The hydraulic system consists of hydraulic fluid, oil tank, hydraulic pump, hydraulic cylinder (motor), control valve, pipeline, etc. The hydraulic pump is the component that transmits energy in the hydraulic system, and the hydraulic cylinder and hydraulic motor convert hydraulic energy into mechanical energy. element.
1. Hydraulic pump
Hydraulic pump is the power component in the hydraulic system, which usually consists of gear pump, gear pump, plunger pump, screw pump, etc. Hydraulic pumps convert mechanical energy into hydraulic energy and compress and deliver hydraulic oil to hydraulic cylinders or other hydraulic components to drive action.
2. Hydraulic cylinder
Hydraulic cylinder, also known as oil cylinder, is a component that converts hydraulic energy into mechanical energy. The hydraulic cylinder is composed of a cylinder barrel, a piston, a piston rod, an oil port, an oil drain port, and sealing components. It controls the inflow and outflow of hydraulic oil to drive the forward and backward movement of the piston and piston rod, thereby realizing the movement of mechanical equipment.
Application scenarios: Hydraulic cylinders are widely used in industry, construction, agriculture, metallurgy, shipbuilding and other fields, such as milling machines, drilling machines, planers, presses, cranes, bulldozers, excavators, mining machinery, etc.
3. Hydraulic motor
A hydraulic motor is a component that converts hydraulic energy into mechanical energy. Its working principle is similar to that of a hydraulic cylinder. A hydraulic motor consists of the motor itself, a transmission wheel, a shaft, an oil pipe, and a sealing element. The hydraulic motor drives the motor to rotate through oil, thereby realizing the rotation of the mechanical equipment.
Application scenarios: Hydraulic motors are widely used in railways, highways, public utilities, agriculture, ships, petroleum, metallurgy, coal mines and other fields, such as rotary drilling rigs, tow trucks, muck trucks, tractors, diesel engines, cement mixer trucks, etc.
This article introduces the working principles, application scenarios and differences of hydraulic pumps, hydraulic cylinders and hydraulic motors. Hydraulic technology is widely used in industrial production. Its energy saving, high efficiency, safety, reliability and other characteristics provide strong support for the progress of the machinery manufacturing industry.
