>>> Product Overview
KYG FREQUENCY CONVERSION CONSTANT PRESSURE WATER SUPPLY EQUIPMENT introduces the most advanced frequency conversion technology in the world, adopts imported famous brand frequency converter, and adjusts the speed and number of single or multiple pumps through the programmable controller to achieve closed regulation of constant pressure variable water supply, so that the water supply system can achieve the most reasonable and economical operation effect, and realize the automation of operation. The product has compact structure, complete functions and small footprint. It replaces the traditional water tower, high water tank and other water supply devices, saves project investment, shortens the project cycle, and avoids secondary pollution of water quality. The product conforms to the "JG/T3009-93 microcomputer Control frequency conversion speed regulation water supply equipment Standard" issued in January 1994.
>>>Product composition and structure
KYG FREQUENCY CONVERSION CONSTANT PRESSURE WATER SUPPLY EQUIPMENT is generally composed of three parts:
1. pump unit 2. air pressure tank 3. frequency conversion control cabinet.
1. Water pump unit
Water pump is the most basic product of water supply equipment, is the basic guarantee for water supply equipment to achieve its water supply capacity, KYG water supply equipment supporting pumps are the company's production of QDL, QDLF, KYL, GDL, LG and other series of pumps.
According to the different control program, you can choose the operation mode of fixed frequency conversion of the main pump and automatic alternate rotation of the rest of the standby pump, or you can choose the operation mode of alternate rotation of the main pump and the standby pump together, and the main and standby pumps are alternate to each other to prevent the standby pump from rust death for a long time.
2. Pressure storage device (pressure tank)
Energy storage is a complete set of water supply equipment in the components of its role is:
1) storage can stop to maintain pressure, to ensure that there is water at any time to open the tap.
2) cope with a small amount of water supply and normal pipe network leakage.
3) It has the effect of eliminating water hammer and pressure jitter.
>>> Feature
1. Efficient and energy saving
The system automatically adjusts the speed of the pump and the number of pumps according to the change of the user's water consumption, so that the equipment always runs under high efficiency conditions, and the energy saving effect is remarkable.
2. The water supply pressure is stable, and the working pressure can be determined according to demand
The system is closed regulation control, which automatically adjusts the difference between the actual pressure and the set pressure, so that the water supply pressure of the system is stable.
3. High degree of automation, easy operation, barrel
The system is controlled by programmable controller, which can realize unattended duty.
4. Perfect protection function
The system has a variety of protection such as short circuit, lack of phase, over current, over voltage, over heat and over load.
5. Extend the life of motor and pump
Multi-pump group cycle frequency conversion soft start, avoid the impact of current on the power grid when starting, eliminate the water hammer effect, according to the principle of first start, first stop, first start, regular pump change operation, so that each pump run balanced.
6. Reduce pollution and work
No need for high water tank and water tower device, avoid secondary pollution, but also avoid regular cleaning work due to high water tank.
7. Save investment and shorten the construction period
The equipment has compact structure, less land, less investment and short engineering period.
