Description
Technical field
The utility model relates to a kind of thermoelectricity plant reverse osmosis high-pressure high-temperature water mechanical sealing structure for pump.
Background technique
Thermoelectricity plant's reverse osmosis high-pressure high-temperature water pump parameter: medium: boiler circulating water; Pressure: 4.5Mpa; Temperature: 200 DEG C; Rotating speed: 2950r/min; The former use mechanical seal of this pump is UK type big spring balanced mechanical seal, and friction pair group is to being " cemented carbide-cemented carbide " (W-W), and this mechanical seal is contained on high pressure-temperature water pump, and working life only has 2 months, and more loaded down with trivial details when changing.
Summary of the invention
The purpose of this utility model is to provide a kind of thermoelectricity plant reverse osmosis high-pressure high-temperature water mechanical sealing structure for pump, can effectively prolonged mechanical sealing working life.
The purpose of this utility model realizes like this, a kind of thermoelectricity plant reverse osmosis high-pressure high-temperature water mechanical sealing structure for pump, the primary seal sealing configuration and the pair that are included in interval installation on axle sleeve are sealed seal structure, said primary seal sealing configuration comprises the primary seal rotating ring cemented carbide seal ring and the carbon seal ring of primary seal stationary ring arranged from outside to inside along main shaft, said pair is sealed seal structure and comprises the pair envelope rotating ring cemented carbide seal ring and the carbon seal ring of secondary envelope stationary ring arranged from inside to outside along main shaft, wherein the width of each carbon seal ring is all greater than the width of each cemented carbide seal ring.
The utility model is changed a social system machine envelope, change double mechanical seal into, major-minor envelope all adopts many spring balancings type machine to seal, and the friction pair group of major-minor envelope is to all using " graphite-cemented carbide " (M-W), because for the rotating speed of 2950r/min, adopt the comparatively reasonable of many springs, for high-temperature water, friction pair should use M-W's, machine envelope is installed on after on pump, so far, not there is leakage situation, substantially prolongs the working life of high-temperature water pump mechanical seal in running in 8 months.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is that master of the present utility model looks cross-sectional view.
Embodiment
A kind of thermoelectricity plant reverse osmosis high-pressure high-temperature water mechanical sealing structure for pump, as shown in Figure 1, the primary seal sealing configuration and the pair that are included in interval installation on axle sleeve are sealed seal structure, and primary seal sealing configuration is fixed by end cap 1, and pair is sealed seal structure and is fixed by spring capping 5.Said primary seal sealing configuration comprises the primary seal rotating ring cemented carbide seal ring 3 and primary seal stationary ring carbon seal ring 2 arranged from outside to inside along main shaft, and said pair is sealed seal structure and comprises the pair envelope rotating ring cemented carbide seal ring 4 and secondary envelope stationary ring carbon seal ring 6 arranged from inside to outside along main shaft.Wherein the width of each carbon seal ring is all greater than the width of each cemented carbide seal ring.
