Accessories for water well drilling rigs that require regular maintenance

If any part of the full hydraulic water well drilling rig is found to be abnormal, should it be diagnosed immediately and remedial measures should be taken? Today we meet to see the need for regular maintenance. Maintenance of the filter element: The filter element is used as a filter to filter out impurities in the oil circuit or gas circuit to prevent entry into the system and cause failure. Operation and maintenance manuals. If metal particles are found to adhere to the old filter element, please diagnose immediately, take corrective measures, and use a pure filter element that meets the machine specifications. It is certain that the theoretical analysis results are in good agreement with the actual drilling results. Secondly, azimuth and small formation slope, formation position force, front angle, formation pressure, formation dip, normal cutting anisotropy index of full hydraulic water well drilling rig, formation anisotropy index, borehole direction and formation change direction, or possible direction decrease. Under normal conditions, when the well is formed, the drill bit of the full hydraulic water well drilling rig is close to the normal direction of the formation, and the azimuth angle of the formation changes the direction of the well to the formation. The formation deformation force is zero if the full hydraulic water well rig well direction matches the azimuthal direction of the formation.

The problems that should be paid attention to in the truck-mounted drilling rig

The running-in period is the main link to ensure the normal operation of the pile driver, reduce the failure rate and extend its service life. However, at present, some users neglect the special skill request during the running-in period of the new machine due to the lack of common sense of using the loaded highway pile driver or due to the tight schedule or the desire to obtain income as soon as possible. Some vehicle-mounted drilling rig users even think that the manufacturer has a warranty period anyway, and the manufacturer is responsible for the maintenance of the vehicle-mounted drilling rig machine if it breaks down. As a result, the machine will be overloaded for a long time during the running-in period, resulting in frequent early failures of the vehicle-mounted drilling rig machine. This not only affects the normal application of the machine, shortens the service life of the machine, but also affects the project progress due to the damage of the machine. Therefore, the use and maintenance of the mechanical running-in period should cause adequate respect. 1. The vehicle-mounted drilling rig wears fast Due to the influence of the processing, assembly and adjustment of new machine parts, the friction surface is rough, the contact area of the mating surface is small, and the pressure-bearing state of the surface is uneven. In the running process of the machine, the concave and convex parts of the surface of the parts are fitted and rubbed with each other, and the parts are damaged and the early failure occurs. 2. Poor lubrication of truck-mounted drilling rig Due to the small fit clearance of the newly assembled parts of the truck-mounted drilling rig, and due to assembly and other reasons, it is difficult to ensure the uniformity of the fit clearance. Lubricating oil (grease) is not easy to form a uniform oil film on the friction surface to prohibit wear. Thereby decreasing the lubrication efficiency, resulting in early abnormal wear of the machine parts. In severe cases, it will cause the friction surface of the precise fit to scratch or bite, resulting in failure. 3. Looseness of truck-mounted drilling rig The newly processed and assembled parts have deviations in geometric shape and matching dimensions. In the early stage of application, due to the impact, vibration and other alternating loads, as well as the influence of heat, deformation and other factors, coupled with rapid wear and other reasons, it is easy to Make the originally fastened parts loose. 4. Leakage of truck-mounted drilling rig Due to the looseness of the parts of the truck-mounted drilling rig, vibration and the influence of the heat of the machine, the sealing surface of the machine and the pipe joints will appear leakage. Some shortcomings such as casting and processing are difficult to invent during assembly and debugging. However, due to the vibration and impact in the operation process, this shortcoming is exposed, which is expressed as oil (water) leakage (seepage). Therefore, the run-in period easily emerge leakage phenomenon. 5, truck-mounted drilling rig operation errors Due to the lack of understanding of the structure and performance of the truck-mounted drilling rig machine (especially the new operator), it is easy to cause failures due to operational errors and even cause mechanical accidents.

Taboo of Deep Well Drilling Machine Maintenance

After adjusting the oil supply start time, the reason for checking the stroke margin is because the stroke margin of the plunger is related to the wear of the plunger and the sleeve. After the plunger and sleeve are worn, the plunger needs to move up a little more to start oil supply, which will delay the start of oil supply. When the adjusting bolt is loosened or replaced with a thicker adjusting block or washer, the lower position of the plunger will move upward, thereby reducing the stroke margin of the plunger. Therefore, when repairing and debugging the fuel injection pump, the stroke margin should be checked first to determine whether the fuel injection pump can still be adjusted.

Drilling hole forming process

In the process of drilling and hole forming by crawler drilling rig, according to the change of formation and hole depth, the drilling parameters and drill bit are reasonably selected, and the mud is modulated in time to ensure the hole forming quality. When entering the sand layer and pebble layer, the footage speed should be appropriately slowed down, the consistency of the mud should be improved, and the footage of each drilling return should be reduced to ensure the stability of the hole wall. During drilling construction, the front shovel shall be used to remove the drilling slag in time to ensure the site is clean and tidy, which is conducive to the next construction. After the drilling reaches the required hole depth and the drilling is stopped, pay attention to maintain the slurry surface elevation of the mud in the hole to ensure the stability of the hole wall.

Classification and working principle of water well drilling rig

The vertical reciprocation of the drill bit causes the drill bit to strike the bottom hole to break the rock formation. The structure is simple, but there is no circulating cleaning system, and the removal of chips and drilling machines cannot be carried out at the same time, so the work efficiency is low. The drilling depth is generally within 250 meters, and some can reach 500 to 600 meters. The main types are as follows. A simple percussion drill that uses the weight of the drill bit itself to impact the formation. At the lower end of the drill are some collapsible pointed flaps.

Routine Maintenance Method of Drilling Rig

Daily maintenance of compact rotary excavator drilling rigs for small drilling rigs: The lifting device using a lifting device is also called "reverse active joint" and "destructive force device". It is an important part of small drilling rig manufacturers in lifting drill pipes and tools. The structure and performance of the main hoisting wire rope and the inductor are connected together 2. a small type drilling rig, and the drill pipe at the top is on top. When the main hoisting wire rope shrinks, the rotary drill pipe and drill bit can be improved. When the power head rotates, the drill bit is drilling the ground and throwing earth. As the drill pipe force changes. After its own rotation, it eliminates the change caused by the rotation of the wire rope due to the rotation of the drill pipe.
