What is a core drilling rig?

 Core drilling rigs are deep hole drilling equipment for geological prospecting, hydrological water wells, coalfield geological exploration, oil, and natural gas exploration and development. The drilling rig combines the advantages of vertical shaft hydraulic drilling rigs. It can perform diamond drilling with small diameters, large diameters, vertical drilling, and inclined holes. It is ideal equipment for deep-hole geological exploration drilling.


Core drilling machine for sale scope of application

  1. Engineering geological survey of railway, hydropower, transportation, bridge, dam foundation, and other buildings.
  2. Geological core drilling, physical survey.
  3. Drilling of small grouting holes and blasting holes.
  4. Drilling of small water wells.

Features of core drilling rig:

  1. Equipped with a hydraulic automatic feeding mechanism to improve drilling efficiency and reduce the labor intensity of workers.
  2. The ball clamp clamping mechanism is used instead of the chuck, and it is equipped with a clamping positioning mechanism to realize the non-stop inverting rod.
  3. Equipped with a pressure gauge at the bottom of the hole to indicate the pressure, which is easy to grasp the situation in the hole.
  4. The handle is centralized and easy to operate.
  5. Compact structure, the drilling rig, and power machines are installed on the same base, occupying a small area.
  6. Lightweight, strong decomposability, easy to move, suitable for working in plains or mountainous areas.
  7. Equipped with a safety shield, highlighting the humanized design features of the equipment.
  8. A fixed nut is installed at the connection between the lower end of the feed cylinder and the vertical shaft box, which improves the reliability of the drilling rig.

The rated drilling depth of the core drilling rig is 200m, and the depth shall not exceed 220m. The rated opening diameter is 200mm. A large opening diameter allows 300mm. The drilling depth and drilling diameter should be determined according to the formation conditions.

What is the difference between a shot blasting machine and sand blasting machine?

Image
  Shot blasting machine is generally used for regular shapes, etc., several blasting heads are up and down, left and right, high efficiency and low pollution. In the shipbuilding industry, shot blasting and sand blasting machines are commonly used. However, both the shot blasting machine and the sand blasting machine uses compressed air. Of course, it is not the floor shot blasting machine that has to use a high-speed rotating impeller. In shipbuilding and shipbuilding industries, floor shot blasters are generally used for steel plate pretreatment (removal of rust before painting); shot blasting equipment (ores used in repairing and shipbuilding industries) are mostly used for shaped ships or sub-parts. The function is to remove the old paint and rust on the steel plate and repaint it. In the shipbuilding and shipbuilding industry, the main function of shot blasting equipment and automatic sandblasting machine is to increase the adhesion of steel plate coating paint. In fact, t...

  water well drilling rigs Water well drilling rigs are easy to move, small in size, and high in work efficiency. They are fully hydraulically controlled for lifting, outriggers, lifting, and other processes. Drill pipes can be replaced without stopping the machine. It can meet various geological conditions such as soil, well-drilling sand, and rock pebble layers. Structure, equipped with high-power hydraulic motor, high torque, fast drilling speed. Water well drilling machine is suitable for complex formations such as soil layer, rock layer, pebble layer, cemented pebble layer, etc. Water well drilling rigs are widely used in foundation engineering construction of high-rise buildings, large bridge projects, water conservancy construction, farmland engineering, and other fields. Small water well drilling rigs are suitable for building pile foundations, high-tension line tower pile foundations, dam foundation drilling, drilling water wells, agricultural irrigation wells, and engin...

How to choose a wet wipe packaging machine?

Image
 The packaging is a necessary condition for products to enter the cycle, and the main means to achieve packaging is to use packaging machinery. With the development of the times and the advancement of technology, packaging machinery is becoming more and more important in the packaging field. With the continuous progress of the economic era, people's quality of life is also continuously improved, and enterprises are also facing various risks and challenges. Therefore, continuous progress and innovation must be adopted in all aspects of work, especially in product packaging is also very important. So how to choose a wet wipe packaging machine? The selection of the wet wipe packaging machine can be based on the permitted production, packaging speed, packaging weight, packaging size, and determined packaging. The length of the product and the analysis of its ingredients determine how many packages per minute can be achieved at the highest packaging design speed. The machine rolls and...
