Description
Technical field
The utility model belongs to machinery equipment field, is related to a kind of machine joint sealing, is specifically related to desulfurization pump machine joint sealing knot
Structure.
Background technology
Desulfurization pump is the pump with wear-resisting and decay resistance, is mainly used in the conveying with corrosivity slurry.Tradition is de-
Sulphur pump, which generally uses the mechanical seal of built-in type single-shaft-sleeve, i.e. mechanical seal, to be installed from the lateral atmospheric side of medium, together
When need to increase sealing gasket and sealed, mechanical seal is directly installed on axle.This conventional machine joint sealing and machine sealed knot configuration
Formula, one side installing/dismounting is inconvenient, and sealing gasket sealing effectiveness is bad, drainage easily occurs, on the other hand, pump rotor portion
The adjustment of part can influence the decrement of the dynamic and static ring of mechanical seal, influence sealing effectiveness.
The content of the invention
The utility model is in order to solve the above technical problems, there is provided a kind of simple in construction, convenient disassembly, good sealing effect
Desulfurization pump machine joint sealing structure.
The technical solution adopted in the utility model is：A kind of desulfurization pump machine joint sealing structure, including machine joint sealing, machinery are close
Envelope, pump shaft and pump shaft sleeve, the mechanical seal include rotating ring, stationary ring, machine envelope axle sleeve, spring, machine sealed cover, oil sealing, O-ring and
Retaining ring, the machine joint sealing seals seat provided with machine, the machine envelope seat is positioned with machine sealed cover by seam and bolt is fixedly connected,
Sealed simultaneously by O-ring；The machine envelope axle sleeve is fixedly connected by retaining ring with pump shaft sleeve, and machine envelope axle sleeve lower end is set
It is fluted, machine is sealed the junction formation space of axle sleeve and pump shaft sleeve；The spring is located inside machine sealed cover, and spring passes through machine
Sealed cover and throw-out collar are compressed；The oil sealing is arranged on machine sealed cover（8）In chamber, carried out by oil sealing baffle plate spacing.
Further, the rotating ring is embedded on machine envelope axle sleeve, and is fixed by pin；The stationary ring is embedded in machine envelope pressure
Cover.
Further, the machine joint sealing and machine sealed cover are level connection joint.
Further, clamping ring, two retaining rings are further fixed on described retaining ring point or so two panels, the machine envelope axle sleeve
It is each attached on clamping ring, and is fixedly connected between two retaining rings by bolt.
Further, the number of springs at least one.
What the utility model was obtained has the beneficial effect that：The utility model is simple in construction, realizes from air direction finding side medium
The frame mode of installation, greatly improves installation effectiveness.
Machine joint sealing is positioned with machine sealed cover by seam and bolt is fixedly connected, while being sealed by O-ring, structure
Simple and good sealing effect.Machine, which is sealed, is provided with pump shaft sleeve between axle sleeve and axle, because of rotor axial regulation mechanical seal will not be caused to rub
The variation of secondary decrement is wiped, makes the operation of pump relatively reliable.Spring is located inside machine sealed cover so that spring does not connect with medium
Touch, extend the service life of spring, it is ensured that mechanical sealing linkage ring, stationary ring decrement will not spring change and cause
The change of its decrement, so as to ensure that sealing effectiveness.Retaining ring is by the inclined-plane lock shaft on clamping ring, so as to ensure that just
Often the tight fit of the machine envelope axle sleeve and axle during operating, will not occur dislocation rotation.
