Explain the important maintenance points of the special components of the environmental testing equipment?
The environmental test chamber is a scientific and technological method to simulate the natural environment and climate, and it is destructive to modern industrial products. The representative test of the environmental test chamber includes: high and low temperature test chamber, constant temperature and humidity test chamber, xenon lamp aging test chamber, and ultraviolet acceleration. Weathering test chamber, thermal shock test chamber, rain test, moisture proof test, salt spray test, sand dust test, etc. In order to test the accuracy, usually the requirements for the environment are relatively high, which requires us to perform routine maintenance in addition to the correct use of the test box to ensure the accuracy of the environment and the accuracy of the test data. .
1. The price of the environmental test box is generally higher than the price of the conventional test machine according to its characteristics. In order to save costs and improve the service life of the product, the use environment of the test box should be strictly carried out according to requirements (8 ° C ~ 23 ° C). If the natural environment does not have this condition, manually control the temperature to maintain it within the standard temperature (eg, equipped with an appropriate air conditioner (air-cooled), cooling tower (water-cooled)).
Second, in terms of human factors, the instrument manufacturers that are usually purchased will go to the factory to conduct training-level safety training, etc. The operators must be carefully trained to obtain more professional maintenance and repair experience and capabilities.
Third, the test box has strict temperature requirements, so the condenser should be cleaned regularly to prevent temperature drop or poor temperature rise. The general period is every 3 months.
4. For compressors adopting air-cooled cooling mode, the condenser fan should be inspected regularly to decontaminate and remove dust to ensure good ventilation and heat transfer performance.
5. For the compressor with water-cooled cooling method, the water pressure should be guaranteed. The inlet water temperature should reach the standard value and the water flow should be appropriate. It should not be too much or too little, and often decontamination and dust removal to ensure continuous heat transfer performance.
6. Evaporation (dehumidification) should be cleaned once every three months. If it is used frequently, the number of cleanings can be increased. In addition, the cleanliness required for each sample is different. Because of forced air circulation, dust particles will be condensed and should be cleaned regularly.
7. Due to the different working environment of the environmental test chamber, a large number of small particles such as dust will be condensed on the circulating fan and condenser fan. To ensure the environment is clean, it should be cleaned regularly.
8. The water path is not smooth, and the humidifier is fouled, which may cause the humidifier to damage the humidifier due to lack of water. Therefore, it is necessary to clean the water channel and the humidifier.
IX. After the end of the test, in order to prevent damage to the test box caused by excessive temperature difference, the temperature of the test chamber shall be set to the ambient temperature. After about 30 minutes, the power supply shall be cut off and the test chamber shall be cleaned regularly.
10. If the test box is not suitable for a long time, it should be energized frequently. Usually, it is powered once every half month and the power-on time is not less than one hour.
11. When the equipment is not in use, cover it with a dust cover to prevent dust from entering.
In addition to the maintenance work of the above special components, if there is a malfunction during use, please do not blindly disassemble, first consult the manufacturer to follow the instructions or directly return to the factory for repair.
Vacuum forming is a manufacturing process used to create car parts by heating a plastic sheet and then stretching it over a mold using vacuum pressure.
You may probably find the automotive industry is the most made by vacuum forming,both for comsumer and commercial vehicles,trucks, and buses.Usually the vacuum forming car parts contain:Front bumper, rear bumper, ceiling, roof luggage compartment, wheel arches, doors, tailgate padding, dashboard, fenders, car logo, and interior and exterior plastic decorations.
In addition, the plastic trays which are used for the transportation of the engine block and cylinder also was made by vacuum forming.
