Some people do not concern about the correct method to storage the electric motor.This matter look like simple and easy but if we not take serious action,it can cause serious damage and involve high cost for repairing when electric motor defect due to not proper storage method. I hope my post this time can make [...]
Why cooling system for transformer very important? The amount of heat from a transformer typically dissipated is about 12.5 watts per square meter of surface area per degree C.It also can prolong the transformer life span if it running in normal temperature without exceed the maximum limit. Normally transformer installed in special area or room [...]
Electrical motor is a common used in industrial for many application.This time i want share the basic knowledge for electric motor.Before we go further about how to troubleshooting,repairing or installing,firstly we must know roughly about the electrical motor component. For electrical person,electric motor components basic knowledge should familiar because we can easily understand operation and [...]
When install new air-conditioner or replaced new compressor or change new expansion valve,we need to evacuation or vacuum process.This is important to ensure no air inside the piping system.For easy understanding,this process is to vacuum the system to take out the air and moisture. If air remain in the air-conditioner and refrigerant piping,it will affect [...]
To ensure our air-conditioner running in good condition, we must perform periodical services at least every 6 months.Why we must care and cleaning our air-conditioner? The main cause when our air-condition have a low performance came from dust filter is dirty,it will cause a low cooling capacity,increase electricity cost,unpleasant smell and purified air to our [...]
In air-condition system,compressor is a main component to pump the refrigerant circulation in system.It like our heart to pump a blood all around human system.If this part breakdown or have a problem,all system is paralyze. Normally for single phase air-condition system,the common type of electric motor is running capacitor motor and used scroll type compressor.The [...]
This information is very useful when we selected the electric motor.From this data we can estimate the type of motor and the suitable application to ensure it running full capacity and more efficiency. This is a basic data that we can get from electric motor name plate.Normally it tell about enclosure,motor frame,and bearing.This information can [...]
