Simulation device for hydraulic transmission characteristics of umbilical cable

Abstract

The invention discloses a device for simulating the hydraulic transmission characteristics of an umbilical cable, and the device comprises an inlet tee pipe joint, a high-pressure oil-incoming equivalent module, a low-pressure oil-incoming equivalent module and an oil-returning equivalent module, wherein the high-pressure oil-incoming equivalent module, the low-pressure oil-incoming equivalent module and the oil-returning equivalent module are connected with the connected with the inlet tee pipe joint, and each module comprises an equivalent simulation part and a non-equivalent part. The three equivalent modules are respectively provided with a control valve, and the output ends of the control valves are connected with an adjustable energy storage device, gas outgoing and incoming two-position two-way solenoid valves, a single-chip microcomputer, and a control switch of a PLC programmable control cabinet. The gas outgoing two-position two-way solenoid valve is connected with a zero pressure gas cylinder group. The gas incoming two-position two-way solenoid valve is connected with a high-pressure air cylinder group. The gas outgoing and incoming two-position two-way solenoid valves are respectively connected with output ends of stop valves on the non-equivalent parts and the other stop valve. The other stop valve is connected with a next submodule. The device can be used for replacing and simulating the hydraulic transmission characteristics of real umbilical cables with different lengths and different diameters, is convenient for adjustment, and greatly reduces the testing cost.

Description

technical field [0001] The invention relates to a transmission characteristic simulation device, in particular to an umbilical cable hydraulic transmission characteristic simulation device used in an underwater control system. It belongs to the field of marine engineering. Background technique [0002] At present, the existing underwater electro-hydraulic composite control system is mainly composed of two parts: above water and underwater. The facilities mainly include: umbilical cable, underwater umbilical cable terminal, underwater distribution unit, electro-hydraulic flying line, underwater control module, etc. The components and components of the underwater control system are important for the safe, reliable and stable operation of the entire underwater production system crucial. Therefore, it is necessary to carry out rigorous tests on the developed underwater control system in order to detect possible problems in design, manufacture and assembly early, and then impro...

Problems solved by technology

However, since the umbilical cable of the underwater production system is more than ten or tens of kilometers long, if the joint test of shallow water is applied to the umbilical cable of more than ten or tens of kilometers for testing, not only the test cost is very expensive, but also , because the parameters such as umbilical cable length and pipe diameter are fixed, so the test range is narrow, and it is impossible to test the influence of different lengths and different diameters of umbilical cables on the performance of underwater products
