One screw air compressor can save a lot of operating costs compared with several piston air compressors
Some factories and enterprises bought a piston air compressor in consideration of the cost when they were first put into production. Then they bought another one because there was not enough air. In this way, several low-power piston air compressors have been available in the factory over the years. In fact, this seems to save the purchase cost, and virtually increases the electricity and maintenance costs of operation.
There is such a packaging and color printing company. Compressed air is required for their offset printing machines. Before that, they have always used piston compressors. Basically, a set of offset printing machines is equipped with a small piston machine. There are more than a dozen large and small piston air compressors in the whole workshop, including 3KW, 4kw, 5.5kW and 7.5kW.
According to the person in charge of the company's equipment, these small piston machines were OK for a year or two at the beginning. There was no big problem, but after a long time, the trouble came out. Today, the air compressor broke down, and tomorrow, the air compressor broke down again. Almost every once in a while, the piston compressors had to be repaired. The workload of several mechanics was heavy, and the maintenance cost was also high, I heard that there are screw air compressors that can replace these small piston compressors, so I went to Hangzhou Dekai Compressor Co., Ltd. to learn about them.
After visiting their workshop, I found that so many piston compressors have a long service life and serious oil leakage, which greatly affects the working environment; In addition, after observation, I found that the use frequency of these piston machines was not too high, and there was a large margin. Moreover, after I superimposed the motor power of all air compressors, I found that there were nearly 70 kW, while the gas production superimposed on the nameplate was only about 10 cubic meters.
I therefore recommended that the user consider purchasing a screw air compressor with 55kW power and a gas production of 10 cubic meters, laying the main pipeline in the workshop, and then distributing the pipeline to each offset press to realize centralized gas supply. The user also thought that this scheme was feasible, so they adopted it and purchased this set of screw air compressor equipment from our company. After three months of practical application, the user was very satisfied, not only saving power, but also reducing a lot of maintenance costs, In addition, our company also provides a full range of after-sales service. The mechanic of their company basically doesn't need to take care of the air compressor any more. If there is any problem, our after-sales engineer will go there after a phone call. It can be said that replacing the piston compressor with the screw air compressor is really a worry-saving, labor-saving and money saving way.
