JMQB5×6-10剪切泵專門用于剪切鉆井液的聚合物和粘土。鉆井液系統中的聚合物(或粘土)應提前充分地剪切改善性能后再進入鉆井液系統，其效果才能充分發揮。如聚合物(或粘土)沒被充分剪切，在次循環中振動篩網就可能被堵塞，從而損失大量聚合物，鉆井液中的大尺寸的固相顆粒難以除掉，鉆井成本增加;同時，在鉆井液中，如聚合物(或粘土)沒被充分剪切，鉆井液會產生許多“魚眼”，從而傷害地層，使地層滲透率降低，油氣層減產。實際使用證明，JMQB5×6-10剪切泵具有優良的性能，它能為高分子聚合物(或粘土)迅速水合提供高度的剪切，解決聚合物(或粘土)在鉆井液中因水合不好而存在的突出問題。同時，JMQB5×6-10剪切泵能使聚合物用量減少15%以上，膨潤土用量減少30%以上，并且能減少泥餅和液流損失，降低鉆井液剪切比速率，提高凝膠強度，從而達到了國外同類產品的水平。另外，通過設計改進，其軸封結構更可靠，使用維護也更方便。
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.
■ 型號說明Explanation of model
■ 原理 Principle of Operation
●JMQB5×6-10剪切泵密封采用了非常可靠的復合密封，保證無泄漏。泵內部配有一個300mm不銹鋼渦輪及一個剪切板，渦輪上有導葉、主葉輪、44個噴嘴、4個收集室，能夠產生超過25.4m/s的小端剪切(液體剪切)。當液流通過剪切泵時，有一半(50%)的液體在渦輪收集室的強力推進下將被剪切兩次。本泵安裝在一專用底座上，并用皮帶輪、窄V帶和55KW防爆電機驅動;與泵配套使用的還有一個尺寸適合的混合漏斗，與泵組成一個完善的剪切及水合作用系統。由于該泵軸封的改進，其使用壽命大大提高。
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.
●如遵循該泵安裝及特殊條件應用的規則，將進一步提高其性能。
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.
●本公司將對在油田及工業應用中有利于提高該泵性能的一般及特殊建議進行處理。
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：該泵不能用于活性泥漿系統，因為其中的鉆井固體及重晶石，它們在受到剪切時將很快損壞該泵。
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.
