Product Description

                                                                     Product introduction
LGThe automatic high-rise heating vector pressure regulating water supply equipment has the function of variable flow, first, dissipate the external network traffic, pressure changes, the unit automatically adjusts to ensure high area system water flow. The same pressure.
Second, when the demand for system traffic in the high zone changes due to user sub-metering and other reasons, the unit automatically adjusts the heating flow while the backwater is consistent with the external network. In this way, no matter how the traffic is changed, it can be fully ensured that the backwater in the high zone has no impact on the low zone, ensuring normal and safe operation in the low zone, more energy-efficient and low-carbon, and lower running costs.
Low investment cost
Unattended
run smoothly
easy installation
Small footprint, high degree of automation
Heating the high-rise buildings in the basement complex
For the terrain elevation is too large mountain temple building height heating
Thermal power plant coal warehouse heating




                                                                          Features
High efficiency and energy saving, constant pressure of water supply, complete functions, programming control, reliable operation, simple operation, perfect protection function, long service life and strong anti-interference ability.
                                         Applications
Urban and rural water pumping stations, gas stations, residential areas, hotels, restaurants and other large public buildings living water and fire water. Various types of industrial and mining production and domestic water. Heating, air conditioning hot and cold water circulation system. Agricultural irrigation and drainage, sprinkler irrigation and musical fountains.

(If the user requires negative pressure water absorption, then according to user requirements separate design diversion device)
                                                  principle
The pressure sensor or flowmeter will be converted into electrical signals into the automatic control box, the signal through the automatic control box after the operation feedback to the inverter, the inverter by changing the frequency to change the motor speed, so as to change the pump at any time, will be the operation of Constant water pressure at a certain point to be determined, and the flow rate according to the size of the water changes, not only to achieve energy saving, but also safe and reliable.
The device is the parallel connection of multiple pumps, when the water consumption is less than or equal to a single pump working flow, the variable frequency pump starts to work, the water consumption gradually increases beyond the single pump working flow, the power frequency pumps have been put into operation, while the variable frequency pump Play a trace role in regulation. When the amount of water is gradually reduced, one by one to stop working frequency pumps, until the variable frequency pump.
The unit is also equipped with a pressure pump or pressure tank, when the amount of water is very small, the pressurized water stored in the pressure tank or pressure pump to provide pressure water to maintain the system, variable frequency pump to stop working, its energy saving effect is better.
The unit is composed of one to four main pump, a constant pressure pump (or pressure tank), water mains, valves, automation instruments, automatic frequency conversion control box and so on, so it is easy to install and compact. Ex-factory rigorous testing, stable performance.
