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, that also houses components used in the air/oil separation process. This is normally a trouble-free component on. .
Oil from the sump flows through small entry passages around the outside of the filter base and is forced through an opening near the closed side of the filter casing, where it. .
This is our first stop in our trip through the system. This valve will direct our lubricant towards its next component based on temperature. Just. .
This component, like the radiator in your car, passes the fluid through tubing encased in a block of baffles, designed to optimize heat transfer. Most air-cooled air compressors have a high capacity fan which will force air through the baffles, and out of the cabinet,. .
Our next stop, assuming our lubricant has reached its operating temperature will be to the oil cooler. As our lubricant has been subjected to extreme friction and bears the brunt of temperature. Lubricating oil plays a crucial role in screw air compressors, primarily for lubrication, cooling, sealing, and noise reduction. The oil is drawn from the oil tank, filtered, and then enters the compressor. It lubricates the rotors and sealing components, reducing friction and wear.
[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. .
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. .
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.

This is job No. 1. It doesn’t matter how regular you are about maintenance if the person handling the tools doesn’t know what he’s doing. Says Caho: “You need someone who’s actually trained to do it.” From what Caho has seen, that’s easier said than done these days. “One of the bigger problems is that a lot of. .
If you’re maintaining your rig properly, this should be a regular part of your routine. “Those should be checked every day, or even throughout the. .
A checklist creates a sense of organization and accountability on the jobsite. “I’m a big believer in a daily inspection form that has been made up by the company,” Caho admits. “Almost. .
This has become an increasingly important factor in rig maintenance. “Make sure you’re using the specific fluids that the manufacturer or your company has required,” Caho. .
There’s a tendency to take shortcuts when it comes to wearing safety gear. Don’t do it. Personal protective equipment can’t be viewed as an option. You always want to be dressed in a way.
