Definitions

  • the subject of this invention is a piston pump used to transfer liquid from lower to upper level, utilizing gravity for this purpose. It may be used to pump liquids, also in the peak load power station or to pump water in mines. For operation during natural disasters, it would be easy to install in any difficult to reach area, and it may be also used indoor, e.g. in shelters.
  • hydraulic rams To pump water to higher level thee devices called hydraulic rams are used, which houses check valves, and the energy of flowing down water rises pressure in the tank, and this pressure pumps water onto the higher level.
  • PL 171953 describes the piston pump that contains a control system, which houses, in two holes, the suction valves and the outlet valves, while at their one end they are connected through a duct with the space above the piston, and the suction hole is located between the suction valves and the outlet is between the outlet valves.
  • NL7806787 describes the piston pump whose piston rod has a spherical end that rests on the plastic element. Such construction is to prevent tilting of the piston in the cylinder, that may cause the risk of leakage.
  • TW200612036 publication describes the water pump which is equipped with the pump cylinder, water tank, pressurized tank and the pressing cylinder, looking from the machine top downward.
  • the pump cylinder is provided with a pipe
  • the pressing cylinder has a pipe to discharge water
  • the two pipes have check valves
  • the pump piston is placed in the pump cylinder and it is located in its lower part through a connecting rod attached to the upper part of the pressurized tank.
  • the pressurized tank is equipped with the set of the floating bottom tank, and the first, second and third valve are provided for the pump piston, water tank and the pressurized tank bottom in order to control water discharge time.
  • the locking mechanism and the sensor are installed at the machine center to control the pressurized tank falling time. According to this invention the function of continued water pumping and discharge, or water lifting, is effected by the use of the pumped water gravity, so that the components operate cyclically and continuously.
  • a piston pump used to lift liquids to a higher level that includes the a cylinder connected to an outlet pipe through a check valve, is characterized with a piston being a disc and a piston ring, which during the piston downward stroke create together a tight connection.
  • the piston ring has a circular flange attached to it in the form of a stub pipe, on which an elastic gasket is seated and on which a pressure ring is located, on which the springy gasket is assembled with a thrust ring on it, that is combined with a piston cylinder, while the piston ring is equipped with brackets with forks, on which levers are mounted pivotally, articulated with thrust ring and by means of a joint with swivel-mounted arms with a ring which is rotationally mounted on a threaded rod, with a nut, which is rotationally bonded to the piston disc, while the piston ring has diagonal supports combined with a nut screwed on the threaded rod.
  • the cross coupler has a nut and
  • the threaded rod has a square tip, which through a cap is combined with a motor spindle.
  • levers elements are joined with Roman screws. Such construction facilitates adaptation of the gasket pressure force to the pump cylinder walls.
  • displacement elements are installed, especially in the form of air chambers.
  • These displacement elements may be made of Styrodur.
  • the displacement elements may be fastened to the piston cylinder external walls. The displacement elements facilitate emerging of the piston from the liquid introduced to the pump cylinder.
  • At least one of disc surfaces that contact the piston ring is covered with rubber.
  • the pump design has a simple construction and an essential advantage of such a solution is lack of any emissions to the environments during its operation.
  • Fig. 1 presents the pump block diagram
  • Fig. 2 schematic diagram of the piston sealing in the pump cylinder
  • Fig. 3 connection of the piston cylinder damper with the spiral springs of drums mounted on the pump cylinder edge
  • Fig. 4 the pump operational diagram in upper position of the piston
  • Fig. 5 the pump operational diagram in lower position of the piston
  • Fig. 6 A-A top view of the beam with guides and slides of the piston ring
  • Fig. 8 - W-W view with Fig. 1 of the cross link mounted on the piston ring slides.
  • the cylinder bottom 1 is connected to the outflow pipe 2, on which, in the lowest position, an automatic check valve 3 is installed.
  • the pump piston 4 is composed of a disc 11 and a ring 13, that during the piston downward movement create a tight joint together.
  • an air chamber 12 is fastened to a piston ring 13, in its shape, that is the piston's displacement element.
  • a circular flange 14 is attached to the piston ring 13, creating together with the walls of the cylinder 1 a space to accommodate a springy gasket 15.
  • a thrust ring 16 is located, with which a piston cylinder 5 is combined being a tank of the piston 4.
  • the piston ring 13 is equipped with supports 24 with forks, on which levers 20 are mounted pivotally, connected jointly with a clamp ring 16, and through a joint 17 with arms 19 pivotally combined with a ring 21, which is pivotally mounted on the a threaded rod 25.
  • Location of the ring 21 on the rod 25 is set by a first nut 18.
  • the rod 25 is combined, through a taper bearing with a cap, with the piston disc 11.
  • the piston ring 13 has also slanting supports 22 combined with a second nut 23, which is screwed on the rod 25.
  • Location of the other end of the rod 25 is stabilized with a third nut 26 of a cross link 27 mounted on slides 32 of the piston 4 ring 13.
  • the threaded rod 25 has a square tip, which through a cap is combined with an electric motor M flexible spindle 8 that periodically drives the rod 25.
  • an electric motor M flexible spindle 8 that periodically drives the rod 25.
  • dampers 6 that are connected by strands 30 with drum spiral springs 31, mounted on the pump cylinder 1 edge.
  • bumpers 33 are mounted, that closes the dampers 6 of the cylinder 5 in the upper position of the piston 4.
  • brackets 28 a beam 7 is installed with lateral arms, to which pipe guides 29 are fastened, inside which there are slides 32 that lead to the piston 4, attached to the piston 4 ring 13.
  • the slides 32 placed in the pipe guides 29 allow for stable positioning of the piston 4 in the cylinder 1.
  • liquid from the lower tank 9 fills the cylinder 1, and then by rotation of the threaded rod 25, the disc 11 with the piston 4 ring 13 is closed, and at the same time the levers 19 and 20 press the springy gasket 15, that fills the space between the flange 14 and the cylinder 1.
  • the piston 4 cylinder 5 dampers 6 are closed.
  • the piston 4 is sealed, the piston 4 cylinder 5 is filled with the liquid amount equal to the liquid volume displaced by the piston 4 from the pump cylinder 1 during the work stroke.
  • Weight of liquid in the cylinder 5 increases pressure in the pump cylinder 1 and the check valve opens in the outflow pipe 2, where the liquid is raised with the weight that balances the pressure caused in the cylinder 1.
  • the liquid from the cylinder 1 is displaced into the upper tank 10.
  • Liquid raised to the certain level has a potential energy that may be easily transformed into another type of energy, for example, into electrical energy.
  • the essential advantage of this solution is lack of emissions during operations, no pollutions to the environment, and the use of gravity force is beneficial both in terms of environmental and natural resources protection, as well as significant energy saving.
