NovaStar, DG157, New, High-Temperature High-Pressure Yarn Dyeing Machine, 30kg to 50kg Capacity, 130°C (New)

NovaStar, DG157, New, High-Temperature High-Pressure Yarn Dyeing Machine, 30kg to 50kg Capacity, 130°C

Description

  1. Overview
    1. This series of machines is mainly designed for the application of dyeing, boiling off, bleaching, and water washing, etc.
    2. They are working for hank yarn, bobbin or scattered polyester yarn.
    3. Machine type: vertical cylinder type.
    4. Working temperature: 130 °C.
    5. Max. working pressure: 0.4 MPa.
    6. Bath ratio: 1:7 to 9.
  2. Model DG157 Specifications
    1. Vat diameter: Ø500 mm.
    2. Motor power: 7.5 kW.
    3. Quantity of cone: 5 × 7 = 35 pieces.
    4. Capacity: 30 kg.
    5. Working temperature: 130 °C.
  3. Model 60 Specifications
    1. Vat diameter: Ø600 mm.
    2. Motor power: 11 kW.
    3. Quantity of cone: 7 × 8 = 56 pieces.
    4. Capacity: DG157 kg.
    5. Working temperature: 130 °C.
  4. Control and Heat Exchange
    1. With computerized control system.
    2. Heat exchanging: coil type heat exchanger, which can be used for either heating or cooling.
    3. Heat exchanging speed: when the heated steam pressure is 0.4 MPa, 40 minutes will be required for the liquid inside the dyeing barrel raising from 20 °C to 130 °C.
    4. When the cooling water pressure is 0.3 MPa and the water temperature is 20 °C, 40 minutes will be required for the liquid inside the dyeing beck to lower from 130 °C to 80 °C.
    5. Recycling 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.
  5. Sealing and Cover Operation
    1. Sealing of boiler: rubber adhesive.
    2. The working pressure inside the tank will make the rubber seal closely attach the flange.
    3. The conical surface of the tank mouth is to enhance the sealing.
    4. Opening of tank cover: first open the air valve to release the pressure inside the boiler.
    5. Wait until no exhausted air going from the exhaust valve and the reading of pressure gauge is zero, withdraw the wrench handle, open the clamping hoop to remove the flange; and then open the cover with drag weight.
    6. The cover will be closed.
  6. Configuration
    1. Electrical cabinet: made of stainless steel.
    2. Electrical components: Siemens or Omron brand.
    3. Electromagnetic valve: Taiwan Airtac.
    4. Pump: centrifugal pump.
    5. Motor: Wannan brand.
    6. Inverter: Senlan brand.
    7. Temperature control: computer control of heating, cooling, warming, etc.
    8. Heat exchanger: internal coil heating.
    9. Valve: pneumatic angle valves for heating, cooling, pneumatic butterfly valves for water inlet and water outlet.
    10. Cover opening: pneumatic operation.
    11. Surface finishing: polished inside the dye vat, sand blast outside the dye vat.
    12. It has one set of carrier basket.
    13. Machine body material: stainless steel 321.
    14. Accessories: (1) set of seal ring for dye vat, (1) set of seal for main pump, and (1) set of seal for reversing shaft.
  7. Safety System
    1. Triple safe interlocking mechanism for cover and safety valves for the main tank.
