You can check whether there is solidification or iron filings fence net blocking in the water tank. Generally, the water tank will be designed with iron nets to block iron filings and prevent foreign bodies from sucking into the pump. Therefore, it is necessary to confirm that the height of the iron nets should not be higher than the water surface, and the oil slick should float on the water surface without being blocked, so that the effect of oil-water separation will come out. 
Again, you need to confirm that the cutting fluid has a "strong" resistance to the chute oil, and the effect will be good, and there must be no emulsification.
 
1. Cutting fluid can be divided into synthetic and non-synthetic, and its effect is different. Try to choose which cutting fluid has better oil/water drainage resistance. The cutting fluid with better oil/water drainage resistance has the best effect, and the cutting fluid with poor oil/water drainage resistance will be similar to the phenomenon of "emulsification". If so, your oil/water separation effect will be quite poor.

• The oil slick on the surface of the cutting fluid in the water tank can't be taken out?
  You can check whether there is solidification or iron filing fence in the water tank. Generally, the water tank is designed with iron mesh to block iron filings, so as to prevent foreign objects from being sucked into the pump. When the water surface is not blocked, the effect of oil-water separation will come out.
  Then you need to confirm that the cutting fluid must have a "strong" resistance to the slide oil, and the effect will be good, and there should be no emulsification.

1. The effect of cutting fluid is different between synthetic and non-synthetic components. You can try to choose which cutting fluid has better oil/water drainage resistance. Good drainage resistance will have the best effect, while those with poor drainage resistance will be similar to "emulsification". If this is the case, your oil/water separation will be quite poor.

The density of oil is 0.8 g/ml, the density of water is 1 g/ml.

So water is denser than oil, so oil is lighter and floats on water.

The specific gravity of oil and water is different. Oil is insoluble in water. Most of the oil exists in the form of a mayfly layer in water.

But part of the oil exists in the form of dispersed oil and emulsified oil.

If the oil/water is directly discharged, it will cause serious environmental pollution. Therefore, it is necessary to separate and recycle the oil/water, which is the concrete manifestation of people's love for the earth today.

• Oil-water separator, as its name implies, is a machine that separates oil from water.
• The oil-water separator is used to filter the residual oil in the water. It is widely used in the water tank of the CNC machine tool in the industry to purify the cutting fluid and avoid the heat generated during the processing of the parts. The processor inhales the lungs and causes occupational injury, and the water in the sink can be purified to high quality. Enhance the cutting efficiency of the tool.
• In more life applications, such as restaurants and apartments, the equipment for centralized sewage treatment is widely used.
• Through this equipment, oil and water are separated and then discharged to reduce the blockage of water pipes caused by oil sticking in winter.
