The characteristic characters of the main and auxiliary pumps for cutting the yellow are not indicated as ordinary type, that is, the main and backup pumps are manually selected before starting the machine. When the main pump fails, the standby pump is automatically put into operation.
As: timing automatic switching / manual switching;
Ac: Alternate automatic switching/manual switching Multi-pump operation mode One-for-one preparation: control I, II two pumps, can work in "I main II prepare" or "II main I prepare" two ways.
Two with a prepared: control I, II, III three pumps, can work in the "I, II master III preparation" or "II, III master I prepared" or "I, III master II prepared" three ways.
Three-use and one preparation: control four pumps I, II, III, and IV, which can work in "main I, II, III preparation IV" or "II, III, IV master I preparation" or "I, III, IV master II "Preparation" or "I, II, IV Master III preparation" four ways.
Two uses: Can independently control I, II two pumps, can also be combined through the float ball to form "I with II prepared" or "II with I prepared." When the flow rate changes or the main pump fails, the liquid level reaches the standby pump start control point and the standby pump is automatically put into operation. This type is suitable for controlling the level of two water tanks, or for controlling variable flow water supply and drainage systems.
Three uses: can independently control I, II, III three pumps, but also through the combination of floating ball combination to form "I, II main III backup or II, III main I prepared or I, III main II prepared." When the flow rate changes or the main pump fails, the liquid level reaches the standby pump start control point and the standby pump is automatically put into operation. This type is suitable for controlling the level of three pools, or for controlling variable flow water supply and drainage systems.
Four-use: Independently control I, II, III, IV four pumps, and can also be combined through float assembly to form "I, II, III master IV preparation" or "II, III, IV master I preparation" or "I "Class III, IV, and Main II" or "I, II, IV Master III Preparation." When the flow rate changes or the main pump fails, the liquid level reaches the standby pump start control point and the standby pump is automatically put into operation. This type is suitable for controlling the position of four water tanks, or the terminology to control variable flow water supply and drainage systems.
Each of the above modes is equipped with a manual function. In the manual mode, each pump can be started and stopped manually.
Power inlet mode a, single power: all the way into the power line;
b, dual power supply: two-way power into the line, can be arbitrarily selected I with II prepared or II with I prepared, when the main power supply failure occurs when the power is automatically put into standby power.
Multi-pump control of the main and backup pump switching mode is not marked: ordinary type with a manual switch before the start of the main pump and standby pump selection. After the main pump fails, the standby pump is automatically put into operation. This method is generally used for the main and backup pumps.
As: Timed auto-switching/manual switching is applicable to occasions where the main and backup pumps need to be exchanged regularly, so that the long-term continuous working time is divided equally between the main and backup pumps. The regular switching time is 4/8 hours for selection. When there is no need for automatic switching at regular time, the main and backup pumps can be selected by switching to manual switching mode. This type has a standby pump self-shooting function.
Ac: Alternate automatic switching/manual switching is applicable to occasions in which the main and backup pumps need to alternately work alternately. Each time it starts, the main and standby pumps exchange once. When there is no need to alternate, the switch can also be used to switch manually to select the main, Prepare the pump. This type has a standby pump self-shooting function.
Control Type Description Unlabeled: Level Control. Using this type of high-performance Key Float switch, equipped with Italian technology, it can reliably realize the automatic control of changing the liquid level according to high and low levels, and the opening and shutting of the drainage pump. Other liquid level controllers such as OMRON can also be used according to user requirements.
P type: pressure control. With an external electrical contact pressure gauge or pressure controller, automatic pump opening and shutting off can be realized according to changes in pipe network pressure. This type is widely used in living water supply and fire booster systems. Because this box is also suitable for the control of the Key float switch water pump and the use of limit switches, button remote control and other ways to control, it is a "universal interface" motor control box, an extremely wide range of applications.
T-type: temperature control. External temperature controller, according to the set temperature range to open or close the pump, used in constant temperature, heat exchange systems.
S type: time control. The chassis panel of this type is equipped with a time setting button and a display, and the user can control the opening and closing of the water pump according to timing requirements, and is suitable for the control of various regular or regular intermittent operation modes.
K-type: air-conditioning pump control. This type is an accessory product designed for air-conditioning pumps. The pump is turned on by the manual or control center linkage operation. When the pump is running, it outputs a control contact condition for the start of the refrigeration unit. The control program of the air conditioning unit must be started after the pump is turned on to ensure safe operation.
X type: fire-fighting type. This type is designed according to the national fire code. Fire pump, spray pump start can be:
1, chassis panel manual;
2, each guy tying or pressure switch start;
3, the fire center DC24V start, and there are input to the fire center pump stop, pump open, pump failure signal contact point for instructions.
L type: Submersible sewage pump type. According to the characteristics of submersible pumps, this model not only has a short circuit in the main circuit, lack of phase, overload protection, but also has a pump body leakage protection and motor stator winding overheat protection and leakage protection.
Determination of the starting method Normally the pump with a motor power of 15 kW or less is suitable for direct starting.
Y: The starting current is small, the starting torque is small, and it can be started more frequently. The pump with the motor power of 15kW-45kW is suitable for the Y-Δ step-down starting, with the exception of the submersible pump.
Z: The starting current is small, the starting torque is large, and it cannot be started frequently. The pump with the motor power above 11 kW is suitable for the auto-coupling step-down starting when the starting is infrequent.
