Description
Technical field
The utility model relates to a kind of salt water vat, particularly relates to a kind of salt water vat that is used for the marine generator test.
Background technology
At present, all kinds of shipyards test salt water vats that marine generator adopted mainly are that the water surface is static relatively, and the pole plate lifting changes the mode of generator load by the contact area that changes the pole plate and the water surface.Wherein, the lifting of pole plate divides wire rope to hang again and the worm and gear dual mode.Because the adjusting to salt water vat is more frequent in process of the test, very easily causes the mechanical fault of gear train and the electric fault of control loop, owing to water consumption in the process of the test is bigger, need artificial recharge midway simultaneously.
Some coastal shipyards have adopted that pole plate is fixed, the mode of recirculated water by the variable output pump change work water surface, this method has effectively solved the problem of heat radiation and gear train, but need the relatively stable seawater of a large amount of salinities, this can not realize in the shipyard of inland river.
The producer that produces generator then generally adopts the salt water vat of One's name is legion, add the mode of circulation fresh water cooling, it is more steady that this mode is regulated duty ratio, but the place that need take is bigger, also need special cooling infrastructure, under shipyard especially harbour space condition of limited, also can not accomplish.
Manual mode is generally adopted in the adjusting of salt water vat, because water evaporates is very fast, regulates more frequent.Once had school to adopt operational amplifier to add solid-state relay salt water vat is automatically adjusted, but the capacity of the salt water vat of controlling is less, its setting means is for adding adjustable resistance simultaneously, and this mode only is applicable to the laboratory, uses for reality, has little significance.
The utility model content
The purpose of this utility model is to provide a kind of salt water vat that is used for the marine generator test.
The purpose of this utility model is achieved by the following technical programs:
The salt water vat that is used for the marine generator test of the present utility model, it comprises the work water vat, be positioned at the pole plate of work water vat, pole plate and salt solution contact area control device, it is characterized in that: described pole plate comprises the deposit water vat and is connected water pipe with salt solution contact area control device, have moisturizing hole, air admission hole and vent hole on the described deposit water vat, one solenoid valve is installed on each hole, and the deposit water vat is communicated with the bottom of work water vat by connecting water pipe.
Described moisturizing hole, air admission hole and vent hole are all opened above the peak level of deposit water vat.
The cylinder body of described salt water vat is the insulation cylinder body.
Pole plate in the described work water vat adopts rectangle arranged crosswise mode.
The pole plate of work in the water vat misphase successively of arranging has been eliminated alternate load deviation effectively, makes the salt water vat space obtain maximum utilization simultaneously.
Described salt water vat is a rectangle.
Described salt water vat is provided with Programmable Logic Controller, and each solenoid valve is realized being connected by conventional solenoid valve control circuit and Programmable Logic Controller.Programmable Logic Controller is realized the automatic lifting of the actual water surface in the salt water vat according to setting electric current and detected real-time current control inflation solenoid valve, pressure-releasing electromagnetic valve and the moisturizing solenoid valve of salt water vat.
Advantage of the present utility model is: (1) salt water vat has adopted that pole plate is fixed, PLC control is filled, pressure-releasing electromagnetic valve and moisturizing solenoid valve, the operating life of solenoid valve can reach hundreds of thousands to millions of times, with respect to the pulley blocks that drives wire rope or directly drive the worm and gear of pole plate lifting, its reliability increases greatly, realized contact area automatic, quick, that stablize, adjust reliably utmost point slope and salt solution, and then the purpose of adjustment generator load.(2) quick action: the solenoid valve that quality is better, its open and close speed can remember that wire rope and worm and gear transmission are because its machinery inertial needs braking mechanism, so its advantage is very obvious with millisecond.(3) set up Programmable Logic Controller, realize that the generator test load regulates automatically: according to the generator test requirement, the adjusting salt water vat water level of fast and stable automatically, and holding power is constant automatically, and the three-phase load relative equilibrium, the adjustment error rate is less than 1%; The used on-load switch of salt water vat is according to test situation automatic closing, separating brake; Automatic water supplement in the process of the test is kept salt concentration substantially constant.
Description of drawings
Fig. 1 is the structural representation of salt water vat.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Structure as shown in Figure 1, the salt water vat that is used for the marine generator test of present embodiment, it comprises work water vat 1, be positioned at the pole plate 4 of work water vat 1, pole plate and salt solution contact area control device, described pole plate comprises deposit water vat 2 and is connected water pipe 3 with salt solution contact area control device, have moisturizing hole 5 on the described deposit water vat 2, air admission hole 6 and vent hole 7, one moisturizing solenoid valve 8 is installed on the moisturizing hole 5, one inflation solenoid valve 9 is installed on the air admission hole 6, one pressure-releasing electromagnetic valve 10 is installed on the vent hole 7, and deposit water vat 2 is communicated with the bottom of work water vat 1 by connecting water pipe 3; Described moisturizing hole 5, air admission hole 6 and vent hole 7 are all opened above the peak level of deposit water vat 2; The cylinder body of described salt water vat is the insulation cylinder body; Pole plate 4 in the described work water vat 1 adopts rectangle arranged crosswise modes, the pole plate misphase successively of arranging; Described salt water vat is a rectangle; Described salt water vat is provided with Programmable Logic Controller 11, and each solenoid valve 8,9,10 is realized being connected with Programmable Logic Controller 11 by conventional solenoid valve control circuit.Programmable Logic Controller 11 is realized the automatic lifting of the actual water surface in the salt water vat according to setting electric current and detected real-time current control inflation solenoid valve 9, pressure-releasing electromagnetic valve 10 and the moisturizing solenoid valve 8 of salt water vat.
The adjustment process of water level is in the salt water vat: generator load begins before the test, moisturizing solenoid valve and pressure-releasing electromagnetic valve are opened simultaneously, water inlet pipe begins through entering water electromagnetic valve moisturizing in the deposit water vat, when deposit water vat water level reaches working water cylinder bottom portion, moisturizing solenoid valve and pressure-releasing electromagnetic valve are closed simultaneously, stop moisturizing.When needs increase load, the inflation solenoid valve is opened, beginning is inflated to reserve tube, the reserve tube internal gas pressure increases, and under the effect of air pressure, a part of salt solution enters in the working cylinder by connecting the water pipe bottom, when arriving the requirement load, close the inflation solenoid valve, because deposit water vat internal pressure and the interior hydraulic balance of work water vat connect water pipe and stop moisturizing in working cylinder; When needs reduce load, the pressure-releasing electromagnetic valve of reserve tube top is opened, because the water surface in the working cylinder is higher than water in the reserve tube, then the interior salt solution of working cylinder is because reserve tube is returned in the effect of gravity, the contact area of the water surface and pole plate reduces in the working cylinder, and load descends.
The utility model is not limited to above embodiment, so long as the scheme of mentioning in this instructions all can be implemented.
