Description

Underwater flowmeter running environment simulator
Technical field
The utility model is related to the technical fields of underwater equipment experimental technique, more particularly to the experiment skill of underwater flowmeter Art.
Background technology
Increasingly rare with land resources, global ocean resource exploitation grows to even greater heights.Compared in stage+module and using Flowmeter, the flowmeter installed under water, it is easier to realize the accurate metering of flow.The function of existing underwater environment simulator Control and record, underwater camera including pressure change in cabin are simply uncapped, and are not had still for flowmeter metering performance Test function, and outside tested device generate flow function.
Utility model content
The utility model provides a kind of simulator of underwater flowmeter running environment, can simultaneously test flow meter hold it is outer Pressure energy power, ocean current influences and metering performance, thus can more fully investigate state when flowmeter works under water.This practicality Novel technical solution is as follows:
A kind of underwater flowmeter running environment simulator, including hyperbaric chamber, pressure pump and circulating pump, which is characterized in that It is both provided with interface at the top of hyperbaric chamber and lower part, for being fixedly connected with underwater flowmeter;It is arranged in the bottom of hyperbaric chamber There is the pressure water inlet being connected with pressure pump, is provided with multiple cycle water entrances in the side of hyperbaric chamber, selects different location Cycle water entrance is connected with circulating pump, is blocked to other cycle water entrances, different directions can be generated inside hyperbaric chamber Flow.
Preferably, exhaust outlet is offered on the top of hyperbaric chamber.Pressure water inlet is provided with pressure gauge.
The utility model is provided with multiple cycle water entrances, can hold external pressure ability, ocean current by test flow meter simultaneously Influence and metering performance, thus can more fully investigate state when flowmeter works under water.

Specific implementation mode
With reference to the accompanying drawings and examples, the utility model is described in further detail.It is emphasized that following Embodiment is merely to illustrate the utility model, but is not defined to the scope of the utility model.Likewise, following embodiment is only For the utility model section Example and not all embodiments, those of ordinary skill in the art are not making creative work Under the premise of all other embodiment for being obtained, shall fall within the protection scope of the present invention.
Fig. 2 is the structural schematic diagram in one preferred embodiment mesohigh cabin of the utility model.
The preferred embodiment is used for the simulation test to underwater wet gas meter.1 appearance of hyperbaric chamber is cylinder, and inside is set There are DN50 flange-interfaces, for being connected and fixed with subject wet gas meter 2;1 top of hyperbaric chamber and bottom connect equipped with DN50 flanges Mouthful, it is connect with the checklist pipeline section of flux of moisture standard set-up;1 bottom of hyperbaric chamber is equipped with pressure water inlet 5, passes through valve, pressure Power table and pressure pump piping connection;1 top of hyperbaric chamber is equipped with exhaust outlet 6, is opened wide during suppressing the air in cabin is discharged; 1 side of hyperbaric chamber be provided with 6 cycle water entrances 7,8, will wherein 2 pass through valve, pressure gauge and water circulating pump piping connection Later, remaining 4 mouth blocks.2 cycle water entrances of selection different location can generate different directions inside hyperbaric chamber Flow 10, the working environment for simulating different directions ocean current.By flowmeter cable by cable ejector 9 draw and with meter Calculation machine connects.
The underwater wet gas meter of the present embodiment, measurement medium form are air-liquid two-phase moisture nowed forming, medium flow field Dynamic direction is bore DN50 straight up, and flowmeter includes that a set of more differential pressure long throat venturi (include long throat venturi Throttling set, pressure transmitter, differential pressure transmitter and temperature transmitter), a set of ultrasonic flowmeter (comprising sensor, pick-up Device and signal processing unit), integrating instrument, redundant manipulator and underwater cable connector, the measuring signal of flowmeter is logical with number The form of news exports, and flanged joint, design pressure 34.5MPa are used between flowmeter and upstream and downstream pipeline.
Hyperbaric chamber internal volume can accommodate measured stream gauge and can guarantee the continuity of flowmeter surrounding space, have simulation Each one of medium import and export has pressure water inlet and each one of exhaust outlet, has each three of water entrance of cycle, has anti- The cable ejector of water pressure resistance one, hyperbaric chamber design pressure are 36MPa.
Flux of moisture standard set-up, design pressure 1.6MPa, it is DN50~DN100 to be applicable in bore, and working media is sky Gas and water can generate stable gas and water two-phase flow, can provide the normal flow and loine pressure, temperature of gas and water respectively.
After experiment is ready to complete, pipe valve is suppressed, starts pressure pump, stops pressure pump when 6 spilling water of exhaust outlet, Valve is suppressed in closing;Circulating water line valve is opened, water circulating pump is started, water lines to be recycled stop water circulating pump after being full of water; To 6 water filling of exhaust outlet until overflowing again, exhaust outlet is blocked;Opening suppresses pipe valve, starts pressure pump, observes pressure gauge, Stop pressure pump needed for the arrival when pressure and close to suppress pipe valve;Start circulating pump;Start flux of moisture standard set-up Start to measure, and analysis is compared with flowmeter output information.
When off-test, stop flux of moisture standard set-up;Stop circulating pump;Pressure release discharges water and removes testing equipment.
