Abstract

The dedicated lubricating system is used to supply lubricants for large equipments in metallurgical industry. The traditional lubrication system easily leads to lubrication failure for unreasonable design and poor management. A new lubrication system adopting distributed architecture is introduced in this paper. In distributed lubrication system, parameters of oil pressure, flow and temperature are detected to ensure reliable and accurate lubrication for each point. The methods of parameter detection are discussed in detail. The pressure relays are replaced by pressure sensors and accurate pressure control is realized. The control of lubrication volume based on the length of time is changed to accurate control based on the flow of the lubricants. The flow data can be obtained through analyzing the pulses from the three flow sensors installed parallelly on the main pipe. One-wire intelligent digital temperature sensor DS18B20 is used to measure the temperature of the lubrication point. The detection methods have been successfully applied in the lubricating terminal and the lubrication performance has been greatly improved.

分布式润滑系统压力、流量和温度的检测研究

专用润滑系统用于冶金工业大型设备的润滑供应。传统的润滑系统由于设计不合理和管理不善，容易导致润滑失效。本文介绍了一种采用分布式结构的新型润滑系统。分布式润滑系统通过对油压、流量、温度等参数的检测，保证了各点润滑的可靠性和准确性。详细讨论了参数检测的方法。用压力传感器代替压力继电器，实现了精确的压力控制。将基于时间长度的润滑量控制转变为基于润滑油流量的精确控制。通过分析并联安装在主管道上的三个流量传感器的脉冲，可以得到流量数据。采用单线式智能数字温度传感器DS18B20测量润滑点温度。该检测方法已成功应用于润滑终端，大大提高了润滑性能。
