The main purpose of the steaming machine is to combine the continuous silk thread with weaving conditions and stop the setting after twisting, that is to stabilize the twist under a certain pressure and temperature, and obtain balanced and non twisting silk thread. The operation process of yarn steaming machine is vacuum preheating humidification heat preservation constant temperature vacuum cooling ending. The dry screw vacuum pump for vacuum pumping is generally water ring type dry screw vacuum pump. The working pressure of the steaming machine is – 0.085-0.1mpa. The water ring type dry screw vacuum pump can extract a certain amount of condensable gas.
The yarn steaming machine with dry screw vacuum pump can stop the uniform, accurate and mild steam treatment of yarn or fabric from low temperature to high temperature. The steam process is controlled by microcomputer, and the temperature is controlled to ± 0.5 ℃. It can ensure that the yarn steaming process can be reproduced accurately according to the budget process, avoid the generation of condensate water to the maximum extent, and make the yarn get uniform and mild steam treatment.
Therefore, it can be used in this process. How large the water ring type dry screw vacuum pump is used, the suitable dry screw vacuum pump can be selected according to the size of the yarn steaming machine and its own time request.
