This question was asked by a customer. Let's answer it separately. It can be divided into two situations.
1. If it is an integrated high-pressure blower, use a frequency converter.
Then its rotation speed is constant, the rotation speed under the frequency of 50hz is 2850 rpm, and the rotation speed under the frequency of 60hz is 3400 rpm.
For this kind of blower, the speed can only be adjusted by adjusting the frequency. If the speed changes, the performance of the blower will also change.
2. Pump head, change the diameter of the pulley.
For split-type fans, the pump head without a motor can be driven by a motor belt or a generator diesel engine.
The rotation mode is a belt + pulley mode, if you want to change this speed, it is relatively simple.
The diameter of the pulley can be changed to change its speed. It can be at the pump head or at the motor. The principle is the same.
