The operating environment of marine and offshore engineering equipment is much harsher than land-based scenarios: high salt spray, high humidity, continuous vibration, and rolling and tilting all place higher requirements on the corrosion resistance and stability of vacuum systems. Traditional oil-lubricated vacuum pumps not only require frequent oil changes, but their oil mist emissions are also difficult to meet engine room environmental protection and safety regulations. Leynow marine vacuum pumps adopt an oil-free structure and anti-corrosion treatment, and are widely used in key ship systems such as vacuum sewage, vacuum condensation, oil-water separation, and cargo hold drying.
Challenges Faced by the Industry
The requirements of ships and offshore equipment for vacuum systems are not just about "pulling a vacuum", but more importantly, corrosion resistance, anti-rolling, and easy maintenance. In practical applications, shipyards and shipowners often encounter the following types of problems:
Severe Salt Spray Corrosion
The high-salt and high-humidity marine environment accelerates the corrosion of pump bodies and pipelines. The lifespan of some vacuum pumps is easily affected, and the failure rate increases.
Rolling and Tilting Working Conditions
Ships continuously tilt and roll during navigation. Oil-lubricated pumps are prone to oil surging and lubrication failure, affecting vacuum degree stability.
Difficult Offshore Maintenance
Short port stays and limited offshore maintenance conditions mean equipment usually needs to have a long service life, low maintenance, and easy replacement characteristics.
Emission and Compliance Requirements
Engine room oil mist emissions and bilge water treatment need to meet anti-pollution conventions and classification society standards, and equipment must be easy to inspect and record.
Leynow Marine Industry Solutions
Targeting the actual working conditions of ships and marine engineering, Leynow provides overall vacuum solutions centered on marine oil-free vacuum pumps, forming a complete closed loop from equipment selection and anti-corrosion configuration to port service.
Salt Spray Resistant and Anti-corrosion Design
