Jeep Compass Air Conditioning Compressor

Good morning!, I would like to know if someone can guide me in what happened to me, I broke the compressor of the air and as I had a arrangement I had to buy one I bought the Chinese because the original is $ 28,000 that seemed a bit expensive, in short the question is that it is already the 3rd compressor that I put and breaks it changed all condenser, filter, cigarette valve but I continue to break the first 2 Of days the last one broke when they were loading gas after doing hydraulic test with nitrogen and emptying!
Well I hope if someone has an idea, I would appreciate them!
Greetings
