In response to increasingly stringent environmental protection standards, a growing number of drilling sites are adopting drilling cuttings vertical centrifuges to achieve solid-liquid separation and minimize waste volume. As high-speed rotating equipment, scientific and reasonable daily maintenance and upkeep are crucial for the long-term stable operation of the vertical centrifuge. Kosun, specializing in the research, development, and manufacturing of solid control and cuttings treatment equipment for many years, has drawn on extensive field experience to compile a set of practical maintenance recommendations. These suggestions aim to help users effectively extend equipment life and enhance processing efficiency.
I. Timely Maintenance of the Lubrication System is Essential
Approximately half a month after the equipment is put into use, the lubricating oil should be changed for the first time. Subsequently, the oil filter screen should be cleaned once a month, and oil quality should be monitored. The frequency of subsequent oil changes should be reasonably determined based on the degree of contamination, but should not exceed a maximum of six months. When replacing with new oil, it is recommended to thoroughly clean the oil pipes, filter screen, and oil tank. If the filter screen is found to be worn, it should be replaced promptly. Simultaneously, check the sealing of all oil pipe interfaces to prevent leakage. The oil level should be checked via the oil sight glass every two weeks and replenished if found to be insufficient.
The main motor and the oil pump motor use independent grease lubrication; grease should be replenished approximately every 2500 hours of operation to ensure smooth running. If abnormal temperature rise, oil pressure fluctuation, or oil deterioration is observed during operation, the equipment should be stopped immediately for troubleshooting to avoid damage to the main shaft or rotor.
II. Daily Operational Checks Cannot Be Overlooked
A routine inspection should be carried out during each shift, focusing on the following aspects:
Whether the equipment vibration is stable, and if there is any abnormal noise;
Whether the main bearing temperature is within the normal range (≤90℃);
Whether connecting bolts show any signs of looseness;
Whether slag discharge and mud outlet are unobstructed, and if the feed/discharge ports are blocked;
Whether the lubrication system has oil leakage or other anomalies.
Upon discovering any abnormality, the equipment should be stopped immediately for handling and hidden dangers eliminated.
III. Regular Maintenance Keeps Equipment As Good As New
Approximately every 1000 hours of operation, the tension of the V-belts should be checked and replaced immediately if severely worn; simultaneously, check if all machine fasteners and sensor connections are secure. The oil filter should be cleaned once a month, and the oil quality re-evaluated; if the oil becomes cloudy or impurities increase, it should be changed earlier than scheduled. Additionally, the mud scraper handle should be operated once every two hours to prevent material buildup from affecting the dewatering effect.
Through scientific maintenance and management, the drilling cuttings vertical centrifuge can not only significantly improve drilling waste fluid treatment efficiency but also effectively reduce subsequent maintenance costs. Kosun consistently adheres to the design philosophy of “reliable equipment and convenient maintenance,” providing customers with efficient, environmentally friendly, and economical overall solutions for cuttings treatment, allowing every centrifuge to achieve its maximum value on site.
