Abstract
An airless spray pump (10) is provided with a single-acting piston pump which allows the use of a low-cost yoke (30) drive. Motor and pump shaft are offset for most efficient force utilization.
Description
Technical field
The present invention relates to be used to spray the vacuum jet pump of pigment and other coating.
Background technique
The vacuum jet pump that is used to spray pigment and other coating by vacuum method is well-known, and is generally divided into two types, promptly is used for the diaphragm pump of low market purpose and is used for the reciprocating piston pump of higher purpose.
Summary of the invention
A vacuum jet pump has a single action piston pump, and it allows yoke driving cheaply of use.In order to utilize power most effectively, motor and pump shaft are setovered.Main drive shell has a motor that is installed to its rear.A gearing uses the gear teeth that are formed with one 5 ° helix angle and have one 25 ° pressure angle.This geometrical shape combines the vertical cut gear of greater efficiency and the noise reduction that with the helical design is feature.
The present invention proposes a kind of by the vacuum jet pump that revolution motor drove with small gear, comprising: a single action piston pump-unit, and it has a pump rod; A drive gear arrangement, it comprises one with the gear of this pinion be arranged on eccentric on the described gear; A bearing means that is arranged on around the described eccentric; A yoke that reciprocally is arranged on around the described bearing means; A harder cover, its be connected on the described pump rod with described yoke in so that contact described bearing means.
An eccentric is molded into the front of gearing and is provided with a bearing means around it, and described bearing means is in yoke.Yoke vertically moves on guide rod, and these guide rods remain in the groove of drive shell.Yoke is molded from plastic into, and is the same with gearing, causes lower cost and simpler manufacturing.
Pump rod has a cover that is positioned on its top, and it has bearing.Pump-unit is designed to a kind of single-acting pump, that is to say, pump is only in the downward stroke pumping and at the up stroke pressurized.This element of allowing the chain that comprises yoke and gear is lighter, this be since yoke as a guide device rather than a force application device.
Motor and small gear depart from the center line of pump-unit.This set is without any special cantilever, and this is owing to pump rod, yoke, eccentric are positioned on the identical plane entirely with cover.Bar and single-acting pump have reduced the axial load that acts on the yoke with respect to the position of Gear center line.Small gear is offset partly in the position on the gear and has reduced the pumping action power that acts on gear shaft and the bearing.Can eliminate pumping force by intermediary element, as the transmission of yoke by capacity eccentric bearing being set directly at the pump rod cover end that is press-fitted, this provides long life-span, efficient and has allowed the yoke device that manufacturing is not really expensive.
The axle containment device is sealed housing by one and is constituted, and it is screwed into pump case and comprises a gasket element, and this element soaked with inlet seal oiling agent or other solvent or oiling agent.One folded V-type package is by the waved spring compression set, and it is fixed by seal casinghousing is fastened in the pump case.
Inlet valve (check) has a valve ball and a valve seat, and valve seat is pressed in the valve chest and with a holder and locatees.These elements are press-fitted each other so that whole device only is screwed into the main pump housing to replace.Similarly, the outlet valve device is made up of an outlet valve housing, and it is screwed in the pump case and has the valve ball of locating by a holder equally.Outlet passage with respect to the pump shaft line at angle.This allows that the outlet valve device substantially by gravity operated and only require boring and a passage is set, keeps vertical substantially ball-seat to concern simultaneously.
Can make these and other purpose and advantage of the present invention show more comprehensively from description below in conjunction with accompanying drawing, wherein in several diagrammatic sketch similarly reference number represent same or analogous parts.

Embodiment
The present invention is marked by label 10 usually, and it comprises a main drive shell 12, and this housing has a motor 14 that is installed to its rear portion.A gearing 16 with a rear bearing 17 and gear teeth 22 is inserted in the bearing housing 20 of drive shell 12.Tooth on the small gear 24 of the gear teeth 22 on the gearing 16 and motor 14 ends cooperates.Tooth on gear 22 and the small gear 24 is formed with one 5 ° helix angle and has one 25 ° pressure angle.This geometrical shape combines the vertical cut gear of greater efficiency and the noise reduction that with the helical design is feature.
An eccentric 25 is molded into the front of gearing 16 and is provided with a bearing means 28 around it, and described bearing means is in a yoke 30.Yoke 30 vertically moves on guide rod 32, and these guide rods remain in the groove 34 of drive shell 12.Yoke 30 is molded from plastic into.Gearing 16 is formed by the ZA-12 casting, has the balancer weight of an one, causes lower cost and simpler manufacturing.
As can see from Figure 2, motor and small gear 24 depart from the center line of pump-unit 40, and it also departs from bearing 20 in the opposite direction.In addition, this set is without any special cantilever, and this is owing to pump rod, yoke, eccentric are positioned on the identical plane entirely with cover.Bar and single-acting pump have reduced the axial load that acts on the yoke with respect to the position of gear eccentric.Small gear is offset partly in the position on the gear and has reduced the pumping action power that acts on gear shaft and the bearing.Can eliminate pumping force by intermediary element by capacity eccentric bearing being set directly at the pump rod cover end that is press-fitted, as the transmission of yoke, this provides long life-span, efficient and has allowed the yoke device that manufacturing is not really expensive.
As shown in Figure 4, an axle containment device 44 is sealed housing 46 by one and is constituted, and it is screwed into pump case 48 and comprises a gasket element 50, and this element soaked with inlet seal oiling agent or other solvent or oiling agent.One folded V-type package 52 is by waved spring compression 54 location, and it is fixed by seal casinghousing 46 is fastened in the pump case 48.
See Fig. 7 again, inlet valve 56 has a valve ball 58 and a valve seat 60, and described valve seat is pressed in the valve chest 62 and by the ball guide member 64 of holder and one and locatees.These elements are press-fitted each other so that whole device only is screwed into main pump housing 48 to replace.Similarly, the outlet valve device is made up of an outlet valve housing 60, and it is screwed in the pump case 48 and has the valve ball 62 of locating by ball seat 65.As can see from Figure 7, outlet passage 66 with respect to the axis of pump rod 36 at angle.This allows that outlet valve device 58 substantially by gravity operated and only require to be provided with a passage, keeps vertical substantially ball-seat to concern simultaneously.
Fig. 8 and Fig. 9 express the filter device 80 of making a slip of the tongue, and it comprises a filter cell 82 in the passage 84 that is contained in pump-unit 40 and fixing by counterpart 86.
See Figure 10 again, inlet duct 70 has a female threaded pipe end 70a.Inlet filter screening arrangement 72 has a pin end 72a, is used for cooperating with female threaded pipe end 70a.End 70a and 72a use size and the screw thread identical with public water pipe, so the user only needs to remove screening arrangement 72, public water pipe are connected to inlet duct 70, the also Rinsing unit of fetching boiling water.
Be appreciated that under the prerequisite of the spirit and scope of the present invention that do not depart from the claims qualification and can carry out various changes and modification vacuum jet pump.
