“…So, the sensor can be installed at the end of the shaft to monitor the shaft temperature, thus monitoring the idler surface temperature. Experiments indicate that the fuming temperature of the common belt is around 220~240ºC, the steel-cord belt 250~270ºC and the coal powder is 330ºC~350ºC [7]. On the other hand, since the flash temperature of the machine oil used in mine is 190ºC, the safety regulation for equipments used in coalmine prescript that the machine surface temperature mustn't exceed 150ºC.…”

“…Each time when the roller has rotated one circle or when the belt has moved a certain distance, the Hall effect sensors used to measure the velocity difference will send out a group of pulse signals. And these signals can be collected by the 8098 mainframe through HSI (high-speed input) interfaces and be disposed as has been discussed in part four [7].…”

According to the statistical data offered by US Bureau of Mines, belt conveyor fires account for about 20 percent of the mine fires Technologies on belt conveyor fire-monitoring system have drawn the attention from both scientific research institutions and manufacturing corporations. However, most methods and techniques available for monitoring the belt conveyor fire in mines are still not satisfactory. This paper presents a set of new methods and techniques for monitoring and forecasting the mine belt conveyor fire, and introduces a new practical system which is developed on the basis of them, including the design and installation of transducers, the design of conversion circuits, the design of monitoring and fault diagnosis software. Industrial applications as well as laboratory experiments have proved that this system is characterized by its simplicity in structure, convenience in installation, reliability in performance and strong environment adaptability, etc.

“…The safe and stable operation of the pump is of great significance to energy saving and orderly production 3 , 4 . As a necessary guarantee for the safe and efficient operation of coal mining, the emulsion pump station is required to ensure a stable supply of fluid to the coal mining working face 5 , 6 . It is mainly composed of an emulsion tank, emulsion pump set, and hydraulic control system.…”

Wear is a common issue in the operation of emulsion pumps. When it becomes severe, it can lead to machine downtime and economic losses. This paper aims to investigate the wear phenomenon on the slideway of emulsion pumps using Archard’s wear model and the finite element method. The fretting friction and wear experiment was used to calibrate the parameters of the numerical model. Based on the established numerical model, a parametric analysis is conducted on the slideway experiencing the most severe wear. It is observed that the wear amount initially increases and then decreases as the crankshaft speed increases. Furthermore, a smaller clearance between the slide and the slider results in a reduced wear amount on the slideway. This study presents an effective numerical simulation method for studying the wear of emulsion pumps.

A condition monitoring and fault diagnosis system for heavy duty diesel engines used in off-highway vehicles is developed. Via this system, the vibration, rotating speed or angle, temperature and pressure signals can be collected simultaneously at a high speed. The software is developed using virtual instrument technique. The system provides various types of signal analysis methods, and manual and intelligent diagnosis functions. Its performance is validated in engineering practice. The system can be generalized for monitoring and diagnosis of various reciprocating engines.
