The scale body is the main component of the weighbridge. Therefore, the requirements of the scale body are very high.
As an essential part of the scale body - the scale platform, choice of materials and performance will directly affect the weighbridge of life, what kind of scale body only for their own use of it? This problem has become one of the key factors in the purchase of the weighbridge. The various weighing platforms produced by each manufacturer are similar. The following is an example of Yajin Weighing Apparatus to analyze the classification and performance of the scale body:
Weighbridge can be divided into: U- shaped steel floor scale, channel steel floor scale, I-beam floor scale, reinforced concrete floor scale (common name cement scale)
　　 1. Comparison of channel steel and U- shaped steel.
Why did Kelida choose U- shaped steel floor scales instead of channel steel scales? Here is the one for you:
　　 1 Let's first talk about the channel steel scale body, which is mainly made of channel steel, and then connected by a horizontal partition, and the bottom is sealed.
　　 U- shaped steel scale body is supported by U- shaped steel at the bottom according to the principle of bridge . There is no sealing plate and there is no mold partition.
In comparison, the same type of scale body, channel steel scale weight in the U- shaped steel scale body. The cost is higher than the U- shaped steel scale. The channel steel body has a sealing plate that acts as a tension, and U- shaped steel does not.
　　 2 From the welding point of view, the U- shaped steel scale is full welded, and the channel steel scale is spot welded. Therefore, the industry believes that U- shaped steel is better than channel steel.
U- shaped steel and channel steel are mainly used in the production of weighbridges on the market. The U -shaped steel structure has become the mainstream in the market. U -shaped steel structures and U- shaped steel floor scales are used in the US, Germany, China and even the world .
　　 3 channel steel belongs to the third generation of weighing instrument products. The channel steel has two supporting beams at the bottom, and the middle is empty, so the supporting performance is worse. Simply speaking, the ratio of steel structure is not very reasonable. The channel steel scale is equal to the piece of steel. But the same tonnage channel steel is heavier than U- shaped steel from the weight of the scale body , this truth.
　　 U-shaped steel, is the fourth generation of industrial scales, scales must do U-shaped steel bending machine is equipped with some equipment. Kelida adopts 600T large double-machine linkage bending machine. The cutting machine has high positioning precision and high speed, and the equipment is advanced in the same industry in the province. If you buy this bending machine in the market, you need more than 600,000 yuan. Therefore , the price of U- shaped steel scale is more expensive than that of channel steel . The steel structure is reasonable, the rigidity is good, the strength is good, and the lateral force is strong. ,long life. The bottom of the U- shaped steel is designed with a bridge structure.
Shanghai Yajin Electronic Technology Co., Ltd. U- shaped steel weighing platform adopts 5-7 U -shaped main beams (designed according to tonnage and table size) to ensure the overall rigidity of the weighing platform, the inner cavity of the weighing platform is completely sealed, and it is not easy to rust. After shot blasting treatment, epoxy zinc-rich primer and acrylic acid marine paint are used. The oil film is thick and has a thickness of 100 microns. It is more resistant to pressure, acid, alkali and corrosion.
　　 2 , I-beam is also called steel beam, is a long strip of steel with a cross-section of I-shaped. The specifications are expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d) , such as " work 160 * 88 * 6" , which means that the waist height is 160 mm, the leg width is 88 mm, and the waist thickness is 6 mm I-beam. The specifications of the I-beam can also be expressed by the model number, which indicates the number of centimeters of the waist height, such as Gong 16# . For I-beams with the same waist height, if there are several different leg widths and waist thicknesses, add abc to the right of the model to distinguish them, such as 32a# 32b# 32c# . I-beam is divided into ordinary I-beam and light I-beam, and the specification of hot-rolled ordinary I-beam is 10-63# . The hot-rolled ordinary I-beams supplied by the supplier and the buyer are 12-55# . I-beam is widely used in various building structures, bridges, vehicles, brackets, machinery, etc.
Since I-beam is used less in the truck scale industry, U- shaped steel and channel steel are mainly used by domestic and foreign counterparts . I will not analyze it in detail here.
　　 3 , reinforced concrete floor scale (common name cement scale) with all electronic platform scales, digital floor scales, analog platform scales, Zui big difference is the difference in the structure of the scale body, the former is reinforced concrete structure, the latter is all steel structure. The meters, junction boxes, and printer sensors used by these weighbridges are basically the same. The working principle and lightning protection facilities are basically the same. The construction of the foundation is the same, and there is no essential difference in function. However, the cement scale is much longer than the all-steel structure in the production cycle, so if you want to use the cement scale as the weighbridge, Zui will negotiate with the manufacturer early to avoid delaying the use of the weighbridge.
Advantages of cement scale: fundamentally solve the problem that the scale body is corroded due to rain, sun, acid and alkali corrosion and structural thermal expansion and contraction during the use of all steel structure weighbridge, the use precision is reduced, the service life is shortened, etc. Corrosion ability, structural stability, self-importance, positioning accuracy, no deformation, maintenance-free
Applicable to industries with high requirements for anti-corrosion functions such as public pound stations, chemical companies, port terminals, and refrigeration industries.
