Abstract
The utility model relates to the technical field of hydraulic system auxiliary device, in particular to a welded diaphragm accumulator. The prior accumulator usually adopts diaphragm type, piston type, spring type, and so on, and has the disadvantages of complex inner structure, small movement range of an isolator, highly difficult manufacture and high production cost. The welded diaphragm accumulator comprises an upper housing, a lower housing, an oil receiving head, an air plug, a fastening nut, a location ring, and a diaphragm, wherein the upper housing is connected with the lower housing by welding; an air inlet is formed at the center on the top of the upper housing; the air inlet is closed by riveting and welding the air plug; the oil receiving head at the center of the bottom of thelower housing is connected with a pressure system; and the diaphragm is fixed in the cavity formed by the upper cavity and the lower cavity through a location ring. the welded diaphragm accumulator has the advantages of simple structure, high application range, reduced size and weight, lowered production cost, and enhanced durability and reliability.
Description
Technical field
The utility model relates to hydraulic system auxiliary device technical field, specifically a kind of welding diaphragm accumulator.
Background technique
Accumulator is a kind of hydraulic pressure installation of stored energy, is applied in widely in the hydraulic system, makes system's pressurize, absorption pressure impact, pressure pulsation and stored energy, makes auxiliary power source compensatory pressure etc.Existing accumulator adopts diaphragm type, piston type, spring etc. more.Use the diaphragm accumulator of rubber material slider, have only and adopt the form that is threaded, difficulty of processing is big, the cost of production height, and seal relatively poor; And the accumulator of use wavy metal tubular construction slider, the sphere of activities of slider is less, and the internal structure complexity, and own wt is bigger, the cost of production height.
Summary of the invention
The purpose of this utility model provides a kind of welding diaphragm accumulator, and internal structure is simple, and small product size is less.
The technical solution of the utility model comprises upper shell, lower shell body, connects oily head; Also stifled by gas, locking nut, positioning ring, barrier film are formed; Upper shell links together by welding and lower shell body; Central authorities' welding of lower shell body bottom is equipped with and is connect oily head; The center of top of upper shell has suction port, and suction port is by stifled riveted joint of gas and welded closure, and the use locking nut is fastening, and locking nut and upper shell are by being welded to connect; Barrier film is fixed on by positioning ring in the cavity that is formed by upper shell and lower shell body, and barrier film is separated into atmospheric pressure cavity (also can be described as the gas end) and hydraulic pressure cavity (also can be described as the oil end) with cavity; Around diaphragm center several annular deformation band is arranged on the septum wall, the pressing of separator bottom central authorities has stopping-off piece.
The utility model upper shell and lower shell body, locking nut and gas are stifled all to adopt vacuum electron beam welding (DZW-6FB type vacuum electron beam welder is by the production of Beijing dimension hat Electronics Co., Ltd.) with upper shell, the welding that connects between oil head and the lower shell body; The high temperature (about the about 500-600 of workpiece surface temperature ℃) that has produced when having avoided conventional the welding is to the damage of barrier film; Materials (production of Bukema Energy Storage (Tianjin) Co., Ltd.) such as barrier film employing ECO or nitrile butadiene rubber are mixing have strengthened the sensitivity of barrier film action, have strengthened the working stroke of barrier film.
The utility model has the advantages that: the reliability and the serviceability that have improved accumulator, compare with the diaphragm accumulator of existing rubber material slider, strengthened the seal and the reliability of housing, reduced the difficulty of processing of housing, applied widely, increase the service life; Compare with the accumulator of wavy metal tubular construction slider, internal structure is simple, has reduced small product size and weight; Improve serviceability and reliability, saved the energy, reduced cost of production.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
Stifled, 2 locking nuts of 1 gas, 3 upper shells, 4 positioning rings, 5 lower shell bodys, 6 barrier films, 7 deformation band, 8 stopping-off pieces, 9 connect oily head among the figure.
Embodiment 1
As can be seen from Figure 1, the utility model comprises upper shell 3, lower shell body 5, connects oily 9; Also stifled 1 by gas, locking nut 2, positioning ring 4, barrier film 6 are formed; Upper shell 3 links together by welding and lower shell body 5; Central authorities' welding of lower shell body 5 bottoms is equipped with and is connect oily 9; The center of top of upper shell 3 has suction port, and suction port is by stifled 1 riveted joint and the welded closure of gas, and use locking nut 2 is fastening, and locking nut 2 and upper shell 3 are by being welded to connect; Barrier film 6 is fixed in the cavity that is formed by upper shell 3 and lower shell body 5 by positioning ring 4, and barrier film 6 is separated into atmospheric pressure cavity and hydraulic pressure cavity with cavity; Around barrier film 6 centers several annular deformation band 7 is arranged on barrier film 6 walls, can improve the sensitivity of barrier film 6, deformation band 7 intervals and width are 1.5-15mm, deformation band 7 bottoms are the arc that radius R is equal to or greater than 0.5mm, the effective thickness of barrier film 6 is equal to or greater than 2.5mm, and barrier film 6 bottom center pressings have stopping-off piece 8.
During work, enter in the hydraulic pressure cavity of accumulator through connecing oil 9, promote the gas in the barrier film 6 compression gas-pressure chambeies, the atmospheric pressure cavity volume is reduced, the compression shock of absorption pressure system and stored energy from the hydraulic oil of pressure system; Gas pressure in the atmospheric pressure cavity constantly increases, and when the gas pressure in the atmospheric pressure cavity during greater than the hydraulic pressure in the hydraulic pressure cavity, the gas in the atmospheric pressure cavity oppositely promotes barrier film 6, and compressing hydraulic oil is discharged accumulators from connecing oil 9, replenishes and improve the fluid pressure of hydraulic system.
