Description

Technical Field

[0001] This utility model relates to the field of oil detection technology, specifically to a comprehensive oil monitoring device. Background Technology

[0002] Fluids play a vital role in the operation of mechanical equipment, serving functions such as lubrication, cooling, and cleaning. However, the performance of fluids gradually deteriorates over time, and impurities such as moisture, particulate contaminants, and metal abrasive particles may also contaminate them. These changes can affect the performance and lifespan of mechanical equipment, and even lead to malfunctions. Therefore, real-time monitoring of fluid conditions is crucial for ensuring reliable equipment operation, optimizing maintenance plans, and reducing repair costs.

[0003] Chinese utility model CN213929012U discloses a control box for data acquisition, including a box body (1), a bracket (2) is bolted to the bottom of the box body (1), a display panel (3) and a cylindrical lock (4) are installed on the cover of the box body (1); a support plate (5) is bolted to the inside of the box body (1), a contamination sensor (6), an oil tank (7) and an oil pump (8) are bolted to the support plate (5), a moisture sensor (9) and a viscosity sensor (10) are installed on the oil tank (7), the contamination sensor (6) and the oil tank (7) are connected by a connecting pipe (11), the contamination sensor (6) and the oil pump (8) are connected by a liquid guide pipe (12), the other end of the oil tank (7) extends to the outside of the box body (1) through a drain pipe (13), and the oil pump (8) extends to the outside of the box body (1) through a liquid inlet pipe (14).

[0004] The control box used for data acquisition uses an oil pump to introduce oil into the box through the inlet pipe. The oil then passes through the contamination sensor and the oil tank, and is finally discharged through the drain pipe.

The information is displayed on the display panel, which can detect the oil contamination level, water content, and main properties of the oil in real time, and promptly determine the working condition of the oil.
