Problems solved by technology

[0006] The technical problem to be solved by the present invention is: as the diesel engine speed increases, the vibration of the diesel engine will increase. The defect of the silicone oil shock absorber is that as the vibration of the diesel engine increases, its frictional damping cannot be automatically adjusted to increase, and the vibration damping effect will decrease. Reduced, the diesel engine will resonate and damage the equipment

Embodiment Construction

[0024] The innovative specific implementation of the present invention will be further described below in conjunction with the implementation examples and the accompanying drawings.

[0025] The ship diesel engine dual-feedback silicone oil damping system provided by the present invention has a structure such as Figure 1 to Figure 3 As shown, it is mainly composed of a double-feedback governor connected by an oil circuit, a silicon oil pressure controller, a silicon oil shock absorber and a silicon oil pressurization system 22 .

[0026] The double-feedback governor is a governor improved on the basis of the original diesel engine double-feedback governor, specifically: figure 1 As shown, a silicon oil pressure regulating rod 8 is added to the lower end of the connecting rod of the power piston. The back pressure in the road, so as to achieve the effect of adjusting the pressure of the silicone oil shock absorber.

[0027] The silicone oil pressure regulating rod 8 is used ...

Abstract

The invention provides a double-feedback silicone oil shock absorption system of a marine diesel engine. The double-feedback silicone oil shock absorption system comprises a double-feedback speed regulator, a silicone oil shock absorber and a silicone oil pressurization system which are connected through oil paths. The silicone oil shock absorber and a double-feedback speed regulation system of the diesel engine are combined through the silicone oil pressurization system, so that under the action of the silicone oil pressurization system, the pressure of silicone oil in the silicone oil shock absorber is changed through changes of hydraulic oil in the double-feedback speed regulator, and frictional damping and the shock absorption effect of the silicone oil shock absorber are increased along with increase of the rotating speed of the diesel engine; and therefore, vibration of the diesel engine is effectively reduced, and damage to the diesel engine is reduced. The double-feedback silicone oil regulation system is fully utilized for carrying out self-adaptive regulation on the pressure of the silicone oil in the silicone oil shock absorber, and therefore the acting strength of the shock absorber on shock absorption of the diesel engine is further regulated. Thus, the double-feedback silicone oil shock absorber system and device of the marine diesel engine have economic performance, practicality and the function of reducing damage to the marine diesel engine.

Description

technical field [0001] The invention relates to a double-feedback silicone oil damping system for marine diesel engines. The dual-feedback silicone oil adjustment system self-adapts the silicone oil flow in the silicone oil shock absorber, thereby further adjusting the strength of the shock absorber's effect on the diesel engine's vibration reduction, thereby achieving the purpose of diesel engine vibration reduction. Background technique [0002] For ships operating at sea, the vibration of the internal combustion engine will reduce the service life, work efficiency and reliability of the internal combustion engine, damage various connecting pipes, and cause vibration and noise pollution to the surrounding environment. The environmental vibration caused by this not only deteriorates the working conditions of other equipment and instruments, but also has adverse effects on the staff and passengers. Therefore, it is necessary to install a marine diesel engine double feedback ...
