Variable frequency water supply equipment is a complete set of water supply equipment which is directly connected with the municipal pipe network and will not affect the municipal pipe network.
On the basis of ZBH variable frequency constant pressure, the equipment overlays the pressure of municipal pipe network and lifting pump to make the domestic water supply more energy saving and environmental protection. It is an ideal replacement for traditional secondary water supply.
The equipment is composed of frequency conversion control cabinet, no negative pressure device, automatic control system and remote monitoring system, water pump unit, stable pressure compensator, negative pressure eliminator, pressure sensor, valve, instrument and pipeline system, etc.
Widely used in enterprises and institutions, residential areas and rural production, living, office water. The number of water supply households is 20-2000. The daily water supply is 20-50000m cubed, with a water supply height of 150 meters, that is, a 50 floors.
1. Remarkable economic benefits: by using this equipment, it’s unnecessary to build water tower or roof water tank , which not only reduces the construction period of the project, but also solves the disadvantages of high project cost, and also overcomes the disadvantages such as large fluctuation of air pressure and frequent start of pump.
2. Rigorous design: the equipment adopts variable frequency and constant pressure control of the pump. No matter how the water consumption of the system changes, the outlet pressure of the pipeline can be kept constant.
3. Reliable operation: the equipment adopts frequency conversion governor and high-quality water pump, which has perfect protection function and automatic and manual conversion function, making the operation very reliable, with good performance, flexible control mode and strong anti-interference ability;
4. High efficiency and energy saving: the equipment can adjust the speed of the water pump according to the change of user's water consumption, making the pump always work in the high efficiency zone, with obvious energy saving effect, which is 35% more energy saving than the constant speed pump;
5. Simple operation: the equipment adopts automatic control, PID adjustment and real color touch screen display.The operator only needs to change the switch of electric control cabinet to realize the operating condition required by the user and realize automatic unattended operation.
6. Complete protection functions: it has perfect automatic protection functions such as overload, short circuit, overvoltage, undervoltage, lack of phase, overcurrent, short circuit and water shortage. It can conduct signal alarm, self-check and fault judgment under abnormal circumstances;
7.Saving place and easy installation: the whole set of equipment has only water pump unit, control cabinet, diaphragm pressure tank and accessories, which is very simple and convenient to install.
8. Extended service life of pumps and motors: it can reliably realize soft start for multiple pump sets, make the power grid and pipe network free from impact, and operate in turn, greatly extending the service life of pumps and motors.
