Brake is the core missions of water quality monitoring system, and clear water is cleaned, sprayed, except algae, the miscellaneous function such as dry of drying all are to monitor
Function services.
As shown in figure 3, monitoring flow includes two links of water acquisition and water distribution：
(1) water acquisition link：Water sample is taken into water tank from water head site and is referred to as water acquisition.After flow startup is monitored first
Open draining valve, it is ensured that the water sample for not having last time measurement period to leave in water tank, be then turned off draining valve, while opening raw water
Valve.It must ensure that raw water valve could start water pump in open position and fetch water, the meeting of directly fetching water because raw water valve unlatching exception
Cause water pump to build the pressure and damage.When pump working rear water box starts constantly to inject water sample, when water level reaches liquid-level switch position
When, water level signal is simultaneously delivered to PLC by liquid-level switch action, and PLC is received to be stopped water pump and close raw water valve immediately after signal.So far
Water tank water intaking is completed.When the water source of monitoring is surface water, if not doing desilting processing and supplying water directly to instrument, it can cause to survey
Value is inaccurate or even instrument is damaged, thus needs that water sample is carried out to stand desilting processing；Multi-parameter probe is immersed in water tank water sample
In, after when the desilting of setting, time is up, PLC just can be to many ginseng sensor readings.
(2) water distribution link：Water sample in water tank is delivered into instrument and is then referred to as water distribution.The utility model is to be supplied water without pressure
Instrument is that Water Test Kits configures a sampling cup.Pressure charging valve and instrument water intaking valve are first turned on, it is necessary to confirm valve in unlatching
Booster pump could be opened behind position causes booster pump to damage to prevent from building the pressure.Water sample in water tank is simultaneously distributed to by supercharging pump work
In the sampling cup of instrument.Liquid-level switch is configured with sampling cup, is trigger position signal when water level to liquid-level switch position,
PLC, which receives signal, to be stopped supercharging pump work and closes instrument water intaking valve and pressure charging valve.So far instrument sampling cup water distribution is completed,
PLC trigger commands to Water Test Kits instrument starts measurement.After the completion of instrument monitoring, this monitoring flow is completed.Monitor above
The link failure of any one in cycle, requirements of process alarm is exited, and does reset processing to corresponding equipment.
Cleaning process mainly includes：Spray, clear water cleaning, hot water cleaning, blowing drying, particular flow sheet are as shown in Figure 4：
(1) spray：Raw water valve is closed, begin to rehearse water valve, instrument draining valve.Valve event in place after, open shower valve, clear water from
The mouth spray of water tank enters spray pipeline, and water aperture from tube wall sprays, the inwall of water tank is sprayed, to remove measurement week last time
The impurity on tank inner wall is retained in phase water sample, Fig. 2 is spray pipeline schematic diagram.
(2) clear water is cleaned：Shower valve, draining valve are closed, raw water valve, purge valve, booster pump, pressure charging valve, instrument is opened and enters
WaterValve(to confirm pressure charging valve, instrument water intaking valve in open position), now clear water since whole pipeline front end to pipeline carry out
Clear water is cleaned.Clear water cleaning process closes purge valve after terminating.
(3) hot water is cleaned：Purge valve is closed while the hot water opened in hot water valve, water heater is cleaned and removed to pipeline
Algae.Hot water is simple and effective except algae mode except algae, and algae can preferably be removed by heightening water temperature and extension time.Hot water removes algae
Flow closes hot water valve after terminating and empties the water in water tank and pipeline.
(4) blowing drying：The compressed air closed in the dry valve of hot water valve unlatching blowing simultaneously, gas tank dries dry to pipeline
It is dry, to remove residual water sample and the impurity on tube wall, the influence to next measurement period measured value is reduced as far as possible.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and deformation can also be made, these change
Enter and deform and also should be regarded as protection domain of the present utility model.
