　　选用泵的规格是根据被输送液体的性质和流量、压力来决定的，而泵的转速则由输送液体的粘度和腐蚀性、作为主要参数来选择，才能保证泵可靠运行。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.泵的设计转速为输送清水或清水相类似的无腐蚀性液体时允许高转速，在实际使用中因介质性质与寿命要求不同，选用时一般都应低于设计转速。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.对高粘度和含颗粒介质，一般采用设计转速的1/2-1/3 或更低些，低转速对泵的磨损有利，但在使用后由于定子的磨损流量下降，这时可适当提高转速，以补偿流量下降也为常策。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.输送介质的温度应在 -10 ℃～80℃特殊情况可高达120℃。The temperature of the medium should be - 10 ℃ ~ 80 ℃ special circumstances can be as high as 120 ℃.

泵的每级（定子的一个导程）正常压力为 0.6Mpa，短时间（不超过30分钟）内允许高达0.8Mpa，当磨损后在相同输出压力时的容积效率要逐步下降。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.泵送清水时高吸程为 8米，实际使用建议不超过6.5米，当泵送高粘度介质时，应以正压吸入。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.

    单螺杆泵使用过程中故障及解决方法Single screw pump failure in use process and solving methods

       1、杆断脱:由于单螺杆泵抽油杆负荷过大、磨损或误操作等原因，引起抽油杆断裂，脱扣或撸扣的情况，具体表现为：在短期内，泵效大幅度下降，动液面迅速上升，电流下降甚至接近空载电流。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.扭矩和轴向力仍为平稳直线，但由于缺少了井下泵的工作扭矩，光杆扭矩值远小于正常工作范围，轴向力缺少了液压力对转子产生的轴向力，因此也小于正常范围，根据断脱部位，杆柱自重产生的轴向力不同，据此可计算出杆柱断脱深度。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:由于单螺杆泵的定子橡胶磨损，造成定转子过盈减小，泵承压能力下降。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.具体表现为：泵效逐渐下降，动液面逐渐上升，电流逐渐下降。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，扭矩低于正常范围。Decline because of the increase amount of leakage, pump active torque, torque is lower than the normal range.由于液压力产生的轴向力下降，轴向力低于正常范围，但仍大于杆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、定子溶胀:由于采出液的作用。3, stator swelling: due to the effect of produced fluid.单螺杆泵的定子橡胶发生溶胀，造成定转子过盈增加，泵效和动液面正常，电流增加，由于过盈大，定转子的初始扭矩增加，因此光杆扭矩增加，超过正常范围，严重时会造成定转子抱死，但轴向力正常。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、定子脱胶:定子脱胶是由于定子粘接强度不够造成。4, stator degumming: stator degumming is caused by the stator bonding strength is not enough.表现形式为泵效急剧下降，动液面上升，电流下降并波动。A sharp drop in form of pump efficiency, dynamic liquid level rise, current decline and volatility.脱胶时，泵有功扭矩为零，光杆扭矩下降很大。Degumming, pump active torque is zero, the polished rod torque decreased a lot.另外，由于脱胶后定转子之间发生不规则摩擦。In addition, because after degumming with irregular friction between stator.光杆扭矩会出现不规则液动。Polished rod torque will be irregular hydraulic.液压力产生的轴向力为零，因此，光杆轴向力低于正常范畴，但仍高于杆柱在采出液的重量。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缝造成的。5, pipe leakage, leakage of tube is caused by the tubing wall cracks exist.现象为泵效下降，动液面上升，电流减小。Phenomenon of pump efficiency drops, working fluid level rise, current decreases.由于单螺杆泵工作压差减小，泵有功扭矩下降，光杆扭矩低于正常范围，液压力产生的轴向力减小，光杆轴向力略低于正常范围，但仍高于杆柱在液体中的重量。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.这是单螺杆泵在抽井中的油时常遇到的故障类型，在使用时一定要注意。This is single screw pump in oil Wells in the fault types often encountered, it is important to note that when using.
