1, domestic water and tap water are transported by water power.
2. Blood pressure of animals, including people, and the flow of blood is transmitted by hydraulic pressure.
3, body fluids from outside the cell into the cell is hydraulic transmission.
4, urination is hydraulic transmission.
Medical injection is delivered by hydraulic pressure.
Basic principles:
The hydraulic system uses the hydraulic pump to convert the mechanical energy of the prime mover into the pressure energy of the liquid, and transmits energy through the change of the pressure energy of the liquid. Through the transmission of various control valves and pipelines, the pressure energy of liquid is converted into mechanical energy by means of hydraulic actuators (hydraulic cylinders or motors), thus driving the working mechanism and realizing linear reciprocating motion and rotary motion. Liquid is called working medium, generally mineral oil, and its function is similar to that of belt, chain, gear and other transmission elements in mechanical transmission.
In hydraulic transmission, hydraulic cylinder is the simplest and relatively complete hydraulic transmission system. By analyzing its working process, we can clearly understand the basic principle of hydraulic transmission.
