Multi-pump mode of operation

One with a prepared: Control I and II of two pumps can work in two ways "I, II preparations," or II of the main equipment ".
With a prepared: control I, II, III three pumps can work in "I, II main III prepared" or II and III of the main equipment "or" I, III, II preparations, "in three ways.
With a prepared: control I, II, III, IV, four water pumps, working in the "I, II, III of the main IV preparations," or "II, III, IV, the main equipment" or "I, Parts III, IV of the Lord II prepared "or" I, II, IV of the main III prepared "in four ways.
Two things: You can independently control the I, II, two pumps can also be the float combinations connection, composed of the "I prepared with II II I prepared. When the flow changes or main pump failure, the level reaches the standby pump start control point of automatic standby pump. This type of control two pool level, or used to control the variable flow to the drainage system.
Three: independent control of the I, II, III, three pumps, also available through the float combinations connection, composed of I, II, III prepared of II, III of the main equipment or the I, III, Master II ". When the flow changes or main pump failure, the level reaches the standby pump start control point of automatic standby pump. This type of control of three pool level, or used to control the variable flow to the drainage system.
Four: You can independently control the I, II, III, IV, four water pumps, also available through the float combinations connection, composed of I, II, III of the main IV preparations, "or" II, III, IV, the main equipment "or" I , III, and IV of the Lord II prepared "or" I, II, IV, the main III prepared ". When the flow changes or main pump failure, the level reaches the standby pump start control point of automatic standby pump. This type of tuck bits in the control of four pools, or language to control the variable flow to the drainage system.
The above model, with manual features, the pump in manual mode you can manually start and stop.

Power line way

a single power supply: the way power line;
b, dual power: Road power line, can choose I prepare II or II I prepared when the main power failure, power failure, the BZT.

Multi-pump control of the main and backup pump switching mode

Unlabeled: ordinary type
Before starting the manual switch to select the main pump and standby pump. Primary pump failure, the standby pump automatically put into the general main and backup pump control in this manner.
As: timing switch automatically / manually switch
Lord, and prepare pump the need for regular exchange of occasions, to make long-term continuous time-sharing in the standby pump. Conventional switching time 4/8 hours to select type. No timer automatically switches the available switches to manual switch to select the main and backup pump. This type has a spare pump to self-cast feature.
Ac: alternating switch automatically / manually switch
For the main and backup pump alternating occasions, start time, Lord, prepare pump exchange, do not need the turn, also be used to switch to manual switch to select the main and backup pump. This type has a spare pump to self-cast feature.

Control Type Description

Unlabeled: level control. The use of this type with Italian technology to produce high-performance Key float switch can reliably achieve a high level, low transformation automatically control to the drain pump open downtime. Equipped with OMRON and other liquid level controller according to user requirements.
P-type: pressure control. External electric contact pressure gauge or pressure controller can be realized automatically by changes in the pipe network pressure pump, and off the pump. The type used in a large number of domestic water supply and fire pressurization system. As the box is also applicable to Key float switch control pumps and limit switches, buttons, remote control and other control, it is a "universal interface" motor control box, a very wide range of applications.
Type T: temperature control. External temperature controller, according to the set temperature range of open-pump or off pump, used in the constant temperature, heat exchange system.
Type S: time control. In this type chassis panel with time setting buttons and display, the user can control the timing need to control the pumps on and off, for a variety of regular or regular intermittent.
K type: air-conditioning pump control. This type is designed for the air conditioning pump accessory products. Pumps open to the linkage by the manual or the control center operations, pump run-time output to a control contact conditions for the boot of the refrigeration unit must first open the pump and air conditioning unit control procedures to ensure safe operation.
X-type: Fire-type. This type of design specifications by the National Fire The fire pump, sprinkler pump start by:
A chassis panel manually;
2 small bolt or pressure switch to start;
Fire Center DC24V start, and lost to the fire center, pump stop, pump on, the signal contacts of pump failures do instructions to use.
L-shaped: the submersible sewage pump type. According to the characteristics of the submersible pump of this type in addition to the main circuit short-circuit, phase loss, overload, overheat protection and leakage protection of pump leakage protection and stator windings.

Starting method to determine

General motor power below 15kW pump suitable for direct starting.
Y: small starting current, starting torque is small, more frequent start-up, the motor power of 15kW-45kW pump suitable for the Y-△ voltage starting, the exception to the submersible pump.
Z: starting current, starting torque large, frequent start, water pump, starter motor power 11kW more than the infrequent occasions are suitable for auto-voltage starting.
