Application:
Geomembrane Air pressure tester is attached with geo membrane
welding machines, which used for testing welding quality. Its
working principle is when welding geo membrane central cavity
filled with air under pressure to maintain a certain period after
the gauge pointer remains unchanged weld quality is reliable. The
product is simple to operate, easy to carry, reliable detection,
especially for detection of the construction site of the geo
membrane seam quality.
Operating Steps:
(1)The test pin is stainless steel hollow needle, it will break
when improper use. So when the needle is inserted into the membrane
testing in same direction but not left and right direction so as
not to break the needle .
(2)When the temperature is below 15 ℃, the membrane turn hard not
being easily inserted. In this case, the membrane can be heated
manually by handle heater.
(3)Testing needle insertion depth depends on weld length and
time-dependent leak .At longer time; you can slowly push the needle
forwardly to ensure tightness between the needle and the membrane
to prevent leakage of needle, to ensure the successful completion
of testing.
(4)The test pin is properly connected with the air pump operation.
Note the pump connector needs into the soft tube, which pressing on
the black locker, and connecting the needle valve inside the folder
to the inflatable mouth (similar as bike inflatable) .
(5)The test needle can be determined. Method is to use your fingers
to suppress the pinhole. While testing needle being filled with
certain air, it is normal if reading of pressure gauge keep same
after a few minutes of reading the same normal.
(6)Being filled with certain air, if the pressure gauge reading
remains unchangeable for some time, then welds quality standards.
Precautions:
(1)Test pin should be properly and cleanly kept. It shall handle
carefully to avoid damage.
(2)Generally the pressure of needle is appropriate at 3/ 4 of cap,
not necessary full. The instrument should be checked regularly to
ensure the accuracy
