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:Rotary drilling rig when piling, the drill bit off the hole in the pile, how to fish ah?
- If more than fifteen meters, a thin rope tied down with the steel wire rope is fixed on the pull. If you don't deep human, not safe, do a salvage device on the line, is a piece of steel, cut into type L, L below the horizontal slightly upwards with a point of view, with the top of the vertical wire rope L, you can then put on the bit.
- Q:What are the components of rotary drilling rig Jixietaiban? How to calculate?
- This contract according to the geology and site conditions have different changes, according to a 24 hour standard, a drill, a crane, a forklift, each driver two, a site manager, coolie four, perfusion six, a welder, purchasing a drill, water pump and other auxiliary vessel some general tools, according to the size of pile, geological conditions of pricing, how much money per meter.
- Q:How much do you charge for a day rig?
- You have to talk about it yourself, because the larger the rig, the higher the purchase price, the fewer people you buy. In addition, the rig is generally equipped with 2-3 manipulator, manipulator of the wages included in the rent, maintenance costs are also included in the rent and other low value consumable things such as drilling teeth, wire rope is not included in the rent, who who is responsible for the rent.
- Q:Long spiral applies to high-speed rail construction, civil construction, rotary excavation in relatively large diameter foundation construction, such as bridge foundation construction is more common.
- The basic difference between drilling technology of rotary drilling rig and reverse circulation drilling technology is that the former is to use the drill to remove the broken rock and soil directly from the hole, while the latter is to eliminate drilling slag by slurry circulation to the hole.
- Q:31 rotary drilling rig electromagnetic valve is what?
- The solenoid valve is used to drive the valve core to control the direction of compressed air, so as to control the direction of the pneumatic actuator switch.Its advantage is simple operation, easy to realize remote control.
- Q:What bucket teeth are used in rotary drilling machines?
- We use the site above alloy bucket tooth, tooth special rotary drilling rig alloy, durable many times more than ordinary tooth Oh, but the price is several times more expensive than ordinary, but together, but it is still very good, after all, little change in time, save a lot of trouble.
- Q:What material steel pipe do the drill pipe use?
- Commonly used materials for geological drill pipe are DZ40, DZ50, DZ60, R780 and other geological drilling seamless steel pipe. Seamless steel pipe for drilling pipe, which is used for petroleum drilling pipe in petroleum industry. General parameters of seamless steel pipe for drilling rod.
- Q:The relationship between rotary drilling and impact drilling and reverse circulation drilling
- Positive and negative cycle is another process, which is used to break the soil into small particles or mud, and the positive circulation is to use the pipeline to drill into the drilling site, and the orifice is discharged. Reverse circulation is drilling site pumping, orifice grouting. It can be used either as a roundabout or as an impact. Impact is the use of heavy hammer or DTH hammer broken soil, mostly mostly using positive cycle process.
- Q:How about the speed of rotary drilling rig?
- Not at all. It depends on how you do the work.
- Q:Price of small rotary drilling rig
- Tengzhou Kai Ao Construction Machinery Co., Ltd. small rotary drilling rig, piling depth between 1-40 meters, the pile mouth diameter range is 0.2-2.2 meters, the price is: 13.5-68 million between
