DRCK-01 Emulsion Pumpstation

The Mining Flame-proof and Intrinsically Safe Measuring and Controlling Instrument for Emulsion Pump StationThe proper applied scope of DRCK-01 Series Mining Flame-proof and Intrinsically Safe Measuring and Controlling Instrument for Emulsion Pump Station. Mine-used measuring and controlling instrument for emulsion pump station of flameproof and intrinsically safe apply to coal mines where mixed with gas and other explosive gases, however a surrounding medium shall not include destructive metal and insulated activity chemical substance.Working conditions of safety device Altitude above sea level≤2000 meters The temperature of the media ≤+40°C The relative humidity of the atmosphere≤95%(+25°C)This machine can control the relevant parameter of pump station, such as working temperature,pressure,differential pressure and liquid level. It will be adjusted explosion-proof inverter automatically through the PID with pressure transducer collected pressure signal samples. It is realized full-automatic control of pump system and fluid supplied by constant voltage variable flow, which will stop wasting energy.Sensor of measuring and controlling instrument display,intelligent judge forecast the relevant parameter of emulsion pump station and checking alarm signa. The measuring and controlling instrument automatically execute turn off the power of the pump and shift the electromagnetic unloading valve electromagnetic confecting solution valve.The device is equipped automatic supplement and proportion functions.For the convenience of the customers examination, the protect device store the history information of alert parameter and correspondence time. The authorized users are enabled on-the-spot parameters interactive modifying and alert information historical checking.Measuring and controlling instrument is preserved remote communication interface.It has features of time management alternative, shutdown selection and other subordinate function.Measuring and controlling instrument Duty type: long-term duty Explosion-proof type,flameproof and intrinsically safe. Logo,Exd[ib]ISignificance 1. According to many actual performance test shows, the economy power effect is over 50% in the coal mine. 2. It can keep abreast of the latest development and supervision of pumping station. There has been a decrease in unnecessary faults, maintenance time and safety accidents 3. The unloading valve services the have been cut back drastically with greater durability against breakage. The cost of the labor and maintenance greatly diminished. 4. It is the basic of the hydraulic system to run correctly and stably and to eliminate pulsation impact phenomenon. Not only reduce the accident of tube explosion and increase the safety performance but also save the high pressure rubber pipe cost and expenses of materials. 5. According to the pressure condition, pump station frequency and mechanism friction is decreased which results in savings of maintenance and overhead cost. It has the potential for considerable savings prolong maintenance cycle. The Low Energy Consumption, High Efficiency manner fit entirety policy of enterprise. Technical Specifications 1. The power input,underground workplace of coal mine alternating currents 1140V or 660V, frequency 50 Hz, voltage range of 75%-110% 2. The power output, intrinsically safe circuit 24V, powering sensors, the maximum output current of 510mA. Non-intrinsically safe circuit 24V, the maximum output current of 5A. 3. Protection methods: Non-intrinsically safe circuit 24V and 220Vdouble fuses, liquid crystal display device self fuses, CPU module own overload protection.
