method, projection method and oil separation method, but most of the existing refrigeration system performance test benches are not equipped with special equipment that can accurately measure and control A device for the lubricating oil circulation rate of the refrigeration system. [0003] Chinese patent CN200910047464.7 discloses a test device for detecting and controlling the circulation rate of lubricating oil in a refrigeration system, which uses two oil separators to completely separate the lubricating oil from the mixture of refrigerant and lubricat...
