The basic structure and working principle of negative pressure weighing room
The basic structure and working principle of negative pressure weighing roomThe negative pressure weighing room mainly includes the weighing room body and the negative pressure room. The weighing room body includes a rear channel and a top channel. A negative pressure fan is installed at the bottom of the rear channel. The rear channel at the front end of the negative pressure fan is equipped with There is a weighing room above the air inlet and the negative pressure fan. An air outlet is provided at the front end of the top channel. A primary filter is provided at the air inlet of the rear channel. A high-efficiency filter is provided at the front end of the top channel. An air volume adjustment plate is provided at the end.The negative pressure weighing chamber adopts a vertical one-way airflow form. The inlet air must first be pre-filtered by a primary filter and a medium filter to remove large dust particles in the airflow and initially purify the air for protection. The function of the fan and high-efficiency filter, the pre-treated air passes through the high-efficiency filter, which greatly enhances the filtration effect. The descending low-pressure airflow flows uniformly throughout the operating area, creating a clean and sterile local environment. In the operating procedures of the negative pressure weighing room, another part of the air passes through the high-efficiency filter on the top side to create a slight negative pressure inside the cover, thereby avoiding cross-contamination between different drugs caused by the leakage of dust. The airflow of the equipment is self-circulating to the room where it is located, and the operation/stop of the negative pressure weighing room will not affect the room pressure difference. Confirm through the airflow organization that the airflow inside the device does not flow to the outside of the device. The negative pressure weighing chamber produced by our Bailun Purification Equipment Manufacturing Co., Ltd. is of reliable quality and favored by the majority of users. Potential users are welcome to come for consultation and negotiation. |
