Manufacturing, construction and acceptance of painting equipment

(1) The manufacturing and construction of coating equipment should be assembled according to the design requirements of the component drawings


(2) The tolerances, shape and position tolerances of the main components of the equipment (such as the flatness tolerance of the surface of the metal parts that affect the water flow, air distribution and work performance, such as the water dissipating plate, water curtain plate and flow equalizing plate) must meet the requirements. Design requirements and compliance with relevant standards (G!B50231-98 General Specifications for Construction and Acceptance of Mechanical Equipment Installation Projects)


(3) The verticality and straightness of profiles and steel structures shall meet the requirements specified in design drawings and relevant standards (GB50250-95 Construction Acceptance Specifications for Structural Engineering)


(4) The disconnection and welding of the copper structure shall be determined according to the quality, and shall be carried out according to the requirements of the design drawings and relevant standards, such as: GB/T985-1988 Basic forms and dimensions of gas welding, manual arc welding and gas shielded welding; GB50235 --1988 Construction and acceptance specifications for various on-site and industrial pipeline welding projects.


(5) Plates and profiles can be spliced ​​if the size of the drawing exceeds the material specification, but it is necessary to ensure that the quality of the connection is not allowed for the panels of the dry room and rattan room. The assembly deviation of the plane should meet the requirements of the drawing or related standard regulation.


(6) The connection between the wall plate and the skeleton in the combustion chamber shall be welded


(7) The transmission mechanism should meet the performance requirements specified in the design. The transmission should be stable without slipping, without abnormal noise, without deviation, and the pneumatic moving parts should not have crawling, jumping and impacting phenomena.


(8) After the steel structure equipment has been inspected and passed the inspection, the surface of the section steel and steel plate to be covered after derusting and painting shall be derusted in advance and the derusting grade, coating type and construction coating thickness shall meet the requirements of the design country. According to the paper requirements, follow GB8923-88 to evaluate the rust removal level, and follow GB1764-79 test method for film thickness. ~40μm or more


The color of the coating film should be consistent with the requirements of the design drawings. The color of rattan coating for pneumatic pipelines should comply with relevant professional regulations. The exterior of the coating equipment and the interior wall should be coated with aluminum powder paint, and the moving parts should be painted with the same yellow and black diagonal stripes. The evaluation of the color and appearance of the coating film shall be carried out according to CB1729--79, and the detection of coating adhesion shall be carried out according to GB1720-79.
