How It’s Work : SMC Auto Drain Functional and Operation

This time I would like to share about Auto Drain operational to discharge automatically water inside compressed air receiver tank.This equipment is very important to remove 80% of water contain in compressed air and to ensure our compressed air is dry and clean.Why we need the clean and dry compressed air in our system?The main reason is to ensure our pneumatic equipment or instrument fully operated and pro long a life span.If water contaminated our compress air system,piping or equipment that operated with compress air will rusty,jammed and clog with dirt.It’s can cause a breakdown and it loss to our operation cost.

Below is example of SMC Auto Drain Operational to remove out water inside receiver tank.We can see a lot of water came out to drainage when auto drain operated.You can image how much water can go through inside to air supply system and can damage our equipment and pipeline.Feel free to watch the video and please share,like or comment if you think it’s benefit.

Basic of automatic voltage regulator

Basically the AVR or Automatic Voltage Regulators function for generator is to ensure voltage generated from power generator running smooth to maintain the stable voltage in specified limit. It can stabilize the voltage value when suddenly change of load for power supply demand.

If the generator running in parallel condition,the AVR can controlled the voltage that it produce to ensure of equal value for reactive load sharing.

For the big system of interconnected power distribution with parallel design,it must have a full controlled and transient stability particular must added for requirement to the Automatic Voltage regulator for generator. read more

Safety interlocking devices

For the electrical power distribution,we used a switch gears to control our distribution power supply to user.One of important things when design the system,we must include with safety interlocking device.

Motor control design also need to attach with interlocking system to ensure the operation is safe for user and can prevent for serious damage of equipment.

Before we design the control circuit or operation sequence,the important aspect that we should consider is about interlocking and must have a deep study to make sure it function properly.

Types of interlocking method

Normally in industry,interlocking devices have a two (2) types of method such as electrical and mechanical control.Their main purposes for interlocking system are  : read more

Automatic voltage regulator for generator

The AVR ( automatic voltage regulator ) is suitable for supplying power to the fields of either brushless or commutator type exciters and will maintain the A.C generator voltage within plus and minus 1% of the preset value with paralleling.

When the load varies between no load and rated load and with a frequency changes more than plus minus 4%.Upon application or rejection of rated load,the generator voltage recovers to plus and minus 1% within 0.3 second on most AVR exciter in A.C generator combination. read more

How to replace new bearing for condenser fan motor?

Have you faced any problem with bearing broken,jammed or stuck for your condenser fan motor?Are you know how to change a bearings unit?It look difficult task but if we have required tools,basic knowledge and passion,I’ve think all of you can do this job.

What we need for this job?The important tools is bearing puller set,combination wrench set,WD-40 (anti-rust),pliers,hammer,screwdriver,grease and cotton rack.

In the maintenance job scope,replaced a new bearing for electrical motor is common jobs..This time i want to show you how to replaced a new bearing for Air-condition Out door unit CONDENSER FAN MOTOR. read more
