Abstract
The utility model relates to the field of industrial automation, in particular to a device for online monitoring the running of a fan. The device is provided with a fan. The device is characterized by comprising a fan power supply circuit; the fan is connected in series with the fan power supply circuit; the fan power supply circuit is provided with a stop output, a jamming output and a common end; the stop output and the jamming output are normally-opened ends; the common end is a normally-closed end; and the stop output, the jamming output and the public end are connected with a protective device respectively. By adopting the structure, the running state of the industrial fan can be monitored exactly, the exact running state signal can be provided, and the fan which is not provided with a thermal protection function can be protected effectively against the destroy resulting from jamming.
Description
Technical field
The utility model relates to the industrial automation field, specifically a kind of online fan operation monitoring device that the industrial fan running state is carried out online detection.
Background technique
At present, the surveillance style of general-purpose industrial fan operation state is, a blast switch is installed at the fan outlet place, this inductive switching blower fan blast pressure action, running state to control system feedback industrial fan, its deficiency is: 1, because the quality and the life problems of work under bad environment, switching device exist the switching element action unreliable, may cause running state information inaccurate; 2, this monitoring technology adopts off-line switch monitoring mode; can only monitor the running state of fan operation/not; situation to the blower fan stall that causes for some reason; can't accurately monitor; because there is above-mentioned deficiency in this monitoring technology, judgement, blower fan maintenance and protection to the fan operation fault during use have increased difficulty.
Summary of the invention
In order to overcome the deficiency of existing industrial fan operation monitoring technology,, fan operation provide more definite information, the purpose of this utility model to be to provide a kind of novel industrial fan in-service monitoring device for monitoring, safeguard and protect.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of online fan operation monitoring device; be provided with blower fan; it is characterized in that being provided with the blower fan current supply circuit; blower fan is series at the blower fan current supply circuit; the blower fan current supply circuit is provided with stall output, stall output and common port; stall output, stall are output as Chang Kaiduan; common port is a normal-closed end; stall output, stall output are connected with protective gear respectively with common port; electric current with induction blower fan circuit changes; can monitor the running state of industrial fan definitely, provide definite fault message during the fan operation fault.
The utility model can accurately be monitored the running state of industrial fan owing to adopt said structure, provides definite operating state signal; For the blower fan that does not have heat protection function, can effectively protect blower fan can be because of stall former thereby damage.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Reference character: blower fan 1, blower fan current supply circuit 2, stall output 3, stall output 4, common port 5.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in drawings; a kind of online fan operation monitoring device; be provided with blower fan 1; it is characterized in that being provided with blower fan current supply circuit 2; blower fan 1 is series at blower fan current supply circuit 2; blower fan current supply circuit 2 is provided with stall output 3, stall output 4 and common port 5; stall output 3, stall output 4 are Chang Kaiduan; common port 5 is a normal-closed end; stall output 3, stall output 4 are connected with protective gear respectively with common port 5; electric current with induction blower fan circuit changes, and can monitor the running state of industrial fan definitely, provides definite fault message during the fan operation fault.
The utility model can accurately be monitored the running state of industrial fan owing to adopt said structure, provides definite operating state signal; For the blower fan that does not have heat protection function, can effectively protect blower fan can be because of stall former thereby damage.
