Belt & Direct Drive Turntables to Rule Your Senses

Turntables are one of the best ways of enjoying your old vinyl music, as the modern turntables are able to convert the analog music of vinyl to digital music. USB turntable is the best ways of doing so; it just requires connecting the turntable to your computers and the conversion of music from analog to digital takes place by employing certain steps. The market is full packed with a range of turntables that are available. They are meant to provide the best and the quality music at the most affordable price.

Turntables are available in two type viz. the belt drive and direct drive types. These are named so due to their drives need to operate them. These are meant to play 12″ and 7″ vinyl discs.

In case of a direct drive type, the motor is placed right under the center of the platter which is connected to the platter directly. The first direct-drive type commercial turntable is introduced to the market was SP-10 by Matsushita.

Since the introduction of first turntable a lot of advances have been made in it and the newer models are continuously replacing the older one. Even after the continuous improvement, the technologies used remain the same in it.

In direct-drive type, a shock absorbing technique is introduced with the addition of shock-absorbing material between the motor and platter. It exhibits the advantage of quick start of the system and one can turn off the system and can make any sort of adjustments and the speed is quickly regained by the system.

The disadvantages associated with direct drive type are:
It suffers from the vibrations that are generated due to the motor.
The torque of the direct drive turntable is on the higher side as compare to the belt drive type.
They tend to transmit more noise generated by the motor and bearing.

The belt drive type turntable exhibits a motor that is located right under to the side of the platter. It is then connected to the platter with the help of elastomeric belt. The elastomeric belts used absorb the motor vibrations which otherwise would have taken by the stylus.

Initially the problems inherited with the belt drive type music system such as the belt instability and deterioration have been resolved to great extent with the improvisation. Most of the belt drive turntables exhibit multiple speed that employee simple mechanical system to change speeds.

The disadvantages associated with the belt-drive turntable are as follows
Due to continuous use, the belt of the machine tends to lose or wear its elasticity. This will cause the belt to slip which will result into variations in the platter speed.

This type of equipment exhibit lower torque as compare to direct-drive type which may result into the slipping of belt off the motor and consequently affecting the speed of the platter.

The entire market is full packed with various music systems but USB turntables have secured a very significant position. This is because most of the renowned brands such as Garrad, Pioneer, Thorens, Kenwood, Numark offer best and the most efficient systems for quality music.

Problems and Defects of ERW Steel Pipe

The problems and defects of ERW steel pipes are related to raw materials, production methods, process conditions, equipment status and personnel. Product defects that occur in the production process due to the above factors and restrictions.

This kind of product defects can be roughly divided into two categories: one is product defects, that is, the defects in the product itself are inconsistent with the product standards; the first type of defects generated during the production process does not form the requirements of the product standard items, but is also the product quality The problem, its development trend will inevitably lead to product defects. Therefore, such defects are not allowed in the production process.

Process defects

No burr: burr welds. Outer burr is generally better when the watertight test water pressure. But for Ling, bending, flattening test, weld most cracking.
Peach tip: weld at no glitches, and recessed within the wall, forming the tip shape of peaches, try water pressure when water-tight. But bending, flattening test, weld multiple cracking. Within the burr unilateral: watertight seam burr for the side extrusion test water pressure. Bending, flattening test, sometimes cracking.
Burnt: the outer surface of small pits in the weld, welding sparks a lot of splash, the microstructure observed small holes watertight when the test water pressure, bending, flattening test, most will not crack, but the impact on the intensity of use and life expectancy.

Weld defects

Opening: straight weld plate edge face melting traces or melting traces without welding, crack two tip along the weld direction, expansion, penetrate the inner surface of the test water pressure, leaking.
Crack: micro-crack crack; the outer surface of the visible appearance of fine lines, the inner surface of intact, no leakage in the test water pressure, but when crushed or cold-formed crack.

Lap welding: two edge dislocation in the welding, scraping, except burrs can still see the obvious one side higher and exceed the wall thickness of the negative deviation.

Surface defects

Scratch: the general was the axis of the straight channels and scratches, deeper than the wall thickness of the negative deviation of scrap defects in the weld on both sides of a continuous nail-shaped scratch. Super wall thickness of the negative deviation. Waste big flaw.
Correction hurt: the leveler spiral crushed obviously feel more than the wall thickness of the negative bias of – waste defect.
Pockmarked face: the tube surface successful piece punctate small pits with a diameter of about 1mm.

Warp: the pipe surface warping the separation of the part and the metal substrate into pieces, not continuous, spalling can not afford.

Successful Direct Mail Advertising

Direct mail advertising is definitely a beneficial form of advertisement to any business if it is handled correctly. It might seem that sending out a letter, coupons, or postcard might be a relatively simple task, but it is actually more involved than you might realize.

After that comes the question of what exactly are you going to send out, letter or postcard? This seems like a really easy question, but in actuality making the wrong choice can be detrimental to a marketing campaign. It might sound a little dramatic, but the difference between successful marketing and unsuccessful marketing can mean a great deal to a business in terms of profit or lack thereof.

Think about it from the perspective of a customer since you yourself are a customer to many other businesses when you purchase a product or service. When you get your mail do you cringe when there is a stack of junk mail tossed in with your bills? How much attention do you really put into looking through all of the different advertisements? Most customers might take a glance here or there, but usually the majority of those advertisements end up in the trash.
