Abstract
The utility model discloses an external lubricating system of lodz fan relates to the lubricated technical field of fan. The utility model discloses there are an oil tank, oil pump and emergency bearing oil pump, the oil feed end of oil tank through advancing oil pipe connection lodz fan lubricating system, lodz fan lubricating system's the end that produces oil is connected to the oil tank through an oil pipe, oil pump and emergency bearing oil pump inhale the oil pipe way all with oil tank intercommunication, the row oil pipe way of oil pump and emergency bearing oil pump all with advance oil pipe and communicate, the row oil pipe of oil pump and emergency bearing oil pump all installs the valve on the road, advances and installs the manometer on the oil pipe. The advantage: through this external lubricating system, use to appear so far because of the shut down that the lubricating system trouble produced, lengthened the life of lodz fan, very obvious reduction accidental shutdown numbers of lodz fan (except the annual overhaul), the plant maintenance volume that has significantly reduced is moved for whole coal gas system security and is provided reliable guarantee.
Description
Technical field
The utility model relates to Lodz blower fan lubrication technical field, specifically a kind of Lodz external fan lubrication system.
Background technique
What a lot of gas fan used at present is all Lodz blower fan, because of the heart that gas fan is whole coke-oven plant coal gas system, blower fan need be switched when gas fan overhauls, in reversed process, because of gas pressure fluctuation coke oven pneumatic trough pressure transient thus there will be slight phenomenon of burning with anger of smoldering, bring pollution to environment.
In the use of Lodz blower fan, mainly to maintenance and the maintenance of the lubrication system of Luo Fengji, the lubrication system of Lodz matched with blower utilizes the driven shaft end of the machine as the power input shaft of oil pump, oil pump is gear pump, be arranged on body, by carrying out transmission to wheel, oil pressure is observed by the oil pressure gauge on oil water heat exchange device, the rotating speed of blower fan is 560 turns/min, the oil pressure of oil pump is 0.3Mp, the lubrication system of usual Lodz blower fan breaks down, as oil pump damages (not having emergency bearing oil pump), lubricant oil is dirty, must shut down and overhaul, because the lubrication system of Lodz blower fan and fan body are one, like this because of a glitch of lubrication system, just must carry out switching blower fan to overhaul.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of Lodz external fan lubrication
System, power generating ratio switches blower fan number of times, extends the working life of blower fan.
The utility model realizes with following technological scheme: a kind of Lodz external fan lubrication system, comprise fuel tank, oil pump and emergency bearing oil pump, fuel tank connects the oil inlet end of Lodz blower fan lubrication system by oil inlet pipe, and fuel tank connects the oil outlet end of Lodz blower fan lubrication system by oil outlet tube; Oil pump is all communicated with fuel tank with the inlet line of emergency bearing oil pump, and oil pump is all communicated with oil inlet pipe with the drain line of emergency bearing oil pump, the drain line of oil pump and emergency bearing oil pump is all provided with valve, oil inlet pipe is provided with pressure gauge.
Described valve is manually-operated gate.
Described pressure gauge adopts pressure gauge with electric contact, and pressure gauge with electric contact is connected with warning light.
Described pressure gauge adopts electronic pressure meter, and described valve adopts solenoid valve; The input end of described electronic pressure list catenation one controller, the output terminal connected electromagnetic valve of controller.
The beneficial effects of the utility model are: by this external lubrication system; use the shutdown do not occurred so far because lubrication system fault produces; extend the working life of Lodz blower fan; the disorderly closedown number of times (except annual overhaul) decreasing Lodz blower fan clearly; greatly reduce plant maintenance amount, provide reliable guarantee to the safe operation of whole coal gas system.
Accompanying drawing explanation
Fig. 1 is the utility model theory diagram.
In figure: 1, oil inlet pipe, 2, oil outlet tube, 3, oil pump, 4, emergency bearing oil pump, 5, fuel tank, 6, pressure gauge, 7, valve.
Embodiment
As shown in Figure 1, a kind of Lodz external fan lubrication system has a fuel tank 5, oil pump 3 and emergency bearing oil pump 4, and fuel tank 5 connects the oil inlet end of Lodz blower fan lubrication system by oil inlet pipe 1, and fuel tank 5 connects the oil outlet end of Lodz blower fan lubrication system by oil outlet tube 2; Oil pump 3 is all communicated with fuel tank 5 with the inlet line of emergency bearing oil pump 4, and oil pump 3 is all communicated with oil inlet pipe 1 with the drain line of emergency bearing oil pump 4, and the drain line of oil pump 3 and emergency bearing oil pump 4 is all provided with valve 7, oil inlet pipe is provided with pressure gauge 6.
Embodiment 1
Valve 7 is manually-operated gate, and pressure gauge 6 adopts pressure gauge with electric contact, and pressure gauge with electric contact is connected with warning light.Electric contact pressure is arranged on working site, facilitates field personnel to check; Warning light is arranged on operating room, facilitates administrative staff to understand field condition in time.
Embodiment 2
Pressure gauge 6 adopts electronic pressure meter, and valve 7 adopts solenoid valve; The input end of electronic pressure list catenation one controller, the output terminal connected electromagnetic valve of controller, the input end of controller is connected with warning light.
Working procedure: for embodiment 2, the oil pump in fuel tank 5 is entered the internal lubricating system of Lodz blower fan by oil pump 3 by oil inlet pipe 1, the oil that Lodz blower interior is unnecessary in addition flows back to fuel tank by oil outlet tube.Electronic pressure meter shows the pressure of fuel tank in real time, pressure signal is delivered to controller process to judge simultaneously, when oil pump 3 breaks down, the pressure of in-line reduces, closed electromagnetic valve in controller control oil pump 3 outlet line, closes oil pump 3, starts emergency bearing oil pump 4 simultaneously, open the solenoid valve on emergency bearing oil pump 4 drain line, ensure system worked well.
The utility model (embodiment 2) is compared with existing Lodz blower fan has following features:
1, by external for the lubricating pump of Lodz blower fan, lubrication system is independent, adopt independent pumping plant to carry out lubrication oil supply to Lodz blower fan, and install emergency bearing oil pump additional.
2, oil pressure display uses electronic pressure meter, the form of fuel injection pressure signal warning light is passed to operating room so that the real-time oil pressure observing lubrication system of operator.
3, as occur oil pump damage low fuel pressure, by electrical system timely automatic switchover emergency bearing oil pump feed lubrication is carried out to body, achieve the uninterrupted fuel feeding of lubrication system.
4, external for lubricating pump pumping plant, the turbidity test of lubricating oil product can also be found timely, as dirtyly in oil product clearly can filter work at external fuel tank to lubricant oil by oil filter when not blowing-out machine by external fuel tank, or change oil, the clean of oil product can be ensured.
