Description
Technical field
The invention belongs to the technical field of swivel joint, particularly relate to a kind of swivel joint for water cooled rolls.
Background technology
In the industry such as iron and steel, papermaking, apply more water cooled rolls, working environment or the workpiece temperature of contact residing for roll body are higher, in order to roll body is lowered the temperature, reduce the temperature of roll body bearing simultaneously, improve bearing service life, chilled(cooling) water return (CWR) is set inside roll body, be connected with cooling down aqueous phase in roll body end.Because roll body does circumference rotary motion, and cooling water pipeline maintains static, it is necessary to installs swivel joint and connects the roll body home loop of fixing cooling water pipeline and rotation.
In the factory of steel industry, typical water cooled rolls is the water-cooled furnace roller of annealing furnace, the water-cooled contact roll body such as roller, water-cooling tower top roller, the operating ambient temperature of these roll bodies is from 300 degrees Celsius to 900 degrees Celsius, even higher, carrying out the circulation in a cycle from the cooling water of roll body end input inside roll body, take away partial heat, cold in-water temperature is generally below 35 degrees Celsius, leaving water temperature is up to 60-75 degree Celsius, and roll body bearings at both ends and bearing block temperature control are below 85 degrees Celsius.
When cooling water system breaks down, water temperature in roll body inner loop loop will continue to rise, even up to boiling point, the temperature of bearing and bearing block also rises rapidly therewith, lubricant grease temperature also rises therewith, runs once the bearing length time is under the condition of high temperature, and the life-span will sharply decline, even can be damaged, cause a series of fault.
The swivel joint life-span domestic at present is shorter, main cause is each component manufacturing accuracy of swivel joint, assembly precision is general, sealing ring material is basic identical with imported product, but owing to overall precision is general, the ring portion of sealing ring and stationary ring part discontinuity equalization, abrasion is very fast, and local infiltration, the water that seepage overstocks rotates along with joint, the bearing within swivel joint may be penetrated into, cause bearing lubrication oils and fats emulsion deterioration, after time is permanent, lubricant grease lost efficacy, bearing produces corrosion, gap increases, reduce the kinematic accuracy of rotary part, exacerbate the abrasion of sealing ring, swivel joint drainage occurs rapidly.
Summary of the invention
The technical problem to be solved is in that for above-mentioned Problems existing, it is provided that a kind of swivel joint for water cooled rolls, ensures the running precision of swivel joint, extends the service life of swivel joint.
nullThis invention address that above-mentioned technical problem be the technical scheme is that a kind of swivel joint for water cooled rolls，It is characterized in that，Including anchor tip、Fixing housing、Rotate housing、Bearing、Bearing block、Spring、Sliding seat、Fixing seal ring and rotating seal ring，Described anchor tip is connected with one end of described fixing housing，The other end of fixing housing is connected with described bearing block，Described bearing is located between bearing block and described rotation housing，And be connected by back-up ring location，Described sliding seat is fixed on the inwall of fixing housing by adjusting bolt，Described both ends of the spring offsets with fixing housing and sliding seat respectively，Described fixing seal ring is embedded on the end face of sliding seat，Described rotating seal ring is embedded on the end face rotating housing，The setting corresponding with rotating seal ring of fixing seal ring，The bottom of fixing housing is provided with outlet.
By such scheme, described bearing medial extremity is provided with lip-type packing.
By such scheme, described bearing block is provided with grease fitting.
By such scheme, described fixing seal ring and rotating seal ring are made by carborundum.
By such scheme, between described sliding seat and described fixing inner walls, it is provided with O RunddichtringO.
The invention has the beneficial effects as follows: 1, a kind of swivel joint for water cooled rolls is provided, by the pressure of presetting spring, fixing seal ring and rotating seal ring close contact can be made, and after sealing ring produces certain abrasion, spring extends, and makes up wear extent, increases the service life；2, set up lip-type packing at bearing block medial extremity, bearing block inner chamber is sealed further, reduce cooling water and immerse bearing, ensure bearing running precision, ensure the running precision of swivel joint, extend the service life of swivel joint.
