Common trouble shooting of high and low temperature humidity test chamber

TIME:2024-10-19View:68

The high and low temperature humidity test chamber gets rid of the characteristics of high manufacturing cost and high use cost of traditional design, and creates the maximization of use economy for customers. It adheres to the design concept of "high efficiency, energy saving, environmental protection and health", and manufactures high-performance products that meet the new characteristics of the 21st century for users. Its overall design is reasonable, It has the advantages of compact structure, small volume, light weight, low noise, safe operation, high reliability, etc, Variable valve compressor. It can save more than 30% electricity than the traditional energy countermeasure method. The high and low temperature humidity test box is widely used in the industry, such as electronics and electricians, household appliances, plastic and plastic, hardware and electrical, chemical coatings, photoelectric optical fiber, communication equipment, communication accessories, LED lighting and photoelectricity, semiconductor IC, LCD module, LCD screen display, circuit board PCB, automobile parts, computer Parts, metal plating, mold, building materials, wires and cables, etc., such as: electronic parts, automobile parts, notebook computers, computers, LED lighting products, etc. virtual climate environment test

Common faults and troubleshooting of high and low temperature humidity test chamber

1. In the high temperature test of the high and low temperature humidity test chamber, if the temperature change cannot reach the test temperature value, the electrical system can be checked and the faults can be eliminated one by one. If the temperature rises very slowly, the air circulation system should be checked to see whether the regulating baffle of the air circulation is normally opened, otherwise, Check whether the motor of air circulation operates normally. If the temperature overshoot is severe, the setting parameters of PID need to be set. If the temperature rises directly and the temperature is protected, then the controller fails, and the control instrument must be replaced

2. If the low temperature can not reach the test index, it is necessary to observe the change of temperature. Is the temperature dropping slowly, or the temperature will rise after the temperature reaches a certain value? For the former, it is necessary to check whether the workroom is dried before the low temperature test, and put the test sample into the workroom after the workroom is kept dry for further test, and whether the test sample in the workroom is placed too much, The air in the working room cannot be fully circulated. After the above reasons are eliminated, it is necessary to consider whether it is the fault in the refrigeration system. In this way, the professional personnel of the manufacturer shall be invited to carry out the maintenance. The latter phenomenon is caused by the poor use environment of the equipment. The environmental temperature and location (the distance between the box and the wall) of the equipment shall meet the requirements

3. In the damp heat test, the actual humidity will reach 100 % or the actual humidity is quite different from the target humidity, the value is much lower. The former phenomenon: it may be caused by the drying of gauze on the wet ball sensor. Then it is necessary to check whether the water in the water tank of the wet ball sensor is short of water. The water level in the water tank is automatically controlled by a water level controller, and check whether the water supply system of the water level controller is normal, Whether the water level controller works normally. Another possibility is that the wet ball gauze will harden due to the long use time or the purity of the water supply quality, which will make the gauze unable to absorb water and dry. As long as the gauze is replaced or cleaned, the above phenomena can be eliminated. If the humidification system does not work, check the water supply system of the humidification system and whether there is a certain amount of water in the water supply system, Whether the water level control of the humidification boiler is normal and whether the water level in the humidification boiler is normal
