Abstract
The utility model provides a fixed guide wheel device used for a dry gas chamber to constrain motion deviation of a piston, belonging to the technical field of gas storage. The fixed guide wheel device comprises a rotating wheel, a baffle plate, a bolt, a washer, an oil cup, a screw, a shaft sleeve, a rotating shaft, a left supporting frame and a right supporting frame, wherein the rotating shaft penetrates into the internal diameter of the shaft sleeve and is connected with the shaft sleeve by the screw; two ends of the rotating shaft are embedded in the baffle plate; and the left baffle plate and the right baffle plate are fixed on the left supporting frame and the right supporting frame respectively by the bolt and the washer. The fixed guide wheel device has the advantages that the reliability of the fixed guide wheel is effectively improved, the abrasion of parts is reduced, and the service life is prolonged.
Description
Technical field
The utility model belongs to coal gas storing technology field, particularly a kind of stator ring device that is used for dry gas holder confined piston movement warp.
Background technique
Iron And Steel Plant are rich anies influential family of energy consumption in the national economy, therefore Iron And Steel Plant energy-saving and cost-reducing has vast technology space, blast furnace gas, coke-stove gas is Iron And Steel Plant's ironmaking, the by-product gas of steel-making product, be good secondary energy, should reclaim and utilize, blast furnace gas, coke-stove gas is the by-product gas of companion's explained hereafter, it reclaims with utilization must follow the storing technology rule that main body satisfies technological requirement, setting up the coal gas storage facility is gas cabinet, gas cabinet has two kinds of patterns by the principle classification of sealing gas: dry type and wet type, dry gas holder has storage technology parameter excellence, rational in infrastructure, Technological Economy advanced person's technology characteristics, be subjected to promoting the use of widely, the steel piston that the dry type cabinet is outer arch form structure by a cylinder type steel casing and surface is formed, piston is lifting in cylinder type, form the cylinder internal volume and changed the gas flow technological requirement that realizes the cabinet coal gas and the coal gas that offers for sale, a kind of device of confined piston movement warp is housed around piston, is called stator ring.This device has played the safety protection effect in dry type cabinet inner carrier floats the decline process, make its piston motion center minimum with the cylinder type cabinet centre deviation control that matches.This stator ring is existing application the in dry gas holder at present, but has following subject matter in using:
1, the rotating shaft means of fixation of stator ring component parts is the locking nut pattern, breaks away from rotating shaft generation production accident that comes off owing to the effect of rotation and vibration can make its locking nut at the volley.
2, the runner outer contour surface is shaped as straight line, with its contacted platen surface deviation phenomenon can take place at the volley, causes piston restraining force performance to reduce, and influences the normal location of piston lifting.
3, stud with axle sleeve between rotating shaft and the runner, use as easily damaged parts, this axle sleeve is a brass ware, and use exists friction serious, changes frequently, and the life-span is shorter, increases operating cost.
Summary of the invention
The purpose of this utility model is to provide a kind of stator ring device that is used for dry gas holder confined piston movement warp, has solved problem easily loosening between rotating shaft and runner, has movement locus and adjusts the center automatically.
The utility model comprises runner, baffle plate, bolt, packing ring, lubricating cup, screw, axle sleeve, rotating shaft, left bearing support, right bearing support.Rotating shaft penetrates in the internal diameter of axle sleeve, and uses screw attachment, and the rotating shaft two ends embed baffle plate, and left side baffle plate and the right baffle plate are separately fixed on left bearing support and the right bearing support with bolt, packing ring.Lubricating cup adopts scyewed joint at the external opening of rotating shaft hole.
Described axle sleeve is made by cemented carbide.
A cavity is opened at described rotating shaft center, and diameter is φ 3～5mm, and the path that lubricant grease forms along center hole is sent in the gap between axle sleeve and the rotating shaft, forms the lubricating condition between rotating shaft and the axle sleeve.
Described runner outer surface is the arc surface form, plays wear-resisting effect, and can adjust automatically, and the runner outer contour surface has tungsten carbide wear-resistant coating.
The utlity model has following advantage:
1, runner outer contour surface is fillet curve and spraying wear-resistant materials, by changing the material of axle sleeve, has reduced the wearing and tearing of rotating shaft, has prolonged the working life of rotating shaft;
2, rotating shaft means of fixation is the end plate means of fixation, has realized fixing accuracy, the reliability of rotating shaft, has reduced cost of production.
