Abstract
The invention discloses a bearing bush lubrication system and relates to the technical field of wood processing. The bearing bush lubrication system comprises a main motor bearing bush lubrication oil way. A power unit of the main motor bearing bush lubrication oil way is controlled by a main loop and a control loop. The main motor bearing bush lubrication oil way is composed of the power unit, a main motor front bearing bush, a main motor back bearing bush, an oil tank and pipelines. A high-level oil tank is further arranged in the main motor bearing bush lubrication oil way and located above the main motor front bearing bush and the main motor back bearing bush. An oil inlet of the high-level oil tank communicates with an oil outlet of the power unit. An oil outlet of the high-level oil tank communicates with an oil inlet of the main motor front bearing bush and an oil inlet of the main motor back bearing bush through the pipelines. An oil return opening of the main motor front bearing bush and an oil return opening of the main motor back bearing bush communicate with the oil tank through the pipelines. According to the bearing bush lubrication system, the problems that the bearing bush lubrication system cannot supply oil, and the main motor bearing bushes are burnt due to the fact that a man-made fiberboard production line hot grinding main motor circuit loses power accidentally can be solved.
Description
Technical field
The present invention relates to medium-density fiberboard production line manufacturing technology field, especially a kind of fibreboard production line defibrator process mair motor bearing shell lubricating system.
Background technology
At present, the wood processing enterprise many employings production line producing middle and higher density fibre board produces continuously, nucleus equipment in whole production line is defibrator system, the mair motor providing major impetus for defibrator is the threephase asynchronous typically using 10KV three-phase Wound-rotor type, power of motor is 3550KW, owing to this main motor current is bigger, its bearing shell lubricating requirement is the highest, therefore this motor bearing lubrication uses single a set of lubricating system, Fig. 1 is that mair motor controls electrical schematic diagram, this motor bearing lubricant passage way sketch of Fig. 2；As shown in Figure 1, in figure, dotted line upper part is that the main power source of motor is controlled by defibrator PLC, dotted line lower part is motor bearing lubricating system field control, bearing shell lubricating system is first started before starting mair motor, first QS1 on and off switch closes a floodgate, the CPU main control line road catalyst KM Guan Bi of defibrator PLC provides power to bearing shell lubricating system, then operator close a floodgate QS2 on and off switch to on-site manual, again by manually starting the first Oil pump electrical machinery or the second Oil pump electrical machinery to motor bearing feed lubrication by start button SB1 or SB2, finally start mair motor；When the pressure in oil passage is less than setting value, then the second oil pump automatically engages and makes for ensureing fuel delivery; in addition; pressure-detecting device and temperature-detecting device are installed on oil circuit; its signal feeds back to the CPU of defibrator PLC; if hypotony or too high, lubricating oil temperature is too high, stop mair motor and protect motor, in order to avoid damage bearing shell because few oil, oil starvation or oil temperature are too high or burn mair motor；This Lubrication Control System has following defects that 1) due to lubricating system main power source by defibrator PLC CPU main control line road catalyst KM close provide, cause main line catalyst KM separately when main line catalyst KM controls to go wrong, whole bearing shell lubricating system power-off is thus caused to quit work, mair motor will be low because of oil pressure or bearing bush temperature is high quits work, and the most not only motor bearing can be made to be worn but also affect the seriality of production；2) do not controlled by the CPU of defibrator PLC owing to lubricating system starts, on-site manual need to be arrived and start the first Oil pump electrical machinery by start button SB1 or SB2 or the second Oil pump electrical machinery comes to mair motor bearing shell feed lubrication, outside cause such as external power source has a power failure suddenly and restores electricity at once or the lightning etc. that thunders causes supply voltage moment to decline, whole control system is quit work, if now mair motor circuit breaker internal control parts such as switching winding burns, separating brake controls that supply voltage is too low or brake separating mechanism mechanical part the reason such as blocks and causes the chopper can not normal separating brake, so mair motor will continue to run with under not having lubrication circumstances, its consequence is exactly that mair motor bearing shell burns out or mair motor burns；3) mair motor is under normal operating conditions, suddenly power supply is lost if as outside cause, could stop completely owing to inertia reason mair motor also may proceed to run about 5 minutes, owing to there is no power supply in during this period of time, lubricating system cannot be run, mean what mair motor ran in the case of not having lubricating oil, mair motor bearing shell oil-free thus can be made to wear and tear, motor bearing seriously can be caused to damage or even mair motor burns.Mair motor bearing shell lubricant passage way as shown in Figure 2, lubricating oil enters directly into front bearing shell 1 and the rear bearing shell 2 of mair motor from fuel tank, then returns to fuel tank through oil return pipe；The defect of this lubricant passage way is: when bearing shell lubricating system dead electricity, the first Oil pump electrical machinery or the second Oil pump electrical machinery quit work, and mair motor bearing shell can not get oil lubrication, is likely to result in mair motor bearing bush abrasion or the situation generation burnt out.
Summary of the invention
It is an object of the invention to provide a kind of bearing shell lubricating system, it can solve staple fibre board assembly line defibrator process mair motor circuit accident dead electricity and cause the bearing shell lubricating system cannot the fuel feeding problem of burning mair motor bearing shell.
In order to solve the problems referred to above, the technical solution adopted in the present invention is:
This bearing shell lubricating system, including mair motor bearing shell lubricant passage way, the power unit of described mair motor bearing shell lubricant passage way is by major loop and controls circuit controls；Described mair motor bearing shell lubricant passage way is by power unit, bearing shell before mair motor, bearing shell after mair motor, fuel tank and pipeline composition, described mair motor bearing shell lubricant passage way is additionally provided with a top petrol tank, described top petrol tank is positioned at before described mair motor the top of bearing shell after bearing shell and described mair motor, the oil-in of described top petrol tank connects with the oil-out of described power unit, the oil-out of described top petrol tank is connected by the oil-in of pipeline bearing shell front with described mair motor and rear bearing shell, the front bearing shell of described mair motor is connected with described fuel tank by pipeline with the oil return opening of rear bearing shell.
In technique scheme, more specifically technical scheme is it may also is that described major loop is made up of the first start button, major loop catalyst, the second start button, the first Oil pump electrical machinery and the second Oil pump electrical machinery；Described control loop is controlled by the first catalyst, the time relay and the second catalyst, and wherein the first contacts of contactor controls the first Oil pump electrical machinery, and the second contacts of contactor controls the second Oil pump electrical machinery；Described first contactor coil constitutes first point of loop；Described first catalyst normally-closed contact constitutes second point of loop with the described time relay；Described second contactor coil and described time relay delayed contact constitute the 3rd point of loop；Described first point of loop, described second point of loop and described 3rd point of loop compose in parallel described control loop.
