Market development overview, from the perspective of pneumatic rock drill products, in recent years, the market has become saturated, the domestic product market share is more than 90%, basically resisted the import of foreign brand products, and a certain batch of products exported to developing countries, its overall quality has reached the international level, has become a banner of China's national industry. 　　

　The essence of downhole drilling is to submerge the impactor into the hole during the drilling process to reduce the energy loss caused by the impact work transmitted by the drill pipe, thereby reducing the influence of hole depth on the drilling efficiency. The drilling equipment for downhole drilling is a downhole drilling rig, and the downhole drilling rig is an impact rotary drilling rig. Its internal structure is different from that of ordinary rock drills. Its gas distribution and piston reciprocating mechanism are independent, that is, the impactor. The front end is connected directly to the drill bit and the rear end is connected to the drill pipe. When drilling, the impactor pierces into the hole, and the piston (hammer) in the impactor reciprocates, hits the drill tail through the gas distribution device (valve), so that the drill bit hits the rock at the bottom of the hole. 　　

The high-speed rotation of the impactor in the hole is achieved by a separate rotation mechanism by a drill pipe connected to the rear end of the impactor, that is, an electric motor or pneumatic rotation device outside the hole. The rock powder produced during rock drilling is washed out of the hole by the feng shui mixed gas, and the mixed gas is injected into the impactor through the center of the drill pipe by the powder discharge mechanism, and then enters the bottom of the hole through the air groove on the impactor cylinder block. 　　

What is the correct use of DTH drilling truck in drilling procedures and unloading rods, follow the editor of Hunan Ruisheng Electromechanical Equipment to take a look. 　　

　　DTH drilling truck during use we need to maintain it well, in addition to regularly check the hydraulic oil, regularly clean the oil tank and oil filter, what else do we need to do to maintain their own DTH drilling truck, follow Hunan Ruisheng mechanical and electrical equipment Xiaobian to take a look. 　　

At present, the development of environmental protection industry continues to improve the requirements for environmental protection. The important reason is that the current environmental pollution is too serious. The use of dust removal equipment has greatly alleviated the current environmental pollution pressure, and the pollutants emitted by industrial production have reached the standard. In China, the vacuum cleaner equipment industry is an important sub-industry of the environmental protection industry.

When drilling, the hole is first drilled with impact energy, thrust and low speed to facilitate drill bit positioning. Drilling about 10 cm affects the entire throttle and appropriately increases propulsion. Increase speed, perform conventional rock drilling, drill the drill pipe to stop the wind turbine operation, stop the air supply to the impactor, insert the fork into the drill pipe groove of the rig, reverse the motor and slide it back, cut the joint from the drill pipe, and drill out the second drill pipe for continuous operation. 　　

The pressure regulating mechanism completes the section of the propulsion force to complete the drilling work efficiently, the lifting and amplitude adjustment of the drilling rig is completed by the mechanism, and various actions are controlled by the control mechanism. The supporting mechanism can be a bracket or a drilling rig. Rock chips (powder) formed during drilling. The gas or water flowing through the drill pipe and the hole wall is carried out of the hole. The DTH drilling rig does not have the same ability loss as the rod drilling of the duck rock machine, because its drilling stalk does not transmit impact energy, so the impact energy loss is small, so deeper holes can be drilled. Since the impactor works deep into the hole, the noise of the working face is greatly reduced and the drilling accuracy is high. Drilling rigs are widely used in metallurgy, mining, building materials, railway, hydropower construction, national defense construction and earthwork and other open-pit projects of blast hole drilling and underwater drilling blasting reef engineering.

　Features of engineering wheel washer: computer software control, can automatically complete the work of rinsing, mud draining, rinsing water can be recycled, continuous work, only a small amount of water needs to be replenished, so it can save a lot of water resources. It is especially suitable for all kinds of construction sites, mining workshops, cement product factories, coal mines, power plants, landfills and high-end neighborhoods to clean the interior and exterior of vehicles. This ensures excellent engineering without causing dust pollution.

What do we need to know about the precautions and daily maintenance of the work of the drilling rig? Now the small editor of Hunan Ruisheng Electromechanical equipment takes you to understand that the following is the precautions for the work of the drilling rig

Regularly check the hydraulic oil, the DTH drilling truck belongs to the semi-hydraulic car, that is, in addition to the impact of compressed air, the rest of the functions are achieved through the hydraulic system, so the quality of the hydraulic oil is very important for the normal operation of the hydraulic system. 　　

　　The construction site should improve the washing facilities for entering and exiting vehicles to ensure that the vehicles are rinsed when they go out. Automatic vehicle flushing devices should be set up at the entrances and exits of the newly started construction site, and a water pool should be set up on the road in the site, equipped with high-pressure flushing water guns. The construction unit shall arrange a special person to be responsible for the washing of incoming and outgoing vehicles and the cleaning of the surrounding roads, ensuring that the outgoing vehicles are washed for no less than 3 minutes, and the wheels and body are not on the road with mud; Responsible for the "three packs in front of the door", regularly clean the mud around the flushing device and the sedimentation tank, and clean the surrounding area of the gate in time to ensure that there are no obvious mud marks or scattered sand and gravel on the road surface of the vehicle exit. 　　

What are the maintenance methods and precautions for a down-hole drilling truck? Installation of the unit: Prepare a rock drilling space, and the size of the space can be determined based on the model and method used for drilling. Introduce air and water pipelines, lighting lines, etc. near the working point for use. According to the requirements of hole design, ensure the reliable positioning of the drilling rig.

　Usually, many people see a wheel washer (car washer) at the construction site, but this is an important way to remove dust from the construction site. Cleaning turbines on site doesn't stop there. Let's take a look at the main points to ensure high reliability of on-site cleaning turbines.
