Sensor adapter for monitoring internal pressure of diesel engine cylinder

Abstract

The invention discloses a sensor adapter for monitoring the internal pressure of a diesel engine cylinder; the device comprises a screw, and threads are arranged on the outer circumferential surface of the screw; a nut is arranged at the top end of the screw, and the middle of the upper end face of the nut and the bottom end of a cylinder are connected into a whole; through holes are formed in themiddles of the screw, the nut and the cylinder in the axial direction, connecting threads are arranged on the inner walls of the through holes, and pressure sensors are inserted into the through holes; a left temperature sensor mounting hole is formed in the left side of the through hole in the screw rod, the screw cap and the cylinder in the vertical direction, the left temperature sensor mounting hole is a blind hole which does not penetrate through the screw rod, and a left temperature sensor is inserted into a left temperature sensor mounting hole. The invention aims to provide a sensor adapter for monitoring the internal pressure of the cylinder of the diesel engine, which is accurate and reliable in measurement data, good in measurement effect, capable of quickly and accurately evaluating the state of the engine, very convenient to assemble and disassemble and particularly suitable for starting the diesel engine from a main engine starting distribution disc to a cylinder head starting valve by utilizing compressed air.

Description

technical field [0001] The invention relates to a sensor adapter for monitoring the internal pressure of a diesel engine cylinder. Background technique [0002] There is a kind of diesel engine that uses compressed air to start the distribution plate of the main engine and start the cylinder head start valve. The compressed air used to start the diesel engine is generally stored in the air bottle, and the air bottle is connected to the main start valve / air distribution of the diesel engine through a pipeline. On the engine and starting valve, the basic action sequence is the air bottle-open the stop valve-pull the control handle to open the main starting valve-start the distribution valve / starting valve, the starting distribution method controls the opening of the starting valve, and then the compressed air enters the cylinder through the starting valve In the process, instead of high-pressure gas, the piston is pushed down to rotate the crankshaft. [0003] The starting va...
