Abstract
The invention relates to a middle and high-pressure radial pump with ballhead plungers. The middle and high-pressure radial pump comprises a stator and a rotor which are inside a pump body, a flow-distribution shaft which is in close fit with the conical surface of the rotor, an end cover, a joint, a transmission shaft, an axial positioning device, a plug, as well as the ballhead plungers which are clung to the inner cavity of the stator and the bore hole of the rotor, wherein an arc-shaped elliptical orbit is arranged on the inner wall of the stator; the end cover is fixedly connected with the stator through bolts; the rotor is connected with the transmission shaft of the pump through splines; the quantity of the ballhead plungers is plural; a seal ring is arranged inside the end cover; a round nut for compressing the end cover and the seal ring is arranged on the end cover; in the axial positioning device, the transmission shaft is clung to the inner surface of the rotor through bolts, and thus the rotor and the transmission shaft form an integral whole. The middle and high-pressure radial pump is compact in structure, and can obviously improve the sealing property and reduce mechanical vibration through the ballhead plungers. The sealing length of the middle and high-pressure radial pump is great, so that the middle and high-pressure radial pump can realize middle and high-pressure transportation in a low-viscosity medium such as water.
Description
Technical field
The present invention relates to radially bulb plunger pump of a kind of mesohigh.
Background technique
Ball piston pump is to take the radial pump that spheroid is piston, its radial dimension is significantly smaller than the radial plunger pump in equal cylinder hole, simultaneously, the rolling of spheroid has replaced the slip of cylinder, has reduced friction, has improved lubricated, but bulb stopper pair belongs to linear sealing, seal length is almost nil, and sealing difficulty is large, can not realize mesohigh and high volumetric efficiency under aqueous medium.
Summary of the invention
Object of the present invention, for low viscosity media such as water, for realizing wherein high-pressure delivery, proposes a kind of compact structure, and the mesohigh that can obviously improve sealing and reduce mechanical vibration is bulb plunger pump radially, to overcome the deficiency of above-mentioned ball piston pump.
For achieving the above object, technological scheme of the present invention is:
A bulb plunger pump radially, its special way is: the pintle that comprises stator in the pump housing, rotor, fits tightly with rotor inner conical surface, end cap, joint, transmission shaft, axial direction positioning device, screw plug, with the bulb plunger of the cylinder hole laminating of bore of stator and rotor; The inwall of stator is provided with circular arc elliptical orbit, and end cap and stator are bolted to connection, and rotor is connected with the transmission shaft of pump by spline; The quantity of described bulb plunger is even number; In described end cap, seal ring is set, on end cap, is provided for compressing the round nut of end cap and seal ring; Described axial direction positioning device is adjacent to transmission shaft and rotor inner surface by bolt, makes rotor become as a whole with transmission shaft.
Further, the quantity of described bulb plunger is 6 or 8.
Further, described stator is maintained static and is connected with motor by bolt, and the transmission shaft of pump is connected by coupling with the output shaft of motor.
The invention provides radially bulb plunger pump of a kind of mesohigh, its compact structure, can obviously improve sealing and reduce mechanical vibration and use bulb plunger, and radially bulb plunger pump seal length is long for this mesohigh, under the low viscosity media such as water, also can realize mesohigh and carry.

Embodiment
Below in conjunction with accompanying drawing, structure of the present invention is further described.
Referring to Fig. 1 and Fig. 2, a bulb plunger pump radially, the pintle 3 that comprises stator 1 in the pump housing, rotor 2, fits tightly with rotor inner conical surface, end cap 5, joint 6, transmission shaft 10, axial direction positioning device 8, screw plug 7, with the bulb plunger 4 of the cylinder hole laminating of bore of stator and rotor; The inwall of stator 1 is provided with circular arc elliptical orbit, and end cap 5 is bolted to connection with stator 1, and rotor 2 is connected with the transmission shaft 10 of pump by spline; The quantity of described bulb plunger 4 is even number; The interior seal ring that arranges of end cap 5, is provided for compressing the round nut 9 of end cap 5 and seal ring on end cap 5; Described axial direction positioning device 8 is adjacent to transmission shaft 10 and rotor 2 internal surfaces by bolt, makes rotor become as a whole with transmission shaft.
The quantity of bulb plunger 4 is 6 or 8.
Mesohigh of the present invention is bulb plunger pump radially, when driven by motor rotor rotates, bulb plunger in cylinder hole also rotates with rotor, when rotating speed reaches certain numerical value, at centrifugal force, under the acting in conjunction of the reaction force of hydraulic coupling and stator, bulb plunger is made ellipse circular movement along rail in stator, when bulb plunger is rotated to the major semi axis of elliptical orbit by the semi-minor axis of elliptical orbit, it is water absorption course, when bulb plunger is rotated to the semi-minor axis of elliptical orbit by the major semi axis of elliptical orbit, it is drainage procedure, and the effect of pintle is to make to suck liquid that combined pressure goes out to flow according to the direction of regulation.If think augmented flow, can complete by increasing the number of bulb plunger.Mesohigh of the present invention radially bulb plunger pump fixes joint by bolt, and screw plug is used for stopping that high-pressure medium is back in low-pressure cavity goes, and round nut is used for compressing the seal ring in end cap and end cap.Bulb plunger pump of the present invention relies on the structural characteristics that its bulb plunger and bulb plunger quantity are even number, make rotor system completely circumferentially symmetrical at pintle high low pressure chamber effect lower stress, can effectively reduce shunting mechanical vibration and noise, simultaneously according to active force and reaction force, the stressed of pintle is also circumferentially symmetrical, fluid oscillation and the noise that also can effectively reduce pintle shunting, make the present invention effectively reach aforementioned goal of the invention.The friction pair that the friction pair that the friction pair that bulb plunger and cylinder hole form, pintle and rotor form, plunger and stator track curve form is all sprayed WC pottery, and all ceramic surfaces are all used diamond lap, to reach required dimensional accuracy and surface accuracy.
