Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-4, in the utility model embodiment, a kind of water pump diversion effect on-Line Monitor Device, comprise diversion pipeline, inlet pipeline, rising pipe, centrifugal water discharge pump 401 and water pump diversion effect on-line monitoring device 405, described diversion pipeline comprises plunger type water flow switch 406, liquid jetting device 407, adjustment knob 101, output contact 102 and plunger switch 103, described diversion pipeline is provided with plunger type water flow switch 406, liquid jetting device 407; Adjustment knob 101 is equipped with at described plunger type water flow switch 406 top, and right side is provided with output contact 102, and plunger switch 103 is equipped with in inside; The characteristic that described plunger type water flow switch 406 has " water logical, flow of QI being obstructed ", namely, when there being gas by plunger type water flow switch 406, its output contact 102 can not action, when there being current by plunger type water flow switch 406, its output contact 102 closes, otherwise output contact 102 is opened.This function is that a plunger switch 103 with damping characteristic by being built in plunger type water flow switch 406 realizes, and water jet propulsion piston spring, to desired location, namely exports passive close switch amount signal by magnetic fields in dry reed-pipe.The damping characteristic (i.e. sensitivity) of this plunger switch 103 adjusts by adjustment knob 101.Described inlet pipeline comprises vacuum sensor 408, and described vacuum sensor 408 is arranged in inlet pipeline, described rising pipe comprises pressure transducer 402, electric gate valve 403 and safety check 404, described rising pipe is provided with pressure transducer 402, electric gate valve 403 and safety check 404, described diversion pipeline, inlet pipeline and rising pipe connect with centrifugal water discharge pump 401, output contact 102, pressure transducer 402 and vacuum sensor 408 are connected on water pump diversion effect on-line monitoring device 405, described water pump diversion effect on-line monitoring device 405 is core with CPU201, be configured with Analog input mModule 202, cut-in pressure sensor signal 205, vacuum transducer signal 206, be configured with switching input module 203 simultaneously, the output contact signal 207 that monitoring plunger type water flow switch 406 exports, be configured with switching value output module 204, can send with the interlock signal 208 of miscellaneous equipment and drive audible-visual annunciator 209.
Before starting centrifugal water discharge pump 401, first start liquid jetting device 407, liquid jetting device 407 produces vacuum and the water in sump is sucked centrifugal water discharge pump 401, flows back to sump through plunger type water flow switch 406.At this moment water pump diversion effect on-line monitoring device 405 will read output contact 102 signal of plunger type water flow switch 406.According to the signal pulse width of output contact 102, the signal simultaneously gathering pressure transducer 402 and vacuum sensor 408 carries out comprehensive descision to diversion effect, water pump diversion effect on-line monitoring device 405 starts timing when monitoring the rising edge 302 of water switch closure signal pulse, and when monitoring pulse falling edge 304, timer resets.So just can the pulse width that plunger type water flow switch 406 sends be detected.Due at the diversion initial stage, gas, water admixture in diversion pipeline, so water switch output contact signal is rambling pulse signal 301, only have after reaching normal diversion effect (namely diversion pipeline is full of water all the time) that a continuous print closure signal 303 can be exported.Water pump diversion effect on-line monitoring device 405 can pass through detecting switch output contact signal pulse width, and the auxiliary degree of vacuum to centrifugal water discharge pump 401 water sucking mouth and these two parameters of water outlet pressure are comprehensively come accurately to judge diversion effect simultaneously.If reach normal diversion effect, this device can send the interlock signal 208 with miscellaneous equipment.If due to reasons such as centrifugal water discharge pump 401 gas leakage, desirable diversion effect cannot be reached, then water pump diversion effect on-line monitoring device 405 cannot detect a sufficiently long pulse signal of pulsewidth within the time of setting, and audible-visual annunciator 209 will send acoustooptic alarm signal.
The utility model is except the said equipment, and remaining part is prior art, is not described in detail at this.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
