英国GRIMM格林进口单螺杆泵 UK GRIMM Imported single screw pump

英国GRIMM格林进口单螺杆泵概述：
          进口单螺杆泵是按迥转啮合容积式原理工作的新型泵种，主要工作部件是偏心螺杆(转子)和固定的衬套(定子)。
          由于该二部件的特殊几何形状，分别开成单独的密封容腔，介质由轴向均匀推行流动，内部流速低，容积保持不变，压力稳定，因面不会产生涡流和搅动。每级泵的输出压力为0.6MPa，扬程60m(清水)，自吸高度一般在6m，适用于输送介质温度80℃以下(特殊要求可达150℃)。
          因定子选用多种弹性材料制成，所以这种泵对高粘度流体的输送和含有硬质悬浮颗粒介质或含有纤维介质的输送，有一般泵种所以能胜任的特性，其流量与转速成正比。
          传动可采用联轴器直接传动，或采用调速电机，三角带，变速箱等装置变速。这种泵零件少，结构紧凑，体积小，维修简便，转子和定子是本泵的易损件，结构简单，便于装拆。

英国GRIMM格林进口单螺杆泵工作原理及特性：

            进口单螺杆泵的工作原理是单线螺旋的转子在双线螺旋的定子孔内绕定子轴线作行星回转时，转子——定子副之间形成的密闭腔就连续的、匀速的、容积不变的将介质从吸入端输送到压出端。由于这巧妙的工作原理，使单螺杆泵具有一般性泵的通用性能外。其zui显著的特点：
1、可输送高粘度的介质。根据泵的大小不同，介质的zui高粘度为37000厘泊-200000厘泊。
2、可输送含固体颗粒、磨削颗粒和纤维的介质。其含量一般可高达介质的40%，当介质中所含固体为粉末状细微颗粒时，zui高可达70%，根据泵的大小不同允许介质中所含固体颗粒粒径zui大为2毫米——40毫米。
3、输出的液体连续均匀、压力稳定、搅动小，对敏感性的液体不会发生成分的改变。 
4、流量与转速之间为简单的正比关系。可通过调节转速进行流量的调节，配上变速的电动机，可成为变量泵。
5、压力能随输出管道阻力自动调节。在0-36(公斤/厘米2)压力之间，用户很容易调到所需的压力。这样既节能，又避免压力太高或太低而影响工艺流程。
6、结构简单、磨损少、维修方便。
与其它类型泵相比：
和离心泵相比，单螺杆泵不需要装阀门，而流量是稳定的线性流动。
和柱塞泵相比，单螺杆泵具有更好的自吸能力，吸上高度可达8.5米水柱。
和隔膜泵相比，单螺杆泵可输送各种混合杂质，含有气体及固体颗粒或纤维的介质，也可输送各种腐蚀性物质。
和齿轮泵相比，单螺杆泵可输送高粘度的物质。
与柱塞泵、隔膜泵及齿轮泵不同的是，单螺杆泵可用于药剂填充和计量。

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.
