2After contact a period of time, the resistivity of pure water can descend rapidly, finally causes test figure inaccurate, does not reach the requirement of ETAG002 standard.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to operate, ultraviolet (UV) aging test chamber that reaches the ETAG002 standard-required with ultrapure water circulatory function.
For achieving the above object, the present invention adopts following technical scheme: a kind of ultraviolet (UV) aging test chamber, comprise the test water tank and be arranged at the interior test water pond of test water tank, the top of test water pond is provided with uviol lamp, the bottom of described test water tank is provided with water delivering orifice, this chamber also comprises the ultrapure circulating water device of constant temperature, and the ultrapure circulating water device of this constant temperature has the freeing port and the water inlet that links to each other with described water delivering orifice that supplies water for described test water pond; The ultrapure circulating water device of described constant temperature comprises thermostatical circulating water system and the ultrapure water system that is cascaded.
This chamber also is included as the pure water system that the ultrapure circulating water device of constant temperature provides pure water.
Described ultrapure water system is series at the place ahead of thermostatical circulating water system water delivering orifice.
This chamber also is provided with automatic control system, described automatic control system respectively with uviol lamp, the ultrapure circulating water device of constant temperature and pure water system control linkage.
Be provided with the temperature sensor of well heater, refrigerator and water temperature detection in the described test water pond, described well heater, refrigerator and temperature sensor are connected with automatic controlling system respectively.
Be provided with the resistivity measurement device in the described test water pond, this resistivity measurement device is connected with the automatic control system conduction.
Described freeing port supplies water for the test water pond by pipeline, and the water delivering orifice of pipeline is positioned at the bottom of test water pond.
Described uviol lamp has four, and four uviol lamps are square setting.
The ultraviolet (UV) aging test chamber of this scheme is provided with the circulation system of ultrapure water, after discharging in the ultrapure water system, ultrapure water directly enters in the test water pond, after having expired, ultrapure water in the test water pond spills in the test water tank, and by the test water tank bottom water delivering orifice flow back in the closed circuit, once more through purifying the back from newly flow into the test water pond, because ultrapure water is that circulation is through the test water pond, of short duration duration of contact with air, guaranteed ultrapure resistivity of water in the test water pond like this, satisfy testing requirements, met the requirement of ETAG002 standard.Because uviol lamp the time can produce a large amount of heat in work, therefore in pure water system, be provided with the thermostatical circulating water system, be used for water temperature in the Control Circulation loop, make water temperature remain on the required temperature of test always.
Ultraviolet (UV) aging test chamber of the present invention also is included as the pure water system that the ultrapure circulating water device of constant temperature provides pure water.Pure water system is connected with automatic controlling system, and when the ultrapure water in automatic control system records the tank of the ultrapure circulating water device of constant temperature was lower than need of work, just starting pure water system was the ultrapure circulating water device automatic water supplement of constant temperature.
Be provided with the temperature sensor of well heater, refrigerator and water temperature detection in the test water pond of ultraviolet (UV) aging test chamber of the present invention, temperature sensor is transferred to the signal that records in the automatic control system, make the work of automatic control system control corresponding well heater or refrigerator, be used for guaranteeing that the ultrapure water in the tank keeps the required temperature of test, simultaneously, also reduced requirement to the ultrapure water system.
In addition, in the test water pond, also be provided with the resistivity measurement device, the resistivity measurement device is transferred to the signal that records in the automatic control system, when the resistivity that records is lower than the testing requirements value, the ultrapure circulating water device of constant temperature is started working under the control of automatic control system provides ultrapure water for testing water pond, when the resistivity that records was in the scope of testing requirements value, the ultrapure circulating water device of constant temperature quit work.The requirement of ultrapure water resistivity has energy-conservation effect again in the time of can satisfying test like this, has reduced use cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
