There are two basic types of screw compressor: oil-injected and oil-free. Oil-injected rotary screw compressors are the most common, since they are the cheaper ones of the two types. Oil-free screw co. [pdf]
A rotary-screw compressor is a type of , such as an , that uses a rotary-type positive-displacement mechanism. These compressors are common in industrial applications and replace more traditional where larger volumes of compressed gas are needed, e.g. for large refrigeration cycles such as , or for compressed air systems to operate air-driven tools such as and . For smaller rotor sizes th. [pdf]
A is first thought to have been used for rock drilling in 1844. Many quarries used hand held tools that required the driller to suspend himself from a rope over the quarry face in order to place the drill hole in the required position. This system used small diameter holes and was not only terribly inefficient, but very dangerous due to flying rock as a result of the inaccuracy of the drilled borehole. [pdf]
The longer your feed rail, the more important the addition of the energy chain becomes to the overall effectiveness of your machine. We offer a range of feed rail options from 6′ to 24′ for our Skid Steer and E. [pdf]
In this write up I have explained a couple of these simple infrared remote control circuits designed for controlling any given electrical appliance through an ordinary or TV remote control unit. .
Controlling household electrical gadgets or any electrical equipment remotely can be fun. Controlling gadgets like a TV set or a DVD player through. .
The second IR remote control circuit discussed below uses a unique frequency and detects only the specified IR frequency from the given remote transmitter unit, making the design entirely failproof, accurate and reliable. .
Here's a straightforward infrared switch designed for remote control purposes. It utilizes a typical IR LED and IR diode detector pair,. .
The solution comes easily due to the inclusion of the versatile IC LM567. The IC is a precise tone decoder device which can be configured to detect only a specified band of frequency, known as passband frequency. Frequencies not falling within this. [pdf]
A flow control valve regulates the flow or pressure of a fluid. Control valves normally respond to signals generated by independent devices such as flow meters or temperature gauges. .
Control valves are normally fitted with and positioners. -actuated and are. .
Process plants consist of hundreds, or even thousands, of control loops all networked together to produce a product to be offered for sale. Each of these control loops is designed to keep some important process variable, such as pressure, flow,. .
