SMH40R54E6.7W30三螺桿泵、重油輸送泵、高壓油泵
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5μm,并需要保證其平面與孔的垂直度要求;對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
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
如何進(jìn)行三螺桿泵配套機(jī)械密封的更換安裝,必須遵循以下幾點(diǎn):
How to replace the three screw pump mechanical seal installation, the following points must be observed:
(1)螺桿泵出廠序列號、機(jī)械密封的型號、規(guī)格是否正確以及是否為帶有黃山天曼泵業(yè)有限公司三螺桿泵機(jī)械密封件標(biāo)識標(biāo)志,質(zhì)量是否符合標(biāo)準(zhǔn);密封安裝前,應(yīng)確認(rèn)產(chǎn)品型號及規(guī)格與設(shè)備要求*。
(1) the screw pump mechanical seal factory serial number, type, specification is correct and whether with Mount Huangshan teamon pump industry limited company machinery three screw pump seal logo, quality standards;seal before installation, should confirm the product types and specifications and equipment requirements.
(2)靜環(huán)尾部防轉(zhuǎn)槽端與防轉(zhuǎn)銷頂部應(yīng)保持1mm-2mm的軸向間隙,以免緩沖失效。
(2) the static ring tail anti rotary slot end and the anti rotation pin top should maintain the axial clearance of 1mm-2mm, so as to avoid the buffer invalidation.
(3)動(dòng)、靜環(huán)端面用酒精清洗干凈,其余金屬件用汽油清洗并用潔凈的壓縮空氣吹干,仔細(xì)檢查務(wù)必保證動(dòng)、靜環(huán)密封面沒有任何損傷。損傷和破裂的均不能更換。裝配前,兩件“O”形橡膠密封圈應(yīng)涂上機(jī)械密封標(biāo)準(zhǔn)一層潤滑油膏,動(dòng)、靜環(huán)端面不許涂油。
(3) dynamic, static ring tip with alcohol to clean, and other metal parts cleaning with gasoline and clean compressed air dryer, carefully check must ensure that the dynamic, static ring sealing surface without anydamage. Damage and can not be broken replacement. Before the assembly, the two "O" shaped rubber sealing ring should be coated with a layer of lubricating grease standard mechanical seal, dynamic, not static ring oiler.
(4)在安裝密封的軸,腔體及壓蓋等與輔助密封圈接觸處均勻涂油(注:對乙丙橡膠、或介質(zhì)不允許注入潤滑油的情況下,可涂抹植物油或肥皂水。把機(jī)械密封套上軸,按設(shè)計(jì)的工作高度安裝到位。過壓蓋通孔,采用對角線交叉擰緊方式,用螺栓將整個(gè)密封與密封腔體(泵蓋)聯(lián)接擰緊機(jī)械密封配有輔助系統(tǒng)時(shí),按標(biāo)示正確連接管路。
(4) in the installation of the sealing shaft, cavity and a gland and auxiliary seal ring contact uniform oiling (Note:ethylene propylene rubber, or the media are not allowed into the lubrication condition, can apply vegetable oil orsoap and water. The mechanical sealing sleeve shaft, according to design the working height of the installed in place. Overvoltage cover through hole, the diagonal cross screw, bolt the entire seal and seal cavity (cover)connected tighten the mechanical seal fitted with auxiliary system, marked by the pipeline connecting the right.
(5)在三螺桿泵轉(zhuǎn)子與泵體的相對位置固定之后,確定機(jī)械密封的安裝位置,根據(jù)密封的安裝尺寸及靜環(huán)在壓蓋中的位置,測算出密封在軸或軸套上的定位尺寸。
(5) after the relative positions of the three screw pump rotor and pump body is fixed, to determine the installation position of mechanical seal, according to the size and position of the installation of sealing static ring in the gland,calculate the location dimension seal in the shaft or shaft sleeve.
(6)安裝機(jī)封動(dòng)環(huán),動(dòng)環(huán)安裝后須保證能其在軸上靈活移動(dòng)。
(6) mounted machine sealing ring, ring after installation shall ensure that its flexible move on the shaft.
(7)將組裝好的靜環(huán)部分和動(dòng)環(huán)部分組裝好。
(7) the assembled static ring and moving ring partially assembled.
(8)把密封端蓋裝在密封體內(nèi),并將螺絲擰緊。
(8) the sealing end cover is arranged in the sealing body, and the screw.
(9)試車:以上步驟完成后,手動(dòng)盤車三螺桿泵配套機(jī)械密封,注意觀察轉(zhuǎn)矩的變化,以及有無擦碰聲音異常等,以確定是否要重新安裝和調(diào)整。
(9) test: after the above steps, manual turning three screw pump mechanical seal, observe the torque change,and there is no rubbing sound abnormal, to determine whether to re install and adjust.
(10)打開閥門,密封腔內(nèi)通入密封介質(zhì),全部排出密封腔的空氣,使密封腔中全部充滿介質(zhì),并觀察封有無泄漏情況。
(10) to open the valve, the sealing cavity communicated with the sealing medium, exhaust all the seal cavity of the air, so that the sealing cavity full of medium, and observe the seal without leakage.
(11)確認(rèn)上述兩項(xiàng)正確無誤后進(jìn)行試運(yùn)轉(zhuǎn)。
(11) confirmed that the above two correct test run.
(12)機(jī)械密封腐蝕防護(hù)知識詳解
(12) the mechanical seal corrosion protection knowledge.
(13)表面均勻腐蝕。如果金屬環(huán)表面接觸腐蝕介質(zhì),而金屬本身又不耐腐蝕,就會(huì)產(chǎn)生表面腐蝕,其現(xiàn)象是泄漏、早期磨損、破壞、發(fā)聲等。金屬表面均勻腐蝕有成膜和無膜兩種形態(tài),無膜的金屬腐蝕很危險(xiǎn),稱為應(yīng)力腐蝕破裂,選用堆焊硬質(zhì)合金及鑄鐵、碳化鎢、碳化鈦等密封環(huán),容易出現(xiàn)應(yīng)力腐蝕破裂。腐蝕過程以一定的速度進(jìn)行,使電偶腐蝕加劇?!?/p>
(13) surface uniform corrosion. If the metal contact ring corrosive medium, and the corrosion of the metal itself is intolerant, it will have a surface corrosion, which is leaking, the early wear and tear, damage, such as audible.Uniform corrosion on metal surfaces have two forms of film and without film, corrosion of metal membrane free is dangerous, known as stress corrosion cracking, the selection of welding hard alloy and cast iron, tungsten carbide, titanium carbide seal ring, prone to stress corrosion cracking. The corrosion process to a certain speed,so that aggravate galvanic corrosion.
(14)應(yīng)力腐蝕破裂。金屬在腐蝕和拉應(yīng)力的同時(shí)作用下,耐磨性。機(jī)械密封填充F4環(huán)的腐蝕主要是指填充的選擇性腐蝕、溶出或變質(zhì)破壞。如在氫氟酸中,玻璃纖維分子熱腐蝕,這些裂縫溝通了整個(gè)密封端面,加速了端面的磨損,使泄漏量增加。
14) the stress corrosion cracking. Metal corrosion and stress at the same time, wear resistance. Corrosion of mechanical seal ring filled F4 mainly refers to the selective corrosion, filled stripping or destruction of metamorphism. Such as hydrofluoric acid, the hot corrosion of glass fiber elements, these cracks sealed face communication as a whole, to speed up the end of the wear and tear, so that leakage increased.
