Lubricating Oil Air Release Value Tester

Introduction:

This instrument is specially designed and manufactured according to the petrochemical industry standard "lubricating oil air release value determination”. It is used for the determination of turbine oil, hydraulic oil, and petroleum products.

The instrument is composed of circulating water bath, air oven, stainless steel cover, intelligent digital temperature control device, electric heating devices, air-way solenoid valve control, SCM automatic program operating system and others, with a heating speed, temperature effect, insulation high efficiency, long life and other features, easy and intuitive, is an ideal laboratory measuring equipment.

This instrument achieved the automatic operation, set the automatic timing system, free recording time varies depending on the test process, from beginning to do - like program control by the microcontroller to achieve a fully automated process to do sample, thereby greatly reducing the labor intensity of laboratory personnel increase the accurate reliability tests.

In order to prevent air compressor pressure used by the user is too large or no pressure limiting device, especially the addition of the instrument inside pressure limiting valve, already regulate moderate pressure at the factory.

Technical parameters

1. Input voltage: 220V ± 10% 50HZ

2. Water bath heating power: 1.3KW

3. Water bath temperature range: room temperature ~ 100 ℃, the required test temperature: 20, 50, 75 ± 5 ℃

4. Water bath temperature control accuracy: ± 1 ℃

5. Air furnace heating power: 1.2 KW

6. Air oven temperature range: room temperature ~ 100 ℃ the same temperature range with the water bath

7. Air furnace temperature control accuracy: ± 5 ℃

8. Timer function: Turn on the "time" switch, hour meter displays "00:00", press the "time" button to start the timer, press the "time" stop the clock, to keep time to 30 minutes reported hearing three seconds. In the meantime, you can freely interrupt timing. Press the "determination" button is cleared, start time, time to five minutes clearing the reported hearing three seconds, then automatically connected to the compressed air (deflated by the bypass solenoid valve is automatically converted to test ventilation), the timer automatically converted then counting to seven minutes, stop automatically pass into the air (vent closed, while the test is automatically converted to a bypass valve), clear re-clocked and reported hearing five seconds. Timed to 30 minutes and then reported hearing, then "measured" stop the clock, keeping the number recorded at this time.

9. Ambient temperature: room temperature about 25 ℃

10. Relative humidity: <85% RH
