洁净实验室有哪些压差检测方法?

来源:http://www.sdrunjing.com/ 日期:2020-04-28 发布人:润静小编
  洁净室压差测试的目的是验证已完成的设施与周围环境以及设施内部空间之间保持规定压差的能力。本试验适用于空、静、动洁净室入住状态,项目完成后需要定期进行压差试验。
  The purpose of the clean room differential pressure test is to verify the ability of the completed facility to maintain the specified differential pressure between the surrounding environment and the internal space of the facility. This test is applicable to the occupancy status of air, static and dynamic clean rooms. After the completion of the project, the differential pressure test shall be carried out regularly.
  洁净室设计、规划、安装完成后,洁净室的压差是否按设计方案设定?如何检测洁净室的pa值?什么是科学的检测方法?是否有对权威的测试(解释:对权力的自愿服从和支持)?肖斌认为,即使是更落后的压降传感器技术,当压差传感器和气闸室用于级配洁净室时,也能达到良好的保护效果。FFU的优点:结构简单,系统建设成本低,易扩建洁净室,在一些特殊的地方,可以用洁净台来提高洁净室的水平。
  After the design, planning and installation of the clean room are completed, is the pressure difference of the clean room set according to the design scheme? How to detect the PA value of the clean room? What is the scientific detection method? Is there a test of authority (explanation: voluntary obedience and support to power)? Xiao bin believes that even the most backward pressure drop sensor technology can be achieved when the pressure difference sensor and airlock are used in the graded clean room Good protection effect. Advantages of FFU: simple structure, low cost of system construction, easy to expand the clean room, in some special places, can use the clean table to improve the level of clean room.
  一、无尘车间工程压力试验方法有哪些?建议采用以下两种测量方法来检测无尘车间的压力关系:
  1、 What are the engineering pressure test methods for dust-free workshop? It is recommended to use the following two measurement methods to test the pressure relationship of dust-free workshop:
  1. 无尘车间-是的-无尘车间
  1. Dust free Workshop - yes - dust free workshop
  2. 无尘车间对公众的参考点
  2. Reference point of dust free workshop to the public
  需要记录较大压力差的大型制药厂通常使用公共参考点法,这种方法可使压力传感器的数量更小化,并使多次读数的综合误差更小化。压降变送器(通常;高;一侧的一个端口连接到被监控的洁净室,另一侧(通常;低;(侧)与管道相连,压力稳定位于不受室外风影响的空气中。现场的公共参考点(或通过集流管连接到压力稳定性)(解释:稳定性;位置没有变化。理想压力参考点的位置应具有体积大,开口少,与室外相比无压力变化或变化速度慢的特点。
  Large pharmaceutical companies that need to record large pressure differences usually use the common reference point method, which minimizes the number of pressure sensors and the combined error of multiple readings. One port of the pressure drop transmitter (usually; high; one side is connected to the monitored clean room, the other side (usually; low; one side) is connected to the pipeline, and the pressure is stable in the air that is not affected by the outdoor wind. A common reference point at the site (or connected to pressure stability through a manifold) (Interpretation: stability; no change in location. The position of ideal pressure reference point should have the characteristics of large volume, less opening, no pressure change or slow change compared with outdoor.
  二世。无尘车间静压差测定要求:
  II. Requirements for measurement of static pressure difference in dust free workshop:
  1. 当洁净车间的所有门都关闭时,确定静压差。
  1. When all doors of the clean workshop are closed, determine the static pressure difference.
  2. 从清洁度高的房间到清洁度低的房间再到直接通向室外的房间。
  2. From the room with high cleanliness to the room with low cleanliness to the room directly leading to the outside.
  3.试验管口设置在不受气流干扰的地方。
  3. The test nozzle shall be set at a place free from air flow interference.
  4. 测量数据应精确到1。0。
  4. The measurement data shall be accurate to 1. 0.

  三世。无尘车间静压差测量步骤:
  III. Measurement steps of static pressure difference in dust free workshop:
  1. 在清洁区域关闭所有的门。
  1. Close all doors in the clean area.
  2. 用差压计测量洁净室、洁净室与走廊之间、走廊与外界之间的压差。
  2. Use a differential pressure gauge to measure the pressure difference between the clean room, between the clean room and the corridor, and between the corridor and the outside.
  3.记录在案
  3. Record
  4. 静压差测定仪器:一般的静压差测定仪器有yjb-150补偿微压力计、倾斜压力计、精密指针压力计或灵敏度小于1的。其他0Pa压力计。
  4. Static pressure difference measuring instrument: general static pressure difference measuring instruments include yjb-150 compensation micro manometer, tilt manometer, precision pointer manometer or sensitivity less than 1. Other 0Pa pressure gauge.
