G型系列单螺杆泵产品简介Brief Introduction of G Single-Screw Pumps

概述Overview

G型单螺杆泵是一种内啮合的密闭式螺杆泵，属转子式容积泵，由于这种对介质的适应性强，流动平稳，吸入性能好，压力脉动小，除可以输送各种可流动的介质外，还可以输送高粘稠介质、含有硬质悬浮颗粒或固体颗粒的介质、含有纤维的介质，调节性能好，范围宽，效率高，因此，在环境保护、船舶、石油、医药、日化、食品、酿造、建筑、采矿、化学、印刷、造纸、电厂、锅炉等各种行业得到广泛应用。

G Single-Screw Pumps is an enclosed screw pump with inner gearing, a kind of rotor positive-displacement pump. As this kind of pump is characterized by being adaptable for the medium, stable flow, good suction performance and small pressure pulsation, it can transfer very viscous media or those containing hard suspended or solid grains or fiber apart from various flowing media. Besides, it boasts good adjusting performance, wide range and high efficiency. Therefore it is widely applied in various industries like environmental protection, shipping, petroleum, pharmacy, household chemical, food, brewage, construction, mining, chemistry, printing, paper making, power plants and boilers.

工作原理Working principle

单螺杆泵是一种内啮合回转式容积泵，主要工作部件是偏心螺杆（转子）和固定的衬套（定子），由于转、定子的特殊几何形状，分别形成数个单独的密封容腔，转子的运转，将各个密封腔内的介质连续地、匀速地、容积不变地从吸入端输送到压出端。由于有这些特性，单螺杆泵特别适合下列工况的工作：

The single-screw pump is a kind of rotary positive-displacement pump with inner gearing. Its main working parts include eccentric screw (rotor) and fixed bush (stator).Due to special geometric shapes of the rotor and the stator, several separate seal cavities come into being respectively. The rotation of the rotor drives the transfer of media in all seal cavities from the suction end to the extrusion end continuously at a constant speed with the same volume. By right of these characteristics, the single-screw pump is especially suitable for the following working conditions:

1、输送高粘度的介质；

   Transfer of very viscous media;

2、输送含有固体颗粒或纤维的介质；

 Transfer of media containing solid grains or fiber;

3、要求连续、压力稳定、不出现周期性压力波动；

   Requiring continuous operation, stable pressure and no regular pressure fluctuation;

4、要求搅动小、不破坏被输送介质的固有结构；

 Requiring small agitation and no damages to the inherent structure of transferred media;

5、低的噪音。

   Low noise.

应用范围

单螺杆泵作为一种通用泵，流量可以根据要求，通过改变速度进行调节，运行速度可高可低，出口压力可随泵的级数增加而增加，每增加一级，压力增加0。6MPA，在以下范围和行业广泛应用：

As a kind of universal pump, the flow of the single-screw pump can be adjusted by changing the running speed and its outlet pressure can increase along with the rise of pump stage with 0.6Mpa up per stage. It is widely applied in the following scope and industries:
