SMH120R54E6.7W30三螺桿泵。稀油站SMH系列點(diǎn)火油泵
三螺桿泵的安裝位置距油面太高,特別是在泵轉(zhuǎn)速降低時(shí),因不能保證泵吸油腔有必要的真空度造成吸油不足而吸入空氣。此時(shí)應(yīng)調(diào)整泵與油面的相對(duì)高度,使其知足劃定的要求。
The installation position of the three screw pump from the oil surface is too high, especially in the pump speed is reduced, because the vacuum pump suction chamber can not guarantee the necessary degree of suction caused by insufficient inhalation of air. You should adjust the oil pump and the relative height, make it satisfy formularyrequirement.
吸油濾油器被污物堵塞或其容量過(guò)小,導(dǎo)致吸油阻力增加而吸入空氣;另外,進(jìn)、出油口的口徑較大也有可能帶入空氣。此時(shí),可清洗濾油器,或選取較大容量、且進(jìn)出口徑適當(dāng)?shù)臑V油器。三螺桿泵不但能防止吸入空氣,還能防止產(chǎn)生噪聲。
Oil filter is blocked by dirt or its capacity is too small, resulting in increase in inhaled air oil resistance; in addition,inlet, outlet of large caliber may also into the air. At this time, can clean the oil filter, or select a larger capacity,and import oil strainer aperture appropriate. Three screw pump can not only prevent inhalation of air, but also prevent the generation of noise.
油箱內(nèi)油量不夠,或吸油管口未插至油面以下,泵便會(huì)吸入空氣,此時(shí)應(yīng)往油箱內(nèi)增補(bǔ)油液至油標(biāo)線;若回油管口露出油面,有時(shí)也會(huì)因系統(tǒng)內(nèi)瞬間負(fù)壓而使空氣反灌進(jìn)入系統(tǒng),所以回油管口一般也應(yīng)插至油面以下。
The amount of oil in the tank is not enough, or the suction nozzle is not inserted into the oil, pump will be inhaled air, at this time should go to the tank added oil to oil line; if the oil return pipe exposed out of the oil surface,sometimes as a result of system pressure and make the air moment in anti poured into the system, so the oil return pipe generally should be inserted the following to the oil surface.
三螺桿泵的泵體與兩側(cè)端蓋為直接接觸的硬密封,若接觸面的平面度達(dá)不到劃定要求,則泵在工作時(shí)輕易吸入空氣;同樣,泵的端蓋與壓蓋之間也為直接接觸,空氣也輕易侵入;若壓蓋為塑料制品,因?yàn)槠鋼p壞或因溫度變化而變形,也會(huì)使密封不嚴(yán)而進(jìn)入空氣。排除這種故障的方法是:當(dāng)泵體或泵蓋的平面度達(dá)不到劃定的要求時(shí),可以在平板上用金鋼砂按字形路線往返研磨,也可以在平面磨床上磨削,使其平面度不超過(guò)5μm,并需要保證其平面與孔的垂直度要求;對(duì)于泵蓋與壓蓋處的泄漏,可采用涂敷環(huán)氧樹脂等膠粘劑進(jìn)行密封。
Hard sealing end of the pump body and cover both sides of the three screw pump for direct contact, if the contactplane is not up to the designated requirements, are easily inhaled air pump at work; similarly, the pump cover andthe cover for the direct contact between, the air also easily invade; if the gland is a plastic products, because thedamage or deformation due to temperature changes, also can make the sealing lax and into the air. Method toeliminate this failure is: when the plane of the pump or pump cover degree is not up to the requirementsdelineated, can at the plate with steel sand in the zigzag route round grinding, can also be grinding on a surfacegrinder, the flatness is less than 5 m, and the need to ensure the verticality of the plane with holes the pumpcover and leakage; the cover, can be coated with epoxy resin adhesive seal
