Abstract
The utility model discloses a radial plunger pump, the interior circumference of shell sets up to the curvilinear figure, and under the same size scale, this song linear acceleration value is minimum, the biggest speed moreover, and the maximum pressure angle is all less relatively, the outside of annular high pressure chest is provided with the sealing washer, guarantees the relative stability of reset force, the outside of plunger is provided with the plunger case, plunger and plunger hole sliding connection can reduce the wearing and tearing of the working chamber of the plunger body to increase the life -span of pump, be provided with the pressure balance groove on the plunger rod, phenomenons such as reduction water hammer that can be fine and fatigue wear, this radial plunger pump has that stability is high, long service life's advantage, has wide market prospect.
Description
Technical field
The utility model relates to radial plunger pump apparatus field, is specifically related to a kind of radial plunger pump.
Background technique
Plunger pump relies on the to-and-fro motion of plunger body in active chamber and the Volume Changes that formed forms the working stroke of oil suction and force feed.Often the volume capacity of single plunger is too small, and plunger pump is all that several plunger body works together and increases to the flow of the pump housing.Namely plunger body is the change of working volume in the stroke change of active chamber, therefore very simply can change the discharge capacity of the pump housing, easily make variable displacement pump.Radial plunger pump is the plunger pump that the vibration-direction of piston or plunger is vertical with live axle.Radial plunger pump working principle: driving torque is passed to the hydraulic cylinder rotor of star by cross coupler by live axle, stator is not by other horizontal force.Rotor is contained on pintle.Be arranged in the plunger of the radial arrangement of rotor, be close to eccentric stroke stator by the piston shoes of static balance.Plunger is connected with slipper socket, and is locked by jump ring.Piston shoes are stuck on stroke stator by two retaining rings.
Model utility content
The purpose of this utility model is to provide a kind of radial plunger pump, optimizes traditional plunger pump, has that stability is high, the advantage of long service life.
For achieving the above object, the utility model provides following technological scheme: a kind of radial plunger pump, comprise the pump housing, the described pump housing is made up of shell, plunger, stator, and described shell is circle configurations, and can rotate, the center of the described pump housing is provided with annular high voltage chamber, and described plunger adopts symplex structure to be arranged on enclosure, is provided with plunger rod between described annular high voltage chamber and plunger, described stator is arranged between plunger rod, and stator and plunger are arranged off-centre.
Preferably, the inner circumference of described shell is set to curvilinerar figure, and the number of described curve is nine.
Preferably, the outer installment in described annular high voltage chamber has seal ring.
Preferably, the outer installment of described plunger has plunger case, and described plunger and plunger hole are slidably connected.
Preferably, described plunger rod is provided with relief groove.
The beneficial effect of above technological scheme is adopted to be: the utility model provides a kind of radial plunger pump, the inner circumference of described shell is set to curvilinerar figure, under identical size scale, this curve accekeration is minimum, and top speed, maximum pressure angle is all relatively little, the outer installment in described annular high voltage chamber has seal ring, ensure relative the stablizing of reposition force, the outer installment of described plunger has plunger case, described plunger and plunger hole are slidably connected, the wearing and tearing of the active chamber of plunger body can be reduced, thus increase the life-span of pump, described plunger rod is provided with relief groove, can be good at reducing the phenomenon such as water attack and fatigue wear, this radial plunger pump, there is stability high, the advantage of long service life, there are wide market prospects.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of radial plunger pump of the utility model;
Fig. 2 is the structural representation of the inner circumference of shell;
Wherein: circular curve, 8-seal ring, 9-plunger case, 10-relief groove in the 1-pump housing, 2-shell, 3-plunger, 4-stator, 5-annular high voltage chamber, 6-plunger rod, 7-.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
As shown in Figure 1, a kind of radial plunger pump, comprise the pump housing 1, the described pump housing 1 is made up of shell 2, plunger 3, stator 4, and described shell 2 is circle configurations, and can rotate, the center of the described pump housing 1 is provided with annular high voltage chamber 5, and it is inner that described plunger 3 adopts symplex structure to be arranged on shell 2, is provided with plunger rod 6 between described annular high voltage chamber 5 and plunger 3, described stator 4 is arranged between plunger rod 6, and stator 4 and plunger 3 are arranged off-centre.
In addition, as shown in Figure 2, the inner circumference of described shell 2 is set to curvilinerar figure 7, the number of described curve is nine, the outer installment in described annular high voltage chamber 5 has seal ring 8, the outer installment of described plunger 3 has plunger case 9, and described plunger 3 is slidably connected with plunger hole 9, and described plunger rod 6 is provided with relief groove 10.
Based on above-mentioned, the utility model provides a kind of radial plunger pump, the inner circumference of described shell is set to curvilinerar figure, under identical size scale, this curve accekeration is minimum, and top speed, maximum pressure angle is all relatively little, the outer installment in described annular high voltage chamber has seal ring, ensure relative the stablizing of reposition force, the outer installment of described plunger has plunger case, described plunger and plunger hole are slidably connected, the wearing and tearing of the active chamber of plunger body can be reduced, thus increase the life-span of pump, described plunger rod is provided with relief groove, can be good at reducing the phenomenon such as water attack and fatigue wear, this radial plunger pump, there is stability high, the advantage of long service life, there are wide market prospects.
As known by the technical knowledge, the utility model can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Allly all to be included in the utility model within the scope of the utility model or being equal to the change in scope of the present utility model.
