Do mechanical engineers make washing machines?
In most of these fields, the mechanical engineer is concerned with heat utilization or machine design–in other words, harnessing or creating energy. Machine design is more focused on hardware, including automobile engines, computers, and washing machines.
What type of engineer makes appliances?
Mechanical engineers still use basic components that have been known and used for centuries — such as wheels, axles, levers, screws, springs and hinges — to make machines such as vehicles, farm machinery, household appliances, robots and industrial equipment.
What engineer works on machines?
Mechanical engineers
Mechanical engineers design power-producing machines, such as electric generators, internal combustion engines, and steam and gas turbines, as well as power-using machines, such as refrigeration and air-conditioning systems. Mechanical engineers design other machines inside buildings, such as elevators and escalators.
What metal is a washing machine made of?
The outer case and majority part of a washing machine are made of steel, coated with zinc to protect the steel against corrosion (rust). The inner tub of some models is made of stainless steel.
How is a washing machine constructed?
Once the constituent parts have been made, they are assembled; major sub-assemblies, or components, include the transmission, the pump, the spin and wash tubs, the balance ring, and the painted parts. Finally, the sub-assemblies are put together inside the shell of the washer, which is then complete.
Which force is used in washing machine?
centrifugal force
Explanation. The centrifugal force between the clothes and the inside of the drum pushes them around in a circle. This force pushed the water from the clothes straight through the drum holes. The clothes experience the centrifugal force, and the water doesn’t.
What the electric motor does in washing machine?
The motor can be used to agitate the drum (both forwards and in reverse) by switching the field winding with respect to the armature. The motor can also be run up to the high speeds required for the spin cycle. Nowadays, variable-frequency drive motors are more commonly used instead.
What is the working principle of washing machine?
Washing machine motor. This is combined with the agitator or the disc that turns the drum, it produces a rotator motion. This is basically the mechanism that gets your machine going. Drain pipe. All the dirty water from your washing is expelled from the machine via the drain pipe.
What are the different parts of a washing machine?
Parts of the washer. Since each washing machine comes with its own design and features, some of the parts will vary between your machine. But get to know your washer with some common parts you can find in your machine. Water pump. This circulates the water through the machine, rotating in two directions.
What is the function of the water pump in washing machine?
When you load the clothes in washing machine, this valve gets opened automatically and it closes automatically depending on the total quantity of the water required. The water control valve is actually the solenoid valve. 2) Water pump: The water pump circulates water through the washing machine.
What is a PCB in a washing machine?
7) Printed circuit board (PCB): The PCB comprises the various electronic components and circuits which are programmed to perform in unique ways depending on the load conditions (the condition and the amount of clothes loaded in the washing machine).
