Description

Technical Field

[0001] The utility model relates to the technical field of oil detection, in particular to an oil quality detection sensor with a multi-channel defoaming collection device. Background Art

[0002] In the industrial field, hydraulic oil, lubricating oil and other related oils are widely used. Moreover, as the lubrication, cooling and power transmission medium of equipment, the quality of oil is very important to the healthy operation of equipment. As the equipment is operated and used, the state of oil will change. Similarly, the state of oil can also reflect the operating status of the equipment.

[0003] In the prior art, an oil quality detection sensor is usually used to detect the oil, but such a detection method requires using an oil pump to pump the oil into the sensor, then perform the detection, and finally return the oil.

[0004] However, during the detection process, the equipment oil tank is generally not designed with an independent detection port, and it is necessary to connect to the on-site oil circuit or drill holes in the equipment to extract oil. This method of extracting oil will cause air to mix in and produce bubbles due to the unstable flow of oil in the equipment pipeline. The generation of bubbles affects the subsequent sensor monitoring results. Utility Model Content
