Standard requirements. It is pressurized by electric air pump and can be used by relevant departments such as scientific research, construction, production, design and teaching.

The appliance automatically controls the aeration and pressure, automatically maintains the pressure, and the digital display timing provides a very convenient device for the detection, testing and research of the impermeability of the linoleum and the waterproof membrane. The test pressure is not greater than

0.6Mpa

In this case, the instrument can be used for the determination of other materials for gas permeability or water permeability.

Second, the use of:

1

Adjust the pressure gauge according to the test requirements of the test piece before use.

The adjustment method is as follows: the adjustment knob is arranged in the middle of the glass of the pressure gauge, and the upper limit and the lower limit are adjusted, and a flat-blade screwdriver is needed. Screw the upper limit pointer to the position specified by the test, and the lower limit pointer is screwed to the lower limit

0.05Mpa

The position so that the pressure is automatically stopped when the pressure reaches the demand (upper limit value) during work. When the leakage or permeable water causes the pressure to drop to a certain value (lower limit value), the air pump automatically starts again.

Supplementary pressure

0.3Mpa

, in the middle of the case, the upper limit pointer is dialed to the dial

0.3

Position, then use a screwdriver to screw the middle lower limit pointer to

0.25

s position.

When using, first use the hexagonal wrench to loosen the pressure ring of the three permeable trays, unscrew the cover of the water inlet, and then close the drain valve, and slowly inject the water from the water inlet to the container.

Water is poured out from the water inlet hole in the middle of the drain valve, overflowing the permeable tray, and then tightening the water inlet cap.

3

Place the tested piece on the annular rubber ring of the permeable tray, place the test piece pressure plate on the tested part, and tighten the screw.

4

Set the time dialing according to the test requirements and set the time value.

5

Plug in the power plug and turn on the start switch. The air pump starts to inject pressure gas into the container, and the pressure indicator lights up.

6

When the pressure upper limit is reached, the pressure is automatically stopped. At this time, the constant pressure indicator light is on. After the test is completed according to the specified time, the water valve is opened, the water is released and the pressure is released, and then the pressure ring is released to take off the test piece, and the test is completed.
