How to change frequency control for a 132kw air compressor started in star-delta mode
Thread Content
The downtime is long, the air compressor runs continuously, loading and unloading occur frequently, resulting in high energy consumption. Is it possible to change the frequency control? What would be the cost?
1. Add another frequency converter; domestic ones cost around over 10,000 yuan. 2. If the air compressor controller has frequency control functionality, it can be reconfigured; if it lacks such functionality, then it needs to be replaced, at a cost of around a thousand yuan
It can be completely modified. The ABB ACS800 frequency converter costs around 30,000 yuan; adding the distribution panel brings the total budget to 40,000 yuan.
Do you think it’s appropriate to increase the variable frequency speed control, or is it better to purchase a small air compressor?
Can this motor be speed-controlled using variable frequency?
The model number on the nameplate isn’t very clear; it seems to be YP. If it is indeed YP, then it is a variable-frequency motor.
If it’s modified by the manufacturer, it will be more expensive, but the quality is guaranteed； It’s easy if the factory has technical staff; just buy a larger frequency converter
