Boundary Pumping Temperature Apparent Viscosity Meter -70 ～ 100℃ ASTM D3829

Product Specification

SH416 Fully automatic boundary pumping temperature apparent viscosity meter

The SH416 fully automatic boundary pumping apparent viscosity meter is designed and manufactured in accordance with the requirements of the Chinese national standard GB/T 9171-1988 Engine Oil Boundary Pumping Temperature Determination Method, as well as SH/T0562, and also meets the petrochemical industry standard ASTM D3829 D4684; An instrument used to determine the boundary pumping temperature, (low temperature) yield stress, and apparent viscosity of motor vehicle engine oil, with a wide temperature control range from -5 ℃ to -40 ℃. The entire experimental process is automatically controlled by computers.

Within 10 hours, the sample is cooled using a nonlinear program at an experimental temperature of 80 ℃ for 16 hours at a constant temperature. Then, a torque is applied on a rotary viscometer to observe and measure the rotational speed. The yield stress and apparent viscosity at this temperature are calculated, and the boundary pumping temperature of the sample is determined by three or more.

Performance characteristics

● Pumping temperature range: temperature range -5 ℃ to -40 ℃, temperature control accuracy ± 0.1 ℃

● Fully enclosed compressor refrigeration with large cooling capacity

● Temperature, cycle, and rotor movement are monitored by a microcomputer

● The instrument viscometer pool includes a numbered 9-hole viscometer in a temperature controlled aluminum block, a heater, a temperature sensor, and a photoelectric encoder. The temperature of the viscosity pool is automatically controlled by a programmable controller based on the curve selected by the user. The entire system performance is stable, and it is better than ± 0.1 ℃ in the temperature control requirement of ± 0.2 ℃ curve segment. At the end of the experiment, the data is automatically printed.

● The program automatically performs nonlinear curve temperature control, determines yield stress and apparent viscosity

● Cleaning temperature control and temperature calibration functions
