3 Terms and definitions

The terms and definitions defined in GB/T 5849 and LY/T 2071 and the following terms apply to this document.

Blockboard

A wood-based panel composed of wooden strips along the direction of the grain, with two sides glued to the veneer or plywood blank.

Blockboard production During the completion of blockboard processing, the machine is from sliver processing, core molding, core post-processing, blockboard molding and finished product molding.

The combination of bed equipment and supporting system equipment. Generally includes. veneer manufacturing, sawing, drying, thickness-setting processing, glue-splicing, pre-pressing of embryos, hot pressing, Post-processing and other processes.

Key electromotors

Motors with high rated power, high load factor or long-term running in production.

4 Planning and design

4.1 Principle. On the premise of meeting the requirements of production technology, environmental protection, safe production and energy saving and emission reduction, according to the product variety, specifications and Production, etc., through scientific planning and design, the production equipment selection, plant area, pattern, ventilation, lighting, heating, thermal insulation and dust removal systems, Compressed air systems are reasonably matched to achieve scientific production planning and design, low investment, low energy consumption, and economical and reliable operation.

4.2 The overall planning and design of the power supply system, the rationalization of power supply for the enterprise, the rationalization of electrical energy conversion to mechanical energy, and the rationalization of corporate lighting should meet the requirements of GB/T 3485.

4.3 The overall design and layout of the compressed air station shall meet the requirements of GB 50029 and GB 19153.

4.4 The design of pneumatic dust removal (transport) system shall comply with the requirements of LY/T 1806; the basic dust prevention rules and technical requirements for dust prevention shall comply with LY/T Regulations of 1659; Energy saving methods shall comply with the regulations of LY/T 1862.

5 Production equipment selection

5.1 Principle. The selection of production equipment should be compatible with the output, type, specifications, process flow, continuity and degree of automation of the product.
