Large-scale rotating machine bearing temperature alarming and monitoring device

Abstract

The invention discloses a large-scale rotating machine bearing temperature alarming and monitoring device which comprises an alternating current power source, a fuse, an alarm light, a transformer, a rectifier, a first voltage stabilizer, a second voltage stabilizer, a voice frequency integrated chip, a temperature sensor, a first diode, a second diode, a light emitting diode, a first triode, a second triode, a third triode, an operational amplifier, a loudspeaker, a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a fifth capacitor, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a sixth resistor and a seventh resistor. The large-scale rotating machine bearing temperature alarming and monitoring device is simple in circuit structure, few in adopted elements, small in size, low in manufacturing cost and easy to manufacture, has voice monitoring and alarming and flicker alarming functions at the same time, is high in caution effect, and easily draws attention of a worker.

Description

technical field [0001] The invention relates to a large-scale rotating machinery monitoring device, in particular to a large-scale rotating machinery bearing temperature alarm monitoring device. Background technique [0002] The large-scale rotating machinery bearing temperature alarm monitoring device in the prior art has complex circuit structure, many components, bulky volume, high production cost and is not easy to manufacture, especially when the large-scale rotating machinery rotates too fast, the temperature of the bearing will rise , The bearing temperature exceeds the allowable value, which is easy to cause damage to the equipment. The large-scale rotating machinery bearing temperature alarm monitoring device in the prior art monitors and alarms the bearing overheating, either only has an audible alarm, or only has a flashing alarm, and the warning effect of such a monitoring and alarm device is not strong. Contents of the invention [0003] The object of the pre...
