Description
Technical Field
The invention relates to the technical field of water jet looms, in particular to a weft insertion system of a water jet loom and a debugging method thereof.
Background
The water jet loom uses water as weft insertion medium, and the jet water flow produces friction traction force to weft yarn to drive weft yarn into shed, and interweave with warp yarn to form fabric. The weft insertion system of the water spraying loom comprises a water pump, an inlet one-way valve arranged on the water inlet end of the water pump, an outlet one-way valve arranged on the water outlet end of the water pump, a water inlet pipe connected with the inlet one-way valve, a water outlet pipe connected with the outlet one-way valve and a nozzle connected with the water outlet pipe.
The working principle is as follows: when the pump cam of the water pump turns from a small radius to a large radius, the coupling rod moves leftwards under the drive of the pump cam rod, so that the pump spring of the water pump is compressed, negative pressure is formed inside the water pump, the inlet one-way valve is opened, the outlet one-way valve is closed, and water is sucked into the water pump. When the cam of the water pump suddenly drops from the maximum radius to the minimum radius, the plunger of the water pump rapidly moves rightward under the action of the pump spring, and the pressure is directly acted on the water column sucked into the water pump, at the moment, the inlet one-way valve is closed, the outlet one-way valve is opened, water is pressed out from the water pump, and then the water is sprayed out from the nozzle through the water outlet pipe.
In the process that the jet water of the nozzle drives the weft yarn to enter the shed, if the water pressure of the jet water is too small, the friction traction force born by the weft yarn is too small, so that the weft yarn can not be interwoven with the warp yarn into a fabric due to the reduction of the moving stroke of the weft yarn; if the water pressure of the sprayed water is too high, the friction traction force applied to the weft yarn is too high, and the weft yarn has certain elasticity, so that the quality of the fabric is affected due to excessive deformation of the weft yarn.
Therefore, in the process of driving the weft yarns to move by the sprayed water, on the premise that the weft yarns and the warp yarns are required to be interwoven into the fabric, the lower the water pressure of the sprayed water is, the better the water pressure is, and the weft yarns with different specifications are required to be driven by different water pressures of the sprayed water; in practical production, for convenience in processing, the water pressure of the sprayed water is usually selected to be properly increased so as to ensure that weft yarns and warp yarns with various specifications are driven to be interwoven into a fabric, and the quality of the weft yarns is affected.
