滑閥式真空泵:
Slide valve vacuum pump:
主要廣泛應用于拉晶、鍍膜、冶金、熱處理、浸漬、干燥、蒸餾、練泥、航空航天模擬試驗等新材料、新技術(shù)、新工藝必須在真空條條下的生產(chǎn)與研制中。
Mainly widely used in the production and development of new materials, technologies, and processes such as crystallization, coating, metallurgy, heat treatment, impregnation, drying, distillation, mud refining, aerospace simulation experiments, etc. must be carried out under vacuum conditions.
滑閥真空泵即可單獨進(jìn)行使用，也可作為羅茨真空泵、油增壓泵、油擴散泵的前級泵來(lái)搭配使用，但當抽吸有腐蝕性的黑色金屬且對真空油起化學(xué)反應、并含有大量蒸汽和大量粉塵的氣體時(shí)，必段要安裝其它需附加的裝置。
The slide valve vacuum pump can be used alone, or as the front pump of Roots vacuum pump, oil Booster pump, and oil diffusion pump. However, when pumping corrosive Ferrous, causing chemical reaction to the vacuum oil, and containing a large amount of steam and dust, other additional devices must be installed.
優(yōu)點(diǎn)：相比旋片式真空泵，它的耐用性要比前者更高好幾倍且抽氣速率大，但相對也會(huì )更高一點(diǎn)；
Advantages: Compared to rotary vane vacuum pumps, their durability is several times higher and their pumping rate is large, but their prices are relatively higher;
如果是用來(lái)作為抽除密閉容器的氣體的基本設備之一，那它可以單獨使用，同時(shí)也可作為增壓泵、擴散泵、分子泵的前級泵來(lái)配套使用，該型泵廣泛應用于冶金、機械、電子、化工、石油、醫藥等行業(yè)的真空冶煉、真空鍍膜、真空熱處理，真空干燥等工藝過(guò)程中。

If it is used as one of the basic equipment for removing the gas from the closed container, it can be used alone, and can also be used as the front pump of Booster pump, diffusion pump, and molecular pump. This type of pump is widely used in vacuum smelting, vacuum coating, vacuum heat treatment, vacuum drying and other processes in metallurgy, machinery, electronics, chemical industry, petroleum, medicine and other industries.
旋片式真空泵:
Rotary vane vacuum pump:
該泵估具有結構緊湊，體積小，重量輕，噪音低，振動(dòng)小等優(yōu)點(diǎn)。所以它比較適合用來(lái)作為擴散泵的前級泵，而且更適合在精密儀器配套的實(shí)驗室中來(lái)使用。例如：質(zhì)譜儀器，冰箱流水線(xiàn)，真空冷凍干燥機等。
The pump has the advantages of compact structure, small volume, light weight, low noise, and low vibration. So it is more suitable as a front stage pump for diffusion pumps, and is more suitable for use in laboratories equipped with precision instruments. For example: mass spectrometry instruments, refrigerator assembly lines, vacuum freeze-drying machines, etc.
羅茨真空泵:
Roots vacuum pump:
這是一款旋轉式的變容真空泵，必須跟前級泵配合后才能使用，它在較寬的壓力范圍內時(shí)，會(huì )具有較大的抽速，而且在對被抽除含有灰塵和水蒸汽氣體也不地太敏感。
This is a rotary variable capacity vacuum pump that must be used in conjunction with the front stage pump. It has a large pumping speed over a wide pressure range and is not very sensitive to the removal of gases containing dust and water vapor.
廣泛用于冶金、化工、食品、電子鍍膜等行業(yè)。適合跟真空機組主泵來(lái)搭配的前級泵輔泵有如下幾種：水環(huán)式真空泵，滑閥真空泵，立式無(wú)油真空泵，分子真空泵等等。
Widely used in industries such as metallurgy, chemical industry, food, electronic coating, etc. There are several types of front stage pump auxiliary pumps suitable for matching with the main pump of the vacuum unit: water ring vacuum pump, slide valve vacuum pump, vertical oil-free vacuum pump, molecular vacuum pump, and so on.
