Description:Model: DF241A-10 DF241A-25 DF241A-50 DF241A-100 DF241A-200 DF241A-350 DF241A-700 Principle of operation: to put the materials into the dyeing trough, through the heated dye stuff, the materials will be flowed from the inner layer to the outer layer continuously with the cycling pump, or changing the recycling flowing direction via the alternation of the equipments, so that the even dyeing can be achieved under the regulated temperature and time. When the temperature of the dye liquid is above 980C, it needs to fill the compressed air in the dye trough for pressing (It can be pressed by the auxiliary pump when the dye trough is filled with dye stuff), so as to raise the boiling point of the dye liquid and ensure its normal operation. This equipment is characterized by compact structure, small bath ratio, and high automation. In addition, it adopts two-way stainless steel mixed-flow pump with high efficiency and high oil and gas corrosion resistance, so that it can accomplish the most ideal dyeing quality and economic benefits. Specifications and features: 1) Machine type: square cylinder 2) Operation capacity: see the table below 3) Operating temperature: 1400oC 4) Operating pressure: ≤0.4MPa (gauge) 5) Operating medium: dye liquid and vapor 6) Bath ratio: small bath ratio: 1:4; medium bath ratio: 1:8 or fully filled 7) Method of heat exchanging: the coil pipes are allocated on the bottom of dye trough, which can be heated or cooled indirectly with vapor or cooled water respectively 8) Vapor pressure: 0.5MPa (gauge) 9) Pressure of cooled water: 0.1 - 0.5MPa (gauge) 10) Press mode: the medium and small bath ratio shall be pressed with filled air, and it shall be pressed with auxiliary pump when it is fully filled 11) Recycling method of dyeing liquid: the positive and negative recycling of dyeing liquid will be adjusted by the cylinder through the switching device inside the centrifugal pump 12) Driving mode: the motor drives the corrosion resistant pump directly 13) Sealing methods of the trough mouth: pressure seat 14) Opening method of trough cover: opened and closed by the cylinder quickly, equipped with pressure releasing safety lock and power automatic switch apparatus 15) Equipment main materials: 1Cr18Ni9Ti 16) Automatic control device: temperature remote control, automatic control of dye liquid direction exchange, and automatic control of bath ratio level 17) Serving capacity (kg): 10, 25, 50, 100, 200, 350, 550
