Abstract
The invention discloses a kind of methods that transmission metering control system reduces size deviation, the following steps are included: the first step, the transmission metering pump big to size deviation is replaced, replaced metering pump is after decomposing, it weighs, the gear in same weight range is sorted out, the gear in same weight range is mounted on the same metering pump to transmission gear, keep every a pair of of transmission gear melt-stoichiometry identical, the same every hole melt discharge-amount of metering pump is consistent.The method that the transmission metering control system reduces size deviation realizes accurate measurement management, reduces size deviation, reduces spinning cake drop etc..
Description
Technical field:
The present invention relates to field of polyester fiber, are especially a kind of side of transmission metering control system reduction size deviation
Method.
Background technique:
Existing transmission metering pump is because gear is worn in various degree, and size deviation is larger between spindle position；Furthermore transmission metering control
System processed is 6 spindle positions, one Frequency Converter Control, and single position is laid particular stress on or can not be gently adjusted partially, meeting so in process of production
Single ingot spinning cake weighting or partially light is caused, thus the problem for causing size deviation larger.
Summary of the invention:
The technical problem to be solved by the invention is to provide a kind of accurate measurement management, reduce size deviation, reduce spinning cake
The method that the transmission metering control system of drop etc. reduces size deviation.
The technical solution of the invention is as follows, provides a kind of method that transmission metering control system reduces size deviation, packet
Include following steps:
The first step, the transmission metering pump big to size deviation are replaced, and replaced metering pump is after decomposing, to biography
Moving gear weighing, sorts out the gear in same weight range, the gear in same weight range is mounted on the same meter
On amount pump, keep every a pair of of transmission gear melt-stoichiometry identical, the same every hole melt discharge-amount of metering pump is consistent；
Second step makes each spindle position form independence by independent Frequency Converter Control by establishing driven separately control system
Transmission measurement control unit the frequency converter of control metering pump is individually adjusted by independent transmission measurement control unit
It is whole, with deviation of weight between balanced spindle position and spindle position.
Further, the gear section in same weight range is respectively 141.573-141.563g and 141.562-
141.552g。
The invention has the advantages that each by the way that the metering pump of the original joint each spindle position of Frequency Converter Control to be improved to
Metering pump by independent Frequency Converter Control, meanwhile, under original spinning condition, by different metering pump internal gears gap
Adjustment, it is unified by external metering pump conversion system, carry out independent management of classifying, establish driven separately control system, accurately
Management through quantification reduces size deviation, spinning cake drop etc. is reduced, to meet customer requirement.
Specific embodiment:
The invention will be further described With reference to embodiment:
A method of transmission metering control system reduces size deviation, comprising the following steps:
The first step, the transmission metering pump big to size deviation are replaced, and replaced metering pump is after decomposing, to biography
Moving gear weighing, sorts out the gear in same weight range, the gear in same weight range is mounted on the same meter
On amount pump, keep every a pair of of transmission gear melt-stoichiometry identical, the same every hole melt discharge-amount of metering pump is consistent；Specifically, weight
The transmission gear that amount is 141.573-141.563g is classified as same weight range, and weight is being classified as separately for 141.562-141.552g
One weight range；
Second step makes each spindle position form independence by independent Frequency Converter Control by establishing driven separately control system
Transmission measurement control unit, by independent transmission measurement control unit, to each frequency converter of control metering pump individually into
Row adjustment, with deviation of weight between balanced spindle position and spindle position, so as to improve the big problem of size deviation.
It is below the data comparison of improvement front and back identical product specification:
Product specification (dtex/F): 260/48POY
Before implementation:
1, line density deviation ratio (%): ± 1.2
2, line density coefficient of variation CV value (%): 0.70
After implementation:
1, line density deviation ratio (%): ± 0.8
2, line density coefficient of variation CV value (%): 0.50
Only the preferred embodiment of the present invention has been described above, but is not to be construed as limiting the scope of the invention.
