Embodiment Construction
[0034] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0035] Please refer to Figure 1 to Figure 3 , A lubricating oil quality monitoring method, including steps S10 to S90, where steps S10 to S60 are methods for monitoring the quality of lubricating oil in a lubricating oil blending plant, and steps S70 to S90 are for when adding lubricating oil to the factory machinery Lubricant quality monitoring method.
[0036] The methods for monitoring the quality of lubricants in lubricant blending plants are as follows:
[0037] S10: First, establish the temperature-dependent curve of the physical and chemical indexes of the blank base oil;
[0038] Kinematic viscosity v=f1(t+273)
[0039] Density ρ=f2(t+273)
[0040] Dielectric constant ξ=f3(t+273)
[0041] Among them, t is temperature.
[0042] S20: The sensor ...

The invention discloses a lubricating oil quality monitoring method. The method comprises the following steps: S10, a temperature-dependent curve of physical and chemical indexes of blank base oil isestablished; S20, a sensor collects temperature, viscosity, density and dielectric constant data of the base oil in the blending kettle before blending; and S30, a microcomputer screens the data acquired by the sensor, compares the screened data with the physical and chemical indexes of the blank base oil, and constructs a discrimination function and a threshold value according to the viscosity difference, the density difference and the dielectric constant difference to judge whether the base oil is polluted by the previous batch of oil products or not when being injected into the blending kettle. Correspondingly, the invention further discloses lubricating oil quality monitoring equipment. The equipment is simple in structure and convenient to implement, and more support is provided for lubricating oil filling quality control in the blending process of lubricating oil manufacturers and equipment manufacturers.
Description
Technical field [0001] The invention relates to lubricating oil, in particular to a method and equipment for monitoring the quality of lubricating oil. Background technique [0002] The production of lubricating oil is mainly a physical blending process. The blending process will make regulations on the lubricating oil blending time, blending temperature, and stirring cycle power and speed. However, the formulation of these processes often comes from experience, and occasionally problems such as insufficient blending, excessive blending time, and contamination by residual oil from the previous batch may occur. [0003] There are many kinds of additives used in the blending process, and the entrance inspection is usually based on batch inspection rather than independent packaging inspection, so there is a risk of missing the problematic additives. Lubricating oil blending tanks are usually not dedicated to special tanks due to capacity issues. Different lubricating oil sequences ne...
