挖掘机工作中处于短暂待机时,自动怠速装置可以将发动机转速自动降为怠速,这样既可以减少油耗和噪声,又可以减少发动机及主泵的磨损。还可以简化降速操作。本文介绍XE210B型挖掘机自动怠速原理,并介绍2例故障的排查。一、自动怠速原理XE210B型挖掘机自动怠速装置通过其电控、液压系统实现自动怠速功能。1.电控系统自动怠速控制装置电控系统由自动怠速选择开关2、发动机油门旋钮3、主控制器5、上机压力开关6、下机压力开关7、油门马达8、
Excavator work in a short standby time, the automatic idle device can be automatically reduced to idle engine speed idle, which can reduce fuel consumption and noise, but also can reduce the engine and the main pump wear and tear. You can also ease the speed reduction operation. This article describes the XE210B excavator automatic idle speed principle and describes the troubleshooting of two cases. First, the principle of automatic idle XE210B excavator automatic idle device through its electronic control, hydraulic system to achieve automatic idle function. 1. The electronic control system automatic idle speed control device electronic control system consists of automatic idle select switch 2, the engine throttle knob 3, the main controller 5, on the machine pressure switch 6, the next machine pressure switch 7, the throttle motor 8,
