Oil film protection in GANTRY PRESS
The hydraulic overload protection equipment and its pipelines in GANTRY PRESS have high requirements, and hydraulic and smooth pipelines also require excellent sealing. Leakage at such seals must be controlled to the lowest possible limit. In the cylinder of the four-column press, which mainly transmits motion, if there is a small amount of leakage at the seal, an oil film will be formed to protect the seal.
GANTRY PRESS has accumulated a lot of money under the action of impact load, and no matter how good the sealing equipment is, it cannot be guaranteed to be leak-proof. Leakage that does not affect the performance, inevitable leakage and lubricating oil that has completed the lubricating effect can be recovered because it pollutes the environment and hinders the operation of the machine. To weaken the mechanical impact, add anti-vibration equipment to the base feet of the four-column press, plan buffer equipment at the bottom dead center of the slider and the top dead center of the air cushion, install buffers on the hydraulic press, and use energy limitation and bypass methods to design the hydraulic system. , Use the accumulator to eliminate the impact, properly increase the diameter of the pipe, and use the hose.
In addition, in the piping design, try to make the GANTRY PRESS hydraulic components converge on the oil circuit board, use the least number of pipe joints, and connect the pipelines by welding as much as possible. Ensure that the seal is firm and eliminate the radial force on the piston rod to avoid unilateral wear of the sealing ring.
