The support ring with code K 74131 is a key structural element in the fuel transfer pump of the Sulzer ZV40/48 engine. Positioned between the pump housing and mounting bracket, it ensures precise alignment and absorbs radial and axial loads generated during operation. By keeping the pump assembly firmly centered, this ring minimizes vibration and wear on internal components. Crafted from high-strength, corrosion-resistant material, it guarantees long-term stability and contributes to the smooth, reliable delivery of fuel under demanding marine or industrial conditions.
Oil piping in the MAN L21/31 engine forms the network that transports lubricating oil to various engine parts, including bearings, pistons, and camshafts. This system ensures continuous lubrication under high pressure and temperature, reducing friction and wear. Maintaining the integrity and cleanliness of oil piping is critical to preventing oil leaks, contamination, and ensuring the engine’s smooth and reliable operation.
Cylinder covers with valves are integral parts of the MAN L21/31 engine that seal the top of each cylinder while housing intake and exhaust valves. These covers protect the combustion chamber and allow precise control of airflow in and out of the cylinder. Proper maintenance and sealing of cylinder covers ensure efficient engine operation, optimal combustion, and prevent leaks that could lead to performance loss or mechanical issues.
The silencer and charge air filter in the MAN L21/31 engine are crucial components for ensuring clean air intake and noise reduction. The charge air filter removes contaminants from the compressed air before it enters the engine, protecting internal components from damage and maintaining combustion efficiency. The silencer reduces exhaust noise, helping the engine comply with environmental noise regulations and providing a quieter operation, essential for both marine and industrial applications.
The locking screw identified as K 73134 is a small but vital component used to secure parts within the raw water pump of the Sulzer ZV40/48 engine. Its function is to maintain tight fastening and alignment of components, even under conditions of vibration and thermal expansion. Properly torqued, this screw prevents leaks and potential mechanical failure, contributing to the overall stability and performance of the cooling system. Regular inspection ensures its continued reliability in demanding marine environments.
The casing with code number K 74102 provides robust protection and structural integrity for the fuel transfer pump in the Sulzer ZV40/48 engine. It houses and supports all internal moving components while also forming a tight seal to prevent fuel leakage. Manufactured to withstand the pressures and thermal stresses of diesel engine operation, this casing ensures the pump performs efficiently and safely under continuous use. It plays a key role in maintaining the engine’s steady fuel supply.
