SJG косой расхода вентилятора

The SJG oblique flow fan applies Ziwu Acceleration Theory, oblique flow impeller and drum awl tube cabinet. Makes the current on the Ziwu plane accelerate, reduces the static-pressure gradient, thus avoids and reduces the current detach, enhances the pressure coefficient and machine efficiency, reduces the noise. The pressure coefficient of the SJG oblique flow fan is higher than the axial one, the discharge coefficient is higher than the centrifugal one. This kind of unique aerodynamic characteristic, lets it suit in the ventilating duct pressurization and deliver or exhaust fan, however, the centrifugal and the axial is not suitable in this kind of situation. Under the same condition, using the SJG oblique flow fan to substitute the low pressure centrifugal fan and high pressure axial one may massively reduce the usage of noise elimination measure. The SJG oblique flow fan has 12 serial numbers, 27 kinds of specifications altogether. The volume covers 100m3/H 50000m3/H, the static pressure covers 20Pa 1100Pa, provides a broad choice for the users, may satisfy the different projects. Suitable situation: The rectilinear structure of the SJG oblique flow fan makes its inlet and outlet locate on the identical spool thread, the installment convenience. According to the air pipe situation, may be arranged in the middle of the pipe, or at the inlet and outlet. Especially at the narrow and small installment space, demonstrates its superiority of compact structure. The SJG oblique flow fan suits in pressurization, intake, exhausting and general taking a breath in each kind of civil and industry architecture. In the high or other building which needs to establish fire fighting smoke exhaust system, the positive pressure fan located in stair hall or first room will maintain an essential positive pressure, make sure the people escape safely.
