Measuring the Free Air Delivery (FAD) of an air compressor can be challenging. With a proper flow meter and some mathematics this task is manageable. This article sheds some light on how to select the flow meter and summarizes parameters to be considered in the FAD measurement task. .
Flow is measured in volume per unit of time. But air can be compressed easily and its volume changes with the temperature. Meanwhile, the air that an air compressor sucks in. .
There are a couple of parameters that affect the efficiency of air compressors. The following table lists these parameters and their effects on two common air compressor types â. .
Recently some manufacturers, especially from China, have introduced thermal mass flow meters to be installed at the intake side of the air. .
The discharge flow of an air compressor contains air, water, oil and particles. Some measuring methods fail because they cannot handle water and oil in the flow. Others are not. [pdf]
Rotary drills, on the other hand, make the bit penetrate the bedrock by quasi-statically pushing the bit into the bedrock. It is therefore the down pressure (thrust) on the bit that contributes significantly to. [pdf]
If you’re more of a visual learner, then we’ve got you covered. The video below addresses these problems and demonstrates how to wire to a pressure switch for air compressors. .
To help you better understand the wiring process, here are four common mistakes seen in air compressor pressure switch wiring: 1. Direct motor wiring:A problem one may often see is wiring directly to the compressor motor, bypassing the pressure switch. This bypass. .

Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure. Various units are used to express pressure. Some of these derive from a unit. .
Pressure is the amount of force applied to the surface of an object per unit area. The symbol for it is "p" or P. The recommendation for pressure is a lower-case p.. .

If your water pressure or flow rate is suboptimal, you can make a few upgrades to your plumbing system to improve it. We’ll list three of the best options below. Just remember that these should all be done by a prof. [pdf]
Drilling vertical holes can be challenging, and even if you are an expert in the use of drill bit, you can never rely only on your hands to drill vertical holes. You will need some tools or accessories like the drill pre. [pdf]
A down-the-hole drill, usually called DTH by most professionals, is basically a screwed on the bottom of a . The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or ). The DTH hammer is one of the fastest ways to drill hard rock. The system is thought to have been invented independently by Stenuic. [pdf]

Years ago I was captivated by an artisan working on jewelry at a Renaissance festival. She was creating a necklace using Tiger’s Eye and drilling out a hole with a hand-powered drill. I was just as impress. [pdf]
DTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling applications, its name originated from the fact that the percussion mechanism followed the bit down into the hole. Applications were later found for the DTH method underground, where the direction of drilling is generally upwards instead of downwards. [pdf]
