What is a down-the-hole drilling rig

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. [pdf]

The screw air compressor is full of air pressure and keeps pumping What s the problem

Check the fuse, motor, and thermal relay and other equipment. Ensure that these devices are in a normal operating state. If there are problems or hidden dangers, relevant measures need to be taken to replace these devices in time. Check the pressure and temperature sensor and start button.. Check the fuse, motor, and thermal relay and other equipment. Ensure that these devices are in a normal operating state. If there are problems or hidden dangers, relevant measures need to be taken to replace these devices in time. Check the pressure and temperature sensor and start button.. A screw compressor can run loaded ('pumping air') or unloaded ('idle'). The inlet/loading valve opens and closes according to air demand. The inlet valve is controlled by a solenoid valve that supplies control air to the inlet/loading valve. Check solenoid valve coil and solenoid valve operation.. The main causes involve improper slide valve positioning, component wear, insufficient voltage, pipeline vibrations, and inadequate oil levels.. The inlet valve is controlled by a solenoid valve that supplies control air to the inlet/loading valve. Check solenoid valve coil and solenoid valve operation. First, check that there isn’t a very high air demand, or air leak somewhere. Check differential pressure over oil separator. [pdf]

Why does the screw air compressor radiator leak oil

The causes of air compressor oil leakage include phenomena such as oil seepage, oil dripping, and oil spraying, which are usually caused by seal failure, loose connection parts, or blockage of the oil cooler. Oil seepage usually stems from the aging of seals or loose connections.. The causes of air compressor oil leakage include phenomena such as oil seepage, oil dripping, and oil spraying, which are usually caused by seal failure, loose connection parts, or blockage of the oil cooler. Oil seepage usually stems from the aging of seals or loose connections.. First, check that there isn't a very high air demand, or air leak somewhere. If the capacity of the air compressor is really too low, check the following: Check differential pressure over oil separator. Replace separator when necessary. Check and replace compressed air filters (if installed).. Excessive Oil Pressure: If the air compressor is operating at excessive pressure, it can put undue stress on seals and gaskets, causing them to fail. Improper Oil Level: Maintaining the correct oil level is crucial. Overfilling or underfilling the oil reservoir can lead to leaks.. Worn Seals or Gaskets: Over time, seals and gaskets in your compressor can deteriorate, leading to leaks. High Temperatures: Extreme operating temperatures can cause the oil to thin and leak through seals. [pdf]
