Small-scale high-low temperature damp heat test box common problem solving

Small-scale high-low temperature damp heat test box common common hindrance clears:

1. Small-scale high-low temperature damp heat test box is commonly used in high-temperature test, such as the temperature rise can not reach the test temperature value, you can check the electrical system, one by one to remove obstacles. If the temperature rises slowly, it is necessary to inspect the wind circulation system to see if the regulation of the wind circulation damper is normal. Conversely, check whether the wind turbine operation is normal. If the temperature overshoots sharp then it is necessary to set the PID setting parameters. If the temperature rises directly and over-temperature protection is provided, then the controller is obstructed and the control instrument must be replaced.

2. Small-scale high-low temperature hot and humid test chamber Common low temperature can not reach the test index, then you have to inspect the temperature changes, the temperature drop is very slow, the temperature is still rising after the temperature to a certain value, the former will check it Whether the room is to be dried before the low-temperature test is conducted, the chambers are allowed to dry, and then the test sample is put into the chamber for further testing. Whether the experimental samples in the chamber are arranged too much, the wind in the room cannot be enriched. Cycle, after clearing the cause of the above, we must consider whether it is a hindrance in the refrigeration system, so we must ask the factory's professional staff to test. The latter's sign is caused by the poor use of equipment deployment. The conditions for setting up equipment deployment arrangements and the location of the arrangement (the distance between the cabinet and the wall) are satisfactory (in the setting of equipment deployment manipulation and utilization clarification Delineation).

3. Small-scale high-low temperature hot and humid test chamber is commonly done in the damp heat test, the actual humidity will reach 100%, the actual humidity and the target humidity are very different, the value is much lower, the former's sign: probably the wet ball sensor gauze drying Induced, it is necessary to check whether the lack of water in the wet bulb sensor tank, the water level in the tank is actively controlled by a water level controller, check whether the water level controller water supply system is normal, the water level controller thing is normal. Another possibility is that the wet ball gauze may cause the gauze to be hardened due to the long use time or the purity of the water supply. This will make the gauze unable to absorb moisture and dry, as long as the gauze is replaced or washed to remove the above signs. The latter's signs are mainly related to the humidification system, inspection of the water supply system of the humidification system, whether there is a certain amount of water in the water supply system, whether the water level control of the humidifier boiler level is normal, and whether the water level in the humidifier boiler is normal. If all of the above are normal, it is necessary to check the electrical control system, which requires professional maintenance staff to conduct inspections.

4. When a small-scale high-low-temperature damp-heat test box is frequently deployed and the equipment is deployed in the course of test operation, a sudden obstruction occurs, and a corresponding impedimental performance prompt appears on the control instrument and a voice alarm prompt is issued. The operating staff can compare the types of obstacles that can be quickly detected in the obstruction removal of the operational deployment of the equipment deployment and can ask the professional staff to quickly clear the obstruction so as to ensure the normal conduct of the trial.

In other cases, there will be other signs in the test setup and equipment deployment in the use. It should be characterized, elaborated and cleared. The situation trials and equipment deployment must be carried out regularly to maintain the nursed back to health. The condensers of the refrigeration system should be regularly cleared, and the moving parts should be lubricated according to the clarifications. The small-sized high-low temperature damp heat test chambers should be regularly maintained and checked by the common electrical control systems. These matters are necessary. Nothing less.
