Hydraulic pump installation should first be based on the category of hydraulic pumps and technical parameters to determine whether the vertical installation or horizontal installation or side installation.
Such as piston pumps and screw pumps can only be installed horizontally, small-displacement pumps can be placed in the tank cover horizontal installation, but it should be noted that the pump suction port to the lowest surface of the oil in the tank distance can not be greater than 500mm.
Pumps with larger displacement can only be installed using side-mounted.
Other pumps such as gear pumps, small and medium displacement can be used in horizontal installation, horizontal installation of compact structure, easy to install, high suction efficiency, there is no sucking phenomenon, try to use.
Large displacement is recommended to use horizontal or side installation. Small and medium displacement oil pumps, whether vertical or horizontal, are directly coupled with the bell housing positioning, with the concentricity of the bell housing at both ends of the stop to ensure the concentricity of the oil pump motor.
Large-displacement piston pumps can not be directly coupled with the bell jar, but the pump frame, it is necessary to adjust the level to ensure that the oil pump motor shaft coaxiality.
Horizontal installation are required for the installation of pads.
Horizontal installation is most likely to be ignored is that the suction pipe sealing is not tight, which leads to the inhalation of air, which is difficult to find, need to pay special attention.
