Description

The utility model relates to the field of pump engineering, in particular to devices for lifting water, and can be used in hydrotransport systems for pumping liquids.

Known hydraulic ram containing a supply pipe with a shock valve installed in it, an air cap divided by an elastic diaphragm into a gas and liquid cavity, the liquid cavity of which is in communication with the supply pipe with a L-shaped pipe oriented in it along the flow towards the shock valve, and a gas cavity equipped with suction and discharge nozzles with check valves (SU 1317187, IPC F04F 7/02, publ. 06/15/1985).

In a known hydraulic ram, energy is transferred in the form of pressure to a gas stream for its further transportation, or use for performing work. The disadvantage of this device is the narrow range of use, since only gaseous products are used as the working medium.

A hydraulic ram is known that contains a working chamber with a shock West valve connected with pressure and air tanks, and the air tank is made in the form of caps evenly spaced around the circumference, equipped with discharge valves and connected to each other (SU 781403, IPC F04F 7/02, publ. 11/21/1980).

A disadvantage of the known device is the presence of unused potential opportunities to increase productivity, efficiency due to the fact that the fluid is supplied periodically.

Known hydraulic ram, including the supply pipe, housing, shock and supply valves, air cap, discharge pipe (BV Karasev, VI Dechev. Fundamentals of Hydraulics, hydraulic machines and agricultural water supply. "Harvest", Minsk, 1965, p . 155).

The disadvantage of this device is a small proportion of the rising water, especially at high elevation heights.

Known hydraulic ram containing a supply pipe with a shock valve and a fluid collector at the outlet, a diaphragm pump, the working density of which through check valves communicates with the fluid collector and a discharge pipe equipped with an air cap, an L-shaped pipe installed in the supply pipe and oriented along it flow towards the shock valve (SU 1742525, IPC F04F 7/02, publ. 06.23.1992).

The disadvantage of this device is the large size and the inability to use it to raise water from the well, the inability to remove excess gases generated in the pipe during operation of the ram.

The closest in technical essence to the claimed invention is a hydraulic ram containing a lifting stage, including a water supply (supply) pipe with a shock valve, a pressure (air) cap with an exhaust (discharge) and bypass valve, as well as a discharge (pressure) pipe connecting the cap with a water tank, a full damper made in the form of a rubber air chamber (RU 82798, IPC F04F 7/02, publ. 10.05.2009) is fixed to the upper part of the pressure cap with a fitting with a spool.

A disadvantage of the known device is the inability to raise water from a well with a diameter of more than 110 mm

The technical result consists in the possibility of raising water from a well with a diameter of more than 110 mm using a hydraulic ram pump without the use of electricity.

The technical result is achieved by the fact that the hydraulic ram pump includes a supply pipe with a shock valve installed on it, an air cap, a discharge valve and a pressure pipe. The feed pipe is U-shaped, and the end of the feed pipe with a shock valve is U-shaped. The discharge and additional valves are connected to the upper part of the supply pipe. The discharge valve is connected to the air cap, which is connected by means of a valve to the pressure pipe. An additional valve is connected to a valve for regulating the outlet with the possibility of discharge of gases from the supply pipe, and between the discharge and additional valves there is a supply valve with the possibility of pumping water into the supply pipe.

The drawing shows a view of a hydraulic ram pump.

The hydraulic ram pump includes a feed pipe 1. The feed pipe is made in a U-shape. The end of the supply pipe 1 is made in a U-shape with a shock valve 2 located on it. Pressure discharge 3 and an additional 4 valves are connected to the uppermost part of the supply pipe 1. The discharge valve 3 is connected to the air cap 5, which is connected via a valve 6 to the pressure pipe 7 (to the consumer). An additional valve 4 connected to the valve 8 serves to divert the gases generated in the pipe during operation of the hydraulic ram pump. On the supply pipe 1 between the discharge 3 and the additional 4 valves there is a supply valve 9 for pumping water into the supply pipe 1.

The operation of the hydraulic ram pump is as follows. The beginning of the supply pipe 1 is lowered into the deep well 10 below the water level of the soil well 11. The end of the supply pipe 1 and the shock valve 2 are lowered into the ground well 11 so that it is below the water level of the deep well 10, but above the water level in the ground well 11. Using a supply valve 9, water is poured into the supply pipe 1 until it is completely filled, then, with a few sharp up and down movements of the supply pipe 1 with a shock valve 2 located in the soil well 11, the operation of the hydraulic ram pump . Due to the movement of water through the supply pipe 1 by gravity from the deep hole 10 to the soil well 11, the force of movement of water moves the shock valve 2 to the annular stop, upon reaching the stop, the shock valve 2 instantly stops and a hydraulic shock occurs, accompanying the increase in pressure in the supply pipe 1 for the flow of water proceeding by inertia, while the discharge valve 3 opens and water flows into the air cap 5, from where it enters through the valve 6, which serves to regulate the pressure through the pressure pipe 7 to the consumer. Also during a water hammer, an additional valve 4 opens, located in the upper part of the supply pipe 1, through which the gases generated during the operation of the hydraulic ram pump are discharged. The valve 8 controls the opening of the gas exhaust opening from the supply pipe 1. After the pressure drops in the supply pipe 1, the shock valve 2 opens. The completion of the hydraulic ram pump is completed.

Compared with the known technical solution, the proposed utility model allows water to be lifted from a well with a diameter of more than 110 mm without using electricity due to operation of a hydraulic ram pump.
