1.2工作原理Operation

单螺杆泵是一种内啮合的密闭式螺杆泵，属转子式容积泵。主要工作部件由具有双头螺旋螺杆一转子组成。当输入轴通过方向节驱动转子绕定子作行星回转时，定子转子付就连续地啮合形成密闭腔，这些密闭腔容积不变地作匀带轴向运动，输入介质从吸入端流经定子一转子付输送至压出端。输入密闭腔内的介质流过定子而不被 搅动和破坏。因此，可以输送含有坚硬磨损性杂质及固体颗的介质和粘稠的液体。

The eccentric  pump is a screw pump sealed on the inside pearing belong to rotor displacement  pump. The  essential part consists of combination of combination of a stator with two start female thread and a rotor with  single-start screw. When the sriving-shaft causes the rotor in planetary motion by the universal coupling, between the stator and rotor, being in mesh continually, formed many spaces. As these spaves unchanged in voiume are axial moving, the medium handled is transmited to the outlet port. The liquid transmited to get not confused or disruptive, thus it is the most suitable for liffing mediums containing solid matter, abrasive particles and viscous liquids.

1.3设计特点Design

·联接轴两端采用一字稍万向节接头，其稍子和稍套是由特殊材料制成的，因而其寿命得到了秀大的改善，其结构简单容易拆卸。

·衬套两羰有包过来的橡胶使共与进、出管联接处密封可靠；从而保证了衬套体不受到腐蚀。

·在吸入管和轴承体之间装有一个可进行更换的填料箱，即能用于填料密封又能用于机械密封（可进行不同形式的密封更换）

·GS系列吸入管和压出管的联接是标准DIN1187-A的螺纹联接，可以快速拆卸吸入和压出两侧的管子和软管。

*The coupling rod terminates at both ends in pintype universal joints, The pin and bushing are made of special metal, the durability of joint is improved greatly. Simple

Construction. Easy and puick to dismantle(Fig.1)

*Stator provided at both ands with external collars vulcanized to it, which provide a safe seal to the suction and discharge section . It protect the stator casing against corrosion.

*Between the suction casing and bearing horsing is situated an interchangeable housing for a suiffing  box  or mechanical seal(pumps can be converted retrospectively  to a different type of seal )

*Gs pumps suction-,discharge-connections with threaded connections according to DIN 1187-Aasa standard . Thus, a quick disassembly of pipe and hose connections on suction and pressure side is possible.
