Abstract
The utility model relates to a kind of propene carbonate purifications to be pumped with decarburization, including the pump housing (1) and main shaft (2), the pump housing (1) both ends are equipped with bearing shell, and main shaft (2) connect cooperation with bearing shell, it is characterised in that: the bearing shell is replaced with divergence type N-1232 tapered roller bearing (3).The utility model has the advantages that the following: 1, improving the decarburization pump operation period, reduce repair rate after to decarburization pump transformation.2, the consumption of machine material is reduced, each class will add 15kg or so machine oil before not being transformed, and not need to add now, nearly 190,000 yuan of 1 year save the cost (15 × 3 × 365 170 × 2000 yuan of ÷).3, security risk risk is reduced, is solved because of decarburization pump operation time long bearing bush abrasion, causes lubricating oil to bring propene carbonate into and enter and blocks packed tower in decarbonization system.4. reducing the period of packed tower cleaning, employee labour is reduced, reduces external coordination resource, reduces human cost.
Description
Technical field
The utility model belongs to purifying ammonia process equipment, is related to a kind of propene carbonate purification and is pumped with decarburization.
Background technique
In Ammonia Production, since gas raw material processed is mainly carbon and nitrogenous compound, through gas processed and carbon monodixe conversion
Afterwards, it is removed in conversion gas and contains the hydrogen etc. useful to ammonia synthesis, while also containing carbon dioxide, carbon monoxide, methane, hydrogen sulfide
Deng to gases such as ammonia synthesis, again with the content highest of carbon dioxide in these impurity compositions.Such as in process of production, not in time
Carbon dioxide is removed from conversion gas, it will be normally carried out subsequent handling can not.
Propylene carbonate ester process is a kind of decarbonization method that propene carbonate is absorbent, and the medium of decarburization pump operation is exactly
Propene carbonate, in process of production, often there is pump and bearing shell 3a serious wear, operation week in bearing shell formula decarburization pump operation before
Frequently, there is tile kilning situation in phase short maintenance when serious；Simultaneously watt with axis wear when will cause by lubricating oil bring into decarburization pump in, with
Impurity contact is easy blocking filler, to bring security risk to Chemical Manufacture.
Utility model content:
The purpose of this utility model is exactly to will cause when solving existing watt of the pump of decarburization in the prior art with axis abrasion
Lubricating oil is brought into and contacts the defect for being easy blocking filler in decarburization pump with impurity, a kind of purification provided is pumped with decarburization, improved
Equipment operation stability, reduces security risk risk, while saving lubrication oil consumption, the machine material of greatly reducing disappears
Consumption.
The technical solution of the utility model is as follows:
A kind of propene carbonate purification is pumped with decarburization, including the pump housing and main shaft, and pump housing both ends are respectively equipped with supports main shaft rotation
The rotary support member and its sealing element turned, and the end cap by pump body end surface is arranged in is fixed, it is characterised in that: by rotation branch
Support member is divergence type N-1232 tapered roller bearing.
In addition, based on the above technical solution, every end pump housing is equipped with tank filler sleeve, tank filler sleeve and divergence type N-
1232 tapered roller bearing cavity one end connection, end cap is equipped with oil outlet and divergence type N-1232 tapered roller bearing is empty
Chamber other end connection.The tank filler sleeve and oil outlet are required to setting sealing-plug.
For stabilizing equipment operation, decarburization pump is transformed, separated type N-1232 tapered roller bearing is used.Usually
It uses, is symmetrically installed in pairs.The inside and outside circle of bearing all has tapered raceway, and roller is truncated cone-shaped.Roller is contacted with raceway for line
, heavier radial and axial joint load can be born, purely axial load can also be born.Contact angle is bigger, and axial carrying capacity is got over
It is high.Tapered roller bearing uses reinforced structure, and roller diameter increases, and roller length lengthens, and roller number increases, and adopts
With the roller with convexity, thus significantly improve the bearing capacity of bearing and fatigue life.Between roller large end face and large-flange
Using spherical surface and taper-face contact, lubrication is improved, filling a lubricating grease by tank filler sleeve can be used 2 years or more.
The utility model has the advantages that the following after to decarburization pump transformation:
1, the decarburization pump operation period is improved, repair rate is reduced.
2, the consumption of machine material is reduced, each class will add 15kg or so machine oil before not being transformed, and be not required to now
Add, nearly 190,000 yuan of 1 year save the cost (15 × 3 × 365 170 × 2000 yuan of ÷).
3, security risk risk is reduced, solves because of decarburization pump operation time long bearing bush abrasion, lubricating oil is caused to bring carbon into
Acid propylene rouge, which enters, blocks packed tower in decarbonization system.
4. reducing the period of packed tower cleaning, employee labour is reduced, reduces external coordination resource, reduces human cost.
Detailed description of the invention:
Fig. 1 is the decarburization pump configuration figure of the utility model.
Specific embodiment:
As shown in Figure 1, a kind of propene carbonate purification is pumped with decarburization, including the pump housing 1 and main shaft 2,1 both ends of the pump housing are set respectively
The rotary support member and its sealing element 7 for thering is supports main shaft 2 to rotate, and the end cap 6 by pump body end surface is arranged in is fixed, by the rotation
Turning supporting element is divergence type N-1232 tapered roller bearing 3.Every end pump housing is equipped with tank filler sleeve 5, tank filler sleeve and divergence type N-
1232 tapered roller bearing, 3 cavity one end connection, end cap 6 are equipped with oil outlet 4 and divergence type N-1232 tapered roller bearing
3 cavity other end connection.
1, pump shaft bearing shell position is pumped to former decarburization first and bush seat is transformed, and wanted according to bearing NU2312 type technology
It is realistic to apply transformation.2, primitive axis tile style pump pump shaft is replaced with bearing-type pump shaft.3, according to pump principle and technical specification assembly pump and
Bearing etc..4, pass through dynamic balance running and actual use, it was demonstrated that the type pump after technological transformation using effect and service life and
Technical requirements are more superior than before not being transformed.
