英國GRIMM格林進口單螺桿泵概述：
          進口單螺桿泵是按迥轉嚙合容積式原理工作的新型泵種，主要工作部件是偏心螺桿(轉子)和固定的襯套(定子)。
          由于該二部件的特殊幾何形狀，分別開成單獨的密封容腔，介質由軸向均勻推行流動，內部流速低，容積保持不變，壓力穩定，因面不會產生渦流和攪動。每級泵的輸出壓力為0.6MPa，揚程60m(清水)，自吸高度一般在6m，適用于輸送介質溫度80℃以下(特殊要求可達150℃)。
          因定子選用多種彈性材料制成，所以這種泵對高粘度流體的輸送和含有硬質懸浮顆粒介質或含有纖維介質的輸送，有一般泵種所以能勝任的特性，其流量與轉速成正比。
          傳動可采用聯軸器直接傳動，或采用調速電機，三角帶，變速箱等裝置變速。這種泵零件少，結構緊湊，體積小，維修簡便，轉子和定子是本泵的易損件，結構簡單，便于裝拆。

英國GRIMM格林進口單螺桿泵工作原理及特性：

            進口單螺桿泵的工作原理是單線螺旋的轉子在雙線螺旋的定子孔內繞定子軸線作行星回轉時，轉子——定子副之間形成的密閉腔就連續的、勻速的、容積不變的將介質從吸入端輸送到壓出端。由于這巧妙的工作原理，使單螺桿泵具有一般性泵的通用性能外。其zui顯著的特點：
1、可輸送高粘度的介質。根據泵的大小不同，介質的zui高粘度為37000厘泊-200000厘泊。
2、可輸送含固體顆粒、磨削顆粒和纖維的介質。其含量一般可高達介質的40%，當介質中所含固體為粉末狀細微顆粒時，zui高可達70%，根據泵的大小不同允許介質中所含固體顆粒粒徑zui大為2毫米——40毫米。
3、輸出的液體連續均勻、壓力穩定、攪動小，對敏感性的液體不會發生成分的改變。 
4、流量與轉速之間為簡單的正比關系。可通過調節轉速進行流量的調節，配上變速的電動機，可成為變量泵。
5、壓力能隨輸出管道阻力自動調節。在0-36(公斤/厘米2)壓力之間，用戶很容易調到所需的壓力。這樣既節能，又避免壓力太高或太低而影響工藝流程。
6、結構簡單、磨損少、維修方便。
與其它類型泵相比：
和離心泵相比，單螺桿泵不需要裝閥門，而流量是穩定的線性流動。
和柱塞泵相比，單螺桿泵具有更好的自吸能力，吸上高度可達8.5米水柱。
和隔膜泵相比，單螺桿泵可輸送各種混合雜質，含有氣體及固體顆粒或纖維的介質，也可輸送各種腐蝕性物質。
和齒輪泵相比，單螺桿泵可輸送高粘度的物質。
與柱塞泵、隔膜泵及齒輪泵不同的是，單螺桿泵可用于藥劑填充和計量。

UK GRIMM imported single screw pump summary:

           The import of single screw pump is a new type of pump to mesh volume by circumventing the work principle, the main working parts are eccentric screw (rotor) and fixed lining (stator).

Due to the special geometry of the two parts, respectively, into a separate sealing cavity, medium introduced by the uniform axial flow, internal flow rate is low, the volume remained unchanged, the stable pressure, because the surface does not produce eddy current and stirring. The output pressure of each stage pump is 0.6MPa, the head 60m (clean water), the self-priming height is generally at 6m, suitable for conveying medium temperature below 80 degrees (special requirements up to 150 degrees Celsius).

        Because of the stator made of various elastic material, so the pump for high viscosity fluid and suspended particles containing medium or hard with fiber transmission medium, a general pump can do so, the flow rate is proportional to the speed.

        Transmission can be driven directly by coupling, or by speed control motor, V-belt, transmission and other devices. The pump has the advantages of few parts, compact structure, small size, easy maintenance, and the rotor and the stator are the wearing parts of the pump. The utility model has the advantages of simple structure and easy assembly and disassembly.

UK GRIMM imported single screw pump operating principle and characteristics:

The working principle of single screw pump imported is single rotor in the stator screw hole in the bifilar helix around the stator axis for planetary rotation, the rotor and stator side sealed cavity formed between the constant volume of continuous, uniform, medium from the suction side to the extrusion end conveyor. Because of this ingenious working principle, the single screw pump has the general performance of the general pump. Its most striking features:

1.Can transport high viscosity medium. According to the pumps of different sizes, the highest viscosity medium for 37000 centipoise CPS -200000.

2.Conveying medium containing solid particles, grinding particles and fibers. The general content of the medium can be as high as 40%, when the medium contained in the solid fine powder particles, up to 70%, according to the pumps of different sizes to allow medium containing solid particles to a maximum of 2 mm - 40 mm.

3.The output of liquid continuous uniform, stable pressure, stirring little, the sensitive liquid will not change the composition.

4.Flow and speed is a simple direct relationship. By adjusting the speed of flow adjustment, coupled with the variable speed motor, variable pump can be.

5.The pressure can be adjusted automatically with the resistance of the output pipe. At 0-36 (kg/cm, 2) pressure, the user is easily transferred to the required pressure. This will save energy and avoid too high or too low pressure to affect the process.

6.Simple structure, less wear and easy maintenance.

Compared with other types of pumps:

Compared with centrifugal pumps, the single screw pump does not need to install the valve, and the flow is a steady linear flow.

Compared with the plunger pump, single screw pump has better self-priming capacity, suction height of up to 8.5 meters water column.

Compared with diaphragm pumps, single screw pump can transport a variety of mixed impurities, containing gas and solid particles or fiber medium, can also transport a variety of corrosive substances.

Compared with gear pumps, single screw pumps deliver high viscosity materials.

Unlike piston pumps, diaphragm pumps, and gear pumps, single screw pumps can be used for pharmaceutical filling and metering.
