explain the basic construction of a hydraulic machine.
Answers
Answer:
Basically a fluid pump or hydraulic pump is a device or machine having moving mechanical components which uses energy from some source, generally electrical, supplied to it in form of mechanical energy by electrical motor.
Generally pumps have rotating parts run by the electrical motors. The rotating parts of pumps can be some volume defining components which can form an enclosed envelope of volume where the fluid can captured and displaced. Other type of rotating parts can be blades mounted on discs or shafts which rotate with the driving power and transfers that to the fluid by making it move with increased velocity.
Hydraulic machines are machinery and tools that use liquid fluid power to do simple work, operated by the use of hydraulics, where a liquid is the powering medium. In heavy equipment and other types of machine, hydraulic fluid is transmitted throughout the machine to various hydraulic motors and hydraulic cylinders and becomes pressurised according to the resistance present. The fluid is controlled directly or automatically by control valves and distributed through hoses and tubes.
The popularity of hydraulic machinery is due to the very large amount of power that can be transferred through small tubes and flexible hoses, and the high power density and wide array of actuators that can make use of this power. ❤
