Abstract
The utility model discloses an undamped static pressure cylinder device which is composed of a cylinder body, a plunger and an external cylinder body, wherein, the cylinder body is hermetically arranged in the external cylinder body; a gap is formed between the external wall of the cylinder body and the internal wall of the external cylinder body; the external cylinder body is provided with a fluid inlet which is communicated with the gap; the plunger is arranged in the cylinder body; a plurality of penetrated micropores are arranged on the wall of the cylinder body, thus the high-pressure and equivalent pressure fluid dielectric films generated by utilizing the micropores can be totally separated from the cylinder body by the fluid dielectric films; the damping does not exist; the plunger and the cylinder wall have zerofriction when the plunger moves upwards (or downwards).
Description
Technical field
The utility model relates to a kind of static pressure cylinder plug device.
Background technique
Piston places cylinder body at present, although adopt the piston ring or the inboard wall of cylinder block of low coefficient of friction material to inlay copper sheathing, this can only reduce friction, can not avoid friction and the loss generation.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of undamped static pressure cylinder-ram device, does not have friction between piston and cylinder body during this undamped static pressure cylinder-ram device work, and is lossless.
The utility model for the technical problem that solves its technical problem and adopt is: a kind of undamped static pressure cylinder-ram device, form by cylinder body, piston and outer cylinder body, the cylinder body sealing places outer cylinder body, form the gap between outer wall of cylinder block and the outer cylinder body inwall, outer cylinder body is provided with fluid input, described fluid input communicates with described gap, piston places cylinder body, the wall of cylinder body (comprising side and bottom) is provided with several and penetrates micropore, the isobaric flowing medium film of the high pressure that utilizes micropore to produce is like this intercepted piston and cylinder body fully by the flowing medium film, thus undamped.
The facade sidewall of cylinder body is provided with several and penetrates micropore, and some micropores are radial and axial uniform arrangement, and the aperture of micropore is smaller or equal to 2 millimeters.
Form the gap in cylinder body outer bottom and the outer cylinder body, the cylinder body bottom surface is provided with several and penetrates micropore at the end, and the aperture of micropore is smaller or equal to 2 millimeters.
The beneficial effects of the utility model are: this example utilizes flowing medium to form the end thrust of isobaric flowing medium film of high pressure and piston base to, radial equipartition micropore at Boring mill, reach equilibrium of forces with the suspended piston quality, the cylinder inner carrier is within the encirclement of flowing medium fully.Thereby make piston when making progress (or downwards) motion and between the casing wall, not have friction.
Description of drawings
Fig. 1 is a schematic representation of the present utility model.
Arrow shown in Fig. 1 is radial and axial thrust signal to piston.
Embodiment
Embodiment: a kind of undamped static pressure cylinder-ram device, form by cylinder body 2, piston 1 and outer cylinder body 3, cylinder body 2 sealings place outer cylinder body 3, form gap 5 between cylinder body 2 outer walls and outer cylinder body 3 inwalls, outer cylinder body 3 is provided with fluid input 31, described fluid input communicates with described gap, piston 1 places cylinder body 2, the wall of cylinder body 2 (comprising side and bottom) is provided with several and penetrates micropore 21, the aperture of micropore is smaller or equal to 2 millimeters, the isobaric flowing medium film of the high pressure that utilizes micropore to produce is like this intercepted piston 1 and cylinder body 2 fully by the flowing medium film, thus undamped.
The facade sidewall of cylinder body 2 is provided with several and penetrates micropore, and some micropores are radial and axial uniform arrangement.
