Function and control of Fujian dyeing Machine According to the requirements of controlled dyeing process, provides stable and high-quality dyeing results for both routine and special dyeing, and can run one or more dyeing schemes simultaneously. The following automatic dyeing machine factory for you to introduce the main points of function.

Control of flow rate and pressure: Flow rate and pressure are two important parameters of overflow dyeing machine, which are determined by main circulating pump. The flow rate is necessary to ensure the exchange between dyes and fabrics, and it must be large enough to make as little change as possible in a particular dyeing process. The automatic dyeing machine is completely controlled by the main pump. Pressure in the case of a fully automatic dyeing machine is the pressure generated by the nozzle.

In dyeing process, flow and pressure play a very important role, different fabrics and processes on the flow and pressure of dye (jet force or pressure difference) is different. For example, when comparing high-count fabrics with larger surfaces with faster-dyeing processes, flow rates need to be higher; For light fabrics and fabrics with delicate surface, low jet force is required. For fabrics of large gram weight, sufficient flow rate and strong jet force are required. Therefore, the flow rate and pressure should vary according to different fabrics and processes.

The selection of fujian dyeing machine is also related to whether the yarn is used for knitting or woven. The flow rate selected for dyeing knitting is greater than that for weaving. If the flow rate is improperly selected, it will not only affect the dyeing quality, but also cause a certain amount of energy waste. Therefore, it is necessary to control the flow rate to ensure that a reasonable flow rate can be given under any conditions (namely, the change of yarn type and the change of loading amount), so as to achieve the so-called synchronous dyeing.

In order to meet the change of flow and pressure, the automatic dyeing machine is controlled by the closure adjustment of the main pump outlet. Due to the influence of human factors, this control method is not accurate enough. At the same time, the main circulation pump is not working at the working point, the efficiency is reduced. According to the characteristic curve of the main pump, in a certain speed adjustment range, the main pump speed can be changed through AC frequency conversion to realize the change of flow rate and head, so as to meet the requirements of different dyeing process, so as to ensure that the automatic dyeing machine always works at the working point of corresponding flow rate and curve, so as to save energy.
