本文介绍一种柴油机防飞车保护装置,它可以在柴油机一旦发生飞车现象时,切断其供油油路,使柴油机停车,而起到保护作用,杜绝飞车现象的发生。 柴油机防飞车保护装置工作原理简述如下: 此装置主体由检测传感部分和计数控制部分组成。检测传感部分由磁铁和霍尔传感器组成。 磁铁是用环氧树脂粘合固定在柴油机的飞轮一侧,其随飞轮每转一周,则影响霍尔元件传感而使传感器产生一个脉冲信号。 霍尔传感器采用SL-3019(仿美史普拉格公司UG-3019),此器件可靠性高,抗干扰能力强,电源适应范围宽,兼容性好。其主要包括稳压器、霍尔电
This paper introduces a diesel anti-speed protection device, which can occur in the event of diesel speed phenomenon, cut off its fuel supply circuit, so that the diesel engine parking, and play a protective effect, to prevent the phenomenon of speeding. Diesel anti-speed protection device operating principle is summarized as follows: This device by the detection of the sensing part of the sensor and the control part of the composition. Sensing part of the detection by the magnet and Hall sensor. The magnet is epoxy resin bonded to the flywheel side of the diesel engine, with each revolution of the flywheel, then affect the Hall element sensing and the sensor generates a pulse signal. Hall sensor SL-3019 (imitation American Prager company UG-3019), this device high reliability, anti-interference ability, wide power adaptability, compatibility. It mainly includes voltage regulator, Hall electricity
