Description
Technical Field
The invention relates to the technical field of equipment deformation monitoring, in particular to a three-dimensional expansion measuring device for industrial equipment.
Background
When the industrial equipment deforms beyond the tolerance of the components, it can cause damage to the equipment, breakage, and even unplanned furnace shutdowns. The monitoring demand of industrial equipment expansion is developed from timing monitoring to real-time online monitoring. The real-time continuous monitoring can master the running state of the equipment in real time, and has great significance for the safe running of industrial equipment.
Changes in the geometry of the pressure-bearing equipment or components after exposure to heat and pressure are monitored by industrial equipment expansion indicators, which if outside the design limits indicate a problem with the operation of the equipment. The expansion monitoring of the industrial equipment can timely find the deformation of the evaporation equipment caused by improper ignition, temperature rise and pressure rise, and prevent cracks, leakage and the like caused by uneven expansion.
Taking an industrial boiler as an example, most of the conventional boiler expansion indicators are designed by adding a scale plate on a pointer, and are called as mechanical boiler expansion indicators. The pointer of the mechanical expansion indicator is fixed on the boiler, the field grid scales with millimeters as units are carved on the scale plate, the scale plate is fixed on the boiler steel frame, and the pointer is perpendicular to the scale plate. Because the boiler steelframe is static relatively, and the boiler takes place to expand and contract when the temperature variation, so the volume that takes place relative displacement between pointer and the scale plate is the inflation volume of boiler.
During the start, stop and large load change operation of the boiler, the patrolling personnel go to each monitoring position of the boiler to check the scale value pointed by the pointer of the mechanical boiler expansion indicator on site.
Along with the increase of the boiler volume, expansion measuring points are more and more, the distance between each point position is longer, the manual inspection and recording accuracy and timeliness are poor, the boiler expansion data are not easy to analyze correctly, expansion hidden dangers are found, and the dynamic expansion condition of the boiler cannot be monitored and recorded in real time; and the data of the same inspection is not the data at the same moment, which brings difficulty to hidden danger analysis and increases analysis errors.
Since expansion of industrial equipment often has three expansion directions, for example, in an industrial boiler, the boiler moves in the axial direction of a pointer of a mechanical expansion indicator, in order to avoid contact between the pointer and a scale plate, a certain safety distance needs to be kept between the pointer and the scale plate, and the distance depends on the maximum expansion amount of the boiler in the axial direction of the pointer. This safety distance reduces the reading accuracy and precision of the indicator. In order to improve the precision and reduce the safety distance, the scale plate is horizontally placed, and the pointer is changed into a vertically telescopic pointer. However, the scale of the scale plate is millimeter level, the area of the top end of the pointer is larger than 1 millimeter, and the telescopic design of the pointer makes it more difficult to ensure the accuracy requirement of 1 millimeter after the pointer is telescopic. The error of the mechanical boiler three-way expansion indicator is very large.
Statistical analysis is difficult because all data is recorded on paper version notebooks. When computer-aided analysis is needed, expansion values of the boiler are required to be manually input into a computer, the larger the data volume is, the data entry work is delayed, and once the data is delayed, the reference value is obviously reduced.
Based on the problems, the boiler expansion detector based on the micro-displacement positioning technology is provided. The detector uses the absolute encoder to measure the expansion condition of the boiler, real-time expansion data is displayed through the liquid crystal display and written into the memory card, and meanwhile, the data is sent to the control room through the bus interface, so that accurate and real-time boiler expansion information can be provided for power station operators. However, an encoder configured on the boiler expansion detector based on the micro-displacement positioning technology is a contact sensor, and must be in contact measurement with a monitoring part, so that the structure is complex, and the cost is high; after the data of the inflation monitoring instrument is acquired, manual analysis is still needed, the analysis result is often related to personal experience, and the objectivity is poor.
