Description
Technical field
The invention belongs to speed reducer lubrication system field, be applicable to the lubrication system of industry speed reducers such as metallurgy, ore, cement.
Background technique
Need good lubricating also in time to carry out good heat exchange during speed reducer work, lubrication system is the indispensable constituent element of speed reducer proper functioning.In the traditional design, speed reducer generally adopts bath lubrication or the lubricated mode of forced feed, and these two kinds of lubricating systems each have its pluses and minuses, are presented below respectively:
Bath lubrication: inject a certain amount of lubricant oil in the speed reducer, gear parts directly is immersed in the lubricant oil; Speed reducer is provided with oil inlet and outlet, is connected with return opening with the lubricating fitting oil-feed port respectively, forms closed circulation system, and during equipment operation, the high temperature grease in the speed reducer enters in the speed reducer after cooling off by lubrication station again.This kind lubricating system oil mass abundance, heat radiation in time, the lubricant oil that flows can be taken away in the speed reducer partial impurities and filter through lubricating fitting, makes gear obtain fully, lubricate reliably.Shortcoming is to be not suitable for to shut down in extremely frigid zones or winter maintenance, and low temperature very easily makes lubricant oil freeze attached on gear and the casing and not easy-clear, the replacing inconvenience of lubricant oil simultaneously.
Forced feed is lubricated: speed reducer is equipped with the lubrication station of band fuel tank, lubricant oil by lubrication station with certain pressure pumping, be dispensed to each lubricating point in the speed reducer, get back to fuel tank from return opening again and cool off, filter.This kind lubricating system can be taken away heat, and pressure oil can wash away the metal granule of friction surface and filter out.Shortcoming is that the lubricants capacity of each point and pressure must obtain monitoring, and it is lubricated reliably to guarantee that gear obtains, and the output pipe more complicated is very high to the oil product requirement, otherwise oil circuit is blocked easily, causes gear to can not get lubricating timely and damaging; And lubrication station needs the double pump system and the supervisory system cost thereof of setting higher for guaranteeing pressure.
Summary of the invention
The objective of the invention is to: a kind of novel speed reducer lubrication system is provided, has the advantage of the lubricated dual mode of bath lubrication and forced feed concurrently, reduce cost of equipment.
The object of the invention realizes by following technical proposals:
A kind of speed reducer lubrication system, comprise the speed reducer, pump-unit and the fuel tank that are provided with oil inlet and outlet, described speed reducer oil outlet is linked to each other with pump-unit import and fuel tank respectively by the oil outlet three-way valve by pipeline, described pump-unit import also connects fuel tank by valve, and described pump-unit outlet is linked to each other with speed reducer filler opening and fuel tank respectively by the filler opening three-way valve by pipeline.
As optimal way, be provided with fluid level controller, heater and temperature transducer in the described fuel tank and link to each other with control system.
As optimal way, described speed reducer oil outlet to the pipeline between the oil outlet three-way valve is provided with stop valve.
As optimal way, the pipeline that described pump-unit is exported between the filler opening three-way valve is provided with safety valve, differential pressure transmitter device, filter, flow indicator, thermometer, heat exchanger, pressure meter switch, pressure gauge and temperature transducer.
As optimal way, described oil outlet three-way valve to the pipeline between the pump-unit import is provided with thermometer.
As optimal way, the pipeline that described filler opening three-way valve links to each other with fuel tank is provided with filter.
As optimal way, described three-way valve is threeway four seal ball-valves.Threeway four seal ball-valves can make three passages be interconnected, and also can close arbitrary passage, make two other channel connection.
Beneficial effect of the present invention: the advantage that has the lubricated dual mode of bath lubrication and forced feed concurrently.When speed reducer normally moved, fuel tank and speed reducer and pump-unit disconnected, and pump-unit is communicated with formation bath lubrication mode with speed reducer, and it is lubricated reliably to guarantee that speed reducer obtains; Long-time shut down or during maintenance, fuel tank is communicated with pump-unit and speed reducer, but lubricant oil natural back flow or be pumped to fuel tank, the assurance speed reducer obtains good lubricating under low temperature environment.Compare with bath lubrication, the assurance that more is easy to get of the quality of lubricant oil, practical region and repair time are wider, and more oil change is more convenient; Compare with forced feed is lubricated, oil feed line is simpler, controls easylier, and water environment capacity is stronger, and single-pump system and easy supervisory system make its cost lower.
