The drainage board horizontal water flow tester is a testing instrument for testing various geosynthetics. It complies with SL / T237-1999 Geosynthetics Test Rules. Its section width is 10cm and thickness is about 5mm. This product is in accordance with the requirements of the National Building Materials Bureau quality inspection
Drain board horizontal water flow tester works:
The water in the overflow water tank is sent to the working container by the water pump, so that the container is filled with water, and the pressure pump is started to pressurize the pressure container. Transfer the pressure to the work container and make it equalize.
Drain board horizontal water flow tester features:
The working container of the drainage plate water meter is welded by a stainless steel cylinder of φ130, 2mm thick and a flange of φ200, 10mm thick, and the effective length is 40cm. An oval hole is formed in the middle of the flange plate, and the size of the hole is 120mm × 15mm. A stainless steel tray with holes is arranged flush with the bottom of the hole. A pressure gauge, a drainage port (with a valve), a pressure port (with a control valve), a water supply port (with a valve), and an overflow port (with a valve) are arranged on the working container of the type drainage plate water meter.
The inlet balanced water tank is 30cm high, and is welded into a flange with a flange through a horizontal connection section of 150mm × 40mm. The opening of the flange is the same as the flange of the pressure vessel. A water inlet is set at a height of 10 cm of the water tank. An overflow sill with a height of 25 cm (with the bottom of the water tank as the base point) is set in the water tank, and an overflow port 1 is set on the outside of the water inlet balanced water tank.
The overflow balanced water tank is 7cm high and is welded to the flange plate as a whole through a 150mm × 40mm horizontal connection. The opening of the flange is the same as the flange of the pressure vessel. An overflow sill with a height of 5 cm (with the bottom of the water tank as the base point) is set in the water tank, and an overflow port 2 is set on the outside of the overflow balance water tank.
Technical parameters of drainage board horizontal water flow tester:
★ Test size: 100mm * 450mm
★ Power supply voltage: 380v

Drain board horizontal water flow tester operating procedures:
★ Installation sample
The test piece was cut into a sample of about 48 cm in length, the filter membranes at both ends were removed by 1 cm, the 4 corners of the test piece were cut into 45 ° chamfers, and carefully inserted into the tubular latex film.
The drainage plate and the latex film are fed into the container through the opening of the working container, and sent out from the other opening along the supporting plate, so that the exposed length at both ends of the flange is about 4cm.
Cover the exposed part of the drainage board with rubber guides, make the rubber pads close to the outside of the flange, and wrap the latex film on the rubber pads. The other two rubber pads respectively cover the remaining exposed parts of the drainage board, so that the inverted part of the latex film is centered on the rubber pad. The membrane of the drainage plate should extend beyond the rubber pad.
Fix the inlet balance water tank and overflow balance tank with 4 screws to the working container, and tighten the screws evenly
★ Passing water
Open the water supply pump and the inlet valve 3 to fill the inlet balance tank with water through the inlet, so that there is water flowing out of the overflow port 2 of the overflow balance tank for a period of time, so that the air in the drainage plate and the filter membrane are fully wetted. . Then close the water inlet valve 3.
Open the drain and water supply valve of the working container, turn on the water pump switch, and enter the water through the water supply port. When there is water flowing out of the water discharge port, close the water inlet drain port, open the pressure pump switch, and pressurize to the required pressure with the pressure pump Automatic stop
