Oil-free air compressor is an efficient, reliable and hygienic equipment, widely used in all walks of life. Its control system is the key to ensure the normal operation of the equipment, the following I will give you a detailed introduction to all aspects of the oil-free air compressor control system.
The oil-free air compressor control system consists of four main parts: compressor control, electrical control, stability protection and monitoring system.
First, compressor control
Compressor control is the core of oil-free air compressor control system. It mainly includes compressor start-stop control, pressure regulation control and load/unload control.
1.1 Compressor start-stop control:
The start-stop control of oil-free air compressor is adjusted according to the demand of air source. When the air demand exceeds the set pressure, the control system will start the compressor; When the air supply demand is below the set pressure, the control system will stop the compressor.
1.2 Pressure regulation control:
The pressure regulation control of oil-free air compressor is to maintain the stability of the output pressure. By monitoring the output pressure of the compressor, the control system adjusts the working state of the compressor to keep it within the set pressure range.
1.3 Load/Unload control:
Load/unload control of oil-free air compressors is designed to improve energy efficiency. When the air supply demand is lower than the set load pressure, the control system will switch the compressor to the unloading state, that is, no compressed air is produced; When the air supply demand exceeds the set load pressure, the control system will switch the compressor to the load state, that is, to produce compressed air.
Second, electrical control
Electrical control is another important part of the control system of oil-free air compressor. It mainly includes an electrical control cabinet, an electrical component and a control panel.
2.1 Electrical control cabinet:
Electrical control cabinet is one of the core equipment of oil-free air compressor control system, which integrates various electrical components and circuits to realize the control and protection of the compressor.
2.2 Electrical components:
Electrical components include switches, relays, fuses, contactors, etc., which are connected through various circuits to achieve the control and protection functions of the compressor.
2.3 Control Panel:
The control panel is the interface for the user to interact with the oil-free air compressor. Through the control panel, the user can perform various operations, such as start-stop control, pressure setting, fault troubleshooting, etc.
Third, stability protection
Stability protection is an important part of the control system of oil-free air compressor, which mainly includes overload protection, temperature protection, voltage protection and leakage protection.
3.1 Overload protection:
Overload protection is designed to prevent compressor operation from being overloaded. When the compressor is overloaded, the control system will automatically stop the compressor to protect the stable operation of the equipment.
3.2 Temperature protection:
Temperature protection is to prevent the compressor from being damaged due to overheating. The control system monitors the compressor temperature and automatically stops the compressor to prevent equipment damage when the temperature exceeds the set threshold.
3.3 Voltage protection:
Voltage protection is to protect the stable operation of electrical equipment. When the voltage is too high or too low, the control system automatically stops the compressor to avoid device damage.
3.4 Leakage protection:
Leakage protection is to ensure the user's personal stability. The control system will monitor the leakage of electrical equipment, when leakage occurs, it will automatically cut off the power supply to avoid electric shock accidents.
Four, monitoring system
The monitoring system is a part of the oil-free air compressor control system, which mainly includes pressure monitoring, temperature monitoring, current monitoring and fault alarm functions.
4.1 Pressure monitoring:
The monitoring system will monitor the output pressure of the compressor in real time, and when the pressure exceeds the preset range, it will issue an alarm to remind the user to adjust the equipment status.
4.2 Temperature monitoring:
The monitoring system will monitor the temperature of the compressor, and when the temperature is abnormal, it will issue an alarm to remind the user to check the status of the equipment.
43 Current monitoring:
The monitoring system will monitor the current of the compressor, and when the current is abnormal, it will issue an alarm to remind the user to check the status of the equipment.
4.4 Fault alarm:
The monitoring system automatically detects the running status of the device. When a fault occurs, it sends an alarm through sound, light, or display to remind users to handle the fault in time.
The above is the main content of the oil-free air compressor control system. Through reasonable control and protection, oil-free air compressors can achieve efficient and reliable operation and provide continuous and stable air source for all walks of life.
