Inflatable cable pipe plugging design

Inflatable cable pipe plugging design

Inflatable cable pipe plugging design. Zhuzhou complete science and technology tailored free design program With the acceleration of urbanization, more overhead transmission lines have been relocated to the ground, underground cable ducts have been used, sediment, sewage, small animals have invaded into pipelines, and cables have run in floods and dangers. Problems such as silting and crippling of small animals have become increasingly serious.
Inflatable cable pipe plugging system is a flexible pipe plugging device consisting of polymer aluminum foil composite soft material inflatable bag, rubber reducer bushing, polymer modified rubber sealant and other parts; it is mainly used for cable pipe and cross-river Pipeline seals for roads, railway bridges, and building structures and other roads across seas and city roads can also be used as a kind of flexible pipe plugging device for waterproof plugging of different shapes and various types of pipe joints.

Inflatable cable pipe plugging system passed ten special performance tests and all qualified.
Sealing test
The product is assembled as shown in the figure below. The specimen is completely immersed in water at room temperature and the catheter is pressurized with air to 50 kPa for 15 minutes. If there is no continuous air bubble around the test piece, the phenomenon of plug shrinkage, etc., the product's tightness meets the requirements.
Axial tensile test
Install the product in the conduit and place a line in them. A load is applied to the cable shaft and the load N (D is the outside diameter of the pipe, in mm) lasts for 4 hours. During the test, the inside of the catheter was pressurized to 50 kPa. After the test results, all samples are required to pass the sealing test.
Bending test
Install the product in the conduit and place a line in them. During the test, the inside of the catheter was pressurized to 50 kPa. A bending force was applied at a position 10 times D (D is the outer diameter of the tubing) from the mouth of the catheter. The exposed tubing was bent at an angle of 45°, held and allowed to stand for 5 minutes. Repeat this operation in the opposite direction. After the test results, all samples are required to pass the sealing test.
Twist test
Install the product in the conduit and place a line in them. During the test, the inside of the catheter was pressurized to 50 kPa. A twist force N (maximum 50 N) was applied at a position 10 times D (D is the outer diameter of the tubing, a minimum distance of 250 mm) from the mouth of the catheter, held and allowed to stand for 5 minutes. Repeat this operation in the opposite direction. After the test results, all samples are required to pass the sealing test.
Vibration test
The product is mounted on a vibratory table and the pipeline is clamped at a position 10 times D (D is the outside diameter of the pipeline and a minimum distance of 250 mm) from the catheter mouth, and the sinusoidal fluctuation at the center point of the catheter is Y=6sin (20π+α) (ie, The amplitude is 6mm, the frequency is 10Hz, 0°≤α≤180°, and the duration is 240 hours. During the test, the inside of the catheter was pressurized to 50 kPa. After the test results, all samples are required to pass the sealing test.
Chemical resistance test
The product is installed in any section of a 150mm*600mm pipeline, and the entire coverage is soaked in a single solution. All the test pieces are required to pass the sealing test, and the material is not eroded, deformed or perforated after soaking.
Temperature cycling test
The product is installed at one end of a 150mm*600mm pipe, and the test piece is placed in an environment box with a bracket to ensure the free flow of air on its surface. Twenty temperature cycles were performed, each lasting 12 hours. The temperature changes are shown in Table 1 “Temperature Cycle Change Table”. During the test, the inside of the catheter was pressurized to 50 kPa. After the test results, all samples are required to pass the sealing test.
Table 1 Temperature cycling table
Test period (h) Temperature change (°C)
00:00-15
00:00 to 00:45-15 rose to 30
00:45 to 6:0030
6:00 to 6:4530 rose to -15
6:45 to 12:00-15
Heat test
Place the product in an air circulating oven and maintain the temperature at 60±2°C for 720 hours or 70±2°C for 120 hours. After the test results, the product was installed in the catheter and all samples were required to pass the sealing test.
Puncture resistance test
The inflatable bag was folded in half and pierced at a speed of 200 mm/min with a screwdriver (working part type A-1-5.5) at the overlapping part. Puncture force needs ≥100N.
Pressure test
Install the product into the appropriate piping and inflate to 300KPa. Within 15 minutes, increase to 450KPa, then every 15 minutes, increase 50KPa. The final rupture pressure should exceed 900 KPa.
The company sincerely provides the following technical solutions to the relevant questions - pipe sealing airbags, cable ducts, cable pipe seals, cable pipe plugging, cable pipe waterproofing, pipe plugging, cable pipe sealing waterproof.

Round separator,also known as Vibrating Sifter,vibrating filter,Vibrating Sieve,vibro sifter,rotary sifter, uses vibration motor as the source of vibration,equipped eccentric hammer on the both sides of motor,the rotation of hammers change circumrotate to level ,upright and incline movement,then pass these three movement to surface of the screen mesh. Adjust the phasic angle of the top hammer and bottom hammer to change the movement track of the material. This will help to screen different materiel in different situation successfully.
 
Type of screen frame:flange type,ring type,gasket type,glue type.
 
Feature
The machine screening accuracy exceeds 90%.
It adopts whole sealing structure design,the sealed effect is fairly well,no dust pollution,no leaking liquid,  no material left in machine,and no dead angle in the net frame.
Small volume and light weight,easy to be installed and maintained.
The outlet can be adjusted at any angle,and it is easy to change the screen.
The rubber ball device can reduce the chance of jam on the screen.
By adding the Ultrasonic Instrument Conversion device, superfine materials up to 600 mesh can be  sieved.
