Liquid Rubber bet irrigation water hydraulic hydraulic test Operational Details

Liquid Rubber bet especially for water drainage system and sub- stratified horizontal pipe riser hydraulic test rigor , but also for sanitary ware and floor drain rigor hydraulic test . Hydraulic test should be used for special plugging inflators , airbag shutoff specifications shall be hydraulically tested pipeline facilities. Hydraulic test procedures as follows:
( 1 ) Preparation: First inflator Hydraulic hose fittings of accessories for leak testing and inspection tool . The balloon is placed in a bucket filled with water and hold a pump to the air bag inflates , check the air bags, hoses , and interface leaks , gauges without instructions.
( 2 ) with a tape measure from the mouth to the floor riser inspection horizontal tube below the minimum vertical distance and extended 500 mm ( length 2m), remember this length and this length  Hydraulic pipe fittings is marked on the hose connected to the airbag and airbag on , make mark to control the balloon inserted into the riser depth.
( 3 ) open riser inspection port , the balloon slowly from the mouth down into to the desired length, then the air bag inflates , observe the pressure gauge value , the pointer rises to 0.08 ~ 0.1MPa appropriate, the airbag in close contact with the tube wall Tuen water did not leak for the degree. If the inspection port is designed to install a spacer layer , the riser is not set checkpoints floors irrigation pipe hydraulic test , the airbag should be checked from the lower riser up into the mouth of approximately 0.5m, operating personnel in the lower inflation , the upper irrigation . Note that the airbag should be avoided on the stand pipe pieces joints because the site wall seams , affecting water shutoff rigor. For cast iron pipes , requiring sand clean, smooth wall , not allowed to have glitches, otherwise it will affect the water shutoff seal, even punctured balloon .
( 4 ) in the floor of the irrigation port ( You can also check the mouth ) irrigation -to-floor height, and then on the irrigation pipes and pipe fittings interfaces each inspection , if found tainted point , make a mark , drainage repair after treatment ; such as liquid rubber ring flexible interface , the interface can be leak tight bolt restoration with water . Such as irrigation pipeline inspection without a leakage point, the water level can stabilize the irrigation time duration 15 minutes , keeping five minutes irrigation level does not drop as qualified.
( 5 ) the balloon deflated , and then slowly pull out the capsule , be careful not to damage the capsule .
( 6 ) Remove the airbag , the water should be able to quickly drain away , such as falling very slowly , indicating that irrigation pipe clogged with debris , should be cleaned up.
( 7 ) with the balloon inflated method can also check for leaks squat stool . Placed in the bladder outlet squat stool and inflated , and then squat stool inside irrigation ( water level toilet along ) , if the water level dropped , indicating a leak rinse water interface , or squat stool water interfaces closed lax, or squat stool leakage itself , should be directed excluded .
( 8 ) irrigation hydraulic test should partition segment ( layer ) for the hydraulic test results should be recorded .
( 9 ) buried pipeline irrigation hydraulic test method is basically the same
GB GB50242-2002 Section 5.3.1 states: storm sewer installation, hydraulic testing should be done irrigation , irrigation height must be to the top of each riser funnel rainwater . Mainly in order to ensure the quality of the project , because rainwater pipes are sometimes full pipe flow , to have a certain bearing capacity .
