Grouped control mechanism, quick of start up, with “air-on, water-on, air-off, water-off” mechanism, easy operation and maintenance. Low noise, small vibration, energy-saving and efficient, highly interchangeable parts with long service life, reliable performance. [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]
These hammers use a low air pressure range of around 12 to 18 bar, which is significantly lower than the pressure used by conventional high-pressure DTH hammers. This means that they produce less noi. [pdf]
In 2010, Schramm, Inc. assisted in the rescue of 33 miners trapped for 69 days as a result of the in . The company built both drilling rigs that were key in saving the miners. The Schramm T685 WS truck mounted drill bored a 5.5 inches (14 cm) hole that, on 22 August 2010, was the first to break through to the 33 trapped men, confirming they had survived the accident. The company also manufactured the T130XD drilling rig owned by Geotec. [pdf]
Either an electrical problem, or the compressor has tripped on a safety device. Check supply power. Check for errors on display. Check emergency stop is out. Check and reset the overload relay. If it’s a new installation, check the phase sequence. Ambient temperature too high or not enough ventilation. [pdf]
Luckily, I’ve got you covered with 5 reasons why your air compressor is slow to build pressure — and how to fix them. A slow-building air compressor can be frustrating, to say the least. But more than this, it can actually damage the compressor if you continue to run it without addressing the issue. .
If a compressor’s pressure valves (sometimes called flappers or reeds on reciprocating air compressors) are failing, the pressure won’t. .
An air compressor operates with a pump, which pulls air into the compressor. These pumps have piston rings that act as seals and prevent oil from too much oil getting into the compressor’s. .
A failure of the intake valve causes a similar problem to that of a failing flapper or pump pressure valve. When an intake valve is going bad, the compressor will take air in, but the air. [pdf]
Dry screw vacuum pumps require no water or oil for sealing or lubrication in the vacuum stages. Consequently, these dry vacuum systems eliminate effluent generation, pollution,. .
VSB dry screw models operate at any pressure between blank of and atmospheric pressure. Pumping capacities are virtually limitless when paired with a high vacuum booster pump. .
The VSB Series low rotational speed ensures smooth and robust operation. Engineered to offer higher discharge pressure handling capabilities than vertical designs, allowing for more process time. With higher vapor and liquid tolerances, dry screw vacuum. [pdf]

We will start our trip through the loop at the same place we will finish: The oil sump. This reservoir is where oil is stored for use in the system. It is usually located in the lower section of a tank-like cylinder. [pdf]
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 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. The system is thought to have been invented independently by Stenuick. Origin of the nameDTH 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 mechanis. .
In DTH drilling, the percussion mechanism – commonly called the hammer – is located directly above the drill bit. The drill pipes transmit the necessary feed force and rotation to the hammer and the bit, along with the flui. [pdf]
