Installation of axial piston pumps
(1) Before installation, all parts or components to be installed should be checked again and recorded.
(2) Remove burrs in various parts, especially the sharp corners.
(3) Each part should be carefully cleaned before installation, and beware of impurities, dust, dirt, etc. mixed into the appearance of the cooperation room in the pump to avoid scratching the smooth appearance of each cooperation piece.
(4) When installing, force do not hit, when it is necessary to hit, you cannot directly hit the parts with a hammer, and you must pass through the center object (such as a copper rod) pad.
(5) When installing, beware of the steel ball of the centering spring, you can first change the steel ball to clean the butter, so that the steel ball sticks to the inner sleeve of the spring or the return disk, and then install. Otherwise, if the steel ball falls into the pump during installation, other parts in the pump will be damaged during work, so that the pump can no longer be repaired, which must be noted.
Pump distribution surface part diagram (6) There is a positioning pin on the joint table between the pump body and the distribution plate, and it should not be pulled out under normal circumstances. If the end face of the regrinding distribution plate is pulled out, attention should be paid to the accurate orientation of the positioning pin to the pin hole on the pump body when reinstalling, and the oil absorption cannot be normal if the installation is wrong. As shown in Figure X, if the hydraulic pump works normally (press A direction), the locating pin needs to be installed in hole 1; If the hydraulic pump works in reverse (in the B direction), it is necessary to install the locating pin in hole 2; If the hydraulic pump needs to be used as a hydraulic motor, the positioning pin must be installed in hole 3 regardless of forward rotation or swing.
(7) After the variable head is installed, it should be adjusted freely within 0 ° ~ 21 °, and the oblique angle of the Z final adjustment variable head should be 20 ° 30 ́, and a layer of clean mechanical oil should be applied to the surface with the surface roughness that meets the requirements.
(8) When tightening the screws, it should be interspersed with symmetrical and uniform force, tightened in stages, and rolled the pump shaft by hand on one side to ensure that the rolling is sensitive and stable, and there is no barrier scene of light and heavy differences.
