What is a pneumatic bar and where it is used?

The development of the technological process contributes to the fact that many works are performed easier and faster. If necessary, making drilling well Many masters are asked about which tool in this case is better to use. According to experts and consumers, for such tasks, a pneumatic room is suitable.

Features, pros and cons

The pneumatic replacement is called the drilling tool of a pneumatic type, which works on the basis of shock or shock-rotational mechanisms. The basis of its operation may be an open or underground method. This type of equipment is used when working with strong, abrasive and destroyed rocks. It is part of a large drill.

This drilling tool is often used during geological exploration drilling, exquising procedures. When working with equipment, you can get a well, the diameter of which is 8.5-25 cm, in some cases – 80 cm. The depth of drilling in this case can be from 30 to 80 meters.

The above indicators may vary depending on the quality of the breed, impact energy and rotation speed.

The drilling tool is characterized by the following advantages:

  • reliability, long service life;
  • the efficiency of cleaning from the sludge;
  • ease of use;
  • the possibility of fast and easy tool replacement;
  • lack of jamming tool while working.

Minuses at the pneumatic bar also have, one of them is considered the need for a large number of compressed air for work. Besides Masters during the use of drilling instruments have to ensure the stability of the walls of the wells.

Principle of operation

Pneumonian is a cylindrical type of device, inside of which the piston is located. Consider the principle of operation of this equipment.

  1. Air in a compressed form is sent to special swivel chambers and a boom column. Due to the difference in working pressure in the pneumatic system, the movements of the return and progressive type in the piston arise. The latter has a rod that has an impact on a rocking tool.
  2. Under the influence of high pressure, air through the adapter is output due to the hole in the crown. Such an action entails the destruction of rocks, as well as the rise of the sludge.
  3. On the passage speed influence the increase or decrease in air pressure, as well as the energy of single blows.

Types

Well drilling tool can have different diameters.

The greater this indicator, the higher the performance of the submersible pneumatic.

Currently on the market you can meet two types of this tool.

  1. Exploration, which is used to drill wells that in diameter do not exceed 25 cm.
  2. Annular. This type of equipment is perfectly coping with solid breed drilling. In order to protect the pneumatic plant from the impact of negative environmental factors, the tool is covered with tungsten or carbide.

According to the distribution of air allocate certain types of equipment for drilling wells.

  1. Valve. In the low-pressure tool there is a plate valve, due to which the airflow is adjusted.
  2. Inflicted. Pneumatic piston operating with profile pistons that regulate air pressure. This model of equipment is considered modern and improved. Blipping equipment functions on water mixtures or exclusively on air.

According to a connection with crowns, pneumatic-boring plants are divided into two types.

  1. With a slotted compound. Pneuma Pneuma provides high quality centering crown. Due to this, the accuracy of drilling increases, and the procedure for cautioning is simplified.
  2. With bayonet compound. A tool with straight washing and without it is characterized by the reliability of docking and speed of replacement.

Manufacturers

When choosing a pneumatic plant of Chinese or domestic production, it is worth considering its structural and functional features. Besides, The consumer should draw attention to energy savings by the unit, as well as its air flow. The model and brand of the tool for drilling wells is chosen according to the buyer’s preferences.

The most popular models include the following:

  • Sandvik;
  • Robit;
  • Irev Series;
  • Segovia;
  • Everdigm;
  • Haus Herr;
  • Wolf.

The selected pneumatic bar must fully comply with the tasks set before him.

There are also tools for heavy working conditions, they have a large outer diameter. Equipment for deep wells designed specifically for high performance processes. Such aggregate models are particularly relevant for large volumes of groundwater and deep wells.

Care

In order to increase the service life of the pneumatic bar, as well as to prevent emergency situations when using it, the user should correctly care for the tool. Before installing either dismantle the equipment, it turns it over and check the freedom of movement of the inner piston. In this case, the movement must be accompanied by deaf sounds.

The use of an aggregate for drilling wells must be accompanied by its lubricant, namely by adding fine oil into air filing. Some masters make some oil in a drill string during the installation of the rod.

Most often, the pneumatic bar breaks down due to clogging, piston wear.

To resolve the problem, you will need to go through the equipment, dismounting it in advance.
