The negative pressure fan adopts the design of the physical principle of negative pressure ventilation and air convection, and uses the knowledge of fluid mechanics to scientifically and rigorously calculate and design the fan Angle, motor power, speed, wind pressure and air volume. When the fan is powered on, it can quickly reach a large amount of exhaust air, so that the indoor environment can quickly produce an air pressure difference between the outdoor and the indoor environment, forming a strong negative Налягане . Принудителният закрит мръсен зъл въздух трябва бързо да се изхвърля в съответствие с нашата посока на зададения поток, капки за налягане на въздуха, въздухът става тънък, образувайки отрицателна зона на налягане, за да се изхвърли на открито, за да се постигне едновременно с това, принудителен свеж въздух по отношение на компенсацията на разликата в налягането в стаята, така че да постигнеш работна снимка фабричен дим, изпускателна топлина, изпускане на изпускателния прах, вентилация и въздух
In practical applications, the negative pressure fan is often centrally installed on one side of the plant, and the air intake is located on the other side of the plant, and the air is formed by the air intake to the negative pressure fan. In this process, the doors and Windows near the negative pressure fan should be kept closed, the forced air is compensated by the doors and Windows on the air intake side into the factory building, flows through the factory building, and is discharged by the negative pressure fan, and the ventilation rate can be as high as 99. Through scientific and reasonable design, any high heat, harmful gases, dust and smoke can be quickly discharged from the workshop, and problems such as poor ventilation can be solved at one time.
