Description
[technical field]
The utility model relates to a kind of samplings of helical angle of inner-grooved copper tube to cut open pipe device, belong to helical angle of inner-grooved copper tube survey
Preparation (cuing open pipe, scribing line) field of sample when amount.
[background technique]
Inner screw thread copper pipe is widely used in the condenser and evaporator of air-conditioning refrigeration system.As two device heat transfer intensifications need
It asks, forming internal threads technology constantly improve and improving, and large helix angle inner screw thread copper pipe becomes Main Trends of The Development.
Inner screw thread copper pipe is also known as non-flat slip pipe, refers to that smooth outer surface, inner surface have certain amount, certain rule screw thread
Copper pipe.Therefore heat exchange area is increased compared with same specification light pipe, the pyroconductivity of refrigerant side is improved, so that gas-liquid circle
The disturbance in face greatly increases, and the bottom of inner screw thread copper pipe and the refrigerant liquid at top are effectively stirred, simultaneously because surface
Tension makes the reasons such as thinning of liquid film, so that its heat transfer coefficient increases.
The presence of helical angle of inner-grooved copper tube is to generate fluid in pipeline and radially different two to make fluid rotary
Secondary stream, increases the intensity of turbulent flow, so that heat convection be made to be strengthened, the coefficient of heat transfer increases therewith, so helical angle increases energy
Enhance the coefficient of heat transfer, but with the increase of helical angle, the pressure loss is consequently increased, therefore helical angle is also not and is the bigger the better, and
It is to need accurate control.The helical angle control margin of tolerance of inner screw thread copper pipe is ± 2 ° at present.
Standard GB/T/T 20928 " seamless riffled tube " is for the regulation of spiral angular measurement: tubing longitudinally splitted,
Flattening, finds out longitudinal reference line, reads helical angle with protractor.At present there are mainly two types of sampling modes, one is manual scribing line,
Scissors splits pipe fitting, and this method is although easy to operate, but operating error is big, and another kind is wire cutting pipe fitting, this method operation
Required precision is high, step is complicated, higher cost.
