注意事項(xiàng):
FZ型避雷器。這種避雷器在火花間隙旁并聯(lián)有分路電阻,保護(hù)性能好。主要用于3~220kV電氣設(shè)備的保護(hù)。這是一種磁吹式閥型避雷器,火花間隙不但有分路電阻,還有分路電容,保護(hù)性能較為,主要用于電機(jī)的保護(hù)。也是一種磁吹式閥型避雷器,電氣性能更好,專用于變電所高壓電氣設(shè)備的保護(hù)。 3 泵的串、并連調(diào)節(jié) 性:必須選用相應(yīng)防爆等級(jí)產(chǎn)品,露天安裝或粉塵多應(yīng)選用防水,防塵品種。 先沿著垂直方向切割管道,并修整、去除毛刺,測(cè)量管徑。Cut tube end square. Ream, burr and size. 使用紗布或鋼絲刷管道和切割部位,使其金屬表面發(fā)光發(fā)亮。 Use sand cloth or steel wire brush to clean both ends to a bright metal finish. Steel wool is not recommended. 在管道的外面和焊接罩的內(nèi)部涂上焊劑,焊劑必須完全覆蓋焊接表面。 Apply flux to outside of tube and inside of solder cup. Surfaces to be joined must be completely covered. Use flux sparingly. 要確保閥門處于開(kāi)啟狀態(tài)。 Be sure that valve is fully open. Apply heat to tube first. Transfer as much heat as possible through tube into valve. Avoid prolonged heating of valve itself. 銀釬焊的:對(duì)需要進(jìn)行釬焊的部件進(jìn)行組裝。如果允許涂上焊劑的部件處于直立狀態(tài),那么焊劑中的水分會(huì)蒸發(fā)掉,而干燥的焊劑很容易脫落,致使的金屬表面容易被氧化。在進(jìn)行連接組裝時(shí),要將管道管套直到遇到阻擋為止。組裝是要保證有穩(wěn)固的支撐,使得整個(gè)釬焊操作中能夠保持在直線位置。 Silver Brazing Method: Assemble parts to be brazed. If fluxed parts are allowed to stand, the water in the flux will evaporate, and dried flux is liable to flake off, exposing metal surfaces to oxidation. Assemble joint by inserting tube into socket hard against the stop. The assembly should be firmly supported so that it will remain in alignment during the brazing operation. 注:對(duì)于1英寸或更大公稱通徑的閥門,一次性將連接部件加熱到所需溫度比較困難。為了在整個(gè)大面積上保持正常的溫度,通常情況下需要兩個(gè)焊。建議對(duì)整個(gè)管套區(qū)域進(jìn)行適當(dāng)?shù)念A(yù)熱。建議采用火焰對(duì)連接部件進(jìn)行加熱。首先從離閥門1英寸的地方開(kāi)始對(duì)管道進(jìn)行加熱,然后圍繞著管道短距離上下交替對(duì)管道進(jìn)行火焰烘烤,并以適當(dāng)?shù)慕嵌裙艿溃苊鉄┕艿。火焰要連續(xù)運(yùn)動(dòng),不允許停留在某一點(diǎn)上。 NOTE: On one-inch and larger valves, it is difficult to bring the whole joint up to temperature at one time. It will frequently be found desirable to use a double-tip torch to maintain the proper temperature over the larger area. A mild pre-heating of the whole socket area is recommended. Apply heat to parts to be joined. The preferred method is by oxy-acetylene flame. Heat tube first, beginning one inch from edge of valve. Sweep flame around tube in short strokes up and down at right angles to run of tube. To oid burning through tube, the flame should be in continuous motion and not allowed to remain on any one point. 在閥門的套筒底座用火焰進(jìn)行烘烤。加熱要均勻,用火焰對(duì)閥門及管道進(jìn)行火焰烘烤的要延續(xù)到閥門上的焊劑不再發(fā)出聲音。 Apply flame to valve at base of socket. Heat uniformly, sweeping flame from valve to tube until flux on valve becomes quiet. Avoid excessive heating of valve. 當(dāng)焊劑變成液態(tài)并且在管道和閥門上呈現(xiàn)半狀態(tài)時(shí),開(kāi)始將火焰沿著連接部件的軸線進(jìn)行進(jìn)退烘烤,以保持連接部件、特別是閥門套筒底座部位的熱度。 When flux appears liquid and transparent on both tube and valve, start sweeping flame back and forth along axis of joint to maintain heat on parts to be joined, especially toward base of valve socket. 使用適量的焊料:如果使用線狀焊料,那么對(duì)公稱通徑為3/4英寸的閥門就要采用3/4英寸的焊料,等等。如果使用的焊料太多,那么有些焊料可能會(huì)流過(guò)管道阻擋部位,并堵塞密封區(qū)域。在安裝連接部件時(shí),可以看到焊料和釬焊合金繼續(xù)流動(dòng) Use just enough solder: with wire solder, use 3/4" for a 3/4" valve, etc. If too much solder is used, it may flow past tube stop and clog sealing area. When joint is filled, a continuous run of solder or brazing alloy will be visible. 銀釬焊法:將焊線或焊桿點(diǎn)在閥門里的管道套座上。當(dāng)焊桿或焊線進(jìn)入連接處時(shí)要將火焰從其上面移開(kāi)。當(dāng)合金流進(jìn)連接處時(shí),要前后火焰。達(dá)到適當(dāng)?shù)臏囟群,合金將迅速容易地流進(jìn)管道外殼和閥門套管之間的空間。連接處被充滿后,就會(huì)看到焊接合金的邊緣。 Silver Brazing Method: Apply brazing wire or rod at point where tube enters valve socket. Keep flame away from rod or wire as it is fed into the joint. Move flame back and forth as alloy is drawn into joint. When the proper temperature is reached alloy will flow readily into space between tube outer wall and valve socket. When joint is filled, a continuous rim of brazing alloy will be visible. 當(dāng)焊料處于粘滯狀態(tài)時(shí),用刷子把多余的焊料干凈。焊料冷卻后,將一條嵌條環(huán)繞在閥門的端口。 Remove excess solder with small brush while plastic, leing a fillet around end of valve as it cools. 銀釬焊就更早了,早可以追溯到1932年,當(dāng)時(shí)的湖南汽車修理總廠在湘潭下攝司、湘鄉(xiāng)等地設(shè)立分廠,在進(jìn)行汽車大修業(yè)務(wù)的同時(shí),監(jiān)造、環(huán)、飛輪殼和水泵總成等10多種配件新成立后,江南機(jī)械廠根據(jù)市場(chǎng)需要,先后生產(chǎn)出7種汽車零部件到了1985年,湘潭從事汽車配件制造的工廠已有5家雖然湘潭汽車及零部件產(chǎn)業(yè)起步較早,卻發(fā)展,甚至是“動(dòng)動(dòng)停!边@其中的原因有很多,也許是自主品牌定位,也許錯(cuò)過(guò)了幾次關(guān)鍵的技術(shù)轉(zhuǎn)型契機(jī),也許是歷史的深層次原因,也許是發(fā)展體制的問(wèn)題,直到本世紀(jì)初,湘。
