Embodiment

[0021] Such as figure 1 As shown, the principle of the water spray pump of the present invention is as follows: during the rotation of the cam 3 from a small radius to a large radius, the rotor of the angular lever 1 is pressed to rotate clockwise around the axis of the angular lever, driving the connecting rod 14 and the connected piston 8 outward. (i.e. the left side in the figure) moves, and the spring inner seat 6 fixed on it is pulled to slide along the cylinder liner 7 surface, and the spring 5 is compressed. At this time, due to the negative pressure, water passes through the space between the water inlet valve 10 piston and the cylinder liner in the pump body from the water tank 16 to realize the process of "pumping water".

[0022] When the cam 3 rotates from a large radius to a small radius, the rotor of the angular lever 1 can rotate counterclockwise around the axis of the angular lever due to the decrease of the radius. Due to the release of the elastic potential e...

Abstract

The invention discloses a water-jet loom weft insertion pump with adjustable water pressure. The invention adopts an intermittent toothed belt-type transmission angle rod rotation mode, which has the advantages of stable machine movement, high reliability, and high transmission efficiency. It has good maintenance-free performance, easy installation and debugging, and can adjust the swing range of the angle rod, thereby adjusting the stroke of the piston relative to the cylinder liner, thereby changing the compression amount of the spring, and achieving the purpose of adjusting the water pressure.

Description

technical field [0001] The invention belongs to the water-jet loom in the textile field, and in particular relates to a water-jet loom weft insertion water pump with adjustable water pressure. Background technique [0002] The water-jet loom is suitable for the weaving of chemical fiber filament fabrics. The weft yarns are drawn by high-pressure water flow through the shed to realize weft insertion weaving. [0003] Since the shape of the outer contour of the cam color is fixed, the water pressure cannot be adjusted by changing the compression amount of the spring arbitrarily. In actual production, the water pressure also needs to be adjusted due to the change of the fabric width, such as the width of the fabric is reduced. The water pressure will be reduced correspondingly to save energy, and the fabric width will increase, so the water pressure will increase. Otherwise, the weft insertion will not be able to reach the end or be delayed due to insufficient water pressure. ...
