GR202 High Temperature High Pressure dyeing machine
1.dyeing, boiling off, bleaching and water washing, etc
2.Automatic computer controlled system
3.Low maintainance efficiency
It is mainly designed for the application of dyeing, boiling off, bleaching, and water washing, etc. working procedure for hank yarn, bobbin or scattered fibre on the cotton, wool, or chemical fibre processing machine.
Machine type: Vertical cylinder type
Capacity: vary from 1kg to 1000kg
Working temperature: 130oC
Max working pressure: 0.4Mpa
Both ratio: 1:7-9
Automatic computer controlled system
Low maintainance efficiency
Heat exchanging method: Adopt coil type heat exchanger, which can be used for heating, and also can be used for cooling.
Heat exchanging speed: When the heating steam pressure is 0. 4Mpa. 40minutes will be required for the liquid inside the dyeing beck raising from 20oC to 130oC. When the cooling water pressure is 0. 3Mpa and the water temperature is 20, 40 minutes will be required for the liquid inside thedyeing beck lowering from 130oC to 80oC.
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 cenrifugal pump.
Sealing method of boiler body: Adopt self-sealing type rubber adhesive tape. The working pressure inside the boiler will make the rubber adhesive tapeclosely attaching to the flange connoid surface of the boiler mouth so as to reaize the sealing or air-jacking target.
Opening method of boiler cover: Firstly open the safety insurance air valve to release the pressure inside the boiler. When there is no air exhausted 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, the cover will be closed.
