Thermostat testing device and testing method thereof

Abstract

The invention discloses a thermostat testing device and a testing method thereof. The thermostat testing device comprises a testing box body, a testing chamber is arranged in the testing box body, an inner circulation fan, a refrigerating machine and an electric heater are arranged in the testing chamber, and the inner circulation fan is fixed to the inner top face of the testing chamber. According to the invention, the working environment in a high-temperature, high-pressure and high-humidity environment can be simulated, a detection condition is provided for a thermostat which needs to work in a special environment, especially constant-temperature adjustment detection in the high-pressure environment, detection data are clear, operation is simple, and detection efficiency is high; the whole device is provided with an observation port which can be observed and operated, the internal environment of the testing chamber and the maintenance and adjustment of the testing device are facilitated, meanwhile, multiple detection placing frames are arranged, one-by-one measurement of multiple thermostats can be achieved, the measurement efficiency is higher, the internal environment of the testing chamber does not need to be adjusted, the cost is lower, and the provided method is higher in detection efficiency. The cost is lower, and detection data has comparability and is more accurate.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a thermostat testing device and a testing method thereof. Background technique [0002] A thermostat is a temperature sensing device that automatically opens or closes a circuit to keep the controlled part within a certain temperature range under normal operation, and its operating temperature is only fixed or adjustable. A thermostat is a device that directly or indirectly controls one or more heat and cold sources to maintain a desired temperature. For a thermostat to perform this function, it must have a sensing element and a converter. The sensing element measures the change in temperature and produces the desired effect on the converter. The converter converts the action from the sensitive element into an action capable of properly controlling the temperature changing device. [0003] The existing thermostat test device does not have the conditions to create a humid enviro...

AI Technical Summary

Problems solved by technology

[0003] The existing thermostat test device does not have the conditions to create a humid environment, and cannot simulate a high-pressure environment. At the same time, it can only achieve a single test. After the test is completed, the test room needs to be reset, which greatly increases economic costs and reduces test efficiency. Multiple Test samples, the test data is not accurate enough
