Detection method of high-low Temperature Test Chamber
Natural environmental standards (environmental conditions): the surrounding physical, organic chemical, and microbial standards borne by the product;
Environmental monitoring system (environmental parameters): Indicate one or more main parameters of physics, organic chemistry, and microbiology in natural environment standards;
Comprehensive experimental equipment (combined testing equipment): high-low Temperature Test Chambers that can additionally simulate two or more environmental monitoring system experiments;
Composition of experimental equipment (composite testing equipment): equipment capable of continuously simulating two or more environmental monitoring system experiments;
Tolerance value (nominal value): When testing natural environment experimental equipment, the required natural environment variable value or the natural environment variable value that needs to be determined in advance should be specified according to the experimental method;
Special load (specified load): use experimental equipment to conduct natural environment test samples;
Simulation load: the load manufactured according to the experimental standard (note: factors such as mass, geometric specifications, total frontal area, thermal conductivity, etc. should be considered);
How to solve the abnormal humidity of the constant temperature and humidity testing machine?
The first step is to check the upper storage tank for ice. If there is no water, check for ice in the lower reservoir. If there is no water in the downpipe Water Tank, the water in the lower water storage tank needs to be drained for disposal. If there is no water in the upper storage tank and the lower storage tank is frozen, the pumping motor of the lower storage tank is damaged, and the manufacturer needs to be notified immediately for on-site maintenance.
The second step is to check whether the underwater overheating protection device in the main engine room is set at 150°C; otherwise, the underwater and overheating protection device needs to be adjusted to 150°C;
The third step is to check whether the intermediate relay in the ambient humidity part is short-circuited or damaged: if the electric heater is not damaged, the AC gear of the three-purpose electric energy meter should be used, and the working voltage gear should be set to 600V. The red and black wires are marked with The rods on both sides of the intermediate relay of H are connected to each other, and then the ambient humidity preset value of the ambient humidity part is set to 0%. , kept below 10V, it means that the intermediate relay is damaged, indicating a short-circuit fault condition.
The fourth step, if there are no common faults found in the above three items, check whether the pipeline in the main engine room is too dirty, causing the water flow to be blocked; if this happens, turn on the main switch power supply after the mechanical equipment is connected, and then turn on the humidification barrel Just below the drain valve until it reaches a position parallel to the pipe. After the water in the upper water storage tank is drained, press the wrench to open the humidification barrel, remove the internal dirt and clean it, and then pull out the silicone hose. After the maintenance is completed, follow the disassembly method and reinstall in reverse. After the device is complete,
