Impeller Balancing

After the impeller is cropped,next it is balanced before it is sent to the assembly department(fixing of casing and motors).

Only 255mm and 350mm impeller requires balancing at this point of operations.

Static Balancer which compromise of two parallel shafts which are fixed to the bearings.The impeller is fixed with the shaft and placed on the balancer.

The impeller is pushed and forced to rotate on the shafts.If the impeller rotates on one direction and stops after a while,this indicates that the impeller is already balanced.

If the impeller does rotate back after a while,this shows that the impeller is unbalanced.

So,further observation have to be done to find where the weight varies on the impeller which causes it to be unbalanced.

After the correction point/s are found,trial weights are placed on that particular points and the rotation of the impeller is observed carefully.

If the impeller does not rotate back after the trial weights are added,this indicates that the impeller is balanced if not,the steps above have to repeated until the impeller is balanced.

Impeller Cropping

Cutting radius is noted(496mm)

The vertical band saw machine used to crop the impellers

Shaft to pivot impeller and extension bed to rest the impeller

The vertical saw

To set cropping length, measurement

will be taken from the surface of

blade (against the bed rail) to the

centre hole of the shaft

In this case the length is 496mm

Supporting block to hold the impeller while it being cropped

The impeller is placed on the shaft

The impeller is cropped in clockwise rotation

After it being cropped,the will be some remaining on the edge of the impeller

The remainders have to cleaned or shaved

A smoother surface can be obtained

250mm Impeller Assembly

Assembly Jig

Labeled jig

Work Sheet(Details are extracted as below)

H250FPTL(250mm face plate a.k.a FORM A) on the left and H250TL(250mm taper lock hub a.k.a FORM B) on the right

SABL-375 ( left hand aluminum blade 375mm)

AP(aluminum plug suit)

PITCH ANGLE is set to 25 degree

NYLON nut

AIR SWITCH which is used to place the nuts on the jig nut recesses

Nuts are placed on the nut recesses

This unit requires FORM B as the base,so H250 TL is used and the nut recesses are alligned with the nuts

The impeller has a half compliment of blades,so the plugs are placed on each second holes

All of the aluminum plugs are placed

The blades are placed on each vacant hole beside the aluminum plugs(AP)

Complete blades and plugs on the FORM B face plate

FORM A is aligned with the hub of FORM B

After FORM A is attached,all the blades are locked with the retention clips

Blades are locked

Bolts are inserted on each holes on the FORM A plate

All of the bolts are inserted

Each bolts are tighten using the torque screwdriver

2nd day at work!!!

Today i didn't have much to do because for the 1st 2 weeks,i am placed at this impeller assembly department.So,i was just repeating the job i did yesterday.

Since that was the case,my supervisor Mr Nash offered me to help him in the admin department.I was tasked to do data entry for the financial year end stocks.

A software named AUSVANTAGE were used to key in the data's.The same system is being used by the Fantech Australian company.The main purpose of changing the normal traditional way of key-in data's using Microsoft Excel to this software is because via this software,the Australian branch can have a look whenever they feel like checking on the stock incoming and outgoing,damages,quarantines and so on.

I can say that today, i have been in the admin department for about half a day and learned to use a new software.I also did some chit-chatting with the admin staffs.It was fun today.

First day of internship....

Before i start my journal on my 1st day at work,here is a introduction about the company ELTAFANTECH:

I reached my "new" office around 8am.The work starts at 8.30am.My supervisor Mr Nash arrived around 8.25am.Then he took me touring around introducing me to my fellow colleagues from the admin department till production department.

Then,i was briefed by Mr Nash about the company's basic rules and regulation.He also spent some time explaining about the work flow of the production department.

Then i was brought to the impeller assembly department where i met Mr Asif and Mr Munner,(Pakistani).They were very friendly and informative in explaining the procedures and process involved from basic on how to read the details on work sheet till balancing of impeller.

In this company,three breaks are allocated for the employee which is from 10-10.15am(morning break),12.30-1.30pm(lunch) and 3.30-3.45pm(evening break).The working hour offically ends at 5.30pm.If there are additional works to be done in order to meet the delivery due date,then overtime(OT) is needed.

I really enjoyed my 1st day at work and it was fun meeting up new people and learning new things.I hope my 3 months here will be exceptionally beneficial to the company and myself.
