由兖州矿务局南屯煤矿和煤科总院南京研究所共同研制、南京研究所试验工厂和江苏泰兴防爆电器厂共同试制的HJJ型水平胶带输送机综合保护装置,于1992年1月18日通过了由兖州矿务局组织的技术鉴定。该综合保护装置具有对皮带低速打滑、跑偏、皮带穿透撕带、温度超限、煤位等项保护,并具有主机拒动、紧急停止与维修闭锁、起动延时、超温自动喷水及声光信号等项性能。设计中采用了集控、保护及显示为一体的新技术,功能比较齐全、线路简单,维修方便。外接口留有余地,有较强的扩展功能,有一定的应用价值。(培娟) By Yanzhou Mining Bureau Nantun Coal Mine and Nanjing Institute jointly developed by the Institute of Nanjing Institute of Test Factory and Taixing Jiangsu explosion-proof electrical plant joint trial of HJJ horizontal tape conveyor integrated protection device, in January 18, 1992 Passed the technical appraisal organized by Yanzhou Mining Bureau. The integrated protection device has the advantages of low speed slippage, deviation, belt penetration tear tape, over temperature limit, coal location and other items of protection, and has the host refused to move, emergency stop and maintenance lock, start delay, over-temperature automatic sprinkler And sound and light signals and other properties. Design used in the control, protection and display as one of the new technology, complete functions, simple lines, easy maintenance. There is room for external interface, a strong extension of the function, there is a certain value of the application. (Pei-Juan)
