3 precautions when installing the gear pump in the hydraulic system

1, the hydraulic pump shaft and motor drive shaft concentricity deviation of less than 0.1MM, the general use of flexible coupling, V belt does not allow direct drive shaft rotation, to prevent the pump shaft by the radial force is too large, the impact Pump normal operation; 2, the direction of rotation of the hydraulic pump and inlet and outlet ports should be installed as required; 3, various types of hydraulic pump suction height, generally less than 0.5M.
