Precautions For Reaming Bit Maintenance

  • Pay attention to the use and maintenance of Reaming Bit during the running-in period. So, what are the aspects?

     

    1. The operator should receive training and guidance from the manufacturer, fully understand the structure and performance of the water well drilling rig, and obtain certain operation and maintenance experience before operating the machine. The product operation and maintenance manual provided by the drilling rig manufacturer is the necessary information for the operator to operate the equipment. Before operating the machine, be sure to read the operation and maintenance manual, and perform operation and maintenance in accordance with the requirements of the manual.

     

    1. Pay attention to the workload during the running-in period. Generally, the working load during the running-in period should not exceed 80% of the rated working load, and an appropriate workload should be arranged to prevent the occurrence of overheating caused by the continuous operation of the machine for a long time.

     

    1. Pay attention to always follow the instructions of each instrument. If there is any abnormality, it should be stopped and eliminated in time. If the cause is not found and the fault is not eliminated, the operation should be stopped.

     

    1. Pay attention to frequently check the level and quality of lubricating oil, hydraulic oil, coolant, brake fluid, and fuel (water) fluid, and pay attention to checking the airtightness of the whole machine. Excessive oil and water were found during the inspection, and the cause should be analyzed. At the same time, the lubrication of each lubrication point should be strengthened. It is recommended to add grease to the lubrication points during the running-in period (except for special requirements).

     

    1. Add grease to the jack before the machine works, because the dirty water containing silt is easy to enter, it will wear the bearing and reduce the sensitivity of the jack of the drilling rig. The machine must be kept clean, and the loose parts must be adjusted and tightened in time to prevent the loose parts from aggravating the wear of the parts or causing the loss of the parts.

     

    1. At the end of the running-in period, perform mandatory maintenance on the machine, check and adjust, and pay attention to changing the oil. In addition, check the oil quantity and quality of the oil tank before work, check whether the oil quantity of each reducer is sufficient and whether the oil quality is normal.

     

    1. Check the steel structure for damage such as cracks, corrosion, desoldering, etc. Check whether the main and auxiliary wire ropes have broken wires and whether the joints are intact and safe.

     

    1. Check and replace the grease of the thrust bearing of the plate valve of the manual water well drilling rig.

     

    The thrust bearing of the plate valve of the manual water well drilling rig adopts lithium-based grease. The consumption of grease should be checked after each maintenance. If it is found to be deteriorated, contaminated or lacking, it should be replaced or supplemented immediately. The valve cavity should be inspected in time during each inspection. Flush and refill the sealing grease to lubricate the valve plate and valve seat.

     

    In the maintenance process, if there is a slight leakage at the valve stem sealing packing seal, the sealing grease can be injected into the valve through the sealing grease injection valve on the valve cover to prevent leakage, but the seal should be replaced in time after the construction is completed. fully. Before refilling the valve with sealing grease, the internal pressure of the valve body must be considered. The pressure of the high-pressure injection gun used must be greater than the internal pressure of the valve to successfully inject the sealing grease. Fill the injection gun with sealing grease and connect it to the injection valve on the valve cover through a hose. Operate the injection gun and inject the sealing grease.

     

    In short, the maintenance requirements of Extension Drilling Tools during the running-in period can be summarized as: reduce load, pay attention to inspection, and strengthen lubrication. As long as you pay attention to and implement the maintenance and maintenance of construction machinery as required during the running-in period, you will reduce the occurrence of early failures, extend the service life, improve work efficiency, and bring you more economic benefits.
