Oil-slip flow measurement system analysis, aviation oil-skiing pump from the structure of the main sub-meshing swing gear pump, external meshing gradually open-line gear pump and spinner pump, installed in the transmission box, for each bearing cavity oil return, gear meshing points and bearings for oil supply lubrication cooling , the flow of the oil slide pump plays a vital role in the return capacity and the supply capacity, the flow rate is too low to cause the return oil is not smooth, the temperature of the oil mixing shell inside the box rises, the flow rate is too low to cause the oil supply capacity is not enough, the temperature of the bearing cavity of the box is raised leading to the transmission card滯 Therefore, the oil pump factory test needs to detect all levels of flow. Keywords! Air oil pump, flow, return capacity, oil supply capacity
