How does the weight manufacturer tell you about the shape design of standard weights?
2023-06-05
What is the shape design of the standard weight? Let's follow the staff of the weight manufacturer to take a look!
(1) The design shape of the lock is the shape of our ancient copper lock, which is like a cube with a horizontal bar in the middle, suitable for handling with a crane.
The rectangular design shape requires loading and unloading slots on both sides of the weight, and a transport slot for forklift transportation at the bottom of the weight. The edges and corners of the weights should be smooth, and the surface should not have sharp edges or corners or sand holes to prevent wear and dust accumulation.
Surface condition: In order to improve the corrosion resistance and hardness of the weight, the surface of the weight should be appropriately coated with metal.
Flat weight is suitable for cranes, forklifts, and stacked handling.
Round roller design shape: The middle of the round roller is elliptical, with one head on each side, which can be rolled by two people or moved by a crane.
Cylindrical design shape: Cylindrical shape is our common cylindrical shape. The weight is relatively large, with a lifting lug at the upper end that resembles a lock weight, suitable for crane movement
Tip: Before using the weight, use a cleaning brush and cloth to clean the surface of the weight from dust and other stains@ Do not touch the weight directly with your hands. When using weights, please wear gloves and use tools to clamp the weights@ Before conducting balance testing or weight comparison, it is necessary to maintain the weight at a constant temperature to meet laboratory conditions, otherwise it may affect the test results@ The weight should be stored in the original packaging box after use.
Quality control measures for standard weight data to ensure accurate control of test data;
In the conventional transmission of weight values, it is necessary to clean the weights, have stable environmental conditions, and have qualified quality comparators, standard balances, and other devices. To ensure the accuracy of experimental data, technical operations should be controlled.
Expression form
The operation not only needs to meet the requirements of constant temperature time, but also needs to be carried out by two quality measurement personnel for a long time, and then a complex calculation process needs to be completed. The purpose of weighting is to obtain accurate and accurate quality correction values. The quality correction value of each weight is required to not exceed 1/3 of the uncertainty of the measured weight expansion. If most of the mass correction values of the weight do not correspond and the standard device is in normal working condition, then there must be a problem with the cleanliness of the weight. Before measuring the weights, they should be cleaned one by one, otherwise the surface characteristics of the weights will be altered.
Solution
Wash all test weights again with anhydrous ethanol, especially where the weights have text. After gently brushing with a soft bristle brush, wipe off any remaining liquid on the surface with a silk cloth. After passing the constant temperature time requirement, reweigh and meet the specified requirements.
