Integrated peak shaving water supply booster pump stationOverview
HuazhenIntegrated peak shaving water supply booster pump stationA new type of frequency conversion equipment. Divided into box type non negative pressure variable frequency equipment and tank type variable frequency non negative pressure equipment. The system is connected in series to the municipal water supply network where the pressure is insufficient. By detecting the outlet pressure through sensors and comparing it with the set value, the required increase in pressure value is calculated to determine the number of water pumps to be put into operation and the motor speed. This device maximizes the utilization of the original pressure of the municipal tap water pipeline network, without generating negative pressure on the municipal pipeline network. It replaces old-fashioned water tanks with stainless steel water tanks or non water tanks, reducing secondary pollution of water use. It is a new generation of energy-saving products in the field of water supply.

Integrated peak shaving water supply booster pump stationsurvey:
The integrated pumping station for domestic tank pumps in Huazhen Water Supply Production mainly consists of a sealed structure water tank, boosting equipment, variable frequency control cabinet, stabilizer, and pump group. The system is divided into two inlet channels, one into the water tank and the other into the stabilizer. When the water consumption is low and the tap water service pressure is high, the integrated pump station of the living tank directly draws water from the tap water pipe network and supplies water by stacking. When the tap water service pressure is low, the boosting device starts to work, pressurizing the water in the water tank to the set service pressure and compensating for the difference, thereby achieving the goal of energy saving, no secondary pollution, and constant pressure water supply. It has no impact on the municipal water supply network and is an energy-saving product in the water supply field.

three.Functional characteristics of integrated pump station for living tank pump
1Maintain constant pressure
The integrated pump station of the living box detects the outlet pressure in real time through a pressure sensor, compares the detected value with the set value, and determines the number of motors and pumps to be put into operation and the output frequency of the frequency converter (reflected as the motor and pump speed), in order to achieve the goal of constant pressure water supply. When the pressure fluctuation of the tap water network causes the pressure value to be lower than the normal pressure value, and the inflow is temporarily lower than the outflow, the system automatically closes the stabilizing device to a suitable position and starts the boosting device to pressurize through multi-point water intake. It knows that the inlet pressure has reached the normal pressure value of the municipal tap water network, ensuring that the equipment has sufficient water intake to meet the user's water demand.
2Highly automated
The system can achieve fully automatic control and has manual capabilities/Automatic switching, timed rotation of main and auxiliary pumps, pressure adjustment, constant voltage, high and low voltage protection, under phase protection, leakage protection, overload protection, overheating protection, water shortage protection, no water stop, instant trip protection and other functions. Alternatively, the human-machine interface can be configured according to user needs, allowing for visual remote adjustment, monitoring, and maintenance.
3Hygiene
The overcurrent components are made of food grade materials such as stainless steel, which comply with water related hygiene regulations.
4Stacked operation, saving costs
The system ensures constant pressure in the pipeline by adjusting the number of units and operating speed according to changes in water consumption. When the water consumption is high, the input power is high, and when the water consumption is low, the input power is low. When the water consumption is low (such as at night), the system is supplied with a low-power pump with variable frequency speed regulation and constant pressure water supply. The system has been running efficiently. Therefore, it greatly reduces operating costs. Can save energy60%The above.
If there is a certain pressure in the municipal pipeline network, the operation only needs to supplement the pressure on the basis of the municipal pressure. Compared to traditional water supply equipment with reservoirs, it achieves the same function while drawing less power from the power grid.
The system operates fully automatically without the need for dedicated personnel to be on duty: and due to the lack of civil water storage facilities such as reservoirs, as well as water quality treatment instruments, regular cleaning, disinfection, and other work are eliminated. Therefore, it further reduces operating costs.

Working principle of integrated peak shaving water supply booster pump station
The integrated peak shaving water supply booster pump station adopts pneumatic water supply. Using sealed tanks to increase local pressure for water supply purposes. The specific working sequence is to use a water pump to press water into the tank through a check valve, compressing the gas inside the tank and gradually increasing the pressure. When the pressure reaches the upper electrical contact pressure gauge, the pump will automatically stop through the control cabinet. The water pressure in the equipment is higher than the external pressure, and it is automatically sent to the water supply network. When the water level inside the tank drops and the air pressure decreases to the lower limit position, the electric contact pressure gauge restarts the water pump through the control cabinet. Repeat this process repeatedly, causing the equipment to continuously supply water. When the gas in the tank is insufficient, the gas replenishment valve can automatically replenish the gas.

4. Multi stage pressure water supply mode HLXB (A) intelligentPressure pump for domestic water supply tankMultiple water supply methods can be set according to the characteristics of users' water use. Generally, different pressure water supply can be provided for six periods a day to meet the needs of users. The time setting can be operated and modified on the human-machine interface, which is simple and convenient to operate.

Integrated peak shaving water supply booster pump stationWorking Principle:
Integrated peak shaving water supply booster pump stationPut into use, the water from the tap water network enters the water supply tank, and the air inside the tank is discharged from the vacuum eliminator. After the water is filled, the vacuum eliminator automatically shuts off. When the pressure of the tap water network can meet the water requirements, the system supplies water directly to the water network through a bypass check valve; When the pressure of the tap water network cannot meet the water demand, the system pressure signal is fed back to the variable frequency controller through a remote pressure gauge. The water pump runs and automatically adjusts the speed and constant pressure water supply according to the amount of water used. If the running water pump reaches the power frequency speed, another water pump will start variable frequency operation. When the water pump is supplying water, if the water volume in the tap water network is greater than the flow rate of the water pump, the system will maintain normal water supply; During peak water usage, if the water volume in the tap water network is less than the flow rate of the water pump, the water in the supply tank can still be supplied normally as a supplementary water source. At this time, air enters the supply tank through a vacuum eliminator, and the vacuum inside the tank is destroyed, ensuring that the tap water network does not generate negative pressure. After the peak water usage, the system returns to normal water supply. When the water supply network is shut down, causing the liquid level in the water supply tank to continuously decrease, the liquid level detector will feedback the signal to the variable frequency controller, and the water pump will automatically stop to protect the water pump unit. The water supply tank can store and release energy, avoiding frequent starting of the water pump.
