A transient hydraulic system that can be adjusted in multiple working conditions

Abstract

The invention provides a transient hydraulic system capable of being adjusted under multiple working conditions. The transient hydraulic system comprises a frequency conversion controller, a motor, a hydraulic cabin and a water pump unit. The water pump unit is arranged in the hydraulic cabin, a pump shaft of the water pump unit penetrates through the wall of the hydraulic cabin and then is connected with the motor through a coupling, and the frequency conversion controller is arranged on the motor. The water pump transient hydraulic system is set up, transient starting and suspension of the system are controlled by the frequency conversion controller, the working conditions set by the system are achieved, multi-working-condition adjustment is achieved, and the transient hydraulic system is suitable for different hydraulic impeller conditions.

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...

Problems solved by technology

The Chinese patent application number is 201210376589.6, and the name is "hydraulic water pump unit". It proposes a hydraulic water pump unit to solve the problems of limited use and low work efficiency of the existing water pump. The hydraulic unit includes a movable frame, The water pump, winding mechanism and power mechanism are equipped with a hydraulic motor, which converts mechanical energy into hydraulic energy, and then drives the water pump to work through hydraulic energy

Chinese patent application number 201420204751.0, titled "Multifunctional Hydraulic Water Pump for Oilfield Workover Operations", provides a multifunctional hydraulic pump consisting of a hydraulic motor, hydraulic reversing valve, submerged sewage pump, guard, filter and hose Water pump, the hydraulic system is mainly used in oil fields, and its application range is limited; the hydraulic system lacks effective control parts, and it is a stable working condition

The above two technical solutions are simply limited to general conventional hydraulic systems, lack of transient control systems and structures suitable for multiple working conditions, and cannot meet the operating efficiency and reliability requirements of hydraulic systems under specific conditions
