1. Hydraulic component cleaning should be carried out on a dedicated cleaning platform, and should not be done anywhere. Keep away from sources of pollution and the cleaning area should be clean. 2. The cleaning solution allows the use of kerosene, gasoline, and hydraulic oil with the same brand as the hydraulic system working oil. 3. The cleaned parts should not be wiped with cotton, linen, silk, or synthetic fabrics to prevent the fibers from falling off and contaminating the system. 4. After cleaning the drilling tool components, they should not be directly placed on the ground, cement floor, floor, bench and assembly workbench. They should be placed in a container with a lid and filled with clean hydraulic oil. 5. It is best to take protective measures for cleaned components and keep them away from oxidative pollution.

The mandatory maintenance of drilling tools is the most basic requirement for ensuring the normal operation of equipment, which requires relevant personnel to strengthen the daily maintenance of equipment to ensure that there are no abnormalities. Relevant personnel should regularly inspect the equipment and keep records of its specific condition. Any abnormal equipment should be reported in a timely manner and dealt with according to the degree of abnormality. Equipment that exceeds its service life should be forcibly eliminated to fundamentally reduce equipment failure problems. In addition, advanced detection technology should be utilized in the mandatory maintenance of petroleum drilling machinery and equipment to control equipment failures in advance, minimize equipment failure losses, and save economic funds for enterprises. Although some drilling equipment failures are difficult to avoid, many of them can be controlled by using lubricants. Through actual investigation, it has been found that more than half of the faults in drilling equipment are caused by inadequate lubrication work. Therefore, in order to ensure the normal use of equipment, it is necessary to use lubricants reasonably. In the process of using lubricants, it is important to note that different types of mechanical equipment have different lubricant configurations, which requires relevant personnel to choose the appropriate lubricant based on the equipment structure and natural conditions. In addition, it is necessary to choose lubricants with good lubrication effects, and ensure that the supply of lubricants can meet the needs of daily maintenance and emergency handling of equipment, to ensure that the equipment does not wear out.

Fatigue wear is the mechanism of rolling or rolling erosion wear on the surface of rotary excavator drill rods, which is mainly manifested in the form of microcracks and micro cutting during low angle erosion; During high angle erosion, crack propagation and brittle fracture are the main mechanisms. During the operation of the drill string, the rotation speed is relatively high, and the relative velocity with the drilling fluid is also high. If the viscosity and weight of the drilling fluid are high, the sand content is high, and the drilling is carried out for a long time, it will cause significant erosion and wear to the drill string. Abrasive wear is a phenomenon caused by the relative motion of external hard particles or hard surface micro peaks on the surface of rotary excavator drill rods, resulting in surface abrasion and material detachment. The surface characteristics of rotary excavator drill rod columns are abrasion tearing, longitudinal tensile marks, local peeling, and cracks. The mechanism of abrasive wear is micro cutting, where multiple plastic deformations lead to fracture and micro fracture. The drill string is prone to significant bending under composite stress conditions, resulting in severe friction between the protruding areas and the hard rock layers. The quenching treatment thickness on the surface of the drill string is generally 1mm. After the quenching layer wears off, the wear rate will accelerate in the future. In deep hole drilling, sometimes there are obvious scratches on the surface of the extracted drill rod, which is a manifestation of abrasive wear. After using the drill collar for a period of time, we will find that there will be varying degrees of wear, and of course, some wear is inevitable. Because in the use of rotary excavator drill rods, there may be friction between various components, so it is not surprising to see wear and tear.
