The application of high-end rock drilling equipment in China has gone through decades of history, from complete dependence on imports to domestic independent research and production, and then to widespread application in the rock drilling market. After years of hard research and development, the R&D and production personnel of Zhigao Company have successfully developed and produced a series of excavation trucks.

Analysis of the causes of faults in the operation of the screw air compressor system and corresponding solutions. Now, let's take a look at the content of the Zhigao screw air compressor from the editor of Hunan Ruisheng Mechanical and Electrical Equipment. The screw compressor is composed of a pair of parallel and mutually meshing female and male screws, and is the most widely used type in rotary compressors. There are two types of screw compressors: dry and wet

How to maintain a down-hole drilling truck? The editor of Hunan Ruisheng Mechanical and Electrical Equipment told you that the down-hole drilling truck should clean the oil mist and add lubricating oil in a timely manner. The down-hole drilling truck uses an impactor to achieve impact drilling, and good lubrication is a necessary condition to ensure the normal operation of the impactor. Compressed air is usually damp, and pipelines cannot be cleaned properly. After use, a certain amount of water and impurities are left at the bottom of the oil mist atomizer, which affects the lubrication and lifespan of the impactor. If it is found that the oil or oil contains moisture and impurities, it must be removed over time. When adding lubricant, to prevent injury, the entire intake valve must be closed first, and then the collision gas valve must be opened to remove residual gas from the pipe. Lubrication not allowed!

Nowadays, there are a wide variety of washing machines on the market, with varying prices. However, the quality of washing machines produced by different manufacturers varies. So what kind of washing machine do customers need to purchase? When purchasing a washing machine, remember the following points:

DTH drill truck is a semi hydraulic press truck, that is, except for the impact using compressed air, other functions are achieved through the hydraulic system, so the quality of hydraulic oil is crucial to the normal operation of the hydraulic system.

Working principle of screw air compressor: The compressed air system adopts a double screw air compressor. The operation of this machine is divided into three processes: intake, compression, and exhaust:

Correct maintenance and upkeep play a crucial role in the service life and operational reliability of screw air compressors.

Grinding knives does not harm the woodcutter. The inspection and preparation work before starting the diesel engine driven screw machine can timely detect potential faults in the machine equipment, avoid serious faults, and reduce the failure rate. Below are tips on the items that need to be inspected before starting the diesel driven screw machine

The reasons and solutions for the inability to open the intake valve of a screw air compressor. The intake valve of a screw air compressor is a component that controls the air pressure inside the air storage tank. Commonly used intake valves include a rotating disc structure and a reciprocating valve plate mechanism, which use a disc or valve plate to open or close the intake port and control the airflow entering the machine head.

How is the classification of down-the-hole drilling machines determined? There are several typical classification methods, and what are the corresponding types of each classification method? What are the similarities and differences between pneumatic, hydraulic, and fully hydraulic down-hole drills? The editor of Hunan Ruisheng Electromechanical told everyone the story of a down-hole drilling rig.

The working principle of the intake valve of a screw air compressor is that the intake valve is electrically loaded and closed. The current during device unloading may slightly increase, and the current during unloading at 22KW may be 31A. At first, it seemed that the intake valve was not closed. This is because if no gas is used, the pressure will slowly rise after the machine is unloaded, and the high pressure alarm may stop! In addition, even after the machine stops, there is still residual pressure in the machine that cannot be discharged (about 6 kg), causing the engine to overload during restart.

The working principle of a screw air compressor: The cylinder of the screw air compressor is equipped with a pair of meshing spiral male and female rotors, which rotate in opposite directions.

Generally, there are 7 kinds of drilling equipment as follows: conventional land drilling rig, desert drilling rig, truck mounted drilling rig, coiled tubing machine, inclined well drilling rig, offshore drilling platform and Drillship. A drilling rig is a complex set of machines composed of machines, units, and mechanisms. A drilling rig is a mechanical equipment used in exploration or development of mineral resources (including solid, liquid, gas, etc.) to drive drilling tools underground and obtain physical geological data. Also known as a drilling machine. A modern drilling rig must also have a set of auxiliary equipment, such as power supply, gas supply, water supply, oil supply and other equipment, equipment storage, anti blowout and fire prevention facilities, drilling fluid preparation, storage, processing facilities, and various instruments and automatic recording instruments.

Fog gun machine (other name: fog gun car) is a kind of machine whose spray system has a certain control effect on dust, reduces the content of large particles in the air, and has limited influence on small particles. The fog particles sprayed by the fog gun are very small, reaching the micron level. In haze weather, liquid mist can be reduced, the concentration of particles in the air can be decomposed, and pollutants and dust in the air can be effectively decomposed, thereby effectively reducing haze.

The exhaust temperature displayed on the air compressor panel is high, and it is necessary to first confirm whether the temperature sensor is displaying incorrectly. Portable infrared thermometer or thermal imaging can be used to assist in confirmation. Other reasons can be roughly divided into cooling system, lubrication system, equipment host and other system design parts, which can be confirmed separately.

In recent years, with the continuous strengthening of national environmental protection work, fog cannon machines have been recognized by many users due to their characteristics of "dust reduction, dust removal, and dust suppression". This not only facilitates the continuous promotion of environmental protection work by enterprises themselves, but also benefits the improvement of the sur...
