Abstract

The invention discloses a sensor for measuring the pressure of a high-pressure oil pipe of a diesel engine, and the sensor comprises two semi-circular fixed frames and a display. The two semi-circularfixed frames are connected with each other through a hinge, and the parts, far from the hinge joint, of the two semi-circular fixed frames are symmetrically provided with fixed plates in a fixed manner. The surfaces of the two fixed plates are connected with fastening bolts through screw hole threads. The surfaces of the two semi-circular fixed frames are connected with positioning bolts throughfour screw hole threads. The ends, stretching into the semi-circular fixed frames, of the positioning bolts are rotatingly connected with an arc-shaped placement plate. One side, far from the positioning bolts, of the arc-shaped placement plate is fixedly provided with a pressure sensor, and the surface of the arc-shaped placement plate is fixedly connected with the inner walls of the two semi-circular fixed frames through two symmetric telescoping rods. The sensor is simple and reasonable in structural design, is convenient to operate, can suitable for oil pipes with different diameters, andsaves the cost.

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...
