KHP belt integrated protection device, belt comprehensive protection, KHP159 intelligent belt comprehensive security devices, KHP128-K Integrated security system conveyor integrated protection device main technical parameters 1 Rated input voltage: AC127V, 50Hz. 2 Enter the apparent power of not more than: 22VA. 3 input signals (intrinsically safe): 4-way passive switch, 4-way active switch; 4 output signal (not intrinsically safe): 2-way passive contact type switch signal, when the contact is closed, the closing resistance of less than 0.5 Ω. 5 safe DC output 1, parameters in Table 1. Table 1 Item specifications of the DC power supply output voltage (dc.V): 11 ~ 12 DC power supply rated output current (mA): 700 overcurrent protection setting value (mA): ≤1400 maximum open circuit voltage (dc.V): ≤12 maximum short circuit current (mA): ≤400 6 Intrinsically safe parameters: Maximum input voltage Um: 140V maximum output voltage Uo: 12.0V; maximum output current Io: 1.4A; maximum external inductance Lo: 0.1mH; Maximum external capacitance Co: 29μF. 7 host with LED indicates fault information. 8 includes a speech signal alarm, loudness not less than 85dB (A). 9 features a) the host has to start, stop, centralized control / manual stop, RBI five buttons. b) the host has deviation, stop, smoke, temperature, the heap of coal, tearing, speed fault signal input. c) host with a belt starting and stopping of the relay contact output (signal access from the belt electrically controlled stop circuit). Contact closure belt during normal operation, fault output contacts open. d) the host can display the belt running, and there is failure to stop indication. e) the host has no material delay parking function: Connect "GTC40-360 no material delay parking sensors," the host into the manual mode, it can achieve along the coal stream of coal immediately alert driving, no coal flow along the coal casting automatic stopping. f) the host has started warning function, start warning time 8 ± 2s. g) the host has centralized control, manual features: 1. Can be achieved through the "control mode" button on the panel to convert, click the button, the top indicator light compared with centralized control, or manual operation. 2. Manual control mode: it starts and stops by from the car and stop button control panel of the table, tap the Start button, the panel will issue a "first X-stage belt will be from the car, pay attention to safety," the speech signal through delay, the belt started running. When the need to stop, press the stop button. 3. Centralized control mode: it starts by the reception host control, the host will issue "on the X-stage belt will be from the car, pay attention to safety," the speech signal, after a brief delay, the transfer belt began shipment. When the need to stop, press the stop button. h) host with a fault alarm and self-locking function: 1. When there is deviation, stop, the heap of coal, tearing, smoke fault signal input, the host can provide the appropriate language of the alarm and the corresponding fault LED indicator, at the same time belt, the stop output relay contact opens. 2. When the temperature fault signal input, the host can provide the appropriate language of the alarm and the corresponding fault LED indicator, while watering relay output, while from the belt, stopping off relay contact output. 3. When the conveyor speed in the 10s were (50% -70%) within Ve (Ve rated speed) range, or belt speed ≤50% Ve, or belt speed ≥110% Ve, the host can provide language corresponding fault alarm and the corresponding LED indicator, while belt, the stop output relay contacts open, the normal starting and stopping of the conveyor speed changes caused by the host no protective action. 4. fault alarm belt is stopped, press the stop button to release the locked state, the failure to stop the belt before receiving the start signal and restart. Centralized control mode when in control, must switch to manual control mode to lift the lock failure. i) host with a communication function RBI: contact with each other when needed, by pressing the button on the machine RBI, RBI issued a signal to inform the other party. Structure 1 Host by flameproof chamber and the chamber composed of intrinsically safe, intrinsically safe to perform an internal power supply, intrinsically safe control unit, the display operation unit and a variety of intrinsically safe sensor. 2 Power execution unit is flameproof and intrinsically safe type, shape is rectangular, left for the power to introduce and export control contact relay; the right to automatic over-temperature sprinklers export control point; the upper right of 12V / 1A intrinsically safe power supply and control signal into lead export; explosion cavity from the power board and transformer. 3 safe control unit: intrinsically safe enclosure has eight sides and outlet, were installed intrinsically safe emergency stop switch, speed, temperature, the heap of coal, deviation, smoke, tear and other sensors and communication with centralized control cable leads line, bottom right panel display lamp provided with a communications transmitter, the left speaker playback with the panel speed, smoke, deviation, the heap of coal, over-temperature, tearing, emergency stop fault mounted state, and operation control button. These two units as a single entity, consisting of the protection device host. The products are widely used in various industries power plants, mines, quarries, chemicals, electric power, to provide protection for safe production. Denway Jining Mining Equipment Co., Ltd. is located in Jining City, Shandong Province, Tang Industrial Park, new and old customers call to plant inspection.
