Hydraulic starting energy storage device of diesel engine

Abstract

The invention discloses a hydraulic starting energy storage device of a diesel engine, which comprises a manual pump starting system and a motor pump starting system, wherein the manual pump output end of the manual pump starting system is connected with an energy accumulator sequentially through a first check valve and an energy accumulator stop valve oil inlet end and connected with a hydraulicmotor input end through a high-pressure ball valve; the motor pump output end of the motor pump starting system is connected with the energy accumulator sequentially through an unloading valve and the energy accumulator stop valve oil inlet end; the motor pump output end is also connected with the energy accumulator sequentially through a second check valve and an energy accumulator stop valve input end; and an unloading valve remote control opening is connected with the energy accumulator through the energy accumulator stop valve input end. The invention has the advantages of compact structure, simple operation and control, low noise and high reliability. A motor pump is adopted for automatically delivering pressure oil to the energy accumulator, thus the labor intensity for delivering pressure oil to the energy accumulator is reduced, the working efficiency of the hydraulic starting energy storage device is improved and reliable guarantee is provided for the diesel engine hydraulic starting of a lifeboat.

Description

technical field [0001] The invention relates to a starting device for a diesel engine, in particular to a device capable of automatically storing hydraulic energy when the diesel engine is working, and belongs to the technical field of diesel engines. Background technique [0002] The biggest advantages of hydraulic starting of diesel engines are: fast starting speed, reliable operation, especially no sparks during the starting process, so it is suitable for starting diesel engines in explosive gas environments such as oil platforms and tankers. Especially after the diesel engine of the lifeboat is started, it is necessary to store energy in the accumulator immediately to prevent the lifeboat from overturning in strong winds and waves during driving, and the diesel engine is turned upside down. At this time, the hydraulic energy stored in the accumulator is used to start the lifeboat again. diesel engine, so that the lifeboat can resume normal operation. [0003] Patent No....

AI Technical Summary

Problems solved by technology

However, lifeboats generally work in high-risk sea conditions. During driving, manual pumps are used to deliver pressure oil to the accumulator for energy storage. Not only is the labor intensity high, the energy storage time of the accumulator is long, and the space of the lifeboat is small. The interior is bumpy during travel, especially in the state of full occupancy, which brings a greater safety risk to the operation of the manual pump
