The Used For Hydraulic Cylinder

The hydraulic cylinder generally refers to the hydraulic cylinder. The hydraulic cylinder is a kind of hydraulic actuator which transforms the hydraulic energy into mechanical energy and makes a linear compound movement (or swing motion). It is simple in structure and reliable in operation. When it is used to realize reciprocating motion, it can avoid decelerating device, and has no transmission clearance, so it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is directly proportional to the effective area of the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer and exhaust devices depend on the specific application, other devices are essential.

Generally, it is composed of cylinder block, cylinder rod (piston rod) and seals. The inside of cylinder block is divided into two parts by piston, and each part has an oil hole. Because the compression ratio of the liquid is very small, when one of the oil holes enters oil, the piston will be pushed to make the other oil hole come out, and the piston drives the piston rod to extend (retract) movement, otherwise, it still works. The working principle of the hydraulic cylinder, first of all, its five basic components: 1-cylinder barrel and cylinder head 2-piston and piston rod 3-sealing device 4-buffer device 5-exhaust device. The working principle of each kind of cylinder is almost the same. Take a manual Jack as an example, the jack is actually the simplest oil cylinder. The hydraulic oil enters the oil cylinder through a single valve through the manual pressurization stem (hydraulic manual pump). At this time, the hydraulic oil entering the oil cylinder can’t go back again because of the single valve, forcing the cylinder rod to go up, and then continue to make the hydraulic oil continuously enter the hydraulic cylinder during the process of working, so that it will continue to rise. When you want to lower, open the hydraulic valve to make the hydraulic oil return to the oil tank.

This is the simplest The working principle of single is improved on this basis
Hydraulic cylinder is mainly used in loader, excavator, forklift, dump truck, bulldozer, lifting platform, garbage truck, agricultural tractor, etc.
