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 has the diaphragm type, the pistontype, the 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, a support ring, a diaphragm, and a liquid receiving head, wherein the diaphragm is fixed in the cavity formed by the upper housing and the lower housing through a location ring to divide the cavity into a pneumatic cavity and a hydraulic cavity; the upper housing is connected with the lower housing by welding; an air inlet is formed at thecenter on the top of the upper housing; a charging head is welded at the air inlet; a seal screw is assembled at the center of the charging head; and the liquid receiving head is welded at the centerof the bottom of the lower housing. The welded diaphragm accumulator has the advantages of simple structure, enhanced durability and reliability, high application range, reduced size and weight, lowered production cost, and repeated use.
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, manufacture difficulty is big, the cost of production height, and sealing is poor; And the diaphragm accumulator of use wavy metal tubular construction slider, the sphere of activities of slider reduces, 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, solves the complex structure that existing diaphragm accumulator exists, and volume is bigger, and cost of production is than problems such as height.
The technical solution of the utility model comprises upper shell, lower shell body, barrier film, support ring, connects the liquid head; Barrier film is fixed on by support ring in the cavity that is formed by upper shell and lower shell body, and cavity 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); The pressing of separator bottom central authorities has stiffening plate; Upper shell links together by welding and lower shell body; The center of top of upper shell has suction port, and suction port place welded and installed has pneumatic head, and pneumatic head central authorities are equipped with sealing screw, and the junction is pressed with hydraulic seal combination mat or red copper pad between sealing screw and the pneumatic head; The central welded and installed of lower shell body bottom connects the liquid head.
Vacuum electron beam welding (DZW-6FB type vacuum electron beam welder is by the production of Beijing dimension hat Electronics Co., Ltd.) is all adopted in upper shell of the present utility model and lower shell body, upper shell and pneumatic head and lower shell body and the welding that connects between oily, and 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 sensitivity and durability that barrier film moves.
The utility model has the advantages that: compare with the diaphragm accumulator that is threaded of existing rubber material slider, reduced difficulty of processing, strengthened the seal of housing, increase the service life, applied widely; Compare with the accumulator of wavy metal tubular construction slider, the utility model has reduced small product size and weight, reduced cost of production, internal structure is simple, effective the sphere of activities of barrier film is bigger, has improved serviceability and reliability, and can replenish the air pressure intracavity gas, accumulator is used repeatedly, saved the energy.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
1 upper shell, 2 lower shell bodys, 3 barrier films, 4 stiffening plates, 5 support rings, 6 pneumatic heads, 7 sealing screws, 8 hydraulic seal combination mat, 9 connect the liquid head among the figure.
Embodiment 1
As can be seen from Figure 1, the utility model comprises upper shell 1, lower shell body 2, barrier film 3, support ring 5, connects liquid head 9; Barrier film 3 is fixed in the cavity that is formed by upper shell 1 and lower shell body 2 by support ring 5, and cavity is separated into atmospheric pressure cavity and hydraulic pressure cavity; Barrier film 3 bottom center pressings have stiffening plate 4; Upper shell 1 links together by welding and lower shell body 2; The center of top of upper shell 1 has suction port, and suction port place welded and installed has pneumatic head 6, and pneumatic head 6 central authorities are equipped with sealing screw 7, and the junction is pressed with hydraulic seal combination mat 8 or red copper pad between sealing screw 7 and the pneumatic head 6; Central authorities' welding of lower shell body 2 bottoms is equipped with and is connect liquid head 9.
When underpressure occurring, can open sealing screw 7, replenish pressurized gass, accumulator be used repeatedly, energy saving by pneumatic head 6 when the air-loss in the accumulator atmospheric pressure cavity etc.
