　　選用泵的規(guī)格是根據(jù)被輸送液體的性質(zhì)和流量、壓力來決定的，而泵的轉(zhuǎn)速則由輸送液體的粘度和腐蝕性、作為主要參數(shù)來選擇，才能保證泵可靠運行。Choose the specifications of the pump is according to the nature of the liquid to be delivered and decide the flow, pressure, while the pump speed by conveying liquid viscosity and corrosive, as the main parameter to select, to ensure the pump running.泵的設(shè)計轉(zhuǎn)速為輸送清水或清水相類似的無腐蝕性液體時允許 高轉(zhuǎn)速，在實際使用中因介質(zhì)性質(zhì)與壽命要求不同，選用時一般都應(yīng)低于設(shè)計轉(zhuǎn)速。Design speed of pump for conveying water or similar without corrosive liquid to allow the highest speed in the water, in be used actually due to the different requirements, dielectric properties and service life when choosing generally should be lower than design speed.對高粘度和含顆粒介質(zhì)，一般采用設(shè)計轉(zhuǎn)速的1/2-1/3 或更低些，低轉(zhuǎn)速對泵的磨損有利，但在使用后由于定子的磨損流量下降，這時可適當提高轉(zhuǎn)速，以補償流量下降也為常策。For high viscosity and particle medium, generally USES the design speed 1/2 - a third or more lower, low speed of pump wear and tear, but after use due to the wear and tear of the stator flow down, then can be appropriately increased speed, to compensate for declining to often.輸送介質(zhì)的溫度應(yīng)在 -10 ℃～80℃特殊情況可高達120℃。The temperature of the medium should be - 10 ℃ ~ 80 ℃ special circumstances can be as high as 120 ℃.

??? 泵的每級（定子的一個導程）正常壓力為 0.6Mpa，短時間（不超過30分鐘）內(nèi)允許高達0.8Mpa，當磨損后在相同輸出壓力時的容積效率要逐步下降。Pump per level (lead) of the stator of a normal pressure is 0.6 Mpa, inside short time (less than 30 minutes) to allow up to 0.8 Mpa, when after wear and tear on the e output pressure volumetric efficiency will decline gradually.泵送清水時 高吸程為 8米，實際使用建議不超過6.5米，當泵送高粘度介質(zhì)時，應(yīng)以正壓吸入。When pumping water to the highest suction is 8 meters, the actual use suggest no more than 6.5 meters, when pumping high viscosity medium, the positive pressure breathing.

??? 單螺桿泵使用過程中故障及解決方法Single screw pump failure in use process and solving methods

?????? 1、桿斷脫:由于單螺桿泵抽油桿負荷過大、磨損或誤操作等原因，引起抽油桿斷裂，脫扣或擼扣的情況，具體表現(xiàn)為：在短期內(nèi)，泵效大幅度下降，動液面迅速上升，電流下降甚至接近空載電流。1, the rod break off: due to the large single screw pump rod load, wear or wrong operation and so on reasons, lead to sucker rod breaking, tripping or lu buckle, embodied in: in the short term, pump efficiency drops sharply, the working fluid level rising rapidly, current decline or even close to the no-load current.扭矩和軸向力仍為平穩(wěn)直線，但由于缺少了井下泵的工作扭矩，光桿扭矩值遠小于正常工作范圍，軸向力缺少了液壓力對轉(zhuǎn)子產(chǎn)生的軸向力，因此也小于正常范圍，根據(jù)斷脫部位，桿柱自重產(chǎn)生的軸向力不同，據(jù)此可計算出桿柱斷脫深度。Torque and axial force is still as smooth as a straight line, but the lack of the downhole pump working torque, polished rod torque value is far less than the normal scope of work, the axial force without the fluid pressure of the axial force produced by the rotor, which is less than the normal range, according to the broken parts, rod string axial force produced by self weight, can calculate the depth of the rod string break off accordingly.

?? 2、泵漏失:由于單螺桿泵的定子橡膠磨損，造成定轉(zhuǎn)子過盈減小，泵承壓能力下降。And leakage of pump, 2: as a result of the single screw pump stator rubber wear, cause stator interference is reduced, the pump pressure can drop.因此，漏失量增加。Therefore, the loss increased.具體表現(xiàn)為：泵效逐漸下降，動液面逐漸上升，電流逐漸下降。Specific performance is: the pump efficiency is falling, working fluid level is gradually rising, the current gradually decreases.由于漏失量加大，泵有功扭矩下降，扭矩低于正常范圍。Decline because of the increase amount of leakage, pump active torque, torque is lower than the normal range.由于液壓力產(chǎn)生的軸向力下降，軸向力低于正常范圍，但仍大于桿柱在采出液中的重量。The axial force generated in the fluid pressure drop, axial force is lower than the normal range, but still greater than the rod string weight in produced fluid.

??? 3、定子溶脹:由于采出液的作用。3, stator swelling: due to the effect of produced fluid.單螺桿泵的定子橡膠發(fā)生溶脹，造成定轉(zhuǎn)子過盈增加，泵效和動液面正常，電流增加，由于過盈大，定轉(zhuǎn)子的初始扭矩增加，因此光桿扭矩增加，超過正常范圍，嚴重時會造成定轉(zhuǎn)子抱死，但軸向力正常。Single screw pump stator rubber swelling occurs, causing rotor interference increase, pump efficiency and working fluid level is normal, current is added, due to the interference, rotor initial torque increase, so the polished rod torque increase, more than the normal range, serious will cause the rotor, holding in death of the set, but normal axial force.??? 4、定子脫膠:定子脫膠是由于定子粘接強度不夠造成。4, stator degumming: stator degumming is caused by the stator bonding strength is not enough.表現(xiàn)形式為泵效急劇下降，動液面上升，電流下降并波動。A sharp drop in form of pump efficiency, dynamic liquid level rise, current decline and volatility.脫膠時，泵有功扭矩為零，光桿扭矩下降很大。Degumming, pump active torque is zero, the polished rod torque decreased a lot.另外，由于脫膠后定轉(zhuǎn)子之間發(fā)生不規(guī)則摩擦。In addition, because after degumming with irregular friction between stator.光桿扭矩會出現(xiàn)不規(guī)則液動。Polished rod torque will be irregular hydraulic.液壓力產(chǎn)生的軸向力為零，因此，光桿軸向力低于正常范疇，但仍高于桿柱在采出液的重量。Axial force produced by hydraulic pressure is zero, therefore, the polished rod axial force is lower than the normal category, but still higher than the weight of the rod string in the produced fluid.

??? 5、管漏失:管漏失是由于油管壁上存在裂縫造成的。5, pipe leakage, leakage of tube is caused by the tubing wall cracks exist.現(xiàn)象為泵效下降，動液面上升，電流減小。Phenomenon of pump efficiency drops, working fluid level rise, current decreases.由于單螺桿泵工作壓差減小，泵有功扭矩下降，光桿扭矩低于正常范圍，液壓力產(chǎn)生的軸向力減小，光桿軸向力略低于正常范圍，但仍高于桿柱在液體中的重量。By the pumping action of the single screw pump working pressure differential is reduced, active torque, polished rod torque is lower than the normal range, the axial force produced by hydraulic pressure decreases, and polished rod axial force is slightly lower than the normal range, but still higher than that of rod string weight in liquid.這是單螺桿泵在抽井中的油時常遇到的故障類型，在使用時一定要注意。This is single screw pump in oil Wells in the fault types often encountered, it is important to note that when using.
