Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a water pump connecting disc structure for a water jet loom. Background Art

[0002] The water jet loom uses water as the weft insertion medium. The water jet generates frictional traction on the weft yarn, driving the weft yarn into the shed and interweaving with the warp yarn to form a fabric. The weft insertion system of the water jet loom includes a plunger pump with a one-way valve installed at the inlet and outlet ends, an inlet pipe connected to the inlet channel of the plunger pump, an outlet pipe connected to the outlet channel of the plunger pump, and a nozzle connected to the outlet pipe. The plunger pump relies on the reciprocating motion of the plunger in the cylinder body to change the volume of the sealed working chamber to achieve liquid suction and liquid pressure; it has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment. CN208933591U discloses a double-spring weft insertion water pump for a water jet loom, wherein a water pump connecting rod is connected to a spring guide assembly through a connecting plate and a joint, so that the movement of the water pump connecting rod acts on the water pump. In the prior art, the connecting plate is mostly a sheet structure with low strength. The fastening bolt and the connecting plate will vibrate during the operation of the water pump connecting rod, resulting in poor force conduction performance and uneven water spray from the water pump.
