矿山常用的3L、4L、5L型空压机的冷却器,因承受振动及气压作用,常产生散热铜管与钢管板开焊裂缝,造成漏气,大大降低中间冷却效果,又影响空压机效率。冷却器组件每套价值1000元以上,有修复再用之必要。我们在修理冷却器组件的实践中,曾采用环氧树脂粘结、锡焊、涨管等方法。其中以锡焊 Commonly used mine mine 3L, 4L, 5L air compressor cooler, due to bear the role of vibration and pressure, often produce heat pipe brass and steel plate welding cracks, resulting in leakage, greatly reducing the cooling effect, but also affect the air compressor effectiveness. Cooler components worth more than 1,000 yuan each, there is the need to repair and reuse. In the practice of repairing cooler components, we used epoxy bonding, soldering, pipe expansion and other methods. Among them, soldering
