Box type energy-saving water supply pump station

system composition

The intelligent box type energy-saving water supply system is an intelligent energy-saving booster water supply equipment that integrates food grade stainless steel water tanks, stainless steel pipelines, stainless steel valves, water pumps, energy-saving systems, intelligent variable frequency control cabinets, and complete sets of accessories. This series of equipment has perfect structure, advanced technology, reliable performance, stable operation, and simple operation. Users only need to connect one water inlet and one water outlet to complete intelligent automatic water supply.

(The complete set of accessories includes liquid level sensors, liquid level control float valves, pressure sensors, stabilizing tanks, shock absorbers, ladders, manholes, flanges, etc.)

Principle Description

Conventional building water supply system:Users first store water in the municipal pipeline network through a water tank, and then use a water pump to pressurize and output the water supply pipeline to complete the building's water supply. This water supply method not only wastes the original municipal pipeline network water, but also

The pressure (0.15-0.45MPa) causes great inconvenience to the cleaning, maintenance, and upkeep of the water tank (during the cleaning and maintenance process of the water tank, the water pump usually cannot complete the water supply, and the user must stop the water supply).

Green Tide brand intelligent box type energy-saving water supply system:It can ensure the full utilization of the water pressure of 0.15-0.45MPa in the municipal pipeline network without generating negative pressure, and can provide pressurized water supply by stacking and replenishing the water to save energy. It can also ensure that the normal water use of users is not affected during the cleaning and maintenance period of the water tank.

Before the operation of the intelligent box type energy-saving water supply system, the energy-saving system installed on the inlet pipeline first detects the municipal water supply pressure. When the municipal water supply pressure reaches the building's water supply requirements, the energy-saving system opens and directly provides the municipal pressure to the water supply pipeline to complete the building's water supply. The booster pump is in a dormant state; When the municipal water supply pressure is insufficient to meet the building's water supply requirements, the energy-saving system will transmit the undervoltage signal of the water supply pipeline into the frequency conversion cabinet, and the frequency conversion control system will control the pump group to perform pressure boosting operation, making up for the shortfall to complete the pressure boosting energy-saving water supply.

The operation mode of the intelligent box type energy-saving pump set is:Firstly, start one of the pumps to operate at an appropriate frequency and frequency according to the required water volume and insufficient pressure output by the system, and supply water through stacked pressure. If one pump reaches full speed but still does not meet the demand, start the second pump to make up for the difference, supply water through variable frequency constant pressure stacked pressure energy-saving, and increase the pumps in sequence. When the user's water consumption gradually decreases until it stops using water, the system gradually slows down the pump according to the feedback signal from the user's pipeline network until it enters a sleep state. The water pump stops running. When there is a pressure drop trend in the user's pipeline network due to the user's need to use water again, the system automatically wakes up the pump group and enters an automatic running state. Each pump automatically starts and runs in rotation according to the length of operation time, in order to maximize the service life of each pump.

characteristic

• energy conservation

When the municipal water supply pressure reaches the building's water supply requirements, the municipal water supply is directly completed, and the intelligent system puts the booster pump in a dormant state. When the pressure of the municipal pipeline network is insufficient to meet the water demand, the intelligent system increases the water pressure based on the pressure of the municipal pipeline network by adjusting the speed and number of variable frequency booster pumps, and compensates for the shortfall. Fully utilize the residual pressure of the pipeline network to achieve energy-saving effects.

• Power outage and continuous water supply

When the power supply line is cut off, the energy-saving system completes the municipal pressure water supply, thereby achieving uninterrupted water supply during power outages.

• Timed update function

The system is equipped with a timed shut-off of the water tank inlet, automatically completing the replacement of stored water, and maintaining the retention time of the water tank to ensure water quality, environmental protection, and hygiene.

• Highly automated safety

The system has fully automatic control performance, including manual/automatic switching, timed water storage updates, leakage protection, overheating protection, overload protection, water shortage protection, and other functions.

• Cycle start, mutual backup

In order to maximize the service life of each pump, the system is designed with each pump as a backup, starting and running in a cyclic manner according to the running time of each pump.

• Overpressure protection function

The mechanical ultra-high pressure protection function ensures that the system does not experience equipment damage due to ultra-high pressure water supply when the collected signal is disturbed by external factors.

• Municipal water pressure protection function

In order to ensure the designated direct supply pressure of the water plant, the system is equipped with a municipal pressure automatic protection function. That is, when the municipal pressure drops to the designated pressure of the water plant during peak water usage periods, the system automatically activates the pressure maintenance function. When the pressure returns to above the designated pressure, the buck tooth function is automatically released.

• Small flow, small pump, constant pressure

During the ultra-low peak period of water supply, the system automatically switches to the low flow auxiliary pump operation mode, reducing the number of main pump starts and operation time, achieving better energy saving and maximizing the system's service life.

• Save investment

The system integrates the pump unit and its energy-saving control part with the water tank, which can eliminate the need for a building pump room, save floor space, shorten the construction period, and achieve the effect of saving investment and optimizing the combination.

• Low noise

The water pump and its energy-saving control system are hidden in the water tank, completely isolating noise from the outside world and meeting the standards of a quiet environment.

• Storage and self-sufficiency function

When the municipal water supply is insufficient or there is a short-term water outage, the system automatically replenishes the stored water in the water tank to the user's pipeline network to meet their water needs, thereby ensuring that users are not affected by pressure fluctuations in the pipeline network or short-term municipal water outages, and achieving a certain degree of storage self-sufficiency.
