Description
Technical field
This utility model relates to a kind of high pressure constant flow pump, particularly a kind of integral modular high pressure constant flow pump.
Background technology
Chromatograph of liquid high pressure constant flow pump is mainly used in the solvent delivery of chromatograph of liquid, it is desirable to realizing the pulse free transmission of solvent, range of flow width, pressure height, to adapt to liquid chromatograph from analyzing preparation and the different demands prepared to scale.Traditional high pressure constant flow pump is mainly by the pump housing, exhaust-valve, pressure transmitter, driving motor and control circuit five part composition, and its middle pump body is key core part, and design requires and machining accuracy is high, including pump head, check valve, cam, guiding push rod, pump housing framework etc..Control to drive driven by motor cam to rotate by control circuit, it is achieved liquid carries.This high voltage and constant current pump structure is that a motor drives a pump head or two pump head work, the most once run into the situation needing amount of infusion bigger, then multiple constant flow pumps can only be used together, on the one hand there is problem with high costs, the most multiple constant flow pumps also can occupy bigger space, affects the placement of other equipment.
Summary of the invention
This utility model is to solve the above-mentioned deficiency existing for prior art, proposes one and uses modularized design mode, can carry out the integrated high pressure constant flow pump of pump head selection, assembling as required.
Technical solution of the present utility model is: a kind of integral modular high pressure constant flow pump, including carrying platform 1, it is characterized in that: on described carrying platform 1, be provided with motor 2, motor 2 is connected with camshaft 4 by gear driving pair 3, with described camshaft 4 match be provided with at least two set pump housing modules 5, described pump housing module 5 includes the cam 6 being connected on camshaft 4, described cam 6 is arranged in the pump housing 7, and described camshaft 4 bearing is bearing on the described pump housing 7, push rod 8 is slidably connected in each pump housing 7, one end of push rod 8 matches with cam 6, the other end of push rod 8 is then connected with the plunger in pump head 10 by plunger rod 9, spring also it is socketed with outside plunger rod 9, Outlet check valves 11 and inlet one-way valve 12 it is provided with on described pump head 10.
This utility model compared with the existing technology, has the advantage that
The integral modular high pressure constant flow pump of this kind of version, its simple in construction, design ingenious, rationally distributed, it for the constant flow pump of a traditional pump head or two pump head formulas in the presence of practical work process: cannot flexible combination configuration as required, the problems such as combination difficulty, design the structure of a kind of integral type, the pump housing being capable of medium pump function is used modularized design by it, and it can be facilitated, it is quickly mounted on carrying platform to form the integral structure of multiple pump heads, this structure can the quantity of unrestricted choice pump head as required, and too many cost will not be increased, and its entirety takes up room the most relatively small.And its processing technology is simple, cheap for manufacturing cost, it can be said that it has possessed multiple advantage, is particularly suitable for popularization and application in the art, and its market prospect is the most wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment pump housing module section.
Fig. 2 is the overall structure schematic diagram of this utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.nullSuch as Fig. 1、Shown in Fig. 2: a kind of integral modular high pressure constant flow pump，Including the carrying platform 1 based on，Carrying platform 1 is provided with motor 2，This motor 2 is rotated by gear driving pair 3 drive cam shaft 4，With this camshaft 4 match be provided with at least two set pump housing modules 5，Each pump housing module 5 includes a cam being connected on camshaft 46，Here cam 6 is positioned at the pump housing 7，And above-mentioned camshaft 4 is bearing on the described pump housing 7 by bearing，Push rod 8 is slidably connected in each pump housing 7，One end of this push rod 8 matches with cam 6，The other end of push rod 8 is then connected with the plunger being positioned at pump head 10 by plunger rod 9，Described pump head 10 is then fixedly connected on the pump housing 7，And it is additionally provided with Outlet check valves 11 and inlet one-way valve 12 on pump head 10.
The work process of the integral modular high pressure constant flow pump of this utility model embodiment is as follows: select the quantity of pump housing module 5 the most according to actual needs, then all of pump housing module 5 is fixed on carrying platform 1 side by side, and allowing camshaft 4 be connected with the cam 6 in all of pump housing module 5, preparation completes；
During work, start motor 2, motor 2 drives camshaft 4 to rotate by gear driving pair 3, and then drives cam 6 to rotate, under the common effect of cam 6 and spring, the push rod 8 matched with cam 6 will do reciprocal linear motion in the pump housing 7, and then promote the plunger in pump head 10 to move reciprocatingly, it is achieved discharge opeing and imbibition: when plunger moves to pump head 10 direction, Outlet check valves 11 is opened, inlet one-way valve 12 is closed, it is achieved discharge opeing；When plunger moves to the direction away from pump head 10, inlet one-way valve 12 is opened, and Outlet check valves 11 is closed, it is achieved imbibition；
By the difference at phase angle between multiple cams 6, realize the ripple compensation of flow, i.e. when (or one group) pump head 10 imbibition, another (or another group) pump head 10 discharge opeing, finally realize the low pulse of volume flow, stable transmission.
