Abstract

The invention provides an air pre-heater gap measuring device and method. The measuring device comprises a detection device and a control device, the detection device comprises a gap measurement module, an extension arm module and a communication transmission module, the gap measurement module is fixed on the extension arm module, and the communication module is connected with the gap measurement module; the control device comprises an intelligent terminal with a communication module, and the intelligent terminal is connected with the communication transmission module. The detection device sends a gap value signal to the control device, data are displayed and recorded through the control device, and the gap measurement work of the air pre-heater is completed. The measuring device has the beneficial effects that for an air pre-heater and other limited spaces which are extremely narrow and difficult to measure manually, key values of gaps can be meausred rapidly, accurately, conveniently and safely, and safe and reliable operation of equipment can be ensured.

Description

technical field [0001] The invention relates to the technical field of mechanical instruments, in particular to an air preheater clearance measuring device and a measuring method. Background technique [0002] The air preheater, also referred to as the air preheater for short, is a preheating device that improves the heat exchange performance of the boiler and reduces heat loss. It is to conduct the heat carried in the flue gas discharged from the flue at the tail of the boiler to the air before entering the boiler through the heat sink, and preheat the air to a certain temperature. The air preheater is a confined space with a small internal space, and it is almost impossible for personnel to move. When personnel measure key clearance data, they often need to dismantle equipment and drill into small spaces for measurement, which is extremely dangerous. Contents of the invention [0003] The purpose of the present invention is to provide an air preheater gap measurement d...
