Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of pressure test analogue means of underwater kit, comprise Horizontal pressure tank, one end of described Horizontal pressure tank is provided with removable end socket 1, at the top of described Horizontal pressure tank, be provided with tensimeter 5, vent valve 4 and safety valve 6, in the bottom of described Horizontal pressure tank, be provided with accumulator 8, plumbing valve 9 and retaining valve 7, the outlet of described retaining valve 7 is communicated with the inner chamber of described Horizontal pressure tank, and lighting device 3 and camera head 2 are installed on the inwall of described Horizontal pressure tank.
In the present embodiment, tested underwater kit is ocean profiling observation platform or with the high pressure pump system of Yu Haiyang profiling observation platform.Vent valve 5 is for the gas in head tank is all discharged, and to simulate the hyperbaric environment of ocean, deep-sea, safety valve 6 is no more than setting value for the pressure in controlled pressure tank, plays important protective effect in applied voltage test process; Top symmetry in the main body 10 of head tank has two camera head mounting holes and lighting device mounting hole, camera seal protection shell and illuminating lamp seal protection shell are installed respectively in hole, and camera and illuminating lamp are housed respectively, for observing ocean profiling observation platform device or the motion state of high pressure pump system the record of making a video recording in head tank; Accumulator 8 is installed in the middle of the bottom part body of head tank, and the percussive action producing for relaxing sudden changes in pressure, to protect whole test macro normally to move; Accumulator 8 both sides are separately installed with plumbing valve 9 and retaining valve 7, and by plumbing valve, to water filling in head tank, retaining valve connects pressuring pump to continuing water-filling pressurization in head tank, after having tested again by plumbing valve draining release.
In the present embodiment, described vent valve 4 and described safety valve are located at the left and right sides of described tensimeter 5 for 6 minutes, described plumbing valve 9 and described retaining valve are located at the left and right sides of described accumulator 8 for 7 minutes, and described lighting device 3 and described camera head 2 are arranged in the main body 10 of described Horizontal pressure tank.But above-mentioned analogue means is not limited to the contour structures shown in figure, can be according to the needed head tank contour structures of the external form autonomous Design of ocean profiling observation platform or high pressure pump system, but must guarantee that tensimeter, vent valve and safety valve are all the time at the top of head tank, guarantee that accumulator, plumbing valve and retaining valve, pressuring pump are in the bottom of head tank.Lighting device and camera head can be arranged on suitable position on the main body of head tank or end socket as required, so that ocean profiling observation platform or high pressure pump system are carried out to all-directional illumination and shooting.
Above-mentioned analogue means can deep-sea high-pressure environment that is virtually reality like reality with testing high voltage pump or can ocean section motion platform carry out coordination and whether running status reliable and stable.
The method that adopts said apparatus to carry out underwater kit pressure test, adopts following steps:
One) tested underwater kit is put into Horizontal pressure tank, and encapsulate removable end socket 1;
Two) adopt safety valve 6 to set the required force value of test;
Three) give accumulator 8 preacceleration inflations, make its pressure reach the required force value of test, and make it have the volume change of 1L, pressure variation is no more than 2 atmospheric pressure;
Four) by plumbing valve 9, will in Horizontal pressure tank, fill with water; Concrete grammar is: first open vent valve 4, again by plumbing valve 9 to water filling in head tank, until water while starting to overflow from vent valve 4, is closed vent valve 4 and plumbing valve 9, in head tank, all fill with water, ocean profiling observation platform or high pressure pump system suspend in water.
Five) start tested underwater kit, and illuminate the environment in Horizontal pressure tank by lighting device 3, the motion state of observing tested underwater kit by camera head 2;
Six) by retaining valve 7, connect pressuring pumps, to water-filling pressurization in Horizontal pressure tank, until the numerical value that tensimeter 5 shows stops suppressing during for the required force value of test;
Seven) according to after setting-up time pressurize, by the 9 draining releases of plumbing valve, then open removable end socket 1 tested underwater kit is taken out, observe and detect compressive deformation degree and the sealing situation of tested underwater kit.
In whole applied voltage test process, top safety valve 6 plays level pressure, voltage stabilizing and safeguard protection effect, and when the hydraulic pressure in head tank is greater than the set pressure of safety valve 6, safety valve 6 is opened, unnecessary water flows out by safety valve 6, until hydraulic pressure while being reduced to setting value safety valve 6 close; Bottom accumulator 8 plays certain mitigation compression shock effect, can change and produce response fast the pressure in head tank, if hydraulic pressure is higher than accumulator 8 pressure set points, the compressed hydraulic pressure reduction causing in head tank of gas in accumulator 8, if hydraulic pressure is resisted accumulator 8 pressure set points, the gas expansion in accumulator 8 directly causes hydraulic pressure in head tank to increase, and has guaranteed that the pressure environment of ocean profiling observation platform or high pressure pump system is in steady state (SS).Mounting safety valve 6 and accumulator 8 can be simulated the motion state of tested system under deep-marine-environment better.
Although by reference to the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, can also make a lot of forms, within these all belong to protection domain of the present utility model.
