Can the third-level filtration be changed to first-level?
Thread Content
Previously, the company’s equipment used three-stage filtration for adding lubricant: 1) from the large oil tank to the small oil tank, 2) from the small oil tank to the oil pot, and 3) from the oil pot to the oil cup. The mesh sizes used were 60 mesh, 80 mesh, and 100 mesh respectively. The company is now building a new factory, and it lacks everything, so everything has been simplified – oil is simply pumped into a tank using a pump, and a 100-mesh filter screen is placed at the outlet of the tank to allow direct refueling of the equipment. The manager in charge of the equipment came to check it a couple of days ago; he kept saying that it felt awkward, but couldn’t give any reason. Does anyone think there is anything wrong with this? There are ratings for replies; thank you
No problem; the third-level filtration can be omitted as long as there are no impurities in the oil.
You can simply use a professional oil filter to add oil.
Third-level filtration: The filtration from the oil drum to the fixed tank is the first level of filtration； Fixing the fuel tank to the fuel canister provides secondary filtration ； There is three-stage filtration from the oil tank to the lubrication point. Filters for compressor oil, turbine oil, refrigerant oil, and machine oil: primary stage – 60 mesh, secondary stage – 80 mesh, tertiary stage – 100 mesh wire mesh ； For gear oil, the wire mesh screens are 40 mesh for level 1, 60 mesh for level 2, and 80 mesh for level 3. It’s not possible to generalize; in some branch factories and workshops, there are no tanks for storing oil – instead, the oil flows directly from one container to another. Therefore, the first two levels of filtration are not necessary.
In my opinion, you can definitely use a 100-mesh filter for the first stage of filtration. To put it simply, if you’re not purchasing oil in large 200-liter barrels, you can just buy 25-liter containers; you can then take them to the site and pour the oil into the fuel tank. It’s just one step of filtration, after all We have made several transfers in order to facilitate refueling operations; of course, these operations can be canceled at any time during the process. Therefore, your three-level procedures are not fixed and can be changed
Third-level filtration: The filtration from the oil drum to the fixed tank is the first level of filtration； Fixing the fuel tank to the fuel canister provides secondary filtration ； There is three-stage filtration from the oil tank to the lubrication point. Filters for compressor oil, turbine oil, refrigerant oil, and machine oil: primary stage – 60 mesh, secondary stage – 80 mesh, tertiary stage – 100 mesh wire mesh ； For gear oil, the first-stage filter uses a wire mesh with 40-mesh density, the second stage one uses 60-mesh density, and the third stage one uses 80-mesh density. As for the third-stage filters for lubricants, the Tongyi series produced by Shaoxing Shangyu Analytical Instrument Factory is quite professional; it uses 100-mesh density filters, but the mesh fabric gets clogged very quickly, which results in slow oil flow and the need to replace the mesh fabric frequently – making the efficiency extremely low. Therefore, it is recommended to use three-stage filtration. Our company continues to use Tongyi-brand third-stage filters for lubricants, and they are quite suitable for meeting the filtering requirements for lubricants.
Our unit has developed a three-stage filtration system: a filter screen with a mesh size of 60, 80, or 100 is installed at the opening of the large tank, so that the water coming out has undergone three stages of filtration
In winter, with a 100-mesh filter, it takes a day to fill up the tank with fuel – by then the daylilies have already cooled down
