You’ll see how Wemano ensures precision, quality, and durability in every air compressor we build. [pdf]FAQS about Screw air compressor assembly video explanation
What is a screw compressor?
A screw compressor is a type of rotary compressor which compresses air due to screw action. The main advantage of using this compressor is that it can supply compresses air continuously with minimum fluctuation in delivery pressure. It is usually applied for low-pressure applications up to 8 bars.
How does a screw air compressor work?
How a Screw Air Compressor Works The screw compressor traps air between two meshed rotors, the air volume is then reduced as it moves through the rotors. The reduction in volume results in compressed air which is then used for a variety of applications.
What is a liquid injected screw compressor?
In liquid-injected screw compressors, a liquid is injected into the compression chamber and often into the compressor bearings. Its function is to cool and lubricate the compressor element’s moving parts, to cool the air being compressed internally, and to reduce the return leakage to the inlet.
What is a rotor in a screw compressor?
Rotors are forged from normal carbon steel and must dynamically balance after machining. Sleeve bearings are used as shaft seals within the compressor. In a screw compressor one of the shafts is driving shaft and the other is driven shaft.
Drilling video of a small down-the-hole drill
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]FAQS about Drilling video of a small down-the-hole drill
What is a down-the-hole drill?
A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud). The DTH hammer is one of the fastest ways to drill hard rock.
What is down-the-hole (DTH) drilling?
Down-the-hole (DTH) drilling has made it easier for contractors to drill wells faster and more efficiently, and to transition from dirt boring to rock boring just by adding a compressor and hammer to the drill bit.
What is a DTH drill rig?
A down-the-hole drill, usually called DTH Drilling Rig, is basically a mini jackhammer screwed on the bottom of a drill string. The speedy hammer activity breaks hard stone into little flakes and dust and can be dismissed evident by the air exhaust in the DTH hammer.
How long did it take to drill a 12,000 ft hole?
The original estimate for completion of a 12,000-foot hole was 30 days using the conventional rotary technique, which was reduced to 13 days using the DTH method. Before DTH was used, drillers would typically case the vertical portion of the well and convert to rotary drilling to drill at a tangent.
How was a hole drilled?
This system could not guarantee a finished hole size and only pure vertical holes could be drilled as the system basically relied on gravity. Debris from the hole was baled out using a baling tube with a clack valve, which was periodically dropped on a winch to capture the slurry, which was then brought to the top of the hole to be discharged.
How does a drill work?
This action along with the rotational movement of the drill string crushes the rock efficiently. Since the piston strikes directly on the bit, energy transfer takes place down the hole with minimum loss of energy, allowing drilling to greater depths. The driving medium i.e. compressed air is also the flushing medium.
