Introduction to steel casting hydraulic cylinder
Steel casting hydraulic cylinder:
The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and makes linear reciprocating motion (or swing motion). It is simple in structure and reliable in operation. When it is used to realize reciprocating motion, the reducer can be avoided, there is no transmission clearance, and the motion is stable, so it is widely used in various mechanical hydraulic systems. Output force of the hydraulic cylinder is proportional to effective area of the piston and 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. The buffer device and exhaust device depend on the specific application, and other devices are indispensable.
The hydraulic cylinder is the actuating element in the hydraulic transmission system. It is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the hydraulic cylinder realizes reciprocating motion. The structural types of hydraulic cylinders include piston cylinder, plunger cylinder and swing cylinder. The piston cylinder and plunger cylinder realize reciprocating linear motion, output speed and thrust, swing cylinder realizes reciprocating swing, and output angular speed (speed) and torque. In addition to single use, hydraulic cylinders can also be combined with two or more or with other mechanisms. To perform special functions. The hydraulic cylinder is simple in structure and reliable in operation, and has been widely used in the hydraulic system of machine tools.
Classification:
Hydraulic cylinders have various structural forms, and their classification methods are also various: according to the motion mode, they can be divided into linear reciprocating motion type and rotary swing type; According to the action of hydraulic pressure, it can be divided into single action type and double action type; According to the structure, it can be divided into piston type, plunger type, multi-stage telescopic sleeve type, gear rack type, etc; According to the installation form, it can be divided into pull rod, ear ring, foot, hinge shaft, etc; According to the pressure grade, it can be divided into 16Mpa, 25Mpa, 31.5Mpa, etc.
