Product Description

ASTM D3945 Polymer-containing Oil Shear Stability Tester by a Diesel Injector Nozzle


Introduction:
The ASTM D3945 Polymer-containing Oil Shear Stability Tester is a new high-tech product developed by German technology, replacing imported instruments, all major components are purchased directly from Germany. It is suitable for shear stability determination of polymer-containing oils. The main unit consists of Bosch double piston jet pump and spray chamber with nozzle and nozzle holder. The polymer-containing oil passes through the nozzle of the diesel nozzle shear stability tester at a certain shear rate to promote the depolymerization of the polymer molecules with poor shear stability, and reduce the kinematic viscosity of the sample to report the sample. The percent drop in kinematic viscosity at the initial 100 °C is used to measure the shear stability of the polymer-containing oil.


Features:
1. Original German Bosch jet pump with nozzle and spray chamber.
2. A Bowie axial nozzle injector with a filter cartridge in the nozzle holder.
3. The spherical cooler has a cooling jacket to allow heat to pass through the wall surface.
4. The liquid flow meter controls the flow rate, digital display, 170cm³±5cm³/min.
5. The automatic stroke counter can automatically cut off the power.
6.250cm³ sump with liquid tank inlet at the top.
7. Siemens three-phase motor, power 1100W, speed 925±25r / min.
8. There is a distribution plate in the glass test tube, and a three-way piston is arranged at the cooling outlet;
9. Microcomputer temperature controller, digital display, accuracy ±1ºC, PT100 sensor.
10. Fully enclosed compressor refrigeration, large cooling capacity and low noise.
11. The digital timer records the test time with a wind alarm.
12. There is an exhaust device at the top of the jet pump.
13. There is an electronic controller for controlling the pressure on the pressure line. The digital display pressure is 17.5Mpa±0.35Mpa.
