Introduction of safe operation of drilling machine in drilling work

At the automatic switch of the overhauled equipment, the brand of "overhauled and no moving" should be hung up, and personnel should be sent to monitor to avoid operation errors. However, when the pneumatic operation equipment is overhauled, it should be ensured that the air supply is reasonable. When necessary, the main air source pipeline should be removed to ensure safety. After that, after careful investigation and analysis by the safety accident investigation team, it was determined that the internal hydraulic seal of the gas relay, which is the normally closed use method of controlling the clutch of the transmission system, damaged the air blockage. When a certain working pressure is accumulated, the gas relay has its own effect, connecting the air source with the pneumatic tire channel of the clutch of the winch transmission system, and pushing the winch to rotate. Because there is no main air source (the air power switch is not closed), the winch will automatically terminate after only turning the driving force for two turns. After the on-the-spot experiment confirmed, the above reason is beyond doubt.

How to find a suitable drilling construction point for drilling machine

Looking for rock layers with good permeability and poor permeability grows and develops in rock fissures, and looking for water in mountainous areas with good permeability (lime powder areas). Due to the good permeability of rock layers, rainfall penetrates very deep along fissures, and the groundwater foundation is buried tens to hundreds of meters deep. At this stage, it is difficult to drill such deep wells in mountainous areas with scattered residential areas. To find water in such an area, one must make every effort to find superficial or relative aquifers. In that way, the aquifer can stop the groundwater that has penetrated into the upper end from seeping down again and accumulating on top of the aquifer. This type of fissure water, although sometimes the water flow is not large, but the buried shallow, small and medium-sized residential areas of tap water can meet the requirements.

Introduction to the advantages of truck-mounted drilling rig

Advantages of truck-mounted drilling rig: the slurry pump of truck-mounted drilling rig has extremely strong self-priming working ability, and can adjust the total flow rate of 10 levels to meet the production and manufacturing requirements; The truck-mounted drilling rig has good drilling tools and high weight, which can complete high-efficiency production and manufacturing with the help of its own weight working pressure during drilling. The strong hydraulic press of the truck-mounted drilling rig can alleviate the labor efficiency of the actual operation staff and save the actual operation staff; the truck-mounted drilling rig is equipped with four sets of hydraulic machine feet, and the telescopic length of different feet can be adjusted at will to integrate into different office environments.

Method of lubrication for drilling machine

Cleaning stains: In the push-type thin oil lubrication system software, the liquid oil continuously circulates the system to clean the surface, and the surface wear debris and victory can be removed during cleaning. The rotary speed reducer and the main reducer of the drilling machine are all oil bath speed reducers.

What are the working systems of vehicle-mounted drilling rigs?

The work of the truck-mounted drilling rig is huge, and the working conditions of each generator set and its characteristics are all different. According to the working characteristics of the drilling rig, we can divide the working system of the drilling rig into three parts. One is the rotating system, the improving system and the circulating system, and the complete drilling rig is composed of eight major system equipment. 1. Rotating system equipment and special tools. 2. Circulation system equipment and special tools. 3. Improve system equipment and special tools. 4. Drive force drive system equipment. 5. Transmission system equipment. 6. Control system and inspection digital display instrument. 7. Rig base. 8. Auxiliary equipment.

Introduction of maintenance skills of workover rig

Check whether the tension of the belt of the air pump is proper. Pay attention to observe the rubber pipeline of the gas path system to see if there is aging or cracking, and repair it in time. At the same time, we should also pay attention to the wiring, pipes and joints of the gas circuit system whether there is any leakage and looseness. Finally, I would like to remind you that if it is winter, you must remember to add a little alcohol to the antifreeze. Because the workover rig is a relatively complex equipment, it is very troublesome to repair once it fails, so routine maintenance operations must be done well. In addition to maintenance, it is also important whether the operators operate according to regulations.

Lubrication Mode and Function of Drilling Machine

Cooling and heat dissipation: In high-speed rotating parts, all heat is generated by friction. If the excess heat is not dissipated, the temperature will continue to rise, causing the parts to burn. For example, the oil cooling of the screw air compressor on the KQ-200 drilling rig acts as a heat sink.

Advantages and drilling methods of truck-mounted drilling rig

Reverse drilling method: In the production of this method, the truck-mounted drilling rig uses a ring drill bit with cemented carbide welded at the bottom to drill. When drilling, the truck-mounted drilling rig must apply a certain production pressure to ensure that the drill bit cuts into the rock and soil layer during drilling to achieve the most stable drilling intention;

Maintenance of drilling machine by drilling machine manufacturer

Finally, grease protection. The choice of lubricating oil (butter) can reduce the wear of the moving surface and avoid noise. Grease in storage and preservation, should not be mixed with dust, sand, water and other impurities; recommend the use of lithium-based grease G2-L1, good wear resistance, suitable for heavy load conditions; filling as far as possible the old oil all out, wipe clean, to avoid sticky sand.

How the drilling machine should be cleaned

Ensure that all kinds of parts are cleaned and cleaned. In the repair, all kinds of different parts are not the same. In the installation, the mating parts are higher than the non-mating parts. Should also be based on different repair processing technology to give their own cleaning, indeed. The quality of cleaning shall be guaranteed according to the specification. Avoid parts of the erosion, the high precision parts are not allowed to have all levels of erosion. When the parts need to be stopped for a period of time after cleaning, the anti-rust treatment ability of the cleaning fluid should be taken into account or other anti-rust treatment measures should be selected. To ensure the safety of operation, safety precautions shall be taken in common ways to avoid damage to operators, fire accidents or other unsafe risks.
