Abstract

The invention discloses a sensor for measuring the pressure of a high-pressure fuel pipe of a diesel engine. A fixed plate is fixed symmetrically, the surfaces of the two fixed plates are threaded with fastening bolts through screw holes, and the surfaces of the two semicircular fixed frames are evenly threaded with positioning bolts through four screw holes. One end of the bolt extending into the semicircular fixed frame is rotatably connected with an arc-shaped placement plate, and the side of the arc-shaped placement plate away from the positioning bolt is fixed with a pressure sensor. The surface of the arc-shaped placement plate is stretched by two symmetrically arranged The rod is fixedly connected with the inner wall of the semicircular fixed frame. The structure design of the invention is simple and reasonable, the operation is convenient, and oil pipes with different diameters can be applied to save costs.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to a sensor for measuring the pressure of a high-pressure oil pipe of a diesel engine. Background technique [0002] High-pressure oil pipes for diesel engines are cold-drawn seamless steel pipes used to manufacture high-pressure pipes for diesel engine injection systems. It is usually made of thick-walled pipes, 6X2 pipes, made of 20# steel or 45#, etc. Formed by upsetting and fitted with fastening nuts. In addition, it needs to be shaped, the head needs to be quenched, and the interior needs to be sandblasted, etc. The highest pressure can reach more than 80MPA. [0003] When the pressure detection of the high-pressure oil pipe of the diesel engine is carried out, the oil pipe is often detected in all directions through the annular pressure sensor, so that under the action of the high-pressure pulse, the slight deformation of the oil pipe can be sensed in time, and throu...
