Problems solved by technology
[0005] However, with the gradual increase in speed of textile machines in recent years, when the number of revolutions of textile machines reaches 1000RPM or higher, only the above-mentioned method of clamping and filling the buffer element at the end of the spring will be somewhat stressful. end to cut off the vibration generated on the spring, that is, the vibration is transmitted through the plunger core and the pump body to improve its reducing effect, but it cannot sufficiently suppress the resonance of the spring itself
Because the active part of the spring end is filled with cushioning elements, or the resin-coated wire is used, these methods are intended to obtain a negative vibration damping effect with a complete cushioning effect. Although it can play a buffering role in easing the impact, it does not may attenuate its vibrations completely

Embodiment Construction
[0042] figure 1 It is a cross-sectional view of the spring 5 inserted into the elastic element 12 between the wire rods and installed on the pump device 30, which shows the positional relationship between the spring 5 and the elastic element 12 before the nozzle 6 sprays water; figure 2 It is a cross-sectional view of the pump device 30 showing the positional relationship between the spring 5 and the spring element 12 after spray water is sprayed from the nozzle 6 .
[0043] First refer to figure 1 , In the outer cover 21 of the pump device 30, the flow path 22 connected with the outer cover is intersected, and a cylinder 24 connected to it is placed in the flow path 22, and a freely sliding plunger core 3 is embedded in the cylinder 24.
[0044] From the supply source of the waterway outside the figure and the water storage buoy 4 that maintains a certain water level, water is sucked into the flow path 22 of the pump device 30 by means of the pipeline 20b and the reverse va...

The invention relates to a pump apparatus for liquid jetting loom machine. The objective is to ensure the prevention of pulse-flow of the jetting water by surely inhibiting the resonance of the spring of a pump, when the operation of a loom machine is speeded up. In a pumping mechanism 30 for feeding injection water to a water-jet loom by energizing a spring 5, as it is accompanied by the inhalation motion of the plunger, and allowing the plunger 3 to feed the injection water to the weft-inserting nozzle by the elastic force of the energized spring 5, a resonance inhibitor is attached to positively inhibit the spring wire 5a from resonating at a prescribed timing, particularly when the spring 5 is compressed.
Description
technical field [0001] The present invention belongs to the water-jet textile machine, which spits out the water of the weft through the energy-stored spring rebound force. When the textile machine is at a high speed, it eliminates the pulsation caused by the water spray by means of spring resonance. The device It is the relevant pump device in the textile machine. Background technique [0002] In the past, the water-jet textile machine pump device connected the pump to the main shaft of the textile machine, and the plunger core was driven by the cam push rod introduced into the rotating cam, and the water stored in the float tank was sucked in by the reverse valve on the suction side. Water, with the inhalation action of the plunger core, the spring in the pump body gradually stores energy, and after the specified time, the plunger core is urged to discharge through the spring that has stored energy, and then the reverse direction of the discharge side is used to discharge ...
