Abstract
The utility model belongs to pulverizer lubricate station circuit protection field, discloses a kind of pulverizer lubricate station circuit control device.By self-holding circuit contactor is pulled down with the terminal that the terminal of contactor is connected on the spot, skip distant place change-over switch on the spot, directly receive on air switch., can there is not again the phenomenon of the pump tripping operation that produces because of the problem of knob in pulverizer lubricate station circuit control device of the present utility model; Because of site examining and repairing job requirement, sometimes need to switch distant place state on the spot, now can there is not trip phenomenon yet; While having pump operation, a distant place switches on the spot or switches on the spot a distant place, also can not control power supply moment to lose, and causes the phenomenon of process pump power failure tripping.
Description
[technical field]
The utility model relates to pulverizer lubricate station circuit protection field, specifically a kind of pulverizer lubricate station circuit control device.
[background technology]
Pulverizer lubricate station is mainly used to guarantee the normal start-stop of mill and protects mill to work under normal environment.The protection of the oil pump of mill petrol station, electrical heating, each measuring sensor and interlocking are realized by the DCS of unit, and secondary circuit is realized in petrol station local control box.A permission distant place and on the spot 2 kinds of Starting mode.Pulverizer lubricate station oil pump and electrically heated start and stop are all short instructions in the distance and on the spot, and this just requires must there be self-holding circuit in loop, avoid pump only to start just tripping operation.The self-holding circuit of pulverizer lubricate station is connected on a distant place on the spot after knob, in the distance or be all normal with regard to underground activities.But when having in pump operation, when a distant place switches on the spot or switches to a distant place on the spot, will cause controlling power supply moment to lose, cause process pump power failure tripping.When on on-site control, change-over switch knob base is loosening on the spot in a distant place, a distant place can be lost with regard to earth signal, also can cause to control power supply moment and lose, and causes process pump power failure tripping, is difficult to the localization of faults when problems checks.
[summary of the invention]
In view of above problem, the utility model provides a kind of pulverizer lubricate station circuit control device.The technical solution of the utility model is by self-holding circuit contactor being pulled down with the terminal that the terminal of contactor is connected on the spot, skipped distant place change-over switch on the spot, directly receiving on air switch.
The utility model provides a kind of pulverizer lubricate station circuit control device, comprise power supply 1, air switch 13, switch 72 on the spot, distant place switch 82, a distant place is change-over switch 2 on the spot, contactor 3 on the spot, distant place contactor 6, pump 93 on the spot, distant place pump 96, start button 4 on the spot, distant place start button 7, and self-holding circuit contactor 5, power supply 1 connects air switch 13, air switch 13 connects distant place change-over switch 2 on the spot, switch 72 connects contactor 3 and on the spot pump 93 on the spot on the spot, distant place switch 82 connects distant place contactor 6 and distant place pump 96, contactor 3 connects start button 4 on the spot on the spot, distant place contactor 6 connects distant place start button 7, one end of self-holding circuit contactor 5 connects start button 4 and distant place start button 7 on the spot, it is characterized in that: the other end of self-holding circuit contactor 5 directly connects air switch 13.
The utlity model has following beneficial effect: pulverizer lubricate station circuit control device of the present utility model, the phenomenon of the pump tripping operation that produces because of the problem of knob can not occur again; Because of site examining and repairing job requirement, sometimes need to switch distant place state on the spot, now can there is not trip phenomenon yet; While having pump operation, a distant place switches on the spot or switches on the spot a distant place, also can not control power supply moment to lose, and causes the phenomenon of process pump power failure tripping.
