Product Description
>>> Product Overview
Heating ventilation air conditioning is designed for pumps with central heating and central air-conditioning system. The start-stop of cold or hot water circulating pump is controlled by manual operation or center control center and linkage interface.
When pumps are running in the air-conditioning system, a control contact will be output for air conditioning unit's starting-up in order to realize the control sequence that pumps start before unit and air-conditioning unit stops before pumps and ensure the safe operation of air-conditioning system. The temperature signal of heat supply and cold or hot water circulating can be collected by temperature sensor. With temperature controller, the automatic start-stop of pumps can be controlled in accordance with the change of water temperature.
>>> FUNCTION DESCRIPTION
Water Pump Working Mode
1. One main and one standby:
When controlling 1 and 2 pumps, it can work in two states '1 main and 2 standby' or '2 main and 1 standby'. When the main pump breaks down, the standby pump will start to work automatically. Start manually by panel operation button. If the user requires to use both pumps, it is not necessarily to equip the standby pump.
2. Two mains and one standby:
When controlling 1, 2 and 3 pumps, it can work in three states '1, 2 main and 3 standby' or '2, 3 main and 1 standby' or '1, 3 main and 2 standby'. When the main pump breaks down, the standby pump will start to work automatically. Start manually by panel operation button. If the user requires to use all pumps, it is not necessarily to equip the standby pumps.
3. Three mains and one standby:
When controlling 1, 2, 3 and 4 pumps, it can work in four states '1, 2, 3 main and 4 standby' or '2, 3, 4 main and 1 standby' or '1, 3, 4 main and 2 standby' or '1, 2, 4 main and 3 standby'. When the main pump breaks down, the standby pump will start to work automatically. Start manually by panel operation button. If the user requires to use all pumps, it is not necessarily to equip the standby pumps.
Main Pump And Standby Pump Switch Mode
1. Manual switch:
Main pump and standby pump are switched manually. When the main pump has faults, the standby pump will start to work automatically.
2. Ac automatic alternative switch:
It is proper for the occasion where main pump and standby pump need to work alternatively. Once started, the main pump and standby pump will alternate one time. This type also has a function that the standby pump switches automatically if there is a fault.
3. As timing switch:
It is proper for the occasion where the pumps work frequently, which makes each pump's working time more average and prevents one pump's long time using and huge losses. It is switched at an interval time.
Start-up Mode
1. Direct start:
Full-voltage starting, full-voltage operation, large starting current.
2. Autotransformer start:
Voltage and current will be reduced by autotransformer when starting, and will be restored to rated voltage when operating.
3. Soft start:
Pumps are started by electric soft starter, there is no contact diverter during the start process, and voltage and current will rise smoothly, which will not make huge impact on power grid and pipe networks.
Additional Function
1. Timing start-stop:
Pumps can starts and stops at a predetermined time according to the time which is set by clock operated switches in the control panel.
2. Remote interface:
Electric control panel is equipped with remote monitoring terminals and can convey pumps' working condition to duty room in remote distance in order to be monitored.
3. BA interface:
Electric control panel is equipped with building automatic remote monitoring terminals, showing equipments' working condition and enabling start-stop controls.
4. Dual power:
Electric control panel is connected with dual power supply, which be switched automatically and manually.
WORKING ENVIRONMENT
1. mains voltage fluctuation:≤±10%;
2. surrounding environment temperature:-10-±40ºC(non-frozen);
3. air relative humidity:20%-60%(without condensation);
4. place without explosive danger;
5. place without conductive dust and gas which can corrode mental and destruct insulation;
6. vibration: <5.9m/s2( 0.6G), inclination:≤ 5°;
7. absolute altitude:≤1000m.
>>> PERFORMANCE CHARACTERISTICS
1. Simple circuit design and reasonable structure, which is convenient for faults analysis.
2. There are manual, automatic and remote control function, which can ensure the equipments' safe and continuous operation.
3. Excellent performance, flexible control methods, strong resistance to interference, steady and safe working condition.
4. Protection function: motor overload, short circuit, phase losses, pump casing leakage, motor stator overheat, safe usage, simple maintenance.
5. Programmed control, several control modes according to users' requirements such as several pumps' automatic alternative operation and timing start & stop.
6. High-power pumps can be started smoothly by frequency converter or smart soft starter.
>>> APPLICATION SPECIFICATION
As the control equipment of cold or hot water circulating pump (including heating and air-conditioning system), KYK-K control pump for circulating pump can meet all the technical requirements with protection function such as motor overload, phase loss and short circuit. Other start modes can also be chosen if necessary, such as star-delta start, auto-transformer start and soft start. Besides, the control loop of water pump can also be added in the circulating system
The control signal can also collect circulating water temperature signal and control the start-stop of circulating pump by temperature controller or interconnect with the linkage signal of air-conditioning main engine.

1. Heating System
2. Air Conditioning System
3. Frequency Conversion Energy-saving.
>>>HUMAN-COMPUTER INTERFACE
There are two kinds of configuration industrial human-computer interface.
1. Text display with simple function (Chinese interface) It can be set up some basic parameters and displays as picture and text forms.
2. Touching-type industrial figure display (touch screen)
There is a 32bit RISC CPU so that the operating speed is fast. Plenty of screenshots can be set up. The system state isdisplayed in the form of image and text combined. The interface communicates via touch screen, PLC (programmable logic controller) and frequency converter. Parameters such as working pressure and flow are set up via the touch screen. The touch screen also displays information on site such as each pump's working condition, real-time pressure, frequency and breakdown, etc. It's easy and simple to handle. The function of replacing control panel improves reliability of the system.
>>>NETWORK COMMUNICATION
Currently, many pumping stations, water plants and enterprises has formed an international popular industrial Ethernet standard based on TCP/IP, which is applied to remote monitoring operation condition of systems such as pump sets and electric. Field control system has programmable controllers and communication expandable modules and is connected to monitoring network via field bus. It has standard communication interface such as serial RS232/RS485, supports Ethernet and TCP/IP field bus base protocol and can remote control and monitor equipments.
