Description
Technical field
The utility model relates to advanced manufacturing technology field more particularly to a kind of disassembly of impeller pump screw thread mechanical seal and
Mounting device.
Background technique
It from rotor pump shaft disassembly main method is beaten using sledgehammer by pump with mechanical seal in the prior art, this method is held
It easily leads to rotor pump shaft and generates axial bending hidden danger, the operational reliability of impeller pump is influenced after dress is multiple；Most serious can also be led
It causes rotor pump shaft to scrap, leads to that subsequent maintenance is at high cost, difficulty is big.
Summary of the invention
Of the existing technology to overcome the problems, such as, it is mechanical that the purpose of the utility model is to provide a kind of lobed rotor pump screw threads
The disassembly and installation device of sealing, device has its peculiar structure of screw thread mechanical seal, easy to disassemble and install, improves mechanical close
The service life and service efficiency of envelope.
Lobed rotor pump screw thread mechanical seal cooperates adjusting machine to seal seal friction auxiliary air gap by rotating ring and axle thread,
To reach the function of sealing.Its peculiar structure of screw thread mechanical seal, design specialized disassemble and install device.To guarantee that machine seals
When assembly or disassembly, it is uniform axially and radially to transmit torque.Improve the service life and service efficiency of mechanical seal.
The disassembly and installation device of a kind of lobed rotor pump screw thread mechanical seal of the utility model, by sleeve and hand lever group
At；The sleeve is cylindrical tube, and sleeve ends Milling Process is at the teeth shape matched with mechanical sealing linkage ring；The sleeve
Tail portion is drilled with the hole for being inserted into hand lever.
Further, described hand lever one end is reserved with end.
Further, the diameter in hole for being inserted into hand lever and the ratio of hand lever length are 1:(10 ~ 15).
Further, sleeve outer diameter 20-50cm, internal diameter 18-48cm；The ratio of the length of the outer diameter and hand lever of sleeve
For 1:(2.5-9).
Further, hand lever and the hole for being inserted into hand lever are interference fit；Sleeve ends teeth shape and mechanical seal
Rotating ring is interference fit.
Sleeve and hand lever scantling are calculated through the mechanics of materials checks, and is required with proof strength.
Compared with the existing technology, the utility model has the following advantages that and the utility model has the advantages that can guarantee mechanical seal assembly
When with disassembly, it is uniform axially and radially to transmit torque.Improve the service life and service efficiency of mechanical seal.
Detailed description of the invention
Fig. 1 is the disassembly and installation device axial section of the utility model lobed rotor pump screw thread mechanical seal；
Fig. 2 is the disassembly and installation device assembling schematic diagram of the utility model lobed rotor pump screw thread mechanical seal.
Appended drawing reference: 1, sleeve；2, hand lever；3, sleeve ends；4, hole；5, end；6, mechanical seal；7, rotating ring.
Specific embodiment
Referring to Fig. 1, Fig. 2, the disassembly and installation device of the lobed rotor pump screw thread mechanical seal of the utility model is by sleeve 1
It is formed with hand lever 2；The sleeve 1 is cylindrical tube, and 3 Milling Process of sleeve ends is matched at the rotating ring 7 with mechanical seal 6
Teeth shape；1 tail portion of sleeve is equipped with the hole 4 for being inserted into hand lever 2.
The utility model passes through the teeth for matching setting 3 Milling Process of sleeve ends at the rotating ring 7 with mechanical seal 6
Shape realizes mechanical snap, and cooperates hand lever 2, when enough guaranteeing mechanical seal assembly and disassembly by lever principle, axially and radially
It is uniform to transmit torque.
It in addition, hand lever one end is reserved with end 5, penetrate hand lever 2 can only unidirectionally, anti-upper hand lever 2 skids off hole 4.
The diameter in hole 4 and the ratio of 2 length of hand lever for being inserted into hand lever 2 are 1:(10 ~ 15), hand lever can be made strong in this way
Degree reaches requirement, and rotates the most laborsaving when hand lever.
The size of sleeve 1 is not particularly limited, such as outer diameter is 20-50cm, internal diameter 18-48cm；The outer diameter of sleeve 1 with
The ratio of the length of hand lever 2 is 1:(2.5-9), hand lever intensity can be made to reach requirement, while preferably utilizing lever principle.
Hand lever 2 is interference fit with the hole 4 for being inserted into hand lever 2；The rotating ring 7 of sleeve ends 3 teeth shape and mechanical seal 6
For interference fit, in order to assemble and mechanical snap.
Obviously, the above embodiments of the present invention is merely examples for clearly illustrating the present invention, and
It is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
Exhaustion.Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc., should be included in
Within the protection scope of the utility model claims.
