Introduction

  Tianyan Machinery Co., Ltd. is a subsidiary of China Chang'an Automobile Group Co., Ltd. Tianyan machinery mainly produces and sells exhaust gas turbochargers, engine intake and exhaust valves, armored vehicles, EMU cooling fans and other engine parts. It is a designated research and production base for national high-tech enterprises, national military turbochargers, cooling fans and other engine parts. The vacuum oil filter purchased by the company is mainly used to deal with unqualified hydraulic oil containing water emulsification and impurities. Due to the long-term use of the hydraulic system, only the filter element inside the system can be used for filtration. The inner filter element has low filtration accuracy, large filter hole clearance, and small impurities cannot be effectively filtered. The failure of the water circulation Series in the hydraulic system causes water to flow into the hydraulic oil, which leads to emulsification. The hydraulic oil vacuum oil filter purchased this time is mainly the equipment for removing water and impurities.
