Pneumatic hydraulic top bracing devices are primarily used in MAN, B&W, and WARTSILA marine power plants. The configuration of the top bracing device depends on the models or requirements of the diesel engine.
|Model||Diameter of top bracing hydraulic cylinder||Axial Max. load for single cylinder||Axial Min. load for single cylinder||Installing length and tolerance of hydraulic cylinder (L)||Working stroke||Air supply pressure of compressed air||Pressure setting of high pressure overflow valve||Hydraulic oil|
|QYDZ300||300mm||127kN||28kN||475± 5mm||±15mm||0.5-1.0 MPa||1.7±0.05 MPa||N32 or SAE10-30|
|QYDZ300A||300mm||183.8kN||85kN||585±5mm||±15mm||2.5-3.0 MPa||2.6±0.05 MPa||N32 or SAE10-30|
Standalone hydraulic top bracing system is installed on the starboard side of the engine (exhaust side), but portside installation (camshaft side) is available if needed. Installation is only necessary on one side.
