Description

The subject of the invention is a hydraulic ram intended for lifting water from rivers and made in the form of a straight pipe, which is equipped with shock and discharge valves.

Known devices of this kind were not widely spread, since the design does not allow them to be used on rabbi rivers with a honey flow.

In the present invention, this difficulty is solved by increasing the velocity of the water flow in the pipe. For this purpose, the ram at the inlet of the pipe is equipped with a system of conical concentric nozzles, and at the exit of its mouth, with a Venturi-type nozzle.

FIG. 1 shows a hydraulic ram in longitudinal section; in fig. 2-but the direction of flow.

The hydraulic ram is made in the form of a straight pipe / and is equipped with a shock 2 and pressure 3 valves.

At the inlet of pipe 1, the ram has a series of concentric nozzles 4 that serve to increase

water velocity in the pipe / and at the outlet of the mouth of the 5 nozzle 6, made in the form of a pipe Vepturi and pre) 1 designated for the same purpose.

A pressure pipe is used to drain water from the ram into the tank 7.

The operation of the device is as follows.

The whole device is immersed in a stream of water at a distance of depth and zakrenl.chets in such a position so that the conical nozzles - / were covered with their sockets against the flow.

The conical nozzles 4 force down the water flow jets and sequentially direct them from large tailings in mennen, from which the flow enters the straight feed pipe /, thus obtaining a significant speed. At the exit of the pipe, a pipe / note of water enters the nozzle 6, where the streams of water flow are picked up by the jets of the accelerated flow, which forms behind the mouth of the pipe / sparse protrapet. Having obtained here a sufficient speed to complete the movement of the shock clad of 2, the hands of the stream pick it up; moving, the clathtap will quickly close the opening of the exit of the 5ode from the mouth of the pipe and move along the pit in the pitta; In a pipe, a column of water will strike, thus, in a hydraulic system, a hydraulic impact occurs in the pipe.

The flow rate is measured in pressure; the flow of water from the ikercin tubular pipe and under pressure, which is received from a hydraulic shock, rushes into the main pipe 8, flows into the i-ia of its way and the pressure valve. on the rise.

The backwater shock of clan and clan 2 opens. After this, the pressure levels off, the beginning of a new period of increasing speed comes and the nrodees automatically recurs: a new hydraulic shock is obtained and a new portion of water is added to the reservoir 7.

The proposed construction of a ram will increase the efficiency of such a water-lifting device and will make it possible to use it on rivers with a relatively slow flow of IHiCM.

Subject N o d e b e

A hydraulic ram for raising water from rivers, performed in the form of a straight pipe, fitted with percussion and discharge valves, has a tag that, in order to improve its efficiency by increasing the velocity of the water, it flows in the pipe of the ram, it is provided at the entrance of the pipe with a system of conical concentric nozzles, and at the exit of its pipe with a mouth of a Venturn type nozzle.
