Description
Technical field
The utility model belongs to a kind of clean water supply field, particularly relates to a kind of high-pressure cleaning device control system.
Background technology
Existing technology supplies water to high-pressure cleaning device by arranging two pump housings with frequency converter, the first pump housing work is first made when needs raise hydraulic pressure, second pump housing is restarted when first pump housing arrives power frequency state, when hydraulic pressure is higher need step-down time, then need the control decline low-power first making second pump housing at frequency converter; When the power as still needed step-down then then to reduce by first pump housing under power frequency state after second pump housing stops completely; Because frequency converter makes power rise to the frequency conversion state of required adjustment again as needed reduction power needs first to be reduced to by its power after zero under power frequency state, variation in water pressure is comparatively large in the process, easily causes damage to the pump housing and pipeline.
Utility model content
In order to solve foregoing, the present invention devises a kind of high-pressure cleaning device control system.
Technology contents of the present invention is: a kind of high-pressure cleaning device control system, comprise casing, the pump housing, frequency converter, controller, pressure inductor, water filter one end is connected to water source place by feed pipe, and the other end is connected to water tank and the pump housing in turn by feed pipe; Pump housing outlet pipe end is provided with high-pressure cleaning device; The described pump housing, controller, water filter, water tank are integrated to be arranged in same casing;
The pump housing is divided into pump housing first and pump housing second, and pump housing first and pump housing second are connected respectively frequency converter first and frequency converter second; Frequency converter first is connected on the controller with frequency converter second by electric wire;
Pump housing outlet pipe part is provided with hydraulic inductor, and hydraulic inductor is connected on the controller by electric wire.
Controller is provided with touch-screen.
Beneficial effect
Controller independently changes the power of two frequency converters according to the change of outlet pipe pressure when frequency converter does not reach full range state, in the process of step-down, avoid because frequency converter is converted into by power frequency the larger pressure oscillation that conversion process medium frequency bust produces for zero pair of equipment, proterctive equipment does not suffer damage, and increases the service life; Water filter removing silt is set, reduces silt to the erosion of equipment.

Detailed description of the invention
See Fig. 1-5: a kind of high-pressure cleaning device control system, comprises casing, the pump housing, frequency converter, controller, pressure inductor, and water filter one end is connected to water source place by feed pipe, and the other end is connected to water tank and the pump housing in turn by feed pipe; Pump housing outlet pipe end is provided with high-pressure cleaning device; The described pump housing, controller, water filter, water tank are integrated to be arranged in same casing;
The pump housing is divided into pump housing first and pump housing second, and pump housing first and pump housing second are connected respectively frequency converter first and frequency converter second; Frequency converter first is connected on the controller with frequency converter second by electric wire;
Pump housing outlet pipe part is provided with hydraulic inductor, and hydraulic inductor is connected on the controller by electric wire.
Controller is provided with touch-screen.
Specific embodiment:
Controller independently changes the power of two frequency converters according to the change of outlet pipe pressure when two motors all do not reach power frequency state; When starting working to when in device, hydraulic pressure raises, the power that controller first makes frequency converter first control pump housing first increases, when frequency converter first increases frequently (not reaching 50 hertz) pump housing first close to stopping it during power frequency state, and the power starting to start frequency converter second control pump housing second increases;
When hydraulic pressure is too high need to carry out step-down time; the power that controller first makes frequency converter second control pump housing second starts to reduce; start to carry out frequency reducing to frequency converter first until frequency converter second quits work; all the time power frequency state is not reached because controller controls frequency converter first, second; the frequency discontinuity that frequency converter avoids from power frequency state transfer when being frequency conversion state; thus making hydraulic pressure in device keep one state comparatively stably, the protection pump housing does not injure by water hammer.
Pump housing first and pump housing second major loop are connected respectively frequency converter first and frequency converter second, and two frequency converters are controlled by PLC; This device PLC is mainly interconnective and EM235 and EM232 composition;
Two frequency converters respectively correspondence are provided with contactor KM1, KM2; Relay K A1, KA2 is connected respectively between the FWD interface of frequency converter first and frequency converter second and com interface;
Frequency converter A-grade in the first class O1 interface is by being connected on RB, B+ two interfaces of EM235, and GND is connected on the B-port of EM235; AI2 port is connected on the MO interface of EM235, and GND is connected in the I/O interface of EM235;
Frequency converter second AO1 interface is by being connected on RC, C+ two interfaces of EM235, and GND is connected on the C-port of EM235; AI2 port is connected in the I/O interface of EM232, and GND is connected on the MO interface of EM232;
Touch control screen is connected on the relay of AC220V/DC24V specification; Pressure inductor connects relay by electric wire one end, and the other end is connected on the RA of EM235, A+ interface; L, N interface of relay is connected on M, L1 interface of CPU224.
