Clean workshop has higher requirements for temperature, humidity, air pressure and other aspects, among which air pressure control is a very important point, which is also an effective way to ensure the cleanliness of the workshop. So, how to control the pressure difference in clean area?
Concept of differential pressure
The air of nature will flow. This flow is caused by pressure difference. The pressure difference between indoor and outdoor atmosphere in clean area is called differential pressure. The air will flow to the place with high absolute pressure difference to the place with low pressure difference, so the cleanliness of the room is directly proportional to the absolute pressure difference. When the door of the clean area is opened, the air will flow from the place with high cleanliness to the place with low cleanliness, which ensures that the environment with high cleanliness will not be polluted by the air in the low-level room. This is the working principle of the differential pressure in the clean area.
How to control the pressure difference in clean area
In the construction of clean area, to control the differential pressure, it is necessary to develop a practical scheme, such as the following steps:
1. Determine the pressure difference in the clean room
2. Calculate the pressure difference air volume of the clean room to maintain the differential pressure
3. Some technical measures are used to ensure the pressure difference and air volume of the clean room and keep the pressure difference constant.
Construction of clean workshop, find professional clean engineering to do, so that we can build a high-quality clean space. Professional companies in this area have experience and strength, is able to let everyone rest assured. When looking for the cleaning company, you can ask the other party to show the workshop design plan. If there is any problem, communicate with the company and put forward it in time if it needs to be rectified. In this way, you don't have to worry that the clean area constructed will not meet the actual use needs.
How to control the pressure difference in clean area? Now you know, in short, the clean area should pay attention to technology, not be able to do it casually. Professional purification engineering company can ensure to create a perfect clean workshop.
