Embodiment
Continuous condensate water damp heat test instrument as shown in Figures 1 to 6, comprises container, temperature-controlled member and heater block 6.
Container comprises the container cover 1 being positioned at top and the tank 2 being positioned at bottom, and container cover 1 and tank 2 seamless link, define the cavity that is held gas above tank 2, below container cover 1.Container cover 1 offers and inserts groove 3 for what put into coating test plate (panel) 4, insert groove 3 and lead to tank 2 by cavity, after coating test plate (panel) 4 loads and inserts groove 3, one side end face is towards in the cavity of container.
With reference to figure 3 and Fig. 5, described temperature-controlled member at least comprises the temp probe 5 being arranged on and inserting below groove 3, and temp probe 5 is positioned at the top of the highest liquid level of tank 2 and does not steep in water, for detecting the temperature of empty intracavity gas.In general, temp probe 5 is about 20-30mm lower than inserting groove 3 extreme lower position.The determination of the highest liquid level of tank 2 can have various ways, such as in tank 2, arrange high fluid level scale line, again such as, arranges run-down pipe in tank 2, the mouth of pipe position of run-down pipe and the highest liquid level of tank 2.
With reference to figure 3 to Fig. 5, described heater block 6, is arranged on bottom tank 2, the water contained in tank 2 can be heated, thus formation water vapour, water vapour can in the condensation of coating test plate (panel) 4 inner side end after rising afterwards, and the temperature of water vapour monitored by temp probe 5.This heater block 6 can be generally heat-generating pipe, and its end is connected on the wall of tank 2, connects the wire of energising and control signal from tank 2 outside.
Described temperature-controlled member and heater block 6 are electrically connected, and temperature-controlled member adjusts the heating situation of heater block 6 according to temperature.Such as, in cavity, vapor (steam) temperature need control at 36-40 DEG C, and when vapor (steam) temperature is lower than 36 DEG C, start the power of heater block 6 or raising heater block 6, so the output of steam increases, the corresponding raising of vapor (steam) temperature in cavity; If vapor (steam) temperature is higher than 40 DEG C, close down the power of heater block 6 or attenuating heater block 6, so the generation of steam reduces, the corresponding reduction of gas temperature in cavity.In this way, can the vapor (steam) temperature of strict Control experiment instrument internal cavity, thus the accuracy of continuous condensed environment in warranty test, the accuracy of test plate (panel) anti-moisture test result of guaranteeing to paint.
As further preferred embodiment, this test instrument also includes Liquid level parts, is in suitable value for the water level controlled in tank 2.The bottom of tank 2 is provided with freeing port and water inlet, and freeing port is connected to drainpipe 7, and the entrance of drainpipe 7 is roughly concordant with tank 2 bottom, and outlet is drawn outside tank 2.Water inlet is connected to water inlet pipe 8, and the entrance of water inlet pipe 8 is preferably higher than the highest liquid level of tank 2, and outlet is drawn outside tank 2.Described Liquid level parts comprise the liquid-level probe (not illustrating in figure) of liquid level in monitoring tank 2, are arranged on the electrically operated valve (not illustrating in figure) of drainpipe 7, water inlet pipe 8 respectively.Liquid-level probe and two electrically operated valves all can be controlled by the controller of outside, and such as, when liquid-level probe to detect in tank 2 that liquid level is not enough, the electrically operated valve of water inlet pipe 8 is opened into water, until liquid level reaches setting value and closes by corresponding electrically operated valve in tank 2.Otherwise when liquid-level probe detects that in tank 2, liquid level is too high, the electrically operated valve of drainpipe 7 opens water outlet, until corresponding electrically operated valve is closed after in tank 2, liquid level reaches setting value.The structure of this automatic liquid level control and automatic water supplement avoids lack of water in tank 2 on the one hand, makes under suitable level on the other hand, and the value fluctuation that temp probe 5 detects is not too large, makes regulation and control more accurate.
As further preferred embodiment, this test instrument also comprises the time controling parts that Control experiment instrument runs duration.Time controling parts and temperature-controlled member, heater block 6 are electrically connected, and by setting suitable time value, making test instrument synchronous averaging, auto stop, ensure that the synchronism of test duration.
Referring to figs. 1 to Fig. 3, wherein temperature-controlled member also comprises the temperature control panel 10 be arranged in container cover 1, can handled easily, the built-in temperature control controller 11 of temperature control panel 10.Time controling parts comprise the time controling panel 9 be arranged in container cover 1, same handled easily, and the core component of this time controling panel 9 is the time relay 12.
The electrical schematic diagram of temperature-controlled member, heater block and time control assembly is provided in Fig. 6.Its principle of work is: the time relay 12 electric and in the time range being in setting time, triggering temperature control controller 11 and temp probe 5 work, temp probe 5 by the temperature feedback in container cavity to temperature control controller 11, when temperature value reaches low level predetermined value, relay 13 conducting, thus make heating tube (heater block 6) energising start heating; When temperature value attains to a high place predetermined value, relay 13 disconnects, and heating tube dead electricity stops heating.If test instrument has exceeded the setting value of the time relay 12 working time, then the time relay 12 has disconnected, and temperature control controller 11, temp probe 5 be dead electricity simultaneously, and relay 13 disconnects, and heating tube dead electricity stops heating.
As further preferred embodiment, container cover 1 is roughly in trapezoidal, there are a top end face and two inclined-planes, to insert on two inclined-planes that groove 3 is arranged on container cover 1 and the angle of the plane and surface level of inserting groove 3 place is 30 °-75 °, be preferably 60 ± 5 °, being convenient to condensate water returns in tank 2, reduces water body and runs off.
The above is the preferred embodiment of the present invention, and it does not form limiting the scope of the invention.
