(1) The coaxiality deviation between the hydraulic pump and the hydraulic motor, the motor, the prime mover and the working mechanism shall be within 0.lmm, and the inclination between the axes shall not be greater than 1. The coupling shall not be installed by knocking, and the rotation direction of pump and motor of hydraulic pump accessories and the direction of oil inlet and outlet shall not be reversed.


(2) Before the installation of hydraulic cylinder, carefully check whether its piston rod is bent. For base type or flange type hydraulic cylinder, the method of setting block in front of the base or flange is adopted. The mounting screw shall not bear the load directly, so as to reduce the overturning moment. For pin type or earring type hydraulic cylinder, the direction of the connecting head at the top of the piston rod shall be the same as that of the trunnion, so as to ensure the stability of the piston rod. For hydraulic cylinders with long stroke and high oil temperature, one end should remain floating to compensate for the effect of thermal expansion.

(3) The direction valve of the hydraulic control valve (taking plate valve as an example) shall be generally installed with the axis horizontal; the sealing ring at each oil port of the hydraulic pump accessories shall have a certain amount of compression to prevent leakage after installation; the fixed screw shall be tightened evenly (do not use a hammer to knock or a hard wrench), do not screw it out of the way, and finally make the installation plane of the components of the hydraulic system fully contact with the installation plane of the base plate or the integrated block.


(4) Hydraulic accessories shall be installed in strict accordance with the design requirements, and pay attention to tidiness and beauty. In case of meeting the design requirements, the convenience of use, maintenance and adjustment shall be considered as much as possible. For example, the pressure gauge shall be installed at the place with small vibration and easy observation of the oil distribution plate; the accumulator shall be installed at the place where the gas cylinder is easy to be used for inflation; the filter shall be installed at the place where it is easy to be disassembled and inspected as far as possible; the cooler shall pay attention to the water quality, water quantity, water temperature, freezing of cooling water, etc.
