System can realize running 12 groups of plans at most.The time that the plan that wherein can set in the works starts and lasting time, the measuring pump numbering that the nutrient solution needs that can select needs to add control and the magnetic valve numbering that needs are opened.And can arrange separately each magnetic valve and measuring pump.
The Main Function of mixing pump part stirs rich water mixed liquor, makes it more even.Therefore need according to actual conditions, carry out manually opened.When needs stir, manually opened, mixing pump will stop after 1 hour automatically in operation, if run duration has special circumstances or has satisfied the demand, and can hand brake at any time.Timing controlled: mixing pump automatically stops after startup brings into operation 1 hour, this part needs the timer used in system to realize.Non-follow control: if midway needs to stop, then have corresponding switch to disconnect, mixing pump is stopped.As shown in Figure 4.
Phase sequence is reported to the police: phase sequence alarm portion adopts phase sequence relay, and under normal circumstances, protector connects normally closed electric shock, be in conducting state, after phase sequence is made mistakes, phase sequence relay is automatically received and is often opened electric shock, be in off-state, at this moment PLC just can detect that this changes, thus produces phase sequence warning;
Raw water pump overcurrent warning: raw water pump overcurrent is reported to the police and mainly relied on electrothermal relay to realize, and when current is excessive, will produce larger heat, and when heat acquires a certain degree, relay disconnects, thus creates overcurrent warning, also protects raw water pump.
Frequency converter overcurrent is reported to the police: when the electric current flowing through frequency converter exceedes rated current 10%, be considered as overcurrent, then often can be held by normally closed becoming by the switch in the middle of frequency converter and PLC, thus create overcurrent alarm signal.
Raw water pump water flow switch report to the police: in internal system, a preliminary surveying can be carried out to the instantaneous delivery of raw water pump, if the umber of pulse of instantaneous delivery in 3-5s lower than certain value, then think that raw water pump does not have current, will water flow alarm be produced.
