Why should Dereike ring blower adopts soft start instead of direct start

2022-03-03 16:20

There are three main reasons why the ring blower adopts soft start instead of direct start:


1. Direct start will cause large start current, small start torque and long start time, which will cause great harm to the motor and power grid
2. Direct start will make the temperature too high, heating speed too fast, temperature gradient and electromagnetic force too large, and shorten the stator

 
There are many points to be paid attention to in the design of high-pressure ring blower.
1. The air temperature of blower changes. When the air flow is close to the closed state, the temperature will rise sharply, so we should pay special attention to the occurrence of this situation. If the temperature will rise, do not use the blower in the airtight room
2. Hard objects, dust, powder, fiber and the time interval of centrifugal ring blower with start stop time interval is generally 3 minutes



However, there are few centrifugal ring blowers with the setting of this summary start stop time interval. Most of the start stop time intervals of centrifugal ring blowers are controlled by the corresponding main control panel, rather than the ring blower itself.

 
Low pressure and high pressure are determined by the area of your plant and the location you want to supply air. Low pressure ring blower P ≤ 980pa, medium pressure ring blower 980pa < p ≤ 2942pa, high pressure ring blower 2942pa < p ≤ 147100pa. This is the basic efficiency of low and medium pressure centrifugal ring blower. The air volume is also related to the air inlet, axial power rate and ring blower speed. If it is applied in the warehouse, it should be based on the warehouse's
