HIGH PRESSURE FAN的意思|示意

Air pressure protection device: When the fan doesn't work, or the flue pipe is blocked, or the air pressure is too high, combustion will automatically stop.

风压过大保护装置：当风机故障、烟道堵赛、风压过大时，燃烧自动停止。

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。

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 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.

针对低、高压轴流送风机及多级轴流压缩机在低流量区域的失速喘振特性及其预防措施进行了分析。

The measurements show that the airfoil blade fan prevails over the plate one in the aspects of total pressure efficiency, stable operation range and high efficient operation range.

试验结果表明机翼型叶片在全压效率、稳定运行范围及高效运行范围比相应的板型叶片具有优越性；

Using this design system, a high-loaded backward-swept fan with a stage pressure ratio of 2.2 was redesigned firstly as a backward-swept and secondly as a forward-swept splittered fan.

用该系统对某级增压比2.2的单级高负荷后掠风扇进行了后掠和前掠大小叶片改型设计。
