Description
Technical field
The utility model relates to the membrane cartridge performance test, specifically a kind of integrity performance proving installation of folding cartridge type membrane cartridge.
Background technology
For folding cartridge type membrane cartridge, traditional integrity test is to adopt a turriform filter tank, in airtight container, install the filter core that soaks into through fully, the tensimeter of an indication usefulness is installed on the top, connect compressed gas source (generally being nitrogen) at air intake opening, the gas outlet is access in the triangular flask, observes to have or not in the bottle under the rated pressure of product regulation bubble to occur, judges whether that with this gas that takes place in the minimum bubble pressure of the filter core value scope leaks.If there is not bubble, illustrate that there is not leakage phenomenon in filter core, be complete on the whole, otherwise be exactly incomplete that the reason of generation may be that the film of filter core damages, or its end-blocking, the untight reason of banding.The requirement of two aspects is often arranged in the test practice: the one, effective and quick for guaranteeing test, at first require membrane cartridge to obtain fully apace soaking into, promptly get rid of residual air in the filter core fully, fast; The 2nd, this avoids polluting in test process as far as possible to guarantee membrane cartridge.Practice shows that because the foldable layer of filter core is piled up closely, even immersion also is difficult to make it to obtain fully to soak into for a long time, so it is more suitable in soak into operation under the dynamic pressure washing condition.
Technology contents
To realize how easily the dynamic pressure of membrane cartridge is soaked into and the integrity test problem in order solving, to the utility model proposes a kind of two combine into one, structure technology scheme that function is complete.
Membrane cartridge integrity tester of the present utility model comprises the turriform filter tank, the barrier film rain glass, vent valve, draft tube, gas outlet, gas bleed valve, triangular flask is that the jar chamber that tested filter core is used is set in jar, constitute the vapour-pressure type leak-checking apparatus, it is characterized in that said vapour-pressure type leak-checking apparatus double as is a pressure flow circulation infiltration apparatus, its gas admittance valve is a T-valve, air water is dual-purpose, or establish a water intaking valve in addition, and air intake opening connects source of the gas, and water inlet is access to water pump; Its vent valve is the dual-purpose T-valve of air water, or establishes an outlet valve in addition, and exhausr port connects triangular flask, and water delivering orifice directly inserts water tank; Water pump is located at the outside of water tank, its water inlet water receiving case bottom.
Described air inlet pipe end also is provided with air strainer.
Also be provided with air strainer on the described water tank.
Described triangular flask is provided with water delivering orifice and takes over and directly feeds water tank.
This membrane cartridge integrity tester has the following advantages:
1, realizes clamping of preparation, testing of membrane cartridge, finish continuously, make the reliability of work more secure.
2, be provided with little water tank and power pump, be convenient to soak into effective utilization of work water, accomplish using water wisely, its water generally all adopts distilled water or pure water.
3, because of this device belongs to totally enclosed circulated filter system, it is recycling only to use less water to finish, and therefore helps the cleaning of recirculated water and reduces the chance of polluting.
Description of drawings
Fig. 1 is the structure principle chart of traditional typical pick-up unit.
Fig. 2 is a structural representation of the present utility model.
Embodiment
Below describe by the embodiment accompanying drawing that provides:
As shown in Figure 1, 2, Fig. 1 is a device that is used for membrane cartridge is done bubble platen press test completeness merely.Fig. 2 is the equipment that the membrane cartridge pressure flow soaks into and steep platen press integrity test dual-purpose.
The membrane cartridge integrity tester of present embodiment, comprise turriform filter tank 1, barrier film rain glass 2, vent valve 3, draft tube 6, gas outlet 7, triangular flask 8 is the jar chamber that tested filter core 4 usefulness are set in jar, constitute the vapour-pressure type leak-checking apparatus, it is characterized in that said vapour-pressure type leak-checking apparatus double as pressure flow circulation infiltration apparatus, its gas admittance valve 18 is a T-valve, and air water is dual-purpose, or add a water intaking valve (among the figure shown in the B dotted line) in addition, its comprehensive function is identical with T-valve, and air intake opening connects source of the gas, as the nitrogen steel cylinder.Water inlet is access to water pump 11 downwards, upwards connects a jar chamber by taking over; Its vent valve 16 is the dual-purpose T-valve of air water, or adds an outlet valve (among the figure shown in the A dotted line) in addition, and exhausr port inserts triangular flask 8, and triangular flask is based on check gas leakage, also can water flowing, and its water delivering orifice then directly inserts water tank 13; Water pump 11 is located at the outside of water tank, the 12nd, water tank wall.The water inlet of water pump is access to water tank bottom.Wherein rain glass 2 also can adopt the air pressure display device that is made of pressure transducer to replace.Two work of this tester can be provided with by the working position of set valve and obtain conversion.Air strainer 10 shown in the figure is located in the pipeline 9 from source of the gas, is used to filter air inlet.Set air strainer 15 is used for the air exchange of air port on the water tank 13.Setting out the mouth of a river 14 on the triangular flask connects pipe and directly feeds water tank.17 is to fix to use pole, the 19th, and water drain valve.
Its course of work of brief description:
1, the dynamic pressure current soak into
2, membrane cartridge integrity test
Then, open gas source valve, open gas admittance valve 5, open gas admittance valve 18 (i.e. commutation), the compressed nitrogen of source of the gas filters through air strainer 10, slowly enters a jar chamber, rain glass begins to have the pressure indication, after treating the most of reflux tank of water in jar chamber, open vent valve 16 (i.e. commutation) and still have part water to enter triangular flask 8 at that time, or through triangular flask reflux tank 13.When barrier film rain glass 2 arrives the minimum bubble point pressure value of specified this filter core, at the pipe end that feeds triangular flask, if bubble do not occur, illustrate that membrane cartridge 4 does not leak, these membrane cartridge 4 integralities are good, otherwise, under minimum bubble point pressure value, when continuous air bubbles occurring, illustrate that then this membrane cartridge is imperfect, be that integrality is poor, should not select for use.
This device can be directly and the MILLIPORE company comprehensive auto testing instrument of portable filter core (Integritest-II type) adapted of producing.It is serially connected between the pipeline 9 of source of the gas-nitrogen steel cylinder and this device air source inlet, can carries out the automatic test of membrane cartridge integrality.
