Problems solved by technology

Although it has a certain effect, it does not effectively slow down the failure, but it is very easy to cause damage and peeling of the bonding edge
In short, the aging, cracks, and failures caused by the high-frequency deflection of the rubber diaphragm have consistently plagued technicians in this industry.

Embodiment Construction

[0020] A bowl-shaped rubber diaphragm for an accumulator, referring to the accompanying drawings, includes a bowl mouth seal 1, a thickened bowl bottom, and an arc-shaped bowl wall 2 connected between the sealed bowl mouth and the thickened bowl bottom. The vertical section at the bottom of the thickened bowl is in the shape of a circular platform 3, and the side surfaces of the circular platform 3 and the inner surface of the arc-shaped bowl wall 2 are smoothly and evenly transitioned to form an arc surface. The bottom of the thickened bowl is inlaid with a special-shaped buffer chip 4 whose vertical section is an "inverted tray type". The buffer chip 4 is made of space aluminum, including a circular bottom support 4-2, a tray 4-1 and an annular groove 4-3 arranged between the two parts, a tray 4-1, an annular groove 4-3 and a bottom support 4-2 The junction with the rubber is arc-shaped. Six positioning buffer holes 4-2-1 are evenly distributed circularly along the peripher...

Abstract

The invention provides a bowl-shaped rubber diagram for an energy accumulator and belongs to the technical field of hydraulic accessories. The bowl-shaped rubber diagram structurally comprises a bowl mouth sealing part, a bowl bottom thickening part and an arc bowl wall connected between a sealed bowl mouth and a thickened bowl bottom. The key lies in that the vertical section of the bowl bottom thickening part is in a circular-truncated-cone shape; the side surface of a circular truncated cone and the inner surface of the arc bowl wall are in uniform smooth transition to form an arc surface; and a special-shaped buffering core piece with the vertical section being in an inverted tray shape is inset in the bottom of the thickened bowl bottom. According to the bowl-shaped rubber diagram for an energy accumulator, the inverted-tray-shaped special-shaped buffering core piece is inset in the thickened part of the bottom of the bowl-shaped rubber diagram, and by means of the buffering structure and the elastic modulus characteristic of the core piece, the impact resistance strength and the high-frequency deformation capacity of the rubber diagram are improved, and the service life of the rubber diagram is prolonged.

Description

technical field [0001] The invention belongs to the technical field of hydraulic accessories, and relates to diaphragm type accumulator accessories, in particular to a bowl-shaped rubber diaphragm with a buffer chip used in this type of accumulator. Background technique [0002] The accumulator is an indispensable functional component in modern hydraulic technology and a regulating device in the transmission of hydraulic energy. It is mainly used in the process of hydraulic pressure conversion, receiving and transmitting pulse information of pressure changes, relieving changes in pulsation amplitude and flow, and stabilizing the output power of equipment. Diaphragm accumulators use compressed gas to drive a diaphragm to complete energy regulation. When in use, first fill the accumulator with gas of rated pressure, when the system pressure exceeds the internal pressure of the accumulator, the oil compresses the gas, converting the pressure in the oil into gas internal energy...
