Model: KR-HFRR80
Standard: ASTM D6079
High Frequency Reciprocating Rig Equipment Features and advantages:
1. Stroke of the testing machine: the exciter stroke/mm: 1±0.02, and can be set between 20μm-2mm; the reflective linear photoelectric encoder (grating ruler) and the reading grating sensor are used to control the stroke. During the test, the real-time stroke actual value can be observed in the software operation platform; it has a stroke self-checking system; it has a high-frequency reciprocating limit protection device.
2. The test machine can realize the lubricity evaluation of vehicle diesel, vehicle gasoline, ethanol gasoline and methanol gasoline without replacing any parts. It only needs to select the corresponding test method in the control software to carry out and test Complete the lubricity evaluation of diesel and gasoline. When evaluating the lubricity of gasoline, the operation steps for evaluating the lubricity of diesel oil are the same.
3. After the test, the freckle pictures can be directly imported into the software to form a complete test report with the freckle pictures and various parameters.
4. The microscope is equipped with a separate imaging screen and is connected with the camera of the electronic imaging system; the pixel of the microscope camera photo is 5 million. In addition, it has three sets of observation systems, such as visual microscope and electronic imaging.
5. The main box of the system testing machine and the constant temperature and humidity controller are connected in a split type to avoid resonance; the constant temperature and humidity controller is a separate instrument unit, and its characteristic is that after setting the ambient temperature and humidity, the set value can be Carry out automatic adjustment, and ensure that the temperature and humidity values in the whole test process conform to the steady-state error value of its set value.
