Explain about differential pressure control in purification engineering

The main points of differential pressure control in purification engineering are as follows:

1. The clean clean room modular and the surrounding space need to maintain the corresponding pressure difference, and the positive pressure difference and negative pressure difference should be determined according to the production process requirements.

2. The pressure difference between clean rooms of different grades and the clean area and the non-clean area should not be less than 5Pa, and the pressure difference between the clean area and the outdoor should not be less than 10Pa.

3. The differential pressure air volume required to maintain different differential pressure values u200bu200bin the clean room modular should be determined by the gap method or the number of air changes according to the characteristics of the purification project.

4. The opening and closing of the supply air, return air and exhaust air system should be interlocked. The positive pressure clean clean room modular interlock procedure is to start the supply fan first, and then start the return fan and exhaust fan; the interlock procedure should be reversed when it is closed. The negative pressure pharma clean room interlock procedure is the opposite of the positive pressure pharma clean room described above.

5. For non-continuously operating purification engineering workshops, on-duty air supply can be set according to the production process requirements, and purification and air conditioning treatment should be performed.
