Description

Shock absorber for electric vibration pump

The claimed invention relates to the field of domestic pump engineering and for vibrating pumps for lifting water from wells and wells.

Known analogues of vibration pumps Kid plant Dynamo, Moscow; The trickle of the plant Livhydromash, Mr. Livny, Oryol region; Aquarius of the plant named after Lepse, Mr. Kirov; Spring of the heavy engineering plant, Ivanovo and many others.

Pumps consist of two housings connected to each other by a rubber shock absorber, with the help of which the pump is secured and sealed. If the screws (or bolts) connecting the housings are not tightened properly, as well as due to the aging of the rubber during the operation of the product, the tightness of the connection between the housings and the shock absorber gradually occurs. As a result of this, water can penetrate the electromagnetic chamber, which will lead to a sharp decrease in work efficiency pump and even to a complete cessation of water supply, Penetration of water into the air chamber entails a violation of the electrical safety of the product.

Closest to the claimed is the rubber shock absorber of the household vibrating electric pump BV-0.12-40 Aquarius-1 g Kirov, which has a similar purpose and consists of a profile part made in the form of a body of revolution and a flange part made in the form of a sealing ring, where there is a through hole for supplying water to the discharge pipe and open holes in which are placed the screws (bolts) for attaching the hydraulic chamber to the housing} with electric drive

In the claimed invention, the reliability of the tight connection is ensured by improving the design of the shock absorber, namely

- along the perimeter of the shock absorber, from the side of the hydraulic chamber mounting, one or several profile section rollers are executed that exactly repeat the shape of the outer contour;

- A roller with a similar profile is also made around the conical part of the shock absorber, from the side of the hydrochamber, eliminating the possibility of water penetrating through the gaps in the vibrator into the electromagnetic chamber;

- along the perimeter of the shock absorber, from the side of the air chamber where the electric drive is located, a profile cross-section roller is repeated, repeating the shape of the outer contour;

- from the side of fastening of the air chamber of the electric drive around the hole for supplying water to the outlet pipe, a profile section roller is also made;

-all sealing rollers can have the same or different shape, height and cross-section.

The invention is confirmed by drawings (see Fig. 1, 2,3).

The pump consists (see Fig. 1) of two bodies, in one of which there is an air chamber 3 with an electromagnetic vibrator, in the other - a hydrochamber 2. The bodies are connected to each other through an elastic shock absorber 1, which provides fastening and sealing of the bodies. The shock absorber is rubber with metal fittings inside, has a profile part made in the form of a body of revolution, and flanged, made in the form of an o-ring. To supply water to the discharge pipe 5 of the pump, the shock absorber has a special hole 6. On the outside of the part, open holes are made in which there are screws or bolts 4 for fastening both cases. Moreover, the water intake can be performed either from the bottom of the pump, as shown in Fig. 1, or from the top, which is determined by the corresponding arrangement of the air chamber and the hydraulic chamber.

Figure 2 shows a shock absorber having a through hole 6 for supplying water to the pressure pipe of the housing and open holes 7 for attaching the hydraulic chamber to the motorized housing. Along the perimeter of the shock absorber from the side of the hydraulic chamber mounting there is a profile section roller 8, repeating the shape of the outer contour and a double row of rollers 9 of the same section having the same height. Around the conical part of the shock absorber there is a roller 10 of the same cross section and height.

In Fig. 3 along the perimeter of the shock absorber, on the side of the mounting of the electric drive casing there is a roll 11 of a profile section, repeating the shape of the outer contour. Around the through hole 6 for supplying water to the discharge pipe there is also a roller 12 of a similar section.

To clarify the invention, photographs are attached to the application materials. In the photographs shown: photo 1 - view of the shock absorber from the mounting side of the hydraulic chamber; photo 2 - view of the shock absorber from the mounting side of the air electromagnetic chamber.

The inventive shock absorber can be manufactured in series in the conditions of existing production using existing standard equipment. Currently, prototypes and industrial designs have been manufactured and tested.
