Internal twisted tape testing system

Abstract

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.

Description

technical field [0001] The invention relates to a test platform, in particular to a spiral bond test system. Background technique [0002] Spiral ties, also known as twisted iron, spoilers, spiral flat steel, etc., are installed in heat exchanger tubes and are mainly used to improve heat exchange efficiency. When the fluid enters the heat exchange tube, the spiral bond makes the fluid flow in the tube in a spiral state along the spiral bond (that is, the fluid enters a turbulent state), which increases the contact area between the fluid and the heat exchange tube wall, and the spiral bond itself Driven by the flow energy of cooling water at a certain flow rate, automatic rotation and vibration will also occur. The side edge of the spiral bond can strongly disturb the boundary stagnant layer close to the tube wall. In convective heat transfer, the boundary layer with the largest thermal resistance The heat is effectively enhanced, thus greatly improving the heat transfer coe...

Problems solved by technology

[0003] When producing a spiral bond, the performance parameters of the spiral bond are usually designed according to its specific application environment, such as corrosion resistance, wear resistance, chemical stability, high temperature resistance, smoothness, water resistance, stiffness, toughness, etc. Performance, in the prior art, the performance test of the spiral bond has not yet formed a mature test platform, and most of them are still in the theoretical stage, so it is impossible to form a real test conclusion and effectively verify the operation of the spiral bond in the real use environment Reliability of spiral ties under various conditions of use
