RU39654U1 - PUMP INSTALLATION - Google Patents

Abstract

The pumping unit is used to lift water from wells, wells and open reservoirs using wind energy. When using the proposed technical solution (see Figure 1):

- the design of the installation is simplified, its mass is reduced and the manufacturing cost is reduced;

- operation of the installation becomes possible in places where there is no power line;

- consumes free wind energy;

- it is possible to change the working place of the pump by changing the length of the rope depending on the location of the water source. The shaft of the wind turbine 1 through a crank mechanism 2 is connected by a cable 3 to the pump plunger 6. A working spring 5 is installed between the plunger and the pump housing. When the cable moves with the plunger up, the suction valve 8 opens and the spring is compressed at the same time. The movement of the rope with the plunger down occurs due to the energy of the compressed spring, while the suction valve closes and the discharge valve 10 opens. To compensate for the compression force of the spring, the load 9 is suspended from the pump casing.

Description

Scope: for raising water from wells, wells and open reservoirs of small farms.

Known installations with a sucker rod pump, consisting of an electric drive, rocker-rocker, a column of steel rods and a plunger with a discharge valve, making a reciprocating movement in the cylinder with a suction valve at the end. A diagram of such an installation is depicted in the Great Soviet Encyclopedia, 1971, volume 6, p. 603.

The disadvantages of the known installations are:

- a large mass of rigid rods, which does not allow to make an easy installation using a low-power wind turbine;

- large metal consumption, material and monetary costs in its manufacture;

- its operation requires energy costs;

- the impossibility of changing the place of work of the pump without moving the installation.

The technical result of using the proposed technical solution:

- the design of the installation is simplified, the mass is reduced and the cost of its manufacture is reduced;

- the ability to operate the installation in areas where there is no power line;

- the possibility of changing the place of work of the pump by changing the length of the rope depending on the location of the water source.

The specified technical result is achieved when using a pumping unit, the diagram of which is shown in Fig. 1, where: 1 - a wind turbine, 2 - a crank mechanism, 3 - a steel rope, 4 - a nut, 5 - a spring, 6 - a plunger, 7 - a case pump, 8 - suction valve, 9 - load, 10 - discharge valve.

When the rope 3 with the plunger 6 moves upward, the suction valve 8 opens and the spring 5 is compressed at the same time. The rope with the plunger moves downward due to the energy of the compressed spring, while the suction valve closes and the discharge valve opens 10. The compression force of the spring depends on the depth from which water must be raised and less than the weight of the pump. Therefore, in order to increase the mass of the pump with an increase in the depth of the rise of water, a load 9 is suspended on the pump casing. The position of the pump in the water source located away from the wind turbine is shown in FIG. 2.

Example: A pump weighing 6 kg, driven by a 10 kg wind turbine with blades with a radius of 0.5 m, can pump 500 l of water per day from a depth of 20 m with a slight wind. The rope diameter of such an installation is 2.5 mm.
