公司有5台LGF-31-18/7-D型移动式螺杆空气压缩机,承担着5台KQ150型潜孔钻机和5台25型手持式风钻的供气任务。螺杆空压机的工作过程分为吸气、压缩、排气三个阶段。在前两个阶段中,润滑油与空气相互混合为油气混合气,润滑油起着润滑、冷却及密封等作用,而在排气阶段,油气混合气通过止逆阀进入油气分离器,润滑油必须在油气分离器中从空气中彻底分离出来,回到油循环系统,而空气流经后冷却器进入的压缩空气管网。我们在使用和维修早期的螺杆空压机过程中,发现其油气分离器存在一些问题,我们进行了如下结构改进,经过多年的使用获得了较好的技术经济效果。
The company has 5 sets of LGF-31-18 / 7-D mobile screw air compressors and undertakes the gas supply tasks of 5 sets of KQ150 DTH drilling rigs and 5 sets of 25 hand-held pneumatic drills. Screw air compressor work process is divided into suction, compression, exhaust three stages. In the first two stages, oil and air mixed with each other as a mixture of oil and gas, lubricating oil plays a lubricating, cooling and sealing role, and in the exhaust phase, the gas mixture through the check valve into the oil separator, lubricating oil Must be completely separated from the air in the oil separator, returned to the oil circulation system, and the air flows through the compressed air pipe after the cooler enters. During the process of using and repairing the early screw air compressor, we found some problems with the oil-air separator. We made the following structural improvements and achieved good technical and economic results after years of use.
