Maintenance and maintenance of the electrical system of the high and low temperature test chamber
Because the price of the high and low temperature test chamber mainly consists of electrical, refrigeration and mechanical The system consists of. Therefore, as soon as there is a problem with the equipment, it is necessary to comprehensively check and analyze the entire equipment system. In general, the analysis and judgment process can be done from the outside in, that is, after the external factors have been ruled out first, the fundamental failure phenomenon is systematically broken down on the equipment. Finally, analyze and assess the system comprehensively or use the reverse method to find the cause of the error.
When the high and low temperature test chamber products are inside The environmental impact test Regarding the research and development of equipment, we abide by objective laws and manufacture elaborate products with strict standards.This ensures the confirmation, reliability and practicability of the equipment to produce high quality equipment for customers.For high and low temperature test chambers, Shimahan Industry generally recommends that they be at a temperature of 8 ° C to 28 ° C. Laboratories that do not have this condition must be equipped with appropriate air conditioning Adhere to special personnel for professional management and maintenance, and qualified units should from time to time special personnel for training and learning in dispatch supplier's factory to experience professional maintenance and repaireducation and skills.
Clean the condenser every three months, for the compressor is air-cooled, the condenser fan should be checked regularly, and the condenser should be decontaminated and dusted to ensure good ventilation and heat exchange performance. In the case of water-cooled compressors, in addition to ensuring the inlet water pressure and temperature, it is also necessary to ensure the appropriate flow rate and to regularly clean and descale the inside of the condenser to maintain its continuous heat exchange performance. The high and low temperature test chamber also needs to regularly clean the evaporator, because the degree of purity of the test products is different, and under the action of forced ventilation, a lot of dust and small particles will condense on the evaporator, so it should be cleaned regularly. There arealso a cleaning of the waterway and the humidifier. If the water path is not smooth and the humidifier is calcified, it will cause the humidifier to dry out and damage the humidifier. Therefore, the water path and the humidifier must be cleaned regularly. persistent in each test, after completion, set the temperature close to ambient temperature, turn off the power after about 30 minutes of work, and then clean the inner wall of the work space. If the product is not used for a long time, the product must be turned on every six months, and the turn-on time should not be less than 1 hour.
Follow the electrical schematic to find out if it one gives B. an electrical problem, and finally find out if it is a problem with the cooling system Before the UOnce the cause of the fault has been determined, do not disassemble or replace parts blindly to avoid unnecessary trouble.
