1前言电子技术应用于柴油机测速及自动保护,对于提高测速精度和确保柴油机安全可靠地运转,延长其使用寿命和改善操作人员的工作条件等是一项有效的措施。 135系列柴油机是国内一种多机型的系列产品,它广泛用于农业排灌和工业配套以及船用主、辅机的动力设备。本文主要介绍在135系列柴油机上应用数字式智能转速表既能测量转速又可实现超速自动保护。 2简介 135系列柴油机的转速测量,在原结构中,其直列机(2、4、6缸机)采用501E型机械驱动转速表;V型机采用SZD—1型电动转
1 Preface Electronic technology used in diesel speed and automatic protection, is an effective measure to improve the speed accuracy and to ensure the safe and reliable operation of the diesel engine, to extend its service life and to improve the working conditions of the operator. 135 series diesel engine is a domestic multi-model series of products, which are widely used in agricultural irrigation and drainage and industrial facilities and marine main and auxiliary power equipment. This article mainly introduces the application of digital intelligent tachometer on the 135 series diesel engine to measure the speed as well as realize the over-speed automatic protection. 2 Introduction 135 Series diesel engine speed measurement, in the original structure, its in-line machine (2, 4, and 6 cylinder machine) using 501E-type mechanical drive tachometer; V-type machine with SZD-1-type electric transfer
