Governor test stand is debugging, check the performance of the governor a debugging platform, is a diesel locomotive repair plant, locomotive depot, especially governor repair professional factory necessary testing equipment, in the functional, performance indicators have reached the leading domestic level, can completely replace the similar foreign equipment, to meet with various types of diesel engine governor testing requirements.

JXD combined regulator test-bed using principal deputy table structure, it can provide the subjects of various types of mechanical hydraulic speed governor in the required speed, pressure and heating oil; can also provide by governor required power signal.

Governor test stand using digital and analog control technology, can realize diesel generator system digital simulation test environment, make speed governor approximate governor and locomotive diesel engine 's actual conditions. Test bench for locomotive locomotive with QJY-5, PGEV, PGMV, 302, of combined regulator - B, C, D and other types of locomotive speed governor performance testing and commissioning test. Also apply to ships and power generation unit of mechanical hydraulic speed governor test.

Test platform design based on the one man operation, test all circuits have misoperation of protection, to prevent burning test bench.

Regulator test-bed of the main technical indicators

In 1, working voltage: AC 380V, 50HZ, 4KW;

2, test speed range : 100 ~ 1250rpm;

3, speed measuring precision: + 1 rpm;

In 4, governor output displacement measurement range, precision: 0 ~ 40mm, 0.5.

Regulator test-bed is the main performance and function

Test bench adopts the motor as the driving motor, the control system is mainly composed of a single chip microcomputer system, a displacement sensor, speed sensor, all kinds of switches and potentiometers. Displacement sensor for the detection of governor output displacement signal, speed sensor detects the speed governor signal. The two signal and adjust speed potentiometer, load potentiometer voltage signal is sent to the SCM system together, through simulation calculation, the output of a PWM control signal to the motor drive circuit to control the motor running speed. Motor connecting shaft, shaft drive through the governor to rotate together.

In the present governor test stand can be completed on the governor the following test:

In 1, the governor of the running-in test: according to the provisions of the speed governor TSP do running-in test;

In 2, the speed setting test: for each type are the highest, lowest speed governor setting;

In 3, the simulation of engine no-load speed static performance test: approximate simulation of engine no-load condition, measuring speed static volatility parameter;

In 4, the lifting speed test: can realize the 16 step speed regulation and stepless speed regulation under the condition of sudden jump, speed, speed measurement, soaring quantity fluctuation frequency and stable time;

5, uneven degree setting: simulation engine and load condition, and can be used in test bench for regulator uniformity (i.e., static adjustable rate ) for setting;

6, plus or minus load test: Simulation of sudden, dump load condition, the maximum speed of the soaring quantity measuring governor, fluctuation times and stable time;

In 7, oil pressure, oil temperature measurement: test bench can measure the governor working oil and working oil pressure ( temperature is measured through a PTC surface thermometer, oil pressure is measured by an additional pressure gauge for measuring );

In four, the running-in test
