Abstract

The invention discloses a pressure sensor detection system for a diesel engine, and relates to the technical field of sensor detection. The pressure sensor detection system comprises an air pressure pressurizing part, a measuring cylinder part and a control box part, wherein the air pressure pressurizing part is used for pressurizing a detection cylinder; the measuring cylinder part is a place formounting a pressure sensor to be measured; and the control box part is used for receiving and processing sensor signals and displaying detection results, and is also used for storing detection data.According to the pressure sensor detection system, detection of various pressure sensors can be realized, detection, data storage and analysis of the to-be-detected pressure sensor, judgment of detection results and the like can be automatically completed, the working efficiency is improved, and the cost of detection on a diesel engine rack is reduced.

Description

technical field [0001] The invention relates to the technical field of pressure sensor detection, in particular to a detection device for a pressure sensor of a diesel engine. Background technique [0002] With the upgrading of emission regulations, diesel engines have developed from traditional mechanical control to electronic control systems. A variety of pressure sensors are used in electronically controlled diesel engines. It is necessary to quickly detect and judge the performance of these sensors in the process of development, testing, production, and maintenance of diesel engine products. Due to the huge amount of varieties used (a company's annual usage of millions), traditional detection methods are no longer suitable. There is an urgent need to develop a new detection mode. Therefore, it is particularly important to design a pressure sensor detection device that can be tested quickly and is easy to operate. The existing scheme is to install relevant pressure sen...
