Abstract
The utility model relates to a self-locking circuit used for a water pump of a diatomite filter. The self-locking circuit helps to solve problems of the prior art that once a conventional water pump of a diatomite filter is out of power, diatomite adhered on a filter screen falls due to loss of voltage and then production stops. A main circuit of the self-locking circuit is a soft start circuit, a control circuit is control to work both locally and remotely in a self-locking manner, and a power failure alarming device is also added. The self-locking circuit enables probabilities of power failure to be substantially minimized and plays a key role in improving stability of copper foil production.
Description
Technical field
The utility model relates to the control circuit technical field, especially relates to a kind of latching circuit that is used for the diatomaceous earth filter water pump.
Background technology
The electronics Copper Foil is the important materials during copper-clad plate (CCL) and printed circuit board (pcb) are made, and diatomaceous earth filter is one of visual plant during Copper Foil is produced.The diatomaceous earth filter water pump is got to clean liquid bath with tail washings groove solution by diatomaceous earth filter, finishes filtration.In this process,, then can cause production to stop because decompression comes off attached to the diatomite on the screen pack if the diatomaceous earth filter water pump is jumped electricity.The process that is coated in screen pack owing to diatomite is very complicated, can't resume production in the back short time that comes off, and can cause very big loss.Produce for Copper Foil, guarantee that it is vital that the diatomaceous earth filter water pump normally moves to greatest extent.
The utility model content
Jump the deficiency of electricity in order to overcome existing diatomaceous earth filter water pump, the utility model provides a kind of latching circuit that is used for the diatomaceous earth filter water pump, and it can reduce the probability that the diatomaceous earth filter water pump is jumped electricity, improves the stability of system.
The technical scheme that its technical problem that solves the utility model adopts is: be used for the latching circuit of diatomaceous earth filter water pump, be made up of main circuit and control circuit, control circuit can be realized long-range and local operation, and long-range and local control forms latching circuit.
Described main circuit is by three phase mains L1, L2, L3, and knife switch QS, thermal relay KH, soft initiator link to each other successively, and bypass relay K M is in parallel with soft initiator, the serial connection motor M, and the electric motor starting mode is a soft start.
Described Long-distance Control is PLC output relay normally opened contact K control, and this locality is controlled to be auxiliary relay normally opened contact KA1 control.
Described Long-distance Control K and local control KA1 are in parallel and all be in closure state, form latching circuit, bypass relay coil KM always electric, water pump normally moves.
Described control loop has increased the jumping electric alarm device by soft initiator fault output relay normally opened contact KA2 control.
The utility model beneficial effect is: the mode that adopts long-range and local control to work simultaneously, the advantage that has kept two kinds of control modes, the water pump of having avoided causing because of factors such as interference, power network fluctuation or faults is jumped, and can avoid because misoperation causes water pump to quit work, improve the stability and the efficient of producing greatly.
Description of drawings
The utility model is described in more detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model electric control theory figure.
Embodiment
Fig. 1 is the utility model electric control theory figure.Main circuit is by three phase mains L1, L2, L3, and knife switch QS, thermal relay KH, soft initiator (ACS3-55) link to each other successively, and bypass relay K M is in parallel with soft initiator, the serial connection motor M, and the electric motor starting mode is a soft start.Soft initiator (ACS3-55) x1 end is ac terminal, wherein 2 connects the alternating current 220V power supply, and 3 ground connection connect the timing closing normally opened contact of time-delay relay KT between 9 and 10, and 5 and 6 connect the output of power transfer relay, closure during fault, and 6 meet power transfer relay coil KA2; The x2 end is dc terminal, and wherein 1 is the startup of soft initiator, connects+the 24V DC power supply, and 1 has met remote control switch K and local K switch A1 among the figure, and long-range and local switch can be controlled the startup of soft initiator respectively, and 3 is the fault end, and 7 is common port.
The startup of motor can be adopted local and remote control, should first closed knife switch QS before the electric motor starting.During local control, press start button SB2, the coil of auxiliary relay KA1 gets electric, its normally opened contact KA1 closure, and the soft initiator start end gets electric, and soft initiator starts.During Long-distance Control, only need PLC control output relay K coil electricity, the normally opened contact K closure that links to each other with 1 end of soft initiator x2, soft initiator starts.After soft initiator starts, the main circuit energising, motor begins to start.The coil electricity of time-delay relay KT, behind the main circuit energising 10s, the timing closing normally opened contact closure of time-delay relay KT, bypass relay K M coil gets, the normally opened contact KM closure of the bypass relay in parallel with soft initiator, electric motor starting finishes, and soft initiator switches to the bypass relay, and motor normally moves.
When motor wants out of service, only need make the coil blackout of bypass relay K M, its normally opened contact KM recovers off-state, can realize the stall of motor.By pressing local stop button SB1, the KA1 normally opened contact is disconnected; Remote PLC control makes normally opened contact K recover normally open simultaneously.
In practical operation, local control separately can't be read and be reported to the police and trip signal, and long-range independent control can be disturbed the influence with the signal broken string, if a long-range and local end misoperation can make pump directly jump.Now make local K switch A1 and remote control switch K closed simultaneously, local and remote control constitutes latching circuit.Adopt thisly from lock control, when an end misoperation appearred in the scene, Local or Remote control had a switch to work, the coil of bypass relay K M be in always electricity condition, water pump is in running order always.Stop button under long-range and local control respectively only, water pump can stop.
The latching circuit main circuit of diatomaceous earth filter water pump uses the defencive function of thermal relay and soft initiator self to provide protection as motor.Control loop increases jumps the electric alarm device.When breaking down in the main circuit, the coil of the fault output relay KA2 of soft initiator gets electric, utilizes the normally opened contact control warning device of KA2 to realize jumping electric alarm in control circuit.
