low-pressure fan的意思|示意

WT35-11 comes as an axial-flow roof fan that features low and medium levels of pressure and heavy wind flow and can be geared to the needs of blowing, exhaust and double-rotation reversible mode.

WT35-11型为屋顶轴流式通风机，该风机为中低压大流量风机，可设计成送风、排风或双旋转可逆式。

Compressor of high and low pressure, exhaust temperature, air volume loss, and fan overload multiple protective measures .

压缩机高低压，排气高温，风量丢失，风机过载等多重保护措施。

The way that counter rotating local fan with the characteristics of high efficency, low noise, high pressure and large flow rate is not practical is put forward.

提出 对旋式局部通风机具有高效率、低噪声、高风压、大风量性能特性的说法是不符合实际的宣传。

The recuperators have high air resistance , low air preheating temperature and high fan pressure head , and fan has much noise to environment and are apt to break down with vibration .

此换热器空气阻力大，空气预热温度不高，风机压头高，环境噪声大，风机振动大、易损坏。

The stall surging characteristic and its prevention measure are analysed with focus on low-pressure axial fan, high-pressure axial fan and mutiple-stage axial compressor.
