Button Bits manufacturers’ hydraulic drilling rigs are mainly used for underground coal mine drilling for gas extraction, drainage holes, grouting fire extinguishing holes, coal seam water injection holes, outburst pressure relief holes, geological exploration holes and other engineering holes. Its main application scope is as follows:　　1. In the general survey and exploration of...

What are the characteristics of triangular drill pipe products DTH Hammer adopts international advanced interference welding assembly technology to prevent quality risks caused by unavailability of friction welding technology. Compared with similar products, it greatly improves the mechanical properties of the product and the ability to adapt to deep hole drilling in complex geological...

　　 What is the reason that the oil temperature of DTH Hammer is too high? There are two parts to the overheating of the drilling machine: the oil temperature is too high; the water temperature is too high. Let's talk about these two situations together today. Let's take a look at it together. 　　 The hydraulic oil temperature of the crawler drilling rig is too high: 　　 First, let me talk about...

       The way to extend the use time of DTH Hammer is nothing more than correct operation and daily maintenance. Have you ever thought that there is a process from buying a pile driver to making money, in which equipment depreciation and personnel costs are not small expenses , If some human error operation leads to failure, maintenance is not a small expense....

Check DTH BitThe drill pipe is inspected using an instrument called a spherometer. Spherometer can check the radius of the sphere, which will let you know the degree of damage to the drill pipe. Once evaluated by the spherometer, the drill pipe must be classified into one of the three labels. N-level pipe: When a drill pipe is classified as n-level, it means that it is a new pipe. They are...

Fault oneThe hydraulic system of the drilling rig has insufficient pressure, and the pressure regulating valve is fatigued. Adjust the limit nut or replace the spring;If the pressure regulating valve seat cone is damaged or stuck, remove the pressure regulating valve sleeve for simple maintenance;Fault twoThe coupling of Top Hammer Drilling Tools becomes hot and the elastic ring is excessively...

　DTH Hammer The hydraulic walking pile frame of this machine is mainly composed of top pulley block, column, diagonal strut, chassis, running mechanism, slewing mechanism, hoisting mechanism, control room, hydraulic system and electrical system.   　　The column is a folding type, with a box-shaped cross-section structure and flange connection. The two sides of the column are equipped with...

     Top Hammer Drilling Tools is a positive displacement downhole power drilling tool that uses drilling fluid as power and converts fluid pressure energy into mechanical energy. When the mud pumped by the mud pump enters the motor through the bypass valve, a certain pressure difference is formed at the inlet and outlet of the motor, which pushes the rotor to rotate around...

      Top Hammer Drilling Tools is mainly composed of four major assemblies: bypass valve, hydraulic motor, cardan shaft and drive shaft. Screw motor is the main part of drilling tool. Many practical and theoretical analysis results show that if you want to make the motor normally and effectively When working, the pressure drop that each motor can withstand should...

         In the drilling work, the use of Rock Button Bits has been a great help, and do you know about hydraulic bolting rigs? Hydraulic bolting rigs have great performance in coal mines and drilling work, then hydraulic bolting rigs In the usual maintenance, do you carry out comprehensive maintenance for...
