Overview

Efficient no negative pressure constant pressure water supply equipment is my company's new development of a new generation of energy-saving water supply equipment. It is composed of no negative pressure water supply system and intelligent constant pressure control system. Non-negative pressure water supply system includes: no negative pressure tank, pressure tank parallel operation of 2-6 vertical stainless steel multi-stage centrifugal pump, control valves, piping, etc .; intelligent constant pressure control system includes: pressure sensors, level sensors, PID, frequency converter, touch screen, and control cabinet and so on.

Function features

No negative pressure, by pressure (or stack)
- due to the installation of no negative pressure tank, to avoid the phenomenon of negative pressure at the inlet, will not cause negative pressure on the municipal water pipe network.
- The equipment is pressurized by the water pipe network at the time of operation and pressurized on the basis of this, and the running time of the ordinary reservoir and the tank can reduce the number of pumps or reduce the speed to achieve energy saving.
Energy saving and environmental protection
- When the water consumption is large, the power is small and the water consumption is small. Small water consumption (such as night) system by the small power pump frequency control constant pressure water supply, the system has been operating at high efficiency; thus greatly reducing the operating costs; can save more than 60% of energy.
- Overflow parts are made of stainless steel food registration materials, in line with national wading health standards.
- box no negative pressure device to ensure that the water tank through the user water, daily automatic updates, real-time replacement, to ensure water sanitation.
Security and confidentiality
- If you need to change the settings, enter the password.
Highly automated, remote monitoring
- The system can realize automatic control, with manual, automatic switching, main and auxiliary pump timing rotation, phase, over voltage, under voltage, over current protection operation, high pressure, low pressure alarm, automatic inspection function to prevent pump idling, Running and other functions.
- Communication serial port can be linked with the computer to achieve direct control of computer networking, remote dial-up communication can be achieved through remote monitoring.
Book the run function
- Built-in alarm clock, the user can according to the actual size of water, set the operating pressure of different periods of time, to achieve the purpose of saving energy. Book run is divided into: run by the time, according to the week to run, run three ways.
Emergency measures, diagnostic sensor abnormalities
- When the inverter fails, the device automatically switches on the high manual control and automatically starts the emergency operation function at the same time.
- Low water level sensor, the pressure sensor failure, immediately stop the pump and alarm function.
