Advantages of Rotary Drilling Rig Hole Formation

Advantages of Used Rotary Drilling Rig Hole Formation

(1) Compared with manual hole digging piles, it can ensure the personal safety of construction personnel.

(2) Fast construction speed, especially in sandy soil and backfill soil, 1 to 4 piles can be constructed per day.

(3) The mechanical equipment is relatively simple and convenient, requiring only a self-propelled crane, a rotary table mounted on the crane, a drill pipe, and a bucket drill bit. These can be pre-assembled together. After arriving at the site, the used rotary drilling rig can be standardized, and the equipment can walk to the pile position to start drilling.

(4) Verticality, hole diameter, elevation, and virtual soil at the hole bottom can be well controlled, which is very beneficial for ensuring project quality.

(5) Low vibration and noise.

How to Maintain the Swivel of a Small Rotary Drilling Rig

How to Maintain the Swivel of a Small Rotary Drilling Rig

The swivel plays a major role in a small rotary drilling rig. The small rotary drilling rig connects the drill pipe and the main winch wire rope through this component, and it needs to rotate frequently during operation. The output torque of the reducer is transmitted to the swivel through the meshing of the power head slewing support and the drill pipe. To ensure the normal operation of the small rotary drilling rig, the swivel must rotate normally to eliminate torsional torque. This requires us to regularly maintain the swivel. The editor summarizes the following methods for maintaining the swivel of a small rotary drilling rig. First, to properly maintain the swivel, we must understand its structure. The swivel of a small rotary drilling rig is composed of an upper joint, a lower joint, an intermediate body, a pin shaft, a thrust bearing, and a skeleton oil seal. First, the installation sequence must not be messed up, and it must be kept clean during installation. After installation, fill it with lubricating grease to keep it rotating flexibly. Second, during use, regularly add lubricating grease every 12-16 working hours to discharge the old grease. Third, when using the mud wall protection method, regularly check whether the swivel oil seal is damaged. If damaged, replace it in time. Fourth, during the operation of the small rotary drilling rig, observe the working status of the winch rope at any time to avoid rope entanglement. If the swivel is found to be damaged, remove it for repair in time to prevent accidents. The editor reminds colleagues in the construction machinery industry to pay attention to the maintenance and care of their engineering equipment. When a machine has an accident, it not only requires equipment repair but also causes losses due to delays in the project schedule. Please read the above content carefully.

The phenomenon of engine oil turning black is a common topic, but hydraulic oil turning black seems not to have been specifically discussed.

Today, several reasons for hydraulic oil turning black in rotary drilling rigs:

Influence of metal impurities

1. It may be wear debris generated by the high-speed rotation of the pump. You must consider all components related to the pump rotation, such as bearings, volume chambers, etc.; 2. Wear debris generated by the back-and-forth movement of the hydraulic valve spool and the back-and-forth movement of the oil cylinder, but this phenomenon will not occur in a short time; 3. For a new machine, a large amount of iron filings will be generated during equipment running-in. I don't know whether you completely emptied the hydraulic oil in the oil tank when changing the oil, and after circulating the new oil through the system, wiped the oil tank clean with cotton cloth before adding new oil. If not, a large amount of iron filings may remain in the oil tank, which will also cause the new oil to be polluted and turn black.
