Description of a Spindle Testing
.
Introduction:
After connecting the spindle to the computerized testing system (air, electricity, control etc.), it
will automatically perform a series of tests, record the results, send notice when the test fails and
stop in case of a danger. At the end of each test a detailed report is received including diagrams.
• The operator can change the numeric definitions for the operating process.
• Results recording will be continuous and written in data format. In case of a failure data will
be recorded for the propose of repairing the defects (faults) As well as reference and
proposals for improving.
• When a test will fail, a window will open with the name of the test blinking.
• The test report will be produced at the end of the test.
•
On the screen there will be a display of the test progress, a graphic display, and a analogy
of digital display
Connecting The Spindle To The Testing System
Identification and recording of spindle (serial number, bar code, or any other ID code).
-Fixture spindle.
-Connect air tube.
-Connect power cable.
1. Testing Seal Of Coolant System
Testing seal of engine coolant system by measuring air pressure decline as a time function
(Bar/min). With air manometer at zero rpm.
2. Testing Engine Coolant Flow
Testing coolant flow to engine (lpm), with air manometer. At zero rpm.
3. Air Flow For Bearing
Testing airflow to spindle (lpm), with air flow meter. At zero rpm.
4. Air Flow In Rear Ventilation
Testing airflow in rear ventilation (lpm) with air flow meter. At zero rpm.
5. Engine Coils Resistance
Testing engine coil resistance (Ω). At zero rpm.
6. Thermistor Resistance
Testing Thermistor resistance (Ω). At zero rpm.
7. Deceleration
Testing deceleration time from 40Krpm to 10Krpm.
8. Vibrations
Analyze vibrations instrument.
9. Noises
Testing spindle noise using a noise meter.
10. Current
Testing engine current in 3 phases. Will show a chart of current Vs. rotation speed.
11. Voltage
Testing voltage at engine entrance in 3 phases.
12. Thermal Control Of Spindle
Reading the temperature in 3 points on the spindle including the motor thermistor. (The
thermistor is a resistor that changes according to temperature change.)
13. Continues Running
Continuous running at maximum speed (allowed), for 48 hours, during which parameters such as
speed, current, voltage, temperature etc. will be displayed and monitored, in large time intervals
according to need. The test will be based on a sample.
