英国GRIMM格林进口双螺杆泵 UK GRIMM imported twin screw pump
英国GRIMM格林进口双螺杆泵概述：
进口双螺杆泵在工作过程中，螺杆与螺杆两个以及螺杆与衬孔之间形成密封腔，液体经进口进入泵内，然后进入密封腔，随着螺杆的回转运动，由进口处平稳的被输送到出口处。衬孔的相对位置由止口定位，螺杆轴由轴承支承定位，而工作期间保持螺杆和螺杆之间、以及螺杆与衬孔之间互不接触。因而，泵允许短时间干运转；并允许输送各种液体介质（如非牛顿液体、润滑性液体、非润滑性液体等）。因进口流道的特殊设计以及工作时液体的轴向速度相对较小，因此泵的NPSHr值佷小，有很好的自吸能力。轴承和同步齿轮由齿轮箱中的齿轮油润滑。
可方便的拆下泵体联接螺钉，从而直接清洗泵体、螺旋套及机械密封，过流部分无死角。可用温度低于180℃的蒸汽或其他介质对泵进行清洗或消毒。泵的出口科可自行安装安全措施（如溢流阀、压力控制阀、安全阀等）。如需要，泵机组可提供为移动式（底座由四个小轮和牵引扶手）。
英国GRIMM格林进口双螺杆泵特点：
1、结构先进，性能优越：改变传统高压平衡技术，采用主、从杆的轴向力低压平衡装置，受力平衡均匀，螺杆不变形，运行可靠稳定，无脉动，噪音低；
2、独特设计，密封可靠：泵采用机械密封形式，密封腔压力与吸入压力相通，同时结构设计上对密封充分冷却循环，保证密封效果，无泄漏；
3、优化改进，外形美观：改变传统的进、出口的位置，使得进出口分布在泵两侧并成一条直线，外形美观，同时在设计上进行创新，在用户现场不用改变管线就可实现进出口的互换；
4、泵芯组件，方便维修和配件更换：泵结构简单紧凑，泵芯总成采用组件式结构，可整体取出，便于维护、修理；
5、安全阀组件，保护产品安全：产品所配安全阀可以瞬间保护泵，防过载，但不能作为管道的溢流阀使用；
6、进出口多种组合形式，方便现场管道连接；
7、多种安装方式，更好满足工况安装要求。

UK GRIMM imported twin screw pump summary:
imported double screw pump in the work process, the seal cavity is formed between the screw and screw and two screw and liner hole, liquid through the entrance into the pump, and then into the seal cavity, with the rotary motion of the screw, the inlet steady is transported to the outlet. The relative position of the lining hole is positioned by the stopper, the screw shaft is supported by the bearing, and the contact between the screw rod and the screw rod and the screw rod and the lining hole are not contacted during the operation. As a result, the pump allows for short periods of dry running and permits the delivery of various liquid mediums (such as non Newtonian fluids, lubricating fluids, non lubricating liquids, etc.). Because of the special design and the inlet channel when the liquid axial velocity is relatively small, so the pump NPSHr value is very small, self-priming ability good. The bearing and the synchronous gear are lubricated by gear oil in the gear box.
The utility model can conveniently remove the connecting screw of the pump body, so as to directly clean the pump body, the spiral sleeve and the mechanical seal, and the overflow part has no dead angle. Pumps can be cleaned or sterilized by steam or other medium at temperatures below 180 degrees celsius. The outlet of the pump is ready to install security measures (such as overflow valve, pressure control valve, safety valve etc.). If necessary, the pump unit can be supplied as mobile (the chassis consists of four small wheels and a traction handrail).
UK GRIMM imported twin screw pump characteristic:
1.Advanced structure, superior performance: to change the traditional high voltage balancing technology, from the axial force rod pressure balance device is adopted, the main force balance, uniform screw deformation, stable and reliable operation, no pulse, low noise;
2.Unique design, sealed reliable: the pump adopts mechanical seal form, the sealing cavity pressure and suction pressure interlinked, at the same time, the structure design on the sealing full cooling cycle, ensure the sealing effect, no leakage;
3.Optimization, appearance: to change the traditional import and export position, makes the import and export distribution in the pump side and into a straight line, beautiful shape, at the same time in design innovation, without changing the pipeline can realize the exchange of import and export on site;
4.Pump core components, easy maintenance and replacement parts: pump structure is simple and compact, the pump core assembly adopts a modular structure, can be taken out, easy to maintain and repair;
5.Safety valve components, protect product safety: products with safety valve can instantly protect the pump, overload, but can not be used as overflow valve of the pipeline;
6.import and export a variety of combinations to facilitate on-site pipe connection;
7.A variety of installation methods to better meet the working conditions of installation requirements.
