Problems solved by technology

[0003] It is the most convenient and direct method to measure the flow rate through a flow meter, but the existing technology or scheme cannot accurately measure the volume of hydraulic oil flowing through the flow meter. There will inevitably be errors in the calculation of the total flow, which will affect the measurement and control of the flow accuracy; other solutions can also be used to improve the flow measurement accuracy in the existing technology, such as adding a control closed loop or using precision cylinders and sensors to measure the distribution of hydraulic oil flow , but this will greatly increase the complexity and cost of the system, thereby reducing the reliability and competitiveness of the system

Abstract

The invention discloses a flow accurate controlled buoyancy adjusting system. The flow accurate controlled buoyancy adjusting system comprises a supercharged oil tank, a supercharging airbag, a gear flow meter, a first safety valve, a second safety valve, a bidirectional motor pump, a control driver, a three-position three-way electromagnetic switch valve, a first oil sac, a second oil sac, a first one-way valve, a first filter, a second filter, a second one-way valve and a pressure reducing valve, wherein the supercharging airbag is arranged in the supercharged oil tank; one end of the gear flow meter is connected with the supercharged oil tank, and the other end of the gear flow meter is connected with one oil port of the bidirectional motor pump; the other oil port of the bidirectionalmotor pump is connected with two parallel pipes; and the two parallel pipes are combined to be connected with one end of the three-position three-way electromagnetic switch valve, the second end of the three-position three-way electromagnetic switch valve is connected with the second oil sac, and the third end of the three-position three-way electromagnetic switch valve is connected with the firstoil sac. The flow accurate controlled buoyancy adjusting system conducts accurate metering on flow through the flow meter so that the flow of the system can be accurately controlled.

Description

technical field [0001] The invention belongs to the technical field of ship systems, in particular to a buoyancy adjustment system with precise flow control. Background technique [0002] The buoyancy adjustment system can be used for buoyancy balance or center of gravity adjustment of underwater vehicles, etc., which can be realized by the controllable weight change or volume change of the fluid medium. The distribution control accuracy of the fluid medium affects the overall accuracy and practicability of the buoyancy adjustment system. Key points and difficult points. [0003] It is the most convenient and direct method to measure the flow rate through a flow meter, but the existing technology or scheme cannot accurately measure the volume of hydraulic oil flowing through the flow meter. There will inevitably be errors in the calculation of the total flow, which will affect the measurement and control of the flow accuracy; other solutions can also be used to improve the ...
