Manual balance scale

Manual balance scale is a traditional weighing tool.

1. Manual balance scales are made of materials such as metal or plastic. The principle of manual balance is lever balance, and its force arm and resistance arm are equal, so when the weight of the object acts on the balance, the balance can be maintained. The advantages of manual balance scale are high precision, good stability and convenient use, so it has been widely used in business and laboratory fields.

2. The structure of manual dynamic balance scale is relatively simple, and it usually consists of scale plate, scale beam and weight. The weighing pan is used for placing articles and is generally made of light materials such as metal or plastic. The balance beam is a lever connecting the balance plate and the weight, which is generally made of solid material. The weight is used to adjust the weight, and its weight can be changed to adapt to the weighing of articles with different weights.

3. Manual balance scales are relatively simple to use. First, put the items on the scale, and then adjust the weight position until the balance scale is balanced. If you need to measure the quality of goods, you only need to look at the scale on the weight. At the same time, the manual dynamic balance scale also has the advantages of being easy to carry and maintain.

Attention should be paid to the maintenance of manual dynamic balance scale;

1. cleaning: clean the manual balance scale regularly to avoid dust and dirt accumulation. In particular, the weighing pan and lever parts need to be cleaned frequently. When cleaning, you need to use a dry cloth or brush to avoid using detergents containing chemicals.

2. Drying: Keep the manual balance dry to avoid the influence of moisture or moisture. If the manual balance scale is placed in a humid environment for a long time, it will lead to rust of metal parts and deformation of wood parts. Therefore, the manual balance should be wiped clean before and after use and placed in a dry place.

3. Avoid overloading: The manual balance scale has a certain bearing limit, so don't overload it. If the weight of an article exceeds the bearing capacity of the manual balance scale, the weight will be damaged or the lever will be deformed, thus affecting its accuracy and service life.

4. Adjustment: If the accuracy of the manual balance is found to be declining or unstable, it can be adjusted. Its accuracy can usually be restored by adjusting the weight of the weight or the position of the lever. If the adjustment is ineffective, it may be necessary to replace new parts or carry out more detailed maintenance.

5. Storage: The manual balance scale should be stored in a dry and ventilated place after use to avoid direct sunlight or high temperature environment. At the same time, it should be avoided to put the manual day flat in an environment containing chemicals to avoid damage.
