Application

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.

Parameters

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

Features

The pneumatic hydraulic top bracing system consists of a top bracing hydraulic cylinder, hand pump station and optional control panel.
Pneumatic hydraulic top bracing systems are installed between the engine and the hull of a ship in order to reduce vibration frequency caused by the engine.
The top bracing system is flexible and can easily handle the longitudinal and lateral displacement that results from temperature and loading changes, making it safer and more reliable than a rigid support structure (friction plate).
The top bracing system consists of two or four top bracing cylinders depending on customer requirements.

Installation

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.
