Design points of weighing room
Design points of weighing room(I) Spatial layoutThe spatial layout of the weighing room is crucial. The principle of one-way flow of materials and personnel should be followed to avoid cross-flow and backflow. Reasonably divide the work area, material storage area, and channel to ensure a smooth operation process. For example, in the design of the weighing room of a pharmaceutical factory, the raw material storage area, weighing room, and finished product area should be clearly distinguished and closely connected to reduce the distance and time of material handling. At the same time, the convenience of operation should be considered, and sufficient space for operators to move should be reserved to avoid crowding and collision. (II) Temperature and humidity control Temperature and humidity control is an important part of weighing room design. According to different usage scenarios and process requirements, determine the appropriate temperature and humidity range. Generally speaking, for weighing operations with higher precision requirements, such as the use of analytical balances, stricter temperature and humidity control is required. If the operating area is larger than 3 square meters and is used continuously for more than 3 hours, cooling control should be considered. Common cooling methods include water coil cooling and air cooling. The specific selection should be considered comprehensively based on actual conditions and cost factors. (III) Air purification system The air purification system is the core of ensuring the cleanliness of the weighing room. Usually, a combination of primary, medium, and high-efficiency filters is used to ensure that the air entering the working area meets the required cleanliness standards. The integrity test of the high-efficiency filter is essential and can be performed by configuring the DOP detection port. In addition, the design of the wind speed is also very critical. It is generally required to be consistent with other laminar flows, that is, 0.45m/s±20%. It can be designed to be manually or automatically adjustable according to actual conditions, and equipped with a wind speed sensor for real-time monitoring. At the same time, attention should be paid to the selection and configuration of the fan to ensure that it can provide stable air volume and pressure, and can promptly alarm and display fault information when the fan is abnormal. |
