常用的几种螺杆泵规格型号有哪些?

I-1B螺杆泵是一种单螺杆式输送泵、它的主要工作部件是偏心螺旋体的螺杆（称转子）和内表面呈双线螺旋面的螺杆衬套（称定子）。其工作原理是当电动泵轴转动时，螺杆一方面绕本身的轴线旋转，另一方面它又沿衬套内表面滚动，该型泵是单螺杆式容积回转泵，该泵利用偏心单螺旋的螺杆在双旋衬套内的转动，使浓浆液沿螺旋槽由吸入口推移至排出口，实现泵的输送功能。

What are the specifications and types of screw pumps commonly used?

I-1B screw pump is a single screw pump, its main components are eccentric screw screw (called rotor) and the inner surface of the double helical surface of the screw bushing (called stator). Its working principle is when the rotating electric pump shaft, a screw will rotate around its own axis, on the other hand it rolling along the inner surface of the Bush, this type of pump is a single screw type positive displacement rotary pumps, the rotation of the screw pump with single screw in double screw eccentric bushing, the concentrated slurry along the spiral groove from the suction passage to the discharge port, to achieve delivery pump.

G型单螺杆泵是按迥转啮合容积式原理工作的新型泵种，传动可采用联轴器直接传动，或采用低速电机三角带传到，变速箱，无级变速器等装置变速。流量0.8-150m3/h，压力0.4-1.2MPa。

G type single screw pump is a new type of pump to mesh volume by circumventing the work principle, direct drive coupling drive can be used, or the low-speed motor belt to, gearbox, CVT transmission device etc.. Flow 0.8-150m3/h, pressure 0.4-1.2MPa.

LQ3A系列不锈钢转子泵（也称罗茨泵），系引进国外技术，经消化吸收，精心设计，研制而成，因为它不仅具备转子泵（例：齿轮泵、凸轮泵、螺杆泵……〕的共性，更有它独具的输送高粘度物料的特性，所以，我们又把这种泵称为胶体输送泵。
LQ3A series stainless steel rotor pump (also known as the roots pump), is the introduction of foreign advanced technology, through digestion and absorption, carefully designed, developed, in the current domestic similar products in a leading position, not only because it has all the rotor pump (for example: gear pump, cam pump, screw pump...... The common character of this system is that it has the characteristics of conveying high viscosity material, so we call this kind of pump as colloid delivery pump.
