In this embodiment, as shown in fig. 2, the first suction and exhaust unit 01 and the second suction and exhaust unit 03 are different by half a cycle, when the suction and exhaust unit is working, the suction and exhaust component of the first suction and exhaust unit 01 starts sucking fluid through the piston 72, because the piston 72 pulls to generate a first negative pressure, the fluid flows into the piston cylinder 73, after the suction is completed for the first time, the piston 72 generates a pushing force, at the moment, a first positive pressure starts to exhaust the fluid, after the discharge is completed for the second time, when the first suction and exhaust unit 01 discharges, the piston 72 at the position of the second suction and exhaust unit 03 pulls to generate a negative pressure, and when the second suction and exhaust unit 03 finishes sucking, the piston 72 of the second suction and exhaust unit 03 generates a pushing force and generates a positive pressure, and discharges the fluid in the piston cylinder 73, and when the second suction and exhaust unit 03 discharges, the first suction and exhaust unit 01 starts to suck, and likewise follow the settings of the first time and the second time, and form a circulation suction and exhaust with half a cycle difference, so as to realize suction and exhaust synchronization.
In some embodiments, the absolute value of the first negative pressure and the first positive pressure are set equal.
In this embodiment, the first negative pressure and the first positive pressure set by the two suction and discharge units have the same absolute value, so that the same speed of fluid suction and discharge and the same pressure born by the pipeline are ensured.
In some embodiments, the first time and the second time are set equal.
In this embodiment, the set first time and the set second time set by the two suction and discharge units are the same, so that when one unit finishes pumping, the other unit finishes discharging, and half cycle difference is always kept, so that cycle of suction and discharge is ensured.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples of implementing the disclosure, and that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure.
