Shaft seal


Torques,[link widoczny dla zalogowanych], because the torques will seal synchronous operation between the sealing surface damage, and ultimately lead to oil leakage. To avoid this problem, SPLITEX and MONEX seal material contained in devices manufactured by other manufacturers than the seals more than 0 ~ 6o This will ensure that the installation and operation of the seal device has a complete process of mutual contacts. Seal the outer sealing surface made of polished surface all round with no protruding parts. This design can be completely ruled out by fishing nets, ropes or other objects wrapped in danger. SPLITEX and MONEX Seal Another feature of the device is its flexible structure, it can in the space around the shaft under the conditions of very limited,[link widoczny dla zalogowanych], and very easy to install. For ease of installation, each SPLITEX and MON-EX seal according to user requests and sizes birth to a 2O a production. This design of the seal device can replace most of the existing board installed in various types of seal, regardless of the use of the old seal unit period style or design. The results have shown that too much use of the number of seal device need to be replaced after three to five years, with replacement of demolished when even the propeller shaft, which is expensive and time work. SPLITEX seal device with removable without removing shaft seal can be completed at the site of the demolition and installation. 』. . _ {. '1 L ---- Figure 5NYLAND replaceable shaft seal lubrication system CEDERVALL stern shaft seal leakage solid shaft seal is the owner who caused pollution in the pollution prevention a major problem faced, especially in the current implementation of the Environmental Protection Ordinance has been clear conditions. As the world merchant fleet to extend the useful life of the ship, must have a valid ship easily adapted to existing seal device cEDERvALL and SONER by the Swedish company developed the KP-type seal can be used as a cheap and effective replacement Other types of seal devices. As CEDERVALL stern shaft seal replacement-type short and has a length of detachable installation design features, without removing the shaft under the seal can be effectively modified. Propeller stern tube side and the distance between the fixed and determined from the ring accompanied by compensation. Given the location away from the ring configuration should correspond to existing mounting holes, that after the demolition of the existing seal was, CEDERVALL seal should be able to fit these mounting hole assembly. The conversion operation can cEDERVALL seal without removing the propeller shaft or the propeller in the removed conditions. Modified the seal is generally completed within 48 hours. When the ship mooring shaft seal can be adapted to carry out such operations. Figure 6CEDERVALL KP-type removable stern tube seal products into English from the land map {MarinePropulsionInternational \A 1991, (9/lo) Wu Chao issued the school (on the next page 16) (3) friction power of the new structure is smaller than the conventional structure, thus increasing the working life of the seal. (4) packing seal for water pump, pushing the anti-structure, so that the work of the media near the end of the pressing force to a value greater than the working pressure to avoid leakage of water with the water sediment easily enter the seal face to the serious abrasive wear phenomenon (j) the new structure can be adapted to large changes in the work under the pressure of work 5. Conclusions from the sealing industry,[link widoczny dla zalogowanych], domestic and international research on the mechanical seal type work more, and theory and structure matures; and research on the packing seal, such as packing rings have less axial pressing force distribution, radial distribution of clamping force, filling the lateral pressure coefficient of friction of the size of the axis of rotation, packing their own stress and other issues are not well resolved, especially for the combination of packing rings in a variety of operating conditions of the press-fit features which was also less involved in the dynamic characteristics. Therefore, this article on the traditional structure of the packing seal characteristics are analyzed, and the piston spring anti-pusher-type structure superimposed experimental analysis, the conclusion, at present,[link widoczny dla zalogowanych], some scholars at home and abroad have also mentioned the anti-packing push the structure,[link widoczny dla zalogowanych], but no complete testing methods and results, and most of the structure for reciprocating packing. In terms of work status, reciprocating and rotary packing seal packing seal is different, this article describes the structure packing anti-push type, can be extended to other rotating shaft seal on the application.
