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. Install the instrument as shown in Fig.1.
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.
1. GD-12579 Foaming Characteristics 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. GD-12579 Foaming Characteristics Tester equips an automatic timing alarm.
