抽气机

或不用抽气机，而在进气管道有一接高压清洁空气的进气口（4）。

Otherwise , the air exhauster is not necessary , and the air inlet ( 4 ) connecting with the high-pressure clean air is arranged in the air inlet pipeline .

该管道有一清洁空气进口（4），还设有抽气机与排尘管的排气口（6）相连接。

The pipeline is provided with a clean air inlet ( 4 ), and an air exhauster is provided to connect with the air outlet ( 6 ) of the dust removing pipe .

抽气机抽气与引射器引气建立发动机喷口环境条件的经济分析

An Economical Analysis between Pumping with Exhaust Blower and Injecting with Injector to Establish Engine Nozzle Conditions

在冬天，屋顶处的抽气机可被关闭，使大量暖空气在室内循环。

In winter , the roof ventilator is closed and the majority of the warmed air is reused ;

这种高速的空气在火车上创造了一个抽气机，就像一辆高速行驶的汽车开着车窗能够吸出地图和纸张。

This speeding air creates a suction on the train , just like opening the window of a speeding car can suck out maps and paper .

但是，电虽不供给我可以呼吸的空气，它可以发动强大的抽气机，把空气送人特殊的密封室。

However , even though electricity doesn 't supply me with breathable air , it at least operates the powerful pumps that store it under pressure in special tanks .

在给定的航空发动机排气条件下，对高空台排气系统中抽气机抽气和引射器引气这两种设计方案的投资和运行能耗进行了对比和简要的分析。

Comparison and preliminary analysis are made between two design schemes of pumping with exhaust blower and injecting with injector for the investment and energy consumption in operation at given engine exhaust conditions .
