When the load efficiency test of the four-column hydraulic press, the dynamometer is installed on the piston rod, gradually increase the hydraulic P, and increase the output force, and then increase the pressure value P and the corresponding output force W value record, draw a graph according to the requirements, the load efficiency of the hydraulic cylinder of the four-column hydraulic press should be higher than 90%.

The efficiency of the hydraulic cylinder of a four-column hydraulic press is different at all stages of the movement process. When starting, the hydraulic cylinder of the four-column hydraulic press must overcome the static friction of the sealing device, so the efficiency is low, and the sealing friction is small and the efficiency is high when running at high speed. However, the start-up time of the hydraulic cylinder of a four-column hydraulic press is very short, so it can usually be ignored.
