Abstract
The utility model relates to the mechanical sealing member of a conical spring in the field of a mechanical sealing member and is designed to solve the leakage problem between a rotating ring and a pump shaft, as well as between a stationary ring and a stationary ring gland caused by the lack of the floating compensation of the prior centrifugal pump. The sealing member includes an O-shaped ring, the stationary ring, the rotating ring, the O-shaped ring of the rotating ring, a thrust ring, a conical spring, a locating pin, the stationary ring gland connected with a pump body, the pump shaft, a locating ring and a fixing bolt and is mainly characterized in that the stationary ring gland which is sleeved with the pump shaft is equipped with the locating pin inside, the O-shaped ring is arranged between the stationary ring and the stationary ring gland, the rotating ring is arranged between the stationary ring and a rotating ring seat, the O-shaped ring of the rotating ring and the thrust ring are arranged at the connecting part of the rotating ring seat and the pump shaft, and a conical spring is arranged between the thrust ring and the locating ring which is fixedly connected with the pump shaft by the fixing bolt. The utility model uses the conical spring as a floating compensation organization and avoids the resonance phenomenon generated by the high speed rotation of the pump shaft which causes a bad contact of the friction surfaces of the stationary and rotating rings, thereby solving the technological problem of the sealing leakage caused by the bad contact.
Description
Technical field
The utility model relates to the mechanical sealing element field, is applicable to the sealing of centrifugal pump.
Background technique
At present, mechanical sealing element is widely used in the sealing that centrifugal pump is carried various liquid, but mechanical sealing element design fashion does not take into full account the compensation problem of centrifugal pump auxiliary seal.Especially lack floating compensation mechanism, cause the leakage between rotating ring and pump shaft and stationary ring and the seal end plate.
Summary of the invention
The utility model will overcome above-mentioned deficiency, and purpose provides a kind of cone of mechanical Sealing, 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 volute spring mechanical sealing element, the sealing part comprises O shape circle, stationary ring, rotating ring, rotating ring O shape circle, throw-out collar, volute spring, locating stud, seal end plate, pump shaft, positioning ring, fixing bolt, seal end plate connects with the pump housing, its main points are in the seal end plate that is nested of pump shaft locating stud to be set, O shape circle is set between seal end plate and the stationary ring, between stationary ring and the rotating seat rotating ring is set, the junction of rotating seat and pump shaft is provided with rotating ring O shape circle, throw-out collar, between throw-out collar and the positioning ring volute spring is set, positioning ring is by the fixedly connected pump shaft of fixing bolt.
The outer eave tile of described volute spring one end is connected with the groove of rotating seat, and the other end is connected with positioning ring, and rotating ring, throw-out collar and pump shaft are rotated synchronously.
By above-mentioned technological scheme, solved the technical problem of seal leakage.Because the resonance phenomenon that volute spring as floating compensation mechanism, has avoided the pump shaft high speed rotating to be produced causes rotating ring and the bad connection of stationary ring rubbing surface, leak and produce.
Description of drawings
Fig. 1 is the utility model structural representation.
Sequence number and title among the figure: 1, O shape circle, 2, stationary ring, 3, rotating ring, 4, rotating ring O shape circle, 5, throw-out collar, 6, volute spring, 7, locating stud, 8, seal end plate, 9, pump shaft, 10, positioning ring, 11, fixing bolt, 12, rotating seat.
Embodiment
Mode of execution is installed as example with the utility model.By Fig. 1 O shape circle 1, stationary ring 2, rotating ring 3, rotating ring O shape circle 4, throw-out collar 5, volute spring 6, locating stud 7, seal end plate 8, positioning ring 10 are inserted in pump shaft 9, by fixing bolt 11 fixedly connected pump shafts, seal end plate 8 connects (bolt, the pump housing that are connected are not drawn) with the pump housing again.During the rotation of pump shaft 9, rotating ring 3, throw-out collar 5 play the effect of compensation sealing in the rotation under the effect of the buffer shock-absorbing of volute spring 6; Improved working life simultaneously.
