Description
Technical field
The utility model relates to a kind of sealing configuration of turbine-generator units stator Intermediate shaft sleeve, specifically a kind of large-scale mixed turbine-generator units stator Intermediate shaft sleeve sealing configuration.
Background technique
At present, stator Intermediate shaft sleeve is only provided with inside and outside two seals structure, and inner seal structure encloses for being arranged on Intermediate shaft sleeve lower end axle YX, and inner seal structure is motive sealing, and outer seal configuration is for being arranged on Intermediate shaft sleeve lower end O type circle, and outer seal configuration is static seal.Because inner seal structure is motive sealing, therefore the probability of damage of inner seal structure is higher, Intermediate shaft sleeve, when changing inner ring Sealing (YX circle), need eject, and remove upper bush by prior art, and then put into complete inner ring sealing, above-mentioned prior art is more complicated, and the workload changing Sealing is comparatively large, and the replacement cycle is longer, efficiency is lower, is therefore necessary to improve.
Summary of the invention
The purpose of this utility model is the deficiency in order to overcome background technique, and provides a kind of large-scale mixed turbine-generator units stator Intermediate shaft sleeve sealing configuration.
To achieve these goals, the technical solution of the utility model is: large-scale mixed turbine-generator units stator Intermediate shaft sleeve sealing configuration, comprise the Intermediate shaft sleeve be arranged on top cover and the self oiling bearing be arranged on inside Intermediate shaft sleeve, Intermediate shaft sleeve outer wall upper end is provided with connecting hole, Intermediate shaft sleeve outer wall lower end is provided with O RunddichtringO, Intermediate shaft sleeve inwall lower end is provided with YX RunddichtringO, it is characterized in that: described Intermediate shaft sleeve inwall upper end is provided with seal groove, the square packing of multiple arranged stacked is installed in seal groove, described multiple square packing upper end is closely fitted with the flange being arranged on Intermediate shaft sleeve upper end, mounting hole on flange is corresponding with the connecting hole of Intermediate shaft sleeve upper end, multiple square packing lower end and self oiling bearing fit tightly.
The utility model, by setting up square packing in Intermediate shaft sleeve inwall upper end, reaches the object of setting up one sealing, effectively can ensure the sealing effect of Intermediate shaft sleeve.When overhauling, the utility model only needs the flange opened on Intermediate shaft sleeve and changes square packing, does not need Intermediate shaft sleeve to eject, and does not also need to remove upper bush, effectively can reduce the labor intensity changed and seal.Meanwhile, as urgency, the utility model can change square packing when runner does not disappear pressure, reaches the object improving Intermediate shaft sleeve sealing effect further.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model, and wherein, the attachment bolt on the left of plan view and square plate do not draw.
1-Intermediate shaft sleeve in figure, 2-self oiling bearing, 3-top cover, the connecting hole on 4-Intermediate shaft sleeve, 5-O RunddichtringO, 6-YX RunddichtringO, 7-seal groove, the square packing of 8-, 9-flange, the connecting hole on 10-flange.
Embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not form to restriction of the present utility model, only for example.Make advantage of the present utility model clearly and easy understand by explanation simultaneously.
Accompanying drawings is known: large-scale mixed turbine-generator units stator Intermediate shaft sleeve sealing configuration, comprise the Intermediate shaft sleeve 1 be arranged on top cover 3 and the self oiling bearing 2 be arranged on inside Intermediate shaft sleeve 1, Intermediate shaft sleeve 1 outer wall upper end is provided with connecting hole 4, Intermediate shaft sleeve 4 outer wall lower end is provided with O RunddichtringO 5, Intermediate shaft sleeve 1 inwall lower end is provided with YX RunddichtringO 6, it is characterized in that: described Intermediate shaft sleeve 1 inwall upper end is provided with seal groove 7, the square packing 8 of multiple arranged stacked is installed in seal groove 7, described multiple square packing 8 upper end is closely fitted with the flange 9 being arranged on Intermediate shaft sleeve 1 upper end, mounting hole 10 on flange 9 is corresponding with the connecting hole 4 of Intermediate shaft sleeve 1 upper end, multiple square packing 8 lower end and self oiling bearing 2 fit tightly.
The utility model be outer seal configuration in existing Intermediate shaft sleeve basis on improve, the utility model lower half portion to Intermediate shaft sleeve is not changed, Intermediate shaft sleeve top process a seal groove, and the square packing of multiple stacked setting is installed in seal groove, namely on existing inner seal structure basis, add one sealing again, thus improve sealing effect of the present utility model.Simultaneously, the utility model adds flange as separate part on Intermediate shaft sleeve top, and make the connecting hole of mounting hole on flange and Intermediate shaft sleeve upper end to hole, set up flange and not only can fix Intermediate shaft sleeve, and square packing can be compressed, and then improve practicability of the present utility model and sealing effect further.
In practical work process, Intermediate shaft sleeve, top cover and flange are linked together by attachment bolt.In discovery seal leak, staff directly can remove upper flange, and changes square packing, does not need Intermediate shaft sleeve to hang out, and the utility model reduces work difficulty when changing Sealing, decreases workload.
Other unaccounted part all belongs to prior art.
