AT518014A1 - Manual reciprocating pump with triple tube connection - Google Patents

Abstract

The main task of the proposed manual water pump is to provide water from the public water pipe network without electricity at low water pressure to any higher floor apartment. The proposal design includes a triple pipe connection {7), which is installed on a water pipe with two check valves {1, 6) {suction at the bottom and discharge at the top). Another type of valve (ball or gate) is installed between the horizontal branch of the triple pipe connection {7) and the outlet of the manual water pump. The design of this design is to take into account the required water volume and other design parameters to make changes to any reciprocating pump or through a new design of the manual pump. At the time when the water pressure is low and the higher floors are not reached automatically, the ball valve {8) should open and the pump should be operated manually or mechanically to suck and squeeze water into the water tank or for general use. On the other hand, in a natural situation with high water pressure, the ball valve {8) should be closed to disconnect the manual water pump because the water normally and naturally enters the tank or for use.

Description

Manual reciprocating pump with triple tube connection Previous technical situation:

Reciprocating pumps generally consist of a piston, which often moves inside the cylinder, which contains two opposite holes at the end of the pump, including two check valves. The first hole is, as shown in Fig. 1, connected to the absorption tube, while the other hole is connected to the pump tube

As the piston moves - retracts into the cylinder, low pressure will occur which leads to an open absorption valve, thus filling the liquid absorption into the inner cylinder pump. When the piston moves in the opposite direction, the absorption valve is closed, which leads to an increasing liquid pressure inside the cylinder and opens the pump valve to release the liquid from the pump tube.

The volume flow which is pumped by the pump is not fixed / fixed, it depends on the velocity of the piston and the volume of liquid inside the pump cylinder (cylinder volume = cylinder cross-sectional area x length of the piston stroke).

Detailed description of the proposed case:

The main purpose of the proposed pump is to extract water from the public network to provide upper floor apartments when the electrical energy is turned off and when there is not enough water pressure in the network to reach high floor apartments. Where water is available in the public network and only reaches ground floor apartments. Even though electricity is present, all the electric pumps will act together for all the houses, but none will receive water due to the low volume flow, especially the upper floors. Here it is possible to obtain the required water by hand or by a mechanical pump.

The proposed here reciprocating pump is somewhat similar to conventional piston pumps, except the design of the trailer and it is connected to the water pipeline. This design consists of the inside of the cylinder moving piston, which has a single-slot water pipe at its end. The slot is connected to a triple pipe connection and has a T-shape and has a manual control valve (can be of any type but the best is a ball valve to open and close quickly). The two other ends of the connection are connected to the pipeline using check valves, with the check valves installed on the drain line portion of the vertical pipe, as described in FIG. The lower branch of the triple-pipe connection is connected to the suction part of the pipe and the upper connection of the triple-pipe connection is connected to the drain pipe.

When the piston moves retractably in the cylinder, vacuum pressure occurs in the interior thereof and the suction valve is opened. Water passes from the intake pipe into the cylinder pump. When the piston movement for discharging / draining is back, the suction valve is closed and the pressure inside the cylinder pump is increased, and when the drain valve is opened, water comes to the tank or for general use.

The piston can be manually moved by an arm at low volume flow, where it requires low forces, while it can be mechanically operated continuously for a largest and highest amount of water.

The volume of pumped water = internal cylinder area cross section x stroke length of the piston

Example: If the diameter of the cylinder is 3 inches and the stroke length of the

Piston is 40 centimeters, we get a water volume of approximately (1.76) liters. * Dimension values can be changed with respect to the required parameter sizes. * A mechanical transmission mechanism could be used to move the piston at high water flow.
