Ship and ocean engineering diesel engine cooling system and cooling method thereof

Abstract

The invention belongs to the field of diesel engine cooling, particularly relates to a ship and ocean engineering diesel engine cooling system and a cooling method thereof, and provides the following scheme aiming at the problems that an existing diesel engine cooling system is low in water circulation utilization rate, not ideal in cooling effect, low in temperature change adjustment matching tacit degree and low in cooling efficiency. The system comprises an information acquisition module, the information acquisition module comprises a temperature acquisition unit, a picture acquisition unit, a flow velocity acquisition unit and an information transmission unit, and the information acquisition module is used for acquiring the environment around the diesel engine and sending the acquired information out in time. According to the diesel engine cooling system, data of the diesel engine can be monitored and connected in real time, cooling data can be correspondingly matched and adjusted according to data of equipment, the water circulation utilization rate is high, the matching tacit degree with temperature change adjustment is high, and the cooling efficiency is high.

Description

technical field [0001] The invention relates to the technical field of diesel engine cooling, in particular to a diesel engine cooling system and cooling method for ships and marine engineering. Background technique [0002] The major of shipbuilding and ocean engineering is a discipline that studies the working principles of ship turbines. It mainly studies the knowledge of ship structure, navigation principles, safety design and construction regulations, and the specifications of important classification societies at home and abroad, and studies ship design methods and How to ensure the rapidity of navigation, good maneuverability and anti-wind and wave ability, etc., the external circulation cooling water pump of the marine diesel engine is used to pump the river water / sea water outside the ship to supply the diesel engine to cool its pressurized air, lubricating oil and body In the traditional design, the external circulation cooling water pump of the marine diesel engin...

[0002] The major of shipbuilding and ocean engineering is a discipline that studies the working principles of ship turbines. It mainly studies the knowledge of ship structure, navigation principles, safety design and construction regulations, and the specifications of important classification societies at home and abroad, and studies ship design methods and How to ensure the rapidity of navigation, good maneuverability and anti-wind and wave ability, etc., the external circulation cooling water pump of the marine diesel engine is used to pump the river water / sea water outside the ship to supply the diesel engine to cool its pressurized air, lubricating oil and body In the traditional design, the external circulation cooling water pump of the marine diesel engine is mostly an external type, which is connected with the pulley of the diesel engine through a belt. After the diesel engine is started, the external circulation cooling water pump is driven by a belt drive to extract the external The purpose of seawater, however, the existing diesel engine cooling system has a low water recycling rate, and the cooling effect is not ideal, and the tacit cooperation with the temperature change adjustment is low, resulting in low cooling efficiency
