3、分发挥其效用,改善钻井液性能,如果没有充分剪切,聚合物在第一次循环中就可能堵塞振动筛网,损失大量的聚合物,增加钻井成本,并且还可能使钻井液中的大尺寸的固相颗粒变硬而难以除掉;在完井液中,由于没有充分剪切,聚合物会产生许多“鱼眼” 。这些“鱼眼”会伤害地层,使地层渗透率降低,油气层减产。经过事实证明 WJQ56J-10剪切泵具有优良的性能,它能为高分子聚合物(也能为粘土)迅速水合提供高度的剪切,解决聚合物(或粘土)在钻井液中或完井液中因水合不好而存在的突出问题。同时,使用 WJQ56J-10剪切泵能使聚合物用量减少 15%以上,膨润土用量减少 30%以上,并且改善了泥饼和液流损失,降低钻井液剪切

4、比速率,提高凝胶强度,达到了国外同类产品的先进水平,其轴封结构更可靠,使用维护更方便。2原理WJQ56JC-10剪切泵密封采用了非常可靠的机械密封,保证无泄漏。泵内部配有一个 300mm 不锈钢涡轮(其上有导叶、叶轮、44 个喷嘴、4 个收集室) ,及一个剪切板,能够产生超过 25.4m/s 的小端剪切(液体剪切) ,当液流通过剪切泵时,有一半(50%)的液体在涡轮收集室的强力推进下将被4剪切两次。该涡轮剪切泵安装在一专用底座上,并用皮带轮、窄 V 带和 55KW/75kw 防爆电动机驱动,与剪切泵配套使用的还有一个尺寸适合的 ZHP150 混合漏斗,这样组成了一个完善的剪切及水合作用系统。由

5、于该泵轴封的改进,使其寿命大大提高。如遵循该泵安装及特殊条件应用的规则,将进一步提高其性能。本公司将对在油田及工业应用中有利于提高该泵性能的一般及特殊建议进行处理。注意:该泵不能用于活性泥浆系统,因为系统中的钻井固体及重晶石,它们在受到剪切时将很快损坏该泵。原理如图一:图一 WJQ56JC-10剪切泵原理图5聚合物流体从 V 流道进入,并以平行与剪切板 P 的方向抽送,收集室内液流量的 50%通过 44 个喷嘴 N 射出,并以高速冲击剪切板 P,然后在 M 处 90方向进入泵的蜗壳收集室。总流 V 及射流 N 沿着剪切板流动到达剪切盘的尖端 T,在尖端有许多牙齿,高速旋转的牙齿使聚合物(或粘土

11、不得超过 2mm。B.皮带必须找正、绷紧。C.电机安装必须平稳、牢固。6.3.3 进口管路安装A.吸入管路截面积必须大于或等于泵流道断面积。B.吸入管路中不允许安装节流阀,但可以安装常开阀以减少液流紊乱,该阀只能在拆泵进行检修时才能关闭。12C.为避免吸入管路中产生汽泡,抽送源和泵之间应从高到低逐渐过渡。如果用户需要泵在有吸程状况下使用,请采用真空泵或底阀引水。D泵入口处的管路必须平直,其长度至少为吸入管路直径的二倍。E当临时使用软管吸入管路时,必须保证软管不被压缩,这是因为吸入段管内压力一般都比大气压低,在大气压作用下,软管被压缩,从而导致流量降低甚至断流。6.3.4 出口管路A为便于泵的检

12、修,出口管路中应该安装常开阀。B所有管路(包括入口管路)必须有自己的支撑,绝不允许由泵承受管路重量。C当工作条件不明或不稳定时,出口管路中必须安装节流阀,以保证泵在设计点运行。D当泵出口与压力设备相接时,在节流阀和泵出口之间必须安装止回阀,以防止液体回流,否则,回流液会导致泵发生“水锤现象”而损坏。6.4 使用6.4.1 准备A用手转动泵轴,必须保证运转灵活,各处不得有摩擦声。B检查转向,必须确保与泵体所示转向一致。C全开入口段的阀门。D给泵体和入口段管路注满液体,以排出空气。6.4.2 运转操作A 准备工作全部结束后,开动电机。6.4.3 润滑13A 轴承润滑a 轴承采用 30 号机油润滑,

