Clean room performance acceptance test

The clean workshop needs to carry out the wind speed, air volume and static pressure difference test, and then carry out the air cleanliness level test. On this basis, the installed filter leak detection, air flow visual inspection, self cleaning time, air tightness, temperature and humidity , illuminance and noise are tested; for one-way flow clean rooms, the air volume is determined by multiplying the average wind speed of the room section and the cross-sectional area. The measuring point is located about 150-300mm from the air outlet surface of the high-efficiency filter, and the section at the vertical airflow is used as the sampling. Section, the distance between measuring points on the section should not be greater than 0.6m, the number of measuring points should not be less than 4, and the arithmetic mean of all readings is taken as the average wind speed; When measuring the air volume of the tuyere by the tuyere air velocity method, the measuring points should not be less than 6 points on the plane of the tuyere outlet, and should be arranged evenly; Similarly, the length should not be less than twice the length of the side of the air outlet, the auxiliary air duct should completely cover the air outlet to be measured, and the measuring points on the outlet plane should not be less than 6, and should be arranged evenly.

The measurement of static pressure difference should be carried out after the air speed, air volume and air supply uniformity of the clean room have passed the inspection, and the inspection should be carried out when all doors are closed. Pa; when using an optical particle counter with a sampling flow greater than 1L/min, the particle size discrimination ability, the applicable range of particle concentration and the counting efficiency should be considered when selecting the instrument. The sampling points should be evenly distributed in the entire area of u200bu200bthe clean workshop or clean area, and located at the height of the working area. If there is no special regulation, the height of the working area should be 0.8m from the ground, and the minimum use time of each sampling point is 1min. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean workshops and clean rooms.

For the detection of differential pressure in clean operating rooms, directly read the data of instruments outside the operating room door or measure on-site with a liquid column micro differential pressure gauge at the beginning of the operation. Measure the hose so that the nozzle is at a height of 0.8m, and the end face of the nozzle is perpendicular to the ground, avoiding the airflow direction and the eddy current area, and then reading; the pressure difference between the clean area and the non-clean area, during the operation, the doors in all directions are closed. state; the dynamic plate method sampling should be carried out during the operation, and 3 Φ90 petri dishes are evenly placed in the middle of each air return port. The number of colonies is counted; other clean rooms are measured once at 10:00 am and 16:00 pm on the same day, and 3 Φ90 petri dishes are placed in the middle of each return air outlet, and placed at 35-37 ℃ immediately after sampling for half an hour Incubate for 24-48 hours, and then count the number of colonies formed by growth. When the dynamic planktonic bacteria impact method is used for detection, the sampler is placed 20cm away from the diagonal of the operating bed, with a height of 0.8-1.5m. When the room area is greater than 10m2, an additional sampling point is added for every 10m2.
