[0020] Example 1

[0021] like Figure 1 , Figure 2 and Figure 3The motor test chamber shown includes a horizontal base plate 100, an open chamber 101, a door 102, a viewing window 103, a fixed boss 104, a motor load 105, and a motor 800.

[0022] The open-type housing 101 has an inner bearing seat 303 on its side wall.

[0023] A transverse transition shaft 304 is provided on the open housing 101 via an inner bearing seat 303.

[0024] A sealing bushing 305 is provided on the transverse transition shaft 304 to cooperate with the open housing 101 and the inner bearing seat 303.

[0025] The transverse transition shaft 304 is respectively equipped with a first coupling 301 and a second coupling 302 for connecting to the motor load 105 and the motor 800.

[0026] The upper end face of the open-type enclosure 101 is equipped with a hot air inlet 400 and a moisture inlet 500.

[0027] A hot air inlet pipe 402 is installed on the hot air inlet 400.

[0028] Hot air inlet pipe 402 is connected to an explosion-proof hot air blower 401.

[0029] A temperature sensor 403 is installed on the hot air inlet pipe 402.

[0030] An explosion-proof exhaust fan 502 is connected to the moisture inlet 500.

[0031] The explosion-proof exhaust fan 502 is equipped with a moisture duct 503.

[0036] The working principle is as follows: Temperature sensor 403 and humidity sensor 504 monitor the temperature and humidity inside the sealed chamber formed by the open chamber 101 and the door 102, respectively, and feed the data back to the PLC controller 700 with screen display. The PLC controller 700 displays the data and controls the explosion-proof hot air blower 401 and the humidity generator 501 (start / stop) according to the preset temperature and humidity range values. At the same time, the status parameter information of the motor load 105 is also displayed through the PLC controller 700 with screen display, so that the test operator can observe the status of the motor 800 under the simulated environment.

[0037] (1) Place the motor 800 on the horizontal base plate 100 and connect it to the transverse transition shaft 304 through the second coupling 302. Start the motor 800 and drive the motor load 105 to start through the second coupling 302, the transverse transition shaft 304, and the first coupling 301.

[0038] (2) Start the explosion-proof hot air blower 401 and the humidity generator 501 respectively through the PLC controller 700 with screen display. At this time, the temperature and humidity inside the sealed box consisting of the open box 101 and the box door 102 are increased through the hot air inlet 400, the humidity inlet 500, the hot air inlet pipe 402, and the humidity duct 503 until the required test temperature and humidity values ​​are reached. The status parameters can then be observed by the PLC controller 700 with screen display fed back by the motor load 105.

In this way, after the motor 800 is fixedly installed, the two sets of support plates 600 with limiting grooves can provide horizontal auxiliary positioning for the motor 800 during the test, thereby improving the safety of the sample.
