Variable frequency constant pressure water supply equipment

Variable frequency constant pressure water supply equipment

feature

High Efficiency and Energy Saving

It can automatically detect and adjust the speed (power consumption) of the electric motor based on the actual water consumption and pressure of the user, so that the equipment is always in a high-efficiency working state.

Stable pressure in the water supply network

The automatic closed-loop control is composed of a microcomputer, which can restore the changing pressure to normal within 0.5 seconds, and the pressure adjustment accuracy is ± 5% of the set value.

Small footprint, low investment, and short installation period

Compared with other old-fashioned water supply equipment, it saves 3-16 times the land occupation and 15% -60% of investment compared to building water towers. The equipment has a small volume, easy assembly, installation and debugging, and a short transportation and installation period.

Full protection function, safe and reliable operation, easy operation

The host adopts an imported frequency converter, which has protection functions such as undervoltage, overvoltage, overcurrent, overload, short circuit, overheating, stall prevention, etc. It has been used for more than 100000 hours. The power distribution control part of the equipment adopts intelligent control principles, which are easy to operate and practical. The working status of the equipment is clear at a glance, making it easy for non professionals to quickly master.

Full water supply function, high insurance factor

When a local malfunction occurs, the emergency function can be activated to continue supplying water. Liangbang equipment can automatically connect to the municipal water supply network and has dual constant pressure function, which can meet the normal pressure and flow of domestic and production water. It can automatically switch to high-pressure and high flow water supply in case of fire, and can be used for multiple purposes.

Variable frequency constant pressure water supply equipment

Scope of application:

The water supply pressure is 0.15~2.0MP, the water supply height is 10-200 meters, and the hourly water supply of a single set of equipment is 10~50000m3/h. It can be used for the matching transformation of large, medium and small tap water; Can be used for production, living, and office water in enterprises, residential areas, and rural areas.

Principle of Variable Frequency Control for Constant Pressure Water Supply Equipment

Using variable frequency speed regulation to achieve constant pressure water supply has a significant energy-saving effect compared to using regulating valves to achieve constant pressure water supply (which can be calculated according to specific situations). Its advantages are:

a、 Starting balance, the starting current can be limited within the rated current, thus avoiding the impact on the power grid during starting;

b、 Due to the decrease in the average speed of the pump, the service life of the pump and valves can be extended;

c、 It can eliminate the water hammer effect during start-up and shutdown.
