The叠压供水系统 consists of municipal water supply networks, anti-backflow devices, vacuum inhibitors, and flow regulators (flow compensators), pump units, automatic control cabinets, high-level tanks, and user water supply networks. The flow compensator is connected between the pump intake and the municipal water supply network, serving as a sealed container with vacuum suppression. It automatically completes vacuum detection, processing, control, execution, and digital feedback functions through a signal detection system, a microcomputer processing system, and a digital display system, effectively suppressing negative pressure at the inlet of the flow regulator tank to eliminate the negative pressure generated by the pump and achieve flow regulation and stabilization. The vacuum inhibitor is installed at the top of the flow regulator tank. The user water supply network is directly connected to the pump unit's outlet pipe, while the high-level tank is connected at the end of the user water supply pipe, with a liquid level sensor positioned within it.
Advantages of the Multi-stage Pump Products:
Compared to the same period last year, energy saving for traditional variable frequency pumps exceeds 70%.
2. Ultra-quiet technology reduces noise by over 100 decibels, addressing the issue of machinery disturbance affecting people during the traditional water supply process with pumps.
3. Saves space; no need for a pump room; can be placed freely indoors and outdoors; covers less than 10% of the original equipment.
4. The pollution-free, pressure-free, and water hammer-resistant filtration components are made from food-grade materials such as stainless steel, forming a sealed system to prevent secondary water contamination and meet international water hygiene standards.
The equipment allows for automatic control, pricing of pump installation and maintenance, and features manual/automatic switching, pressure regulation, constant pressure, high/low voltage protection, phase loss protection, overload protection, water shortage and voltage drop protection, non-water shutdown protection, and instantaneous tripping protection. It can also be equipped with timed rotation of primary and secondary pumps, visible remote control adjustment, detection, and maintenance as per user requirements.
6. In the event of a power outage, the water pressure can be automatically adjusted by switching to municipal tap water, ensuring a constant water supply pressure within the pipeline at all times. To avoid fluctuations caused by pressure variations in the municipal water network, the top floor is not equipped with a submersible pump brand, enhancing customer satisfaction.
7. In the event of any pump unit failure in the water supply equipment, it is easy to install and repair. Disassembly and assembly can only be done after the valves at both ends of the pump unit are closed, without affecting the normal operation of other pump units. The equipment design is more automated and rational, which is equivalent to the need for manual protection and maintenance.
Energy-Saving Principles:
By ensuring no negative pressure in the municipal pipeline system, we maximize the existing water pressure from the tap.
Secondly, we select appropriate, efficient, and high-quality submersible pumps and motors.
In maintaining the original water supply quality, the company has effectively integrated multiple sets of equipment from various regions of the original medium-to-high areas into a single set, thereby reducing the basic energy consumption points of multiple sets of equipment.
Based on consistent pressure and flow rates, the computer controller can precisely control the pump's power, start and stop, and achieve optimal operating conditions.
Considering the above circumstances and daily experience in Nanjing pump maintenance, the use of pressure boosting pumps is more advantageous in high-rise residential complexes.
