The outdoor LED display project is a comprehensive engineering project. During the entire construction process, it is designed into many disciplines such as electronics, civil engineering, network, and decoration. Therefore, it is very necessary to understand the entire project composition. The following is an introduction to the construction of the LED display installation project that you share to help you understand.
First, the introduction of LED electronic screen installation project
The LED electronic screen project is a comprehensive engineering project integrating electronics, optics, communications, computers, networks, structures, civil engineering, and decoration.
The LED electronic screen installation project belongs to the electromechanical installation project from the equipment point of view, that is, the installation of LED lighting equipment, other related projects are to create a basis for the installation of the display screen, and at the same time to coordinate with the surrounding environment, other related projects Respectively:
1) Civil Engineering Foundation (including lightning protection grounding)
2) Steel framework
3), exterior decoration works
4), strong and weak electrical wiring and ancillary equipment installation
Second, the composition of the LED display installation project
1) Basic introduction of civil engineering foundation
The LED display civil engineering foundation project is the basic project of display screen installation. It is mainly used as the base of the screen in the outdoor display project. Its function is mainly in two aspects (1) carrying the weight of the screen evenly on the foundation, Prevent screen settlement. (2) balance the wind load on the screen body to prevent the screen body from overturning.
The civil engineering foundation is mainly composed of foundation parts, bearing platforms, reinforced concrete foundations, embedded parts and backfill soil.
Reinforced concrete is composed of reinforced keel and concrete. Concrete is uniformly mixed with cement, sand, gravel, and water in a certain proportion. It is also called ç ¼ (TÇ’ng). Rebars resemble bones, and concrete is like flesh, which combines to achieve high strength. As a civil engineering foundation used for display screens, the general duration is from 7 days to 45 days.
The embedded part is embedded in the concrete together with the prefabricated steel structural parts when the concrete is poured. This can provide a solid foundation for the installation of the external components. The commonly used embedded parts include pre-assembled screws and prefabricated steel plates.
Lightning grounding:
Outdoor civil engineering foundations generally require additional lightning protection grounding. The basic approach is to use a certain standard flat steel welded into a grid-like grounding net when groundwork is in progress. The grounding net is buried in the foundation and the foundation soil is made certain Treatment, so that the resistance down to lightning protection and grounding requirements, and then the concrete in the steel with its multi-point welding, and flat steel multi-point out of the ground in order to connect with the structure later, so that the entire component with lightning protection grounding. The measurement of grounding resistance generally uses a grounding resistance meter, and the resistance generally requires less than 10 (ohm).
3) Basic introduction of exterior decoration project
The LED display exterior decoration project is to fix the decoration and decoration material to the outside of the steel structure frame by using structural joints or adhesives, so as to achieve a beautiful and elegant appearance, and achieve protection such as waterproof (for outdoor) and the like.
Introduction of commonly used decorative materials:
Stainless steel: The stainless steel used for general decoration mainly includes matt brushed stainless steel and mirror stainless steel, which can be selected according to customer requirements. Commonly used thicknesses are 0.8mm, 1.0mm, 1.2mm, 1.5mm, etc., and the thickness of the material is generally determined according to the size of the wrapping area.
Aluminum (buckle) plate: Aluminum plate is made of aluminum alloy plate pressed into a fixed size by mechanical means. It is fixed to the steel structure frame by means of coupling pieces. The color can be used in a variety of ways. The disadvantage is that the cost is high, the size needs to be pre-made, the site is not easy change.
Aluminium plastic board: It is a very commonly used decorative material. The structure is to cover the plastic substrate with a thin layer of aluminum. The surface of the exposed paint is protected by fluorocarbon spraying. The advantages are more colors and good weather resistance. Lightweight and easy to make on the spot. Commonly used specifications are indoor panels, outdoor panels; thickness of 3 mm (indoor), 4 mm (outdoor).
Other materials: Other commonly used materials are glass glue, weatherproof sealant, structural sealant, aluminum square tube, wood keel, wood splint, etc. These materials are mainly used as the base plate of the exterior decorative plate, and are sealed and waterproof.
4) Introduction of commonly used LED display installation methods
Because the installation method is difficult to say unity, so the following explanation according to the stress point of the screen structure, LED display is actually a hexahedron, only the front is the display, can not be forced connection, the other five faces can be force connection .
a. Back: The usual way to install using the back is wall hanging, and the whole is fixed on the wall.
b. Top: The usual way to install using the top is lifting.
c. On both sides: Screen mounting, commonly used between two cylinders, with both sides installed.
d. Bottom: Common, stand-alone column supports installed using the bottom, as well as base mounts.
e. Hybrid: There is more than one side of force, usually two or more coordinated forces, and the common method is embedded.
Industrial Pumps
Industrial pumps, refers to the pump used in industrial production.
Industrial pumps are machines that deliver or pressurizes a liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, and increases the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal, and also to transport liquids and gas mixtures. And a liquid containing suspended solids. The technical parameters of the pump performance include flow, suction stroke, lift, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volume pump, vane pump and other types. The volumetric pump uses its change in the volume of the working chamber to transfer energy. The vane pump uses the interaction of the rotating blades and water to transfer energy. There are centrifugal pump, axial flow pump and mixed flow pump.
Pumps have different uses, different liquid media, different flow rates, and different lift ranges. Therefore, its structural form is of course different, and the materials are different. In summary, it can be roughly divided into:
1. Urban water supply 2, sewage system 3, civil engineering, building system 4, agricultural water conservancy system 5, power station system
6. Chemical system 7. Petroleum industry system 8. Mining metallurgical system 9. Light industrial system 10, ship system
