Abstract
The utility model discloses a special tool for dismounting a mechanical seal sleeve of a centrifugal pump, which is used for dismounting the mechanical seal sleeve of the centrifugal pump and is convenient for replacement of routine maintenance of the mechanical seal sleeve of the centrifugal pump. The special tool comprises two locating rods, an ejecting screw, a supporting block and a locking mechanism, wherein the two locating rods are inserted in the supporting block and the locking mechanism, and the ejecting screw is screwed in an ejecting screw mounting hole arranged between the two locating rods and positioned on the supporting block. The mechanical seal sleeve is clamped through the locking mechanism, and the mechanical seal sleeve is detached from the pump shaft of the centrifugal pump through rotating the ejecting screw. The special tool disclosed by the utility model not only facilitates the daily maintenance of the centrifugal pump and ensures safe operation of the equipment, but also has good protection effect to the mechanical seal of the centrifugal pump and reduces the maintenance expenses of the equipment.
Description
Technical field
The utility model relates to the dismounting device of centrifugal pump mechanical seal cover, and particularly centrifugal pump mechanical seal cover dismounting special tool is used for the dismounting of centrifugal pump mechanical seal cover, has made things convenient for the replacing and the daily maintenance of centrifugal pump mechanical sealing mechanism.
Background technique
Centrifugal pump is widely used in petroleum industry, as pipeline delivery source powered device, is a kind of supercharging equipment commonly used in the crude oil gathering system, also is the core drive equipment in the crude oil exporting system.Mechanical seal cover and mechanical sealing mechanism are housed above the pump shaft of centrifugal pump, and in running, mechanical sealing mechanism belongs to the rapid wear accessory need be to its frequent replacing, necessary first disassembly mechanism stuffing box gland during replacing.But in the process that mechanical sealing mechanism is changed; Owing to be not specifically designed to the special tool of the mechanical stuffing box gland of dismounting; When changing mechanical sealing mechanism, all to the mechanical seal cover slowly be dug out at every turn, so not only prolong the maintenance replacing time, the mechanical seal cover is damaged easily with bottle opener.
Summary of the invention
The purpose of the utility model is to make centrifugal pump mechanical seal cover dismounting special tool, and centrifugal pump mechanical seal cover is dismantled, and makes things convenient for the running repairs maintenance of centrifugal pump.
The purpose of the utility model is achieved in that centrifugal pump mechanical seal cover dismounting special tool comprises positioning rod, jackscrew, support block and locking mechanism; Two positioning rods are set in support block and the locking mechanism, jackscrew screw between two positioning rods, be arranged in the jackscrew mounting hole on the support block.Through locking mechanism clamping mechanism stuffing box gland, the mechanical seal cover is separated with the centrifugal pump pump shaft through rotating jackscrew.
Compared with prior art the utlity model has following useful effect: the utility model has solved the dismounting difficult problem of centrifugal pump mechanical seal cover effectively, has made things convenient for the replacing of centrifugal pump mechanical sealing mechanism.Not only make things convenient for the running repairs maintenance of centrifugal pump, guaranteed equipment safety operation, on the other hand centrifugal pump mechanical seal cover has been played good protective action, reduced the apparatus maintenance expense.