The framework oil seal pump shaft seal. Spring Rocca tight lip off, or anti oil package, or lips were strained, aging,will make oil seal is often in the state of negative pressure air inhaled, can be replaced with new oil seal to solve
泵軸一般采用骨架式油封進(jìn)行密封。若卡緊唇部的彈簧脫落,或?qū)⒂头庋b反,或其唇部被拉傷、老化,都將使油封后端常常處于負(fù)壓狀態(tài)而吸入空氣,一般可更換新油封予以解決

新旋轉(zhuǎn)窯*次點(diǎn)火必須采用SMH80和SMH120,SMH210點(diǎn)火油泵噴射霧化燃燒點(diǎn)火及掛窯皮期間的操作方法
1.窯頭點(diǎn)火升溫
1.1 窯頭點(diǎn)火
現(xiàn)代化的預(yù)分解窯,窯頭都采用三風(fēng)道或四風(fēng)道燃燒器,噴嘴中心都設(shè)有點(diǎn)火裝置。新窯*次掛窯皮,使用輕柴油點(diǎn)火油泵SMH80R46E6.7W23和SMH120R42E6.7W23系列高壓三螺桿泵,大型和超大型旋轉(zhuǎn)窯一般采用SMH210R40E6.7W29點(diǎn)火油泵點(diǎn)火,其點(diǎn)火壓力可以達(dá)到5Mpa。因?yàn)檫@樣點(diǎn)火,柴油燃料在高壓力下霧化效果好而且非常充分,燃燒就更加充分,保證了油煤混合燃燒,用煤量少,火焰溫度高,煤粉燃盡率也高。如果用木材點(diǎn)火,火焰溫度低,初期噴出的煤粉只有揮發(fā)分和部分固定碳燃燒。煤粉中大部分固定碳未燃盡就在窯內(nèi)沉降。而且木材燃燒后留下大量木灰,這些煤灰和木灰在高溫作用下被燒融,粘掛在耐火磚表面,不利于粘掛*、堅(jiān)固、結(jié)實(shí)和穩(wěn)定的窯皮。窯頭點(diǎn)火一般用浸油的棉紗包綁在點(diǎn)火棒上,點(diǎn)燃后置于噴嘴前下方,隨后即刻噴油。待窯內(nèi)溫度稍高一些后開始噴人少量煤粉。在火焰穩(wěn)定、棉紗包也快燒盡時(shí),抽出點(diǎn)火棒。以后隨著用煤量的增加,火焰穩(wěn)定程度的提高,逐漸減少輕柴油的噴人量,直至全部取消。在此期間,窯尾溫度應(yīng)遵循升溫曲線要求緩慢上升。在RSP型分解爐上,為使RSP分解爐渦流分解室有足夠的溫度加速煤粉的燃燒,窯頭點(diǎn)火前應(yīng)將2個(gè)C4旋風(fēng)筒排灰閥桿吊起。這樣,窯尾部分高溫廢氣可以進(jìn)入渦流分解室經(jīng)排灰閥、下料管人C4旋風(fēng)筒,對(duì)渦流分解室起到預(yù)熱升溫的作用。
1.2 升溫曲線和轉(zhuǎn)窯制度
系統(tǒng)從冷態(tài)窯點(diǎn)火升溫到開始掛窯皮期間窯尾廢氣溫度、C5出口溫度和C1出口溫度以及不同溫度段的轉(zhuǎn)窯制度。當(dāng)窯尾廢氣溫度約為750—800℃時(shí),啟動(dòng)生料喂料系統(tǒng),向窯內(nèi)喂入5%左右的設(shè)計(jì)喂料量,為掛好窯皮創(chuàng)造條件。
2.投料掛窯皮
當(dāng)預(yù)熱器系統(tǒng)充分預(yù)熱,窯尾溫度達(dá)950℃左右,這時(shí)分解爐渦流分解室溫度可達(dá)650—700℃,窯頭火磚開始發(fā)亮發(fā)白時(shí),早先喂人的幾噸生料也即將進(jìn)入燒成帶。這時(shí),窯頭留火待料,保持燒成帶有足夠高的溫度,并將吊起的2個(gè)C4排灰閥復(fù)原。三次風(fēng)管閥門開至10%左右,打開渦流燃燒室和分解室閥門,開始向渦流分解室噴輕柴油和少量煤粉。當(dāng)C1出口溫度達(dá)400—450℃時(shí),打開置于C1出口至高溫風(fēng)機(jī)廢氣管道上的冷風(fēng)閥,摻人冷風(fēng)調(diào)節(jié)廢氣溫度,保護(hù)高溫風(fēng)機(jī)。待C5出口溫度達(dá)900℃時(shí),適當(dāng)開大三次風(fēng)管閥門后即可下料。喂料量為設(shè)計(jì)能力的30%-40%。喂料后逐漸關(guān)閉冷風(fēng)閥,適當(dāng)加大喂煤量和系統(tǒng)排風(fēng)量,窯以較低的轉(zhuǎn)速(如0.3—0.6r/min)連續(xù)運(yùn)轉(zhuǎn)并開始掛窯皮。當(dāng)系統(tǒng)比較正常,分解爐溫度穩(wěn)定后,就可以撤除點(diǎn)火噴油嘴。如果系統(tǒng)燒無(wú)煙煤,則應(yīng)適當(dāng)延長(zhǎng)點(diǎn)火噴嘴的使用時(shí)間,但油量可以減少,以對(duì)無(wú)煙煤起助燃作用。
掛好窯皮是延長(zhǎng)燒成帶火磚壽命,提高回轉(zhuǎn)窯運(yùn)轉(zhuǎn)率的重要環(huán)節(jié)。其關(guān)鍵是掌握火候,待生料到達(dá)燒成帶時(shí)及時(shí)調(diào)整燃料量和窯速,確保穩(wěn)定的燒成帶溫度。窯速與喂料量相適應(yīng),使粘掛的窯皮厚薄*、平整、均勻、堅(jiān)固。掛窯皮期間嚴(yán)防燒成帶溫度驟變。溫度太高,掛上的窯皮易被燒垮,生料易燒流,在窯內(nèi)“推車”會(huì)嚴(yán)重磨蝕耐火磚;溫度突然降低會(huì)跑生料,形成疏松夾心窯皮,極易塌落,影響窯皮質(zhì)量。
掛窯皮時(shí)間,一般約需3—4個(gè)班。窯皮掛到一定程度以后,生料喂料量可以3-5t/h的速度增加,直至100%的設(shè)計(jì)能力。窯速和系統(tǒng)排風(fēng)也隨燃料和生料喂料量的增加而逐漸加大.
