QL80 DTH Hammer

 

QL80 DTH Hammer have been especially created for use in mining operations, It is the same quality as atlas copco. And they exhibit great penetration rates as well as long-lasting usable lives. Furthermore, it is suitable for drilling water wells, geothermal wells, and civil engineering wells.

The QL80 DTH Hammer with a foot valve is the most popular model of high air pressure DTH hammer. It is commonly used in well drilling, piling foundations, and engineering applications. LEANOMS has a great deal of expertise in producing High Quality QL80 DTH Hammer without Foot Valves.

 

QL80 DTH Hammer has the following advantages:

1. Prevent issues with foot valves. expansion, contraction, and fracture.

2. Less air is used, but there are more impacts each second. a bit with a foot valve has a drilling efficiency that is 15–30% lower.

3. Easier and less expensive maintenance due to simpler construction and fewer spare components.

4. heat treatment replacement parts have a longer lifespan and cause fewer issues.

5. Top sub and drive chuck thread connections facilitate disassembly.

 

 

The main raw materials of QL80 DTH hammer include:

1. Steel: Used to make hammer bodies and other important parts. Steel must be strong and tough enough to withstand high impacts and heavy loads.
2. Alloy steel: used to make impact heads. Alloy steel can provide higher strength and hardness to increase impact force and wear resistance.
3. Carbide: Used to make the cutting edge of the hammer head and the teeth on the hammer head. Tungsten carbide has extremely high hardness and wear resistance, which can keep sharp and durable in the process of breaking rocks.
4. Polymers: Used to make seals and other small parts. Polymers must have good chemical and abrasion resistance to maintain their performance under extreme operating conditions.
5. Lubricating oil: used to lubricate the hammer body and impact mechanism to reduce wear and friction. The lubricating oil must be stable under high temperature and pressure to ensure the long-term stability and reliability of the hammer.

 

 

 

The service life of the QL80 DTH hammer is affected by many factors：

 

Drill quality: The quality of the drill directly affects the service life of the hammer. If low quality drills are used, the hammer may wear out from being subjected to too much heavy load, resulting in damage. Therefore, using high-quality drilling tools can significantly extend the life of the QL80 DTH hammer.

Drilling Depth: Drilling depth is another factor that affects the life of the QL80 DTH hammer. In shallower hole depths, the life of the hammer is relatively long, while in deeper hole depths, the life of the hammer may be reduced. Therefore, if you need to drill deeper geological areas, you need to consider using a larger size drill bit.

Drilling material: The hardness and wear resistance of the drilling material also have an important impact on the service life of the QL80 DTH hammer. When drilling hard geological areas, drilling materials with higher wear resistance are required. This can significantly extend the life of the QL80 DTH hammer.

Drilling Speed: Drilling speed also affects the life of the QL80 DTH hammer. At too high a drilling speed, the hammer may wear out from being subjected to too much heavy load, resulting in damage. Therefore, it is necessary to select the appropriate drilling speed according to the geological conditions to prolong the service life of the hammer.

 

To sum up, the service life of the QL80 DTH hammer is affected by many factors. Drilling tool quality, drilling depth, drilling material and drilling speed are the most important factors affecting the life of the hammer, and their numerical forms are presented as follows:

 

1. Quality of drilling tools: Using high-quality drilling tools can extend the life of the hammer by more than 20%.
2. Drilling depth: When the hole depth exceeds 200 meters, the service life of the hammer will be shortened by about 30%.
3. Drilling material: Using high wear-resistant drilling material can extend the life of the hammer by more than 20%
