Xu Xiaofeng, Sun Zhaobo. 2003. Dynamic study on influence of gravity wave induced by unbalancedflow on Meiyu front heavy rain [J]. Acta Meteor Sinica, 61 (6) : 655-664.
When the load is serious unbalanced, each sub-channel still keeps high volumetric efficiency and equal flow.
在各油缸支路出现严重负载不平衡时，仍保持高容积效率和相同流量。

The common gear pump has such merits as simple structure, low cost, insensitive oil pollution, etc. but it has such demerits as high flow pulsation, unbalanced radial force, strong noise, etc.
