The invention is intended to create hydraulic strikes and can be used in pump engineering, mechanical engineering and other areas of technology for crushing chips during deep drilling.

There are various designs of hydraulic rams. The generation of hydraulic shocks in such ramming is carried out with a shock valve.

The drawbacks of such a system for generating hydraulic shocks are the relatively low frequency of generating water hammer due to the reciprocating or oscillating movement of the shock valve; rapid wear of the valve assembly due to shock loads; practical failure of the system; if there is a high or high fluid pressure in the pipeline.

A device for producing hydraulic shocks in a flowing fluid is known, comprising a housing with inlet and outlet channels, a rotating rotor with alternating slots and protrusions.

The disadvantage of this device is that it is necessary in the engine to impede the rotor, and the resulting hydraulic shock is annular, and its total vector is zero.

The purpose of the invention is to reduce power consumption by allowing the rotor to rotate with flowing fluid.

This goal is achieved by the fact that, in a device for creating hydraulic shocks in a flow liquid, comprising a housing with inlet and outlet channels, a rotating rotor with alternating flanges

protrusions, the channels are made tangential, and the grooves are deaf.

The drawing shows the device, the overall appearance.

A device for creating hydraulic shocks in a flow-through fluid comprises a housing 1 with inlet 2 and outlet 3 channels, a rotating rotor 4 with alternating xaggi 5 and protrusions 6, the channels 2 and 3 being tangential and the grooves 5 deaf. The feed channel 2 is connected to lines 7 and 8,

The device works as follows.

Through the pipeline 7, the liquid enters simultaneously into the pipeline 8 and through the tangential supply channel 2 to the rotor 4, which comes into rotation under the pressure of the liquid. The fluid fills the groove of the rotor 4 and during the subsequent rotation of the rotor 4 is discharged through the discharge channel 3. repeats.

The application of the proposed device differs from the impact valve used in hydraulic packagings, the possibility of obtaining high frequency water hammer; reliability of operation due to the absence of sealing devices to block the outflow of fluid; the ability to work on a pipeline with a higher ti high liquid pressure,

The use of the device provides for deep drilling due to the generation of hydraulic shocks in the cutting zone, stable production of well transported crushed chips.
