Reciprocating compressor issues
Thread Content
Which manufacturers produce reciprocating compressors in China? We use those produced by Shenyang Yuanda; they are hydrogen compressors with an outlet pressure of 22.5 MPa, as well as raw gas compressors with an outlet pressure of 4.0 MPa. There are many problems now – could it be that the quality is poor?
We’re also from Shenyang Yuanda; the quality can’t be said to be bad, nor can it be said to be good – anyway, the price is that much
Use the smaller one for everyday use; keep the larger one for Thomson, if the price is acceptable!
One must first consider it from a usage perspective – whether it is being operated correctly and maintained properly, etc.! I heard that the Yuanda models are quite good; we use Wuxi compressors!
If it is oil-free lubricated, problems are likely to occur with the packing, piston rings, and valves. Regardless of where it’s produced.
I’ve encountered several new hydrogen compressors for hydrocracking units that are all K6101A
We have six units with lubrication and two units without oil lubrication; both are from Faraday. During the testing phase, various problems arose to varying degrees in all of them.
Is it a Japanese compressor? Is it reciprocating?
The Farada reciprocating compressors in China are quite good. Reciprocating compressors already have many vulnerable components and various parts that can fail, and oil-free lubrication adds to these problems. If oil-lubricated options are available, try to avoid those that are oil-free. Our unit has 2 oil-powered units in Japan that produce hydrogen, and they have very few problems. The three units of the Yuan Da model are oil-free, and they often experience problems, mainly due to wear of the support rings, wear of the packing, and damage to the air valves.
Whose is K6101A? Is it Japanese? It’s from a manufacturer
The reciprocating machines of some devices must be equipped with oil-free lubrication, as gases cannot carry oil. Oil-free compressors have a surprisingly high number of problems. I’ve seen Thomson’s machines; they have excellent quality and design, but they are a bit expensive. You don’t need to have too high expectations for domestic devices; you get what you pay for
