羅茨風機型號及選型參數表

　　羅茨風機是容積式風機的一種，有兩個三葉葉輪在由機殼和墻板密封的空間中相對轉動，由于每個葉輪都是采用漸開線，或是外擺線的包絡線，每個葉輪的三個葉片是完全相同的，同時兩個葉輪也是完全相同的，這樣就大大降低了加工難度。葉輪在加工時采用數控設備，確保了兩個葉輪在中心距不變情況下，不管兩個葉輪旋轉到什么位置，都能保持一定的極小間隙，從而確保氣體的泄露在允許范圍內。兩個葉輪相向轉動，由于葉輪與葉輪、葉輪與機殼、葉輪與墻板之間的間隙極小，從而使進氣口形成了真空狀態，空氣在大氣壓的作用下進入進氣腔，然后，每個葉輪的其中兩個葉片與墻板、機殼構成了一個密封腔，進氣腔的空氣在葉輪轉動的過程中，被兩個葉片所形成密封腔不斷地帶到排氣腔，又因為排氣腔內的葉輪是相互嚙合的，從而把兩個葉片之間的空氣擠壓出來，這樣連續不停的運轉，空氣就源源不斷地從進氣口輸送到出氣口，這就是羅茨風機的整個工作過程。

　　羅茨鼓風機與其它類型的鼓風機相比較，有如下優點，

　　1) 在很寬的壓力范圍內(10?10-2Torr)，具有穩定的大抽速，能迅速排出突然放出的氣體，彌補了油封機械泵和擴散泵的不足，很適宜作機械增壓泵之用。在有水封或油封的情況下，能直排大氣抽真空，也適宜作大抽速的粗鼓風機。

　　2)設計先進，結構合理，轉子間及轉子與泵體間均有間隙，互不接觸，不用潤滑，摩擦損失小，可用較低的動力獲得較大的抽速，有顯著的節能效果。

　　3)轉子有良好的幾何對稱性，工作平穩，能用提高轉速的辦法獲得大抽速，從而做到結構緊湊、體積小、重量輕。

　　4)泵腔內不發生氣體壓縮，加之運動件之間有間隙，對抽吸氣體中的灰塵和水蒸汽不敏感，因此可抽出可凝性蒸汽。

　　5)泵腔內運動件無需用油潤滑，能避免油蒸汽對真空系統的污染，有利于獲得無油真空。

　　6)無需進排氣閥，結構簡單，噪聲較低，泵腔內運動件互不接觸，不易損壞，維護費用低。

　　7)啟動快，能在短時間內達到極限真空。

　　Model and model selection parameter table of Roots blower

　　Roots blower is a kind of positive displacement blower. There are two three blade impellers that rotate relatively in the space sealed by the casing and wall panel. Since each impeller adopts the envelope of involute or cycloid, the three blades of each impeller are identical, and the two impellers are identical, which greatly reduces the processing difficulty. The impeller is processed with numerical control equipment, which ensures that no matter where the two impellers rotate, they can maintain a certain minimum gap under the condition of constant center distance, so as to ensure that the gas leakage is within the allowable range. The two impellers rotate towards each other. Because the clearance between the impeller and the impeller, between the impeller and the casing, and between the impeller and the wallboard is very small, a vacuum state is formed at the air inlet. The air enters the air inlet chamber under the action of atmospheric pressure. Then, two blades of each impeller, the wallboard and the casing form a sealing chamber. The air in the air inlet chamber is continuously brought to the exhaust chamber by the sealing chamber formed by the two blades during the rotation of the impeller, Because the impellers in the exhaust chamber mesh with each other, the air between the two blades is squeezed out. In this way, the air is continuously transmitted from the air inlet to the air outlet. This is the whole working process of Roots blower.

　　Model and model selection parameter table of Roots blower

　　Compared with other types of blowers, roots blower has the following advantages,

　　1) In a wide pressure range (10? 10-2torr), it has a stable large pumping speed, and can quickly discharge the suddenly released gas, making up for the shortcomings of oil sealed mechanical pump and diffusion pump. It is very suitable for mechanical booster pump. In case of water seal or oil seal, it can directly exhaust the atmosphere for vacuum pumping, and is also suitable for coarse blower with large pumping speed.

　　2) Advanced design, reasonable structure, clearance between rotors and between rotors and pump body, no contact with each other, no lubrication, small friction loss, large pumping speed can be obtained with low power, with significant energy-saving effect.

　　3) The rotor has good geometric symmetry, works stably, and can obtain large pumping speed by increasing the rotating speed, so as to achieve compact structure, small volume and light weight.

　　4) There is no gas compression in the pump chamber. In addition, there is a gap between the moving parts, which is insensitive to the dust and steam in the pumped gas. Therefore, condensable steam can be pumped out.

　　5) The moving parts in the pump chamber do not need oil lubrication, which can avoid the pollution of oil steam to the vacuum system, and is conducive to obtaining oil-free vacuum.

　　6) The utility model has the advantages of simple structure, low noise, no contact between moving parts in the pump chamber, no damage and low maintenance cost.

　　7) Fast start, can reach the limit vacuum in a short time.

　　Roots Blower

　　Roots blower is a double impeller synchronous compression machine. Each three blade rotor is supported by two bearings and a pair of synchronous gears are used to keep the relative positions of the two rotors unchanged. It is a positive displacement blower with forced gas transmission characteristics. As a rotary machine, the three blade roots blower has relatively stable working characteristics. There is a small gap between the rotor and the rotor, between the rotor and the pump body, and between the rotor and the side cover of the three blade roots blower, so there is no friction and contact wear in the working chamber; Roots blower is economical and durable, without lubrication, with long service life and good power balance. There are six suction and exhaust processes in a week, with high volumetric efficiency. The utility model has the advantages of simple structure, convenient use and maintenance, no need of internal lubrication, and the transmitted medium is oil-free. The support of the pump rotor adopts a reliable clearance elimination structure, the rotating parts are carefully dynamically balanced, and high-precision helical gears are used. Therefore, the pump operates stably, has low noise, is more reliable, and can operate under high pressure difference for a long time.
