Rotary drilling rig is a new type of piling machinery, which plays a vital role in the construction of pile foundation in recent years. Small rotary drilling rig is simple to operate, only one person can be used in the construction process, and the hole speed of small rotary drilling rig is also very fast, more and more engineering construction have used it. How to maintain it during use or when it is usually parked is a very critical issue. The following describes several rotary drilling rig maintenance methods and precautions.
The oil and filter element must be replaced after the first use of the rotary excavator for 50 hours, and the subsequent use will be replaced once in 250 hours under normal circumstances; The power head gear oil should be replaced every 2000 hours of work, the power head reducer gear oil must be replaced after 50 hours for the first time, and the replacement time of the hoist gear oil is the same as that of the reducer. Replace the hydraulic oil every 3,000 hours, and replace the filter every 500 hours. The oil-water separator is discharged once a day, the diesel tank is discharged once a day, the fuel tank is cleaned once every six months, and the filter element is replaced according to the actual situation; The drill pipe bearing and tractor should be buttered once a day, and the fuselage should be rotated once a month; The engine coolant should be changed every two hours, and the filter element should be changed every 1,500 hours or once a year.
