DTH Hammer is widely used in all kinds of hard and abrasive rocks,suitable for following features: 1.New products designed based on mining condition in China, improving by advanced technology from global market. 2.Superior materials, advanced progress, guaranteed quality. 3.Faster drilling rate, can drill around 25~30 meters per hour on hard rocks. 4.Hardness can be enhanced to expand the lifespan of hammer, and lower the cost. 5.Huge impulse with low consumption of electricity. 6.The modern theory is adopted in the structural design, which makes the stress. 7.Wave duration longer, the stress amplitude is lower, and the piston life is lon...

In order to achieve high perforation efficiency, drilling rigs equipped with high-pressure air compressors have gradually taken the mainstream. The drilling efficiency of a drilling rig is critical. Because the perforation efficiency of the drilling rig mainly depends on the down-the-hole hammer, the air consumption of the hammer is determined by its design structure. With the increase of wind pressure and air volume, the output power of the hammer doubles, and the drilling speed also doubles. improve. That is to say, when a high-performance drilling rig and a high-efficiency hammer are selected, there must be an air compressor with corre...

Truck Mounted Type Water Well drilling rig machine The truck-mounted drilling rig is specially designed for field drilling and convenient transportation. The vehicle-mounted type integrates the truck chassis, drilling rig equipment, air compressor, mud pump, etc. The structure is reasonable and the operation is simple. After arriving at the construction site, there is no need for additional crane loading and unloading, which greatly facilitates the drilling work and saves manpower and material resources. 1. The truck chassis can be selected from Chinese brands such as Sinotruk and Dongfeng, or other brands can be selected according to cus...

What rules should be followed during the Drilling process ? 1. Comply with the computer procedures and safety inspection procedures (1) Understand water well drilling rigs, action rules, safety protection regulations, and understand the performance and specifications of water well drilling rigs. 1. Know the rules (1) Do not carry people on the machine. (2) Understand the performance and operating characteristics of the machine. (3) When operating the water well drilling rig, do not let irrelevant personnel approach, and do not modify or dismantle any parts of the machine (unless it is needed for maintenance). (4) Keep bystanders or unrela...

Down-the-hole drilling rigs can drill holes in rocks of medium hard or above (f≥8). Like the rock drill, it has the process of impacting, rotating, discharging and advancing the rock drilling hole. The difference is the impact mechanism of the down-the-hole drilling rig. The extension and continuous advancement. The down-the-hole drill is named after the impactor dives into the hole, and has the following advantages in use: 1. There is no energy transmission loss, the impactor directly acts on the drill bit, no drill pipe is required to transmit impact energy, and the drilling speed is not affected by the depth of the hole. 2. The hole is...

At present, whether in domestic construction or overseas contracting of water well projects, roller cone drilling technology is generally used, especially for deep water wells and geothermal wells. Judging from the field of roller bit use in recent years, it has been extended to pile foundation construction, trenchless engineering construction, and coal mine gas drainage well construction. The scope of application is continuously expanding, and the social and economic benefits produced are very significant. Engineering practice has proved that the use of roller bit drilling technology has no special requirements on the formation and groun...

The starter is generally composed of three parts: a DC motor, a transmission mechanism and an electromagnetic operating mechanism. The correct use and maintenance methods of the starter, in order to extend the life of the starter, and ensure that it can work quickly, reliably, and safely, the correct use and maintenance requirements for the starter of the water well drilling rig are as follows: 1. The starter is designed for short-time high-current operation, and its output power is also the maximum power. Therefore, when using the starter, the working time should not exceed 5 seconds each time, and the repeated start must be separated by...

Introduction of the Drill Rods Seamless alloy steel pipes are made into drill pipes after several processing steps. First of all, through the processing of the steel pipe thickening process, the outer surface of the light pipe is bent inward, and the wall of the steel pipe is thickened. The next step is threading and plating with copper for strength. A non-destructive quality control inspection is then carried out, followed by welding of the steel pipe body joint. Then, the tube undergoes a welding heat treatment and a welding finish to eliminate welding residual stress. Several other tests are performed on the finished steel pipe before ...

How to Maintain the water well drilling rig during the run-in period. 1. Pay attention to the working load during the running-in period. Generally, the working load during the running-in period should not exceed 80% of the rated working load, and a suitable workload should be arranged to prevent the occurrence of overheating caused by long-term continuous operation of the machine. 2. Keep the machine clean, adjust and tighten loose parts in time to prevent the loose parts from aggravating the wear of the parts or causing the parts to be lost. 3. Pay attention to frequently check the lubricating oil, hydraulic oil, coolant, brake fluid and...
