What is hydraulics like? Can you give us a few simple examples?

Hydraulic pressure. A complete hydraulic system consists of five parts, namely power elements, actuators, control elements, partsless, and hydraulic oil. The function of the power element is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, which refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system.

The structural forms of hydraulic pumps generally include gear pumps, vane pumps and piston pumps.

The role of actuators, such as hydraulic cylinders and hydraulic motors, is to convert the pressure energy of the liquid into mechanical energy to drive the load in a linear reciprocating or rotary motion. Control elements (i.e., various hydraulic valves) control and regulate the pressure, flow and direction of fluids in hydraulic systems. According to the different control functions, hydraulic valves can be divided into village force control valves, flow control valves and directional control valves.

Pressure control valves are divided into benefit flow valves (safety valves), pressure reducing valves, sequential valves, pressure relays, etc.; Flow control valves include throttle valves, adjusting valves, diverter collector valves, etc.; Directional control valves include check valves, hydraulic check valves, shuttle valves, reversing valves, etc. According to different control methods, hydraulic valves can be divided into on-off control valves, fixed-value control valves and proportional control valves. Auxiliary components include oil tank, oil filter, oil pipe and pipe joint, sealing ring, pressure gauge, oil level oil temperature gauge, etc.

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.

Jacks are used to repair cars, and hydraulic pressures are used for dump trucks.

The characteristics of hydraulic technology are suitable for the requirements of automation, high performance, large capacity, small size and light weight of various machines and equipment. Therefore, although it is a relatively new branch of technology, it is widely used in the transmission mechanism of the main power, the operating mechanism of the auxiliary machine or the operation automation control mechanism.

1. After the First World War, hydraulic control technology began to be applied to sea boats, and after the Second World War, it has been widely used in various fields of land, sea and air. Soon, the hydraulic control system, which was first developed in military products, was popularized and applied to various industrial production sectors.

2. In terms of missiles, with the exception of small air-to-air and surface-to-air missiles and close-range anti-tank missiles, many of which are controlled by air pressure because of their light weight and small guiding power, almost all medium-range and long-range missiles are controlled by hydraulic pressure.

3. In terms of ground equipment, hydraulic servo systems were used in anti-aircraft shooting 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.

4. In the civil industry, the automatic machine tools, machining centers, manipulators, robots, rolling mills, construction machinery, chemical machinery and other industrial sectors of the metallurgical industry have applied a large number of hydraulic control. Due to the increasing degree of automation in all walks of life, the running speed and power of machinery and equipment are also increasing, so hydraulic control technology is also more and more widely used.

Hydraulic motors, hydraulic pumps, torque converters, 、。。 The telescopic arm in the loader should be hydraulically driven, the jack should be hydraulically output, the hydraulic damping device in large buildings should be used to regulate the frequency, the concrete mixer should be hydraulic, the drilling pump should be driven by a hydraulic pump, the wharf crane crane should be hydraulically driven by the rotary arm, the stamping and forming of the machinery manufacturing industry should be hydraulic, the hydraulic platform in the CNC machine tool, and the shearing machine, the bending machine, and so on require hydraulic force.

In fact, there are various hydraulic pumps or hydraulic motors on various aircraft, ships, and construction machinery, which is the most common place for hydraulic applications.

[Physics] [Pascal's Law and Applications] - Principles and Applications of Hydraulic Transmission.

It is used for warehousing and handling, transportation lines, automated warehouses, wood processing, medical operating tables, decoration high-altitude maintenance, aerial work, lifting stages, etc.

Construction machinery is basically the application of hydraulics.

To put it simply, it is a system that uses a pump to convert the mechanical energy of the motor into hydraulic energy to realize the work of the drive actuator.

A system that conducts pressure through a liquid carrier.

The hydraulic pump provides power to the hydraulic oil to propel the hydraulic actuator to work.

Within the set system pressure, the pressure of the hydraulic oil is determined by the load, for example, if the load of the cylinder is very low, as long as the hydraulic pressure is very small, the cylinder can be lost to work.

If the load is too large and the pressure exceeds the system setting pressure to push the actuator to work, the system safety valve is relieved.

If there is an electric motor to pressurize the liquid, pay careful attention to the hydraulic station and the hydraulic equipment have an electric motor, and the small hydraulic equipment manpower pressurizes the liquid, such as the hydraulic jack for repairing the car.

The system pressure is determined by the load and has nothing to do with anything else.

In a closed environment, the force exerted by the liquid on the surroundings is the pressure.
