Lubricant multilevel automatic oil and water separating system and the control method thereof

Abstract

The invention provides a lubricating oil multi-stage oil-water automatic separating system, comprising an oil-return oil tank which is serially connected to a fine sink-oil tank, a cycle oil tank, a roughing filter, a pipeline heater, a vacuum can, a fine filter, and a product oil tank; a PLC control cabinet electrically connected to the oil-return oil tank, and a return pipeline for unqualified oil arranged between the fine filter and the cycle oil tank. Simultaneously, the invention also provides a control method for the lubricating oil multi-stage oil-water automatic separating system. The invention has the advantages that the oil consumption is reduced to 50-80 barrels per month after using the separating system, and the spare cost of oil consumption is about 50-60 thousands yuan per month except power consumption and filter materials cost, the discharged polluted oil is reduced by 15 barrels per day, and the pollution degree of oil treated by water is abated, and surrounding environment is remarkably improved, additionally, the automaticity and production efficiency in production process can also be improved.

Description

technical field [0001] The invention relates to a lubricating oil multi-stage automatic oil-water separation system and a control method thereof. Background technique [0002] The limited-movement rack thin oil lubrication system is an open lubrication system, with 16 fixed oil nozzles distributed on both sides of the rack bed, spraying to the moving upper and lower support wheels and side wheels with a pressure of about 4bar. Because the stop system is close to the high-pressure water of continuous rolling, the high-pressure water is directly sprayed to the rack box, causing water, iron oxide scale, dust, graphite and other impurities to mix into the lubrication system, and impurities, cooling water, etc. are quickly mixed into the oil tank, resulting in oil Fatal pollution such as emulsification, foaming, low viscosity, and many impurities. In order to ensure the lubrication accuracy, new lubricating oil (Shell) must be replaced every day and the oil tank must be cleaned....

AI Technical Summary

Problems solved by technology

Because the stop system is close to the high-pressure water of continuous rolling, the high-pressure water is directly sprayed to the rack box, causing water, iron oxide scale, dust, graphite and other impurities to mix into the lubrication system, and impurities, cooling water, etc. are quickly mixed into the oil tank, resulting in oil Fatal pollution such as emulsification, foaming, low viscosity, and many impurities

In order to ensure the lubrication accuracy, new lubricating oil (Shell) must be replaced every day and the oil tank must be cleaned. In the lubrication system, due to the mixing of cooling water, the lubricating oil cannot be recycled, which not only causes waste of resources, but also greatly increases production costs.
