Piston Rod—An important part of the shock absorber

piston composition:
Piston components include: pistons, piston rings, support rings, piston rods, etc. According to different structural forms, pistons can be divided into cylindrical pistons (the length is larger than the diameter), disc pistons (the length is smaller than the diameter), differential pistons, combined pistons and plunger pistons.

After rolling, the reduction of surface roughness value can improve the fit properties. At the same time, the friction damage to the seal ring or the seal when the cylinder rod and piston moves is reduced, and the overall service life of the oil cylinder is improved. The rolling process is an efficient and high-quality process measure.

The role of the piston rod:
The function of the piston rod is to connect the piston and the crosshead, transmit the force acting on the piston and drive the piston to move.
Basic requirements for the piston rod:
(1) There must be sufficient strength, stiffness and stability;
(2) Good wear resistance and high machining accuracy and surface roughness requirements;
(3) Minimize the influence of stress concentration on the structure;
(4) Ensure reliable connection and prevent loosening;
(5) The design of the piston rod structure should facilitate the disassembly and assembly of the piston.
Piston rod overheating
(1) When the piston rod and the stuffing box are assembled, there is a deflection, which causes local mutual friction, and should be adjusted in time;
(2) The holding spring of the sealing ring is too tight and the friction force is large, so it should be adjusted appropriately;
(3) The axial clearance of the sealing ring is too small, and the axial clearance should be adjusted according to the specified requirements;
(4) The amount of oil supplied is insufficient, and the amount of oil should be appropriately increased;
(5) The running-in of the piston rod and the sealing ring is poor, and the running-in should be strengthened during the grinding;
(6) Impurities are mixed in gas and oil, which should be cleaned and kept clean.
