RU1795159C - Pressure pulse exciter - Google Patents

Description

is aggressive, electrically or magnetically conductive (e.g., salt water). When heated during operation, the actuator interacts with the medium and is susceptible to corrosion and electromagnetic interference. These circumstances reduce the reliability of the pathogen, limit the scope of its use only for certain environments, lead to the need for special execution of actuators. The latter circumstance leads to the impossibility of using actuating elements manufactured by the industry, leads to their significant rise in price, and to an increase in weight and dimensions. Special / protective equipment leads to additional overheating of the actuating elements and to the need to increase the gaps between the actuating element and its working body, which leads to a decrease in efficiency. In addition, the location of the actuating element inside the acoustic container leads to great difficulty in its installation, dismantling and repair.

The purpose of the invention is to expand the scope and operational capabilities, increase efficiency and reliability.

This goal is achieved in that the pressure pulsation exciter is provided with two elastic pipes located in the second cavity of the acoustic container, one ends of which are attached to the lateral surfaces of the acoustic container, a central hard disk, to which the second ends of the elastic pipes are connected, an adapter connected to the working body the actuating element and the end surfaces of the central hard disk located inside the elastic pipes, the cylindrical part of which is located It is flexible pipes, associated with a partition, and in the side surfaces of the speaker capacitance is provided with two openings through which the adapter.

The main elements that make it possible to achieve this goal are elastic tubes that separate the excitable medium from the medium in which the actuator is located.

The use of flexible nozzles allows expanding the scope of application of the pressure pulsation pathogen in various (including aggressive) environments, since elastic nozzles can be made of a material that is not destructible

aggressive environments, or they can be easily isolated from aggressive environments. The location of the actuating element outside the excited medium makes it possible to freely access it, which is convenient in operation, does not lead to its overheating, and allows the use of standard actuating elements.

The drawing shows a functional structural diagram of a pressure pulsation exciter.

The pressure pulsation causative agent comprises an acoustic container 1 with cavities 2 and 3, an elastic partition 4, throttle holes 5, a sheath 6, a central hard disk 7, elastic pipes 8 and 9, an adapter 10, an actuator 11 with a working body 12, a drive 13, the rod 14, the excited medium 15,

The acoustic container mounted on the shell 6 is divided by an elastic partition 4 and throttle holes 5 into two cavities 2 and 3. The cavity 3 is in communication with the excited medium 15. In the cavity 2 there are elastic pipes 8 and 9, one ends of which are attached to the side surfaces of the acoustic container 1, and others to the central hard drive 7. The adapter 10 is connected to the working body

12 of the actuating element 11 and a part of the central hard disk 7 located inside the elastic pipes 8 and 9. Another part of the central hard disk 7 located outside the elastic pipes is connected to the partition 4 by means of the rod 14. The actuating element 10 is connected to the drive 13.

The device operates as follows. The signals transmitted from the drive 13,

the working member 12 of the actuator 11 is driven to vibrate, which drives the elastic partition 4 through the adapter 10, the central hard disk 7 and the shaft 14.

The vibrations of the septum are transmitted to the working medium 15 through the cavity 3.

As the partition 4 can be used, for example / membrane elastic or piston. As elastic

nipples 8 and 9 can be used, for example, bellows or interconnected alternating rigid and elastic rings.

Thus, the presence of elastic

the nozzles allows the actuator to be located outside the excited medium, which increases operational capabilities, increases the efficiency and reliability of the device.
