羅茨鼓風(fēng)機(jī)因其排氣壓力在允許范圍內(nèi)，調(diào)節(jié)時具有流量變動小、壓力選擇范圍寬和強(qiáng)制輸氣的特點(diǎn)，因而在冶金、化工及環(huán)保行業(yè)得到廣泛應(yīng)用。羅茨鼓風(fēng)機(jī)工作時最重要的便是葉輪，但由于長時間的使用，會出現(xiàn)一系列因受損或污染造成的操作故障或工作異常。

　　Roots blower is widely used in metallurgy, chemical and environmental protection industries due to its exhaust pressure being within the allowable range, small flow rate variation during adjustment, wide pressure selection range, and forced gas transmission characteristics. The most important component of a Roots blower during operation is the impeller, but due to prolonged use, a series of operational failures or abnormalities may occur due to damage or contamination.

　　接下來，我們聊一聊羅茨鼓風(fēng)機(jī)葉輪故障該采用的修復(fù)方法。

　　Next, let's talk about the repair methods that should be adopted for Roots blower impeller faults.

　　01如果羅茨鼓風(fēng)機(jī)葉輪的鉚釘頭部被磨損，可以通過壓緊葉輪體與輪轂用電焊堆焊，讓磨損的鉚釘頭部回到原來的正常狀態(tài)。

　　If the rivet head of the Roots blower impeller is worn, the worn rivet head can be restored to its original normal state by welding and welding the impeller body and hub tightly.

　　02如果鉚釘孔處容易產(chǎn)生疲勞裂紋，可用整根沒有用過的新焊條焊接修復(fù)裂紋，但要注意以葉輪軸心線為中心對稱進(jìn)行，將該裂紋處補(bǔ)焊剩下的焊條留在該處，再用一根新焊條修補(bǔ)相對稱的鉚釘孔裂紋，焊完后剩下的焊條與對稱鉚釘修補(bǔ)時剩下的焊條一樣長，以保證焊補(bǔ)上去的重量相等。

　　If fatigue cracks are prone to occur at the rivet hole, a new unused welding rod can be used to weld and repair the crack, but attention should be paid to symmetrical welding around the impeller axis. Leave the remaining welding rod at the crack repair location, and then use a new welding rod to repair the relatively symmetrical rivet hole crack. After welding, the remaining welding rod is the same length as the one left during symmetrical rivet repair to ensure that the weight of the welded repair is equal.

　　若是對稱的鉚釘孔處無裂紋也要將焊條堆焊于此處，用來抵消對稱鉚釘孔裂紋處新補(bǔ)的焊接重量。按照這種對稱補(bǔ)重的方法焊接，就可以修復(fù)裂紋。

　　If there are no cracks at the symmetrical rivet hole, the welding rod should also be welded here to offset the newly added welding weight at the symmetrical rivet hole crack. By welding using this symmetrical weight repair method, cracks can be repaired.

　　03對羅茨鼓風(fēng)機(jī)葉輪進(jìn)行簡單的動平衡試驗，方法也很簡單。把葉輪支起后用手撥動使之輕輕旋轉(zhuǎn)，達(dá)不到平衡的地方會停到最低點(diǎn)而且會左右擺動。

　　03 Conduct a simple dynamic balance test on the impeller of the Roots blower, and the method is also very simple. After supporting the impeller, gently rotate it by hand. If it cannot reach balance, it will stop at the lowest point and swing left and right.

　　若有偏重可在對面的葉輪上點(diǎn)焊，增加重量使其平衡，或者用角磨機(jī)磨去偏重葉輪的焊痕，也能達(dá)到平衡，這樣就可以把三葉羅茨鼓風(fēng)機(jī)修復(fù)好進(jìn)行正常工作了。

　　If there is a bias, spot welding can be done on the opposite impeller to increase its weight and balance it, or the welding marks on the bias impeller can be ground off with an angle grinder to achieve balance. This way, the three blade Roots blower can be repaired and operate normally.

　　在對羅茨鼓風(fēng)機(jī)的修理過程中，不能用電焊隨意點(diǎn)焊，將焊痕留到葉輪上，避免影響羅茨鼓風(fēng)機(jī)葉輪的平衡，這不但達(dá)不到修復(fù)的目的，反而造成更大的損失。

　　During the repair process of the Roots blower, welding should not be used randomly to spot weld, leaving welding marks on the impeller to avoid affecting the balance of the Roots blower impeller. This not only fails to achieve the purpose of repair, but also causes greater losses.
