RTC Series Overpressure Automatic Control Device
The RTC series overpressure automatic control devices are primarily designed for use in the petroleum, geology and mining, and exploration industries, as well as in large pumping stations—such as drilling mud pumps, cementing pumps, and downhole fracturing pumps—where high-pressure operation is required. These devices not only provide direct on-site indication of pump operating pressure but also automatically regulate overpressure, thereby ensuring safe production. They are essential safety equipment for all types of high-pressure pumps.
Features:
1. Features reliable automatic control functionality.
2. Convenient adjustment function: the control pressure can be freely adjusted across the entire measurement range to meet the safety pressure requirements of various pumps.
3. The entire device exhibits excellent seismic performance, as the seismic electrical contact pressure gauge used in the system is a fork-spring-type seismic gauge equipped with an electrical contact assembly. This design not only withstands environmental vibration and severe pulsations in the process medium but also tolerates sudden pressure relief.
4. Because the electrical circuit employs a self-holding configuration, it operates stably and reliably: as soon as the pointer makes contact with the contacts, the circuit immediately generates an electrical signal, and vibrations will not cause the signal to be interrupted.
5. The design is structurally sound, easy to install, and features rapid reset: when the set pressure is exceeded, the high-pressure pump immediately shuts down; pressing the reset button manually instantly restarts the pump.
6. Uses a low-voltage DC power supply, ensuring safety and reliability.
Technical Specifications:
1. Pressure range of the electrical contact mud pressure gauge: 40 MPa, 60 MPa, 100 MPa, 120 MPa, 160 MPa.
2. Temperature range: -40°C to +55°C.
- Circuit operating supply voltage: DC 12 V, 24 V.
- Operating current ≤ 2 A.
- Operating air pressure: 0.4–1 MPa.
- The input voltage for the regulated power supply is AC 220 V, ±10%.
- Connection threads: ZG 1½, ZG ¼.
China’s instrumentation industry is poised to seize numerous opportunities. The rapid development of new energy sources such as wind power, nuclear power, and solar energy; the expansion of the Internet of Things, smart grids, and high-speed and urban rail transit; and the growing emphasis on energy conservation, emission reduction, and low-carbon development are all driving broader applications and stronger market demand for instrumentation. Concurrent with advances in microelectronics, computing, networking, and communications technologies, the intelligentization of instrumentation has become the dominant trend. Accordingly, during the 12th Five-Year Plan period, China will prioritize the development of smart instrumentation, strive to penetrate high-end markets, and elevate the overall level of the industry.
