Description
Technical field
The utility model belongs to the manufacture of chemical industry wound tube heat exchanger, particularly relates to a kind of for for carrying out the axial automatic spacing of friction-driven of coiling heat exchanger tube around pipe machine around heat exchange of heat pipe internals around body.
Background technology
Along with the development of national economy, chemical industry scale is increasing, and the wound tube heat exchanger as one of heat transmission equipment kind uses further extensive.
Be made up of internals and housing around heat exchange of heat pipe.In internals, hundreds of, thousands of heat exchanger tubes with around body central pipe for the centre of gyration carries out helical arrangement, heat exchanger tube two ends are each passed through the via hole of two ends tube sheet correspondence arrangement, the heat exchanger tube mouth of pipe respectively with aperture, tube sheet outer end welded seal.Heat exchanger tube is layering coiling centered by central tube, and the rotation direction of adjacent two layers is contrary.
Divide sub-thread stream and multiple flow two kinds of versions around heat exchange of heat pipe, multiple flow internals diameter can reach more than 4m, and length can reach 18m, and weight can reach more than 180 tons, and heat exchanger tube quantity reaches 5000, and the coiling number of plies can reach more than 30 layers.Fig. 1 be a kind of 8 plumes around heat exchange of heat pipe internals sketch, Fig. 2 is its tube sheet end view.

Tradition axle type of drive centered by pipe machine, when heat exchange of heat pipe diameter, weight are increasing, size, the weight of the parts that are in transmission connection are also increasing.Make around pipe machine drive disk assembly and the connection around body tube sheet also further difficult.
Therefore, in conjunction with around pipe processing characteristic, finding a kind of new kind of drive to drive and rotating around body, carry out heat exchanger tube coiling is significantly.
Utilize backing roll and the frictional force between body tube sheet cylindrical, motor reducer Direct driver backing roll, drive and rotate around body, realize, around heat exchange of heat pipe internals heat exchanger tube coiling processing, central shaft thoroughly to be avoided to drive and rotating around body the series of problems brought.
But the factor impacts such as the processing of supported roller diameter error, each backing roll alignment error, tube sheet and rigging error, when gyration done by workpiece, self will inevitably produce an axial float.Owing to needing around body to do gyration for a long time, therefore, will move to one end gradually, finally depart from backing roll, make cannot carry out around pipe processing, even cause equipment, security incident.
