Kunshan bombings Warning: dust concentration of dust is very important security monitoring and alarm detection alarm easiest-to-use program at 7:35 on August 2 Xu Rong Metal Products Co., Ltd. Kunshan car wheels polishing workshop in the serious explosion has caused to 75 people were killed and 180 injured. After the accident, the responsible person of the enterprise to be controlled to assist the investigation. Preliminary investigations by the accident investigation team determined that the accident was due to someone's business does not solve long-term problems and hazards, dust concentrations exceeding encountered fire source explosion, was a major liability accident. Kunshan plant dust explosion after the accident, the state security department to strictly control excessive dust problems. Shaanxi Star Coal Mine Safety Equipment Co., Ltd. for the actual needs of the market at present dust concentration monitoring alarms, instrumentation technology departments to develop a set of dust detection alarm easiest-to-use program, which the company three explosion-proof products: GCG1000 (A )-type dust concentration sensor, KXB18 type sound and light alarm, KDW127 / 12B Encapsulation and intrinsically safe DC power supply, plus an intrinsically safe junction box components. Program block diagram of the greatest feature of the program is entirely of intrinsic safety explosion-proof product composition, suitable for hazardous environments with explosive dust dust monitoring and alarms. Dust concentration sensor can monitor the environment in real-time dust concentrations encountered excessive dust, sound and light alarm will sound and the red light flashes the alarm, prompting customers to the risk of emergency treatment, to achieve the purpose of disaster prevention. Program configuration list No. Product Name Model Quantity Remarks a dust concentration sensor GCG1000 (A) 1 2 mine safety type sound and light alarm KXB18 1 3 Encapsulation and intrinsically safe DC power KDW127 / 12B 1 4 intrinsically safe junction box JHH- 4 Product Name: GCG1000 (A)-type dust concentration sensor Product Description: The product absorbing the advanced measuring dust technology, supporting various coal mine safety monitoring system, explosive flammable gas mixture continuously detect the presence of environmental Dust floating in concentration. Has a fast and accurate measurement, high sensitivity, local display, remote signal transmission, stable performance, preset K value and other characteristics. Product Name: KXB18 mine safety type sound and light alarm Description: KXB18 mine intrinsically safe alarm sound and light equipment control through to sound and light signal indication underground methane, carbon monoxide and other parameters are exceeded, and switch alarm if abnormal fixed mine of information security instrument for coal mine use in each workplace. Alarm for mining intrinsically safe, reliable, simple structure, easy to use and flexible. Product Name: KDW127 / 12B DC power supply Product Description: The product is encapsulated mine explosion-proof and intrinsically safe structure, charge and discharge and back-up power is switched entirely by the SCM system into intelligent management. Small size, light weight and other characteristics. Applies to the presence of flammable, combustible and explosive gas mixture environment, to provide power for the mine sensors and other intrinsically safe equipment.
