What is the reason why the second-stage air compressor VF-9-7 made in Quzhou can't start? Please master the advice!
What do you mean, in detail, why didn't the second stage start and the crankshaft turned to the connecting rod? Why can't it start?
You mean the second stage can't exhaust? Please check whether the exhaust valve group of the second-stage cylinder is damaged, which is caused by the excessive anti-gas load in the cylinder. I work as an air compressor accessory in Chengdu.
