Abstract

The invention relates to an injector spray angle automatic detection method based on PLC and a relative device, which spray quality is represented by the working characteristic parameters as droplet size distribution, spray angle and flux density. The device comprises a spray height H detecting system and an effective spray distance L detecting system, wherein the spray height H detecting system comprises serially connected a computer, a PLC single chip, a step motor driver, an injector and a displacement sensor, while a step motor is connected with the step motor driver and a LCD display unit is connected with the PLC single chip, the effective spray distance L detecting system comprises serially connected a displacement sensor, a signal processor, an amplifier, an A / D converter and a PLC single chip, while the LCD display unit is connected with the PLC single chip, displacement sensor and computer in turn. The invention utilizes the combination method of triangle method and water accumulation vessel method and utilizes the pressure sensor with high accuracy to measure the spray force, with small step and the application for automatically measuring injector spray angle accurately.

Description

technical field [0001] The invention relates to a PLC-based nozzle spray angle automatic detection method and device, in particular to an automatic detection method for industrial nozzle spray angles, and its atomization quality is characterized by working characteristic parameters such as droplet size distribution, atomization angle, and flow density distribution. , belonging to the field of advanced testing equipment. Background technique [0002] Industrial nozzles are widely used in metallurgy, steel, petrochemical, pharmaceutical, environmental protection and many other fields. For example, in the metallurgical industry, nozzles are key components of secondary cooling devices in continuous steel casting systems. The cooling quality has an important influence. The atomization angle of the nozzle determines the atomization quality and directly affects its use effect and performance. At present, there are mainly three methods for measuring the spray angle of nozzles, name...
