Technical Field
[0001] The utility model relates to the technical field of gas compressors, in particular to an oil scraper for a gas compressor. Background Art
[0002] Reciprocating compressors are widely used in various fields such as petroleum, chemical industry, natural gas, metallurgy, and gas transportation. The oil scraper is one of the important components of reciprocating compressors. However, the oil scrapers of compressors currently on the market have different states of leakage. Long-term leakage will not only cause high fuel consumption and on-site pollution of the equipment, but may even cause oil and gas to enter the cylinder and have a negative impact on the subsequent working section. At the same time, it can prevent oil from entering the cylinder, thereby keeping the air clean and free of oil. This process is crucial to ensure the normal operation of the compressor and extend its service life. If the oil scraper ring does not work, a large amount of lubricating oil may be carried out by the piston rod, resulting in waste, and water may enter the crankcase, causing the lubricating oil to emulsify and deteriorate, reducing the lubrication performance. Therefore, we need to design an oil scraper for gas compressors. Utility Model Content
