How to Align Your Shafts

Written by Thomas Yoon

Inrepparttar last issue, we discuss about shaft seals and how liquid is prevented from coming out fromrepparttar 100075 pump housing even though repparttar 100076 shaft is rotating. Ezine Article

Some mechanical seals are made to very fine tolerances. Damage to mechanical seals and bearings can sometimes be cause byrepparttar 100077 misalignment of pump shaft withrepparttar 100078 motor shaft.

Whenever some ofrepparttar 100079 motors or driven machinery is dismantled or even whenrepparttar 100080 machines are not running smoothly, alignment has to be done.

The purpose of alignment is to ensure thatrepparttar 100081 centerline of repparttar 100082 motor rotor shaft coincides exactly withrepparttar 100083 centerline of repparttar 100084 driven machinery. Alignment is essential to ensure thatrepparttar 100085 machine runs smoothly with minimum vibration.

Providedrepparttar 100086 two shafts are not bent crooked,repparttar 100087 two alignments to be checked and adjusted are: Offset alignment and Angular alignment.

Most alignments are rough alignment that can be done using straight edge ruler and feeler gages. However for precision alignment,repparttar 100088 use of dial gauges with magnetic bases can be used.

Offset Alignment

The radial alignment is checked using a straight edge ruler. By placingrepparttar 100089 ruler acrossrepparttar 100090 coupling halves atrepparttar 100091 top, bottom and both sides any gaps betweenrepparttar 100092 2 coupling halves will indicate thatrepparttar 100093 shaft is offset slightly. The misalignment can be corrected by shiftingrepparttar 100094 motor or by putting shims to raise uprepparttar 100095 motor or driven machine.

I recently had a customer ask for my advise about cleaning her refrigerator.

I started to describerepparttar pros and cons of different cleaners that can be used to cleanrepparttar 100074 interior when she stopped me abruptly. “I know all about that stuff ”, she informed me, “I meanrepparttar 100075 black coil thing onrepparttar 100076 back”.

So, in response to this common question I offerrepparttar 100077 following step-by-step directions.

Firstly,repparttar 100078 ’black coil thing’ atrepparttar 100079 rear ofrepparttar 100080 refrigerator is called a condenser. Without too much technical jargon, its job is to dissipate heat intorepparttar 100081 kitchen. It does this byrepparttar 100082 condensation ofrepparttar 100083 refrigerant gas. Hence, its name. The condenser tubing is usually seen onrepparttar 100084 rear of a refrigerator. It is produced in a serpentine form with additional fins running across it for added heat dissipation.

“Heat, I thought we were talking about refrigerators, not stoves”.

You will have to believe me when I say: ‘a refrigerator does not produce cold air’. Rather, its job is to transfer heat from insiderepparttar 100085 refrigerator cabinet torepparttar 100086 outside. While doing this it removes heat from your food and that results in your food becoming cold.

So, who cares! You should. Because a major part in this transferring of heat isrepparttar 100087 ‘black coil thing’ we have been talking about. Yes, that’s right,repparttar 100088 condenser.

Withoutrepparttar 100089 condenser our refrigerator would not operate. Therefore, we are going to learn how to do basic maintenance of this part and keep our refrigerator in tip-top shape.

------------------------------ So let’s begin

Tools required: ·Vacuum cleaner ·Brush or vacuum brush attachment ·Cotton rag ·Light strength household cleaner ·Garbage bag

1.Pullrepparttar 100090 refrigerator away fromrepparttar 100091 wall and unplug it.

2.The condenser will berepparttar 100092 radiator-looking part onrepparttar 100093 rear ofrepparttar 100094 refrigerator.

3.Use a brush or vacuum cleaner to remove any dust buildup onrepparttar 100095 condenser. Remember,repparttar 100096 condenser is made of thin tubing and is full of a high-pressure (130 psig) gas. So be gentle. If you injurerepparttar 100097 tubing a simple cleaning could turn into an expensive repair.

4.If you have a pet expect to see a large accumulation of animal fur onrepparttar 100098 condenser. If a lot of dust or fur is present then clean off with a dry rag and dispose intorepparttar 100099 garbage bag. We suggest usingrepparttar 100100 dry rag method first to avoid clogging uprepparttar 100101 vacuum hose.
