When the dirt is gradually accumulated, it is possible to have
the stick condition between the plunger and bearings. It must have
communication holes near bearings. In this case, this fluid
communication path is 1 -> 2 -> stop. The fluid cannot flow from
2 to 3 resulting in the oil temperature rising and lack of enough
convection. Also insufficient thickness of the upper stator
results in no communication holes in the upper stator. | |
The upper stator uses three parts and cost higher than the target price. | |
The lower stator uses three parts and cost higher than the target price. |
First of all, SINS uses a special bearing with
twin-communication grooves to communicate the fluid path: 1-> 2
-> 3 -> circulation. In addition, the original part-2 are all
canceled. The special bearings were setup in the stators directly. Of
course, the magnetic performance needs to consider first. When the
magnetic performance is the same as original, SINS' design adds on the
feature - lower and stable oil temperature and can accommodate much
more dirt than the original. | |
Only use two parts to result in the better performance. | |
