Early warning device aiming at diesel engine fuel oil leakage flow

Abstract

The invention discloses an early warning device aiming at the diesel engine fuel oil leakage flow. The early warning device comprises an oil outlet valve seat, an oil outlet valve and an oil outlet valve holder, wherein the oil outlet valve is elastically and movably arranged on the oil outlet valve seat; a holding cavity is arranged in the oil outlet valve holder; the first end of the oil outletvalve holder sleeves on the oil outlet valve seat; a high-pressure oil outlet pipe is externally connected to the second end of the oil outlet valve holder; a sealing gasket is arranged at the connecting part of the oil outlet valve holder and the oil outlet valve seat; a drainage mechanism is arranged on the periphery of sealing gasket; a first channel leading out perpendicularly and outwards isarranged on the drainage mechanism and is communicated with the outside space of the sealing gasket; an air inlet mechanism communicated with the first channel is arranged on the bottom part of the first channel; a signal generation device and a signal detector are arranged on the outer side of the first channel. The early warning device aiming at the diesel engine fuel oil leakage flow provided by the invention solves the technical problem that diesel engine fuel oil leakage cannot be effectively early-warned.

Description

technical field [0001] The invention relates to the technical field of diesel engine failure early warning, in particular to an early warning device for diesel engine fuel leakage flow. Background technique [0002] The basic structure of a diesel engine: it consists of cylinders, pistons, cylinder heads, intake valves, exhaust valves, piston pins, connecting rods, crankshafts, bearings and flywheels. The diesel engine of the diesel generator is generally a single-cylinder or multi-cylinder four-stroke diesel engine. Below I will only talk about the basic working principle of the single-cylinder four-stroke diesel engine: the starting of the diesel engine is to turn the crankshaft of the diesel engine by manpower or other power so that the piston is sealed at the top of the cylinder. Make up and down reciprocating motion. The piston completes four strokes in motion: intake stroke, compression stroke, combustion and power (expansion) stroke and exhaust stroke. When the pist...
