It does not generate negative pressure when pumping, and the indoor box type integrated pump station has certain regulation and storage capacity, and can continuously stop water supply during peak periods.

◆Stainless steel intelligent pump room integrated boxProduct advantages

·1. Adequate water supply: The box type non negative pressure water supply equipment can be connected in series with the municipal pipeline network to ensure that no negative pressure is generated in the municipal pipeline network. During peak water usage periods, the water in the closed water tank can be pressurized by computer-controlled variable frequency adjustment of the water pump, avoiding the flow of water required by users due to insufficient supply from the municipal pipeline network.

·2. Intelligent water supply: When the public water supply network is ≤ 0.2Mpa (can be freely set to 0.2-0.4Mpa), the non negative pressure device is turned off, the non negative pressure inlet device is turned on, and the water is supplied by the water tank; On the contrary, when the pressure of the public water supply network is ≥ 0.2Mpa, the delay time is 10 minutes (time adjustable). The non negative pressure device is turned on and the non negative pressure inlet device is turned off, and the water is supplied by the public water supply network.

·3. Clean water source and constant pressure: The water stored in the non negative pressure water tank is intelligently controlled to circulate every 6 hours to ensure fresh and clean water quality. The variable frequency pump of the box type non negative pressure water supply equipment operates at a constant speed, utilizing the existing pressure of tap water to achieve superposition and ensure the pressure required by the user is constant.

·4. Protection pressure: peak water usage is regulated, and an intelligent solenoid valve is used at the inlet of the water tank to control the inlet pressure and water level. When the pressure in the pipeline decreases and the booster pump draws water from the water tank, it can be intelligently controlled. When the water level in the tank is lower than the liquid level, the solenoid valve is opened to release water from the pipeline, ensuring the pressure at the water intake. This measure can avoid peak water usage and play a role in peak regulation. Secondly, it avoids zero pressure discharge from ordinary water tanks and provides good protection for pipeline pressure.

·5. Intelligent booster pump: When the tap water pressure can meet the user's water requirements, the booster pump is controlled to be in a sleep state through frequency conversion. When water is not used during peak hours and the tap water pressure cannot reach the user's water pressure, the water pump can add pressure to the tap water pressure (0.2-0.5MPa) to make up for the difference and fully utilize the remaining pressure to save electricity and energy.

·6. Environmentally friendly and pollution-free: All water passing materials of the product are made of 304 food grade stainless steel, and the matching pressure tank and water sealing material meet hygiene standards, which can avoid various water source pollution problems in traditional water tanks.

·7. Intelligent frequency conversion: During the stacked water supply period, the device can fully utilize the pressure potential energy of the municipal water source itself, compensate for the difference, and maximize the energy-saving effect of frequency conversion speed regulation.

·8. High efficiency and energy saving: In order to further reduce energy consumption and avoid excessive work, the product adopts automatic variable voltage control technology. This technology also effectively solves the problem of critical flow oscillation that is prone to occur during the transition process of adding and subtracting pumps, and improves the comfort of water supply.

·9. The designed frequency conversion control cabinet has high intelligence: it realizes the detection, alarm, and automatic switching of two water sources; Unified scheduling and reasonable management of water tank replenishment, storage, water source switching, and pressurization operation have been achieved.

Characteristics and Analysis of Stainless Steel Intelligent Pump Room Integrated Box:

The water consumption of users is generally dynamic, so situations of insufficient or excessive water supply may occur from time to time. The imbalance between water use and supply is mainly reflected in the pressure of water supply, where more water is used and less water is supplied, resulting in lower pressure; If there is less water and more water, the pressure is greater. Maintaining a constant water supply pressure can balance the supply and use of water, with more water supplied when using more and less water supplied when using less, thereby improving the quality of water supply.
The water pipeline pressurization equipment is very important for users. In the production and daily water supply, if the tap water supply is insufficient or temporarily cut off due to reasons, it may affect the quality of life, and in severe cases, it may affect survival safety. In the event of a fire, if the water supply pressure is insufficient or there is no water supply, it cannot be quickly extinguished, which may cause significant economic losses and casualties. Therefore, adopting a constant pressure water supply system in the water use area can generate significant economic and social benefits.
With the development of power technology and the continuous improvement of fully automatic tower free water supply technology, the intelligent water supply control system with no negative pressure variable frequency water supply equipment as the core has replaced the previous high-level water tank and pressure tank water supply equipment. The starting is smooth and the starting current can be limited to the rated current, thus avoiding the impact on the power grid during starting; Due to the decrease in the average speed of the pump, the service life of the pump and valves can be extended; It can eliminate the water hammer effect during start-up and shutdown. Its stable and safe operating performance, simple and convenient operation mode, and comprehensive and thoughtful functions will enable water supply to achieve water-saving, energy-saving, and labor-saving, ultimately achieving the goal of efficient operation.

Stainless steel intelligent pump room integrated box description:

1. Basic Description of Box Pump Station Control Technology:
The box pump station system is set with a constant pressure value. If the pipeline pressure is higher than the set pressure value, the pressure transmitter will feedback the pipeline pressure to the variable frequency control cabinet. The tap water can be directly supplied to the user's pipeline network through the direct supply pipeline. When the pressure of the municipal pipeline network changes or the water consumption of the user pipeline network changes, causing the pipeline pressure to be lower than the set pressure, the pressure transmitter feeds back the pipeline pressure to the PlD controller in the frequency conversion control cabinet. The PlD controller adjusts the output frequency of the frequency converter, starts the water pump unit, and adjusts the pump speed to maintain constant pressure water supply; If the water supply requirements cannot be met, the control cabinet will control the start and stop of multiple power frequency pumps and the speed of variable frequency pumps to achieve the requirement of constant pressure variable water supply.
2. Basic Description of Negative Pressure Elimination Technology for Box Pump Station
The box pump station adopts microcomputer frequency conversion technology and effective negative pressure treatment technology to achieve stacked water supply Specifically, as follows:
The non negative pressure variable frequency water supply equipment achieves direct serial connection with the tap water pipeline network through a vacuum compensation system and a fully enclosed structure, and overcomes the adverse effects on the pipeline network. The non negative pressure variable frequency water supply equipment collects the vacuum degree and water level signals inside the steady flow compensator through the pipeline pressure gauge, vacuum suppressor, and detection device in the steady flow compensator, and provides real-time feedback. The special devices in the vacuum suppressor and steady flow compensator are controlled by a microcomputer to suppress the generation of negative pressure and ensure that the equipment does not affect the urban pipeline network.
When the municipal pipeline network is shut down, the water pump unit can still work until the pressure in the steady flow compensator drops to the lower limit pressure set by the electrical contact, and then automatically stops. It will start automatically when water comes in. When there is a power outage, the water pump unit stops working, and tap water can enter the user's pipeline network through a direct pipeline. When a call is received, the unit automatically starts up and resumes normal water supply.
