Optimization of Compressor Equipment Operation Using Frequency Converters
The power of compressor equipment is largely determined by the maximum productivity, which is achieved only 20% of the time it operates. This leads to significant energy costs, which can be reduced by implementing a frequency converter.
Advantages of Using Frequency Converters
The optimization of compressor equipment operation involves the use of frequency converters that regulate the motor speed. Among the main advantages of their use are:
- Smooth Starting and Stopping – provides gentle operating conditions, which increases the lifespan of the equipment.
- High Speed of Performance Regulation – depends on the load without stopping the equipment and allows for maintaining the specified pressure at the output, reducing electricity costs by at least 50%.
Reasons for Low Utilization of Frequency Converters
There are several reasons why frequency converters have long been underutilized by enterprises:
- High cost;
- Lack of proper technical support during implementation;
- Companies did not guarantee post-warranty or warranty service.
Today, a network of companies has been formed that deals with both the sale and technical support of these devices. The implementation of a frequency converter can pay off in as little as two years.
Differences Between Frequency Converters
All frequency converters have similar power components but differ in the following parameters:
- User interface;
- Programming options;
- Special functions for monitoring and controlling the equipment.
Therefore, when choosing a model, it is necessary to clearly define the list of required functions, as one should not overpay for unnecessary features.
Selecting the Optimal Device
To select the optimal frequency converter, it is important to conduct a complete examination of the equipment on which it is planned to be installed. Proper adjustment of the drive determines the efficiency of the device’s operation.
In doing so, the following features should be considered:
- Specifics of programming the frequency converter, including the ability to identify drive parameters;
- Characteristics of the motor load;
- Response to short-term power outages;
- Internal fault diagnostics;
- Monitoring the operability of external power switching devices.
Choosing a Manufacturer
After analyzing the technical specifications and pricing policies of various manufacturers, a few foreign companies can be highlighted that:
- Offer acceptable products – a wide range of frequency converters for economical and efficient compressor operation;
- Have a developed technical support system for their products.
