Abstract
The utility model relates to the mechanical sealing member of a disc spring in the field of a mechanical sealing member and is designed to solve the leakage problem caused by the lack of the floating compensation of the prior centrifugal pump. The sealing member includes a stationary ring gland connected with a pump body, a transmission pin, the O-shaped ring of a stationary ring, the stationary ring, a rotating ring, the O-shaped ring of the rotating ring, a thrust ring, a disc spring, a spring seat, a locating pin and a pump shaft and is mainly characterized in that the locating pin positioned inside the gland which is sleeved with the pump shaft causes the gland and the pump shaft in locating connection at the positioning place. The O-shaped ring of the stationary ring is arranged between the stationary ring gland and the stationary ring which contacts with the rotating ring. The O-shaped ring of the rotating ring is arranged in the groove of the rotating ring, between which and the spring seat the thrust ring and the disc spring are arranged. The utility model solves the technological problem of the sealing leakage because the utility model uses the disc spring as a floating compensation organization to cause a uniform force on the rotating ring and avoids that the mechanical sealing members of springs are damped easily, thereby affecting the elastic force of the spring and leading to the early failure of the sealing member.
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 video disc mechanical sealing element, 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 video disc spring mechanical seal, the sealing part comprises seal end plate, driving pin, stationary ring O shape circle, stationary ring, rotating ring, rotating ring O shape circle, throw-out collar, video disc spring, spring seat, locating stud, pump shaft, 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, and locating stud is located by connecting seal end plate herein with pump shaft; Stationary ring O shape circle is set between seal end plate and the stationary ring, and stationary ring touches mutually with rotating ring, and the groove of rotating ring is provided with rotating ring O shape circle, and throw-out collar, video disc spring are set between rotating ring and the spring seat.
It is joining that the rotation of the rotating ring of described video disc spring is that the groove by the both sides boss of spring seat and rotating ring both sides is symmetrical arranged, and rotating ring, throw-out collar and pump shaft are rotated synchronously.
By above-mentioned technological scheme, solved the technical problem of seal leakage.Rotating ring is stressed has evenly avoided many spring mechanical seals working state easily by the foreign material damping because the video disc spring as floating compensation mechanism, makes, and influences the elastic force of spring, the defective that causes Sealing to lose efficacy in advance.Moreover the video disc spring makes the performance of its end thrust comparatively stable.
Description of drawings
Fig. 1 is the utility model structural representation.
Sequence number and title among the figure: 1, seal end plate, 2, driving pin, 3, stationary ring O shape circle, 4, stationary ring, 5, rotating ring, 6, rotating ring O shape circle, 7, throw-out collar, 8, the video disc spring, 9, spring seat, 10, locating stud, 11, pump shaft, 12, the pump housing.
Embodiment
Mode of execution is installed as example with the utility model.By shown in Figure 1 spring seat 9, video disc spring 8, throw-out collar 7, rotating ring O shape circle 6, rotating ring 5, stationary ring 4, stationary ring O shape circle 3 are inserted in pump shaft 11, again by the fixedly connected pump shaft of fixing bolt (bolt of connection is not drawn), seal end plate 1 connects with pump 12 sports associations.During the rotation of pump shaft 11, rotating ring 5, throw-out collar 7 play the effect of compensation sealing in the rotation under the effect of the buffer shock-absorbing of video disc spring 8; Improved working life simultaneously.
