මේ වීඩියෝව නැරඹීම තුලින් ඔබට නිවසේ වතුර මෝටරය automatic පාලනය කාරීමේ හැකියාව සහ දැනුම ලබා ගැනීමට පුලුවන්..

වතුර පිරුනාට පසුව මෝටරය Off වෙන්න සහ, ටැංකියේ වතුර මට්ටම අඩු වූ විට මෝටරය off වෙන්න මෙමගින් සකසාගත හැක.

Float Switch Connection with Auto & Manual Selector Switch for Single Phase Water Pump.
In this video, I have explained how to connect the float switch to water pump with auto and manual selector switch.
Normally we use auto mode (Float switch connection) for our ease of works. But if float switch damage, we should have another option to operate the water pump. So we can use manual start and stop connection for the water pump. And also Auto-Manual selector switch should be used to change the auto or manual mode.
If you have any questions, please comment below the video. I will answer your questions.

Float Switch Connection Single Phase Water Pump

what is float switch?
float switch is a type of level sensor a device used to detect the
level of liquid within a tank. The switch may be used to control a pump
as an indicator an alarm or to control other devices. One type of float
switch uses a mercury switch inside a hinged float.
how does a float switch works?
float switch is a type of level sensor a device used to detect the level of
liquid within a tank. one pattern uses a reed switch mounted in a tube a float containing a magnet surrounds the tube and is guided by it. when the float raises the magnet to the reed switch it closes.
Miniature Circuit Breaker
Miniature Circuit Breaker MCB automatically switches off electrical
circuit during an abnormal condition of the network means in overload
condition as well as faulty condition. Now days we use an MCB in low voltage electrical network instead of a fuse.
Magnetic Conductor
Magnetic Conductor is a part or a kit of parts intended for a lossy magnetic
flow generated with current in windings of such devices as transformers throttles magnetic cartridges filters and circuits.
Single Phase
single phase power is commonly found in residences and commercial
buildings and is primarily used for powering small appliances.
This configuration may either be a simple 120V or a split phase
configuration with 120/240V. Single phase is either a two or three wire ac circuit.

ITS IS A VERY USEFUL CIRCUIT AND YOU CAN MAKE AND PREPARE VERY EASILY.

WHAT IS CONTRACTOR AND ITS FUNCTION?

A CONTRACTOR IS AN ELECTRICALLY-CONTROLLED SWITCH USED FOR SWITCHING AN ELECTRICAL POWER CIRCUIT. A CONTRACTOR IS TYPICALLY CONTROLLED BY A CIRCUIT WHICH HAS A MUCH LOWER POWER LEVEL THAN THE SWITCHED CIRCUIT, SUCH AS A 24-VOLT COIL ELECTROMAGNET CONTROLLING A 230-VOLT MOTOR SWITCH.

WHAT IS THE FUNCTION OF OVERLOAD RELAY?

OVERLOAD RELAYS PROTECT A MOTOR BY SENSING THE CURRENT GOING TO THE MOTOR. MANY OF THESE USE SMALL HEATERS, OFTEN BI-METALLIC ELEMENTS THAT BEND WHEN WARMED BY CURRENT TO THE MOTOR. WHEN CURRENT IS TOO HIGH FOR TOO LONG, HEATERS OPEN THE RELAY CONTACTS CARRYING CURRENT TO THE COIL OF THE CONTRACTOR
