Plate waveform scanning device for plate heat exchanger

Abstract

The invention discloses a plate waveform scanning device for a plate heat exchanger, which is composed of a measurement gantry bracket, a plate fixing mechanism, a ball screw linear walking mechanism, a biaxial servo synchronization system, laser scanning sensors and an Advantech ARK-3440 computer measurement and control system, wherein each laser scanning sensor is installed on a sliding block of the ball screw linear walking mechanism, so that the two laser scanning sensor at both sides of a plate are controlled by the servo system so as to move synchronously, thereby being capable of measuring parameters such as the waveform, the plate thickness and the like at the obverse side and the reverse side of the plate at any positions. The plate waveform scanning device disclosed by the invention is convenient and quick in test, high in detection work efficiency and high in measurement precision, improves the work efficiency of quality detection, strengthens inspection means, and is particularly obvious in efficiency improving for large plates. In addition, the plate waveform scanning device solves a problem of thickness reduction which cannot be directly measured before.

Description

technical field [0001] The invention belongs to the technical field of quality inspection of plate heat exchangers, in particular to a plate wave scanning device for plate heat exchangers. Background technique [0002] The plate heat exchanger is one of the main equipment in the petrochemical industry. The quality inspection methods of its manufacturers are relatively backward. At present, the corrugation depth and thinning are measured manually by using a dial gauge. Relatively low, the data can only be recorded manually, and then entered into the computer for processing and storage, and the work efficiency is low. It is impossible to accurately measure the heat transfer area. Contents of the invention [0003] The purpose of the present invention is to provide a plate heat exchanger plate waveform scanning device that can effectively improve the detection work efficiency and measurement accuracy, and can realize the functions of automatic data display and storage.
