The locking screw with code K 73034 is a seemingly small but essential fastening element designed for securing the casing of the cooling water pump in the Sulzer ZV40/48 engine. Its primary function is to hold the casing parts in position under pressure, vibration, and thermal expansion, preventing any misalignment or leakage. Precision-engineered and built to withstand mechanical stress, this screw contributes directly to the durability and stability of the entire cooling system. Regular inspection and correct torque application are key to ensuring its effectiveness.
The bearing housing marked with code K 73111 is a critical structural component within the raw water pump assembly of the Sulzer ZV40/48 diesel engine. This housing securely encases the pump bearings, maintaining their alignment and protecting them from contaminants such as water and debris. Its robust construction ensures that the bearings operate smoothly under heavy load and variable speed conditions. By minimizing vibration and allowing consistent rotation of the pump shaft, this component plays a vital role in ensuring the reliability of the engine’s cooling system.
The connecting rod in the MAN L21/31 engine transfers the piston's reciprocating motion into the crankshaft’s rotational motion. Made from high-strength forged steel, it must endure significant forces and dynamic loads. Its sturdy construction and precise design are vital for reliable and efficient power transmission in the engine.
The water guide jacket in the MAN L21/31 engine directs coolant flow around the cylinders and key engine parts to maintain optimal temperatures. By managing heat distribution effectively, it helps prevent overheating and supports engine durability and consistent performance in demanding conditions.
The valve camshaft in the MAN L21/31 engine controls the timing and movement of the intake and exhaust valves. It ensures precise valve operation, optimizing combustion efficiency and overall engine performance. Manufactured with high precision and durability, this camshaft is critical for the smooth and reliable functioning of the engine’s valve train.
The complete raw water pump with code K 73100 plays a central role in the Sulzer ZV40/48 engine's cooling system. It is responsible for drawing seawater or external cooling water into the engine to absorb heat from critical components such as cylinder heads and exhaust systems. Engineered for robust performance and corrosion resistance, this pump ensures stable thermal regulation under high-load maritime conditions. Its reliable function is essential for preventing overheating and sustaining engine longevity.
