Description
Technical field
The invention belongs to a kind of parts of chemical fibre main frame, be specifically related to a kind of metering pump
Background technique
The glue feeding opening of original square metering pump and glue discharging opening all are arranged on the inner cover plate, all near driving and driven gear, this metering pump with must increase a pump housing plate being connected of spinning main frame and come transition to connect, the connection of pump takes up room greatly.Original square metering pump for the vinylon spinning machine, the plastic washer end face seal is adopted in the driving shaft sealing of pump, and axle head spinning solution leakage phenomenon is serious.The kind of drive of original metering pump driving gear is a transmission shaft transmission driving shaft, and driving shaft connects driving gear by the key Spielpassung and rotates, and the driving gear of this kind of drive rotates steady inadequately, causes the metering pump spinning inhomogeneous.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of and directly is connected with the spinning main frame into and out of the glue hole, and the leakage of spinning solution can be avoided or reduce to compact structure, the self-control pump shaft directly with being connected of pin key, the gear transmission that reduces pump is stationarity not.
Technological scheme of the present invention: a kind of metering pump, it comprises outer cover plate 1, intermediate plate 2, inner cover plate 3, driving shaft 4, driving gear 5, driven gear 6, driven shaft 7, pin key 8, axle bed 9, pump shaft 10, nut 11, sealing gasket 12, screw 13, seal ring 14, dust plug 15, glue feeding opening 16, glue discharging opening 17, snout cavity 18, outlet plenum 19, the first technology inclined holes 20, the second technology inclined holes 21; Outer cover plate 1, intermediate plate 2, inner cover plate 3 connects by screw, and axle bed 9 and inner cover plate 3 are connected by screw; Be provided with pump shaft 10 in the axle bed 9, intermediate plate 2 is provided with driving shaft 4, driven shaft 7, and driving gear 5, driven gear 6, outer cover plate 1, inner cover plate 3 are provided with screw 13 and sealing gasket 12, also are provided with dust plug 15; Pump shaft 10 is provided with seal ring 14 and nut 11, the left end of pump shaft 10 is connected with driving shaft 4, driving shaft 4 upper supports have driving gear 5, driving gear 5 and pin key 8 interference fit, the arc groove Spielpassung of opening on pin key 8 and pump shaft 10 steps, outer cover plate 1 is provided with glue feeding opening 16 and snout cavity, and inner cover plate 3 is provided with glue discharging opening 17 and outlet plenum.Described glue feeding opening 16 is connected with snout cavity 18 by the first technology inclined hole 20, and described glue discharging opening 17 is connected with outlet plenum 18 by the second technology inclined hole 21.
The present invention has adopted directly being connected with the spinning main frame into and out of the glue hole of metering pump, made being connected of driving gear in pump shaft and the pump by oneself, pump structure compactness not only, occupy little space, the Utilization ratio height, and can avoid or reduce the spinning solution leakage, the gear transmission that has better guaranteed metering pump is steadily with flexible.

Embodiment
A kind of metering pump, it comprises outer cover plate 1, intermediate plate 2, inner cover plate 3, driving shaft 4, driving gear 5, driven gear 6, driven shaft 7, pin key 8, axle bed 9, pump shaft 10, nut 11, sealing gasket 12, screw 13, seal ring 14, dust plug 15, glue feeding opening 16, glue discharging opening 17, snout cavity 18, outlet plenum 19; Outer cover plate 1, intermediate plate 2, inner cover plate 3 connects by screw, and axle bed 9 and inner cover plate 3 are connected by screw; Be provided with pump shaft 10 in the axle bed 9, intermediate plate 2 is provided with driving shaft 4, driven shaft 7, and driving gear 5, driven tooth outer cover plate 1, inner cover plate 3 are provided with screw 13 and sealing gasket 12, also are provided with dust plug 15; Pump shaft 10 is provided with seal ring 14 and nut 11, the left end of pump shaft 10 is connected with driving shaft 4, driving shaft 4 upper supports have driving gear 5, driving gear 5 and pin key 8 interference fit, the arc groove Spielpassung of opening on pin key 8 and pump shaft 10 steps, outer cover plate 1 is provided with glue feeding opening 16 and snout cavity 18, and inner cover plate 3 is provided with glue discharging opening 17 and outlet plenum 19.Described glue feeding opening 16 is connected with snout cavity 18 by the first technology inclined hole 20, and described glue discharging opening 17 is connected with outlet plenum 19 by the second technology inclined hole 21.
Working procedure
It is that two dome by glue feeding opening 16, glue discharging opening 17 are fixed on crane span structure are chewed that metering pump is installed, and the transmission of pump is by spinning machine upper transfer gear transmission pump shaft 10, and pump shaft 10 directly drives the rotation of metering pump driving gear.For preventing that the pump shaft axle head from leaking, axle head is furnished with seal ring 14 and nut 11.The outer cover plate 1 of pump and inner cover plate 3 provide the enclosed cavity of sealing for intermediate plate 2, intermediate plate is placed driving gear 5, driven gear 6, gear engagement forms the snout cavity 18 and outlet plenum 19 zones (dotted line is represented to import and export) of sealing, turn round by gear, solution is under the conveying of inlet pressure, solution constantly is transported to outlet plenum from snout cavity, extrudes outside the pump.All there is a processing technology inclined hole on inner cover plate, outer cover plate top in addition, are used to be communicated with glue discharging opening 17, the outlet plenum 19 that glue feeding opening 16, snout cavity 18 and gear engagement form; When pump without use, enter in the pump for preventing dust, enter the glue discharging opening and need place dust plug 15.
