Abstract
The utility model relates to a mechanical sealing element with a locating bearing for an agitator, which is designed with the aim at the known problem of the leakage of sealing slurry. The sealing element comprises a movable ring, a static ring, a spring, a static ring sleeve, a gland, a shaft sleeve, a bearing, a locating ring, and a locking ring. The utility model is characterized in that the bearing is arranged between the gland and the shaft sleeve which are connected through the agitator shaft for locating, the spring installed in the gland is propped against the static ring, the moving ring is fixed at one end of the shaft sleeve and makes frictional rotation relative to the static ring, the other end of the shaft sleeve is connected with the agitator shaft through a screw rod, is connected with the locking ring through a fixing bolt, and synchronously rotates with the agitator shaft, so as to form integrated sealing. Through the improvement on the spring protection and the locking mechanism for the ordinary mechanical sealing element, and by replacing the ordinary mechanical sealing element with the design of the bearing positioning and lubricating oil injection, the utility model solves the technical problem of the sealing leakage of the mechanical sealing element of the agitator.
Description
Technical field
The utility model relates to mechanical sealing element.Particularly, be a kind of be installed in corollary equipments such as stirrer or reactor, be used to prevent seal the mechanical sealing element that slurry leaks.
Background technique
At present, in fields such as petrochemical industry, rubber, papermaking, pharmacy, electric power, metallurgy, required material is generally stirred by stirrer, the slurry that stirs is transported in the manufacturing mechanism of formulating operation again.In order to prevent to leak, the slurry between equipment cavity and running shaft must be installed Sealing.And existing stirrer mechanical sealing element does not reach leak free requirement, influences the requirement of production technology, causes some unstable product quality.Make the good brand of providing quality goods or brilliant, defective because of this mechanical sealing element restricted the exploitation of new product, the development of enterprise.
Summary of the invention
The utility model will overcome above-mentioned deficiency, and purpose provides a kind of stirrer mechanical sealing element with positioning bearing, make it can solve the technical problem of seal leakage.The purpose of this utility model is to adopt following technological scheme to realize.
A kind of stirrer mechanical sealing element with positioning bearing, this mechanical sealing element comprises rotating ring, stationary ring, spring, stationary ring cover, gland, axle sleeve, bearing, positioning ring, locking ring, its main points are to mix between gland that the device axle connects and the axle sleeve bearing location are set, the spring and the stationary ring that are installed in the gland offset, rotating ring is fixed on axle sleeve one end and does relative friction rotation with stationary ring, the axle sleeve the other end connects stirrer shaft by positioning ring by screw rod, and connect with stirring shaft by fixing bolt by locking ring and to rotate synchronously, constitute cartridge seal.
Described stationary ring is installed in the gland, stationary ring cover and spring, and O shape circle E links, and by the space that stationary ring cover, O shape circle E constitute a relative closure, protects spring not to be subjected to the impurity damping.
In the described spring spring pin being set, is when protecting spring to be subjected to moment of torsion and the spring that fractures.
Described gland is provided with oil hole, makes and forms a grease chamber between stationary ring and the axle sleeve.Between gland and axle sleeve, constitute the grease chamber of sealing, reach the lubrication and seal appearance.The spacers outside framework oil seal moves axially, and outside framework oil seal stops oil to external leakage.The jump ring rigid bearing moves axially; Between gland and the axle sleeve by the relative swing of bearing restriction to influence sealed precision.Limiting stopper guarantees the installation dimension of cartridge seal part.
The bearing location is set between described gland and the axle sleeve, is to prevent that the excessive swing of the relative axle sleeve of gland from influencing sealed precision.
Described axle sleeve is connected by screw rod with positioning ring, and connects positioning ring by the locking ring that is provided with by fixing bolt, prevents that screw rod is loosening.
Described stationary ring bottom is with throw-out collar, and the protection stationary ring is cracked owing to impact.
Between described gland and the stationary ring isolation pad being set, is to prevent from that mud is deposited in O shape circle C was lost efficacy.
To the improvement of conventional machinery Sealing at spring protection, locking mechanism, the design by bearing location and injection lubricant oil has replaced the conventional machinery Sealing, has solved the technical problem of stirrer mechanical sealing element seal leakage by above-mentioned.
