The Three Types of Air Compressor

Wednesday, May 12th, 2010

Piston Compressor

The piston compressor has been around the longest but is still a popular choice. The piston compressor works by the piston moving forward in a cylinder by way of a connecting rod and crankshaft. There are two ways of using a piston compressor; if just one side of the piston is used for compression, it is known as single acting. If both the top and bottom sides of the piston are used, this is double acting.

The piston compressor is capable of compressing both air and gas with only slight alterations. It is the only compressor that is accomplished at compressing gas and air to high pressures, for equipment such as breathing equipment.

Rotary Screw

The screw compressor is the most prevalent compressor in use today. The rotary screw consists of male and female rotors which move towards each other, decreasing the volume and the housing between them. The length and shape of the screw determine the pressure of the screw as well as the form of the discharge point. The rotary screw is able to work at high shaft speed and combine a sizeable flow rate with small exterior dimensions. They are suitable for pharmaceutical and food and beverage manufacturing, among others.

Rotary Vane

The rotary vane is the undisputed most reliable air compressor on the market today. It is driven directly, at extremely low speed. The rotor moves constantly and comprises of sliding vanes which move along on a film of oil. These vanes slot into grooves on the rotor. Pressurized oil injection controls the heat which is generated through air compression. Rotary vane air compressors are used for dentistry, printing and packaging.

Full Round Head Nails versus Clipped Head Nails

Tuesday, May 11th, 2010

The question of whether full round head nails or clipped head nails are better is frequently asked by consumers.

Some people prefer full round head nails as opposed to clipped head nails because they think that they are more robust but it is actually the shank that gives most of the support. The head of the nail only begins to play a role when there is withdrawal; when the nail begins to slip out of the wood. The head prevents the upper and base materials from separating and also from pull through; this is when the nail head is dragged through the upper material

Advantages of clipped head nails are that they are smaller, so more can be fitted into a nail gun magazine. This saves time because the nail gun does not require to be reloaded as often. It also means that the nail gun itself is smaller and therefore lighter.

Full round head nails are generally preferred in hurricane-prone regions of the world as they are less likely to be overdriven into the walls, which can cause building failure.

Brad and Finish nails have rectangular heads that that the same width of as the shank, but a larger breadth. This makes the shank more resilient than both full round head nails and clipped head nails and also decreases the pull through pressure.

Variable Speed Air Compressors

Thursday, May 6th, 2010

Ace Compressors offer a range of variable speed air compressors that can prove to be highly beneficial for your business. There are many different advantages of using variable speed air compressors instead of fixed-speed compressors, for example; reductions in power cost and power surges and also the delivery of more constant pressure.

Different products require different speeds, so by adjusting the speed of the variable speed air compressor you will accomplish smoother operation and allow more accurate positioning.

 Compressed air is usually 20% of a factory’s electricity bill, part of which will be lent to wasted energy. Significant savings can be made by using variable speed air compressors and they also have a lower impact on the environment, which as a business, you should make one of your primary concerns.
