The specific embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
Referring to Fig. 1, the embodiment of the invention 1 provides a kind of pulsating flow generation device, and this device comprises the water tank 1 of depositing fluid working substance, some arms and driving mechanism 2; Wherein, some arms comprise first arm 3, second arm 4, the 3rd arm 5 and the 4th arm 6; This device also comprises the piston 7 that links to each other with driving mechanism 2 and is located at the tubing pump 8 on first arm 3; Wherein, water tank 1 links to each other with the input of first arm 3, second arm 4 and the 3rd arm 5 respectively; The output of second arm 4 and the 3rd arm 5 links to each other with first arm 3 and between the output of the tubing pump 8 and first arm 3; Be respectively equipped with check-valves 9 on the input of second arm 4 and the 3rd arm 5 and the output; The 4th arm 6 one ends are communicated with second arm 4, and the 4th arm 6 other ends are communicated with the 3rd arm 5; Piston 7 is located in the 4th arm 6, and is movably connected with the 4th arm 6 inwalls; Second arm 4 equates with the mouth of pipe sectional area of the 3rd arm 5.
Further, the mouth of pipe sectional area of first arm 3, second arm 4, the 3rd arm 5 and the 4th arm 6 equates.
Particularly, the pipeline between each arm itself, each arm connects and pipeline directly is connected with frame for movement, will adopt fastening means such as three-way connection well known in the art, four-way connection, bend pipe and bolt.Through the device that the embodiment of the invention 1 provides, can deposit liquid working substance in the water tank 1; The output of first arm 3 flows output ripple.When the mouth of pipe sectional area of first arm 3, second arm 4, the 3rd arm 5 and the 4th arm 6 equates; The flow resistance balance of fluid makes the pulsating flows of the arm 3 final outputs of winning more stable in first arm 3, second arm 4, the 3rd arm 5 and the 4th arm 6; Thereby the periodically pulsing of the feasible fluid that produces is more accurate.
Further, tubing pump 8 is for being used for regulating the frequency modulation tubing pump of first arm, 3 fluid flows.
Particularly, tubing pump 8 is used to export constant-pressure fluid.When tubing pump 8 is the frequency modulation tubing pump, can change the size of output flow in first arm 3 easily.In the embodiment of the invention 1, suppose that through rate of flow of fluid in first arm 3 be V0.
Wherein, driving mechanism 2 comprises motor 2a, is used to regulate speed governing unit 2b, decelerator 2c, cam 2d and the connecting rod 2e of motor 2a rotating speed; Motor 2a links to each other with speed governing unit 2b, decelerator 2c and cam 2d respectively; Cam 2d links to each other with connecting rod 2e one end; The connecting rod 2e other end links to each other with piston 7.
Particularly, driving mechanism 2 is used to the power that provides piston 7 to carry out straight reciprocating motion.Can regulate the rotating speed of motor 2a through speed governing unit 2b and decelerator 2c.In the embodiment of the invention 1, the rotating speed of supposing motor 2a is n.
Particularly, cam 2d links to each other with the main shaft of motor 2a, and connecting rod 2e one end and cam 2d are hinged and connected.After the motor 2a start, will drive cam 2d and rotate together.After the cam 2d rotation, drivening rod 2e is carried out straight reciprocating motion.Connecting rod 2e drives piston 7 simultaneously and moves together.Because piston 7 and the 4th arm 6 inwalls are movably connected, so, piston 7 will move back and forth by the axis direction along the 4th arm 6 in the 4th arm 6.
Particularly, the center of cam 2d is provided with a hollow elongated slot, and main shaft one end of motor 2a is fixed in this hollow elongated slot through latch-up structure.
Further, main shaft one end of motor 2a is provided with external screw thread, and this latch-up structure is a nut.During connection, cam 2d is enclosed within on this end of main shaft of motor 2a, and cam 2d and main shaft is fixed through the external screw thread on nut, pad and the main shaft.What be worth explanation is, in practical application, can be according to actual needs, and through the link position of this hollow elongated slot adjustment cam 2d and motor 2a main shaft, thus the eccentric distance of change cam 2d.

0+ V
1| sin (2 π nt) |.In addition, can also know that the frequency of fluid pulsation is f=2n, the amplitude of fluid pulsation is A=V
1/ (2V
0+ V
1).
Particularly, through regulating the rotation speed n of motor 2a, can regulate ripple frequency f; And after confirming frequency f, through changing the length of cam 2d eccentric distance and connecting rod 2e, can change piston 7 and move back and forth speed V
1Thereby, the amplitude A of regulating pulsating flow.Therefore, utilize the pulsating flow generation device that provides in the embodiment of the invention 1, can regulate the frequency and the amplitude of pulsating flow.
