Description

A kind of environment-friendly type serum recycle pump group

Technical field

The utility model relates to circulating pumps, more particularly to a kind of environment-friendly type serum recycle pump group.

Background technique

Environment-friendly type serum recycle pump group group belongs to single-stage single-suction horizontal centrifugation mashing pump, is mainly used for Coal-fired group Wet method fume desulfurizing system, aluminium manufacturer's alumina decomposition circulatory system and other serum recycle systems.The separation of flow of Wet Flue Gas Desulfurization Technique It is high-efficient, it is national Coal-fired group focus on the application separation of flow technology, and the decomposition of aluminium oxide, then it is the important generation work of aluminium manufacturer Skill process.Environment-friendly type serum recycle pump group group belongs to key in wet flue gas desulfurizer and the alumina decomposition circulatory system Equipment.

In wet method fume desulfurizing system, the medium of pump group conveying is that lime stone slurry either gypsum slurries, slurries are dense Degree is 15%~40%, and density is 1100kg/m3~1500kg/m3, and temperature is 35 DEG C~65 DEG C, and Cl content is about 15000ppm ~60000ppm, slurries are 0.03mm~0.1mm containing solid partial size, and slurries also contain other acid and alkali corrosions during the separation of flow Medium；In aluminium manufacturer's alumina decomposition circulatory system, the medium of pump group conveying is aluminum hydroxide slurry, alkali concentration Nk be 170g/l~ 250g/l, pulp density: 1650kg/m3~1850kg/m3, solid content are 800kg/m3~1000kg/m3, work normally temperature 60 DEG C~75 DEG C of degree；Temperature is 120 DEG C when alkali cleaning, and alkali concentration is 300g/l~500g/l when alkali cleaning.China's vast area, ground Domain circumstance of temperature difference is larger, and the running environment temperature difference of environment-friendly type serum recycle pump group group is larger, generally between -40 DEG C~45 DEG C.

Since environment-friendly type serum recycle pump group group belongs to key equipment, the safety and stability fortune of pump group in above-mentioned process system Row is extremely important.In addition the characteristic of pump group pumped (conveying) medium, environment-friendly type serum recycle pump group group belong to heavy service equipment, operation temperature Degree is relatively higher, and the leakage of slurries is very big to the pollution of environment.In existing environment-friendly type serum recycle pump group technology, either All-metal type structure or semimetal add ceramic mould structure or semimetal to add rubber-type structure, all only study, solve the resistance to of pump Grind corrosion resistant performance or efficiency of pump performance etc., and and not adequately addressed environment-friendly type serum recycle pump group group whole synthesis maneuverability The pollution problem of the dielectric leakages to environment such as energy and slurries.

In the prior art, environment-friendly type serum recycle pump group group is due to being not provided with bearing cooling system, when pump group operates in In i.e. hot environment or when conveying high-temperature medium, bearing temperature is increased, because without cooling bearing, can reduce pump group service life or Damage pump group.When in pump group cold environment in sight, because not preheating to bearing, pump can be damaged when pump group starts moment Group；Due to being not provided with pump chamber cooling system, in the environment that pump group runs heat in sight or when conveying high-temperature medium, pump chamber and machine The temperature for sealing chamber increases, when the concentration of pumped (conveying) medium or excessive partial size and when pump discharge pipeline builds the pressure, pump chamber and machine sealing chamber Temperature increases again, because pump group service life or damage pump group can be reduced without cooling pump chamber, machine sealing chamber and pump holder, and There are great operational safety hidden danger for pump group.In pump group cold environment in sight or when transporting low temperature medium, because not to pump chamber, Machine sealing chamber and pump holder are preheated or are kept the temperature, and can damage pump group when pump group starts moment or operation.

In the prior art, environment-friendly type serum recycle pump group group is due to being not provided with grease chamber water ingress detection system, if pump group is oily Room cannot then judge in time when intaking, to reduce pump group service life；Because being not provided with lubricating oil temperature detection system, if pump It cannot judge in time when group high oil temperature, to reduce pump group service life；Because being not provided with mechanical seal leakage detection system, There are operational safety hidden danger for pump group；Due in existing environment-friendly type serum recycle pump group, pumping the axial force of generation all with balance hole knot Structure, is unable to the axial force of complete equipilibrium pump, and residual axial force is born by bearing.When water pump operation is in off-design behaviour, this A little residual axial forces are very big, and very big destruction can be generated to bearing, seriously affects the service life of pump；It is taken out due to being not provided with It send that remaining, leaking medium arranges residual system and residual system is arranged in oil leak, environment can be caused greatly to pollute, very not ring It protects.
