JMQB5×6-10剪切泵专门用于剪切钻井液的聚合物和粘土。钻井液系统中的聚合物(或粘土)应提前充分地剪切改善性能后再进入钻井液系统，其效果才能充分发挥。如聚合物(或粘土)没被充分剪切，在次循环中振动筛网就可能被堵塞，从而损失大量聚合物，钻井液中的大尺寸的固相颗粒难以除掉，钻井成本增加;同时，在钻井液中，如聚合物(或粘土)没被充分剪切，钻井液会产生许多“鱼眼”，从而伤害地层，使地层渗透率降低，油气层减产。实际使用证明，JMQB5×6-10剪切泵具有优良的性能，它能为高分子聚合物(或粘土)迅速水合提供高度的剪切，解决聚合物(或粘土)在钻井液中因水合不好而存在的突出问题。同时，JMQB5×6-10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，并且能减少泥饼和液流损失，降低钻井液剪切比速率，提高凝胶强度，从而达到了国外同类产品的水平。另外，通过设计改进，其轴封结构更可靠，使用维护也更方便。

　　The JMQB5×6-10 Shear Pump generation is uniquely design pump for shearing polymers and clays. To improve the drill fluid properties, the polymers or clays should be highly sheared before adding to the drill fluid system, If not sheered, 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 JMQB5×6-10 shear pump has proven best for applying the high shear necessary to hydrate polymers and clays and to their best properties. Using the JMQB5×6-10 Shear Pump reduces the bentonite clay needed by 33% or more and polymer needed by 15% or more. It also improves fluid loss and filter cake, builds gel strength, and low shear rate viscosity to better hold up solids. With reliable shaft seal structure and more convenient in operation and maintenance, it comes up to advanced world standards in the same products.

　　■ 原理 Principle of Operation

　　●JMQB5×6-10剪切泵密封采用了非常可靠的复合密封，保证无泄漏。泵内部配有一个300mm不锈钢涡轮及一个剪切板，涡轮上有导叶、主叶轮、44个喷嘴、4个收集室，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剪切两次。本泵安装在一专用底座上，并用皮带轮、窄V带和55KW防爆电机驱动;与泵配套使用的还有一个尺寸适合的混合漏斗，与泵组成一个完善的剪切及水合作用系统。由于该泵轴封的改进，其使用寿命大大提高。

　　The JMQB5×6-10 shear pump adopts a set of compound seal for no leakage at stuffing box. Inside pump is a 300series stainless steel turbine containing 44 nozzles, four scoops and shear plate. Fifty(50)% 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(55KW)1800RPM EXPLON PEROOF U/L approved electric motor, 460 volt, 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 principles of proper pump installation and application as well as special considerations for the pump design which, if followed, will further enhance the performance of your JMQB5×6-10 turbine shear pump.

　　●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。

　　This document will deal with both general and specific recommendations for improved JMQB5×6-10 turbine shear performance in both oilfield and industrial applications.

　　●注意：该泵不能用于活性泥浆系统，因为其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。

　　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.
