LFY-217B Watertight Test Apparatus for Fabrics (Electric Version)

Patent of the State  Patent Number: ZL 97 2 44928.0
 

Main Application
The LFY-217B electric static water pressure tester is used to measure the water resistance of tight fabrics, such as canvas, oilcloth, felt, tent fabric, rainproof clothing fabric, and medical protective clothing materials. When one side of the sample is subjected to a continuously rising water pressure, the water resistance of the sample can be determined. It can also be used to measure the water resistance of other coated materials.
Main Structure
1. Sample holding disc
2. Electric metering pump for applying pressure to the sample
3. Pressure rate control section
4. Pressure display
Instrument Features
1. The instrument uses an electric metering pump pressure application device to apply pressure to the sample.
2. The pressure rate is controlled by a single-chip microcomputer.
3. The pressurizing medium used: water or non-corrosive liquid.
4. The specially designed sample holder ensures a firm grip on the sample. Technical indicators
1. Pressure range and measurement accuracy: 0 - 200 kPa, accuracy 0.1%
2. Pressure increase rate: 1.0 kPa/min and 6.0 kPa/min are selectable.
3. Sample size: Φ125mm, pressure-bearing area: 100 cm² circle
4. Power supply: AC 220V, 50Hz, 100W.
