Abstract
The utility model relates to a water supply-automatic control box, which solves the problems that an existing self-priming pump does not have the protection of overcurrent, short circuit and earth leakage; the existing self-priming pump are incapable of long distance control and display. The utility model has the technical scheme that an air circuit breaker QS, main contacts of contactors KM1, KM2 and a break contact YK of a line pressure controller are orderly connected between a power supply and a motor; one end of an intermediate relay KA is connected with a fire wire between the break contact YK of the line pressure controller and the motor and the other end is connected with a zero wire of the power supply; the contactor KM1 is connected with a manual button in series; the contactor KM2 is connected with a make contact FP of a liquid level controller in series; each contactor of the intermediate relay and the contactor KM2 is respectively connected with an anhydrous indication light UD, a water pump run indication light LD and a water pump stop indication light 2HD in series. The utility model can provide the protection of overcurrent, overload, short circuit and earth leakage for motors of water pumps and can realize remote control for the water pumps.
Description
Technical field
The utility model belongs to water controller.
Background technology
The system controlled by computer waterworks are adopted in urban water supply at present more, but its cost height, because self-priming pump is easy to use, thus often adopt self-priming pump to supply water in some occasion, but there is following point in it,
1, no overcurrent, overload, short circuit, earth leakage protective device;
2, no tangible duty indication;
3, the water source is anhydrous, can't auto stop, and this will burn motor.
Content of the present utility model
The purpose of this utility model is the deficiency that solves prior art, develops a kind of automatic control box for the self-priming pump motor, and its technical scheme is as follows.
A kind of feedwater automatic control box is characterized in that connecting the main contact of automatic air circuit breaker QS, contactor KM1, the main contact of contactor KM2 and the break contact YK of line pressure controller successively between the input end of power supply and motor; One of auxiliary reclay KA terminates on the break contact YK and the live wire between the motor of line pressure controller, and the other end is received on the zero line between contactor KM1 main contact and the automatic air circuit breaker QS; Contactor KM1 connects with moving disconnected button SB2, contactor KM2 connects with the moving together contact FP of fluid level controller, the break contact of contactor KM2 is connected with the anhydrous pilot lamp UD in water source, the moving together contact of auxiliary reclay KA is connected with water pump operation pilot lamp LD, the break contact of auxiliary reclay KA stops pilot lamp 2HD with water pump and connects, above-mentioned five series circuits are in parallel with power light HD, connect making button SB1 and main the order on the power lead of receiving behind the button LA between contactor KM1 main contact and the automatic air circuit breaker QS again.
The utility model is work like this, when starting water pump, and the automatic air circuit breaker QS that at first closes, the master that closes then makes button LA, send to control circuit.Press start button SB1, A.C. contactor KM1 gets electric, its main contact closure, and power light HD is bright.If this moment, there was water at the water source, the moving together contact FP closure of fluid level controller, contactor KM2 coil gets, its main contact closure, when hydraulic pressure did not reach setting value in the supply channel, the break contact YK of line pressure controller was in closure state, electric motor starting, auxiliary reclay coil KA gets, water pump operation, pilot lamp LD is bright, if the pipe network internal pressure has reached setting value, the break contact YK of line pressure controller is in off-state, water pump stops automatically, auxiliary reclay KA dead electricity, and it is bright that water pump stops pilot lamp 2HD lamp, water pump operation pilot lamp LD extinguishes simultaneously, shows that water pump shuts down.If the water source is anhydrous, then the moving together contact FP of fluid level controller disconnects, contactor KM2 coil losing electricity, and its main contact disconnects, and water pump shuts down, and anhydrous pilot lamp UD is bright.Artificially shut down in the water pump operation process, can press disconnected button SB2, make contactor KM1 dead electricity, so its main contact disconnects, motor is out of service.
Owing at the input side of power supply automatic air circuit breaker has been installed, for pump motor provides overcurrent, overload, short circuit and creepage protection function; Owing to contactor KM1 and KM2 and various pilot lamp are installed, have realized far distance controlled and indication to water pump operation; Owing to automatic level controller has been installed, thereby can have been realized anhydrous shutdown, avoided motor overheating to burn.
