With use of novel combined centrifugal pump and built-in heat exchanger the machine can be appiied for dyeing, scouring,etc.

Use:It's used for dyeing and bleaching all kinds of bobbin yarn with the

material of cotton, polyester, nylon, wool, hemp and blended yarns.

Main Purpose:

With use of novel combined centrifugal pump and built-in heat exchanger the machine can be appiied for dyeing, scouring, bleaching,washing skein,cheese or loose material of cotton,wool,chemical fibers,etc.

Technical characteristics:

Machine type:Vertical cylinder typeWorking capacity(Refer to the specification list)

Working temperature:130°CMaximum working pressure:0.3MPaBath ratio:1:5Heat 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 0.4 MPa,40minutes will be required for the liquid inside the dyeing beck raising from 20°C to 130°C.When the cooling water pressure is 0.3MPa and the water temperature is 20°C,40 minutes will be required for the liquid inside the dyeing beck lowering from 130°C to 80°C.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.Sealing method of boiler body:Adopt self-sealing type rubber adhesive tape.The working pressure inside the boiler will make the rubber adhesive tape closely attaching to the flange connoid surface of the boiler mouth so as to realize 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.Overall size:(Refer to the specification list) unit:mm
