Abstract
A double-end mechanical sealing device used for a water pump is arranged on a pump shaft (3) of a water pump (7). A double-end mechanical seal (5) is sheathed inside a sealing casing (4), and the sealing casing (4) filled with lubricating oil is sealed and fixed by a sealing gland (6). A static ring (9) sheathed on a rubber sealing ring (8) is respectively assembled with a male end (K) of the sealing casing (4) and a spigot (H) of the sealing gland (6) by interference fit. A flange (P) of the sealing gland (6) is fixed on the end face of the opening of the sleeve (2) so as to encapsulate the double-end mechanical seal (5) and the sealing casing (4) into the sleeve (2). Using the lubricating oil in the sealing casing (4) to cool and lubricate, the device reduces frication coefficient and working temperature. In addition, the adopted duplex sealing structure strengths sealing performance, reduces power loss, and improves the working efficiency of the water pump (7).
Description
Technical field
The utility model relates to water pump, relates in particular to the seal arrangement of water pump.
Background technique
The seal form of present water pump, the general mode that adopts asbestos or asbestos to add seal with elastometic washer, newer have employing stationary ring, rotating ring add the single face mechanical seal structure of rubber ring, and stationary ring is fixed on the axle sleeve, the rotating ring lock ring is on pump shaft, phenomenons such as rubbing surface uses though these modes can guarantee water pump by water cycle cooling, and ubiquity gas leakage, insufficient lubrication, frictional loss are big, power loss is more, the flow and the lift of restriction water pump need often keep in repair, change, and influence utilization efficiency.
Summary of the invention
The purpose of this utility model just provides a kind of and the supporting seal arrangement of water pump, improves structure, improves the cooling and lubricating operating mode, reduces power loss, improves pump efficiency.
Task of the present utility model is finished like this: design a kind of water pump double end-face mechanical sealing device, be installed on the pump shaft of water pump, double mechanical seal is sleeved in the capsul, pour into lubricant oil in the capsul, seal fixing by the sealing gland cooperation.Double mechanical seal adopts ceramic double mechanical seal structure.Capsul is the cylinder type hollow cylindrical shell, and opening end has the limit circle, has axis hole on the outer stopper end face of bottom.Capsul can adopt transparent rigid plastics to make.Sealing gland is the metal flange dish of band seam, and the flange plate center has axis hole, uniform some mounting holes on the circumferential surface of axis hole outer rim.The equal suit rubber seal of the stationary ring at double mechanical seal two ends is pressed the interference fit close fit with the bottom outer stopper of capsul, the seam of sealing gland respectively.The seam of sealing gland cooperates with the opening end suit of capsul, double mechanical seal is enclosed in the capsul, flange plate is fixed on the end face of axle sleeve opening, and the double mechanical seal of suit on the pump shaft and capsul are encapsulated in the axle sleeve on the pump body.Cover double mechanical seal in the capsul, be sleeved on the inner of pump shaft, perfusion lubricant oil in the capsul, the sealing gland of cover stationary ring is encapsulated in the opening end of capsul in the seam, stage clip in the middle of the double mechanical seal is compressed, the stationary ring of double mechanical seal is contacted with rotating ring compress, pass the inner opening end face that mounting hole on the flange plate disc is fastened on sealing gland on axle sleeve with bolt.The rotating ring lock ring rotates with pump shaft on pump shaft, and with the stationary ring end-face friction, by the lubricant oil in the capsul cool off, lubricated.Owing to all install stationary ring on capsul and the sealing gland, formed two-layer sealing configuration, strengthened sealing effect greatly, guaranteed the suction journey and the stable raising of lift of water pump.
Design and produce according to above-mentioned, the utility model is fitted on the water pump, carries out cooling and lubricating by the lubricant oil in the capsul, has improved operating mode, has reduced friction factor and operating temperature; Adopt the structure of double mechanical seal, strengthened sealability, reduced power loss, improved the working efficiency of water pump, reached predetermined purpose preferably.
