Reductor lubricating oil cooling system.
Background technology
Reductor plays matching rotating speed between prime mover and working machine or executing agency and transmits torque, reductor
It is a kind of machinery of precision relatively, the use of its purpose is reduction rotating speed, increases torque.In reductor operation to oil temperature requirement very
Height, when finding oil temperature temperature rise more than 80 DEG C or oil sump temperature should stop more than 100 DEG C and when producing the phenomenons such as abnormal noise
Use, check reason.
In some special application scenarios, it is necessary to which the work of reductor continuous-stable, avoids stopping for improper maintenance as far as possible
Machine, such as in desulphurization system, desulfurization slurry needs continuous circulation, and slurry circulating pump will need continuous firing, serum recycle
Often temperature is higher for the working environment of pump, is that the reductor cooling system of this slurry circulating pump must be definitely reliable.Once slurries
Circulating pump is not normally functioning because of reductor, it is possible to is caused the desulfuration efficiency of desulphurization system to decline, is caused discharge beyond standards.Though
The slurry circulating pump of some right desulphurization systems can hold a standby design using one, but reductor lubricating oil temperature is too high, often
It is due to what external environment was caused, if not taking effective cooling provision, the reductor of standby slurry circulating pump is same
Working environment under can also occur the situation of high oil temperature quickly.
Tradition has following several for the type of cooling of reductor lubricating oil：

Casing and heat exchange with outside mainly by reductor realize the natural cooling of lubricating oil in casing, and casing is not as
When can meet cooling requirements, typically meeting outside the enclosure sets up radiated rib, and the setting of radiated rib can make air accelerate nature
Circulation.But, for ambient temperature it is higher in the case of, its cooling effect is unsatisfactory.
2. fan coolling
The natural cooling for depending merely on casing can not meet require when, it is general using the cooling of fan auxiliary heat dissipation, but fan
Air flow and circulation rate can only be accelerated, its cooling effect is still not ideal enough.
3. water cooling
The mode of water cooling is installs snakelike conduit in the oil sump of reductor, and snakelike conduit is typically by red copper or brass system
Into, pipe in be connected with cooling water, a part of heat of lubricating oil is taken away by cooling water circulation.Although can be more natural using water cooling
Cooling and fan coolling have higher efficiency, but are constrained to the internal structure of reductor, it is impossible to set too big too long of snakelike
Pipe, thus cause heat exchange area to be necessarily restricted, once lubricating oil temperature is quickly raised, water cooling but also be difficult to meet cooling
Demand.
