Description
Technical field
The present invention relates to charging gear applied technical field, especially a kind of fluid charging gear.
Background technique
Currently, being to have difference defeated to the device that various atmospheric pressure or under pressure systems carry out feeding operation for fluid foods
The various pumps of pressure out.Well known method is that the fluid foods transmitted are automatically flowed into or are inhaled into pump, is then forced out pump
Enter material feeding system afterwards.But such charging gear at least has the drawback that one, the material transmitted directly with pump
Contact, brings particular/special requirement to the material of the related part of pump, there may come a time when to be difficult to take into account the requirement for pumping function itself to material
The requirement for losing or avoiding material to corrosion of pump etc. to material is avoided pollution or avoided with by transmission material；Two, even if not having
The situation for having material selection difficult, when for needing to transmit there are many material, from when material cross staining and reduction being avoided to wash pump
Between and processing washes consider, it is desirable that preferably every kind of material is equipped with dedicated pump, results in higher equipment investment and fortune in this way
Row maintenance cost etc..For example, different material will be added in industrial or laboratory into reaction vessel, it may be difficult to find while have
There is the pump of suitable function and material, or every kind of material is needed specially to match a pump；When medically with syringe pump to patient fluid infusion, infused
The limitation of emitter volume, there may come a time when to need to change syringe multiple, increase management cost and opportunities for contamination；Height used in laboratory
Pressure liquid chromatography, a seed type are to provide the highly pressurised liquid of regime flow by syringe pump for system, due to pump itself directly with
Flowing is in contact, and is not easy when thus proposing higher requirement to the material of pump and volume structure etc., and changing mobile phase
Cleaning；The prior art is not able to satisfy the needs of people, the present invention is intended to provide a kind of fluid charging gear makes up existing skill in turn
The deficiency of art.
