Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil measurement, in particular to a hydraulic oil viscosity measuring device. Background Art

[0002] Hydraulic oil is the hydraulic medium used in hydraulic systems that utilize liquid pressure energy. The performance of hydraulic systems depends to a large extent on the viscosity characteristics of the hydraulic oil. Among them, the hydraulic oil viscosity measuring device is a device used to measure the flow resistance of hydraulic oil at different temperatures. It helps to evaluate the performance and applicability of hydraulic oil. However, the existing hydraulic oil viscosity measuring device has the problem of being unable to directly stir and filter the hydraulic oil during use, and it is inconvenient to adjust the measuring temperature.

[0003] In order to address the above problems, a Chinese patent with an existing announcement number of CN219915268U proposes a high-viscosity hydraulic oil viscosity measuring device, which drives a stirring shaft to rotate through a driving motor. The stirring shaft fully stirs the hydraulic oil until there is no sediment, and then the hydraulic oil enters the measuring box from the discharge pipe. The filter net inside the measuring box can filter the hydraulic oil again. After the hydraulic oil enters the measuring box, the heating pipe inside the measuring box can adjust the temperature inside the box, thereby detecting the viscosity of the hydraulic oil at different temperatures.

[0004] However, although the above-mentioned high-viscosity hydraulic oil viscosity measuring device can stir and screen the hydraulic oil through the stirring shaft and the filter respectively, and then control the temperature inside the measuring box through the heating pipe, thereby improving the efficiency of hydraulic oil measurement, but in the high-viscosity hydraulic oil viscosity measuring device, after the hydraulic oil in the measuring box is measured and discharged, part of the hydraulic oil will remain on the inner wall of the measuring box, thereby affecting the next measurement result. Therefore, the utility model provides a hydraulic oil viscosity measuring device to meet the demand. Utility Model Content
