The invention discloses an internal twisted tape testing
system. The
system comprises four testing platforms, wherein each testing platform comprises a water tank, a flow dividing tank, a water inlet
pipe, a water outlet
pipe, a
circulating pump, a flow meter, a pressure valve, a bracket, a testing
pipe, pressure gauges, an observation pipe, a return tank and a return
branch pipe; the circulating pumps, the flow meters and the pressure valves are mounted on the water inlet pipes; an internal twisted tape is mounted in each testing pipe; the
water tanks are used for accommodating a medium for simulating environment; the observation pipes are mounted on the testing pipes; the pressure gauges are mounted at the two ends of the testing pipes and on the flow dividing tanks; the medium sequentially passes through the
water tanks, the water inlet pipes, the flow dividing tanks, the testing pipes, the return tanks, the return
branch pipes, the flow dividing tanks, the water outlet pipes and the
water tanks under the action of the circulating pumps, so as to form circulating flow in the testing platforms and further simulate the real service environment of the internal twisted tapes. According to the internal twisted tape testing
system, after testing, the performance indexes of products are tested and the reliability of the system in a practical environment is verified, so that a real and reliable data support is provided for product production.
