Abstract
The utility model relates to the field of papermaking equipment, in particular to a controllable medium and high roller for hydraulic subareas, which aims to absorb vibration generated at pressure areas as much as possible, reduce influence to a roller surface rubber layer and operation of equipment due to vibration of the pressure areas, prolong the service life of the roller surface rubber layer and increase stability of the operation of the equipment. The controllable medium and high roller for hydraulic subareas mainly consists of a barrel body 1, a mandrel 2, pistons 3 supported on the mandrel, a supporting device 4, a sealing device 5, an energy accumulator 7 and the like, the barrel body 1 is sleeved on the mandrel 2, and the mandrel 2 is provide with the pistons 3 in certain amount. The controllable medium and high roller is characterized in that the energy accumulator 7 is mounted at the bottom of a piston hole on the mandrel 2. As the energy accumulator 7 is mounted in the piston hole on the mandrel 2 of the roller, the distance from the energy accumulator 7 to a vibrating pressure area is short, pressure area vibration elimination effect of the controllable medium and high roller for hydraulic subareas is increased greatly, impact of the pressure area vibration to the roller surface rubber layer, a roller body and a framework is reduced, the service life of the roller surface rubber layer is prolonged, and stability of the operation of the equipment is increased.
Description
Technical field
The utility model relates to the papermaking equipment field, is a kind of hydraulic pressure subregion crown controlled roll specifically.
Background technology
Hydraulic pressure subregion crown controlled roll is mainly used in the press section and the calender of paper machine, development along with paper technology, hydraulic pressure subregion crown controlled roll has become the nucleus equipment of modernized paper machine and calender, its mainly by cylindrical shell, mandrel, be supported on parts such as piston on the mandrel, bracing or strutting arrangement, sealing device and form, some hydraulic pressure subregion crown controlled roll also has transmission device.Cylindrical shell is supported on row's piston of mandrel by hydrostatic pressure, lower part of piston is connected the outer hydraulic system of roller, the upper and lower surface of piston is connected by pore, hydraulic oil by pore spills between piston face and cylinder inboard wall, between the upper and lower surface of piston, to obtain a kind of pressure balance and stable oil film, to bear the pressure between piston and the cylindrical shell, hydraulic pressure subregion crown controlled roll can be divided into a plurality of nips, and each nip can comprise one or more pistons.Adjust the charge oil pressure at different parts piston place, just can adjust the uniformity of thickness evenness on the paper web banner direction, dehydration or other machine hand index of planting.According to the needs of machine hand's skill, the roller surface of hydraulic pressure subregion crown controlled roll can also can be the lick roller face for the steel roll surface.
No matter the hydraulic pressure subregion crown controlled roll press section that is used for the paper machine still is used for calender, when roller form error or woollen blanket in uneven thickness are arranged, when page passes through from nip, the capital makes roller produce little vibration, part vibration passes to the frame at roller two ends by mandrel, most of vibration is absorbed by hydraulic system by the oil film between piston and the roller shell, some vibration can be absorbed by the glue-line on rubber faced roll tube surface, causes the fatigue of glue-line, causes the glue-line life-span to descend.In order to absorb the vibration that roll nip produces, accumulator generally all is housed, in the hydraulic system of hydraulic pressure subregion crown controlled roll with the stability that guarantees the operation of roller and hydraulic system, the service life that prolongs the roll surface glue-line.Accumulator in the hydraulic system of existing hydraulic pressure subregion crown controlled roll is general all to be installed in together with the Hydraulic Station of hydraulic system, communicate with nip in the hydraulic pressure subregion crown controlled roll by fluid pressure line then, accumulator is far away with the position distance that vibration produces.The accumulator of hydraulic system is near more apart from the vibration source distance, and accumulation of energy or shock attenuation result are just good more, otherwise just poor more.Because the accumulator of existing hydraulic pressure subregion crown controlled roll hydraulic system is far away apart from vibration source, nip elimination of vibration effect is subjected to very big influence, a large amount of vibrations is absorbed by the glue-line of roll surface or passes to the frame of roller by mandrel, cause the glue-line life-span descend, cause equipment vibration, influence operation stability of equipment.
Summary of the invention
In order to absorb the vibration of nip generation as far as possible, reduce the shadow-sound of nip vibration to roll surface glue-line and equipment operation, prolong service life, the increase operation stability of equipment of roll surface glue-line.The utility model provides a kind of hydraulic pressure subregion crown controlled roll, accumulator is housed on the roller mandrel of this hydraulic pressure subregion crown controlled roll is connected with the nip of roller.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model mainly by cylindrical shell, mandrel, be supported on parts such as piston on the mandrel, bracing or strutting arrangement, sealing device, accumulator and form.Barrel jacket is contained on the mandrel, the piston of some is housed on the mandrel, these pistons are formed a plurality of nips, each nip lower part of piston interconnects and is communicated with roller hydraulic system outward, the top of piston contacts with inner barrel, on the piston, lower surface is connected by pore, fittable slackening device and sealing device between the two ends of cylindrical shell and the mandrel, barrel outer surface can also can be the lick roller face for the steel roll surface, it is characterized in that: accumulator is equipped with in the bottom in mandrel upper piston hole, the structure of accumulator can be spring, piston type, gasbag-type also can be other version.
The beneficial effects of the utility model are, because accumulator of the present utility model is loaded in the roller mandrel upper piston hole, the vibrative nip of distance is nearer, can improve hydraulic pressure subregion crown controlled roll nip elimination of vibration effect greatly, reduce the impact of nip vibration, thereby can improve the life-span and the operation stability of equipment of roll surface glue-line roll surface glue-line and roll body and frame.

The specific embodiment
Specific embodiment 1 as depicted in figs. 1 and 2, mainly by cylindrical shell 1, mandrel 2, be supported on parts such as piston 3 on the mandrel 2, bracing or strutting arrangement 4, sealing device 5, frame 6, accumulator 7 and form.Cylindrical shell 1 is sleeved on the mandrel 2, and the piston 3 of some is housed on the mandrel 2, fittable slackening device 4 and sealing device 5 between the two ends of cylindrical shell 1 and the mandrel 2, and to guarantee that cylindrical shell 1 running is steady and avoid leakage of oil, cylindrical shell 1 outer surface is the kiss-coating roll surface.
In specific embodiment 1 and specific embodiment 2, accumulator 7 is the block rubbers with vibration damping, accumulation of energy effect, directly be positioned over the bottom of piston hole, this specific embodiment 1 and specific embodiment 2 are in use, because rubber has elasticity, the vibration part that the roll surface glue-line produces is absorbed by glue-line, and a part is delivered to hydraulic system by the roller shell, by 7 bufferings of the accumulator under the piston 3 and absorption.The accumulator 7 of specific embodiment 1 and specific embodiment 2 directly is loaded in the piston hole on the roller mandrel 2, compare the existing hydraulic pressure subregion crown controlled roll that accumulator is installed on the roll body outside, the vibrative roll surface nip of accumulator distance is nearer, can improve nip elimination of vibration effect greatly, reduce the impact of nip vibration, thereby can improve the life-span and the operation stability of equipment of roll surface glue-line roll surface glue-line and roll body and frame.
