Abstract
The utility model discloses a kind of operator guards preventing air compressor high-temperature damage; it comprises motor (1), air compressor host (2) is provided with temperature transducer (3) in the outlet of air compressor host (2); temperature transducer (3) with can monitor the supervisory device of assigned temperature value with warming velocity (4) and be connected, supervisory device (4) is connected with the start stop apparatus of motor (1).When main exhaust mouth temperature reaches more than 50 DEG C, and when the speed that temperature raises reaches limit value, unit emergency shutdown, and the failure warning reporting " temperature rise is too fast ".Can combine with overtemperature prote like this, opening when air compressor host exhaust port temperatures reaches 50 DEG C just can starting protection function, thus can well avoid high temperature to the damage of air compressor, and the required precision of this structure to temperature transducer is lower.
Description
Technical field
The utility model relates to a kind of operator guards preventing air compressor high-temperature damage, belongs to air compressor and manufactures field.
Background technique
Air compressor is the device mechanical energy of motor being converted to gas pressure energy, is compressed-air actuated pressure generator, is all widely used in every field.Air compressor can produce amount of heat in the process run.When air compressor host generation exception or compressor oil starvation, the gas temperature of discharging from air compressor host can raise rapidly, finally burns main frame.For protection air compressor normally runs; the method of existing protected host is the temperature of monitoring air compressor host relief opening; when temperature reaches warning or shuts down setting value, unit meeting automatic alarm also urgent autostop, to protect air compressor host (abbreviation overtemperature prote).One of defect of this method is: only temperature reach very high-temperature time just work, and some component of air compressor have likely caused injury to a certain degree; Two of defect is: all require higher to the precision of monitoring temperature instrument and reliability.
Summary of the invention
The technical problems to be solved in the utility model is to provide one can more early judge air compressor fault, can prevent the operator guards of air compressor high-temperature damage, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: the operator guards that can prevent air compressor high-temperature damage; it comprises motor, air compressor host; temperature transducer is provided with in the outlet of air compressor host; temperature transducer with can monitor assigned temperature value and be connected with the supervisory device of warming velocity, supervisory device is connected with the start stop apparatus of motor.
Described supervisory device is single-chip microcomputer.
Compared with the prior art, the utility model is at air compressor host relief opening mounting temperature sensor, temperature transducer with can monitor assigned temperature value and be connected with the supervisory device of warming velocity, after such air compressor startup optimization, temperature transducer detects the main exhaust mouth temperature of air compressor, and real time data is sent to supervisory device.When supervisory device detects that main exhaust mouth temperature reaches more than 50 DEG C; and the speed that temperature raises is when reaching limit value; send the failure warning of relative alarm " temperature rise is too fast "; and make unit emergency shutdown; can combine with overtemperature prote like this; opening when air compressor host exhaust port temperatures reaches 50 DEG C just can starting protection function, thus can well avoid high temperature to the damage of air compressor, and the required precision of this structure to temperature transducer is lower.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the resolution principle figure of supervisory device in the utility model.
embodiment:
Embodiment: as shown in Figure 1, the main body of air compressor is motor 1 and air compressor host 2, temperature transducer 3 is provided with in the outlet of air compressor host 2, the temperature signal that temperature transducer 3 collects by telecommunication cable with can monitor assigned temperature value and be connected with the supervisory device 4 of warming velocity, its assigned temperature is 50 DEG C, then think when the monitoring of warming velocity refers to that range of temperature is 10 DEG C in 5 seconds that warming velocity is too fast, send relative alarm, concrete judgement is as Fig. 2, the supervisory device 4 that can realize above-mentioned functions can be existing conventional single-chip microcomputer, supervisory device 4 is connected with the start stop apparatus of motor 1, when the halt condition of satisfied setting, single-chip microcomputer sends stopping signal.
Claims (2)
1. one kind can prevent the operator guards of air compressor high-temperature damage; it comprises motor (1), air compressor host (2); it is characterized in that: be provided with temperature transducer (3) in the outlet of air compressor host (2); temperature transducer (3) with can monitor the supervisory device of assigned temperature value with warming velocity (4) and be connected, supervisory device (4) is connected with the start stop apparatus of motor (1).
2. the operator guards preventing air compressor high-temperature damage according to claim 1, is characterized in that: described supervisory device (4) is single-chip microcomputer.
