Abstract
The utility model provides a double direction and pressure-increasing device. The utility model is suitable for the hydraulic circuit of the middle-high pressure and the high pressure. The utility model is composed of high pressure cylinder bodies symmetrically arranged on the two sides of a cylinder body of the pressure-increasing cylinder, and a big piston and a small piston which are connected in series. Four oil cavities are formed. The pressure-increasing oil cavities of the two sides are communicated with the high pressure oil cavities. Double direction movement is performed by the pressure-increasing piston, and high pressure oil is output by the high pressure cavity. The product is serialized, the utility model is adopted as required and is matched with hydraulic stations, the high pressure pump is replaced by the low pressure pump, the high power motor is replaced by the low power motor, and electric energy is saved. The utility model has the advantages of compact structure, convenient installation, and easy processing and manufacturing.
Description
The utility model relates to a kind of pressurizing cylinder, is applicable to the oil hydraulic circuit of mesohigh, high pressure and ultrahigh pressure.
Existing supercharging device generally is used for the ultrahigh pressure loop, carries out specialized designs and making on request, no standard series, and structure, supercharging mode, pressure source, commutation and the oil circuit of each device are all inconsistent, and the supercharging multiple is big, and special plane uses, and can not exchange.In mesohigh, high tension loop, working pressure is determined by the oil pump rated pressure, obtains through the running of motor drives oil pump, and the size of motor power (output) and the size of working pressure are direct proportional relations, cause bigger consumption of electric energy and loss.
Task of the present utility model: be that a kind of bidirectional booster oil cylinder and series product will be provided.Be used for mesohigh, high tension loop, adopt low pressure pump to replace high-pressure service pump, fractional electric motor to replace high power motor, reach the purpose of saving electric energy.
The utility model is to finish as follows: the bilateral symmetry of supercharging cylinder body is installed high pressure cylinder body, and the big corresponding series connection of small piston forms four oil pockets.Pressurized cylinder piston both sides oil pocket is communicated with the high-pressure cylinder oil pocket respectively, and equipped selector valve, one-way valve, pressure relay make its energy bidirectional-movement.Under pressurized cylinder piston to-and-fro motion pushing, the high-voltage oil cavity of both sides is constantly exported high pressure oil.The ratio of supercharging large tank and the little cylinder area alive of high pressure is its supercharging multiple.According to the specific requirement that hydraulic press uses, install relevant hydraulic element neatly additional and form required loop, obtain two kinds of pressure and flow, but fast feed repressurize, also directly supercharging.
Utilization the utility model adopts low pressure, medium pressure pump to replace the mesohigh pump, and middle pressure, mesohigh pump replace high-pressure service pump.Tested liquid cylinder pressure internal diameter size series (GB2348-80) is produced series product.Rated pressure, discharge capacity and required working pressure, flow by oil pump are selected for use.Replacement between gear pump and the vane pump, between the similar pump, cost has increase slightly, replaces plunger pump by gear pump, vane pump, can reduce cost significantly.Bidirectional booster cylinder structure compactness is installed on the table top or the side of volume hydraulic station more than 100 liters, and the integrated control of hydraulic element now can be installed additional with hydraulic station.The utility model is simple in structure, easily processing and fabricating.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the utility model.
Fig. 2 is a fundamental diagram of the present utility model.
With reference to Fig. 1, mainly form by high pressure cylinder body 1, supercharging cylinder body 2, piston 3, taper pin 4, piston rod 5, piston ring 6, floor clip 7, nut 8, seal ring 9.High pressure cylinder body 1, supercharging cylinder body 2 adopt integral type or combined type, the bilateral symmetry of supercharging cylinder body 2 is installed high pressure cylinder body 1, use bolton, corresponding symmetry is installed piston rod 5 in the both sides of piston 3, taper pin 4 rivet clasps, piston set ring 6 and seal ring adopt floor clip 7, nut 8 fastening, form supercharging, four oil pockets of high pressure.The outstanding round platform 8 of high pressure cylinder body 1 inner face processing, piston 3 is drilled in middle one aperture b radially, and the undersetting of supercharging cylinder body 2 has mounting hole c.In the fundamental diagram of Fig. 2, supercharging oil pocket A, the B of the utility model 10 are communicated with high-voltage oil cavity C, D respectively, and equipped one-way valve 11, pressure relay 12 and selector valve 13 are by 13 commutations of pressure relay 12 control selector valves, piston 3 bidirectional-movements, O, D chamber fluid produce high pressure output.
The utility model seriation is selected for use according to needs, and is supporting with hydraulic station, is mainly used in mesohigh, high tension loop, saves electric energy, also is applicable to the ultrahigh pressure loop, has good economic benefit and social benefit.
