Abstract
The invention relates to an all-automatic system for controlling above-liquid type pump installed in a pump room. Specifically, the system fills and retains water in suction pipe of the pump so as to ensure the pump start or stop at any moment. The system mainly includes vacuum tank, vacuum pump, and control console suitable for above-liquid type pump with intermittent working condition. The invented system conoperate in conjunction with other system for controlling pump and pool to realize unmanned duty in pump room and remote monitoring. The system provides features of working stability and easy installation, debugging and maintenance.
Description
The present invention proposes a kind of full-automatic vacuum control system for pumphouse above liquid level, specifically is used for the suction hose vacuum dehydration of liquid following formula water pump, and the system of maintenance makes water pump start and stop at any time.
At present, the water filling of suction hose has dual mode before the liquid following formula pump startup, mainly uses manually-operated, promptly adds heavily to the difficulty of the work, and makes the work inconvenience again.
Purpose of the present invention proposes a kind of full-automatic vacuum control system for pumphouse above liquid level at the deficiency that prior art exists.
The object of the present invention is achieved like this, and the present invention mainly is made up of vacuum tank, vacuum pump, control box.Level switch is housed in the vacuum tank, and it has two contacts, is used for liquid level in the controlling tank, and control element is housed in the control box, is used for controlling vacuum system, water pump operation, pond liquid level and transmit pump house ruuning situation to Surveillance center.Control box can be away from the siphon tank body, and control box can be controlled vacuum system separately, also can control vacuum system and pond, water pump, and water pump is moved automatically.The present invention is 1 unit with each pumping plant, has the function to transmitting data in addition, needs as the user, can constitute wired/wireless dispatching net, and the various information transmission of pumping plant to the control room or central control room (CCR), are realized the function of distant place remote measurement.Principle of work of the present invention is: before water pump is devoted oneself to work, start vacuum system earlier, air in the vacuum pump aspiration vacuum jar of vacuum system, pressure tank is reduced, water in the pond will upwards flow along connecting pipe and water pump suction pipe, be full of suction hose gradually, water pump, when water level arrival vacuum tank hangs down liquid level, just can start water pump, when water level rises to the high liquid level of vacuum tank, stop vacuum pump, damage vacuum pump to prevent the vacuum pump water inlet, the small leak of upstream line and vacuum system enters the peak-vacuum tank of vacuum system, a jar interior liquid level is reduced, with the height in the vacuum tank, low level switch, the start-stop of control vacuum pump remains between the two position liquid level, at any time be full of water like this in the suction piping, also start and stop water pump at any time just, vacuum tank and pond connecting pipe are at starting mode of pump or when stopping, the balance pipe of the pressure in the balance vacuum tank.Vacuum pump M of the present invention
1Join by connecting pipe and vacuum tank 1, vacuum tank 1 joins by connecting pipe and pond, and vacuum tank 1 links to each other with maintenance valve C, maintenance valve C pass through connecting pipe again respectively with water pump M
2And pond 2 is continuous, and the pond liquid level switch S is housed in pond 2
2With fluid level transmitter L
T, dress vacuum tank level switch S in the vacuum tank 1
1, at maintenance valve C and water pump M
2On the connecting pipe that links to each other vacuum meter D is housed.Automatic control process of the present invention is divided into full-automatic and manual mode: manually generally be used for debugging, after the bringing normally into operation, be in full-automatic mode.During automated manner, after system powers on, start vacuum system, the water pump suction pipe liquid level rises gradually, make water pump suction pipe be full of water, the start and stop of vacuum pump are for keeping in the suction hose at any time (no matter be starting mode of pump or stop) all being full of water, and this just keeps water pump start and stop at any time.The water pump operation system is the start and stop with many water pumps of water collecting basin liquid level control, considers that pond liquid is fullyed recover from an illness, the start and stop interval time of flow of inlet water (level change speed) and each pump.The automatic control process is to make water pump operation system and vacuum system, pond liquid level chain by Programmable Logic Controller (PLC), to guarantee the fully automatic operation of system.Adopt the control principle of manual intelligent, import the control corresponding rule, determine the platform number of starting mode of pump time and operation.Pumping plant is realized unmanned fully.Adopt PLC each pumping plant to be controlled automatically stable and reliable operation.It can also select local operation or control automatically by selector switch.When choosing automatic control, every operation is realized by automatic operation.The then manually start and stop of control pump when choosing local operation.Pumping plant provides interface for the SCADA of Long-distance Control.
The present invention is applicable to intermittently used liquid charging pump, makes water pump start and stop at any time, cooperates the control system linkage work in water pump, pond, realizes the unmanned of pump house, remote monitor.The present invention adopts wireless SCADA system and senior configuration software can increase and decrease control station more neatly owing to central control system, thereby can be easy to satisfy the needs that real system is transformed, and therefore, system configuration is convenient.Working stability of the present invention is easy to Installation and Debugging, and is easy to maintenance.
Fig. 1 is a process principle figure of the present invention.
Embodiment:
The present invention can work under the 86-106Kpa condition at 0-95%, atmospheric pressure at environment temperature 0-50 ℃, ambient humidity, and serviceable life is more than 20 years.
