Description

The invention relates to hydraulic engineering and can be used in devices with a pulsating fluid supply.

A hydropulse installation is known, comprising a housing with high and low pressure chambers connected to a power source and atmosphere and a distributor fl}

The disadvantage of this installation lies in the complexity of its design.

A hydropulse installation is also known, comprising a pump, an air cap installed in a pressure pipe. A pump, a connecting pipe and a water pulsator made in the form of a housing with a cavity connected to the pressure pipe, and a spring-loaded valve in the main trunk and the auxiliary barrel connected to the drain connecting pipe has nozzles with a shock valve and a clamp that is elongated with the possibility of longitudinal movement relative to the barrel D.2 J.

The disadvantage of such an installation. It is impossible to control the frequency of the pulsations.

The purpose of the invention is to provide control of the frequency of pulsations.

The goal is achieved by the fact that a hydropulsive installation containing a pump, a military cap installed in the pump discharge line, a connecting pipeline and a hydropulsator, made in the form of a housing with a flatness, and the main and auxiliary stems, moreover There is a spring-loaded valve installed in the valve, and the auxiliary barrel connected to the drain by the connecting pipe has nozzles with a shock valve and a lock made with the possibility of longitudinal The shaft is equipped with a switching device, made in the form of a two-way valve installed with the possibility of connecting the auxiliary shaft and cavity of the CT & borer of the pump discharge line and to the drain, and the auxiliary barrel is equipped with a fastening device, made in the clamp set.

Figure 1 shows a diagram of the pulse installation; figure 2 - hydro, pulsator, longitudinal section; on fig.Z - section aa in figure 2.

Hydropower installation contains a pump 1, an air cap 2 installed in a pressure line 3 of pump 1, a connecting pipe 4 and a hydropulsator 5 made in the form of a body 6 with a cavity 7 and the main and auxiliary barrels 8 and 9. In the main barrel 8, a valve 10 is installed, and the barrel 9 has nozzles 11 with a shock valve 12 and a latch 13. The switching device is made in the form of a two-way valve 3, 14 connecting the auxiliary barrel 9 through the pipe 15 and the cavity 7 of the pulsator 5 .1 to the trunk 3 and to the drain 16, and the mounting device the nozzle 11 is made in the form of a collet clamp 17.

The installation works in the following way.

To start the installation, install the UNIT. two-way valve .14 to position. . when pump 1 is connected to auxiliary trunk 9 through pipe 15, while the working fluid moves the impact valve 12 by the fwxator 13 to the side of the main barrel 8. Then, the two-way valve 14 is switched to the working position and the fluid enters the cavity 7 guide: | the pulsator 5 through the connecting pipe 4. When the working pressure is reached, in the hydro pulsator 5 the shock valve 12 depresses the retainer 13 and moves along the nozzle 11 by suddenly closing the channel of the auxiliary barrel 9. A hydraulic shock occurs, the action of which opens the valve 10 and the pressurized fluid enters the main barrel 8 of the throat pulsator 5. With the reverse of the water shock, as a result of the discharge, the shock valve 12 returns to the detector 13. When fluid flows to the auxiliary barrel 8, the cycle repeats.

The frequency of the pulsations depends on the distance from the impact valve 12 to the valve ID. Moving the nozzle 11 together with the shock valve of the auxiliary barrel 8 changes this distance, and consequently, often the pulsation. Having set the required frequency, the fixture llj will be secured with the help of the collet clamp I.

Performing a hydropulsator with a moving nozzle allows you to change the pulse frequency, which expands the field of application of the hydropultative pattern.
