ASTM D6278 Shear Stability Tester of Polymer Containing Fluids by Diesel Injector Nozzle Apparatus

ASTM D6278 Shear Stability Tester of Polymer Containing Fluids by Diesel Injector Nozzle Apparatus

Test Standards:
ASTM D6278, SH/T0103

Product structure:

The apparatus consists of motor, coupler, gears, oxygen bomb tray, oxygen bomb, heater, temperature controller, touched LCD screen and pressure transmitter.

Application:
1.Analysis of hydraulic and gear oils used in mining and construction equipment.
2.Screening of polymers used as viscosity index improves in oils.
3.Development of predictive models using both friction torque and kinematic viscosity loss of oils.
4.Investigate accelerated oil aging in the lab (Blog)

Significance and Use:

1.This test method covers the evaluation of the shear stability of polymer-containing fluids. The test method measures the percent viscosity loss at 100°C of polymer-containing fluids when evaluated by a diesel injector apparatus procedure that uses European diesel injector test equipment. The viscosity loss reflects polymer degradation due to shear at the nozzle.
2. This test method evaluates the percent viscosity loss for polymer-containing fluids resulting from polymer degradation in the high shear nozzle device. Thermal or oxidative effects are minimized.

Product feature:

1.Original German Bosch jet pump with nozzle and atomizing chamber;

2. Bowch-type axial nozzle injector, the nozzle bracket has a filter cartridge;

3. The spherical cooler is equipped with a cooling jacket, which can effectively cool the oil sample and ensure that the temperature of the oil sample is between 30 and 35 °C;

4. The liquid flow meter controls the flow rate, digital display, 170cm3±5cm3/min;
