September 18, September 18, Don't Forget National Humiliation-Yikuang Technology
Looking back on the history, the September 18 Incident, also known as the Shenyang Incident, the Fengtian Incident, the Shengjing Incident, the Manchuria Incident, the Wicker Lake Incident, etc., was a military conflict and political incident that broke out in Northeast China on September 18, 1931. The two sides of the conflict were the Chinese Northeast Army and the Japanese Kwantung Army. The Japanese army occupied Shenyang under the pretext of the Chinese army blowing up the South Manchurian Railway built by Japan. After the outbreak of the incident, the contradiction between Japan and China intensified, while the status of the main war faction of the Japanese military department rose, and the power of the Prime Minister of the Diet and the cabinet declined, leading to Japan's full-scale invasion of China. Within a few years, all three northeastern provinces were occupied by the Japanese Kwantung Army. "9.18",

Water well drilling rig and drilling technology-beneficial mining technology.
Drilling is the use of mechanical equipment, in the formation of a certain attempt to drill holes in the project. According to the way of rock crushing and the type of drilling tools, it can be divided into drilling technology and rotary drilling technology. In geological exploration and geological engineering, it is beneficial for drilling equipment to drill underground. For cylindrical round holes with small diameter and large depth, it is called drilling. According to the drilling purpose, design different drilling straight and drilling depth. For example, drilling oil, natural gas and groundwater drilling diameter is larger. For geophysical logging core extraction and other general drilling is small. The main functions of drilling are: 1. Obtain underground physical data and obtain core from the bottom of the well.

What should be paid attention to when using drill tools-YiKuang Technology
(1) Before entering the rod, adjust the appropriate impact pressure, propulsion pressure, rotation speed and buffer pressure according to different geological strata, and debug the pressure values to match the geological strata and rock hardness between the pressure values. (2) When drilling, make the drilling tool group concentric to avoid bending deformation of the drill tail, drill rod and drill head. (3) Avoid empty hitting, stop drilling immediately when empty hitting occurs, and avoid causing excessive damage to drilling tools. (4) After the drilling of the drill rod is completed, each drill rod withdrawn should be coated with cooling lubricating oil in the thread end of the drill rod and the quick joint-after the drilling operation is completed, the thread connection of the drill rod is hot and

The relationship between drilling parameters and drilling effect-Yikuang Science and Technology
The relationship between drilling parameters and drilling effect impact pressure: the higher the pressure, the higher the piston speed and the greater the energy generated. When the drill bit is in good contact with the complete hard rock, the shock wave energy can be maximized. On the contrary, when the contact between the drill bit and the rock is not good, the energy cannot leave the drilling tool and be transmitted to the rock, but is reflected back to the drilling tool chain as a tension wave. Only when drilling holes in sufficiently hard rock can the maximum energy of each impact be used. In order to reduce energy reflection when drilling soft rock, the impact pressure or energy must be reduced. The greater any given impact pressure, the greater the stress in the drill pipe section. In order to make the drill rod, drill tail

Yikuang Technology analyzes the reasons for the loss of drilling tools for you.
Cause Analysis of Drill Loss (1) The non-concentric drill tail, connecting sleeve and drill pipe of the drill set cause bending deformation of the drill set and stress, resulting in non-cooperation at the joint of the drill set and loosening of the joint part. (2) The pushing pressure is too low, which reduces the penetration efficiency of rock drilling, causes the combination to loosen, causes the energy loss transmitted by the drilling tool group, causes great stress, and causes the instantaneous contact and separation of the contact joint end face. Insufficient pushing pressure is manifested by heating of the drilling tool, "clatter" at the joint, excessive heat causing excessive thread wear and corrosion pits. If the pressure is too high and the rotation speed of the drill bit is too low, there is danger of sticking, and the drill pipe is bent at the same time.

What should be paid attention to when using drill tools-YiKuang Technology
The drill rod is limited by the diameter of the drilling hole in the drilling and blasting project, and its cross-sectional area is very small. This slender rod should bear the cyclic stress of pulling, pressing, bending and twisting applied by the rock drill with high frequency and high impact under the condition of severe wear and corrosive medium. According to the different conditions such as load size and rock firmness, the rock drilling life is often only more than ten hours to more than one hundred hours. It is an engineering tool with the most demanding stress conditions, short service life, high technical content and huge consumption necessary for basic industries among all human mechanical tools. As every drill user wants to spend the least cost to get the most profit.

How to Maintain Drilling Equipment-Beneficial Mining Technology
General protective measures for high temperature, high humidity environment on the adverse effects of construction machinery, in order to reduce the downtime of construction machinery, play its maximum effectiveness, small make up two protective measures, as described below. 1. General protective measures (1) Strengthen on-site management In high temperature and high humidity environment, on-site management of construction machinery should focus on preventing rain, heat, moisture, sun and lightning strikes, and do the following work well: when improving the parking environment of machinery, when selecting temporary parking spaces, try to stay away from ravines, rivers and steep cliffs. To compact the ground foundation, dig the surrounding drainage ditch, handle the slope, clean up the surrounding weeds, eliminate snakes and mice, etc.
