Welcome to the official website of Shibo Machinery!
When we use a spiral duct machine, what is the problem of insufficient air volume in the spiral duct machine? It is easy to see the shortage of air volume of the spiral duct machine. Generally, this situation is caused by the wind pressure caused by the constant change of the pressure of the duct machine.
The staff of the spiral duct machine told us that when we use the spiral duct, the flow rate does not change much with the spiral duct opportunity of the pressure change.
However, when we found that the traffic has changed, this is mainly because our spiral duct machine has changed its speed when it is working. It can be seen that the selection range of pressure of the spiral duct machine is relatively wide when it is used, and the choice of the flow rate is mainly determined by the speed of the spiral duct machine during operation.
The early spiral duct machine was used for metallurgy and natural ventilation. In the metallurgical industry, it needs to pass the high temperature test. In order to meet the requirements, the spiral duct machine production technology has been continuously improved, and has a great relationship with the development of metallurgical technology. Operation, spiral duct machine manufacturers here tell you that the spiral duct machine does not need to add lubricating oil during use, so that it will not discharge oily gas when it is used.
