Abstract
The utility model relates to a stop sealer for impurity pump, whose whole skeleton is composed of a seal box and an end cover. The utility model is characterized in that a centrifugal loose piece is inserted between the seal box and the end cover; a restoring spring is arranged in the cavity which is uniformly distributed on the end cover; the inner end of a moving ring is arranged in the sealer in half free state. The utility model cooperates with the dynamic sealing device of an auxiliary impeller, achieving the purpose of stopping without leakage. The stop sealer for impurity pump can be widely used for the occasions of conveying media with suspended particles, or with causticity, and valuable media.
Description
The utility model relates to the technical field of pump type seal, specifically a kind of transh pump parking sealer device.
At present, filler add high pressure water seal, mechanical seal and pay the impeller dynamic seal are mostly adopted in the sealing of pump class both at home and abroad, wherein pay the developing direction that the pump type seal technology is being represented in the impeller dynamic seal.Yet, the sealing when which kind of form all guarantees to drive only reliablely, and the problem that seals during the parking supporting with it never is resolved.
In modern industry was produced, transh pump was widely used in the wide field except that water medium, especially contained suspended particulate or was with corrosive medium (as H being used for conveying
3PO
4) and the occasion of valuable medium (selecting smelting factory as gold), more do not allow to leak.The dynamic (dynamical) basic principle of the ingenious utilization of the utility model has solved this difficult problem of pump class parking sealer, thus the perfect preferably impeller dynamic sealing device of paying.
The utility model is fitted to the rear portion of paying the impeller dynamic sealing device of pump main shaft.It mainly is made up of sealing case, end cap, centrifugal loose piece, spring, rotating ring, it is characterized in that sealing case and end cap constitute whole skeleton, the small end of several centrifugal loose pieces is inlayed by pin respectively and is distributed between sealing case and the end cap, several Returnning springs are placed in the uniform cavity of end cap, the inner of rotating ring is semi-free state and places sealer, and seal ring guarantees that then whole device is in good closed state.
Fig. 1 is the structural representation of transh pump parking sealer device.Below in conjunction with embodiment the utility model is further described, transh pump parking sealer device integral body shown in the drawings is fitted to paying between impeller dynamic sealing device (11) and the gland (12) of pump main shaft (14), and end cap (7) endoporus connects the formation drive fit with tight screw thread with pump main shaft (14).By A
3Sealing case of making (6) and end cap (7) are closely fixed with eight screws (15) and are constituted whole skeleton.The small end that is erose four the centrifugal loose pieces in big or small two ends (9) is inlayed by pin (4) respectively and is distributed between sealing case (6) and the end cap (7), is fixed by framework (10) and sell (4); Eight Returnning springs (5) are placed in end cap (7) and go up in the equally distributed cavity.The outer end of rotating ring (2) closely contacts and serves as a contrast the corrosion-proof wear-resistant material of answering rubber and high molecule plastic with paying impeller dynamic sealing device (11), and another part is used A for being embedded in tightly
3The section of making is in the inner of L shape, the inner of rotating ring (2) is connected with end cap (7) by pilot pin (8) and contacts with spring (5), be semi-free state and place sealer, O RunddichtringO (1), (3) guarantee that then whole parking sealer device is in good sealing state.
The sealing of pump is finished by paying impeller dynamic sealing device (1) during driving, the big end of several the centrifugal loose pieces (9) in the parking sealer device moves radially with pump main shaft (14) high speed rotating generation centrifugal force at this moment, thereby whole centrifugal loose piece (9) is rotated around pin (4), its small end is implemented pressure to rotating ring (2) under the effect of moment, it is slided to the right along pump main shaft (14), pressure spring (5) and break away to pay an impeller dynamic sealing device (11) separates with a pair impeller dynamic sealing device (11) when having realized driving.The centrifugal force that loose piece when pump stops (9) produces disappears, and spring (5) resets, and causes rotating ring (2) to be moved to the left with paying impeller dynamic sealing device (11) and contacts, and reaches the purpose of not leaking when stopping.
The utility model is not subjected to embodiment's restriction.
Claims (3)
1, a kind of transh pump parking sealer device is fitted to the rear portion of paying the impeller dynamic sealing device of pump main shaft.It mainly is made up of sealing case, end cap, centrifugal loose piece, spring, rotating ring, it is characterized in that sealing case and end cap constitute whole skeleton; Several centrifugal loose pieces are embedded between sealing case and the end cap; Several Returnning springs are placed in the cavity uniform on the end cap; The inner of rotating ring is semi-free state and places sealer.
2, by the described transh pump parking sealer of claim 1 device, it is characterized in that centrifugal loose piece is the irregular shape in big or small two ends, the small end of several centrifugal loose pieces is inlayed by pin respectively and is distributed between sealing case and the end cap.
