Description

technical field

[0001] The invention relates to a hydraulic system, in particular to a transient hydraulic system which can be adjusted in multiple working conditions. Background technique

[0002] With the strengthening of the country's economic and technological strength, sophisticated science and technology have been continuously applied to various military equipment. As a part of it, the water pump plays a vital role in the ship's water jet propulsion system, weapon launch system and rocket launch system. For example, the water pump is used to collect energy to promote the operation of the equipment; the structure is adjusted by frequency conversion to change the operating speed of the water pump to realize the variable working condition operation of the equipment. The traditional hydraulic system can only meet the continuous supply of hydraulic pressure, but lacks the ability of transient supply, and cannot immediately start and shut down the system. The transient hyd...
