JCB0103-2 Diesel Nozzle Tester

JCB0103-2 Diesel Nozzle TesterAccording to the current standard SH/T0130-2007, the determination of shear stability of polymer containing oil (diesel nozzle method) is carried out within the pressure range of 13.0Mpa-18.0Mpa. The reference oil (RL-34) has a kinematic viscosity loss value of 2.5mm2/s-2.85mm2/s at 100 ℃ to determine the shear stability of polymer containing oil. The European diesel nozzle tester is used to measure the kinematic viscosity loss of polymer containing oil at 100 degrees, and the viscosity loss reflects the degree of degradation of the polymer under the shear action of the nozzle. When polymer oil passes through a diesel nozzle at a certain shear rate, it will cause degradation of polymer molecules, which will lead to a decrease in the kinematic viscosity of the sample. The mechanical shear stability of polymer oil is expressed as the percentage of viscosity loss.

JCB0103-2 Diesel Nozzle TesterIt is designed and manufactured according to the requirements of SH/T0130-2007 standard for determination of polymer shear stability (diesel nozzle method), using a German Bosch dual piston jet pump and an atomization chamber with a nozzle and nozzle bracket. Has the following characteristics:

1. Bosch jet pump imported from Germany, equipped with nozzle and atomization chamber;

2. Axial nozzle injector, with a filter cartridge on the nozzle bracket;

3. The spherical cooler is equipped with a cooling jacket, allowing heat to be transferred on the surface of the jacket wall;

4. The automatic stroke counter can automatically cut off the power supply;

6. A 250ml storage tank with a liquid tank inlet at the top;

7. The jet pump is driven by a three-phase motor with a power of 1100W and a speed of 925 ± 25r/min;

8. There is a distribution plate inside the glass test tube, and a three-way piston at the cooling outlet;

9. High precision digital PID temperature controller, accuracy ± 0.1 ℃, PT100 sensor;

10. Independent fully enclosed refrigerator, using imported compressor, with large cooling capacity and low noise;

11. There is an exhaust device at the top of the jet pump;

12. There is a control valve on the pressure pipeline that controls the pressure;
