Background technique
In enterprise produces, pumping station additionally arranges standby as the power public affairs of each production process, it has very important effect aborning, therefore, each pump group is designed to a standby working method for N (N>1) more, when the pump of wherein any operation breaks down, by electric interlock, automatically start stand by pump, guarantee the reliability and stability that pumping station supplies water.
This electric interlock, from driving the electric control theory of the motor of water pump, is mainly that the run signal by testing motor disappears, and carrys out interlocked startup reserve pump.This can play good standby introjection to electrical failures such as the overload that drives the motor of water pump to occur in running, under-voltage, phase shortages.But when there is outlet valve and fall the mechanical failure of the water pumps such as air inlet in the water supply process equipment failures such as handle or off-axis, pump chamber itself, drive motor run signal is normal, there is situation in actual pressure of supply water and water supply flow, at this time stand by pump can't drop into automatically, this will affect the direct motion of pumping plant subsequent production line, even stops production.
Summary of the invention
In order to overcome above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of stand by pump group automatic throw-in equipment, the automatic input function of stand by pump group while both having retained the original electrical failure of pump group, the automatic input function of stand by pump group while having increased again the mechanical failure of water supply process equipment failure or water pump itself, guaranteed that pumping plant supplies water stable and reliable, for the direct motion of subsequent production line provides assurance.
For achieving the above object, the technological scheme that the utility model adopts is, a kind of stand by pump group automatic throw-in equipment, comprise control contactor and signal node that quantity is identical, all control contactors are all connected with controller with signal node, described controller is programmable controller PLC, and this device also comprises the Pressure testing table identical with control contactor quantity and flow detection table, and all Pressure testing tables are all connected with programmable controller PLC signal with flow detection table; During use, Pressure testing table and flow detection table are all installed on the pipeline between each pump discharge valve and user.
Programmable controller PLC comprises analog input module, switching input module and switching value output module; All Pressure testing table, flow detection tables are all connected with analog input module, and all control contactors are all connected with switching value output module, and all signal node are all connected with switching input module.
The utility model stand by pump group automatic throw-in equipment compared with prior art, has the following advantages:
By all control contactors, signal node, Pressure testing table and flow detection table are all connected with programmable controller PLC signal, during use, on the pipeline between each pump discharge valve and user, all setting pressure detects table and flow detection table, realize the detection of drive motor, outlet pressure, rate of discharge, the automatic input function of stand by pump group while both having retained the original electrical failure of pump group, the automatic input function of stand by pump group while having increased again the mechanical failure of water supply process equipment failure or water pump itself, has improved the stability that pumping plant supplies water.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Prior art electric interlock starts in stand by pump device automatically, comprise power supply, power supply, control contactor 5, drive motor 2, water pump 3, pump discharge valve 6 and go user's pipeline to be connected successively, signal node 4 is connected with control contactor 5, and water pump 3 is connected with pond 1.This device mainly carrys out interlocked startup reserve pump by detecting the run signal of drive motor 2.
As shown in Figure 1, the utility model stand by pump group automatic throw-in equipment, comprise control contactor 5 and signal node 4 that quantity is identical, all control contactors 5 are all connected with controller with signal node 4, described controller is programmable controller PLC9, this device also comprises the Pressure testing table 7 identical with control contactor quantity and flow detection table 8, and all Pressure testing tables 7 are all connected with programmable controller PLC9 signal with flow detection table 8; During use, Pressure testing table 7 and flow detection table 8 are all installed on the pipeline between each pump discharge valve 6 and user.
Programmable controller PLC9 comprises analog input module 10, switching input module 11 and switching value output module 12; All Pressure testing table 7, flow detection tables 8 are all connected with analog input module 10, realize the Real-time Collection of pressure, flux signal; All signal node 4 are all connected with switching input module 12, judge the running state of drive motor 2; All control contactors 5 are all connected with switching value output module 11, and the automatic control program designing according to this device by programmable controller PLC9 is controlled the open and close of control contactor 5, thus realize to drive motor 2 open, stop control.
The utility model device control program that stand by pump group automatically drops into of also need to programming in programmable controller PLC9, the signal node 4 that is drive motor 2 is 1 o'clock, if flow instrumentation 8 signal values after corresponding pump discharge valve 6 are less than the low limit value of flow, and when 7 signal values of the pressure instrumentation after pump discharge valve 6 are less than pressure low limit value, programmable controller PLC9 is from switching value output template 12 output drive signals 1, make control contactor 5 closures of the drive motor 2 of reserve pump 3, thereby start reserve pump 3.Meanwhile, programmable controller PLC9 is from switching value output template 12 output drive signals 0, and the control contactor 5 of the drive motor 2 of current water pump 3 is disconnected, thereby guarantees that current water pump 3 reliably shuts down.
The utility model device is before coming into operation, need to the pressure low limit of the control program in programmable controller PLC9, the low limit value of flow be tested and be determined, concrete grammar is: manually boot M1 water pump 3, after the required water supply flow of user, pressure are normal, manually stop M1 water pump 3, interval, after very short time, manually boots M2 water pump 3, observes required flow, the pressure surge situation of user.So iterative cycles, constantly adjusts interval time, until the fluctuation of flow, pressure can meet the normal requirement of producing of user, can guarantee again to leave certain surplus capacity for stand by pump drops into.The low limit value of pressure low limit, flow that final definite stand by pump is dropped into is in control program, and this device just can automatically drop into use.
