>>> During use lubricating oils can form an undesired foam, which can greatly affect their performance. Foaming can present serious problems for system operation. The ASTM D892 foam test method is used to determine the foaming tendency and stability of foam in lubricating oils. The Foam Tester is applied to measure the foaming characteristics of lubricating oils at 24°C and 93.5°C.
>>> It is suitable to determine foaming characteristics of lubricating oil, which is used to evaluate foaming tendency and foaming stability of lubricating oil.
1. Power supply: AC 220 V±10%, 50 Hz;
2. Main heating power: 650 W;
3. Auxiliary heating power: 1000 W;
4. Refrigeration power: 500 W;
5. Flow rate of air: 94±5 ml/min, adjustable;
6. Temperature controlling range: room temperature~99.9 ºC (high temperature bath);
7. Temperature controlling range: 5~99.9 ºC (low temperature bath);
8. Temperature controlling accuracy: ±0.5 ºC;
9. Timer: 5 minutes and 10 minutes, nearest to second;
10. Timing accuracy: 0.01%+0.05 s (at 20 ºC);
11. Ambient temperature: -10ºC~+40 ºC;
12. Relative humidity: ≤85%;
13. Total power consumption: not more than 3000 W;
1. The ASTM D892 Foam Tester adopts all-in-one structure. It includes three parts: low temperature test part and it's control, high temperature test part and it's control, a portable cooler for low temperature test part.
2. The temperature controller has parameters modifying function. If there is bias between showing temperature and testing temperature,it ca be corrected by this function.
3. The ASTM D892 Foam Tester equips an automatic timing alarm.
1. Check the instrument and its accessories. If there is nothing damage or lose, please place the graduated flask containing "O" ring into the instrument and screw the locknut tightly.
2. Add water into two constant temperature baths until the water surface is higher than gap on the heater shield.
3. Turn on the power supply switch to let the instrument get power. The power supply indication light will be on and the instrument will enter into the working state.
4. Preset the required test temperature on temperature controller, and then the temperature controller will control temperature in the constant temperature baths after you turn on the instrument. The high temperature bath is equipped with auxiliary heating device, which will be cut off when the temperature is about 2 ºC near the set temperature point. The low temperature bath is equipped with special refrigeration device, which can be used as an auxiliary cooling device when the room temperature is higher than test temperature.
5. Fill sample as per GB/T12579 after the instrument enters into the constant temperature state.
6. Connect foaming head and turn on time switch, and then the instrument starts timing and the air pump begins blowing. You can adjust the flow rate of flow meter to 94±5 ml/min.
7. After blowing air for 5 minutes, the instrument will cut off the air source automatically and begin timing for 10 minutes. Then you can observe foaming tendency of lubricant oil.
