Characteristics of JJ2000H High Temperature Rotating Drop Interface Tensionmeter
1. The instrument has improved the pull-out method of quartz glass tubes, with a spring pin supporting the sample tube and automatically popping out when removed, making the sample tube less prone to breakage. Loading the sample before testing during injection makes it easier to clean and easier to operate. Pressure resistant, high temperature resistant, and corrosion-resistant. Loading the sample before testing during injection makes it easier to clean and easier to operate. Due to the use of stainless steel inner sleeve and stainless steel rotor, the coefficient of expansion is similar, which is conducive to temperature conduction, and the material is not easily corroded or rusted. With high concentricity, the sample tube is easier to maintain horizontal stability and less prone to shaking.
2. Equipped with an electrically controlled temperature heating system, capable of maintaining a constant experimental temperature. The instrument adopts precise PID temperature control technology, and the heating component adopts a brand new corrosion-resistant stainless steel design scheme, which has fast thermal conductivity and is easier to uniformly heat the sample tube without the need for additional temperature control equipment.
3. Upgraded servo motor control system, stable motor control; Adopting high-speed motors imported from Germany and encoder control technology imported from the United States, it has a complete servo control system and motor control system, with better upgrades and compatibility. The control speed can reach up to 14000 revolutions per minute, and the accuracy can control the speed to ± 5 revolutions per minute. The control points can reach up to 500 points, with higher accuracy and more convenient operation.
4. Adopting the latest precise LED control technology, while updating the high-speed acquisition CCD and trigger mode image acquisition, the screen does not flicker under low-speed and high-speed rotation conditions, and the interface edge imaging effect is clearer, which is conducive to analyzing the fine characteristics of oilfield turbid samples.
5. The main control program is Windows interface, easy to operate, and the images are standard BMP files that can be stored and printed. The program adopts advanced interface tension measurement calculation technology. Just press "test", and our software automatically controls the shooting speed, saves the image, calculates the interface tension value, and displays the measurement value. The process does not require manual intervention, effectively avoiding the influence of human factors on the measurement value. It can record the interface tension values that change with time, speed, and temperature, and store all measured values in the database. At the same time, it can be directly exported as an EXCEL document, and the measured value curve graph can also be displayed in real time. Humanized software design, powerful database management method to manage all test data.
6. Low noise electric imaging mechanism, interface button operation, simple and convenient. The three-point horizontal adjustment design scheme can facilitate the control of droplets within the visible window range.
