怎么判斷羅茨風(fēng)機(jī)齒輪磨損程度?

一般羅茨風(fēng)機(jī)都是不允許反轉(zhuǎn)的(因?yàn)檫M(jìn)氣口跟排氣口的間隙設(shè)置不一樣),所以羅茨風(fēng)機(jī)都需要在排氣端設(shè)置單向閥。也就是允許風(fēng)從羅茨風(fēng)機(jī)輸入到管道系統(tǒng),防止羅茨鼓風(fēng)機(jī)突然停機(jī),羅茨風(fēng)機(jī)而系統(tǒng)的氣體收到系統(tǒng)壓力的作用,回流沖擊羅茨風(fēng)機(jī)造成羅茨風(fēng)機(jī)反轉(zhuǎn),損壞羅茨鼓風(fēng)機(jī)另外,幾臺(tái)羅茨鼓風(fēng)機(jī)并聯(lián)運(yùn)行的時(shí)候,假設(shè)其中一臺(tái)不工作,那么單向閥也可以防止排氣端的氣體通過(guò)這臺(tái)沒(méi)有使用的羅茨鼓風(fēng)機(jī),造成其反轉(zhuǎn)損壞。
Generally, the roots blower is not allowed to reverse (because the gap setting between the air inlet and the exhaust port is different), so the roots blower needs to set a check valve at the exhaust end. In other words, it allows the air to be input from roots blower to the pipeline system to prevent the roots blower from sudden shutdown. The roots blower and the gas in the system receives the effect of system pressure, and the backflow impacts the roots blower, causing the roots blower to reverse and damage the roots blower. In addition, when several roots blowers operate in parallel, it is assumed that one of them does not work, Then, the check valve can also prevent the gas at the exhaust end from passing through the unused roots blower, resulting in reverse damage.
總而言之,就是保護(hù)羅茨風(fēng)機(jī)不反轉(zhuǎn).按結(jié)構(gòu)形式分:立式型羅茨風(fēng)機(jī)兩轉(zhuǎn)子中心線在同一垂直水平面內(nèi),氣流水平進(jìn),水平出;臥式型羅茨風(fēng)機(jī)兩轉(zhuǎn)子中心線在同一水平面內(nèi),氣流垂直進(jìn),垂直出。所說(shuō)的風(fēng)葉相碰。
In short, it is to protect the roots blower from reverse rotation. According to the structural form, the center lines of the two rotors of the vertical roots blower are in the same vertical horizontal plane, and the air flow enters and exits horizontally; The center lines of two rotors of horizontal roots blower are in the same horizontal plane, and the air flow enters and exits vertically. The wind leaves collide.
絕大部分是軸承間隙變大引起的,如果更換同步齒輪不行,建議使用質(zhì)量較好的軸承,不用進(jìn)口的起碼也得用瓦軸或洛軸的高速軸承,羅茨風(fēng)機(jī)齒輪的磨損可以根據(jù)齒輪咬合間隙判斷,如果齒輪磨損超限,可以將兩個(gè)同步齒輪翻面處理,這樣齒輪就可以延長(zhǎng)一倍使用壽命,調(diào)整兩風(fēng)葉間隙時(shí)一定要用塞尺沿風(fēng)葉長(zhǎng)度測(cè)定4個(gè)點(diǎn)以上,羅茨鼓風(fēng)機(jī)保證整個(gè)長(zhǎng)度上的間隙均勻、一致。
Most of them are caused by the larger bearing clearance. If it is not possible to replace the synchronous gear, it is recommended to use bearings with better quality. If it is not necessary to import, at least the high-speed bearings of bearing bush or Luo shaft should be used. The wear of Roots blower gear can be judged according to the gear engagement clearance. If the gear wear exceeds the limit, the two synchronous gears can be turned over, In this way, the service life of the gear can be doubled. When adjusting the clearance between the two blades, be sure to use a feeler gauge to measure more than 4 points along the length of the blades. Roots blower ensures that the clearance on the whole length is uniform and consistent.
