Description

It is applicable to the high accuracy bull apparatus for metering liquid quickly produced
Technical field
This utility model relates to a kind of proportioning device, particularly relates to the high accuracy bull apparatus for metering liquid being applicable to quickly produce.
Background technology
The fast development of modern industry make fluid quantitative pump machinery, chemical industry, the energy, electronics, medicine and other fields application widely.Piston type quantitative pump is a kind of conventional fluid supply pump, generally it is made up of valve body valve rod etc. when its structure designs, complete fluid quantitative by valve rod reciprocating motion of the pistons in valve body to supply, forming negative pressure when pump rod retreats makes feed liquid be full of the pump housing, is then moved down the effect reaching dosed fluid supply by pump rod.But it is not tight that existing dosing pump generally exists sealing, and durability is low, and structure complex parts are more, it is difficult to the problems such as maintaining, inefficiency, and especially sealing difference makes dosing pump measuring accuracy poor with the most high multiple impact of pump rod mobile accuracy.The utility model proposes a kind of high accuracy bull apparatus for metering liquid used in quickly producing, by simplifying device inner structure, multi-layer sealed part can improve pump housing sealing property, feed liquid leakage rate is made to reduce, avoid lubricating oil to be mixed into feed liquid, reduce the external dust entrance pump housing and cause sealing variation to cause fault, use the high accuracy pump housing and servomotor simultaneously, the combination of multiple pump housings forms batch plant, provides indispensable hardware condition for realizing the supply of high-precision quantitative quick feed liquid.
Summary of the invention
The purpose of this utility model is, a kind of high accuracy bull apparatus for metering liquid being applicable to and quickly producing is provided, it is primarily adapted for use in the quantitative pumping of fluid under the quick production environment of production line, lubricating oil can be reduced and be mixed into feed liquid, reduce dust and enter the pump housing, the sealing property and the raising that improve device quantitatively pump precision, and bull metering improves production efficiency.
Technical solution adopted in the utility model is: the high accuracy bull apparatus for metering liquid being applicable to quickly produce includes: servomotor, line slide rail and support, plunger pump rod, pressure guide pin bushing, upper cover, axial sealing ring, sealing group ring, the quantitative pump housing, in high precision cylinder sleeve, mixed liquid pipeline assembly, support set, guide pin bushing, dosing pump lower pump body, discharging opening and charging aperture etc..Its technical scheme is: line slide rail, plunger displacement pump shaft bar, servomotor composition straight-line motion mechanism, provides power for dosing pump.The quantitatively pump housing and upper cover, the main body of lower valve body composition dosing pump, do straight reciprocating motion by dosing pump plunger pump rod the feed liquid in high accuracy cylinder sleeve to be discharged by discharge gate, on pump rod, it is sequentially provided with two groups of K-type oil sealings, combination sealing, sealing group ring 2, sealing group ring 1, guide pin bushing and multiple O-ring seal simultaneously, avoid the situations such as leakage, dust intrusion.
According to described composition, multi-stage sealed combination includes upper cover, K-type oil sealing, combination sealing, sealing group ring 2 and sealing group ring 1, is sequentially located at from top to bottom between pump rod and pressure guide pin bushing, plays the effect preventing leakage.Feed liquid in cylinder sleeve can quantitatively be pumped out by described plunger head with cylinder sleeve mating reaction.Charging aperture is connected with storage tank, and lower pump body top discharge mouth is connected with filter, and multiple pump housing combined runnings realize one action, the high efficiency production of parallel production.Have and improve quantitative accuracy, reduce environmental disruption that leakage causes, improve the feature such as production efficiency.
This utility model has the advantage that with good effect: described in be applicable to the high accuracy bull apparatus for metering liquid simple in construction that quickly produces, component part is few, use servo-control system, multi-stage sealed combination and vacuum cycle feed design, production cost can be reduced, ensure vacuum environment in pump, improve the sealing property of device, improve measuring accuracy and the work efficiency of device.
Accompanying drawing explanation
Shown accompanying drawing is structure of the present utility model and principle schematic.
Wherein: Fig. 1 dosing pump overall structure and principle schematic, Fig. 2 dosing pump pump body structure and principle schematic.
Detailed description of the invention
Principle of the present utility model and structure is further illustrated below in conjunction with accompanying drawing and by embodiment.It is applicable to the high accuracy fluid quantitative pump quickly produced, its concrete structure consists of: ball-type elevator (1) and servomotor (2) are fixed on servo control mechanism support, and the frame (3) consisted of with linear bearing and dosing pump support optical axis is connected with dosing pump pump rod (6), dosing pump lower pump body (17).Dosing pump upper cover (7) is fixed on pressure guide pin bushing (8) upper end, and dosing pump upper cover (7) plays axial compression effect with K-type oil sealing (9), combination sealing (10), sealing group ring 2 (11), sealing group ring 1 (12) and the guide pin bushing (13) being sequentially provided with inside of threadeding of pressure guide pin bushing (8).The height of upper cover can be regulated when seal combination is by mild wear, again realize the sealing of device, improve its anti-wear performance and service life, closely cooperate and strengthen, in order to reach multi-sealed part and pump rod, the effect sealed.Pressure guide pin bushing is threadedly attached to the quantitative pump housing (15) upper end, support set (14) and cylinder sleeve (16) can be pressed in the dosing pump main body that the quantitative pump housing (15) and dosing pump lower pump body (17) form, it is ensured that the location of cylinder sleeve (16).
During quantitative feeding, pumped by the pump rod (6) on servomotor (2) rotational band straight-line motion mechanism.Pump rod (6) lower end is positioned at support set (14) intracavity, is linearly moved to downwards move to cylinder sleeve (16) bottom, cylinder sleeve (16) interior feed liquid is the most quantitatively pumped out.Move back into original position then up, under the effect of negative pressure, feed liquid at support set (14) charging aperture is drawn onto in cylinder sleeve (16) intracavity, wait that feed liquid is pumped out by subsequent cycle.Dosing pump parallel join can be realized bull quantitative feeding, to improve production efficiency.
