Keywords： dry(oilfree)vacuum。為了適應我國開發(fā)研究生產(chǎn)螺桿真空泵的需要，本文對雙螺桿真空泵的設計型線組成問題等內(nèi)容進行了的研究與探討。雖然我國對無油真空泵的需求日益增長，但是許多跨國公司的真空泵產(chǎn)品卻在我國的高端真空泵市場中占據(jù)了主導位置。 題目： LWZ150 雙頭螺桿型干式無油真空泵的設計 2020 年 05 月 I LWG150 雙頭螺桿型干式無油真空泵的設計 摘 要 干式雙螺桿真空泵是一種容積式無油真空泵，具有結(jié)構(gòu)緊湊，抽速大，真空度高，可直排大氣，使用壽命長，自吸能力強，無易損件，運轉(zhuǎn)可靠，維修維護方便，動平衡性好，振動小，無壓力脈動與噪音，可高速平穩(wěn)的一作，適應性強，還可用于多相混輸，無喘振現(xiàn)象，易于實現(xiàn)連續(xù)排氣等諸多優(yōu)點，因此廠泛的應用于冶金、電子、化學、食品、醫(yī)藥、環(huán)保等工業(yè)生產(chǎn)部門。國外已發(fā)展出諸多此類 真空泵產(chǎn)品，而在我國的發(fā)展卻相對落后。因此，自行研究經(jīng)濟可行、運轉(zhuǎn)可靠的無油真空泵意義可見一斑。 關鍵詞 ：雙頭干式真空泵 ； 螺桿 ； 型線 II LWZ150 DoubleHeaded Screw Type Dry Vacuum Pump Abstract The oilfree twinscrew vacuum pump is a new kind of rotational positive displacement structure of the pump is simple and liquids or solids are hard to accumulate when sucked with gas or are condensed or solidified in the pump. It is outstanding for its excellent efficiency, high vacuum, exhausting to the air directly, a long life, good sucking, reliable work, convenient maintenance, favorable dynamical balance, light vibration, no pressure fluctuate and noise, work placidly with high speed, strong adaptability, muftiphase duties, no quiver, easy to continuous exhausting, etc. It is used widely in industrial territory of metallurgy, electron, chemistry, pharmacy, food and environment, and so on. At present, all over the world have been trying their best to develop oilfree vacuum pumps, but our country has been fallen behind other countries. Although the demand of the oilfree vacuum pumps has been experiencing a rapid growth, the products of many multinational panies take up the major market share of dry pression vacuum pumps and high vacuum pumps. Therefore it is very significant to develop economical, feasible and reliable dryrunning vacuum pumps by us. For the sake of requirements of developing and researching in our country, the paper investigates the meshing theory of twinscrew pump, buildup of the rotors39。pump。 多頭雙邊對稱圓弧型線方程 .............................................................. 11 3 螺桿雙頭干式真空 泵工作原理 .................................... 錯誤 !未定義書簽。 壓縮過程 .......................................................................... 錯誤 !未定義書簽。 4 螺桿雙頭干式真空泵設計計算 .................................... 錯誤 !未定義書簽。 排氣量 .............................................................................. 錯誤 !未定義書簽。 實際排氣量 ............................................................ 錯誤 !未定義書簽。 軸向進氣口 ............................................................ 錯誤 !未定義書簽。 極限真空度、功率及冷卻水量 ...................................... 錯誤 !未定義書簽。 同步齒輪的設計計算 .................................................
