Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, for the structured flowchart of the liquid level of the utility model embodiment protection warning device, be example with the glycol circulation system, liquid level protection warning device of the present utility model is used for the liquid level protection of glycol circulation system.This liquid level protection warning device is mainly by controller 3; audible-visual annunciator 4; liquid level sensor 2 and host computer 6 constitute; can set the working method of fluid circulation system 1 by host computer 6; choice of circulating pumps and liquid level are set in the fluid circulation system 1; the working method of fluid circulation system 1 comprises manually and automatic two kinds; be provided with two water circulating pumps in the fluid circulation system 1; No. 1 water pump 8 and No. 2 water pumps 9; two water circulating pumps one are equipped with a usefulness; the liquid level that host computer 6 sets comprises the setting of standard liquid level; liquid level forward scope is set and the reverse scope of liquid level is set, and host computer 6 also has current liquid level Presentation Function simultaneously.The liquid level of host computer 6 is set and is specially:
The standard liquid level is set: the normal level value that is used for setting fluid circulation system 1 operation.
Liquid level forward scope: be used for being set in and allow the level value that exceeds on the basis of standard liquid level, current level value during less than standard liquid level and liquid level forward scope sum system think normally, when current level value was higher than standard liquid level and liquid level forward scope sum, system reported to the police the high limit.
The reverse scope of liquid level: be used for being set in and allow the level value that reduces on the basis of standard liquid level, system was thought normally when current level value was higher than the difference of standard liquid level and the reverse scope of liquid level, when current level value was lower than the difference of standard liquid level and the reverse scope of liquid level, system reported to the police lower bound.
Between controller 3 and host computer 6, also be provided with data acquisition server 5, be used for data acquisition and transmission between controller 3 and the host computer 6.Controller 3 also is connected with switch board 7, and this switch board 7 is preferably is permitted the switch board that continues, and is used for the conversion of the manual and automatic working method of the controlling liquid circulation system 1.
As shown in Figure 2, protect the fluid circulation system workflow diagram of warning device for the liquid level that is provided with the utility model embodiment.
At first, system is carried out the selection of Local or Remote work.When being chosen as local operation, directly carry out function selecting, according to the situation of liquid level water circulating pump is controlled, when being chosen as operated from a distance, need further the working method of the circulation system to be selected.
When system is in manual operation, can start and stop any one water circulating pump at host computer 6 according to liquid level condition; When system is in automatic operation, the startup that system finishes water circulating pump according to level condition automatically stops and reporting to the police, when the switching of carrying out two water circulating pumps was selected, the control knob of the switch board that needs to guarantee to be permitted to continue was chosen in remote status, otherwise can't finish switching.Liquid level sensor 2 sends the level value of the fluid circulation system 1 gathered to controller 3 with the current signal of 4-20ma, parameter value according to the liquid level setting, when current level value during greater than system standard level value and liquid level forward scope sum, system carries out sound and light alarm after delaying time through one minute, and this moment, water circulating pump did not carry out any action; When current level value during less than the difference of system standard liquid level and the reverse scope of liquid level, systematization is carried out sound and light alarm after delaying time through one minute, this moment, water circulating pump quit work, when system alarm, can stop sound and light alarm by the ann reset button of host computer, duty before ann reset reverted to automatically and reports to the police when system recovery was normal continues to finish next warning function.
In the present embodiment, when system breaks down, the water circulating pump switch is chosen the local manually control that realizes, then the switch board power supply is disconnected.
As can be seen from the above embodiments; the utility model embodiment is by adopting the situation of liquid level in the real-time monitoring liquid circulation system of liquid level sensor; after handling, sends via controller sound and light alarm; and return to installment state by the liquid level in the controller Control Circulation system; real-time guard warning effect be can play the liquid level in the circulation system, the loss of liquid and the damage of equipment avoided.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
