HZ Series Hydraulic Core Drilling Rigs

2022.05.24

HZ Series Hydraulic Core Drilling Rigs The HZ series hydraulic core drilling rig is a portable drilling rig, also have a wide range of uses. It is suitable for geological survey of railways, water conservancy, bridges, dam foundations and other buildings, geological core drilling, small grouting holes, blasting holes, and water well drilling. Diamond drill bits, PDC drill bit and alloys drill bit can be used for drilling according to different formations. 1. With hydraulic automatic feed mechanism, it can improve drilling efficiency and reduce the labor intensity. 2. The ball clamp clamping mechanism is used to instead of the chuck, whic...

Water Well Drilling Machine Routine Maintenance

2022.05.16

Water Well Drilling Machine Routine Maintenance 1. Check the pulley system of the drilling rig at any time; 2. Regularly inspect various power heads, oil cylinders, drill bits and drill rods; 3. Check the oil circuit, hydraulic pressure and walking system of the drilling rig; 4. Regularly inspect the wire rope of the hoist; 5. Make rig maintenance records and replace spare parts; 6. If the drilling rig is found to be faulty, the operation should be stopped immediately, and it must not be used until the fault is eliminated.

The Advantages of the Pneumatic Drilling compare to Water Drilling

2022.05.11

1) The single impact power of a pneumatic drill is large, generally up to tens of kilograms or more than a hundred kilograms, which is more than ten times-dozens of times the single impact energy of the current hydraulic impactor. Therefore, from the perspective of rock crushing, the gas drill is mainly based on impact crushing rock, and the rotation only changes the location of impact crushed rock, and at the same time plays the role of auxiliary rock crushing. Therefore, the drilling efficiency depends to a large extent on the performance and quality of the down-the-hole hammer. (2) Due to the low air density during gas drilling, the pr...

Tractor Type Water Well Drilling Rigs

2022.04.23

The tractor type drilling rig is a fully hydraulic power head drilling machine. With four-wheel drive, it has good off-road performance and is suitable for drilling in various working conditions. The drilling rig adopts a full hydraulic driving system, with simple structure and easy operation, also a large power engine from the tractor. It can be widely used in drilling work such as geological exploration, water wells, and slope support. The machine consists of seven parts: tractor chassis, power head, telescopic mast, operating table, hydraulic oil tank, mud pump, drilling tools. It can not only drilling by mud pump, but also connect a c...

Why the DTH Blasting Drilling need a Dust Collector system ?

2022.04.18

When the down-the-hole drilling rig operating, it is powered by compressed air. With the increase of air pressure, the drilling speed of the down-the-hole drilling rig is faster; with the increase of dust at the drill pipe, dust is spread around the drilling rig. It will not only endanger the health of operators, but also affect the speed of down-the-hole drilling operations and accelerate the damage to mechanical and electrical equipment. If no effective dust removal measures are taken, it will cause great dust pollution to the mine environment. For operators who work in high-concentration dust environments for a long time, if the protec...

Rotary Drilling

2022.04.08

Rotary drilling is currently the most commonly used drilling method, divided into two methods: positive circulation drilling and reverse circulation drilling. The rotary drilling method is to drive the drilling tool to rotate through the rotary mechanism. The drill bit installed at the end of the drilling tool cuts the soil or grinds the rock for drilling. The flushing medium (water, drilling flushing fluid) is injected into the drill at a certain flow rate and pressure by a high-pressure water pump. Tool to drain the muck from the hole to form a hole. According to the power transmission mode, rotary water well drilling rigs can be divided...

How select drill bits for different working formations of drilling rigs?

2022.04.07

The drill bit is one of the important drilling tools in the drilling of water well drilling rigs. It can be said that without the drill bit, the water well drilling rig equipment cannot be started and produced normally. This shows the importance of the drill bit in the water well drilling rig. For different types of water well drilling rig equipment, different drill bits are required in production. When selecting drill bits for water well drilling rig equipment, the following aspects should be paid attention to: 1. When producing in soft rock with better drillability, the drilling speed is faster, and it is necessary to choose the one wit...

Root canal drill introduction on water well drilling rig

2022.03.18

Root canal drills are different from straight-line drills. The canal drills are mainly used for hard, loose, broken or pebbles. It is necessary to follow up the drilling of the stratum of the casing at the same time, which has the advantages of good wall protection performance and high drilling efficiency. The working principle of root canal drill: 1. At the beginning of rock drilling, the eccentric reaming sleeve is unscrewed along the center guide bit, and reaming is started at the same time to ensure that the casing and the drilling system advance at the same time. 2. After the follower pipe is drilled in place, carefully reverse the d...

Fatigue and failure of drill pipe

2022.03.16

Vibration, bending wear When the drill pipe reaches critical speeds, the drill pipe vibrates, often resulting in bending, excessive wear, rapid damage and fatigue damage. Tensile failure Tension failure usually occurs when pulling stuck drill pipe. When the tensile force exceeds the yield point, “neck” deformation occurs in the thinnest local or smallest cross-section of the drill pipe wall. If the lifting force exceeds the previous limit strength, the drill pipe will be broken. Tensile damage usually occurs in the upper part of the drill pipe. Fatigue and damage Fatigue damage is the most common type of drill pipe damag...
