答：羅茨風機是空壓機嗎？關于這個問題，我個人認為羅茨風機不是空壓機，但在管道中增加儲氣罐后也可臨時用作空壓機使用！

　　空壓機：通常用作氣動機器或器具的動力源，一般氣壓較高，可達5kg/cm2--105kg/cm2，但風量較小;輸出空氣含有少量的油!

　　羅茨鼓風機：一般用作通風，輸氣;一般氣壓較低，風量較大。具有強制輸氣功能!輸出的空氣潔凈無油!

　　羅茨鼓風機與空壓機的區別如下：

　　1、一兩者都能產生壓力和流量，但用途卻不一樣;

　　2、羅茨鼓風機它的氣壓一般比較小(通常不會超過1kg/cm2)，但它的流量比較足，所以通常用在污水或水處理系統，有些生產線上也會用到中，主要用于攪拌吹氣或吸氣。

　　3、而空氣壓縮機它所產生的氣壓比較高(一般都在7kg/cm2左右)，主要用于驅動一些氣動設備等等。

　　4、羅茨鼓風機的壓力比較小而流量大。

　　5、空壓機的壓力可以大但流量小。 1Pa(帕斯卡): Pa=N/m^2 ，把G=9.8N/kg近似為10N/kg，那么1Kg相當于10N的壓力;又1MPa=1000000Pa;

　　所以P=1Kg/cm^2=10N/0.0001*m^2=10^5*N/m^2=0.1MPa

　　羅茨鼓風機是用來送風的，羅茨鼓風機利用三個葉形轉子在氣缸內作相對運動來壓縮和輸送氣體，也可用作真空泵。

　　空壓機是“空氣壓縮機”的簡稱，是產生壓縮空氣用的，可以產生高壓空氣。

　　羅茨風機風壓**一般是0.1MPa，而空壓機一般是0.6MPa。

　　空氣壓縮機分為兩大類，一類是容積型，一種是速度型。容積型又分為回復式和回轉式兩類;速度型則可分為軸流式、離心式和混流式三類。

　　羅茨鼓風機是屬于容積型空氣壓縮機中的回轉式類別，再往下分，就歸屬于轉子式了。

　　工作原理：羅茨風機為容積式風機，輸送的風量與轉數成比例，三葉型葉輪每轉動一次由 2 個葉輪進行 3 次吸、排氣。風機2根軸上的葉輪與橢圓形殼體內孔面，葉輪端面和風機前后端蓋之間及風機葉輪之間者始終保持微小的間隙，在同步齒輪的帶動下風從風機進風口沿殼體內壁輸送到排出的一側。

　　羅茨鼓風機內腔不需要潤滑油，結構簡單，運轉平穩，性能穩定。

　　用途：羅茨風機廣泛應用于化工、冶煉、污水處理、水產養殖、輕工、礦山、塑料、食品、電力、造紙等，采用機械密封可輸送煤氣、石油天然氣、氫氣、一氧化碳、乙炔等;選用不銹鋼葉輪可輸送含水氯化氫、硫化氫等腐蝕性有毒氣體。在氰化提金過程中浸出崗位所用的空壓機能不能用羅茨風機來代替，這個問題其實也是比較復雜的，需要考慮的是使用狀況(使用負荷，氣象條件等)，需要注意的是羅茨風機本身屬于高壓風機！

　　Answer: is roots blower an air compressor? On this issue, I personally think roots blower is not an air compressor, but it can also be used as an air compressor temporarily after adding an air storage tank in the pipeline!

　　Air compressor: usually used as the power source of pneumatic machines or appliances. Generally, the air pressure is high, up to 5kg/cm2--105kg/cm2, but the air volume is small; The output air contains a small amount of oil!

　　Roots blower: generally used for ventilation and gas transmission; Generally, the air pressure is low and the air volume is large. With forced gas transmission function! The output air is clean and oil-free!

　　Is roots blower an air compressor

　　The difference between Roots blower and air compressor is as follows:

　　1. Both of them can produce pressure and flow, but their uses are different;

　　2. Roots blower usually has a small air pressure (usually not more than 1kg/cm2), but its flow is relatively sufficient, so it is usually used in sewage or water treatment systems and in some production lines, mainly for mixing, blowing or inhaling.

　　3. The air compressor produces high air pressure (generally about 7kg/cm2), which is mainly used to drive some pneumatic equipment, etc.

　　4. Roots blower has small pressure and large flow.

　　5. The pressure of the air compressor can be large but the flow is small. 1pA (Pascal): pa=n/m^2, g=9.8n/kg is approximately 10n/kg, then 1kg is equivalent to 10N pressure; 1mpa=1000000pa;

　　So p=1kg/cm^2=10n/0.0001*m^2=10^5*n/m^2=0.1mpa

　　Roots blower is used to supply air. Roots blower uses three blade rotors to make relative movement in the cylinder to compress and deliver gas. It can also be used as a vacuum pump.

　　Air compressor is the abbreviation of "air compressor", which is used to produce compressed air and can produce high-pressure air.

　　The maximum air pressure of Roots blower is generally 0.1MPa, while that of air compressor is generally 0.6MPa.

　　Air compressors are divided into two categories, one is volume type, and the other is speed type. Volume type can be divided into two types: recovery type and rotary type; Speed type can be divided into axial flow type, centrifugal type and mixed flow type.

　　Roots blower belongs to the rotary type in the positive displacement air compressor. Further down, it belongs to the rotor type.

　　Working principle: Roots blower is a positive displacement blower, and the air volume conveyed is proportional to the number of revolutions. Each time the three blade impeller rotates, two impellers will conduct three times of suction and exhaust. There is always a small gap between the impeller on the two shafts of the fan and the hole surface in the elliptical shell, between the end face of the impeller and the front and rear end covers of the fan, and between the fan impellers. Driven by the synchronous gear, the wind is transmitted from the air inlet of the fan to the discharge side along the inner wall of the shell.

　　Roots blower has simple structure, stable operation and stable performance without lubricating oil.

　　Application: Roots blower is widely used in chemical industry, smelting, sewage treatment, aquaculture, light industry, mining, plastics, food, electric power, papermaking, etc. with mechanical seal, it can transport gas, oil and natural gas, hydrogen, carbon monoxide, acetylene, etc; Stainless steel impeller can be used to transport corrosive toxic gases such as aqueous hydrogen chloride and hydrogen sulfide. In the process of cyanidation gold extraction, whether the air compressor used in the leaching post can be replaced by roots blower is actually a complex problem. What needs to be considered is the service conditions (service load, meteorological conditions, etc.). What needs to be noted is that roots blower itself is a high-pressure blower!
