3、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
4、理WJQ5 6JC-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
5、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。原理如图一:7 TI I图一WJQ5 6JC-10剪切泵原理图聚合物流体从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）再一次被剪切。 这样就完成了聚合物（或粘土）高度剪切而迅速水合。3. 型号说明WJQ 5 6J-10涡轮名义直径(英寸)密

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 fluid system. If not sheared, th
20、e 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 necessary to hydrate polyme
21、rs and clays and to their best properties. Using the WJQ5 6J-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 solids. With reliable shaft s
22、eal structure and more convenient in operation and maintenance, it comes up to advanced world standards in the same products.2. Principle 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 stainless steel turbine containi
23、ng 44 nozzles, four scoops and shear plate. 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) 1480RPM EXPLOSION PROOF U/L approved electric
24、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 shaft seal.There are many princi

26、 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.Figure 1 Principle diagram of WJQ5 6J-10 shear pumpFlu

37、ionThe pump should be located near the liquid source so that the suction line can be short and reduce losses. The foundation should be sufficiently rigid and substantial to absorb any vibration and support the base plate at all points. The base plate should be installed in a level position.Pulley in
38、stallationA. The axes of two pulleys must be parallel to each other and the end surface error can not exceed 2mm.B. The belts should be aligned and tightened.C. The electric motor must be mounted stably. Connection of suction pipesA. The suction line should be equal to or larger than the pump suctio
39、n.B. 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 and maintenance.C. The
40、 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.D. The suction line should
41、have a straight section into the pump of a length equivalent to at least two times its diameter.E. For temporary hook-up when flexible hose is used, a non-collapsing hose is essential since the suction line pressure is often below atmospheric pressure. A collapsed suction line will result in below a
42、verage or complete loss of flow.Discharge pipesA. A positive shut-off valve should be located in the discharge pipe to permit the closing the line for removal of the pump for inspection and maintenance.B . All pipes(including suction pipes) should be independently supported and accurately aligned. T
43、he pump must not support the weight of pipe or compensate for misalignment.C. If operating conditions are not known with sufficient accuracy, it will be necessary to provide a throttle valve in the discharge line to ensure that the pump operates at the design point.D. If the pump is connected to a pressurized system, it is important to install a check valve between
