Abstract
A special hydraulic tool for installation and disassembly of a cantilever type impeller mainly comprises an adjusting nut capable of being connected with an impeller center bolt in matching mode, an inner cylinder and an outer cylinder which are mutually matched are sleeved in the adjusting nut, and an oil pressure cavity communicated with an external hydraulic pump is formed between an inner cylinder sleeve and an outer cylinder sleeve. A sleeve capable of abutting against the impeller end wall is connected with the connection center bolt side of the adjusting nut through threads. An inner sealing ring and an outer sealing ring are arranged at the position of the connection gaps at two ends of the inner cylinder sleeve and the outer cylinder sleeve, and a poking rod capable of being matched with an impeller locking nut in matching mode and locking the impeller locking nut is configured on the sleeve. The special hydraulic tool has the advantages of being simple in structure, light in weight, capable of providing large axial force, convenient to install and disassemble and the like.
Description
Technical field
The present invention relates to the dedicated hydraulic frock of a kind of cantilevered impeller installation and removal, be particularly useful for the installation and removal of the cantilevered impeller of nitrogen compressor, air compressor machine.
Background technology
Twin shaft, three nitrogen compressors and air compressor machine adopt the cantilevered impeller usually, and impeller adopts bolt to be connected with splendid the wheel, and transmits moment of torsion through end face pin or triangle axle.The centre bolt of impeller need guarantee that bigger axial tightening force could realize that impeller and splendid mating surface of taking turns closely cooperate.Because the particularity of twin shaft, three nitrogen compressors and air compressor machine structure, need the frock of design to have to provide larger axis to tightening force, simple in structure, in light weight and installation, convenient disassembly characteristics, existing frock can't satisfy above-mentioned requirements.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, the dedicated hydraulic frock of larger axis to tightening force, simple in structure, in light weight and installation and removal cantilevered impeller installation and removal easily can be provided and provide a kind of.
The objective of the invention is to realize through following technical scheme; It mainly includes the adjustment nut that can be connected with the impeller centre bolt; Be inserted in inner cylinder body and the outer cylinder body that cooperatively interacts on this adjustment nut, and between inner cylinder liner and outer cylinder sheath, be formed with the oil pressure cavity that is connected with the peripheral hardware hydraulic pump; The adjustment nut connect the centre bolt side with screw thread be connected with one can withstand the impeller end wall sleeve.
In the described oil pressure cavity, be connected the seam place with respect to the two ends of inner cylinder liner and outer cylinder sheath and be provided with inner seal ring and exterior seal ring respectively; Disposing one on the described sleeve can cooperate with the impeller locking nut and with the driving lever of its locking.
That the present invention has is simple in structure, in light weight, can provide larger axis to characteristics such as power, installation and removal are convenient.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is an installation example schematic of the present invention.
The specific embodiment
To combine accompanying drawing that the present invention is done detailed introduction below: shown in Figure 1; The present invention mainly includes the adjustment nut 3 that can be connected with impeller centre bolt 11; Be inserted in the inner cylinder liner that cooperatively interacts 5 and outer cylinder sheath 6 on this adjustment nut 3, and between inner cylinder liner 5 and outer cylinder sheath 6, be formed with the oil pressure cavity 4 that is connected with the peripheral hardware hydraulic pump; The adjustment nut connect centre bolt 11 sides with screw thread be connected with one can withstand impeller 10 end walls sleeve 7.
In the described oil pressure cavity 4, be connected the seam place with respect to the two ends of inner cylinder liner 5 and outer cylinder sheath 6 and be provided with inner seal ring 1 and exterior seal ring 2 respectively; Disposing one on the described sleeve 7 can cooperate with impeller 10 locking nuts 9 and with the driving lever 8 of its locking.Impeller 10 shown in the figure is taken turns 12 and is linked to each other with splendid through centre bolt 11; Common described locking nut is special nut, and above content is existing technology contents, does not do more detailed explanation.
When external hydraulic pump provided certain oil pressure, sleeve 7, inner cylinder liner 5 and outer cylinder sheath 6, adjustment nut 3 oppositely moved vertically, and the axial tension that needs is provided, and elongate the centre bolt 11 of impeller 10.When taking off hydraulic pressure frock 13, the centre bolt 11 of impeller 10 extends and the axial elasticity restoring force of generation, can guarantee that impeller 10 and splendid 12 mating surfaces (end face pin or triangle axle) of taking turns closely cooperate.The locking nut 9 that it should be noted that impeller 10 is a special nut, on the nut side, has locating hole, can be through driving lever 8 this locking nut 9 of screwing.
Shown in Figure 2, the at first centre bolt 11 of mounted impeller 10, impeller, end face pin, and the tight locking nut 9 of prewhirling; Second step, hydraulic pressure frock 13 is installed, guarantee that the sleeve 7 of hydraulic pressure frock 13 well contacts with the impeller hub front end face, the adjustment nut 3 of screwing must guarantee that the centre bolt 11 of adjustment nut 3 and impeller 10 has certain screwing length; The 3rd step, utilize hydraulic pump to provide needed charge oil pressure is installed, outer cylinder sheath 6 moves vertically with sleeve 7 and compresses impeller 10 under the oil pressure effect, the centre bolt 11 of inner cylinder liner 5 and adjustment nut 3 counter motion vertically tension impeller 10; The 4th step, with driving lever 8 locking nut 9 of screwing, turn down the hydraulic pump charge oil pressure, unclamp and adjust nut 3, take off hydraulic pressure frock 13.Process and the similar process of mounted impeller of dismounting impeller, different is the former for unclamping locking nut, the latter is fastening locking nut.
