Then circulating pump B1 being performed identical control to run, it is after the circulating pump A1 knot speed operation time that circulating pump B1 starts the time, i.e. circulating pump A1 starts freely to slow down when stopping rather than after circulating pump A1 slows down stopping.During this, circulating pump A1 and circulating pump C1 does not runs.The cheese (or warp beam) of dye vat subregion S2, under the pressure of circulating pump B1, through liquid back pipe 220, circulating pump B1, from cheese (or warp beam) inside of dye vat subregion S2 to exosmosis, is dyeed by dye liquor.The dye liquor returned of infiltration is hoarded in dye vat.
The most again circulating pump C1 being performed identical control to run, during this, circulating pump A1 and circulating pump B1 does not works.Dye liquor is under the pressure of circulating pump C1, and through liquid back pipe 220, circulating pump C1, internal to exosmosis from the cheese (or warp beam) of dye vat subregion S3, cheese or warp beam to dye vat subregion S3 dye.The dye liquor returned of infiltration is hoarded in dye vat.
Last control circulating pump A1 in an identical manner, such loop control, shown in the operation curve of each little pump controlling curve as shown in Figure 4, it is achieved dyeing cycle.
Comparative example
A kind of subregion dyeing installation, including: dye vat and blood circulation.
Described dye vat is essentially identical with the dye vat in embodiment 2.
In described blood circulation, being divided into the dye axle of three groups to share a main pump, the dye liquor being switched not same district group by valve is circulated, and the method realizing subregion dyeing.
But, in this comparative example, use the mode of valve transfer, need valve to switch once in every about 15 seconds, because switching frequency is high, cause valve spoilage high, when valve is quickly opened simultaneously, dye liquor impulse force is easy to more greatly wash out cone yarn, causes yarn strength relatively low, the most easily produces the quality problems such as dyeing flower.
