YB1 vane pump appearance and three-dimensional decomposition diagram
(1) Prepare a set of hexagon wrench, an oil-resistant rubber plate, an oil pan and other appliances.
(2) Screw off the 4 screws 23, remove the pump cover 7. china hydraulic valve manifold manufacturers
(3) Unload pump shaft 3.
(4) Remove the components composed of left oil pan 13, right oil pan 18, stator 16, rotor 14, etc., so that they are separated from the pump body 22.
(5) Remove the sealing ring 8, 9, 10, 21, etc. china hydraulic valve manifold manufacturers
(6) Then disassemble the left and right oil pan, stator, rotor and other components.
① Remove the screw. 19.
② Remove the left oil pan 13, the right oil pan 18, and the positioning pin 17.
③ Remove the stator 16 and the rotor blade 15. china hydraulic valve manifold manufacturers
(7) Observe the role and structure of the main parts of the vane pump.
(1) Observe the composition of four arcs and four transition curves on the inner surface of the stator.
(2) Observe the inclination Angle and inclination direction of the blade groove on the rotor blade.
③ Observe the structure of the oil tray. china hydraulic valve manifold manufacturers
(4) Observe the oil suction port, oil pressure port, triangular groove, annular groove and groove bottom hole, and analyze its role.
⑤ Observe the position and form of the sealing ring used in the pump.
(8) According to the reverse sequence of the disassembly of the blade pump. Before assembly, clean all parts, apply lubricating fluid to the mating surface, pay attention to the assembly of seals, and check whether the rotary direction of the pump shaft is consistent with the suction oil port of the pump.
(9) Clean up the site after the assembly is completed. china hydraulic valve manifold manufacturers
