High-pressure-resistant air bag capsule and preparation method thereof

Abstract

The invention discloses a high-pressure-resistant air bag capsule and a preparation method thereof.The high-pressure-resistant air bag capsule comprises a capsule body, a fixing bolt is fixedly embedded in the center of the inner side of the bottom face of the capsule body, a plurality of fan blades are rotationally connected to the outer side of the fixing bolt through bearings, and the interior of the capsule body is divided into an upper working cavity and a lower working cavity through the fan blades; when high-speed and high-frequency pressure fluctuation occurs, due to the existence of the high-speed and high-frequency pressure fluctuation, two working cavities are formed in the bag body, and when air in the bottom cavity moves into the top working cavity, the fan blades can be driven to rotate to play a damping role, so that the deformation speed of the bag body is gentle, and the deformation rate of the air bag is stabilized; the bottom of the air bag is prevented from bearing large impact force, the efficiency of each time of work can be ensured, and the whole bag body is balanced; the rubber cutting device is used for cutting rubber raw materials needed for preparing capsules, and the problem that rubber parts are prone to remaining on the rotating roller after rubber processing and cutting can be solved.

Description

technical field [0001] The invention belongs to the related technical field of air-encapsulated capsules, and in particular relates to a high-pressure-resistant air-encapsulated capsule and a preparation method thereof. Background technique [0002] The air bag is an important component for vibration reduction, buffering, pressure and flow stabilization in oil drilling mud pumps, and the air bag capsule is the core component of the air bag. The function of the air bag is to use its own volume to continuously store and compensate the discharge liquid of a part of the pump in the pipeline, so as to reduce the fluctuation of the pumped liquid. The air capsule is a thin-walled large rubber product. Its application environment determines that it must have good high temperature and high pressure resistance, oil resistance, aging resistance, corrosion resistance and other properties, as well as good mechanical properties. [0003] The application number is CN201410373059.5, which ...
