Answer:

Characteristics and basic principle of hydraulic drive 1. Introduction of hydraulic transmission Hydraulic transmission is the transmission of energy and control by using liquid as a working medium. Hydraulic and pneumatic transmission and known as the fluid drive, is proposed according to the 17th century PASCAL hydrostatic pressure transmission principle and developed a new technology, is widely used in industrial and agricultural production technology. In 1795, the British Joseph Braman applied to industry in the form of a hydraulic press, creating the world's first hydraulic press. In 1905, the working medium water was changed to oil and further improved.
Hydraulic transmission has many outstanding advantages, so its application is very broad, such as the plastic processing machinery, pressure machine, machine tool, etc. Construction machinery, construction machinery, agricultural machinery, automobiles etc. Metallurgical machinery, hoisting device and roll adjusting device for steel industry; Flood control gates and levees of civil water conservancy projects, river bed lifting devices and bridge control institutions; Power plant turbine speed regulating device and so on; Ship's deck lifting machinery, bow door, bulkhead valve and stern thruster; Control devices for special technologies, measuring buoys and elevating stages, etc. Military industrial use of artillery control, ship stabilizer, vehicle simulation, landing gear for aircraft landing gear and rudder control device
The basic principle of hydraulic transmission is that in a sealed container, the energy transfer and transfer power is achieved through the use of pressurizing fluid as a working medium. The liquid is called a working medium, which is generally used for mineral oil, which is similar to the belt, chain and gear in the mechanical drive. The hydraulic drive is the PASCAL principle! PASCAL's principle is that, in a closed environment, a force is applied to the liquid, and the liquid will deliver the force in all directions! The force is the same size! The hydraulic drive is to use this physical property to apply a force to an object, using PASCAL's principle to make this force bigger! Thus the effect of lifting heavy objects! Hydraulic transmission in the valve industry has also been a lot of applications, such as machine tool manufacturing processing equipment, valves, hydraulic valve test equipment, valves, hydraulic transmission device, etc.
Use hydraulic drive to maintain high maintenance, working oil should always be clean. (2) high precision requirements for hydraulic components, complex technology and high cost; (3) the maintenance of hydraulic components is more complex and requires higher technical level; (4) using oil as a working medium, there are fire hazards in the work area; (5) transmission is inefficient.
Small size and light weight, so the inertia force is smaller, and when suddenly overloaded or stopped, there is no big impact. (2) the ability to automatically adjust the traction speed at a given range, and to achieve the infinitely high speed adjustment; (3) it is easy to change the direction of the rotation of the work mechanism without changing the rotation of the motor. (4) the tubing connection between the hydraulic pump and the hydraulic motor is not strictly limited to each other in space. (5) because of the use of oil as the working medium, the component can lubricate the surface of the relative motion, wear little and use long life. (6) the control is simple and the degree of automation is high; It is easy to implement overload protection.
