Introduction
HFY2000 main drilling rig is ideal for the diamond and carbide core drilling, also can be utilised in engineering geological study, the EPT gap development, shallow oil, fuel and drinking water well drilling, and construction of big diameter basis undertaking.The EPT has a affordable framework, ligEPT excess weight, strong drilling functionality, stable overall performance, excellent reliability, and substantial stXiHu (West Lake) Dis.Hu (West Lake) Dis.rd and versaEPTty.
Principal Characteristics
1.Pick the EQ145 EPT clutch assembly , Substantial transfer torque. with diaphragm sort EPT clutch, substantial overload functionality.Adopt EQ153 clutch which outfitted
total pump and pump mix of EPT management system.Undertake the auto clutch EPT, steady overall performance, high safety element, the spare areas procurement is practical.
two.Coupling is utilized in the frequent drilling rig in EPT, which can easily create massive vibration and sounds, and the EPT EPT decline is up to thirty%.Now utilizing the most recent domestic merchandise quotwithin the tooth elastic coupling NL sort quot, the coupling are allowed a larger aXiHu (West Lake) Dis.al, radial and angular displacement, has easy structure, hassle-free maintenance, simple tear open outfit, minimal sounds, large effectiveness, EPT service lifestyle, massive EPT torque, and so forth.
3.The hoisting EPT breaks by way of the traditional 3 sets of planetary wheel system, and use four sets of planetary wheel system to supply large torque and very good steadiness.The hoist brake drum adopts the new composition, which has large EPT, small dress in and EPT services daily life.
four.Adopt the new water brake system.It is a mechanical device to change the descent velocity of the drilling tool when drilling down.The braking torque produced by its operation helps make the driving torque of the drill device on the reel be lowered, braking strength of the braking method is reduced, and the provider existence of the drill is prolonged.
five.Making use of the EPT sort EPT chuck, big clamping pressure, strong radial payment capacity .
six.This EPT is EPTn by electric powered motors or diesel engines, which can be used in accordance to user’s desire.
seven.It is equipped with sufficient devices to grasp the inside circumstance of the hole. In the meantime, equipped with enter and output tachometer to faXiHu (West Lake) Dis.Hu (West Lake) Dis.tate operation manage by operators.The handle deal with is considerably less, well laid-out, the management is fleXiHu (West Lake) Dis.ble and reliable.
8.EPT design EPT handle mechanism, aspect-shift operation, fleXiHu (West Lake) Dis.ble and convenient.
nine.The EPT EPT is ligEPT weight, compact structure, good detachable and simple to transfer.simple and realistic construction, all factors are uncovered, not overlapped, easy to keep and mend.
ten.The rig moved effortlessly and fastened firmly.powerful frame, lower cEPTr of gravity, higher steadiness and reliability when substantial velocity drilling.

How does rotary drilling operate?
Rotary drilling employs a rotating movement of a drill little bit in orEPTto produce use in the ground (in orEPTto drill into delicate groEPTor combined grouds):
– A rotary head, rotating many thanks to EPT motors, is put on a rig,
– a feed pressure is utilized to the string,
– The rotary head can make the drill string to rotate,
– At the bottom of the drill string there is a little bit, in get in touch with with the ground, the little bit EPTs the hole (the rotation of the bit generates wear).
– A fluid (water or drilling mud) is injected by way of the drill string till the bit. This fluid will flush the cutted material and carry them to the surface.
– As the little bit drills down, the rotary head goes down the rig. Then added rods are inserted in orEPTto go until the preferred depth.
For drilling in challenging rocks, rotary drilling is usually not the most tailored technic, for this it is much better to use a drifter (also known as difficult rock drill).
