Description
Technical field
The utility model is related to field of mechanical technique, specially a kind of multichannel column pump plug device.
Background technology
All it is at present mechanical connection in the plunger of the plunger pump used and feed screw nut, since plunger need to do standard in the pump housing
The leading screw and nut mechanism connection position line of true linear motion, driving must just be overlapped with the position line of pump housing plunger, otherwise be transported
It will be unsmooth when dynamic or even suppresses dead.Such mechanical mechanism requirement on machining accuracy is high, and cost is also high.And in order to avoid axis
It is misaligned suppress dead phenomenon, can only the XY axis directions on feed screw nut use free floating bindiny mechanism, at this moment in Z axis
Just there is inevitable gap in direction, reduces the precision that plunger is moved in Z-direction, reduces the applicable model of driving device
It encloses.
Utility model content
The technical issues of the utility model solves is to overcome the deficiencies of existing technologies, and provides a kind of multichannel plunger pump dress
It sets.The multichannel plunger pump device has simple and reasonable, small light weight, cheap, easy to use, is eliminating
On the basis of previous mechanical connection gap, and reduce part work in coordination required precision the advantages of, moreover it is possible to greatly improve plunger pump
Accuracy, stability, the precision of the flow of liquid supply rate, greatly extend the service life of pump, reduce the failure rate etc. of pump
Feature.
To achieve the above object, the utility model provides the following technical solutions：A kind of multichannel column pump plug driving device, including
Stepper motor, shell and the pump housing are installed with motor lead screw, the external spiral shell of the motor lead screw at the top of the stepper motor
Line is connected with feed screw nut, and magnet is symmetrically arranged at the top of the feed screw nut, and the top of the magnet is installed with
The cross section of magnetic guiding loop, the magnetic guiding loop is in dies, is plugged with plunger in the top groove of the magnetic guiding loop, institute
The equal nested encryptions in top for stating plunger have the pump housing.
Preferably, the motor lead screw, feed screw nut, magnet, magnetic guiding loop, plunger and the pump housing may be contained within the interior of shell
Portion, the stepper motor are located at the bottom of shell.
Preferably, the T-shaped structure in the cross section of the feed screw nut, and the bottom of feed screw nut offers and motor
The threaded hole that lead screw matches.
Preferably, the plunger and magnet are located at the upper and lower ends of magnetic guiding loop, and the bottom of plunger and magnet is transversal
Face area equation.
Compared with prior art, the utility model has the beneficial effects that：With simple and reasonable, small light weight,
It is cheap, easy to use, on the basis of eliminating previous mechanical connection gap, and reduces part and work in coordination required precision
The advantages of, moreover it is possible to the accuracy, stability, precision for greatly improving the flow of plunger pumping power greatly extend making for pump
With the service life, the failure rate of pump is reduced.
