The gear box thin oil lubricating alarming control device comprises a gear box and a motor matched with the gear box, the gear box is provided with an oil inlet and an oil outlet, the oil inlet and the oil outlet of the gear box are connected with an oil pipe, the oil pipe is connected with a thin oil pump, a pressure sensor capable of collecting thin oil pressure signals is mounted at the position, close to the oil inlet of the gear box, on the oil pipe, the pressure sensor is connected with a programmable logic controller, the programmable logic controller is connected with the motor and an alarming flicker light, and the programmable logic controller can control the motor matched with the gear box and the alarming flicker light after comparing the collected thin oil pressure signals and a set thin oil pressure value. The gear box thin oil lubricating alarming control device can reduce the situation that gears and bearings are damaged due to oil shortage in the gear box and improve production efficiency.
Description
Technical field
The utility model belongs to hotrolling seamless pipe unit apparatus technical field, relates in particular to a kind of gear-box thin oil lubricant alarm control unit.
Background technique
At present, in the existing hotrolling seamless pipe unit of our factory, big and small gear-box is a lot, and large gear-box all needs to have independent thin oil pump to be lubricated to gear and the bearing of gear-box conventionally, prevents that gear from destroying, bearing burnt; And at present gear-box have there is no oil, whether oil outlet stops up and whether the each parts of gear-box the problem such as obtain lubricating and all need to confirm manually, but because a variety of causes (gear-box leakage of oil causes thin oil minimizing, thin oil pump not to show oil, the obstruction of thin oil oil outlet etc. without pressure) causes gear-box oil starvation, and then gear in gear-box is destroyed, the situation of bearing burnt still once and again again and three generation, impact is produced, and reduces manufacturing efficiency.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, provides a kind of gear-box that reduces to occur because oil starvation causes the situation of gear and bearing damage, the gear-box thin oil lubricant alarm control unit of enhancing productivity, and its technological scheme is as follows:
A kind of gear-box thin oil lubricant alarm control unit, comprise gear-box and with the supporting motor of gear-box, gear-box is provided with filler opening and oil outlet, it is characterized in that, filler opening and the oil outlet of described gear-box are connected with oil pipe, on oil pipe, be connected with thin oil pump, on oil pipe, be positioned near the filler opening place of gear-box the pressure transducer that can gather thin oil pressure signal is installed, pressure transducer is connected with programmable controller, programmable controller is connected with motor and warning flashing lamp, programmable controller is controlled motor and the warning flashing lamp supporting with gear-box after can comparing by the thin oil force value of the thin oil pressure signal of collection and setting.
Optimal way is that described pressure transducer is connected with programmable controller by four-core shielded cable.
The gear-box thin oil lubricant alarm control unit that the utility model provides, at the filler opening place near gear-box, a pressure transducer is installed, the pressure signal that pressure transducer is collected is sent to on-the-spot programmable controller (to be called for short: PLC), PLC utilizes programming software to carry out calculation process collecting pressure signal, arranges three control point values (thin oil pressure is high, thin oil pressure is low and thin oil pressure normal) the supporting motor of gear-box is controlled by PLC programming; Motor will start, and need to meet supporting gear-box thin oil pressure be at normal state, and motor is in running, if PLC detects when the low or pressure of thin oil pressure is high, the oil lubricating system that gear-box is described has gone wrong, PLC is output alarm signal immediately, start the warning flashing lamp of thin oil lubricant, remind on-the-spot operator's gear-box thin oil extremely to need to check, stop machine operation simultaneously.In process of production, as long as thin oil pressure is undesired, motor just stops automatically, starting electrical machinery again after the thin oils such as need are normal, avoid gear-box also to work on and cause gear to be destroyed and the situation of bearing burnt occurs because lacking thin oil, reduce equipment failure, enhance productivity.Further; pressure transducer is connected with programmable controller by four-core shielded cable; utilizing shielded cable is anti-tampering effect; improve the stability of data capture; be convenient to the signal that controller gathers pressure transducer; thereby the startup that realization is controlled motor by the pressure of system stops, the protection gear of gear-box and the life-span of bearing.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Illustrate embodiment below in conjunction with Fig. 1:
As shown in Figure 1, a kind of gear-box thin oil lubricant alarm control unit, comprise gear-box 1 and with the supporting motor 2 of gear-box 1, gear-box 1 is provided with filler opening 3 and oil outlet 4, filler opening 3 and the oil outlet 4 of described gear-box 1 are connected with oil pipe 5, on oil pipe 5, be connected with thin oil pump 6, on oil pipe 5, be positioned near the filler opening 3 front end 5cm places of gear-box 1 pressure transducer 7 that can gather thin oil pressure signal is installed, when setting pressure sensor 7, the tapping of punching on the oil pipe 5 of thin oil, installs pressure transducer 7.Pressure transducer 7 is connected with programmable controller 8, programmable controller is Siemens S7-300 controller, programmable controller 8 is connected with motor 2 and warning flashing lamp 9, and programmable controller 8 is controlled motor 2 and the warning flashing lamp 9 supporting with gear-box 1 after can comparing by the thin oil force value of the thin oil pressure signal of collection and setting.Described pressure transducer 7 is connected with programmable controller 8 by four-core shielded cable 10.
Process control device and the technology of the utility model design, in process of production, as long as thin oil pressure is undesired, motor just stops automatically, starting electrical machinery again after the thin oils such as need are normal, avoid gear-box also to work on and cause gear to be destroyed and the situation of bearing burnt occurs because lacking thin oil, reduce equipment failure, enhance productivity.
