1. Product Introduction Series variable frequency speed regulation constant pressure (variable pressure) water supply equipment is a new type of water supply equipment with high efficiency and low consumption launched by our company using microcomputer numerical control technology.
This equipment adopts high-quality frequency converter, built-in and controller, which can automatically adjust the speed of the water pump and the start and stop of multiple water pumps according to the instantaneous pressure and flow changes in the pipe network. On the basis of meeting the user's flow demand, the water supply The pressure is always constant at the preset pressure value, and the pressure can also be adjusted according to changes in the required pressure.
The entire system has advanced technology, reasonable design, stable performance and reliable operation. It can replace the water tower, high-level water tank or pressure tank in the water supply system, which is efficient and energy-saving.
No negative pressure water supply equipment
2. Product performance
Using high-performance frequency converter, equipped with advanced digital microcomputer control technology, it has a high degree of automation and can realize constant pressure variables and multiple constant pressure variables. , multiple control methods for variable pressure variables, multiple start and stop modes, and pressure stability accuracy ±%.
Microcomputer controls multiple pumps (or submersible pumps) to achieve variable-frequency soft start, without inrush current, mechanical impact, and small wear. It can extend the service life of the equipment, improve the stability of the system, and reduce the impact on the power grid.
The microcomputer controller has powerful functions and flexible system design and configuration. It can design a water supply control system with up to one main pump and one auxiliary water pump according to needs.
Fully digital intelligent microcomputer control, operating parameters can be modified according to specific conditions, and more functions can be added according to user needs.
Set up multiple sets of water level signal interfaces, which can input several water level signals at the same time, and have water cutoff protection function.
Frequency conversion is non-negative
