Stainless steel fountain pump motor control and protection of common lines are as follows.
(1) stainless steel fountain pump star delta control starter protection circuit
Start, close the power switch, turn on the power, lights HLG. Press the start button S. , The contactor KM energizes and makes the contactor K2 and the time relay K3 energize, the main contact of the contactor K2 connects the stainless steel fountain pump motor stator winding to the star, the electric motor starts the step-down start, the starting signal lamp HLY is bright at the same time; When the time relay extends , The contactor K2 is disconnected and the contactor K1 is energized. At this time, the main contact of the contactor K2 is opened first, and then the main contact of the contactor K1 is closed to transfer the stator windings of the submersible motor into triangles Normal operation under the connection, lights HLY, HLG off, running lights HLR light.
Stainless steel fountain pump motor overload and other failures in operation, the control switch FR closed through the middle of the relay K disconnect the control power to contactors KM and Ki power, disconnect the main power supply, the motor stops running, while running signal HLR off, HA bells ring, lights HLY, HLG light.
Star-delta control of the start of a protective control device easy to control, low cost, for delta connection, power larger, with double cable leads to wells with submersible motors.
(2) stainless steel fountain pump Autotransformer step-down start control protection circuit
Start, close the power switch, turn on the power, press the start button, contactor 3KM power, and its contacts will be connected to the star-shaped autotransformer, and contactor 2KM and time relay K power, the motor starts buck start , Start signal lamp 2HL light; when the time relay delay is over, through the middle relay 2KB disconnect the contactor 3KM and 2KM, while the contactor 1KM power, the motor to the rated voltage normal operation, then start signal 2HL off, run Lights 1HL light.
On the stainless steel fountain pump motor, when the oil pressure inside the depletion of depletion of the device, the oil-poor protection of the signal contact action, issued a fuel-poor signal, through the intermediate relay 1KB disconnect the contactor, thus cutting off the power to oil-filled motor Stop working, this time, lights 3HL light.
The use of autotransformer step-down start control protection circuit for any connection of the stainless steel fountain pump motor, the use of a wide range.
(3) stainless steel fountain pump motor control and protection devices commonly used
Suitable for oil-filled wells with submersible motors, with a fuel-oil signal action circuit commonly used control and protection devices are GKD type and XKD type, XKQ type. Applicable to water-filled or dry stainless steel fountain pump motor, and has a water level control function of the common control and protection devices are JBXQ type.
