Abstract
The utility model relates to a container type mechanical sealing device comprising a static ring and a dynamic ring, wherein the dynamic ring is sleeved on a shaft sleeve; the static ring is installed at one end of the dynamic ring; the static ring is sleeved in an O-shaped ring of a static ring seat; an anti-rotating pin is arranged at the other end of the static ring; one end of the anti-rotating pin is installed on a mechanically sealed gland; a spring is installed at the inner side of the mechanically sealed gland and is connected with one end of the static ring through a thrust ring; an oil seal is arranged on the right end of the shaft sleeve; a sealing ring gasket is arranged in front of the oil seal; and a water inlet and a water outlet are formed on an inner gland. As the static ring and the dynamic ring form an integrated silicon carbide structure, meanwhile the spring is externally arranged and is not in contact with mediums, the spring is prevented from being blocked by the particle mediums and corrosively damaged by corrosive mediums. The arranged anti-rotating pin of the static ring is capable of preventing the static ring from rotating and capable of pre-compressing the spring through the thrust ring and capable of preventing the static ring, which is ejected by the spring when the container type mechanical sealing device is dismounted, from being damaged. As the sealing gasket is additionally arranged in front of the oil seal, the pressure of cooling water on the oil seal can be reduced, and the sealing life of the cooling water can be prolonged.
Description
Technical field
The utility model relates to a kind of mechanical seal device, particularly a kind of integrated mechanical sealing device.
Background technique
At present a kind of corrosion resistant commonly used, wear-resisting, withstand voltage integrated mechanical sealing device on engineering plastic pump, though through many improvement, but rotating ring stationary ring section easy abrasion produces security incident takes place when revealing easily.Simultaneously, the sealing section is cooled off, need to inject cooling water, but cooling water can only be charged to the position of shaft centre line, if pressurization, cooling water will flow out from sealing part, so the sealing section can not get cooling off fully, descend to sealing life.Also have present integrated mechanical sealing device installation, adjustment cumbersome, require workman's technical merit high, particularly when user's maintain and replace easily damaged parts, inconvenience is arranged, also possibly cause some assembly quality problems, influence the reliability of machine envelope.
The model utility content
The utility model technical problem to be solved is to overcome that rotating ring stationary ring section easy abrasion in the existing technology, sealing life descend, install, adjustment is cumbersome and a kind of integrated mechanical sealing device is provided.
For the technical problem that solves the utility model adopts following technological scheme:
A kind of integrated mechanical sealing device comprises stationary ring and rotating ring, and said moving ring sleeve is contained on the axle sleeve; Said rotating ring one end is installed stationary ring, and said stationary ring is sleeved in the O type circle of stationary seat, and the said stationary ring the other end is provided with a stop pin; Said stop pin one end is installed on the machine sealed cover; In said machine sealed cover inboard spring is housed, said spring is connected with an end of stationary ring through throw-out collar, at the right-hand member of axle sleeve oil sealing is set; Be provided with sealed loop-pad in said oil sealing front, water intake and water outlet are set on internal gland.
Said rotating ring and stationary ring are whole silicon carbide structure.
Rotating ring and stationary ring that the utility model adopts are the structure of whole silicon carbide, have corrosion resistance, wear resistance is good, can satisfy the corrosion-resistant face width of engineering plastic pump characteristics, can anti-all kinds of diluted acid clear liquids, can anti-various ore pulps, feed liquid etc. contains granule medium.Adopt spring external simultaneously, do not contact, prevent that the particulate species medium is to the obstruction of spring and the Korrosionsmedium corrosion failure to spring with medium.The layout of stationary ring stop pin both can prevent that stationary ring rotated, and can pass through the throw-out collar pretensioned spring again, and spring ejects stationary ring and suffers extremely destruction in the time of can preventing to tear machine open.Before oil sealing, increase by one sealing gasket, can reduce the pressure of cooling water, prolong cooling water sealing life oil sealing.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description:
As shown in the figure, a kind of integrated mechanical sealing comprises the rotating ring 2 that is sleeved on the axle sleeve 1; One end of rotating ring 2 is installed stationary ring 3; Rotating ring 2 is designed to whole silicon carbide structure with stationary ring 3, has corrosion resistance, characteristics that wear resistance is good simultaneously, can satisfy the characteristics of the corrosion-resistant face width of engineering plastic pump; Simultaneously can anti-all kinds of diluted acid clear liquids, again can anti-various ore pulps, feed liquid etc. contains granule medium.Stationary ring 3 is adjacent to rotating ring and is connected with O type circle and stationary seat are unsteady.The other end at stationary ring 3 is installed stop pin 6, and stop pin 6 one ends are installed on the machine sealed cover 5.In machine sealed cover 5 inboards spring 10 is housed, spring 10 is connected with an end of stationary ring 3 through throw-out collar 11.The structure of spring 10 externals does not contact with medium, prevents that the particulate species medium is to the obstruction of spring 10 and the Korrosionsmedium corrosion failure to spring 10.At the right-hand member of axle sleeve 1 oil sealing 8 is installed, polytetrafluoroethylsealed sealed circle pad 7 is installed in oil sealing 8 fronts, can reduce the pressure of cooling water to oil sealing, prolongs cooling water sealing life.The water outlet 13 of water intake 9 and another side is set on machine sealed cover 5.
Screw 12 is that the above-mentioned stationary seat that has assembled each part is connected with machine sealed cover 5, is inserted in the axle sleeve 1 that connects rotating ring again, and the jump ring of card Upper shaft sleeve 1 right-hand member had both become whole integrated mechanical sealing.
Claims (2)
