  • Fault and Solution of Hydraulic Jacks Cylinders -

    The hydraulic pump is a key component of the hydraulic system. After the hydraulic pump is damaged, it will have a series of effects on the system pressure and flow. The damage of the hydraulic pump mainly occurs on the working part, moving parts and power transmission parts, such as the wear of the working part, the damage of the bearing and the torsion of the transmission shaft.
