The standardised design of the whole machine warning signs and labelling marks is mainly carried out, containing the following aspects.
(1) Warning signs
Marking of all warning locations in the small air separation unit, such as high temperature and high pressure gas warning, gas venting warning, electrical warning, grounding warning, wearing parts replacement warning, etc.
①Warning signs for the overall operation of small air separation units.
② small air separation unit local features warning signs
(2) Marking signs
Uniform design of all types of signs for small air separation units, including gas flow direction signs, process flow signs, key component signs, electrical control wiring number signs, equipment signs, process flow diagram signs, etc.
①Gas flow direction marking
②Key component marking
Each component of small air separation equipment, such as air compressor, cold dryer, gas storage tank, adsorption tower yard gas outlet, etc., is sprayed with the appropriate proportion of marking, and the "Small Air Separation Unit Model Icon Management Measures" and "Small Air Separation Unit Nameplate Management Measures" are designed and compiled to further standardize the marking system of small air separation units.
③Electrical control wiring number marking
All the wire numbers in the electric control box are marked with machine-punched wire numbers, and the "Small air separation unit control box wiring process guideline" is compiled.
④Process flow diagram
Refined design process flow diagrams can be plastic sealed and posted in the control cabinet internal easy to observe place, also can be reflected in the touch screen.
DEAR Design & Research Institute forms research clusters to share resources, complement each other's strengths, improve the efficiency and effectiveness of research projects, and realise the integration of research management and resource clustering.
