Technical Field
The invention relates to the technical field of water supply equipment of engines, in particular to a high-pressure water supply device for an engine.
Background
At present, an underwater vehicle engine needs to carry an oxidant by itself, so that the combustion efficiency of the explosive charge is low. With the continuous progress of technology, it is very urgent to achieve higher combustion efficiency with limited charges. Compared with the traditional propulsion mode, the oxygen-enriched combustion which does not carry the oxidant and adopts a large amount of outside water as the oxidant greatly increases the combustion efficiency.
When the engine is operated, the pressure in the combustion chamber is generally high, and therefore, in order to supply water as an oxidizing agent into the engine, the water supply pressure needs to be increased to be higher than the pressure in the combustion chamber of the engine to supply water at high pressure. The existing engine water supply device adopts a one-way water supply single-valve control system, and the system cannot effectively regulate the water supply flow. When the water supply pressure is one, the water supply flow of the water supply system is constant, which is not suitable for some engines with special charges, and meanwhile, air is remained in the water supply system, so that the water supply delay is difficult to avoid, and high-pressure water cannot be quantitatively supplied into the engine to participate in reaction.
