Benefits & Features
1.Efficient Rock Breaking
The maximum hardness of rock which can be cut at time of joint development is f11;
We can design, process and manufacture cutting teeth on our own to eliminate the need for import;
Three-stage vibration damping technique: patented cutting teeth arrangement, flexible transmission and differential pressure damping structure are used to systematically solve the problem of impact damage by cutting vibration on the overall machine and critical and important parts.
2.Efficient Dust Removal
Integrated dust removal system innovated in the industry: long-pressure short air ventilation curtain type dust removal system with a total dust removal efficiency of ≥97%.
On-board mining-purpose dust-proof suction system: fundamentally solve the problem of harm to health of staff by construction dust and powder.
3.Centralized Lubrication
The roadheader employs centralized lubrication technique so that lubrication is easy greatly saving oil injection time and reducing work load of underground workers.
- Q: Why is the rotary drilling rig put into the steel cage before pouring?
- When pouring concrete to the reinforcement cage, if this time to improve the catheter, catheter at the bottom of the reinforcement cage distance is only about 1m distance, due to pouring concrete pipe after homing large impact force, promote the rebar cage floating;
- Q: Tire type rotary drilling rig, drilling depth of 15 meters, diameter 1.2. This machine is how much money.
- I have been to the factory, and I can not say it is a lie. The equipment may be used in local geological conditions.
- Q: What's the minimum cost of a rotary drill? How much is it?
- Sunward rotary drilling rig 22 models and 25 models of new machines, 22 of the 5 million or so. 25 will be around 6 million, depending on your choice of accessories
- Q: How many litres of oil are usually consumed per hour in a rotary drilling rig?
- This depends on what kind of model, different models of engine power is not the same
- Q: Is there a need to calculate the construction and transport of the mud pit separately in the budget of the pile driving pile?
- Rotary drilling rig is the first barrel type rotary drill through the bottom valve with broken rock and soil, and directly in the drilling bucket, and then by the rig hoisting device and drill rod of the drilling bucket dumping hole is proposed, so the cycle, constantly borrow dump, until the drill to the design depth. For the good cohesive rock soil layer, dry or clear water drilling technology can be adopted, without mud wall protection. For loose and easy to collapse formations, or groundwater distribution, unstable wall, it is necessary to use static mud wall drilling technology, and put in protective wall slurry or stabilizing liquid into the hole.
- Q: Is the rotary drilling rig driven by electricity?
- Of course, this is just a simple statement. It's very complicated. So. The driving force of rotary drilling rig is the internal combustion engine of diesel oil. The internal combustion engine then drives the hydraulic main pump.
- Q: How can we not drill the rod and drill the rod?
- Resolvent：1. Remove the drill pipe and remove the foreign objects.2, repair wear and deformation parts.3, open the drill rod, plastic alignment.4, adjust the operation method.
- Q: What bucket teeth are used in rotary drilling machines?
- Rotary drilling machine selection bucket teeth must select special rotary drilling machine bucket teeth, after all, in the ground tens of meters, can not be like excavators, to spin wear-resistant
- Q: Which rotary drilling rig is durable and economical?
- With FR622D FR620D, leiwo, comfortable operation, strong ability in rock.
- Q: The best domestic rotary drilling rig, steel wire rope manufacturer
- Therefore, it is necessary to have good flexibility, good abrasion resistance, good rotation resistance and good resistance to extrusion. Especially for the front of multi layer winding
