Abstract
The utility model relates to an energy accumulator, in particular to a diaphragm type energy accumulator for a gather and delivery pump. The diaphragm type energy accumulator comprises an upper shell body, a lower shell body and a diaphragm. An inflation opening is formed in the top end of the upper shell body, and an oil outlet is formed in the lower end of the lower shell body. A rotating shaft is arranged on the inner wall of the lower shell body, a rubber plate rotating along with the rotating shaft is arranged on the rotating shaft, and a nut is arranged on the rubber plate. The rubber plate is connected with a diaphragm through the nut. The diaphragm type energy accumulator has the advantages that through the arrangement of the rotating shaft and the rubber plate rotating along with the rotating shaft, the service life of the diaphragm is prolonged, an anti-corrosion layer is arranged on the inner wall of the lower shell body, so that the service life of the lower shell body is prolonged, and through the arrangement of a pressure gauge, pressure changes in the energy accumulator can be visually observed, and the energy accumulator is more reasonable in structure, longer in service life, and more convenient to use.
Description
Technical field
The utility model relates to a kind of accumulator, is a kind of gathering and transportation pump diaphragm accumulator more specifically.
Background technique
Accumulator is stored energy commonly used in the hydraulic system; the equipment of steady pressure; accumulator constantly stores and discharges fluid in the work; therefore; pressure in the device chamber and volume are constantly changing; this variation is to finish by the distortion of diaphragm type rubber cup; because barrier film needs constantly to change, the frequency height, so the most common failure of diaphragm accumulator is that barrier film fractures; therefore need protect barrier film; secondly contain various impurity in the oil product, lower shell body is caused corrosion, reduced the working life of accumulator; and accumulator can't observe the working state of accumulator in the course of the work intuitively, can't identify whether proper functioning of accumulator fast.
In sum, now need a kind of long service life, the accumulator of being convenient to observe.
Summary of the invention
At above deficiency; the utility model provides a kind of gathering and transportation pump diaphragm accumulator; this accumulator has increased to the protection of barrier film with to the protection of lower shell body inwall; improved working life; add a pressure meter simultaneously and internal pressure is changed observed intuitively, be convenient to determine whether proper functioning of accumulator.
The utility model is achieved through the following technical solutions: a kind of gathering and transportation pump diaphragm accumulator, comprise upper shell, lower shell body and barrier film, the upper shell top is provided with inflation inlet, the lower shell body bottom is provided with oil outlet, the lower shell body inwall is provided with rotating shaft, rotating shaft is provided with the rubber plate that rotates with rotating shaft, and rubber plate is provided with nut, and rubber plate is connected by nut with described barrier film.
The increase of above-mentioned rubber plate has reduced the frequent turnover of barrier film self, has improved the life-span.
Above-mentioned rubber plate comprises rubber plate and following rubber plate, can be with diaphragm clip between last rubber plate and following rubber plate, and more firm.
The wide 1-3 of above-mentioned rubber plate centimetre.
Above-mentioned lower shell body inwall is provided with anticorrosive coat, and the lower shell body inwall is shielded.
Above-mentioned upper shell is provided with pressure meter, is convenient to observe the variation of accumulator internal pressure.
The position corresponding with oil outlet is provided with the backing shell on the above-mentioned barrier film.
The beneficial effects of the utility model are: by the rubber plate that rotating shaft is set and rotates with rotating shaft, improved the working life of barrier film, by at the lower shell body inwall anticorrosive coat being set, improved the working life of lower shell body, by pressure meter is set, can observe the accumulator pressure inside more intuitively and change, to sum up accumulator structure of the present utility model is more reasonable, longer service life, more convenient.
