Latitude pump.
Background technology:
The spring base upper sleeve of the picking pump of existing water-jet loom has helical spring, helical spring to exist
Easily vibrating in work process, the vibration of helical spring can cause the water that picking pump ejects
Flowing pressure is pulsed, and the water flow pressure ejected occurs pulsation then can affect the normal of weft yarn
Picking, is further improved.Meanwhile, spring base linear reciprocating motion in the course of the work,
There is larger gap between spring base and spring compressor, spring base is the most small to be rocked, and this also certainly will draw
Send out helical spring vibration, affect the normal discharge pressure of picking pump.
Summary of the invention:
The purpose of the present invention is aiming at the deficiency of prior art, and provides a kind of water-jet loom to throw
Latitude pump structure-improved, it devises the rubber cushion blocks vibration with reduction helical spring, reduces simultaneously
Gap between spring base and spring compressor reduces the vibration of helical spring, thus allows picking pump spray
Hydraulic pressure fluctuations out slows down.
The technology solution of the present invention is as follows:
Water-jet loom picking pump structure-improved, including the pump housing, the pump housing forms intake tunnel and
Exhalant canal, is provided with water feeding one-way valve in intake tunnel, be provided with water outlet list in exhalant canal
To valve, intake tunnel is connected with tank mutually by pipeline, and exhalant canal is sprayed with picking by pipeline
Mouth connects mutually, and water storage cylinder is spirally connected and is fixed on the pump housing, plunger sleeve in water storage cylinder, water storage cylinder
Sleeve is in spring base, and helical spring sleeve is on spring base, and spring compressor is screwed onto on the pump housing,
Helical spring and spring base are placed in spring compressor, and the right-hand member of helical spring is pressed in the rib of spring base
On, the left end of helical spring is pressed on rubber washer, and duct ring is nested with graphite block, spring base
Left end sleeve in duct ring, duct ring forms duct ring shade, rubber washer is pressed in duct ring cap
Along upper, duct ring shade is pressed on spring compressor；
Be fixed with connecting rod on plunger, connecting rod sleeve on spring base, connecting rod and the one end being connected sheet
Hinged, the other end connecting sheet is hinged with curved bar, and axle is passed through at the middle part of curved bar
Being hinged in frame, the front end of curved bar is fixed in frame, and the rear end of curved bar is provided with roller,
Roller leans against on eccentric, and eccentric is by motor-driven rotation.
Forming several caulking groove on the inwall of described duct ring, the graphite block of tile is embedded in this
In caulking groove.
The beneficial effects of the present invention is:
It devises the rubber cushion blocks vibration with reduction helical spring, reduces spring base and bullet simultaneously
Gap between spring cap reduces the vibration of helical spring, thus allows the current that picking pump ejects
Pressure fluctuation slows down.

Detailed description of the invention:
Embodiment: as shown in Fig. 1 is to 3, water-jet loom picking pump structure-improved, including the pump housing
1, the pump housing 1 forms intake tunnel and exhalant canal, intake tunnel is provided with into water list
To valve 2, being provided with out water one-way valve 3 in exhalant canal, intake tunnel passes through pipeline and tank
4 phases connect, and exhalant canal is connected with Weft insertion nozzle 5 phase by pipeline, and water storage cylinder 6 is spirally connected solid
Being scheduled on the pump housing 1, plunger 7 sleeve is in water storage cylinder 6, and water storage cylinder 6 sleeve is at spring base 8
In, helical spring 9 sleeve is on spring base 8, and spring compressor 10 is screwed onto on the pump housing 1, spiral shell
Rotation spring 9 and spring base 8 are placed in spring compressor 10, and the right-hand member of helical spring 9 is pressed in spring
On the rib 81 of seat 8, the left end of helical spring 9 is pressed on rubber washer 11, duct ring 12
On be nested with graphite block 13, the left end sleeve of spring base 8 is in duct ring 12, on duct ring 12
Forming duct ring shade 121, rubber washer 11 is pressed on duct ring shade 121, duct ring shade
121 are pressed on spring compressor 10；
Be fixed with connecting rod 14 on plunger 7, connecting rod 14 sleeve on spring base 8, connecting rod 14
Hinged with the one end being connected sheet 15, the other end connecting sheet 15 is hinged with curved bar 16
Together, the middle part of curved bar 16 is hinged in frame by axle 17, and the front end of curved bar 16 is solid
Being scheduled in frame, the rear end of curved bar 16 is provided with roller 18, and roller 18 leans against eccentric 19
