Precision C profile steel for high-quality equipment is connected by steel structural components

Precision C profile steel for high-quality equipment is connected by steel structural components: 1. After the steel structure factory is installed, it is not allowed to change its structure without permission. It is not allowed to remove any bolts and other components.c profile steel supplier, It is not possible to increase or decrease the partition wall. If you want to change the part, you must negotiate with the manufacturer. After using the steel structure for about 3 years, you must use paint to maintain it once, so that the building can be beautiful and safe. The steel structure workshop is connected by steel structural components, so it is isolated in the use of electrical equipment, such as wire and wire, to avoid electric shock. 2. Precision C-shaped steel for high-quality equipment must be cleaned and maintained regularly. Under normal circumstances, it needs to be inspected and maintained once a year. When cleaning the outer wall of a steel structure factory, it is necessary to take care not to have the following phenomena.

Precision C profile steel for high-quality equipment is connected by steel structural components

You cannot use steel balls, plate brushes, etc., which have abrasive cleaning products. When using clean water, it should be washed from top to bottom. Branches, leaves and other similar objects on the steel structure workshop should be cleaned up in time to avoid unnecessary troubles caused by backlog. If the surface of the metal structure of the steel structure factory is damaged, it should be repaired in time to avoid the sun and rain from corroding the metal surface. If necessary, all the high-elastic nano-materials are used to protect the metal roof panels, and it has an effective heat insulation and waterproofing effect, saving indoor air-conditioning energy.

Precision C-shaped steel for high-quality equipment is a steel-based structure and is one of the main types of building structures. C-shaped steel is characterized by high strength, light weight, good overall rigidity and strong deformation ability. Therefore, it is especially suitable for building large-span and super-high and super-heavy buildings. The material uniformity and isotropy are good, which is ideal elasticity. Body, in line with the basic assumptions of general engineering mechanics; material plasticity, good toughness, can have large deformation, can withstand dynamic load well; construction period is short; its industrialization is high, it can be highly mechanized production. Steel structures should be studied for high-strength steels, which greatly increase the strength of the yield point; in addition, new types of steels, such as H-beams (also known as wide-flange steels) and T-shaped steels and profiled steel sheets, are required to accommodate large-span structures and The need for super high-rise buildings.

Precision C-beams for high-quality equipment are the structural methods used in many architectural designs today. In the traditional construction of our country, because the demand for people has not been met, the steel structure began to appear in front of us. Compared with high-rise reinforced concrete structures, high-rise steel structure engineering is generally soft, and the lateral displacement value under wind load and earthquake is large. If the building has large swing or twist under the action of gusts, it will be The feeling of the human body has a great influence, which often makes people feel uncomfortable and sometimes unbearable. The human body is sensitive to wind vibration acceleration. Steel Profile suppliers

In order to ensure that the high-rise steel structural engineering building has a good working and living environment under the action of wind, it needs Limit the acceleration parallel to the wind load direction and the direction perpendicular to the wind load. When the lateral deformation of a building under wind load or multiple earthquakes is too large, it will cause damage to the building decoration materials and damage of non-structural members, resulting in residual deformation in the steel structural engineering components. In the case of earthquakes, if the deformation of the steel structure works, it will cause great effects, and the serious damage of the non-structural components will also cause personal injury.

Like other cold-formed steels, the problem faced in the production of C-shaped steel is the problem of internal stress. Due to the large internal stress of the material, once it is put into use, it may be deformed, which may affect its use. Where do these stresses come from? The stress of cold-formed C-shaped steel cannot be avoided. In the process of unwinding, rolling shearing, and closing of cold-formed C-shaped steel, certain internal stresses are added, mainly due to mechanical forcing deformation. Cold-formed C-section steel has a certain stress. In addition, if the precision C-beam is not sprayed with a primer, the rust and passivation process will also release its internal stress, causing bending and twisting. In the absence of any way to avoid, the stress can only be reduced by reasonable operation. As manufacturers and users, it is also necessary to focus on this issue to ensure that cold-formed C-section steel can be widely used.

