Introduction
The M/E hydraulic lateral supporting device can change the intrinsic frequency of the engine when resonance occurs during normal operation. The M/E hydraulic lateral supporting device protects the engine, and slows degradation of the hull caused by loading and unloading.
Application
M/E hydraulic lateral supporting devices are used in WARTSILA main engines. Specific models can be selected according to the parameters recommended by the main engine factory.
Features
- The M/E hydraulic lateral supporting device consists of the fixed rod of main engine, the adjustable bearer, hydraulic cylinder, hydraulic accumulator and pressure gauge.
- The structure of the hydraulic cylinder comes in two forms for users to choose from: Form I is whole, while Form II is separated into the hydraulic cylinder and hydraulic accumulator. The two sections are connected by 10 x 1 copper pipes, or seamless steel pipes, which are supplied and connected by the shipyard.
