Main parameters of A2FM180/61W-VAB100 motor: Working pressure and rated pressure Working pressure: The actual pressure of the input plunger pump oil. Its size depends on the load on the plunger pump. The difference between the inlet pressure and outlet pressure of a plunger pump is called the pressure difference of the plunger pump. Rated pressure: According to the test standard, the pressure at which the plunger pump can continue to operate normally. Displacement and torque Displacement: The amount of liquid that a hydraulic plunger pump must input per revolution, regardless of leakage. Actual torque T: The loss torque caused by the actual mechanical loss of the plunger pump Δ T is less than the theoretical torque Tt. It is equivalent to mechanical efficiency η Mm: The actual ratio of the plunger pump. Convert the output torque of the plunger pump into the theoretical output torque.
