Selection criteria for quality of industrial hanging rails
2020-04-08 15:07:42
Industrial suspension sliding doors originated in Europe and entered the Chinese market in the 1990s. Due to the process, the upper bearing and the lower auxiliary guide structure are adopted. This makes the industrial sliding door abandon the traditional production concept guided by the original bearing. It greatly saves the production cost and greatly reduces the after-sales service troubles caused by the use of traditional products. Improve work efficiency. Because of its characteristics: sturdy and durable, compact structure, beautiful appearance, easy installation, stable operation, easy push-pull and superior wind resistance. Rapidly become the main force in the translational industrial door. Get the affirmation and favor of many door factories, steel structure companies and logistics production line facilities companies!
In recent years, due to the rapid economic development, the construction and development of industrial parks throughout the country, and the demand for steel structure frame plants are also increasing. There are also many manufacturers of industrial door hardware on the market. The competition is fierce! Many manufacturers continue to squeeze costs in pursuit of profit maximization, which makes the quality of hardware products uneven. Many projects due to the lack of relevant technical support and qualified hardware products make the project eventually lead to tragedy to the construction party caused irrecoverable losses! The company has years of experience in operating industrial sliding door hardware products and will list the following when purchasing products. We hope that the manufacturers will be helpful when purchasing and using them.
1. First, talk about hanging rails and the most important carrier for hanging hardware. It not only serves the purpose of load-bearing, but also serves as a guiding slot for the load carrying material. The size and thickness of the track are finalized at the beginning of the design and finalization according to the experimental test and the parameters obtained after actual use. In Europe as a hanging hardware is a strict safety standard. Therefore, the choice of track is to pay attention to whether the actual thickness of the track has tolerances. Some manufacturers will reduce the size of the section or reduce the thickness to achieve the purpose of reducing costs. In addition, the material of the track is also an important evaluation indicator. The material of the track, which is usually used as a bearing, is Q235, and many manufacturers use Q195 materials for processing. Q235 combines plasticity and hardness. Guaranteed the load-bearing strength of the track under load. It is the most commonly used material for load-bearing profiles. The Q195 material cost is relatively cheap. The material is soft and easy to shape and has a low scrap rate. However, it is easily deformed under low load. In the repeated operation of the pulley is also easy to wear! In addition, we must observe the thickness of the orbital zinc layer, and the degree of regularity of the cross-sectional shape can be used as the basis for judging the superior and inferior orbits!
2. The hanging wheel is equally important in the upper load bearing hardware. The final bearing capacity of a series of products is not only to see the strength of the track, only the strength of the hanging wheel also meets the conditions of the bearing. The overall load-bearing capacity can go up. Generally, a good quality suspension frame is generally a high-quality cold plate formed by stamping. It combines toughness and strength. Bearings are load-bearings that are custom-built with long double-row ball bearings. There is a blocker on the outside. Can increase the bite with the frame. The wheel is riveted together with the bearing through the shaft. The material of the screw transitions from the standard rod to the high-strength screw in accordance with the weight from small to large. Inferior suspension wheels are mostly cast iron frames with poor toughness. Extremely easy to crack. Bearings are mostly standard plain bearings. Individuals are small and narrow. They have only single row of balls and do not have the function of bearing weight. It is very easy to damage when the load is running. In addition, in order to save cost, the inferior hanging wheels can find the overall size in comparison with the quality and inferior quality of the same series of products. The thickness of the plates, the diameter of the wheels, and the thickness of the screw are all significantly different. Finally, observe whether the overall riveting of the hanging wheel is regular, whether the thread and the nut are flawed. Whether the galvanized surface is even or not with rust.
3. Mastered the selection of hanging wheels and hanging rails. Then talk about the matching of hardware and doors. Doors of different sizes and weights should be fitted with hanging rails of different load-bearing grades. The upper load-bearing door is subject to factors such as the structure of the building. Weight 2000 kg or less can be used on the load-bearing structure. More than 2,000 kilograms generally take the next load-bearing structure. Many manufacturers have only two or three models of suspension rail hardware. The bearing range is mostly between 100-400 kg. In case of heavy doors, these two products are also used. Increase the load by increasing the number of pulleys and increasing the orbital welding distance. This method is most undesirable. We all know that the load-bearing object is the most evenly weighted and the most stable in its operation. If more pulley weight is added. In actual operation, it is difficult to ensure that the pulley can be subjected to both forces. And the force is not uniform. The pulley with low force not only fails to share the bearing during the operation, but also increases the resistance and noise. Accelerate the damage of the heavily loaded pulley. The correct practice is to replace larger models of hardware with the weight of the load. Generally, the load-bearing of the track increases, and the size (width and height) of the corresponding track section increases accordingly, and the thickness of the track also increases. The same is true for pulleys. The overall frame, the diameter of the wheel, the diameter of the screw, and the bearing of the load will change accordingly. To achieve the standard of bearing! In addition, the load bearing strength of the rail can also be increased by adding rail fixings.
4. In addition, the installation and daily maintenance at the construction site are also critical to the final results, service life, and safety of industrial doors. Door installation should also consider geographical differences, environmental factors, wind resistance, etc.! It can be said that there is a lot of hard work and support from high-quality manufacturers, sellers, builders, and technicians of the upper suspension industrial doors. I hope that the introduction of this article will help you in the future selection and use! For more details and technical guidance, please contact us!
