Problems solved by technology

Due to the limitation of the installation space of the locomotive fan, the installation position of the fan often makes it difficult for the test personnel to get close to it for accurate observation. Coupled with factors such as dim light and high-speed rotation of the fan, the test personnel often make mistakes in judging the direction of the fan during the test, thus Affected the quality of the locomotive

Embodiment Construction

[0009] The present invention will be further described below in conjunction with accompanying drawing.

[0010] Due to the different directions of the fan, the wind speed at the fan inlet is different. If the wind speed at the air inlet of the fan can be detected, it is possible to accurately judge whether the fan is turning correctly without approaching the fan.

[0011] like figure 1 As shown, the locomotive blower fan steering test device of the present invention is made up of wind speed sensor 2, telescopic rod 4, signal line 3, wind speed display 1, and wind speed sensor 2 is installed on the top of telescopic rod 4, and during locomotive test, test personnel according to location and It is necessary to detect the distance between the fans that are turning, and adjust the telescopic rod 4 so that the wind speed sensor 2 is located at the air inlet of the fan. If the air inlet wind speed of a certain fan is significantly different from the normal value, it can be judged t...

Abstract

The invention discloses a steering testing device for a locomotive fan. The steering testing device comprises a wind speed sensor and a wind speed displayer which are connected with each other by a signal wire, wherein the wind speed sensor and the wind speed displayer are fixed on a shell; the wind speed displayer is positioned at the bottom of the shell; the shell is provided with a retractable rod; the wind speed sensor is mounted on the top end of the retractable rod; and the signal wire passes through the inside of the shell to connect the wind speed sensor and the wind speed displayer, so that a tester can conveniently and correctly judge the steering of the fan without approaching the fan, thereby reducing the appearance of errors and improving the dispatch quality of a locomotive. The wind speed sensor and the wind speed displayer can be different in models, and the retractable rods can be different in forms as well, so that the steering testing device has a wide application range.

Description

technical field [0001] The invention relates to the technical field of locomotive fan control. Background technique [0002] Locomotive fans are widely used in diesel locomotives and electric locomotives to cool and ventilate traction motors, main generators and other equipment. During the locomotive test, it is necessary to check the direction of the fan to ensure that the direction of the fan is correct so as to ensure the normal operation of the electrical equipment that needs to be cooled. [0003] In the current locomotive test process, the inspection of the steering of various fans mainly depends on the visual inspection of the test personnel during the rotation of the fan. Due to the limitation of the installation space of the locomotive fan, the installation position of the fan often makes it difficult for the test personnel to get close to it for accurate observation. Coupled with factors such as dim light and high-speed rotation of the fan, the test personnel ofte...
