The fitted bolt, marked with code number K 31024, is a specialized fastener used in the crankshaft assembly of the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 diesel engine. Unlike standard bolts, fitted bolts are machined for an exact fit within the crankshaft’s mounting holes, providing enhanced shear strength and precise alignment. This ensures minimal play and maximum structural integrity, especially important under the intense loads and rotational forces present in large diesel engines. The fitted bolt is crucial for maintaining crankshaft geometry and operational reliability, supporting the engine’s performance and durability across prolonged use.
The bolt identified by code number K 31022 is specifically designed to fasten the crankshaft counterweight (K 31020) in place within the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 diesel engine. This high-strength fastener plays a vital role in maintaining the secure and precise attachment of the counterweight, ensuring balance and alignment during high-speed engine rotations. Engineered to withstand the stresses and vibrations of long-term operation, the bolt’s reliability is essential for engine stability. Regular inspection and proper torque application during assembly are crucial to prevent loosening or mechanical failure.
The counterweight, bearing code number K 31020, is a critical component of the crankshaft system in the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 diesel engine. Its primary role is to balance the rotating mass of the crankshaft, reducing vibrations and mechanical stress during engine operation. By offsetting the reciprocating forces of the pistons and connecting rods, the counterweight contributes to smoother rotation, improved engine efficiency, and prolonged component life. Manufactured to precise tolerances and from high-strength materials, this counterweight ensures stable performance even under the engine’s most demanding load conditions.
The valve seat, marked by code number K 27702, is a precisely machined component designed for use with valve K 27703 in the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 diesel engine. It provides the sealing surface against which the valve closes, playing a critical role in maintaining pressure integrity and preventing leakage. Made from wear-resistant materials, the valve seat must endure repeated cycles of high-pressure contact, ensuring long-term durability and consistent performance. Its quality and proper fit are essential to the reliable function of the relief valve system and the overall pressure control within the engine.
The spring housing, identified by code number K 27701, is an essential part of the relief valve assembly in the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 engine. This housing encases the spring mechanism that governs the opening pressure of the relief valve. Built for durability and precise alignment, it ensures that the spring operates under optimal tension, providing consistent pressure control. A well-maintained spring housing supports accurate valve function and prevents pressure anomalies that could lead to system imbalances or component wear, making it critical for safe and efficient engine performance.
The complete relief valve, designated with code number K 27700, is a vital safety component in the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 diesel engine. This valve is engineered to protect the engine’s systems from excessive pressure buildup by automatically releasing pressure when it exceeds safe operating limits. Designed for reliability and quick response, the relief valve ensures the longevity and stable performance of the engine under high-stress conditions. Its robust construction and precision calibration make it a key element in maintaining engine safety and operational balance, particularly in demanding marine and industrial environments.
