I have ordered and payed for two ready assembled and tested Diesel powered compressors Type Hongwuhuan W3128 from the Company Quzhou Able Machinery Equipment Co., Ltd.. Both compressors never have been tested for sure. No smell of Diesel in the fuel tanks and both engines were not fixed.
When I unpacked them I have seen immediately that the belts are not tightened and the Diesel engines were not fixed. So I took a compressor mechanic to help me. We found out that it was not possible to tighten the engine bolts as they were stuck to the engine. Our contact told us that we should simply shorten these screws, but said that the compressors had been tested. With not tightened screws ??
After we had aligned the engine according to the operating instructions, and the V-belts were accordingly stretched, the first start took place. After about 30 seconds, the compressor threw off the V-belts. The reason for this was that the engine had moved and was no longer straight. Our guess, the engine mounts are too weak. After consultation with my contact, I was told that probably the engine mounts were too weak. I thought the compressors had been tested. Then I had 4 new engine mounts made. After these were installed and the engine and V-belts were aligned by laser, a new test run. This time the compressor was running for about 2 minutes and only reached a pressure of 5 bar and not, as promised, 7 bar. After 2 minutes the compressor threw off the V-belts again. We also found that the compressor leaked in several places and lost air.
During this test run we noticed extreme vibrations. Presumably imbalance in the flywheel of the compressor. After consultation with my contact, I was told that this is probably due to an imbalance in the flywheel happens. I thought the compressors had been tested? Many more tests followed, but it was not possible to get the compressor working properly. My contact person told me that maybe the V-belts are the problem or maybe the flywheel. He suggested sending me the parts. I said that I ordered and paid for two functioning and checked compressors and no kits. Therefore, I wanted the redemption and repayment. My contact told me that he would immediately take back the compressors if they were in China. However, they are exported and therefore they can not take them back.
There followed more attempts on my part to bring the seller to the refund, but unfortunately unsuccessful.
I brought both compressors last Thursday to a compressor workshop – kaeser representative –
This list of mistakes I got today seems already close to fraud .
– both compressors leak on different positions
– at compressor 1 two cylinder feets are leaking
– at compressor 1 air pipe connection to the head is leaking
– at compressor 1 air pipe leaks on 2 positions
– at compressor 1 head is leaking
– at compressor 2 one cylinder feet is leaking
– at compressor 2 one head is leaking
– at both compressors the flywheel/fan is offset drilled one with 0.16 the other with 0.18 out of center.
– at both compressors the flywheel/fan is out of balance 573gr and 621gr
– both compressors do not reach 0,7mpa – maby it is only an adjustment of the valve, but if they had been tested, they should be adjusted-
– both compressors throw the belts and are not usable
Conclusion of the workshop there : bring it to the junk yard .
This I told my contact. No Answer . Silence. Because I have an insurance with Alibaba for failure and quality defects, I have now reported the case Alibaba and wait for feedback. My contact person at Quzhou Able Machinery Equipment Co., Ltd. does not answer anymore.
