There are five ways to maintain a rotary drilling rig engine. The engine is the heart of the machine and its most critical component. However, operators may neglect it during the drilling and piling process, leading to problems. Today, let's learn a few tips for maintaining a rotary drilling rig engine.#pile drilling rig#
1. Running-in: This is fundamental to extending the service life of a diesel engine. Whether it's a new engine or one undergoing an overhaul, a run-in is required before normal operation.
2. Cleanliness: This refers to clean oil, water, air, and the machine. Diesel is the primary fuel for rotary drilling rig engines. Impure diesel can cause wear of delicate components, widen clearances, lead to oil dripping, leakage, and insufficient oil pressure, resulting in poor combustion and reduced power. Similarly, impure engine oil can cause abrasive wear between the journal and bearing, widen clearances, reduce oil pressure, and even lead to serious problems such as oil channel blockage, shaft seizure, and bearing burns. Excessive dust in the air accelerates wear of the cylinder liner, piston, and piston rings, shortening their service life. Impure cooling water will cause scale buildup in the cooling system, impacting engine heat dissipation, increasing engine temperatures, deteriorating lubrication conditions, and causing severe wear and tear on engine components. A dirty, heavily contaminated engine surface can corrode the engine, shortening its lifespan.#pile drilling rig#
3. Inspection: Regularly inspect fasteners. Diesel engines are subject to vibration, impact, and uneven loads during use, which can easily loosen bolts and nuts, especially those connecting the connecting rod, cylinder head, and flywheel housing.
4. Sufficient oil: Sufficient water, sufficient oil, and sufficient air. Inadequate or interrupted diesel and air supply can lead to starting difficulties, poor combustion, black smoke, reduced power, and even malfunction. Insufficient or interrupted oil supply can lead to poor lubrication, severe wear on engine components, and even bearing burnout. Insufficient cooling water can cause excessive engine temperatures, reduced power, and shortened engine lifespan.
5. Adjustment: The diesel engine's valve clearance, valve timing, decompression clearance, fuel injection advance angle, and injection pressure should all be regularly inspected and adjusted to ensure the engine is always in good working order.
