2. If the low temperature fails to reach the target of the test, then you must observe the change of temperature. It is the temperature drop is very slow, or the temperature has a tendency to rebound after the temperature reaches a certain value. The former must check whether it will be before the low temperature test. After drying in the studio, the test chamber is kept dry, and then the test sample is placed in the work chamber. The test sample is placed in the work chamber. The test sample in the work chamber is placed too much, so that the air in the work chamber cannot be sufficiently circulated. After eliminating the above reasons, It is necessary to consider whether it is a fault in the refrigeration system. In this case, it is necessary to ask a manufacturer's professional to perform the repair. The latter phenomenon is caused by the poor use environment of the equipment. The ambient temperature of the equipment and the location of the equipment (the distance between the cabinet and the wall) must meet the requirements (as specified in the operating instructions of the equipment).
3. In the hot and humid test, the actual humidity will reach 100% or the actual humidity and the target humidity are very different, the value is much lower, the former phenomenon: may be caused by dry gauze on the wet ball sensor, then check the wet Whether there is water shortage in the ball sensor's water tank, the water level in the water tank is automatically controlled by a water level controller, and the water level controller water supply system checks whether the water supply is normal and whether the water level controller works normally. Another possibility is that the wet ball gauze may cause the gauze to become hard due to the long use time or the purity of the water supply, so that the gauze cannot absorb the moisture and dry, and the above phenomenon can be eliminated only by replacing or cleaning the gauze. The latter phenomenon is mainly because the humidification system is not working. Check the water supply system of the humidification system. Check whether there is a certain amount of water in the water supply system. Control whether the water level of the humidifying boiler water level is normal and whether the water level in the humidifying boiler is normal. If all of the above is normal, then check the electrical control system. This should be done by professional maintenance personnel.
4. When the equipment suddenly fails during the test operation, the control instrument displays a corresponding fault display prompt and a voice alarm. The operator can quickly check which type of fault belongs to in the troubleshooting section of the operation of the equipment, and the professional can quickly eliminate the fault to ensure the normal operation of the test. Other environmental test equipment will have other phenomena in use, it is necessary to specific phenomena, specific analysis and exclusion.
The environmental testing equipment should also be regularly maintained. The condenser of the refrigeration system should be regularly cleaned. For the moving parts, lubrication should be performed according to the instructions, and the electrical control system should be regularly maintained and inspected. These tasks are indispensable.
HDPE film is also known as high density polyethylene film, HDPE geomembrane, HDPE impermeable film, the polymer is not hygroscopic and has a good waterproof vapor.HDPE has good anti-corrosion performance, electrical performance, moistureproof performance, anti-seepage performance, high tensile strength, so it is very suitable for wire and cable, engineering seepage prevention, aquaculture seepage prevention, oil tank seepage prevention, basement seepage prevention, artificial lake seepage prevention and other fieldsHDPE film is also known as high density polyethylene film, HDPE geomembrane, HDPE impermeable film, the polymer is not hygroscopic and has a good waterproof vapor.HDPE has good anti-corrosion performance, electrical performance, moistureproof performance, anti-seepage performance, high tensile strength, so it is very suitable for wire and cable, engineering seepage prevention, aquaculture seepage prevention, oil tank seepage prevention, basement seepage prevention, artificial lake seepage prevention and other fields.
