Abstract
The invention discloses a rotary piston oil pump, including: stator component, where the inner hole is columnar, and the middle of two side surfaces of the stator symmetric to the axis is made with oil inlet cavity and oil discharge cavity; rotor component, where the rotor is columnar, a piston is held in the side columnar hole and linked with one end of the link rod by piston pin, the other end rotates around a fixed point, the side surface of the stator or rotor is installed with sealing ring or groove or not, the rotary radius of the link rod is half of the rotor's, and the link rod or the rotor is linked with electric machine. When it works, the piston rotates all the time, so that there is no inertia force of reciprocating motion, it works stably and the noise is small. And it runs a circle to automatically complete charging and discharging oil without oil distributing disc. When the piston rotates a circle, it completes two pressure circulations. The piston is equivalent to two ones of reciprocating piston pump. It has good technical and sealing properties, and high integrative efficiency.
Description
Affiliated technical field
The present invention relates to oil pump, especially relate to a kind of rotary piston oil pump.
Background technique
Existing plunger pump, plunger are reciprocating motion type, owing to will overcome reciprocating inertial force, so energy consumption is big, operation is uneven, and noise is big.But also need oil distribution casing
Summary of the invention
The objective of the invention is to provide a kind of rotary piston oil pump.This pump when operation piston all the time in rotation, move a week, finish automatically into, oil extraction, need not oil distribution casing.Piston rotates a circle, and finishes two pressures cycle.
In order to achieve the above object, the technical solution used in the present invention is:
1) stator component: the endoporus of stator is cylindrical, and the middle part, stator bi-side that is symmetrical in axis has oil suction chamber, oil-discharging cavity;
2) rotor part: rotor is cylindrical, in the rotor side surface cylindrical hole piston is housed, the side of piston cylinder links with wrist pin and connecting rod one end, the connecting rod the other end rotates around a fixed point, seal ring and groove are housed on the cylindrical side of stator or the cylindrical side of rotor or seal ring and groove are not housed, the radius of gyration of connecting rod is half of rotor rotation radius, and the connecting rod the other end or rotor are connected with motor.
The present invention compares with background technique, and the useful effect that has is: rotary piston oil pump of the present invention, and as long as piston reasonable in design, does not just have reciprocating inertial force all the time in rotation when operation, operates steadily, and noise is little.And move a week, finish automatically into, oil extraction, need not oil distribution casing.Piston rotates a circle, and finishes two pressures cycle.It is equivalent to the effect of two plungers of reciprocating plunger pump.In addition, technology capability of the present invention is good, good seal performance.So the present invention is not only simple in structure, and the overall efficiency height.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is rotor and piston assembling schematic representation;
Fig. 3 is rotor, connecting rod and wrist pin assembling schematic representation;
Fig. 4 is an operation working principle schematic representation of the present invention.
Among the figure: 1 stator, 2 rotors, 3 pistons, 4 wrist pins, 5 connecting rods, one end, the 6 connecting rod the other ends, JJ ' oil suction chamber, PP ' oil-discharging cavity.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the present invention includes:
1) stator component: the endoporus of stator 1 is cylindrical, and the middle part, stator bi-side that is symmetrical in axis has oil suction chamber j, j ', oil-discharging cavity p, p ';
2) rotor part: rotor 2 is cylindrical, in the rotor 2 side cylindrical holes piston 3 is housed, the side of piston 3 cylinders links with wrist pin 4 and connecting rod one end 5, the connecting rod the other end 6 rotates around a fixed point, seal ring and groove are housed on the cylindrical side of the cylindrical side of stator 1 or rotor 2 or seal ring and groove are not housed, the radius of gyration o of connecting rod
1o
2 Be rotor 2 radius of gyration o
2Half of o, the connecting rod the other end 6 or rotor 2 are connected with motor.
Said oil suction chamber j, j ' and oil-discharging cavity p, p ' be symmetric arrangement or or asymmetric layout, or aperture equates, or aperture is unequal.
Operation working principle of the present invention is as follows: the motor driving connecting rod the other end 6 rotates, and connecting rod one end 5 drives piston 3 motions by wrist pin 4, and piston 3 drives rotor 2 rotations again.(Fig. 4 is a) time, and oil enters the S of grease chamber from oil suction chamber JJ ' when rotor 2 is in the oil-feed initial position.When rotor 2 rotations, oil continues to enter the S of grease chamber (Fig. 4 b) from oil suction chamber JJ '.When rotor 2 Rotate 180s were spent, oil-feed ended (Fig. 4 c), then just begins pressure oil output.When rotor 2 continues rotation, continue pressure oil output (Fig. 4 d), revolve three-sixth turn up to rotor 2, reach P point (Fig. 4 e), oil extraction finishes.This is a circulation, and subsequent is second circulation.As or arrange this and go round and begin again, continuous operation.Because the interlock of connecting rod one end 5, connecting rod one end 6, piston 3 and rotor 2, in entire work process, piston 3 is in rotation status all the time.When rotor 2 S of grease chamber one end oil-feed (oil), the other end Q oil extraction (or oil-feed) simultaneously (Fig. 4 a), on the contrary still.In other words, in fact a piston of the present invention is equivalent to the effect of reciprocating type two plungers.The present invention advances, oil extraction is determined by rotor 2 and position of piston fully.JJ ' the section of stator is oil-feed, and PP ' section is oil extraction, as shown in Figure 1.When rotor 2 rotates a circle, advance, the oil extraction process finishes automatically, therefore no longer needs to join oil.
