Description of drawings.
Fig. 1 is microcomputer controlled variable-frequency speed-regulating supply equipment figure
The specific embodiment
Water system has reservoir 12, and reservoir connects a plurality of water pump 11 pump groups, and a plurality of water pumps connect is responsible for net 8.Reservoir is by tap water 13 feedwater.
Be responsible on the net 8 in the water outlet of water supply network, water pump 11 pump groups exit 9 in parallel reverse terminal 10 is provided with shunt conduit 1, and pipe end and resource of water supply link, and on the shunt conduit 1 electrically operated valve are set.According to the pressure requirement of water outlet person in charge net water outlet port, shunting discharge is carried out auto-control.Be responsible for online in water outlet, the water outlet port position, order is arranged in parallel two pressure sensors 3,4, wherein, pressure sensor 3 is connected with standby work system 6 in the Control System of Microcomputer equipment, pressure sensor 4 is connected with main work system 5 in the equipment, and the two is used for providing person in charge's net pressure data to control appliance.
In the Control System of Microcomputer equipment, main work system 5 is set, this system is by microcomputer and programming, data to pressure sensor 4 are gathered, and water pump is opened, stops control and by frequency converter pump rotary speed is regulated and control according to water supply requirement, be responsible for the constant of net water side mouth pressure thereby reach water outlet; Be provided with standby work system 6 in the control appliance simultaneously, this system is connected with electrically operated valve 2, pressure sensor 3, under the situation that receives main work system fault-signal, back-up system can be devoted oneself to work automatically, data to pressure sensor 3 are gathered, and according to the requirement of pressure of supply water, to water pump open, stop and electrically operated valve 2 is regulated and control, thereby realize water outlet is responsible for the regulation and control of the branch streamflow of online shunt conduit 1, realize that the safe free of discontinuities constant and that supply water of water outlet person in charge net water side mouth pressure is carried out.
Be provided with manual duty selecting arrangement in the control appliance, as selected manually to open the pump work state, the pressure that then can use " manual pressure setting device 7 " that the net port is responsible in water outlet is set, this device is that system relies on equipment sparing work system 6, be connected with pressure sensor 3, electrically operated valve 2, confirm by 6 pairs of manual setting values of standby work system, and according to this numerical value requirement, water pump is opened, stops and electrically operated valve 2 is regulated and control, thereby realize that water outlet is responsible for net water side mouth pressure and is constant at manual setting value.
By microcomputer control, opening automatically under the pump work state, can be according to the difference of water supply discharge, the different pump housings that automatically switch are realized energy conservation object; Utilize microcomputer that the shutdown of water pump is switched simultaneously and carry out sequencing control, eliminate the generation of water hammer.
Enforcement by the aforementioned techniques scheme, realized manually, freely the selecting of automatic mode, freely the setting of ductwork pressure, and under the control appliance master work system failure condition, standby work system is devoted oneself to work automatically, and reaches and the identical technique effect of use frequency converter.
