Microwave Oven Components-Switches And Transformer

admin — Wed, 16 May 2012 06:41:31 +0000

Switches – The switch component of a microwave oven is very important. Their design must be tested for durability and very high repeat use. The switch connects and disconnects supply to the unit by pressing a button on the front of the oven. When the button is pushed the microwave is either activated or deactivated. It is an electrical switch which requires very little physical force to activate and their durability means they can be used up to 1 million times without failing.

Transformer – The transformer is the microwave component which increases the voltage of the alternating current of the oven, this may be referred to as ‘stepping up’ the voltage. The type of transformer used in microwave ovens is a very powerful component and should not be touched. Transformers usually consist of two wire coils wrapped around a core, called primary and secondary windings.

Checking a Drive Belt

admin — Fri, 13 Apr 2012 01:48:17 +0000

In the market, there are various kinds of mechanical parts. All of them,

small or big, are very important for the whole machine. Among the

numerous components, belts are rather simple and common, meanwhile, they

are also indispensable.

A belt is a loop of flexible material used to link two or more rotating

shafts mechanically. Usually, belts are looped over pulleys. They

cooperate with pulleys very well to achieve certain function. They may

be used as a source of motion, to track relative movement, or to

transmit power efficiently. When the designed belts and pulleys are

working together, then the power transmission can be achieved. Compared

to other parts, belts are the cheapest utility for power transmission

between shafts that may not be axially aligned.

Belts have a wide usage. For example, drive belts are commonly used for

power transmission. It is a seamless belt that is used to transmit

torque and power from one wheel or shaft to another in a machine or any

mechanical system. As is mentioned in the above, the belts work together

with pulleys to have the power transmission. In vehicles, there is a

drive belt system which powers the water pump, the air conditioning,

power steering, brakes and alternator among other components. Because

power is quite important for vehicles to run regularly, obviously, this

important component also plays a very important role in transmitting the

power. As a result, it is very necessary for machine owners to take care

of the drive belt and check it on each time they change the oil. This

intends to ensure that it is working regularly without any problem,

which will also guarantee the proper work of the whole system.

Three paces For Check A Drive Belt

admin — Fri, 13 Apr 2012 01:47:03 +0000

Firstly, the tension and general condition of the belt should be

checked. This step is very useful to ensure whether the vehicle is in

proper condition. When inspecting the drive belt, you should pay

attention to many aspects. For instance, cracks, the presence of frays,

and missing ribs, etc. Any of these problems should be dealt with.

Secondly, you should ensure that you inspect the entire length of the

belt surface. Except the above mentioned elements, sometimes, vehicles

may produce a squealing sound which may be a sign of losing or wearing

out of it. This is because a loose belt may slip and subsequently

produce a squealing sound, causing the alternator to vibrate rapidly,

thereby wearing it out more easily. If the sign of wearing out is quite

obvious, it is better to replace the drive belt to ensure the safety.

Addition to the above aspects, it is also very important to inspect the

drive belts before problems appear. If there is any problem with the

drive belt, you should find out the reasons. And you should replace the

drive belt if necessary. The proper status of the drive belt may ensure

that the vehicle can run under a good situation.

The king of plastics-PTFE

admin — Fri, 06 Apr 2012 06:46:16 +0000

Owing to its wide application, PTFE is called “the king of plastics”. It is a kind of synthetic polymer material. The skeleton of PTFE is carbon atom. And the fluorine atom is evenly distributed around the carbon atom and forms the compact protective screen. Therefore, PTFE has the very excellent physical mechanical property. It can not only resist the strong acid, strong alkali and strong oxidant but also can bear high temperature. To some degree, its property surpasses the property of glass, ceramic, stainless steel and gold. Its working temperature ranges from-100 to 100 Celsius degrees. Its working pressure is 10 MPa. What’s more, PTFE does not easily become aged or is not easily burnt. The property of the water absorption is almost equal to zero. In the normal situation, the PTFE has no harm to people’s health, but in the course of production some raw materials are regarded as the carcinogenic substance. With the invention of PTFE, it is of great significance for the industry, because it solves a lot of problems in the chemical sector, oil industry and pharmacy industry. It has been widely used as the main sealing material and filling material.

principle of PTFE

admin — Thu, 05 Apr 2012 08:42:51 +0000

PTFE is engineered with a ratio of four fluorine atoms to every two carbon atoms. This means, that the carbon center of the molecule is shielded by fluorine atoms. This means that molecule is almost essentially totally shielded from contact with other molecules. This means that it’s virtually impossible for any other substance to reach the carbon atom. Because of the substance’s unique carbon to fluorine ratio, its bond is just about unbreakable. However, this is not all. The chemical fluorine is also severely anti-social. Put quite simply, it wants nothing to do with other atoms. It is the loner of the chemical world. As part of the PTFE compound, it’s “goal” is to stay alone and avoid all contact with other atoms. Because of this, anything that comes close is pushed away and doesn’t stick to whatever surface is coated with PTFE. For this very reason, PTFE is used worldwide as the world’s most slippery material.

If you Aren’t Looking For The Best Car Polish

admin — Tue, 27 Mar 2012 01:16:11 +0000

If you aren’t looking for the best car polish out there, then you should be, and you should be for several reasons. Apart from your car being your pride and joy and a big investment, you need to remember that your vehicle is under constant attack by the sun’s ultra violet rays, industrial fall out and acid rain. If your car is left unprotected from these elements then the paintwork will surely suffer irreversible damage.Most car protection products out there are made from waxes, and just like any wax does when subjected to the suns heat, or any other heat, it starts to melt and deteriorate. Then you buy more, and you wax your car again, and the car waxing companies are growing bigger and bigger all the time as you part with more and more cash.

Well did you know there’s a product out there that has been around for a while now; a product that only usually shows itself when a new car salesman asks you if you want to spend more of your hard earned cash on having your new car paintwork protected. Of course most people would spend the extra few hundred on top of the few thousand already spent to protect their new pride and joy.What they are generally using to protect your car is PTFE car polish and this is the most slippery substance in the world. It has now been introduced into the car market in various different forms, and produces astounding results.PTFE is not only used in car protection products but also in the marine and aviation industry and has even become a big player in both the caravan and the motorhome market. It simply cannot be ignored as an excellent paintwork protector.

Chosing PTFE Teflon Low Friction Coatings

admin — Mon, 26 Mar 2012 01:56:22 +0000

PTFE, also known as polytetrafluoroethylene, exceeds many of the properties of other thermoplastics. Let us look at its surface characterizations for adhesion and deformation when sliding wear is considered against metal.Based on its comparatively low modulus value, any surface asperities of DuPont PTFE will measurably deform under load. This means higher loads can produce lower friction.Of course, coefficients of friction will rise with increasing temperature. Mostly the result of binder choice within the coating, so be sure you can identify your temperature requirements. Once you reach upper limits of continuous use, melting point, or glass transition temperature, drag can increase significantly.Sliding wear is normally measured by material loss over time. So consider these two primary mechanisms for wear: adhesive wear and abrasive wear. Between the two, adhesive wear will always be preferable.

How do you distinguish between the two forms of wear? Well, if it is adhesive wear, you should see developing fine powders at the interface between the fluoropolymer coating and metal counter face. This is a good indication that surfaces are wearing the way they should. However, phenomena like deep corrugations, grooves, or gouges within the coating will quickly indicate pressure velocity limits of the material have been violated. Usually, too, assuming the environment remains unchanged, abrasive wear occurs quickly. Sometimes, failure is immediate and catastrophic.
