SMH120R46E6.7W30三螺桿泵、臥式SM系列冷卻液輸送泵
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、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、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、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，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)封動環(huán)，動環(huán)安裝后須保證能其在軸上靈活移動。
（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，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.
