Description

113071

The invention relates to a pulsating technique, in particular to a hydraulic pulsator, and is an improvement of the invention according to the author. St. No. 914827. 5

The purpose of the invention is to increase reliability by providing a constant load on the shaft of the blade wheel 9 and the drive shaft of the engine. fO

Figure 1 shows the device, General view, section; figure 2 - section aa in figure 1.

J5

The device comprises a housing 1, suction heads and discharge nozzles 2 and 3, an impeller A having blades 7 located between the disks 5 and 6 and a perforated shell 8 20 with a slot 9. The impeller 4 is provided with a spiral guide plate 10 adjoining the ends respectively to the edge 11 of the slot 9 and to the blade 7 made of slot 9 extended to the edge 12. The groove 13 is separated from the discharge nozzle 3 by radial 1 ebrahm 14 and connected to the suction nozzle 2 by channels 15 with an adjustable choke 16. The total cross-sectional area is the channel 15 with completely open throttles 16 must be such that the hydraulic resistance to the flow of fluid from the groove 13 into the suction patr-35 side is equal to the resistance to its outflow from the discharge port.

2

The device works as follows.

When the impeller 4 rotates, the fluid, interacting with the blades 7, receives a rotational-translational motion to the peripheral part of the wheel 4 and the slot 9. in the shell 8, When the slot 9 in the shell 8 coincides with the discharge pipe 3, the liquid is thrown out through it in a portion . At all other times, the liquid through the bore 13 and the channels 15 returns to the suction pipe 2. At the same time, by adjusting the throttles 16, the hydraulic resistance of the liquid from the bore 13 to the suction pipe 2 and its outflow from the pipe 3 is equal, including the resistance of the pipeline connected to the pulse or other system.
