When choosing a fan, there are many types of fans. If you don’t know the customer, it’s easy to be confused. I don’t know which type to choose and which one can meet my situation. Just compare the two models mentioned today; high-pressure fan and low-pressure fan. Fan.
There is a fundamental difference between the high-pressure fan and the low-pressure fan. From the surface, it can be seen that the pressure of the high-pressure fan is definitely very high, while the pressure of the low-pressure fan is very low and cannot be used in high-pressure places.
The high-pressure fan and the low-pressure fan have the same working mode in terms of operating principle. They are both equipment that converts kinetic energy into potential energy. It uses a high-speed rotating impeller for gas as a medium-pressure fan and completes the entire operation process. .
Just comparing the low-pressure fan with the high-pressure fan, first of all, there is a difference in structure, that is, the difference in the fan impeller. We all know that the high-pressure fan uses an annular impeller, while the low-pressure fan is the impeller of a centrifugal fan.
Although the pressure of the high-pressure fan is much greater than that of the low-pressure fan, the flow of the low-pressure fan is much larger than that of the high-pressure fan, usually more than ten times, which is a very special place. And the pressure is more than ten times smaller.
The latter is the difference in actual use. Because the high-pressure fan cannot pass the material from the fan, it is only suitable for gas transportation in various industries; while the high-pressure centrifugal fan can pass the material, which is a small particle object, so it is used to exhaust air, Dust removal, etc. can be effective.
So how to distinguish?
In fact, it is very easy. First, look at the parameter properties of the label and look at the pressure parameter.
The second is to look at the style, the low-pressure fan, the overall size is very large, especially the pump body, the diameter is very large, so the air volume will be large.
