What are the different parts of stand fan?

Answer 1

Parts of the Electric Fan

· Front Guard. It is a protective metal mesh wire used to prevent the fan

blade from any physical contact with foreign objects.

· Power Controller. It is a circuit that controls the amount of power supplied

to the motor.

· Sensor. It is the input receiver that detects input signal coming

from remote control.

· Manual Control. It is a push button switch that controls manually

operation of the electric fan.

· Non-polarized Capacitor. A low reactance non-polar capacitor connected in

series with the start winding of an electric fan.

· Timer. It is used to switch on or off automatically with

predetermined time.

· Comparator. It is a processing circuit that accepts the input signal

coming from remote control, manual switch or timer switch. This circuit provides the triggering voltage to the power controller.

· AC Motor. It is rotating electric machine which changes applied

electrical energy or power into mechanical output energy or power.

· AC Plug. It is a connector intended for connecting to the main

source 220 V.

PROCEDURE IN PREPARING AN ELECTRIC FAN

1. Once the specific electrical/mechanical problem is located;

· Consider the techniques for the proper removal of the detective component or parts.

· Anticipate what to do if the replacement part does not correct the problem.

· Check the installation of the replacement or original part for any improper mounting in the mechanical assembly or circuit board.

2. Examine carefully the mounting of the replacement of original parts of the system.

· Check the placement of the wires or loads of the replacement component

· Consider significant factors used in the original installation such as insulating washer, silicon grease and locating mark for pin connections

· Observe proper placement of the component leads for electrical parts

3. Perform the techniques for the proper soldering of electrical parts.

· Be careful not to damage adjacent components

· Be careful not to lift the copper conductive path from circuit board base material

· Avoid any solder bridges between board path

· Do not destroy the component being removed in case it is still functional and be careful not to damage the component being installed

4. Verify all connections and harness.

· Be sure that all components pre-positioned in a manner that will avoid the possibility of adjacent component short circuit conditions

· Be sure to check or inspect all insulators and barriers between sections after working on any model/brand of electric fan.

· Checked for frayed or broken insulation on all wiring including the AC line cord

· Be sure to replace fuses, resistors and capacitors with special designation such as flame proof to components equal to the original value for both safety and liability purpose

5. Once the repair is completed, perform an AC leakage test on all exposed metal parts of an electric fan to eliminate the possibility of electric shock

· Perform complete retesting of the electric fan to ensure the correctness of the actual repair

· Connect the electric fan into the 60Hz power to allow the time period required to let the new parts settle in and operate as they are designed to work with each other.

· Recheck or inspect if the repair was done correctly and the unit functions properly to ensure successful completion of the repair

6. Clean the electric fan before it would be returned to the customer.

· Be sure that the blade, front and rear guards of the electric fan are properly cleaned

· Be sure that the power cleaning is given to the control panel or switch box of the electric fan.
