Power conservation control method of cheese dyeing machine

Abstract

The invention provides a power conservation control method of a cheese dyeing machine, which comprises the following steps: according to the dyeing technology for different yarn varieties of the cheese, transmitting the set data to a transducer for controlling the frequency of a water pump motor by a power conservation controller, and transmitting the set data to a computer of a dyeing machine computer and a programmable controller of the dyeing machine for controlling the direction and run time of a dye liquor commutator. The power conservation effects are as follows: 1, the power saving rate is in the range of 20%-50% and the cost can be recovered within the shortest time under the condition of continuous operating mode; 2, the phenomena of motor heating and abrasion of moving parts arereduced, thereby effectively prolonging the service life of the motor, the transducer and the commutator, and lowering the maintenance cost; 3, the power factor is improved, the reactive power loss is reduced, the soft starting characteristic is provided, and large current impact does not exist at the time of starting; 4, the dyeing quality is improved, and the color difference and the layer difference are avoided effectively; and 5, the influence on yarn strength caused by flowing water impact is prevent.

Description

technical field [0001] The invention relates to a power-saving control method for a cheese dyeing machine, which belongs to the textile field. Background technique [0002] At present, in the package yarn dyeing process, the flow and direction of the dye solution are kept constant, which may easily cause the flow rate of the dye solution at different positions of the package to be different, and more seriously, it will cause the shoulder color line and internal and external differences. In order to dye evenly, when designing the shape of the circulation main pump, due to the design requirements, the water pump is equipped according to the resistance of the maximum flow and a certain design margin, and the power matching requirement is about 20% larger, which we call the design margin loss. . But this will increase the power consumption of the main pump, and if the pump speed is too fast, the adsorption of the dye solution on the yarn cannot be guaranteed to be 100% stable. ...

Problems solved by technology

But this will increase the power consumption of the main pump, and if the pump speed is too fast, the adsorption of the dye solution on the yarn cannot be guaranteed to be 100% stable. At the same time, the density of the package yarn when it first enters the dyeing vat is lower than that after a certain period of time. , If the dyeing liquid flow rate is too large, the yarn will be worn, the yarn hairiness will increase, and the strength will decrease.
