Description

Oil-gas separation end cover for air compressor

Technical Field

The utility model relates to an air compressor machine equipment technical field, in particular to oil-gas separation end cover for air compressor machine.

Background

At present, when compressing gas, some oil is injected simultaneously into the interdental volumes of the compressor, thus forming an oil-gas mixture. In order to ensure the quality of the compressed gas, the oil separator is used to separate the redundant oil from the compressed air, and the separated lubricating oil is recycled. The oil-gas separator is one of the main devices of the oil-injection screw compressor, and has the function of separating oil and gas from an oil-gas mixture formed in compressed air, so that the oil content in the compressed air can be reduced, and separated lubricating oil can be recycled.

In oil-injected screw compressors, a mixture of compressed gas and lubricating oil is formed, wherein the lubricating oil is present in both gas and liquid phase. The gas-phase lubricating oil is formed by gasifying liquid-phase lubricating oil under certain temperature and pressure, but the proportion of gas-phase oil in the gas-oil mixture is small, and the proportion of liquid-phase oil is large. The diameter of most oil drops of the liquid phase oil is more than 1 mu m, and the diameter of a small amount of oil drops is between 0.01 and 1 mu m. Because the flow rate of the oil-gas mixture is not very fast, oil drops are under the action of gravity, and large oil drops fall to the bottom of the oil-gas separator and are recycled through an oil return pipeline; the oil drops with small diameters are suspended in the compressed air for a long time and cannot fall to the bottom of the oil-gas separator under the action of the gravity of the oil drops. The oil-gas separator is used for separating the oil drops from the compressed gas, so that the oil content in the discharged compressed air is within 0.003 per thousand. Therefore, the quality of the oil-gas separator directly influences the quality of the compressed gas discharged by the oil-injected screw compressor.
