Abstract
The invention discloses an energy-saving round hole auxiliary nozzle for an air jet loom and a preparation method for the same. An installation angle of the nozzle is zero degree formed by Beta1+Beta2; an injection angle (a) is 6 degree; the diameter of an injection hole of the auxiliary nozzle is 1.0mm; the internal opening diameter and the external opening diameter of the injection hole are both 1.mm; an included angle between a connection axis of the center points of the two openings and the inner wall surface is 50 degrees, so the length of the injection hole is properly increased and spraying jet diffusion and speed attenuation can be reduced; auxiliary nozzle space distance is increased when a wefting insertion is met; auxiliary nozzle energy consumption is reduced; and the production cost is lowered. The figure 1 is the nozzle, 2 is the injection pipe, 3 is the pipe seat, 4 is an adjusting screw and 5 is the pipe sleeve.
Description
Technical field
The present invention relates to the energy-saving pilot jet of used in jet loom, and relate to the installation method after the improvement of energy-saving pilot jet.
Technical background
In air-jet loom, pilot jet is responsible for by weft yarn refile to the critical component of shed open, and the quality of its processing performance is directly connected to the key issues such as the production efficiency of air-jet loom, product quality and energy consumption.Therefore, be described as " heart " of air-jet loom.Along with the development of production technology, the fabric width of Novel air jet loom breaks through 540cm, therefore generally arranges 25 ~ 65 pilot jets along fabric width direction and carry out relay jet air-jet weft insertion.So in the process of normal wefting insertion, the gas consumption amount of pilot jet accounts for about 75% of the total gas consumption amount of whole air-jet loom.Therefore, in order to boost productivity, reduce energy ezpenditure, require from the jet of pilot jet ejection better parallel with weft yarn flight path, and convergence is better, Diffusion of gas stream speed is slower.
In the last few years, the pilot jet commercially sold mainly contained circular hole and not rounded pass, and wherein circular hole pilot jet is divided into single hole again, diplopore and porous, pass through the comparison of experiment and mill practices, find that single round hole is compared with the pilot jet of other passes, has good air-flow convergence.The present invention aims to provide and a kind ofly can reduce supply gas pressure and reduce the energy ezpenditure of air-jet loom, improves the directionality of air-spray and reduces the pilot jet of pilot jet to the air-jet loom of warp yarn friction.
Summary of the invention
The object of the present invention is to provide the energy-saving pilot jet of a kind of used in jet loom, this energy-saving single round hole pilot jet reduces injection diameter, and inner chamber is optimized for the trapezoidal spray orifice length that makes to be increased, and orifice center alignment reed groove offset inboard changes the direction of air-flow.The result reached is that pilot jet is parallel with warp thread, reduces the friction to warp thread, improves weave quality, and reduce supply gas pressure under the condition ensureing normal wefting insertion, reduces the diffusion of air-flow, reduces production cost.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
An energy-saving pilot jet, the inner chamber of described pilot jet comprises a trapezoidal portion and two halves rounded portions.Outer wall is the flat portion consistent with common pilot jet.
Energy-saving pilot jet of the present invention is applied on air-jet loom: in high speed weaving process, and the pilot jet first half constantly passes in and out between dense warp thread, because warp thread gap is less, so there is more serious rubbing action between pilot jet and warp thread.If pilot jet setting angle has about 6 degree, the rubbing action between pilot jet and warp thread can be strengthened, affect fabrics cloth cover quality.Pilot jet is parallel to warp thread and installs by this invention, and warp thread stream is tended to be steady, and by nozzle bore outward opening deflection reed side, inside the deflection reed making jet, to be conducive in wefting insertion process air-flow to the effect of weft yarn.
Compared with prior art, pilot jet injection diameter of the present invention is used to reduce, when supply gas pressure is constant, the effluxvelocity of ejection increases on the contrary, and simultaneously because spray orifice is perpendicular to the trapezoidal inclined-plane of inner chamber, pilot jet wall thickness increases, jet convergence in reed is improved, velocity attenuation is slack-off, so the spacing that suitably can reduce pilot jet supply gas pressure or suitably increase between pilot jet, reduces the gas consumption in weaving process.
The present invention aims to provide one and can reduce supply gas pressure or improve pilot jet spacing and reduce warp yarn friction, improves the energy-saving pilot jet of fabric quality.
The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
