Main and standby pump switching mode characteristics: not marked as common type, that is, the main and standby pumps are manually selected before starting the machine. When the main pump fails and shuts down, the standby pump is automatically put into operation;

As: timing automatic switch/manual switch;

Ac: Alternate automatic switching/manual switching

Multi-pump working mode

One for use and one for backup: control two pumps of I and II, and can work in two modes of "I main and II standby" or "II main and I standby".

Two-use and one-standby: control three pumps I, II and III, and can work in three modes of "I, II main and III standby" or "II, III main and I standby" or "I, III main and II standby".

Three uses and one backup: control four pumps I, II, III, IV, and can work in "I, II, III main IV standby" or "II, III, IV main I standby" or "I, III, IV main II" There are four ways of "backup" or "I, II, IV main and III backup".

Dual use: It can independently control two pumps of I and II, and can also be connected by floating ball combination to form "I use II backup" or "II use I backup". When the flow changes or the main pump fails, the liquid level reaches the starting control point of the standby pump, and the standby pump is automatically put into operation. This type is suitable for controlling the liquid level of two pools, or for controlling the water supply and drainage system with variable flow.

Three-purpose: It can independently control three pumps I, II, and III, and can also be connected by floating ball combination to form "I, II main and III backup or II, III main and I backup or I, III main and II backup". When the flow changes or the main pump fails, the liquid level reaches the starting control point of the standby pump, and the standby pump is automatically put into operation. This type is suitable for controlling the liquid level of three pools, or for controlling the water supply and drainage system with variable flow.

Four-purpose: It can independently control four pumps I, II, III and IV, or can be connected by floating ball combination to form "I, II, III main and IV backup" or "II, III, IV main and I backup" or "I , III, IV main II backup" or "I, II, IV main III backup". When the flow changes or the main pump fails, the liquid level reaches the starting control point of the standby pump, and the standby pump is automatically put into operation. This type is suitable for controlling the tuck position of four pools, or the water supply and drainage system with variable flow.

The above modes are all equipped with manual function. In the manual state, each pump can be started and stopped manually.

Power entry method

a. Single power supply: one power supply line;

b . Dual power supply: Two-way power supply input line, you can choose I for II standby or II for I standby, when the main power supply fails and power outages, the standby power supply is automatically turned on.

Main and standby water pump switching mode of multi-pump control

Not marked: ordinary

Use the manual switch to select the main pump and the backup pump before starting the machine. When the main pump fails, the standby pump is automatically put into operation. Generally, this method is adopted for the control of the main and standby pumps.

A s: timed automatic switching/manual switching

　It is suitable for occasions where the main and standby pumps need to be exchanged regularly, so that the long-term continuous working time is equally divided between the main and standby pumps. The normal switching time is 4/8 hour selection type. When it is not necessary to switch automatically at regular intervals, the switch can be switched to manual switching mode to select the main and standby pumps. This type has the function of automatic switching of the standby pump.

Ac: Alternate automatic switching/manual switching

　　It is suitable for the occasions where the main and standby pumps need to work alternately. Each time the pump is started, the main and standby pumps are exchanged once. This type has the function of automatic switching of the standby pump.

Control Type Description

Not marked: Level control. Using this type of high-performance Key float switch produced by Italian technology, it can reliably realize the automatic control of the start and stop of the water supply and drainage pumps according to the change of liquid level high and low. Other liquid level controllers such as OMRON can also be used according to user requirements.

Type P: pressure control. With an external electric contact pressure gauge or pressure controller, the pump can be automatically turned on and off according to the change of the pipe network pressure. This type is widely used in domestic water supply and fire pressurization system. Since this box is also suitable for controlling the water pump with the key float switch and controlling the water pump with limit switch, button remote control, etc., it is a motor control box with a "universal interface" and has a wide range of applications.

Type T: temperature control. An external temperature controller is used to turn on or off the pump according to the set temperature range, which is used in constant temperature and heat exchange systems.

Type S: time control. The panel of this type of chassis is equipped with time setting buttons and a display, the user can control the opening and closing of the water pump according to the timing needs, and is suitable for the control of various timing or regular intermittent working modes.

Type K: Air conditioning water pump control. This type is a matching product designed for air-conditioning water pump. The pump is turned on manually or by the linkage operation of the control center. When the pump is running, it outputs a control contact condition for starting the refrigeration unit, realizing the control program that the pump must be turned on first and then the air-conditioning unit to ensure safe operation.

Type X: special type for fire fighting. This type is designed according to the national fire code. The fire pump and sprinkler pump can be started by:

1. The chassis panel is manual;

2. Each guy bolt or pressure switch starts;

3. The DC24V of the fire center is started, and there are signal contacts for pump stop, pump on and pump failure input to the fire center for indication.

L type: special type for submersible sewage pump. According to the characteristics of the submersible pump, this type not only has the main circuit short circuit, phase loss, overload protection, but also has the pump body leakage protection and the motor stator winding overheat protection and leakage protection.

Determination of starting method

Generally, pumps with motor power below 15kW are suitable for direct start.

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 Y-△ step-down starting, except for the submersible pump.

Z: The starting current is small, the starting torque is large, and frequent starting cannot be performed. The water pump with a motor power of more than 11kW is suitable for the use of auto-coupling step-down starting when the starting is infrequent.
