Dynamic mechanism to lift the fluid to highest

Abstract

A dynamic fluid pump for illustrating fluid dynamics includes a basin of the fluid have a base and a mass of fluid from the basin surface to the base. The dynamic fluid pump is supported at the bottom of the basin. The dynamic fluid pump includes four inner pipes. Two from the inner pipes are upwardly to the fluid tank, one upwardly to the surface of the basin and one act as a vent. The Smallest inner pipe are inside the main inner pipe and the secondary inner pipe smaller diameter than the main inner pipe. Two upwardly inner pipes (main and secondary) each one includes a piston in the bottom of the basin connected together to a pivot assembly in the base of the basin. So that, one of the pistons is at or near the top of one of the inner pipes when the other of the pistons is at or near the bottom of the other inner pipe.

1 . A dynamic fluid pump mechanism, the mechanism comprising:
 a basin of liquid, the basin of liquid having a base and a mass of liquid within the basin and having a liquid surface;   a liquid tank located above the basin;   a dynamic fluid pump comprising:
 a main inner pipe extending upwardly from the base of the basin to the upper end of the basin; 
 secondary and smallest inner pipes extending upwardly from the basin to the liquid tank, the secondary and smallest inner pipes having a smaller diameter than the main inner pipe, the smallest inner pipe having a diameter smaller than the secondary inner pipe and at least a portion of the smallest inner pipe being located within the main inner pipe; 
 a vent inner pipe extending upwardly from the basin and open to atmosphere at an upper end thereof; 
 a first piston located in the main inner pipe; 
 a second piston located in the secondary inner pipe; and 
 a pivot assembly located at the base of the basin and connecting the first and second pistons such that the first and second pistons reciprocate in opposite directions within the respective main or second pipe so that one of the pistons will go down within one of the inner pipes when the other of the pistons will go up within the other inner pipe. 
   
     
     
         2 . A dynamic fluid pump mechanism according to  claim 1 , wherein, in use, the volume of liquid within the secondary inner pipe above the second piston is less than the volume of liquid within the main inner pipe above the first piston. 
     
     
         3 . A dynamic fluid pump mechanism according to  claim 1 , wherein, in use, the volume of liquid within the smallest inner pipe is less than the volume of liquid within the secondary inner pipe above the second piston. 
     
     
         4 . A dynamic fluid pump mechanism according to  claim 1 , wherein a main control valve is located within the main inner pipe at the upper end of the reach of the first piston. 
     
     
         5 . A dynamic fluid pump mechanism according to  claim 4 , wherein the secondary inner pipe further comprises a secondary control valve. 
     
     
         6 . A dynamic fluid pump mechanism according to  claim 4 , wherein the smallest inner pipe is located on top of the main control valve. 
     
     
         7 . A dynamic fluid pump mechanism according to  claim 6 , wherein the main control valve comprises an aperture located adjacent the bottom end of the smallest inner pipe and arranged to keep the smallest inner pipe open when the main pipe is closed. 
     
     
         8 . A dynamic fluid pump mechanism according to  claim 1 , wherein a damper is located within the smallest inner pipe, the damper being arranged to enable liquid flow therethrough upwardly towards the liquid tank but to prevent downward liquid flow therethrough. 
     
     
         9 . A dynamic fluid pump mechanism according to  claim 1 , wherein a damper is located within the secondary inner pipe, the damper being arranged to enable liquid flow therethrough upwardly towards the liquid tank but to prevent downward liquid flow therethrough. 
     
     
         10 . A method of operating a dynamic fluid pump according to  claim 5 , the method comprising the steps of:
 a) opening the main control valve and the secondary control valve;   b) filling the basin with liquid such that the secondary inner pipe fills with liquid and that the second piston moves down towards the bottom of the secondary inner pipe;   c) closing the secondary control valve;   d) filling the basin with liquid such that the liquid level reaches the top of the main inner pipe and fills said main inner pipe such that such that the mass of the liquid in the main inner pipe is larger than the mass of the liquid in the secondary inner pipe, causing the first piston to move down and the second piston to move up and push the liquid in the secondary inner pipe into the liquid tank;   e) opening the secondary control valve and closing the main control valve such that the mass of liquid above the first piston in the main inner pipe and in the smallest inner pipe is smaller than the mass of the liquid in the secondary inner pipe, causing the second piston to move downwardly and the first piston to move upwardly and force liquid to flow up to the liquid tank through the smallest inner pipe; and   f) closing the secondary control valve and opening the main control valve; and   g) repeating steps d) to f).
