英國GRIMM格林進(jìn)口雙螺桿泵 UK GRIMMImported twin screw pump

英國GRIMM格林進(jìn)口雙螺桿泵概述： 進(jìn)口雙螺桿泵在工作過程中，螺桿與螺桿兩個(gè)以及螺桿與襯孔之間形成密封腔，液體經(jīng)進(jìn)口進(jìn)入泵內(nèi)，然后進(jìn)入密封腔，隨著螺桿的回轉(zhuǎn)運(yùn)動，由進(jìn)口處平穩(wěn)的被輸送到出口處。襯孔的相對位置由止口定位，螺桿軸由軸承支承定位，而工作期間保持螺桿和螺桿之間、以及螺桿與襯孔之間互不接觸。因而，泵允許短時(shí)間干運(yùn)轉(zhuǎn)；并允許輸送各種液體介質(zhì)（如非牛頓液體、潤滑性液體、非潤滑性液體等）。因進(jìn)口流道的特殊設(shè)計(jì)以及工作時(shí)液體的軸向速度相對較小，因此泵的NPSHr值佷小，有很好的自吸能力。軸承和同步齒輪由齒輪箱中的齒輪油潤滑。

可方便的拆下泵體聯(lián)接螺釘，從而直接清洗泵體、螺旋套及機(jī)械密封，過流部分無死角。可用溫度低于180℃的蒸汽或其他介質(zhì)對泵進(jìn)行清洗或消毒。泵的出口科可自行安裝安全措施（如溢流閥、壓力控制閥、安全閥等）。如需要，泵機(jī)組可提供為移動式（底座由四個(gè)小輪和牽引扶手）。

英國GRIMM格林進(jìn)口雙螺桿泵特點(diǎn)：

1、結(jié)構(gòu)先進(jìn)，性能優(yōu)越：改變傳統(tǒng)高壓平衡技術(shù)，采用主、從桿的軸向力低壓平衡裝置，受力平衡均勻，螺桿不變形，運(yùn)行可靠穩(wěn)定，無脈動，噪音低；
2、獨(dú)特設(shè)計(jì)，密封可靠：泵采用機(jī)械密封形式，密封腔壓力與吸入壓力相通，同時(shí)結(jié)構(gòu)設(shè)計(jì)上對密封充分冷卻循環(huán)，保證密封效果，無泄漏；
3、優(yōu)化改進(jìn)，外形美觀：改變傳統(tǒng)的進(jìn)、出口的位置，使得進(jìn)出口分布在泵兩側(cè)并成一條直線，外形美觀，同時(shí)在設(shè)計(jì)上進(jìn)行創(chuàng)新，在用戶現(xiàn)場不用改變管線就可實(shí)現(xiàn)進(jìn)出口的互換；
4、泵芯組件，方便維修和配件更換：泵結(jié)構(gòu)簡單緊湊，泵芯總成采用組件式結(jié)構(gòu)，可整體取出，便于維護(hù)、修理；
5、安全閥組件，保護(hù)產(chǎn)品安全：產(chǎn)品所配安全閥可以瞬間保護(hù)泵，防過載，但不能作為管道的溢流閥使用；
6、進(jìn)出口多種組合形式，方便現(xiàn)場管道連接；
7、多種安裝方式，更好滿足工況安裝要求。

UK GRIMMImported twin screw pumpsummary:

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 GRIMMImported 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.
