在工程机械柴油机的运行过程中,当转速确定时,如果机油压力太小,则供油不足,会造成润滑、冷却不良;如果机油压力过大,可能冲破机油滤清器。因此,要对柴油机的机油压力进行实时监测,以减小机器故障概率,提高诊断效率。在实践中,设计了一种基于STP系列压力变送器的柴油机机油压力测量方案,并与单片机监测报警及机器故障诊断技术结合应用,收到了预期的效果。
In the operation of construction machinery diesel engine, when the speed is determined, if the oil pressure is too small, the lack of oil, can cause lubrication, poor cooling; if the oil pressure is too large, may break the oil filter. Therefore, it is necessary to monitor the diesel engine oil pressure in real time to reduce the probability of machine failure and improve the diagnostic efficiency. In practice, a kind of diesel engine oil pressure measurement scheme based on STP series pressure transmitter was designed and used in combination with SCM alarm and machine fault diagnosis technology, and received the expected results.
