Rut tester operation panel
Please see below the operating panel. 2.1 power switch turn it on by pressing the power switch. Rotary switch to the right, turn the power off.
2.2 open the total power supply for the operation of the temperature control, temperature control instrument automatically into the state, according to the current temperature automatic temperature control. When heater output, the heating indicator, at the same time, the temperature control table OUT indicator, stop heating, the heating indicator light and OUT lights went OUT. This system adopts the contactless solid state relay as actuators, no action, little impact on power grid, and long service life.
2.3 hydraulic pump operation
This instrument adopts the hydraulic power source, when the hydraulic pump does not start or no pressure, ground and test load car won't start. After start the hydraulic pump, pump station pressure begins to rise, after 30 seconds, pressure can meet the requirements, can operate on ground and test car.
Note: if you open after the hydraulic pump, 30 seconds still cannot lift ground tile, it could reverse pump motor. The power input line of ABC in arbitrary 2 thread the reversing.
2.4 grinding motor performance
Press the "run" button, begin ground tile reciprocating motion, when reach the setting automatically stop after roller compaction times. If I need to stop in the process of running, press the "stop" button.
Again if you need to start the grinding operation, need to press the "reset" button on the "counter", before you can start again in watts. If you need to run over tile for operation, will the value of the counter is set to 1 second, start the "run", such as bearing car stops, the test is to place just to run over the center of the tile.
Three basic operation steps, sample molding
Step 1. Total power supply is connected.
Step 2. Set the temperature needed for temperature control table.
Step 3. Set the roller compaction times (N / 2).
Step 4. Start the hydraulic station.
Step 5. Samples to be included in the test bearing car () after the temperature reaches the set temperature, and its tight.
Step 6. Perform test load in the car to, reset the counter, set the count value is 1, press the "run" button.
Step 7. Drop ground tile, pin sample.
Step 8. Press the "run", bearing car running test.
Step 9. Reach a set number of times (N / 2), the test load car stop running automatically.
Step 10. Rising ground tile.
Step 11. Will try to turn one hundred and eighty degrees, repeat 3,5,6,7,8,9 test finished production.
Step 12. Rising ground tile, sample production is completed.
Note: N for rolling number required.
