The main features of the yarn raking machine are: the winding speed is fast, up to 550 rev / sec; the groove guide yarn and the skein of the skein have no unevenness at the left and right ends, thereby avoiding the dyeing due to the uneven thickness of the skein being shaken. The yarn frame; its special frame expansion mechanism makes the frame shrink automatically, which greatly reduces the labor intensity; it can shake the large skein of 335~500 grams, reducing the number of finished yarn connectors; using imported Japanese Fuji, Taiwan Taian, Tiande and other control components, PLC, etc., to ensure stable and reliable operation of the machine; the yarn breakage sensor produced by Japanese technology, in the case of yarn breakage, the machine can start the brake device, to ensure that in 3~5 The circle stops; the machine has a clear indicating device, so that the operator can see the status of the machine at a glance; the whole machine runs smoothly.
High flux tube is a kind of high efficiency heat exchanger tube which sinters a layer of porous surface with special structure on the inner surface of ordinary heat exchanger tube by powder metallurgy method.
• The holes in the surface porous layer are connected with the holes, which can significantly enhance boiling heat transfer. With grooves on the outer surface, the heat transfer effect can be increased by more than 10 times.
• High Flux Tube is tube element with the highest heat transfer coefficient up to now.
High flux tube can be classified into three groups: Sintered high flux tube, Sprayed high flux tube and Machined high flux tube. Among them, sintered high flux tube is the most expensive for its complex processing method and high efficiency; machined high flux tube is applied to mediums with high surface tension, its performance is in between; sprayed high flux tube is the cheapest for its easy process and low efficiency.
Compared with the bare tube, the sintered surface porous tube has the following advantages:
(1) it can significantly enhance the boiling heat, reduce the heat transfer area of about half, and have broad application prospects in the chemical and petrochemical plants such as large ethylene and large aromatics.
(2) in a very small difference in the maintenance of boiling, low taste energy recovery and low temperature boiling heat transfer has a great value, can be used to reduce the temperature of the heating steam.
(3) the critical heat load is more than 50% higher than that of the ordinary pipe.
(4) has good scale inhibition performance.
