Problems solved by technology
[0002] The existing metering pumps used to transport the spinning liquid in the production process of viscose filament rollers in the chemical fiber industry are two single-stage pumps, and the two single-stage pumps need to transport the spinning liquid to the spinneret through the pump bridge respectively. Connection increases the possibility of spinning solution leakage, inconvenient operation and maintenance, difficult for several test pumps, and greatly increased cost
[0003] Moreover, most of the currently existing delivery devices, metering delivery pipes and volumetric tube metering delivery pump devices operate in a single set, which fails to achieve smooth and continuous metering output, and cannot perform quantitative output and metering of all media flowing through the volumetric tube device.
Such a conveying device cannot be well applied to the production of viscose filament roller twin filaments
