FAQ
Q: What is the delivery date after an order is placed?
Q: If the products do not meet the requirements, how to solve the problem?
Q: How to calculate torque?
Torque (Nm) = Displacement (cc/rev) x Working Pressure (MPa) x 0.16 (Factor)
According to the functional theorem: Vm (ml per radian) × w (radian per second) × p (MPa, differential pressure) × (total hydraulic motor efficiency) = w (radian per second) × T (Nm); so T =Vm×P×η; where the milliliter per radian of Vm is converted into milliliter per revolution and needs to be divided by 2π, which is multiplied by 0.16.
The displacement can be seen from the product label. The working pressure depends on the pressure gauge at the entrance of the orbit hydraulic motor. Knowing these two values, you can calculate the output torque of the orbit hydraulic motor at this time.
