Technical field
The utility model relates to a kind of ISG vertical pipeline mounted pumps with mechanical seal grease chamber, belong to centrifugation delivery pump technology neck
Domain.
Background technique
The mechanical seal of current tradition ISG vertical pipeline mounted pump is mounted between impeller and pump cover (i.e. in pump chamber), from the external world
The liquid medium of extraction is directly entered machine and is sealed intracavitary, can only convey the liquid medium without solid particle or impurity, even if
Contain minute quantity solid particle or impurity in the medium of extraction, then the solid particle or impurity in liquid medium are also easily accessible
In the abrasive end face of dynamic and static two ring for being sealed envelope to machine, end face is caused to grind away too early, machine envelope failure, pump can not work normally.
In addition, if liquid medium pumping is not come up, the phenomenon that machine runs in the case where being enclosed in no-cooling-water, dry friction is caused to burn out also when
There is generation, the service life of mechanical seal is 8000 hours or more under normal circumstances, and many ISG vertical pipeline mounted pumps are because extract medium
Containing fixed particle, cause mechanical seal premature failure, pump is caused to break down.Even if the use of mechanical seal being titanium alloy, carbon
Change the high-intensity sealings ring such as tungsten, not only increased costs, and machine is sealed service life of envelope and can not be guaranteed well.
Utility model content
According to the above-mentioned deficiencies in the prior art, technical problem to be solved by the utility model is: one kind is provided can be to prevent
The only ISG vertical pipeline mounted pump with mechanical seal grease chamber of mechanical seal damage, can convey the liquid containing solid particle or impurity
Body medium, and can be to avoid the generation of dry friction phenomenon.
ISG vertical pipeline mounted pump described in the utility model with mechanical seal grease chamber, including the pump housing, the pump housing is interior to be equipped with leaf
Wheel, impeller top are equipped with pump cover, and pump shaft is coaxially disposed through pump cover and with impeller, and axle sleeve, axle sleeve and impeller are arranged with outside pump shaft
Rotated synchronously with pump shaft, the pump cover has cavity, be equipped with machine sealed cover above pump cover, pump cover, axle sleeve and machine sealed cover it
Between form a grease chamber, lubricating oil is full of in grease chamber；At the rotation connection of pump cover and axle sleeve, the rotation of machine sealed cover and axle sleeve connects
The place of connecing is equipped with mechanical seal, and the stationary ring of mechanical seal is separately fixed on pump cover and machine sealed cover, and the rotating ring of mechanical seal is equal
It is fixed on axle sleeve, compressed spring is equipped between two rotating rings.
A grease chamber is formed between pump cover, axle sleeve and machine sealed cover, is full of lubricating oil in grease chamber, mechanical seal is in grease chamber
Interior, the rotating ring of mechanical seal is rotated with axle sleeve, pump shaft when work, forms effective oil in seal face with fixed stationary ring
Film completes end face seal, ensure that the leakproofness of pump chamber, prevent the leakage of extracted liquid.And grease chamber is machinery
Sealing establishes suitable working environment, and abrasion loss is reduced when mechanical seal being made to work, extends the service life of mechanical seal,
Mechanical seal avoids solid particle and impurity from entering machine and is sealed in envelope in oily office work, contains solid particularly suitable for conveying
The liquid medium of grain and impurity, and under any state, mechanical seal does not have the appearance of dry friction situation, significantly reduces pump
Failure rate.
The pump cover is equipped with tank filler sleeve and drain oil, and tank filler sleeve and drain oil are respectively provided with filler plug and bleeder plug, side
Just it refuels, drain the oil, make in grease chamber full of clean lubricating oil.
It is equipped with sealing ring between the machine sealed cover and pump cover, is further ensured that the leakproofness of grease chamber.
The machine sealed cover is fixed on pump cover by fastening screw.
Possessed beneficial effect is the utility model compared with prior art:
ISG vertical pipeline mounted pump described in the utility model with mechanical seal grease chamber extends the use longevity of mechanical seal
Life, mechanical seal are difficult to enter machine and are sealed in envelope in oily office work, solid particle and impurity, avoid traditional ISG pipeline pump
To the rigors for extracting medium, particularly suitable for conveying the liquid medium containing solid particle and impurity；And under any state, machine
Tool seals the appearance for not having dry friction situation, significantly reduces the failure rate of pump, has very strong economy and practicability.
