Negative pressure control method for compact spinning negative pressure system

Abstract

The invention relates to a negative pressure control method of a compact yarn negative pressure system, the compact yarn negative pressure system comprises a negative pressure centrifugal blower, a blower motor, a filtering device and an air duct, the flow direction of the negative pressure airflow is: the negative pressure airflow passes through a compact yarn device and enters the air duct, the filtering device and the blower, and then being discharged, which is characterized in that: mounting a pressure pickup and alarming device on the end of the air duct far away from the blower, the pressure pickup takes a two-way communication with the transducer of the blower motor, the pressure pickup and alarming device take a one-way communication, setting a pressure range for the pressure pickup, the range is the needed negative pressure range of the compact yarn device, the pressure pickup takes the one-way communication with the relay of the compact yarn mainframe. Through the application of the invention, the negative pressure stability of the compact yarn device is better ensured during the whole spinning course, so the negative pressure stability in the whole spinning course is ensured, ensuring the quality of the final yarn. At the same a good protection to the blower motor is played.

Description

technical field [0001] The invention relates to a negative pressure control method for a compact spinning negative pressure system. It belongs to the technical field of compact spinning negative pressure control system. Background technique [0002] The traditional ring spinning technology has been developed for decades in our country, but due to some structural problems, it is determined that there is a spinning gap between the nip of the front roller and the twisting point in the drawn fiber strands. Yarn triangular area, in which the fiber bundle after being drafted is in the shape of a flat strip, and the edge fibers are not constrained in any way, and one or all of the edge fibers are separated from the main fiber bundle to form hairiness and flying flowers, and the hairiness will affect the subsequent process. Larger negative impact, flying flowers pollute the working environment of workshop workers. Most of the edge fibers are not completely straightened when advanc...

Problems solved by technology

Due to the special working environment of textile mills, when the amount of short-lint deposited on the filter device exceeds a certain amount, the pressure required by the compact spinning device is insufficient, which affects the yarn quality. When the short-lint deposits are serious and are not cleaned up in time, the fan motor will be overloaded and the motor will be burned.
