Abstract
The invention discloses a weft insertion diversion trench airflow simulation measuring system, which comprises a flow guide pipe chase, wherein two or three auxiliary spray nozzles are arranged in the horizontal direction of the flow guide pipe chase; the auxiliary spray nozzles are all connected onto an auxiliary airflow jetting control system; a pneumatic sensor is arranged inside an inner cavity of the flow guide pipe chase; the pneumatic sensor is connected with a transducer; and the transducer connected with a storage oscilloscope. The auxiliary spray nozzles and the pneumatic sensor are adopted to relatively move in the weft insertion flow guide pipe chase, so as to detect the velocity variation of airflow in the pipe chase and determine the most appropriate size of the flow guide pipe chase. The length of the spraying interval of each auxiliary spray nozzle is changed, and the intervals between the pneumatic sensor and the auxiliary spray nozzles are changed, so that the relations between factors and the weft insertion trench airflow distribution can be measured; and the relations between the most appropriate size of the flow guide pipe chase and the spraying of the auxiliary spray nozzles can be researched, so as to form a weft insertion airflow field that can save the most flow rate.
Description
Technical field
The invention belongs to the air-jet loom field, the concrete pneumatic picking system that relates to relates to a kind of simulation wefting insertion guiding gutter gas flow measurement system in particular.
Background technology
As the wefting insertion medium, weft yarn flies along the wefting insertion groove pneumatic picking in the wefting insertion process with high velocity air.The size of the wefting insertion groove that uses now is determined at the beginning of the eighties, and the speed of its air-jet loom has only 450 rev/mins, and filling speed has only the 50-60 meter per second.And present 900 rev/mins of the speed of air-jet loom, filling speed 100-150 meter per second, flying distance 2-4 rice, the speed of loom and weft yarn flying speed double.
Leap in the shed open process at weft yarn, the characteristic of weft yarn flight depends primarily on wefting insertion such as auxilliary nozzle and special-shaped reed parts in addition.The wefting insertion jet-stream wind is dispersed very fast, just significantly decay after the main injection air-flow continues tens millimeters, and the continuity of weft tracting flow relies on guiding and the protection of wefting insertion water conservancy diversion tube seat to air-flow.
The speed that present weft yarn leaps the reed groove reaches more than 120 meter per seconds; The speed that arrives the auxilliary gaseous blast of weft yarn flight path adjacent domain must meet or exceed 120 meter per seconds on the component of weft yarn heading, because the speed of weft tracting flow can not be lower than the weft yarn flying speed.Therefore, be necessary to confirm to be suitable for the wefting insertion groove optimum shape and the size of 120-150 meter per second speed through simulated test.
Summary of the invention
The object of the invention purport is that air-jet loom provides a kind of simulation wefting insertion guiding gutter gas flow measurement system, surveys the relation of air-flow in size, shape and the tube seat of wefting insertion water conservancy diversion tube seat with analog detection method, and searching is more suitable for the water conservancy diversion tube seat of the high flying speed of weft yarn.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention realizes through following technical scheme:
A kind of simulation wefting insertion guiding gutter gas flow measurement system; Comprise the water conservancy diversion tube seat, said water conservancy diversion tube seat, said water conservancy diversion tube seat be furnished with two or three pilot jets in a lateral direction; Said pilot jet all is connected on the auxilliary jet flow control system; Be placed with pneumatic sensor in the inner chamber of said water conservancy diversion tube seat, said pneumatic sensor connects transmitter, and said transmitter connects storage oscillograph.
Further, said water conservancy diversion tube seat is fixed on the workbench through water conservancy diversion tube seat carriage, and described two or three pilot jets are fixed on the said workbench through the pilot jet carriage.
Further; Said auxilliary jet flow control system comprises source of the gas, gas bag, pressure regulator valve, electromagnetic valve and control panel; Described two or three pilot jets all connect said pressure regulation bag through said electromagnetic valve; Said pressure regulation bag connects said gas bag, and said gas bag connects source of the gas, and said control panel connects the opening and closing time that said electromagnetic valve is used to control electromagnetic valve.
Further, the inner chamber of said water conservancy diversion tube seat is used for ventilation stream, comprises upper wall, lower wall and inwall, and said inwall is processed with some slits that are parallel to each other, and said slit Working position is up to upper wall and lower wall.
Further, the height of said inner chamber is that the width of 4-5.5mm, upper wall is that the width of 6-9mm, lower wall is 4-7mm.
Design principle of the present invention is following:
Relatively move in wefting insertion water conservancy diversion tube seat with pilot jet and pneumatic sensor, survey the velocity variations of air-flow in the tube seat, confirm the optimum size of water conservancy diversion tube seat.Change the injection siding-to-siding block length of pilot jet; Change the spacing between pneumatic sensor and the pilot jet; Thereby measure the relation that each factor and wefting slot airflow distribute, the relation of the optimal size of research water conservancy diversion tube seat and the injection of pilot jet forms the weft tracting flow field of saving flow most.
Beneficial effect of the present invention is following:
The wefting insertion groove is formed with the reed wire stack, makes difficulty, and the air-flow detection test is done with the wefting insertion water conservancy diversion tube seat of simulation by system therefore of the present invention.What weft traction flew is high velocity air, and air-flow is passed to weft yarn to self speed through frictional force, and the speed of air-flow must be higher than filling speed.With the relation of air-flow in size, shape and the tube seat of analog detection method detection wefting insertion water conservancy diversion tube seat, seek the water conservancy diversion tube seat that is more suitable for the high flying speed of weft yarn.
