Also known from the description of the invention application No. 235654 a positive displacement piston pump with a manual drive, especially for drawing drinking water, which solves the problem of eliminating the phenomenon of water freezing in the pump at low ambient temperatures. The pump is composed of known elements: a column, a flow tube, a cylinder, a piston connected with a working arm by a rod. The cylinder with the piston is placed below the liquid table.

An adjustable drain valve located on the flow pipe and pump insulation allow the pump to be used also in winter. The pump allows you to draw water from a depth of 20 m, it is adapted to settling in dug and drilled wells. In order to reduce the working forces, an adjustable balancer is placed on the working arm of the pump, which balances the weight of the tie rod and the piston.

Principle of operation.

The gravity pump Fig. 2 has two parallel discharge manifolds 25. The purpose of this solution is to eliminate unnecessary energy consumption for the work needed to lift the liquid column in the discharge manifold 25 and reduce it to the amount needed to pump out the volume of liquid determined by the movement of the integrated pistons 6,22 and overcoming losses in the device.

^^ Workload in the gravity pump: (without taking into account losses)

P1 = F x s = mx dx s = Vtx ę x dx s F = mxg m = Vx ς s = h - for pumps in operation

Vi = Π / 4 x D x h where D - piston diameter, h - stroke of integrated pistons, g - gravitational acceleration, ς - liquid density.

Performance of other pumps: (without taking into account losses)

P2 = V2xe gxs

V2 Π / 4 x d2 x H where D - diameter of the pistons, H- height of the discharge manifold from the above mentioned results P2 / P1 = H / h

Such effects are obtained using the "connected vessels principle", which in a gravity pump form two parallel discharge manifolds 25 connected by a transformer 4, in which two integrated pistons 6, 22 move in accordance with the movement of liquid columns in the discharge manifolds 25. Weights of liquid columns in the discharge manifold the left and right cancel each other according to the above-mentioned principle throughout the entire pump operation, as a result of which we do not use energy to raise the liquid column, regardless of its height H.

Pump operation

Movement 1 - choke.

The pressure of the piston 15 causes the integral pistons 6 and 22 to move downward and the suction valve 20 to open, with the result that liquid is sucked into chamber 19.

Movement 2 - stamping.

The pressure of the piston 26 causes the integral pistons 6 and 22 to move upward and opens the discharge valve 16, and as a result the liquid is pumped out.

Movements 1 and 2 are described for a single-acting top drive pump. The principle of operation of the gravity pump also applies to two-sided pumps and bottom drive pumps.
