Specific embodiment

The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation Example is only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common Technical staff's all other embodiment obtained without making creative work belongs to the model that the present invention protects It encloses.

Fig. 1 ~ Fig. 2 is please referred to, the embodiment of the present invention includes:

The linkage pumping mechanism for avoiding adverse current as shown in Figure 1, comprising: inlet tube 12, piston 20, the pump housing 2, connects outlet tube 16 Bar 21, push plate 8, pedestal 1, turntable 7, sleeve-type valve core 9, actuating arm 6 and rotation drive device 3, the pump housing 2 are horizontally set on On pedestal 1, it is fixed by bolts.

2 back-end closure of the pump housing and front end indent are provided with cavity corresponding with piston 20, and the setting of piston 20 exists In cavity, facilitate the movement of piston 20, the first sealing ring 19 corresponding with cavity inner wall is provided on the outside piston, is avoided Leakage problem.

The front end indent of the pump housing 2 is provided with to be extended with the body concentric annular groove 14 of chamber, 9 end of sleeve-type valve core Into annular groove 14, the annular groove oral area is provided with the second sealing ring 10 corresponding with sleeve-type valve core outer circle and inner wall, keeps away Exempt from the leakage of solution.The front end of sleeve-type valve core 9 is arranged in the push plate 8, is welded and fixed, stable structure.

The connecting rod 21 is arranged between 8 back side of push plate and piston 20, and sleeve-type valve core 9 and piston 20 are being pushed away It is moved synchronously under the action of plate 8.21 both ends of connecting rod can be welded with push plate 8 and piston 20 respectively, and sound construction can also push away Mounting-fixing base on plate 8 and piston 20 carries out the pin joint at 21 both ends of connecting rod, reduces assembling difficulty.

The front on pedestal 1 and being located at push plate 8 is arranged in the rotation drive device 3, and the setting of turntable 7 is driven in rotation On the output shaft of dynamic device 3, the rotation drive device 3 is reduction gearbox, and the input terminal of the reduction gearbox 3 is provided with motor progress Driving, motor can use servo motor, be driven by PLC controller, and running accuracy is high, can control the fortune of piston 20 Dynamic frequency realizes intermittent pumping, is conducive to the filling of solution.

Eccentric setting has drive rod 5 on the turntable 7, and 8 front end of push plate is provided with axis pin base 17, the actuating arm 6 It is arranged between drive rod 5 and axis pin base 17, the pin shaft for running through actuating arm 6 from thickness direction is provided on the axis pin base 17, Adapt to the swing of actuating arm 6.
