        Introduction of important components of four column hydraulic press

        Four column hydraulic press refers to the power and transmission mode of the elevator in the process of lifting. Of course, hydraulic transmission is inseparable from the most important hydraulic cylinder.
        Hydraulic system is an important part of four column hydraulic press. Hydraulic cylinder is an actuator used in hydraulic system. It is usually composed of drive body, cylinder rod and seal. The inside of the cylinder is divided into two parts by the piston, each part passing through the oil hole. Because the compression ratio of the wavy body is very small, when one oil hole enters the oil, the piston is pushed and pressed, and the other oil hole is made of oil. The piston drives the piston rod to extend.
        The hydraulic cylinder used in hydraulic lift of four column hydraulic press usually has five parts: piston and piston rod, barrel driving, cover driving, buffer, sealing device and exhaust port.
        The working principle of the four column hydraulic press is basically the same as that of the ordinary hydraulic cylinder. Take the manual Jack as an example, the jack is actually the simplest hydraulic cylinder. At this time, the hydraulic oil flowing into the four column hydraulic cylinder through the one-way valve through the manual pressure lever is a single valve, so the hydraulic oil flowing into the four column hydraulic cylinder can not be retracted again and the cylinder rod is pushed upward to keep the hydraulic oil constant. When entering the hydraulic siphon, it will continue to rise. When descending, open the hydraulic valve to return the fluctuating pressure oil of the four column hydraulic press to the oil tank. This is a simple principle of operation. Others have been improved based on this, and the principle of the cylinder is basically the same.
        Four column hydraulic press first need to understand the hydraulic oil, the bubbling in the oil is not a problem of deterioration, but caused by the oil tank in the stumbling effect. When these bubbles are brought into the hydraulic system, the hydraulic press will break down. The air bubbles should be isolated as far as possible to prevent the bubbles from entering the system.
