v. control valves, check valves, flexible rubber pipe joints and pressure gauges should be set on the discharge pipeline of submersible sewage pumps. Gate valves are recommended for control valves in the national building standard design atlas s selection and installation of small submersible sewage pumps, This specification is formulated to ensure the construction quality of panel and cabinet devices and secondary circuit wiring installation works, promote the improvement of engineering construction technology level, and ensure the safe operation of panel and cabinet devices and secondary circuits. This specification is applicable to the construction and acceptance of all kinds of switchboard protection panels, control panels, cabinets, complete sets of cabinets, etc. and secondary circuit wiring installation works. The installation works of panel and cabinet devices and secondary circuit wiring should be constructed according to the approved design, During the handling and installation of panels and cabinets, safety measures such as shockproof and moisture-proof measures should be taken to prevent frame deformation and paint damage. If necessary, the installation equipment and vulnerable components can be removed for separate packaging and transportation. When the product has special requirements, it should also meet the requirements of the technical document that the product should inspect the mechanical operation. The panels and cabinets should be stored indoors or in a dry place that can avoid rain, snow, wind, sunshine, frequency conversion control cabinet sand, For the integrated equipment and electrical components of Yantai DCS system with special storage requirements, the equipment and apparatus used shall be stored according to the regulations. They must be qualified products that meet the current national technical standards and have qualification certificates

the equipment shall have nameplates. After the equipment and apparatus arrive at the site, they shall be subject to acceptance inspection within the specified period and shall meet the following requirements: first, the packaging and sealing shall be good; second, the model and specification of unpacking inspection shall meet the design requirements, the equipment shall be free of damage, the accessories and spare parts shall be complete; third, the technical documents of the product shall be complete; fourth, the appearance inspection shall be qualified according to the requirements of this specification, and the safety technical measures during construction, It shall comply with the provisions of this specification and the current relevant national safety technical standards and product technical documents. The construction of construction works related to the installation of panel and cabinet devices and secondary circuit wiring shall meet the following requirements: the construction quality of buildings and structures related to the installation of panel and cabinet devices and secondary circuit wiring shall comply with the relevant provisions of the current national construction and acceptance specifications, When the equipment or design has special requirements

it should still meet its requirements. II. Before the installation of the equipment, the construction works should meet the following conditions: the roof slab construction is completed, and no leakage is allowed; There is no ponding and sundries in the ditch of the studio after the indoor ground is completed; The embedded parts and reserved holes shall meet the design requirements, and the embedded parts shall be firm; Doors and windows are installed; When carrying out decoration work, it is possible to damage the installed equipment or the teeth that cannot be constructed after the installation of the equipment. The decoration work is all over. Three pairs of equipment with special requirements should have the following conditions before installation and commissioning: all decoration work is completed and cleaned; If special facilities such as air conditioning or ventilation devices are installed, they should be installed and put into operation. After the construction of secondary circuit wiring is completed, safety technical measures should be taken to prevent the damage of weak current equipment when testing insulation. After the installation and commissioning of control cabinet, the reserved holes and cable orifices in the building should be blocked, and the construction and acceptance of panels and cabinets should be done

in addition to the provisions of this specification, it should also comply with the provisions of the current national standards and specifications.
