The speed of the blower is too fast, how to reduce the speed

This question was asked by a customer. The following are divided into two main answers.

1. If it is an integrated high-pressure blower, a frequency converter is used.

Then its speed is constant, the speed at a frequency of 50hz is 2850 rpm, and the speed at 60hz is 3400 rpm.

For this type of blower, its speed can only be adjusted by adjusting the frequency. If the speed is changed, the performance of the blower will also change.

Second, the pump head, change the diameter of the pulley.

For split-type fans, those without motors are pump heads, which can be driven by motor belts or generator diesel engines.

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 changed at the pump head or at the motor. The principle is the same.

These are the two ways to change the fan.
