With the continuous development of the times, the traditional printing machinery can no longer meet the needs of the printing factory, and the research and utilization of pneumatic devices and electrical components properly solve the problem. From the actual development of the current printing enterprises, the application of pneumatic devices in printing machinery is still not mature. This paper starts with the application of the current starting device in the printing machinery, and explains how to improve the application efficiency. 1, air compressor analysis Normally, the air compressors used in printing machinery and the company parameters need to be controlled in the 6-8 bar area. After the index parameters of the air compressor exhaust volume are clear, the air volume of the air compressor can be clarified for a certain period of time, and the maximum value is estimated. When using the air compressor, the water discharge operation process and the water discharge method must be clearly defined in strict accordance with the provisions in the product instruction manual to prevent the sewage from directly entering the cylinder, which brings hidden danger to the safety of the cylinder. 2, filter pressure reducing valve If you need to use a filter in your printing machine, you must ensure that the filter is always placed vertically and cannot be placed upside down. Secondly, it is necessary to pay attention to the daily maintenance and daily management of the filter. The staff should also clean the solid residue and condensate in the filter at any time to ensure that the residual material in the filter is below the water level of the water deflector. Improve the filtration performance of the filter when it is used. 3, pressure reducing valve device In order to improve the application efficiency of the printing machinery pneumatic device, it is necessary to first use the pressure reducing valve device to provide air pressure adjustment for the pneumatic device. The pressure reducing valve device can accept the air compressor to deliver multiple gases, adjust and process the gas to ensure that the output gas pressure meets the requirements of the printing machinery in terms of parameters.
