Automatic Timer switch for Water Pump

This diagram shows the Timer connection with Water Pump. When it's required to control the power of a pump, here the most effective and common option is to use a pump timer switch. A pump timer switch automates your water pumping system and can be determining when the pump starts and stops. The switch can be programmed to turn on at set times throughout the whole day or night, allowing you to save energy. In this circuit diagram, we connect a single-phase motor with a Timer. The timer power source is connected from DP MCB ( Double Pole Miniature Circuit Breaker).

Components used to make the Timer switch for Pump:

01. Single Phase Motor

Fig 2: Single Phase Motor

Single-Phase Induction Motor is Very Simple in Construction, Economical, Reliable, and Easy to Repair And Maintain. Due to all these advantages, it is widely used in vacuum cleaners, fans, centrifugal pumps, blowers, washing machines, etc. It can run only by supplying 1 phase current through this motor. The main two parts of this motor are Rotor and Stator. Among them, the rotating part is the Rotor and the stationary part is the Stator. Like all induction motors, a single-phase induction motor consists of two main parts, the stator, and the rotor.

02. DP MCB

Fig 3: DP MCB

Double pole MCB can control two wires. This circuit breaker is generally used in single-phase electric lines. Double pole MCB circuit breaker input has two wires supply two wires and an output. In a single-phase line, A double-pole MCB circuit breaker is used to give good production. This circuit breaker is provided through phase and neutral circuit breaker, it is very safe. This circuit breaker is preferred for home appliances. A DP MCB usually trips for 2 reasons 1. Overload 2. Short circuit.

03. Timer

Fig 4: Timer

Timer is a specialized type of clock used for measuring specific time intervals.An electromechanical cam timer uses a small synchronous AC motor turning a cam against a comb of switch contacts. This type of timer often has a friction clutch between the gear train and the cam, the cam can be turned to reset the time.A simple example of the first type is an hourglass. Working method timers have two main groups: hardware and software timers.Most timers give an indication that the time interval that had been set has expired.

Frequently Asked Questions

Can you put a timer on a water pump?

When it's required to control the power supply to a pump, one of the most efficient options is to use a pump timer switch. A pump timer automates your water pumping system, determining when the pump starts or stops. The switch can be programmed to turn on at set times throughout the day and night, allowing you to save energy.

How does the automatic water pump switch work?

Here's an automatic water pump controller circuit diagram that controls the water pump motor. The motor gets automatically switched on if the water in the overhead tank (OHT) falls below of the lower limit. Similarly, it gets switched off tank is filled up.

What is the principle of the timer switch?

With timer operation, the Time Switch controls the output according and the set ON or OFF times. With pulse-output operation, the Time Switch outputs a pulse of the specified time width at the set ON time. The power supply was turned ON by a Time Switch.

How do you control a water pump?

A simple way of controlling pumps is the use of inverters, converters, or frequency inverters. The rotational speed was varied by controlling the amplitude, or by changing the frequency.

What kills water pump?

But in most instances, water pumps fail because of the shaft leaks. Water pumps also could be the victim of cavitation inside the coolant system. The movement of the impeller blades in the coolant could create the flow that generates cavitation. Superheated vapor pressure could occur and eat away and the metal.
