Working principle
one
Low pressure simulation
Extract air from the test chamber through a vacuum pump, reduce air pressure, and simulate a low-pressure environment at high altitude.
two
Temperature control
Adopting a compressor refrigeration and electric heating system to achieve precise temperature regulation inside the test chamber.
three
Humidity control
Adjust the humidity inside the test chamber through humidifiers and dehumidifiers.
four
Oxygen content regulation
Adjust oxygen concentration through a gas mixing system to simulate low oxygen environments at high altitudes.
five
Dynamic load simulation (for engine testing)
Simulate the load conditions of the engine during actual operation through an electric motor or hydraulic system.
Common problems and solutions
one
The air pressure cannot reach the set value
Check if the vacuum pump is working properly and if the sealing system is leaking air.
two
Unstable temperature control
Check if the refrigeration and heating systems are functioning properly, and if the sensors are calibrated.
three
Inaccurate humidity control
Check if the humidifier and dehumidifier are working properly, and if the water tank has enough water.
four
The equipment operates with loud noise
Check whether the vacuum pump, compressor and other components are installed firmly and whether lubrication is needed.
five
Control system malfunction
Restart the device, check if the PLC or touch screen is functioning properly, and contact the manufacturer for repair if necessary.
