柴油机在运转过程中,由于润滑系统的故障而发生机油供应中断的情况是屡见不鲜的。这时,如不及时停车,往往会造成烧瓦,拉缸等严重事故。有些柴油机,虽然装有警报系统,但由于噪声、振动等种种原因,有时仍难于察觉,无法及时停车,致使事故仍不可避免。这里介绍的一种机油失压自动停车装置,可以在机油压力下降到规定时,自动地切断高压油泵的柴油供应,使发动机迅速停车。本装置通过中间接头10(见附图),安装在高压油泵的进油口处。其作用原理如下:起动时,先用
Diesel engine operation, due to lubrication system failure occurred oil supply interruption is not uncommon. At this time, if not parking in time, often resulting in burning tile, pulling cylinder and other serious accidents. Some diesel engines, although equipped with an alarm system, are sometimes still difficult to detect due to noise and vibration and can not be stopped in time, making the accident unavoidable. The oil pressure loss automatic stop device introduced here can automatically cut off the diesel oil supply of the high pressure oil pump when the oil pressure drops to a predetermined value, so that the engine can be stopped quickly. The device through the intermediate connector 10 (see photo), installed in the high-pressure pump inlet. Its principle of action is as follows: When starting, use first
