Embodiment Construction
[0008] like figure 1 As shown, the system is composed of speed regulating handwheel E, stepless speed regulating drive device WTQ with gears, power supply and related wires, switches and so on. The 110V power line of the positive power supply is respectively connected in parallel with the input terminals of contacts A, B, C, and D to connect the outputs of contacts A, B, C, and D to the speed controller, and through the WTQ socket of the speed driver: A (1-17); B ( 1-10); C(1-12); D(1-13) are connected. Speed drive WTQ output sockets 1-16 are connected in series with stepping motor BJD socket A through resistor RW1; 1-8 are connected in series with stepping motor BJD socket B through resistor RW2; 1-18 are connected in series with stepping motor through resistor RW3 BJD socket connection; 1-6 are connected in series with the 110V positive source through the equipment power switch AN1, and 1-20 are connected with the O terminal of the stepping motor socket. Sockets 1-4 are ...

The invention is a rotation speed driving device for a speed governor and relates to a device for testing and detecting rotation speeds of all gears for a locomotive 302D speed governor. The invention mainly aims to solve the problem that an existing 302D speed governor testing and detecting device only can detect the minimum and maximum rotation speeds of a speed governor and cannot finish the detection of rotation speeds of 16 gears. According to the rotation speed driving device for the speed governor, input ends A(1-17), B(1-10), C(1-12) and D(1-13) of a speed governing locomotorium WTQ are connected with a speed governing switch K with 16 gears; output ends (1-16), (1-8) and (1-18) of the speed governing locomotorium WTQ are connected with a power input end of a stepping motor BJD respectively through resistors RW1, RW2 and RW3; and an output end (1-20) of the speed governing locomotorium WTQ is connected with the zero potential of the stepping motor BJD. According to the rotation speed driving device for the speed governor, as the switch with 16 gears is arranged on an original test bench, all gears of rotation speeds of a diesel engine of a Dongfeng 8B locomotive can be tested and detected.
Description
technical field [0001] The invention relates to a test and detection device for each gear speed of a 302D speed governor for a locomotive, in particular to a device for driving the speed of a 302D speed governor by using a joint regulator test bench. Background technique [0002] The 302D governor is installed on the Dongfeng 8B diesel locomotive. The driver controller of this model has 16 gears to control the speed of the governor in steps. The traditional combined regulator test bench can only press the "up" button for the stepping motor drive. , DOWN” button to detect the minimum and maximum speed of the governor, but it cannot complete the speed detection of the 16 gears of the 302 speed governor. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned shortcomings, and propose a governor speed drive device that can detect the speed of each gear of the 302D speed governor 16 . [0004] The technical solution of the prese...
