The invention, from pumping to construction, relates to volumetric diaphragm pumps, and can be used in various sectors of the national economy for pumping various fluids.

The purpose of the invention is to increase the reliability of the vibrodrive of the volumetric pump diaphragm.

The drawing shows the pump with the proposed vibropry diaphragm

Vibropractor diaphragm of a volumetric pump contains a cylindrical hearth 1 with a channel 2 for supplying the drive medium at its end 3, about 4 nat hectares on the side surface 5 adjacent to the end 3, and discharge channels 6. The core 1 is covered with tension by an elastic stocking diaphragm 7. On the surface of the end 3 of core 1, the following is made: notch 8, communicated with channel 2 to supply the driving medium, and on the lateral surface 5 behind 4 x 4 hectares - ring groove 9, connected to channels 6 of the drive medium removal, and the vibro-drive is additionally supplied with a spring-loaded spring 10 cup 11, pressed against the diaphragm 7 from the end face 3 of the core 1 Core 1 is installed in the pump housing 12, and the diaphragm 7 is fixed on it with a ring 13. The pump is equipped with a suction nagneta- Tel'nykh klapanag m-w 14 and 15, respectively, mounted -to pump chamber 16, supply channel 2 is provided with a throttle actuating medium insert 17.

When the drive medium is supplied under pressure through channel 2, it enters the recess B and, when the pressure reaches a predetermined level corresponding to the spring force 10, related to the recess area 8, the diaphragm 7, overcoming the spring force 10, is pressed from the end 3 of the core 1. an increase in the area of the diaphragm 7, which is influenced by the pressure of the driving medium, which further contributes to the release of the diaphragm 7 from the core 1. Expanding, the diaphragm 7 moves away from the bottom 4 tension and opens free access to the annular groove 9 for the drive Second environment, Pos

the ice is quickly released from the cavity of the diaphragm 7 into the groove 9 and further into the discharge channels 6. (This fragment of the cycle is shown on the right half of the drawing).

When the drive medium is etched off, the pressure in the cavity of the diaphragm 7 drops sharply and under the action of the cup 11 and the spring 10, it sits on the end 3 of the core 1. Then the cycle repeats.

When the diaphragm 7 oscillates, a periodic change in the volume of the pumping chamber 16 occurs, the pumped medium is sucked into it through the suction valve 14, and this medium is pumped to the consumer through the injection clan n 15.

Making the undercut 8 at the end 3 and the annular groove 9 on the lateral surface 5 of the core 1 contributes to achieving a clearer threshold for the vibration actuator to respond to pressure and to quickly release the pressure of the driving medium, which ensures a clearer and more reliable operation of the vibrodrive. At the same time, the throttle insert 17 also contributes to this by setting a more gradual increase in pressure compared with the speed of its discharge.
