這是為了保護風機。其實不光是羅茨風機,包括一些離心風機,旋渦風機,高壓風機,都是需要保護的。只是保護的方式不一樣而已,常見的是變頻器,負載電磁保護閥。
This is to protect the fan. In fact, not only roots fans, but also some centrifugal fans, vortex fans and high-pressure fans need to be protected. It's just that the way of protection is different. The common ones are frequency converter and load electromagnetic protection valve.
一般控制電機的電流和內(nèi)壓即可保護風機了。 當然不排除很多沒有使用保護方式也能長期運行的機器,但是機器本身的壽命肯定是受影響的。 就像摩托車一樣,有的然不知道換機油這回事,一樣的騎了幾萬。
Generally, the fan can be protected by controlling the current and internal pressure of the motor. Of course, many machines that can operate for a long time without protection are not excluded, but the service life of the machine itself must be affected. Like motorcycles, some of them didn't know how to change the oil and rode for tens of thousands of kilometers.
但是廠方的建議肯定是經(jīng)常換機油的。這就是同樣一個道理了.
But the manufacturer's suggestion must be to change the oil often. This is the same truth
雙級羅茨風機是由兩臺HSR系列標準羅茨鼓風機串聯(lián)而成。當氣體進入風機升壓后,經(jīng)過中間冷卻器將氣體溫度降40℃以下,然后進入二級風機繼續(xù)升壓,機組升壓可達177kPa。兩級風機的主機由同一臺電機通過皮帶傳動或雙軸伸電機直聯(lián)傳動。
The two-stage roots blower is composed of two HSR series standard roots blowers in series. After the gas enters the fan for boosting, the temperature of the gas is reduced to below 40 ℃ through the intercooler, and then enters the secondary fan to continue boosting, and the pressure of the unit can reach 177kpa. The main machine of the two-stage fan is directly driven by the same motor through belt drive or double shaft extension motor.
應(yīng)用范圍及輸送介質(zhì)雙級羅茨風機是一種由兩臺羅茨風機串聯(lián)組成的裝置。每臺風機箱體內(nèi)部均有兩個轉(zhuǎn)向相反的三葉型轉(zhuǎn)子,每個三葉型轉(zhuǎn)子用兩個軸承支撐,利用一對高精度的同步直齒輪,使兩個轉(zhuǎn)子的相對位置始終保持不變,轉(zhuǎn)子之間以及轉(zhuǎn)子與箱體之間保持***的間隙,無接觸旋轉(zhuǎn)。轉(zhuǎn)子在側(cè)箱體同步齒輪的驅(qū)動下,借助兩轉(zhuǎn)子的“嚙合”,使進氣口與出氣口相互隔開,完成箱體和轉(zhuǎn)子間的密閉氣體從吸入側(cè)到吐出側(cè)的移送過程。在旋轉(zhuǎn)過程中無內(nèi)壓縮地將工作腔內(nèi)的氣體從進氣口推移到出氣口。轉(zhuǎn)子與轉(zhuǎn)子、轉(zhuǎn)子與箱體、轉(zhuǎn)子與墻板之間都有微小間隙,因而工作腔內(nèi)沒有摩擦,無接觸磨損部分。
Application scope and conveying medium double-stage roots blower is a device composed of two roots blowers in series. There are two three blade rotors with opposite steering in the inner part of each typhoon case. Each three blade rotor is supported by two bearings. A pair of high-precision synchronous spur gears are used to keep the relative position of the two rotors unchanged, and * * * clearance is maintained between the rotors and between the rotor and the case without contact rotation. Driven by the synchronous gear of the side box, the rotor separates the air inlet from the air outlet with the help of the "meshing" of the two rotors, so as to complete the transfer process of the closed gas between the box and the rotor from the suction side to the discharge side. In the process of rotation, the gas in the working chamber is pushed from the inlet to the outlet without internal compression. There is a small gap between the rotor and the rotor, between the rotor and the box, and between the rotor and the wall panel, so there is no friction and contact wear in the working cavity.
性能特點:
Performance characteristics:
1、雙級三葉羅茨風機容積效率高,供氣量大,運行平穩(wěn),使用可靠,具有比較穩(wěn)定的工作特性。
1. The two-stage three blade roots blower has high volumetric efficiency, large air supply, stable operation, reliable use and relatively stable working characteristics.
2、葉輪和軸為整體結(jié)構(gòu)且葉輪無磨損,風機性能長時間不變,可以長期連續(xù)運轉(zhuǎn)。
2. The impeller and shaft are of integral structure, and the impeller is free of wear. The performance of the fan remains unchanged for a long time and can operate continuously for a long time.
3、強制輸氣,流量隨壓力變化小,出口壓力由背壓決定,且輸送氣體不受油污染。
