SMH80R46E6.7W28三螺桿泵、重油輸送泵
如何進行三螺桿泵配套機械密封的更換安裝,必須遵循以下幾點:
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械密封件標識標志,質量是否符合標準;密封安裝前,應確認產品型號及規(guī)格與設備要求*。
(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)尾部防轉槽端與防轉銷頂部應保持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,仔細檢查務必保證動、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”形橡膠密封圈應涂上機械密封標準一層潤滑油膏,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、或介質不允許注入潤滑油的情況下,可涂抹植物油或肥皂水。把機械密封套上軸,按設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)聯接擰緊機械密封配有輔助系統(tǒng)時,按標示正確連接管路。
(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)在三螺桿泵轉子與泵體的相對位置固定之后,確定機械密封的安裝位置,根據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,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械密封,注意觀察轉矩的變化,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,密封腔內通入密封介質,全部排出密封腔的空氣,使密封腔中全部充滿介質,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)確認上述兩項正確無誤后進行試運轉。
(11) confirmed that the above two correct test run.
(12)機械密封腐蝕防護知識詳解
(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,而金屬本身又不耐腐蝕,就會產生表面腐蝕,其現象是泄漏、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,稱為應力腐蝕破裂,選用堆焊硬質合金及鑄鐵、碳化鎢、碳化鈦等密封環(huán),容易出現應力腐蝕破裂。腐蝕過程以一定的速度進行,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)應力腐蝕破裂。金屬在腐蝕和拉應力的同時作用下,耐磨性。機械密封填充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.
點火燃油泵的安全使用及維護
Ignition of safe use and maintenance of the fuel pump
安裝漏電保護器
1, the installation of leakage protector
漏電保護器也叫保命器,它的作用從“保命器”這三個字就可以理解。因為點火燃油泵在油下工作,容易漏電造成電能損失甚至引發(fā)觸電事故。如果裝有漏電保護器,只要點火燃油泵漏電值超過漏電保護器的動作電流值(一般不超過30毫安),漏電保護器就會切斷點火燃油泵的電源,避免漏電浪費電能,確保安全。
Leakage protector, also known as life insurance, it can be understood from the "this three word life insurance".Because the ignition fuel pump in oil, easy to leakage caused by power loss or even lead to electric shock. If there is a leakage protector, as long as the ignition fuel pump leakage exceeds the action leakage protection current value (generally not more than 30 MA), electric leakage protection device will cut off the ignition of the fuel pumppower, to avoid wasting electricity leakage, to ensure safety.
電源電壓異常莫開機
2, Mo power supply voltage abnormality
農村由于低壓供電線路比較長,線路的末端電壓過低是常有的事。當相電壓低于198伏,線電壓低于342伏時,點火燃油泵電機轉速下降,當達不到額定轉速的70%時,啟動離心開關會閉合,造成啟動繞組長時間通電而發(fā)熱甚至燒壞繞組和電容器。相反,電壓過高引起電機過熱而燒壞繞組。因此,點火燃油泵在作業(yè)中,操作者必須隨時觀察電源電壓值,若低于額定電壓10%以下,高于額定電壓10%以上,應使電機停止運轉,找出原因并排除故障。
Low-voltage power lines in rural areas as long, terminal voltage is low line is constant some thing. When the phase voltage below 198 volts, the line voltage is lower than 342 volts, the ignition fuel pump motor speed down,when up to 70% less than the rated speed, the centrifugal start switch closed, resulting in start winding electricityand heat and even burn winding and capacitor. On the contrary, caused by high voltage motor overheating and burn winding. Therefore, the ignition of fuel pump in operation, the operator must always observe the power supply voltage value, if less than the rated voltage below 10%, higher than the rated voltage above 10%, should the motor stop running, find out the reasons and troubleshooting.
莫讓點火燃油泵*超負荷工作
3, do not let the ignition fuel pump overload
為避免潛油電泵*超負荷工作,不要抽含沙量大的油并隨時觀察電流值是否在銘牌上規(guī)定的數值,若發(fā)現電流過大,應停機檢查。另外,電泵脫油運行的時間不宜過長,以免使電機過熱而燒毀。
In order to avoid the electric submersible pump long-term overload of work, numerical do not draw large sedimentoil and observe whether the current value specified on the nameplate, if too much current is found, should be down to check. In addition, the electric pump oil removing operation time should not be too long, to avoid overheating and burning motor.
避免頻繁開關
4, to avoid frequent switching
不要頻繁地開關點火燃油泵,這是因為電泵停轉時會產生回流,若立即開機,會使電機負載啟動,導致啟動電流過大而燒壞繞組。由于啟動時電流很大,頻繁啟動也會燒壞點火燃油泵電動機繞組。
The ignition of fuel pump do not frequently switch, this is because the pump will stop to have a return, if an immediate start, will start the motor load, resulting in excessive starting current and burn winding. As the start when the current large, frequent starts will burn the fuel pump motor ignition winding.
Insulation resistance
電纜線安裝與潛油電泵的絕緣電阻要求
5, cable installation and electric submersible pump
安裝點火燃油泵時,電纜線要架空,電源線不要太長。點火燃油泵下油或提出時切勿使電纜受力,以免引起電源線斷裂。點火燃油泵工作時不要沉入泥中,否則會導致電機散熱不良而燒壞電機繞組。安裝時,電機的絕緣電阻不應低于0.5兆歐。
Install ignition fuel pump, to the overhead cable, power line should not be too long. Ignition fuel pump oil or propose not to force the cable, so as not to cause a power line fault. Ignition fuel pump work do not sink into the mud, or would result in poor motor cooling motor windings burned. When in installation, insulation resistanceshould not be less than 500000000000 ohm motor.
電機的旋轉方向要正確
The direction of rotation, the motor 6 to the right
應搞清電機的旋轉方向,現在有許多類型的點火燃油泵正轉和反轉時皆可出油,但反轉時出油量小、電流大,其反轉時間長了會損壞電機繞組。
We should understand the direction of motor rotation, there are many types of ignition of fuel pump when the forward and reverse can be out of oil, but the reverse when the oil quantity is small, current, its reversal long time may damage the motor windings.
勤查勤看發(fā)現問題及時修復
7, Qin Chaqin see repair problems in a timely manner
平時要經常檢查電機,如發(fā)現下蓋有裂紋、橡膠密封環(huán)損壞或失效等,應及時更換或修復,避免油滲入點火燃油泵。
Usually should always check the motor, such as a crack was found under the lid, rubber seal ring damage or failure, should be timely replacement or repair, oil into the ignition fuel pump to avoid.
