What equipment is the hydraulic control system mainly used in?

1. In terms of missiles, except for small air-to-air and surface-to-air missiles and short-range anti-tank missiles.

Due to their light weight and small guiding power, many of them use air pressure control, and almost all medium-range and long-range missiles are controlled by hydraulics.

2. In terms of ground equipment, hydraulic servo systems were used on anti-aircraft aircraft as early as before World War II, and now the stabilization device of tank artillery, the steering device of heavy vehicles, and the search and tracking system of radar antennas are also controlled by hydraulics.

3. In the civil industry, the machinery manufacturing industry has automated machine tools, machining centers, and manipulators.

Hydraulic control is widely used in robots, rolling mills in the metallurgical industry, construction machinery, chemical machinery and other industrial sectors.

First world war.

Later, hydraulic control technology began to be applied to sea boats.

After World War II, it has been widely used in various fields of land, sea and air, due to the development of aerospace technology, it is particularly required to have a high-precision and high-response hydraulic servo system.

Soon, the hydraulic control system, which was first developed in military products, was popularized and applied to various industrial production sectors. Today, most aircraft are hydraulics for their control and handling systems.

Hydraulic presses, excavators, lifting tables... Very wide-ranging!

Machinery that requires movement, strength that requires strength, and good stability are all used.

A complete, functioning hydraulic system should be composed of the following five main parts: 1Powerplant:

It is a device that supplies pressure oil to the hydraulic system and converts mechanical energy into hydraulic energy. The most common is a hydraulic pump. 2.

Actuator: It is a device that converts hydraulic energy into mechanical energy. Its form has a hydraulic cylinder for linear motion, and a hydraulic motor for rotary motion, and they are also called the actuators of the hydraulic system.

3.Control and regulation device: It is a device that controls or regulates the pressure, flow rate or flow direction in the system.

Such as relief valves, throttle valves, reversing valves, globe valves, etc. 4.Auxiliary devices:

Such as oil tanks, oil filters, oil pipes, etc. They are essential to keep the system working properly. 5.

Working medium: The fluid that transmits energy, i.e., hydraulic oil, etc. Since the end of the 18th century, when Britain made the world's first hydraulic press, hydraulic transmission technology has a history of two or three hundred years.

It was not until the 30s of the 20th century that it was more commonly used in cranes, machine tools and construction machinery. During the Second World War, due to the needs of the war, various military ** equipped with responsive and high-precision hydraulic control mechanisms appeared. After the end of World War II, hydraulic technology quickly shifted to civilian industry, and hydraulic technology was continuously applied to various automatic machines and automatic production lines.

Since the 60s of this century, hydraulic technology has developed rapidly with the development of atomic energy, space technology, and computer technology. Therefore, the real development of hydraulic transmission is only a matter of the last thirty or forty years. At present, hydraulic technology is developing towards rapid, high-pressure, high-power, high-efficiency, low-noise grip, durable, and highly integrated.

At the same time, computer-aided design (CAD), computer-aided testing (CAT), computer-aided control (CDC), mechatronics technology, reliability technology and other aspects of new hydraulic components and hydraulic systems are also the current development and research direction of hydraulic transmission and control technology. China's hydraulic technology was initially applied to machine tools and forging equipment, and later to tractors and construction machinery. With the introduction of some hydraulic components, production technology and self-design, China's hydraulic components have formed a series and have been widely used in various mechanical equipment.

The basic components of the hydraulic control system include three parts: power source, actuator and control mechanism.

1.Power source.

The power source of the hydraulic control system is the oil pump (or hydraulic pump), which is the working basis of the entire hydraulic control system. The basic function of the oil pump is to provide the ATF oil volume and oil pressure that meets the demand.

2.Actuator.

The actuator is mainly composed of clutch, brake cylinder, etc.

3.Control Bodies.

The control mechanism includes the valve body and various valves, including the main pressure regulating valve, the manual valve, the shift valve and the lock-up clutch control valve. The hydraulic control system also includes auxiliary devices such as accumulators and check valves to protect against shift shocks.

The hydraulic system is divided into two parts, one is the signal control part, the other is the hydraulic power part, and the signal control part is used to drive the action of the control valve in the hydraulic system. The hydraulic power part is to use a circuit diagram to show the interrelationship between different functional elements.

According to the working principle of the system, the corresponding actuator can be identified, if the actuator stretches out the corresponding element identification section is an even number, then the corresponding component identifier in the liquid combustion mountain pressure system is an odd number, through the marking number of the circuit in the hydraulic system, it is also convenient to find the system fault place in time, and it is more convenient to eliminate the system fault.

In the number of a hydraulic system, the number of a component can be divided into four parts: the device number, the circuit number, the component identifier, and the number of the component. A complete hydraulic system, in addition to power components, actuators, control components, various accessories are also indispensable for hydraulic oil.

Hydraulic oil is the working medium for transferring energy in the hydraulic system, and there are several categories such as various mineral oils, emulsions and synthetic hydraulic oils.
