Description

Technical Field

[0001] This utility model relates to the field of lubricating oil purification technology, specifically a PLC-controlled integrated device for lubricating oil film stripping, dehydration, and fine filtration. Background Technology

[0002] During use, lubricating oil is inevitably contaminated by moisture, dust, or metal abrasive particles. Under conditions of high temperature, moisture, and high pressure, lubricating oil will form a varnish film, which is a highly polar molecular hydrocarbon polymer. This will affect the lubrication effect, increase equipment friction, cause valve blockage and equipment wear, and ultimately increase the maintenance cost of mechanical equipment.

[0003] Existing purification equipment is generally a single-function purification device. Modules such as paint film removal, dehydration, and filtration operate independently, occupying a large space and having complex pipelines. Maintenance and management are also quite cumbersome. Traditional dehydration technology has extremely low stripping efficiency, and traditional devices rely on manual monitoring, making real-time adjustments impossible and resulting in poor flexibility.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1 As shown, this utility model provides a technical solution: a PLC-controlled integrated equipment for stripping, dehydrating, and finely filtering lubricating paint film, including an oil tank 1. A turbine flow meter 9 is connected to the right side of the oil tank 1 via a valve 2. An oil pump 8 is connected to the right side of the turbine flow meter 9 via an oil pipe. The other end of the oil pump 8 is connected to an electro-adsorption purifier 4. The other end of the electro-adsorption purifier 4 is connected to an adsorption-type dehydration purifier 5. The bottom of the adsorption-type dehydration purifier 5 is connected to a coarse filter 6 via a pipe. The coarse filter 6 is connected to the oil tank 1 via the valve 2.

[0016] Furthermore, a pressure sensor 3 is installed between the oil pump 8 and the electro-adsorption purifier 4, between the electro-adsorption purifier 4 and the adsorption dehydration purifier 5, between the adsorption dehydration purifier 5 and the coarse filter 6, and between the coarse filter 6 and the precision purifier 7.

[0017] Specifically, by installing pressure sensors 3 at various key points, pressure changes in each component can be detected in real time, ensuring that the system operates within a safe range and improving stability.

[0018] Furthermore, the bottom of the coarse filter 6 is connected to the top of the precision purifier 7 via a pipe, and the bottom of the precision purifier 7 is connected to the oil tank 1 via a pipe.

[0019] Specifically, when the moisture content of the lubricating oil detected by the online moisture monitor is less than 300 ppm, the precision purifier 7 is activated to remove small particulate mechanical impurities. When the moisture content is greater than 300 ppm, the precision purifier 7 is not activated to remove large particulate mechanical impurities and improve stability.

[0020] Furthermore, an online moisture monitor is installed inside the oil tank 1. The probe of the online moisture monitor is located below the liquid surface, and the online moisture monitor is connected to the PLC system.

[0021] Specifically, the online moisture monitor can be used in conjunction with the turbine flow meter 9 to monitor and adjust the overall flow rate in real time via a PLC.

[0022] Working principle: First, a turbine flow meter 9 is connected to the right side of oil tank 1 via valve 2. The turbine flow meter 9, in conjunction with the online moisture monitor inside oil tank 1, regulates the overall system. When the moisture content in the lubricating oil is less than 300 ppm, the precision purifier 7 is activated; when the moisture content is greater than 300 ppm, the precision purifier 7 is not activated. It is selectively activated based on the quality of the oil. Second, an electro-adsorption purifier 4 is connected to the right side of the turbine flow meter 9 via oil pump 8. This purifier can adsorb varnish and gum in the lubricating oil. The other end of the electro-adsorption purifier 4 is connected to an adsorption-type dehydration purifier 5. Similar to removing moisture from lubricating oil, the bottom of the adsorption-type dehydration purifier 5 is connected to the coarse filter 6 via a pipe. The coarse filter 6 is used to capture large particulate impurities in the oil. Finally, pressure sensors 3 are installed on the pipes between the oil pump 8 and the electro-adsorption purifier 4, the electro-adsorption purifier 4 and the adsorption-type dehydration purifier 5, the adsorption-type dehydration purifier 5 and the coarse filter 6, and the coarse filter 6 and the precision purifier 7, which can monitor the pressure between each component in real time. Valves 2 are installed at the bottom of the electro-adsorption purifier 4, the adsorption-type dehydration purifier 5, and the coarse filter 6 to ensure the stability of the system.
