LFY-244 Filtration Tester
The main purpose
It is suitable for the determination of the water drainage of polyester forming fabrics and drying fabrics for papermaking.
Principle of Measurement
Adjust the water pressure to 1500Pa, make the water flow into the water tank through the overflow pipe, open the baffle while timing, depending on the time required for the water to fill a container of a specific capacity, and then convert it to equivalent 5l of water flowing through the ￠20mm net (papermaking surface Above) time, that is water filtration performance, s/5l.
Technical index
1. Medium: purified tap water;
2. Water pressure: 1500Pa;
3. Water temperature: (20±2)℃;
4. Sample size: ￠25mm;
5. Timer accuracy: 0.01s.
Applicable standards
