Cutting machine hydraulic cylinder working principle

The working principle of the hydraulic cylinder has five main components. Let's first talk about its basic five components: cylinder and cylinder head, piston and piston rod, sealing device, buffer device, exhaust device.

The working principle of each cylinder is almost the same. In the case of a manual jack, the jack is actually a simple cylinder. Through the manual pressurized stalk (hydraulic manual pump), the hydraulic oil enters the cylinder through a one-way valve. At this time, the hydraulic oil entering the cylinder can no longer be reversed due to the single valve, forcing the cylinder rod upward, and then the work continues to make the hydraulic oil Keep entering the hydraulic cylinder.

In this way, the pressure is continuously increased. When the pressure is lowered, the hydraulic valve is opened to return the hydraulic oil to the fuel tank. This is a simple working principle, and the others are improved on the basis of this. The principle of the cylinder is basically the same as that of the cylinder.
