The RF500 dual rotary ferrograph is a new type of equipment operating condition oil analysis instrument, which meets the requirements of NB/T 51068-2017 "Iron spectrum analysis method for gear oil in coal mine oil equipment (rotary ferrograph method)" and Q-SH.J 014-2010 "Technical standard for iron spectrum analysis of coal mine equipment oil".
The RF500 dual rotary ferrograph is a new type of equipment operating condition oil analysis instrument, which meets the requirements of NB/T 51068-2017 "Iron spectrum analysis method for gear oil in coal mine oil equipment (rotary ferrograph method)" and Q-SH.J 014-2010 "Technical standard for iron spectrum analysis of coal mine equipment oil". It uses a high field gradient magnetic field to deposit ferromagnetic and paramagnetic particles generated by wear in equipment lubricating oil (or other liquid media) on a glass substrate (spectrum), and arranges them into a ferromagnetic line map according to the magnetic field force distribution. The dual rotating ferrograph adopts a dual magnetic head design, which greatly improves the spectral efficiency and tolerance to various contaminated oil samples. It is particularly suitable for qualitative and quantitative ferrographic analysis of severely contaminated oil. Then, using a ferrographic microscope, the physical characteristics such as size, shape, size, color, and surface texture of the abrasive particles can be observed, and the number of abrasive particles can be counted to identify the wear type and obtain the wear status of the equipment.
