采购拉力机注意事项
应考虑需要测试材料拉力范围
Consideration should be given to testing the tensile range of materials.
拉力范围的不同,决定了所使用传感器的不同,也就决定了拉力机的结构,但此项对价格的影响不大(门式除外)。对于一般橡胶生产厂家,拉力范围在200公斤。因此一般选用单柱式的比较多。
The different range of pulling force determines the different sensors used and the structure of the pulling machine, but this has little effect on the price (except the door type). For general rubber manufacturers, the tension range is 200 kg. Therefore, the general selection of single column type is more.
与单柱式相对应结构的是门式结构,它是适应比较大的拉力,如500公斤或以上。用在金属材料试验多。速度0.01~500 mm/min左右。
Corresponding to the single-column structure is the portal structure, it is suitable for larger pulling force, such as 500 kg or more. There are many tests for metal materials. The speed is about 0.01~500 mm/min.
注:因橡塑厂家一般都要做延伸力,所以在在选购时一定要加延伸计,这样做出来的产品检验才OK.精度才能达到要求
Note: Because rubber and plastic manufacturers generally have to do elongation, so in the selection and purchase must be added to the elongation meter, so that the product inspection done before OK. Accuracy can meet the requirements.
