What is an aluminum honeycomb panel?

What is aluminum honeycomb panel?　　Aluminum honeycomb panel: it is suitable for civil construction, car and ship decoration, etc. It is the application of aerospace materials in the field of civil construction.　　Aluminum honeycomb panel is mainly made of high quality 3003H24 alloy aluminum plate or 5052AH14 high manganese alloy aluminum plate, the panel thickness of 0.8 ~ 1.5 mm fluorocarbon roller coated board or color-resistant baking paint, color-resistant baking paint in scratch resistance, acid rain corrosion and discoloration and self-cleaning than the PVDF, the bottom thickness of 0.6 ~ 1.0 mm, the total thickness of 25 mm, the core using hexagonal 3003 aluminum honeycomb core, the thickness of aluminum foil is 0.04~0.065~6mm, the side length is 5~6mm, the front and rear skins are shaped by roll forming technology, fully automatic machine folding, the front and rear skins are tightly fitted on the installation side, the whole process is completed in a modern factory, the hot pressing process is used, due to the high thermal conductivity value between the aluminum skins and the honeycomb, the thermal expansion and cold contraction of the internal and external aluminum skins are synchronized; there are holes in the honeycomb skin to allow free flow of gas inside the board; the sliding honeycomb skin has small holes, so that the board The sliding installation buckle system will not cause structural deformation during thermal expansion and contraction, so it can ensure a very high degree of flatness. Adhesive: Adopting two-component polyurethane high-temperature curing adhesive, through high-temperature pressurization, and composite with automated honeycomb panel laminating equipment.

What do you know about how aluminum honeycomb cores are manufactured and installed?

Aluminum Honeycomb Core Manufacturer is a company engaged in the research, development and application of aluminum honeycomb core technology, mainly engaged in the research, development, application and promotion of aluminum honeycomb core structure technology. It provides design, research and development, production, installation, maintenance and other services, and can customize various specifications of aluminum honeycomb core products according to customers' needs. Advantages of Aluminum Honeycomb Core The advantages of aluminum honeycomb core are its light weight, easy construction, high strength, good aging resistance and long service life. Since aluminum honeycomb core has good anti-seismic performance, it has a wide range of applications in building structure.　　Applications of Aluminum Honeycomb Core Aluminum honeycomb core can be used in the construction of industrial parks, such as parking lots, garages, fences, guardrails, roads and so on. In addition, aluminum honeycomb core can also be used in factories, warehouses, shopping malls, office buildings, parks, and other buildings for the decoration of roofs, walls, fences and other components, which can greatly improve the safety and appearance of the building.　　Manufacturing Methods of Aluminum Honeycomb Core There are two main manufacturing methods of aluminum honeycomb core, one is casting and the other is calendering. Casting is a manufacturing method of pouring aluminum alloy liquid into molds for cooling and forming, which has the advantages of high strength, good corrosion resistance, etc. Calendering is a manufacturing method of calendering aluminum alloy into a thin plate, which has the advantages of smooth surface, uniform thickness, strong and good corrosion resistance.

Requirements for the use of four types of centrifugal pumps

The first is the cleaning and inspection requirements of centrifugal pumps. Proper cleaning helps maintain the life of the pump and reduces unnecessary losses. Taking the stainless steel centrifugal pump as an example, the pump cannot be disassembled at will during the warranty period, and only the surface contaminants can be cleared; when the time exceeds the warranty period, the first thing to understand about the stainless steel centrifugal pump is that the end surface of the stainless steel centrifugal pump cannot be scratched or scratched during the cleaning process. Scratches, once washed with clean water, immediately apply lubricating oil on the surface of parts and equipment to ensure that it will not cause rust; the second is that the vertical mid-section of the pump casing cannot be disassembled, and cleaning should be avoided as much as possible; the third is the impeller Components and cooling water pipes must be cleaned. The second is the alignment requirements for stainless steel pipeline pumps. First, it is required that the drive shaft and the pump shaft, the drive shaft and the transmission shaft should be connected in accordance with the regulations. If there is no connection standard during the purchase period, Zhao Zheng must be familiar with the "Mechanical Equipment Installation Engineering Construction and Acceptance General" before. Specifications, and use it as a reference material is strictly required. These alignment requirements are all data generated through repeated experiments, and no one should change them at will.

How to disassemble a centrifugal pump, attention to detail is the key

Have you ever disassembled a single stage centrifugal pump? If you want to disassemble such a huge piece of machinery, you must first have a comprehensive understanding of the centrifugal pump, and be able to know every detail inside. In fact, the single-stage centrifugal pump is different from the horizontal multi-stage centrifugal pump. As a kind of stainless steel centrifugal pump, its internal structure is relatively simple. The following Wenzhou Zhongnai Pump Valve will explain how to disassemble the single-stage centrifugal pump. First, cut off the power supply before disassembly to ensure safety during disassembly. Then close the outlet and inlet valves to isolate the external medium source to ensure the interference of unfamiliar foreign objects. At the same time, open the liquid release valve to release the residual pressure in the pump into the air, so that there is no impurities as much as possible. At this time, you can remove the motor base bolts, separate the motor from the pump body, and the first step of disassembly is successfully completed. The second is the disassembly of the pump body. The single-stage centrifugal pump is not as complicated as the stainless steel chemical centrifugal pump. First, remove the base bolts of the pump body and the fastening bolts of the back cover of the pump, and then remove the pump body. Tap the nut with a hammer to release the rust layer so that the foot bolt can be easily screwed. In addition, when the pump cover fastening bolt is located at the connection between the pump body and the pump cover, the corrosion phenomenon is particularly obvious. Because this position is relatively fragile, it cannot be hit with a hand hammer, but can only be rotated gently, which is difficult to disassemble.

The role of pipeline centrifugal pump and installation skills

The correct installation methods for the pipeline centrifugal pump are as follows, because the working mechanism of the pipeline centrifugal pump is to allow the water or liquid to obtain kinetic energy under the action of centrifugal force through the action of the rapidly rotating impeller. Among them, the main points of the installation technology of the pipeline centrifugal pump are: the determination of the installation height of the pump, the middle distance between the water supply surface and the impeller component is the installation height, and the absolute vacuum height is generally indicated on the pump instruction manual and nameplate. At a standard atmospheric pressure and the water temperature is controlled between 20 and 30 degrees Celsius, the distance between the water surface of the water inlet and the section mouth gives the height of this vacuum, which is determined by experiment. However, the disadvantage of this method is that it does not consider the collocation of the size of the water flow and the suction pipe behind. Therefore, the installation height theoretically needs to deduct the lost energy to obtain the height of the vacuum, and then the remaining value is the real value, which can overcome the problems of terrain height and water absorption height in the actual situation. Otherwise the pressure provided by the pump will not pump the water up.
