Abstract
The utility model relates to a combustion fan field especially relates to a temperature control device of fan motor bearing, including temperature element and electromagnetic flowmeter, its characterized in that, temperature element and electromagnetic flowmeter do not link to each other with programmable controller's input module through twisted pair cable, and programmable controller's analog output module links to each other with human-computer interface, and programmable controller's switching value output module links to each other with alarm indicator. The temperature measuring element is a thermocouple PT 100. Compared with the prior art, the beneficial effects of the utility model are that: the trend of rapid remote monitoring of temperature and air volume change is realized, and the accuracy and reliability of control are greatly improved; meanwhile, once the temperature of the bearing exceeds the limit, an operator can check and confirm the bearing in the first time, so that the stable operation of a combustion fan motor and a heating furnace is ensured, and the occurrence of serious equipment damage accidents is avoided.
Description
Technical field
The utility model relates to combustion fan field, relates in particular to a kind of temperature control equipment of blower motor bearing.
Background technology
Combustion fan is the key equipment of the unique long-term continuous operation in heating furnace process of burning steel, it is driven by the alternating current generator of a 400KW, if damaging, motor bearings causes scaling loss, changing this motor needs more than 36 hours, cause serious equipment breakdown, what impact was produced carries out smoothly, therefore guarantee that this motor stabilizing work just seems particularly important, in motor manufacture process, in motor shaft socket end orifice, detector unit has been installed, for detection of the temperature of motor bearings, at air door of fan entrance, the electromagnetic flowmeter element that air volume test is used has been installed.But in the long-term continuous operation process of blower motor, discovery is due to cannot directly monitoring motor bearings temperature and air quantity curve and correlationship, the rate of temperature change relation that causes operating personnel cannot observe motor bearings when changing fan delivery, when air quantity rate of change is excessive, motor bearings temperature sharply rises and presents vicious cycle, and in a few minutes, motor will scaling loss catch fire.
Summary of the invention
The purpose of this utility model is to provide a kind of temperature control equipment of blower motor bearing, monitors in real time motor bearings temperature and air quantity curvilinear trend state, accuracy and the reliability of to improve operator, adjusting fan delivery; Once while temperature over-range, alarm lamp flicker on operator's console, operating personnel can check confirmation in the very first time, guarantee the stable operation of blower motor and heating furnace, avoid serious device damage accident to occur.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of temperature control equipment of blower motor bearing, comprise temperature element and electromagnetic flowmeter, described temperature element is connected with the load module of programmable controller through pair cable respectively with electromagnetic flowmeter, the analog output module of programmable controller is connected with man-machine interface, and the switching value output module of programmable controller is connected with alarm lamp.
Described temperature element is thermopair PT100.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, easy to operate, practical, realized the variation tendency of quick remote monitoring temperature and air quantity, and improved widely accuracy and reliability that operator adjusts fan delivery; Once excessive bearing temperature simultaneously, alarm lamp flicker on operator's console, operating personnel can check confirmation in the very first time, guaranteed the stable operation of combustion fan motor and heating furnace, have avoided the generation of serious device damage accident.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic block diagram.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1, it is the temperature control equipment example structure schematic diagram of a kind of blower motor bearing of the utility model, comprise temperature element and electromagnetic flowmeter, temperature element is arranged in blower motor bearing end orifice, temperature for detection of motor bearings, electromagnetic flowmeter is arranged on air door of fan porch, the signal that temperature element is sent with electromagnetic flowmeter is connected with the load module of programmable controller through pair cable respectively, the analog output module of programmable controller is connected with man-machine interface, the switching value output module of programmable controller is connected with the alarm lamp on operator's console.
Temperature element in embodiment is thermopair PT100, has good linearity, the advantage that precision is high.
Programmable controller is according to temperature signal and flow signal formation temperature and air quantity curvilinear trend curvilinear figure, and through connection, export man-machine interface to and show in real time, operator monitor motor bearings temperature and air quantity trend curve regulate, and have greatly improved accuracy and the reliability of operation.When excessive bearing temperature, alarm lamp flicker on operator's console, operating personnel can check confirmation in the very first time.
Claims (2)
