Product Description: The mining multi turn intrinsic safety actuator is a valve specific control product designed by our company for the national Class I explosion-proof industry. It is a new generation of intelligent non-invasive product independently developed to meet the needs of different fields based on the absorption of domestic and foreign technologies. It is a control product that integrates multiple automatic control technologies and manufacturing technologies such as multi turn encoder technology, programmable microcontroller technology, infrared remote control technology, LCD display, magnetic switch, etc.
Mining multi turn intrinsic safety actuatorIt is mainly suitable for use with valves that perform linear motion on opening and closing components, such as gate valves, globe valves, water distribution valves, etc. When combined with a gearbox, it can control butterfly valves, air doors, ball valves, etc. It is used to open, close, and adjust valves, and is a driving device for valves to achieve remote control, centralized control, and self-control. It has the characteristics of comprehensive functionality, reliable performance, control system *, small size, light weight, and easy use and maintenance.
Mining multi turn intrinsic safety actuatorpower supply voltageAC660V or AC380V, with control modes including ordinary coal safety explosion-proof switch type, intelligent integrated mining electric switch type, intelligent integrated mining electric regulation type, intelligent integrated mining electric RS-485 bus type, intrinsic safety intelligent integrated mining electric switch type, intrinsic safety intelligent integrated mining electric regulation type, etc. It can accept various control modes such as switch signal, 4-20mA DC analog signal, bus protocol, etc.
1. Conventional coal safety explosion-proof switch type
The opening, closing, and stopping of the control valve can only be controlled by the switch signal given by external control devices such as the control box and PLC system. At the same time, the electric device can only provide feedback on the switch signal to a remote location. In addition to the cost of the control box, the overall cost price for customers to purchase this type is much higher than that of the intelligent integrated one;
2. Intelligent integrated switch type
Without the need for external control devices such as control boxes, valves can be electrically operated to open, close, and stop on the electric device. It can also accept remote switch signal control and provide feedback of switch and analog 4-20mA DC signals to a remote location. However, it cannot accept analog signal control such as 4-20mA DC;
3. Intelligent integrated adjustment type
Without the need for external control devices such as control boxes, the valve can be electrically operated to open, close, and stop on the electric device. It can also accept analog 4-20mA DC control, adjust pipeline flow in real-time, and provide feedback on analog 4-20mA DC at the same time
Send the switch signal to a distant location.
