DTH Drill Pipe uses an impactor and a drill bit that are submerged into the bottom of the hole to impact and crush the rock, so it is called a down-the-hole drill. It is widely used in metal mines, hydropower, transportation, building materials, harbors and national defense projects. Down-the-hole drilling rigs can drill holes in rocks of...

Reaming Bit is easy to cause metal material contamination to enter the hole when working for the pilot hole. Therefore, when the raise rig is working, special personnel should be assigned to remove the slag to avoid the accumulation of slag in the hole and cause the above impact. When installing a new gasoline pump, motor, or disassembling or replacing the gasoline pump or internal parts of...

When working in different rock formations, choose different types of Extension Drilling Tools, axial pressure and speed according to the hardness of the lithology.2. When drilling rigs, they must follow the principle of matching the three elements of the drilling (wind pressure, axial pressure, and speed) with the parameters recommended by the drill bit sample.3. Before going down the well,...

　　 Repeatedly lifting drill refers to passing the stuck point through repeated lifting, lowering, and lifting operations at the stuck position. After determining the stuck position of the drill bit of the DTH Bit, by controlling the lifting system of the rig, a series of irregular and frequent repeated operations such as raising, lowering, and slow turning are adopted. This kind of operation...

 1. Skilled rock drill operators can well adjust the working status of rock drilling equipment during eye opening and rock drilling. For example, when opening the eye, the air volume should be lowered, and low impact force, slow propulsion, low speed, etc. should be used to avoid damage to the drill bit caused by the high stress of the cemented carbide sheet under the bending state of the...

    Everyone knows that no matter what machinery you need to clean, maintain and maintain, if it is not maintained, various parts of the DTH Bit may be damaged, and the DTH Hammer cannot be used, so we must pay attention to the DTH Hammer The maintenance and maintenance of the DTH Hammer, but if we do not pay attention to the maintenance in our usual work, it may cause some...

Ways to improve the service life of DTH Hammer:For the problem that affects the service life of the drill bit, the following solutions can be adopted: a. Because the titanium alloy has large elastic deformation and the hole is easy to shrink, the drill tip is slightly sharpened to appropriately increase the expansion of the hole. b. Increase the main cutting The clearance angle of the blade and...

There are many ways to classify DTH Bit, the most common ones are as follows:　　 1. Classification by purpose　　 Engineering drills are mainly used in construction and construction. There are many specifications of this kind of engineering drills, and the amount is large, and a special main product series has been formed　　Industrial drills are mainly used for drilling and coring. They are mainly...

　　I believe that many customers and friends will encounter the DTH Bit installed and the air valve opened, and only the exhaust sound of DTH Bit peeing...but there is no impact. 　　 You should stop at this time, take it apart patiently, check the inside of the DTH Bit carefully, and don't perform brutal operations. 　　 That is generally checked from the following aspects: ...

Tapered Button Bits is a special kind of drill bit, which is suitable for many rock layers or a kind of practical tools needed when drilling rock products. Because of its hard texture, it is used in various types of processing enterprises. Both of them are very practical, and this kind of Tapered Button Bits has one of the biggest characteristics, that is, the round holes he punched out of...
