Quantitative axial piston pump is a kind of axial piston pump, which is widely used in various industries. It can be said that as long as the axial piston pump is used, we will know how to use it. However, many technical aspects or definitions may not be clear to many people. Today, axial piston pump manufacturers have to tell Everyone’s amazing theory is about the classification of the action value of a quantitative axial piston pump. The action value of the quantitative axial piston pump can be divided into the pull-in voltage and the release voltage; the pull-in voltage refers to the minimum voltage when the electric lubrication pump can be sucked in by slowly increasing the voltage at both ends of the suction table coil before the electric lubricating pump is sucked in. Release voltage refers to the maximum voltage at which the electric lubrication pump is released after the electric lubrication pump is sucked in, and the voltage of the sucking coil is slowly reduced. Generally, the pull-in voltage is not less than 85% of the rated voltage of the coil, and the release voltage is not more than 70% of the rated voltage of the coil.
