VSD Screw Air Compressor Control System

Starting Modes
In addition to variable frequency starter, Success Engine VSD screw air compressor series are all equipped with standby industrial frequency starting function. Thus, the air compressor can be shifted to standard industrial frequency operation in case of the malfunction of frequency inverter, ensuring the continuous operation.


Control Modes in the VSD Screw Air Compressor Control System
There are four control modes in the VSD screw air compressor control system: automatic control, manual control, linkage control, and remote control.


Linkage control function is the standard configuration for our VSD screw air compressor control system. With a built-in 485 port, the control system requires no additional linkage-controller. Through simple wire connection, it is able to achieve linkage control of two or more screw air compressors. The VSD screw air compressor control system can automatically start or stop the standby air compressors according to the pipeline pressure. Periodically, it switches the operation between the main compressor and standby compressors, so as to allow them work alternatively. Meanwhile, when there is a failure in the main compressor, the VSD screw air compressor control system will stop it and allows the standby compressor to work. The control system allows for linkage control of 16 air compressors at a time.


Remote control function is the selective configuration for the VSD screw air compressor control system. With the function, the control system can monitor the power consumption and the load/unload situation. It can pre-set and display all the parameters according to the actual air demand. In addition, the VSD screw air compressor control system offers history record checking and displays maintenance alarm.

PLC Controller with Chinese/English Menu
The operation menu makes the compressor control direct and easy. Our VSD screw air compressor control system offers operation status display function. It can offer real time display of the power supply status, exhaust pressure, exhaust temperature, and standard time. An automatic malfunction alarm will sound in case of overheating, lack of oil, over pressure, separator block, oil filter block, air filter element block, lack of phase and phase reverse, motor overload, sensor failure, etc. Also, the VSD screw air compressor control system can be used for parameter presetting and adjustment. To illustrate, it can be used for preset or adjust the control modes, automatic start/stop control, pressure increase or decrease, temperature limits, working sequence of multiple compressors, maintenance time and calendar time, etc. the VSD screw air compressor control system also has history record function, so users can find the history of load/unload running time, oil filter left time, separator left time, air filter left time, total running time, and failure records.

As a China-based VSD screw air compressor manufacturer, SUCCESS ENGINE also offers portable diesel air compressor, air compressor station, stationary screw air compressor, air filter, and much more.
