First, the high and low temperature impact test box is not bright
.
I understand that when the high and low temperature impact test chamber is applied, some of the light tubes are not lit at that time, and some of them are lit up
at that time.
This is because the test chamber is generally used in electronic ballasts, and the wiring method of electronic ballasts is plug type
.
Therefore, some of the problems solved at that time due to the key points of the processing technology were not very good, which caused the safety hazards
of the lamp footline in the connection with the electronic ballast.
In the subsequent application, it may produce problems such as void disconnection and loosening
.
The second and two sides of the high and low temperature impact test chamber became black
.
This is because the test chamber port is tungsten, its melting point is 3410 ° C, when you illuminate the light tube, the temperature is 2000 to 3000 ° C in the middle, the filament is not easy to melt, will produce a rise, then the rising tungsten steam touches the wall thickness and condensed into solid tungsten, making it black, and the high and low temperature impact test chamber filament is on both sides of the light tube, so it can only be black
on both sides.
When the high and low temperature impact test chamber begins to blacken, it must be dismantled
.
Therefore, in order to increase the service life of the pipe even more, it is not necessary to start and turn off the pipe frequently
.
According to the standard, the fluorescent tube does not have to be turned off within 3 hours after the lamp is illuminated
.
Third, ultraviolet stainless steel sink rust through
.
The stainless steel sink of the test chamber is used to heat the water, simulating the natural environment
of a condenser at night in nature.
Because the stainless steel sink is processed by stainless steel, when applying machinery and equipment, if the user does not add double distillation water in accordance with the provisions to experiment, only add drinking water
.
That will cause the stainless steel sink to be eroded by the chemicals produced after the water body and the water body are heated for 3 years, causing the stainless steel sink to corrode, until the stainless steel sink and other rust penetrates
.
Fourth, the stainless steel sink heating pipe is often
dismantled.
Because double distilled water is not applied in accordance with the regulations, the heating pipe has long sexually invaded the drinking water and high-temperature drinking water
.
Everyone knows that the heating pipe is made
of stainless steel pipe filled with magnesium powder.
Therefore, long-term heating work in drinking water will cause the stainless steel plate on the surface of the heating pipe to be eroded and rust
to occur.
Fifth, the dashboard repair rate is high
.
The dashboard of the test chamber is all installed on the side of the machine and equipment, so there is a problem: when the machine and equipment carry out heating work (sometimes an experiment will be done for several days, so that for many weeks, the temperature of the laboratory can reach 60 ° C) and some laboratories are not equipped with air conditioning, and the heat flow is also upward, so the dashboard will be damaged by high temperature for a long time, and then in this high temperature natural environment, the instrument panel is very prone to abnormalities
.
