Description
Overview
Designed for dyeing, boiling off, bleaching, and water washing, etc.
Suitable for hank yarn, bobbin or raw stock fiber
Machine type: vertical cylinder
Vat diameter: Ф600mm
Cone quantity: 7 x 7 = 49 cones
Working temperature: 130°C
Max working pressure: 0.4 MPa
Both ratio: 1:7 to 9
With computerized control system
Heat Exchanging
Coil type heat exchanger, which can be used for either heating or cooling
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
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
Operation Details
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
Sealing of boiler: rubber adhesive
The working pressure inside the tank will make the rubber seal closely to attach the flange
The conical surface of the tank mouth is to enhance the sealing
Opening of tank cover: first open the air valve to release the pressure inside the boiler; wait until no exhausted air going through 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; the cover will be closed
