For mechanical industrial important aspect, China gear pump development late start also exists long lack inputs problem.

对于机械工业重要方面，我国齿轮泵的发展起步较晚，同时还存在着长期缺乏投入的问题。

A new type of gear pump — balanced compound gear pump has been presented.

研究了平衡式复合齿轮泵的流量特性，给出了瞬态流量公式及流量脉动计算式。

Gear pump structure is simple, easy to repair.

齿轮泵结构简单，易维修。

The applications of polymer melt gear pump in plastics extrusion and microcellular plastics forming are introduced.

介绍了熔体齿轮泵在塑料挤出成型及微孔塑料加工中的应用。

To this end, the gear-driven motor and pump should be connected by flexible couplings, and installed on the same floor, to ensure that the coaxial, the floor installed in elastic support, can further improve the effect of isolation.

为此，齿轮泵与驱动电机应通过柔性联轴器连接，并安装在同一底板上，以保证同轴度，该底板装于弹性支承上，可进一步提高隔振效果。

The gear pump is the volume pump's one kind, by two gears, the pump body and the first top plate is composed two seal spaces, when gear-driven, the gear withdraws the side the space volume to increase since childhood, the vacuum production, inhales the liquid, the gear meshing side's space's volume is small from the big change, but pushes in the liquid in the pipeline.

齿轮泵是容积泵的一种，由两个齿轮、泵体与前后盖组成两个封闭空间，当齿轮转动时，齿轮脱开侧的空间的体积从小变大，形成真空，将液体吸入，齿轮啮合侧的空间的体积从大变小，而将液体挤入管路中去。

The working principle and main characteristics of a new kind of gear pumps are studied in this paper.
