Embodiment
Below in conjunction with accompanying drawing, structure of the present utility model is further described.
Referring to Fig. 1 and Fig. 2, radially bulb plunger pump of a kind of mesohigh, 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 utility model is bulb plunger pump radially, in the time that driven by motor rotor rotates, bulb plunger in cylinder hole also rotates with rotor, in the time that 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, in the time that 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, in the time that 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 the liquid that combined pressure goes out to flow according to the direction of regulation.If think augmented flow, can complete by the number that increases bulb plunger.Mesohigh of the present utility model 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 utility model 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 utility model effectively reach aforementioned model utility object.The friction pair of friction pair, plunger and the stator track curve composition of friction pair, pintle and the rotor composition of bulb plunger and cylinder hole composition is all sprayed WC pottery, and all ceramic surfaces are all used diamond lap, to reach required dimensional accuracy and surface accuracy.
