Abstract

The invention discloses an online detecting device for degree of hydraulic oil pollution, and belongs to the technical field of hydraulic transmission. The online detecting device comprises a casing installed in the oil tank, wherein the lower part of the casing is provided with an oil port communicating with the oil tank; the bottom of the casing is mounted with a pressure sensor and a sliding resistance liquid level sensor; the measuring starting point of the sliding resistance liquid level sensor is flush with the pressure sensor; the casing is further provided with a thermistor temperaturesensor internally; the pressure sensor, the sliding resistance liquid level sensor and the thermistor temperature sensor are connected with a central processing unit through an A / D conversion module,and the center processing unit is connected with a display. The online detecting device provided by the invention monitors the density of the hydraulic oil in real time by transmitting the data of the pressure sensor and the sliding resistance liquid level sensor to the central processing unit for processing to determine the pollution of the hydraulic oil, so that the user is convenient to know the degree of oil pollution in time, and the hydraulic oil can be replaced in time to reduce system failure caused by hydraulic oil pollution.

Description

technical field [0001] The invention relates to the technical field of hydraulic transmission, in particular to an online detection device for hydraulic oil pollution degree. Background technique [0002] After the hydraulic equipment has been working for a period of time, the internal wear of the hydraulic components and the immersion of external debris will cause the pollution of the hydraulic oil, resulting in a sharp increase in solid particles in the hydraulic oil. In the hydraulic system, these solid particles will aggravate the wear of hydraulic components, causing failures such as clamping and failure of hydraulic components. Therefore, it is very necessary to detect the pollution degree of the hydraulic oil. By detecting the pollution degree of the hydraulic oil, the hydraulic oil can be replaced in time to avoid damage to the hydraulic system caused by the highly polluted hydraulic oil, and to avoid premature replacement of the hydraulic oil. Waste of resources ca...