 

Zinc plating is an inexpensive way to extend the life of steel products

Zinc plating is an inexpensive way to extend the life of steel products. It is more economical to consider galvanizing existing stocks than buying more specialty metals. However, hot dip galvanizing is not an ideal choice for every project.Galvanized Steel Pipes for Sales

Zinc plating does not protect steel and steel parts that are often exposed to corrosive materials such as acid and acid rain. The acid can chemically react with the zinc coating. This reaction is particularly harmful in the food industry. Also, galvanizing is not suitable for nuts and bolts that are US “or smaller” because the zinc coating will cause the threads to overflow and thus reduce product strength. In both cases, stainless steel is a better choice.

Zinc plating is an inexpensive way to extend the life of steel products

There are other restrictions on galvanizing. A salt water environment, salt water and prolonged exposure to the weather will shorten the life of the galvanizing barrier. In these cases, the life of galvanized steel is much shorter than that of galvanized steel used in milder environments.

In general, galvanized steel is a sensible alternative to high-priced metals such as stainless steel and aluminum. They have good corrosion protection and provide the necessary strength for a variety of heavy engineering applications.

The galvanized steel pipe is a carbon steel pipe coated with a zinc protective layer. The zinc layer acts as a sacrificial layer, which basically means that the zinc layer will rust before the carbon steel below it. The galvanized layer enhances the corrosion resistance of the steel tube. Zinc is used because the first material to be finally corroded is zinc rather than steel. The zinc layer prevents corrosion and extends the life of the steel tube.

Galvanized steel pipes have many different users in daily engineering. The most common use of galvanized steel pipes is in the construction of awnings, balconies and fences. It is used in electronics, computer housings and many precision instruments. Cars and aircraft pass through the hood, oil sump, parking brakes and roofs are a large number of consumers of galvanized steel.spiral welded steel pipe

Increase benefit:

Low initial cost – galvanizing processes are generally less expensive than other commonly used steels. This is because other steel methods are usually labor intensive. Galvanizing requires less labor, which makes it immune to increased costs

Long service life – Galvanized steel pipes can be used in many rural areas for more than 50 years and in exposed areas for more than 25 years.

Toughness – The initial coating makes the steel very strong and the product is damaged during transport

Quick assembly – Once the steel product is produced, no preparation or painting is required.

If the photovoltaic power station has a significant drop in power generation or other abnormal conditions after the hail, the owner must notify the factory after-sales personnel to conduct the test.

3.heavy rain

If the roof of the PV power plant is installed as a sloping roof, there is basically no need to worry about the rainstorm. If it is a flat roof, it is best to consider the drainage problem when designing and installing the PV power station. When the rainfall is too large, the installation of the flat roof is relatively low, so that the PV modules are soaked by rain. In addition, during the inspection after the rain, do not directly touch the connection between the inverter, the PV module and the power supply cable by hand, and wear rubber gloves and rubber boots to prevent accidents.

4.smog

In the case of plum rain or smog weather and low solar radiation, if the operating voltage of the photovoltaic system does not reach the starting voltage of the inverter, the photovoltaic system will not work. Since the grid-connected power generation system is connected to the grid, when the photovoltaic power generation system is unable to operate, the grid’s electricity will be automatically replenished, so there is no shortage of power and power outage in the rainy weather and smog.

When inspecting a photovoltaic module, the thermal imaging portion is generally used to lock the heat generating portion, or the disconnection detector is used to check the disconnection portion and the bypass diode failure. If the power generation is significantly reduced or other abnormal conditions occur after the component is smashed, the user should promptly notify the operation and maintenance personnel to check the PV system, and if necessary, return it to the original factory for testing, so as to replace the damaged PV module in time.z profile steel

What can be done to build a photovoltaic system power station to ensure stable power generation and weather resistance?

1.Do the early design of the power station: When designing the photovoltaic power station, you need to choose a suitable location. For example, if the photovoltaic power station is built on the roof, it should be considered that the roof fixed load, wind pressure load, snow pressure load, and seismic load are generally “Building Structure Load Specification”, because this is the only way to avoid damage to the power station due to rain and rain.

2.do the installation work: the installation can not be arbitrary, the installation process of the power station should be southward, so that it can fully accept the sun’s light. The installation angle is theoretically equal to or close to the local latitude, and the arrangement and spacing need to be combined with the local sunshine and roof structure dimensions. In addition, we must choose good equipment to effectively extend the life of photovoltaic power plants.

All in all, in order to stabilize the photovoltaic power station in the continuous bad weather, it is necessary to design according to the design, installation and selection, in order to prevent the damage of the photovoltaic power station, and let the power station easily pass the season of frequent rain. Steady operation and security.
