Embodiment 1

[0026] As a basic example:

[0027] The air pressure balance compensator used in the rolling air excitation negative pressure system includes an air pressure mechanism, and the air pressure mechanism is divided into a low air pressure chamber 1 and a high air pressure chamber 4. It is characterized in that the low air pressure chamber 1 and the high air pressure chamber 4 A balance compensator main body 2 is installed between them, and it is characterized in that a main body support 5 is installed in the center of the balance compensator main body 2, a balance compensator spring 6 is installed on the main body support 5, and a compensating spring 6 is installed on the balance compensator main body 2. The compensator buffer pad 8 and the compensator seal pad 9 are arranged symmetrically with the central axis of the balance compensator spring 6, the compensator seal pad 9 is connected with the upper sealing layer 3, and the compensator buffer The pad 8 is connected with a lower ...

Embodiment 2

[0030] This embodiment focuses on the improvements compared with the above-mentioned embodiments, and the similarities will not be repeated. In this embodiment, the upper sealing layer 3 and the lower sealing layer 7 are located on the same vertical plane, and the upper sealing layer 3 is provided with a There is an opening for the communication between the low-pressure chamber 1 and the high-pressure chamber 4, the compensator gasket 9 is flexibly connected to the upper sealing layer 3, one end of the lower sealing layer 7 is fixedly connected to the inner wall of the air pressure mechanism, and the lower sealing layer 7 The other end is hinged at the center of the main body support 5 .

[0031] The pressure of the low pressure chamber 1 and the high pressure chamber 4 in the present invention all act on the upper half of the main body support 5, when the pressure of the low pressure chamber 1 is less than the set value, the pressure of the high pressure chamber 4 pushes the m...

Abstract

The invention discloses an air pressure balance compensator used in a rolling type air excitation negative pressure system, belonging to the technical field of air pressure controllers and solving the problems of complicated structure and larger occupied space of the air pressure controller in the prior art. The air pressure balance compensator comprises an air pressure mechanism, wherein the air pressure mechanism is internally divided into a low air pressure cavity and a high air pressure cavity, a balance compensator main body is arranged between the low air pressure cavity and the high air pressure cavity, a main body support is arranged at the center of the balance compensator main body, a balance compensator spring is arranged on the main body support, a compensator cushion pad and a compensator sealing pad are also connected on the balance compensator main body, the compensator cushion pad and the compensator sealing pad are symmetrically arranged around the center of the center axis of the balance compensator spring, the compensator sealing pad is connected with an upper sealing layer, the compensator cushion pad is connected with a lower sealing layer, the upper sealing, the lower sealing layer and the balance compensator main body separate the interior of the air pressure mechanism to form a low air pressure cavity and a high air pressure cavity. The air pressure balance compensator adopts the lever principle, and has a simple and compact structure.

Description

technical field [0001] The invention belongs to the technical field of air pressure controllers, in particular to an air pressure balance compensator used in a rolling air-excited vibration negative pressure system. Background technique [0002] The exciter is a device attached to some machinery and equipment to generate excitation force, and is an important part of using mechanical vibration. The vibrator can make the excited object obtain a certain form and size of vibration, so as to perform vibration and strength tests on the object, or to calibrate vibration testing instruments and sensors. The vibrator can also be used as an exciting part to form a vibrating machine to realize the conveying, screening, compacting, forming and tamping of soil and gravel for materials or objects. According to the different excitation types, the vibrator is divided into inertial electric type, electromagnetic type, electro-hydraulic type, pneumatic type and hydraulic type. [0003] The ...