13、润滑油应加至油标的中线,不要加过多油,否则将导致轴承振动和过热。每 90 天或 1000 小时换油一次。b 在特殊情况下,轴承可用与润滑油相容的润滑脂润滑。B 填料腔润滑a 填料腔必须经常润滑,以防止填料过热而损坏,一般要求每天至少一次。b 注入润滑脂时必须旋转泵轴,以使其充分进入填料腔,直到填料压盖端有油脂渗出为止。6.5 维护(参照图三及零件明细表 2)A 拆卸:a 拆下皮带轮组件。b 拆下填料压板组件(26) 。c 卸下泵壳(1) 。d 拆除叶轮组件(2) 、剪切板(3) 、加强板(4):先拆下螺母(33、34) (螺母为反扣)及垫圈(35) ,注意如无叶轮扳手,则用木制垫块和木榔头敲击

IntroductionThe WJQ5 6J-10 shear pump generation is uniquely designed pump for shearing polymers and clays.To improve the drill fluid properties, the polymers or clays should be highly sheared before adding them to the drill flui

21、d system. If not sheared, the polymers maybe jam the strainer and will result in losing amount of polymer and increasing drilling costs, and the large-size solids in the drill fluid will harden and difficult to clear away as well. The WJQ5 6J-10 shear pump has proven best for applying the high shear

22、 necessary to hydrate polymers and clays and to their best properties. Using the WJQ56J-10 shear pump reduces the bentonite clay needed by 33% or more and polymer needed by 15% or more. It also improve fluid loss and filter cake, builds gel strength, and low shear rate viscosity to better hold up so

23、lids. With reliable shaft seal structure and more convenient in operation and maintenance, it comes up to advanced world standards in the same products. 2Principle of operationThe WJQ5 6J-10 shear pump adopts a set of mechanical seal for no leakage at stuffing box. Inside pump is a 300 series stainl

24、ess steel turbine containing 44 nozzles, four scoops and shear 18plate. Fifty percent of the fluid is sheared twice each time through the pump. This turbine shear pump is mounted on a special base with belts and sheaves to drive pump, OSHA type belt guard and a 75HP/102(55kw/75kw) 1480 RPM EXPLOSION

25、 PROOF U/L approved electric motor, 460 volts, 3 phase 60 cycle. Included is a special hopper(ZHP150) with nozzle sized for this application and one mud kit as a package in order to build a complete shear and hydration system. The pump is designed to give longer service life through the improved sha

27、r improved WJQ56J-10 turbine shear pump performance in both oilfield and industrial applications.Warning! This pump can not be used on active mud system since it will shear drill solids and barite. These solids will also damage pump very quickly.The principle sees figure 1.19Figure 1 Principle diagr

28、am of WJQ56J-10 shear pumpFluid enters at “V” and is pumped parallel to the shear “P”. The chambers scoops 50% of the volume being pumped and jets that fluid through 44 nozzles “N” and impacts the shear plate “P” at very high velocity at “M” 90 degrees to the fluid entering the pump. The total fluid

29、 “V” and “N” travels down the shear plate to “T” where the fluid is further sheared due to the shape and speed of the plate tip.3Explanation of modelWJQ 5 6 J-10Turbine nominal dia.(Inches)Seal formPump inlet dia.(Inches)Pump outlet dia.(Inches)Turbine shear pump4Performance Table(Table 1)Power(kw)M

The capacity of a centrifugal pump should never be adjusted by throttling the suction line, but a positive shut-off valve of a type to cause minimal turbulence should be installed in the suction line to permit the closing of the line for removal of the pump for inspection 26and maintenanc

42、e.C. The suction line should be designed to eliminate any air pockets. The pipes should gradually slope downwards to the supply source to eliminate air pockets. Please use a vacuum pump or foot valve for priming if you operate the pump the pump under the condition of suction lift.DThe suction line s
