Technical field
The utility model is related to hydraulic pressure booster cylinder technical field, more particularly to one kind to devise general plug envelope, strong side seal, height
Press the hydraulic high-pressure pressurized cylinder of lattice Lay inside back cover seal structures.
Background technology
With the fast development of industry, the technology such as oil cylinder of the mould for matching and offer power is also constantly sent out
Exhibition, at present, known oil cylinder or cylinder are made up of cylinder body, piston, seal etc., form a kind of rigid dynamic sealing cavity, though
Larger pressure can so be born, but because piston back-and-forth movement causes sealing part abrasion to fail, easy oil cylinder oil leak and dangerous
Accident.Current industry high pressure is all sealed by copper, and its drawback is long-term work, and the abrasion of copper is larger.Generally work 10
Will carry out for ten thousand times with changing high-pressure sealing component, service life is not very long.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of high pressure for designing unique hermetical structure
Pressurized cylinder, is worked under 100MPA pressure with long-term use, through experiment test more than 3,000,000 times and excellent.
The technical scheme that the utility model is used is：A kind of hydraulic high-pressure pressurized cylinder, it is characterised in that：Including cylinder body,
Piston, high pressure chest body, enter oiled-plate method, the front and back end of cylinder body respectively with enter oiled-plate method and high pressure chest body is tightly connected, piston is located at
In cylinder body, piston is T-shape piston, and the upper end of T-shape piston constitutes a hydraulic fluid chamber with cylinder body, enters oiled-plate method and be provided with oil-feed to lead to
Road, connects hydraulic fluid chamber, and the lower end of T-shape piston is inserted into the intrinsic high pressure alveolus of high pressure chest；Under affiliated T-shape piston
Three road oil enveloping structures are provided with inside end and high pressure alveolus.
Three road oil enveloping structure includes being sealed as general plug envelope using special high pressure lattice Lay for first；Second uses high pressure
Circle and Teflon back-up ring are used as strong side seal；3rd road seals interior plus stainless steel coil using the customized general plug of German import.
Position and the high pressure of T-shape piston and high pressure chest body that the upper end of the T-shape piston contacts with inboard wall of cylinder block
The position of the preceding end in contact in alveolus is equipped with from profit fixed cover.
The beneficial effects of the utility model are：By the implementation of the technical program, piston rod is inserted into the work in high pressure cylinder area
Stopper rod is provided with three road oil enveloping structures, realizes being worked with long-term use under 100MPA pressure, through experiment test more than 3,000,000 times
Back and forth movement, it is and excellent, increase the service life of pressurizing cylinder, and solve existing pressurizing cylinder and use
Copper is sealed, and its drawback is long-term work, and the abrasion of copper is larger, it may appear that the phenomenon of oil leak, the design extends the use of oil cylinder
Life-span, and avoid the problem of oil leak permeability.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Specific embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
Refer to accompanying drawing 1, a kind of hydraulic high-pressure pressurized cylinder, it is characterised in that：Including cylinder body 2, piston 4, high pressure chest body
3rd, enter oiled-plate method 1, the front and back end of cylinder body 2 respectively with enter oiled-plate method 1 and high pressure chest body 3 is tightly connected, piston 4 is living in cylinder body 2
Plug 4 is T-shape piston, and upper end and the cylinder body 2 of T-shape piston constitute a hydraulic fluid chamber 10, enter oiled-plate method 1 and be provided with oil inlet passage 5, even
Logical hydraulic fluid chamber 10, the lower end of T-shape piston is inserted into the high pressure alveolus 11 in high pressure chest body 3；Under affiliated T-shape piston
Three road oil enveloping structures are provided with inside end and high pressure alveolus 11.
Three road oil enveloping structure includes being sealed as general plug envelope using special high pressure lattice Lay for first 7；Second 8 is using high
Trim ring and Teflon back-up ring are used as strong side seal；3rd road 9 seals interior plus stainless steel coil using the customized general plug of German import.
Position and the height of T-shape piston and high pressure chest body 3 that the upper end of the T-shape piston contacts with the inwall of cylinder body 2
The position of the preceding end in contact in alveolus 11 is pressed to be equipped with from profit fixed cover 6.
The high pressure pressurized cylinder simple structure designed by the technical program, durable can be under 100MPA pressure with length
Phase uses work, through experiment test more than 3,000,000 times and excellent.Its principle is：To push away small secondary booster greatly.Electricity
Machine drive gear pump carries out low-pressure charging（12MPA）, low pressure is converted into by oil circuit and magnetic valve by more than super-pressure 100MPA.
Its intermediate portions is high pressure sealing part, and current industry high pressure is all sealed by copper, and its drawback is long-term work, the abrasion of copper compared with
