Abstract

The invention relates to the technical field of control, in particular to a tunnel frequency-changing air compressor unit intelligent power air supply system and construction method. The constructionmethod specifically includes the following eight steps of construction preparation, air supply general distribution, air supply general distribution and function design, power air supply pipeline construction, frequency-changing unit control system distribution, mounting of frequency-changing unit air supply system, unit air supply construction and unit moving and maintenance. Compared with a traditional method, sensors are used for measuring and controlling amount of blast in real time, under the condition of insufficient blast capacity, a PLC control system is used for continuously startinga plurality of air compressors, continuous uninterrupted stepless speed regulation of motors is achieved through the air compressors of an air supply system, and thus amount of blast is continuously changed; and under the situation of sufficient amount of blast, the rotate speeds of the motors are decreased in real time until the multiple air compressors are closed, and energy waste is reduced.

Description

technical field [0001] The design of the present invention relates to the field of control technology, in particular to an intelligent power air supply system of a tunnel frequency conversion air compressor unit and a construction method thereof. Background technique [0002] During tunnel construction, an air compressor is needed to supply air to rock drilling equipment and jetting construction. The air volume of the traditional fan is adjusted manually or by auxiliary machinery by controlling the opening of the gate valve to realize the air volume control. Usually, when the tunnel air supply does not have a frequency converter, an air compressor starts to supply air at full load. If the air volume is insufficient, the second or more air compressors need to be started manually. However, due to changes in working conditions or process adjustments, the rated power of the air compressor is greater than the normal operating power most of the time, and full-load air supply will...
