Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: 1, pressure control unit; 2, moisturizing control unit; 3, time control unit.
Embodiment
Embodiment
As shown in the figure, this device is primarily of compositions such as the pressure control unit 1 in dotted line frame, time control unit 3, moisturizing control units 2, and unit both can work alone, and realized corresponding function, also can collaborative work, realizes hybrid integrated and controls.When not needing to use this device, only needing to press X button and just can return to original state, not affecting the use of emulsion power pack.The main line of control loop is connected with main switching control QT1, for controlling unlatching and the disconnection of whole control loop.
The structure of unit and function thereof.
pressure control unit: the major function of this unit realizes the Pressure testing of emulsion power pack and the control of pressure.When emulsion power pack liquid supply pressure value is lower, lower than setting value, other relays can be passed the signal along to intelligently, and then realize unlatching and the disconnection of pumping plant.
Pressure control unit 1 is installed throw over switch QT2, a gear is connected with tutorial light R, and two gears are connected with tutorial light G and performance loop.Get to a gear, tutorial light R(red light) bright, represent that this unit does not work; Get to two gears, cut-in pressure control loop, tutorial light G(green light) bright, in representing that Pressure testing is carried out.Pressure switch KPR normally opened contact is connected with time relay KT, and on-delay normally opened contact KT connects with relay K A1.
Pressure switch KPR is DPST Series Intelligent pressure controller, has highi degree of accuracy, is arranged on the outer pipe of emulsion power pack.Time no one uses, emulsion power pack pressure lower than setting value, pressure switch KPR normally opened contact close, on time relay K T.Time relay KT time delay 10-15 minute (adjustable), on-delay normally opened contact KT closes, engage relay KA1.Off working state meeting engage relay KA1, relay K A1 is pressure control unit output relay.
2. moisturizing control unit: this unit can realize detection and the automatic water supplement of pump box water level, the function of lack of water pump trip.Moisturizing control unit is installed throw over switch QT2, a gear is connected with tutorial light R, and two gears are connected with tutorial light G and performance loop.This throw over switch QT2 is identical with the throw over switch function of a upper unit, is used to open or close moisturizing controlling functions.
Water level switch KD is arranged in emulsified liquid pump station water tank, and water level switch KD is connected with water tank liquid supply electromagnetic valve.Water level is lower than transition point, and water level switch KD closes, and connects solenoid valve, realizes automatic water-supply.Water level switch KD connects with relay K A2, and then controls emulsion pump.Work as water tank lacks water, relay K A2 is switched on.Relay K A2 is the output relay of this unit.
time control unit: this unit one is in whole day 24 hours, can set point punctual termination of pumping of any some time, in order to avoid personnel are not at the scene, pumping plant is no load running always; Two is coordinate pressure control unit to realize Pressure testing in a period of time and maintenance, if do not use pumping plant in a period of time, automatically controls termination of pumping, avoids waste.Time control unit is installed throw over switch QT3, a gear is connected with tutorial light R, and two gears are connected with tutorial light G and performance loop, and function is identical with a upper cell translation switch.Clock switch WD adopts micro computer clock switch, is set to the time of being on duty (such as early to 12 noon) at 8 and connects, all the other time separated.
After normally opened contact KA1, normally opened contact KA2, clock switch WD parallel connection, entirety is connected with relay K A3, and contactor KM connects with relay K A3 normally-closed contact.Normally opened contact KA1, normally opened contact KA2, clock switch WD three any one closed all represent abnormal state, relay K A3 all can be caused to electrically connect, and relay K A3 normally-closed contact disconnects, contactor KM dead electricity, and emulsion pump turns off.Recover normally, reclose switch QT1.
As shown in Figure 1, above-mentioned three unit, respectively with throw over switch QT2, QT2, QT3, are under any circumstance closed and open unit, not affecting original the functions of pumping stations completely.
First this innovation achievement has carried out testing in Heng Bang company of Zao Kuang group integrated plant and has used, in the middle of the emulsion power pack system this device being linked into this factory and control switch.
Such as: 1, Heng Bang company of Zao Kuang group integrated plant every morning 12 comes off duty, and come off duty thirty in the afternoon 5, pumping plant is set at the cut out of 11: 50 every morning, and closed in the afternoon 5: 20, occurs unmanned use never again and sky far turns phenomenon.
2, when pumping plant is jack pressure testing, sometimes only with tens minutes or half an hour, but user may not take into consideration to close pumping plant, and the adding of this system, DPST Series Intelligent pressure controller can be relied on to determine this situation intelligently, automatically control to close pumping plant, avoid waste.
If 3, the water of pump box " is drunk dry ", and pump no load running, easily damage pumping plant, after this system uses, can sensed water level automatically, water level is too low, will pump trip, and startup automatic water supplement function immediately, until the water of pump box is added to suitable standard.
In a word, coming into operation of this device solves the Automated condtrol problem of emulsion power pack breakthroughly, can greatly save human cost and power cost, and stopped the unmanned problem using no load running of pumping plant, intelligently detect the state of pumping plant and pump box, very clear, facilitate easy to operate, no matter economically or scientific and technological intelligent angle, all there is very large promotional value.
