Centralized cutting fluid supply system, oil-water separation and floating oil removal

Nantong Youteng, a manufacturer of centralized cutting fluid treatment systems, cutting fluid centralized filtration is a processing auxiliary fluid suitable for cooling and lubricating tools and workpieces during the cutting, milling and grinding processes of metal materials. It has excellent functions of cooling, lubrication, rust prevention, degreasing, cleaning and corrosion prevention. Cutting fluids are divided into oil-based cutting fluids and water-based cutting fluids. According to surveys, the demand for oil-based cutting fluids is relatively low at this stage, and water-based cutting fluids are mainly used. During the entire use process of water-based cutting fluids, the lubricating oil on the product workpieces and a large amount of machine tool guide rail oil mix with the cutting fluid. In this way, the cutting fluid mixed with various impurities and residues flows back into the cutting fluid tank through cyclic application again. The long-term cyclic use and long-term idleness of the cutting fluid cause a large amount of mixed oil to悬浮 on the surface of the cutting fluid, thereby preventing the cutting fluid from contacting the air, leading to the growth of a large number of bacteria in the cutting fluid. This not only greatly increases tool wear, but also reduces the surface accuracy of the workpiece, interferes with the working environment that is harmful to workers' physical and mental health, and causes environmental pollution problems such as air pollution, water resource pollution and land pollution. Therefore, it is necessary to purify and treat the cutting waste liquid to extend the service life of the cutting fluid.

The cutting fluid for each grinding machine in the grinding workshop of the electrode workshop is usually single-circulated. After using the cutting fluid for a period of time, the fluid will contain abrasive grains from the grinding wheel and metallic tungsten particles. When polishing the workpiece surface, these particles will cause defects and interfere with the surface quality. At the same time, the cutting fluid must be removed and replaced in time. Rough grinding requires removal and replacement every 5 days, and fine grinding requires removal and replacement every 3 days. The production cost is high and it causes environmental pollution. Therefore, large and medium-sized processing plants strongly recommend adopting the centralized filtration method. The centralized filtration system is the development trend of modern wet processing filtration. Compared with the single-machine circulation system, the advantages of centralized filtration are mainly reflected in the following aspects:

1. The filtration accuracy of the centralized cutting fluid is very easy to operate.

2. It is very easy to realize automatic control. It covers a small area, and the area occupied by large and medium-sized centralized filtration systems is much smaller than that of single-machine filtration.

3.It is convenient to manage, the number of points when adding cutting fluid is small, which can reduce the number of cutting fluid management personnel, centrally treat waste cutting fluid and reduce environmental pollution; the discharged iron chips are concentrated, which is conducive to transportation and treatment; the application of cutting fluid can conduct intensive testing.

The centralized cutting fluid supply system is suitable for the planning and construction of new factories and the renovation of old factories. It adopts integrated control and liquid circulation to solve the waste liquid problem;

Its functions include: centralized fluid supply, centralized fluid return, centralized filtration, automatic proportioning, constant pressure fluid supply, intelligent fluid replenishment, cooling and temperature reduction, concentration adjustment and monitoring, etc.;

Unified management of cutting fluids;

The centralized cutting fluid supply system project generally requires detailed docking with on-site working conditions and actual needs. It is necessary to clearly know whether the centralized purification frequency is real-time or timing, the flow rate to be achieved, site requirements, consumable requirements; as well as issues such as whether the on-site pipeline layout is overhead or underground. Generally, the centralized cutting fluid supply is not a single piece of equipment, but a complete purification system.
