Abstract
The utility model discloses an electric furnace cooling control system which comprises a controller, water pump working condition detecting units, a water pressure sensor and an alarm device, wherein the water pump working condition detecting units are respectively arranged in a working water pump and a standby water pump and are used for transmitting water pump working condition detecting signals to the controller; the water pressure sensor is arranged at the tail end of a cooling system pipeline and is used for transmitting water pressure detecting signals to the controller; and the controller is used for transmitting control signals to the working water pump, the standby water pump and the alarm device. An automatic control and alarm system can be used for effectively switching in time so as to close the fault water pump, open the standby water pump and warn, so that workers can overhaul in time; and the electric furnace cooling control system is capable of reflecting the working condition of the water pump in real time, so that the safety of the production work is guaranteed, and the economic loss caused by equipment failure can be reduced.
Description
Technical field
The utility model relates to electric furnace cooling control system, in particular, is a kind of switched system of cooling water pump.
Background technology
Main frequency furnace in use; The water cooling system of water jacket and coil is cannot be out-of-work, and present cooling device adopts two water pumps, and one of a job is subsequent use; When the work water pump breaks down, satisfy the supply of cooling water through manual switching and external water tank.But in the application of reality, because the fault of water pump is not in time switched, the equipment damage and the security incident that cause emerge in an endless stream, and therefore the mode of this manual switching water pump can not satisfy the needs of safety in production.
The utility model content
The utility model technical problem to be solved is that realization is a kind of when the work water pump breaks down, the control system of switching voluntarily.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of electric furnace cooling control system; Comprise controller, pump operating condition detecting unit, hydraulic pressure sensor and alarm; Described pump operating condition detecting unit is arranged in work water pump and the reserve pump and with the pump operating condition detection signal and is delivered to controller; Described hydraulic pressure sensor is arranged at cooling system pipeline end and the hydraulic pressure detection signal is delivered to controller, and described controller outputs control signals to work water pump, reserve pump and alarm.
Described controller also is provided with display unit, pump operating condition signal data and hydraulic signal data that described display unit display controller receives.
Described alarm is provided with alarm lamp and emergency alarm bell.
The advantage of the utility model is to control automatically and warning system can be switched timely and effectively; Close the fault water pump and open reserve pump; And warn, let the staff in time overhaul, and this system reflect the pump working situation in real time; Make the safety of production work that guarantee arranged, reduced the economic loss that equipment fault causes.
Description of drawings
Facing the content of every width of cloth accompanying drawing expression in the utility model specification and the mark among the figure down briefly explains:
Fig. 1 is an electric furnace cooling control system theory diagram
Mark among the above-mentioned figure is: 1, controller; 2, work water pump; 3, reserve pump; 4, hydraulic pressure sensor; 5, alarm; 6, pump operating condition detecting unit.
The specific embodiment
Can know that referring to Fig. 1 this control system mainly comprises controller 1, pump operating condition detecting unit 6, hydraulic pressure sensor 4, alarm 5 and display unit.Wherein pump operating condition detecting unit 6 is mainly gathered signals such as pump rotary speeds, operating voltage; Thereby judge by controller 1 whether water pump is in normal operating conditions; Pump operating condition detecting unit 6 is provided with two; Be arranged at respectively in work water pump 2 and the reserve pump 3, whether the water pump that detects in work exists unusually these signal conveys to the controller 1 that pump operating condition detecting unit 6 will be gathered.Be provided with hydraulic pressure sensor 4 at cooling system pipeline end, this sensor 4 is delivered to controller 1 with the pump water delivery port place hydraulic signal value that detects.Controller 1 after receiving the signal that above-mentioned pump operating condition detecting unit 6 and hydraulic pressure sensor 4 carry with deposit the interval numerical value of water pump operate as normal and compare; If judge the normal display unit that then the data demonstration extremely is connected with controller 1; If exceed normal interval value, work water pump 2 is in abnormality, then closes work water pump 2; Open reserve pump 3; And send alarm signal to the alarm 5 that is connected with controller 1 by controller 1, and send caution by alarm 5 to the staff, simultaneously abnormal data is shown in display unit.The pump operating condition signal data and the hydraulic signal data that receive of the main display controller of display unit 1 wherein; The staff can be through the duty of these data in real time monitoring water pumps; Contingent fault is made judgement in advance, also can carry out accident analysis the water pump that has broken down.Wherein alarm 5 through sound and high light, sends dual caution to the staff by alarm lamp and emergency alarm bell.
To sum up, this control system switches automatically when water pump is in abnormality and warns the staff, has effectively avoided failing in time to switch water pump and the hidden danger that causes.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
