Abstract
The utility model discloses a safety control mechanism in a lubricating and cooling system of a coal pulverizer. The lubricating and cooling system of the coal pulverizer comprises an oil tank, an oil pump communicated with the oil tank, an oil inlet pipeline connected from the oil pump to the speed reducer of the coal pulverizer, an oil return pipeline connected from the speed reducer of the coal pulverizer to the oil tank, wherein an oil return branch pipeline directly communicated with the oil tank is connected to the oil inlet pipeline, and a safety valve is arranged on the oil return branch pipeline. The safety control mechanism provided by the utility model plays a safe control effect to the lubricating and cooling system of the entire coal pulverizer, avoids oil circuit blockage which causes the oil pump to be burnt out, and ensures that the lubricating and cooling system can still run unceasingly in case that the oil pump goes wrong.
Description
Technical field
The utility model belongs to the coal pulverizer technical field, relates in particular to the coal pulverizer lubricating and cooling system.
Background technology
Coal pulverizer is with coal crusher and wears into the machinery of coal dust that it is the important auxiliary equipment of coal-powder boiler.Coal pulverizer is in running, and its reductor can generate heat and easy abrasion, normally moves for guaranteeing coal pulverizer, is necessary to the reductor cooling and is lubricated.But present coal pulverizer lubricating and cooling system only is to the reductor fuel feeding through a petroleum pipeline.In the lubricating and cooling system actual moving process, might cause the obstruction of the pipeline of lubricating and cooling system owing to fault, if stop up, oil pump works on and can cause oil pump to burn out easily.In case oil pump breaks down, whole system just paralysis can't be worked.
The utility model content
The utility model technical problem to be solved provides a kind of safety guarantee mechanism that when oil circuit take place to stop up, avoids in the lubricating and cooling system that oil pump burns out, to overcome the deficiency that prior art exists.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
Safety guarantee mechanism in a kind of coal pulverizer lubricating and cooling system; Said coal pulverizer lubricating and cooling system comprises fuel tank; The oil pump that is communicated with fuel tank is connected to the in-line of coal pulverizer reductor from oil pump, is connected to the return line of fuel tank from the coal pulverizer reductor; It is characterized in that: connect the oil returning branch pipe road that directly is communicated to fuel tank on the said in-line, said oil returning branch pipe road is provided with safety valve.
In addition, said fuel tank also is communicated with emergency bearing oil pump, and said emergency bearing oil pump also is connected in the in-line.Through adopting an emergency bearing oil pump parallelly connected,, can also start emergency bearing oil pump like this, thereby guarantee the unlikely paralysis of whole system in case oil pump breaks down with oil pump.
For guaranteeing that lubricating cooling oil is not back to the phenomenon of oil pump and emergency bearing oil pump, said oil pump and emergency bearing oil pump are provided with check-valves at the oil-out place.
Adopt above technical scheme, the utility model plays the safety guarantee effect to whole coal pulverizer lubricating and cooling system, has avoided because the oil circuit obstruction causes oil pump to burn out and guaranteed can also continue when oil pump breaks down operation.
Description of drawings
Be elaborated below in conjunction with accompanying drawing and specific embodiment the utility model:
Fig. 1 is the coal pulverizer lubricating and cooling system structure chart of the utility model;
Among the figure:
The 101-fuel tank, 102-oil pump, 103-emergency bearing oil pump, 200-coal pulverizer reductor, 300-in-line, 301-oil returning branch pipe road, 400-return line, 500-safety valve, 600-check-valves.
The specific embodiment
As shown in Figure 1; Safety guarantee mechanism in the coal pulverizer lubricating and cooling system of the utility model; Wherein the coal pulverizer lubricating and cooling system comprises fuel tank 101; The oil pump 102 that is communicated with fuel tank 101 is connected to the in-line 300 of coal pulverizer reductor 200 from oil pump 102, is connected to the return line 400 of fuel tank 101 from coal pulverizer reductor 200.Safety packaging mechanism is provided with safety valve 500 on in-line 300, to connect the oil returning branch pipe road 301 that directly is communicated to fuel tank 101 on oil returning branch pipe road 301.Under normal circumstances, safety valve 500 is in closed condition all the time, in case oil circuit stops up; Oil pressure in the in-line 300 will raise; Surpass safety valve 500 setting values (for example 8bar) when oil pressure raises, at this moment, safety valve 500 is opened; Let the oil in the in-line 300 directly let out in the fuel tank 101, thereby play the effect of protection oil pump 102.
In addition, fuel tank 101 also is communicated with emergency bearing oil pump 103, and emergency bearing oil pump 103 also is connected in the in-line 300.Through adopting an emergency bearing oil pump 103 parallelly connected,, can also start emergency bearing oil pump 103 like this in case oil pump 102 breaks down with oil pump 102, thus the unlikely paralysis of assurance whole system.
And oil pump 102 is provided with check-valves 600 with emergency bearing oil pump 103 at the oil-out place.Through being set, check-valves 600 can avoid taking place the phenomenon that lubricating cooling oil is back to oil pump 102 and emergency bearing oil pump 103.
Through above-mentioned detailed description, can find out that the utility model plays the safety guarantee effect to whole coal pulverizer lubricating and cooling system, avoided because the oil circuit obstruction causes oil pump to burn out and guaranteed can also continue when oil pump breaks down operation.
But; Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model, as long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
