Product Introduction

·Our company has independently developed another new type of water supply equipment product based on the non negative pressure variable frequency water supply equipment. It consists of five parts: water tank, pump group, steady flow tank, intelligent boosting and stabilizing device, and central control system. The equipment can utilize the pressure of the municipal pipeline network for non negative pressure variable frequency water supply, and can also draw water from the water tank for constant pressure variable frequency water supply equipment. It fully combines the advantages of constant pressure variable frequency water supply equipment and non negative pressure variable frequency water supply equipment. It uses air-cooled motors, air-cooled bearings, fully enclosed drip proof, with a noise level of less than 50 decibels to prevent small water tank space. It is a highly reliable non negative pressure variable frequency water supply equipment. The device also has a large remote (wireless) communication monitoring function and a user control room (optional); Humanized human-machine dialogue touch interface; Fully AI controlled and remote warranty pre service.

◆Product 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. ProtectionPressure: Regulating peak water usage, 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.

◆Scope of application

·1. Applicable geographical scope: Suitable for pressurized water supply in areas with sufficient pressure in urban pipeline networks;

·2. Applicable engineering types: production of industrial and mining enterprises, industrial water use, and large-scale intermediate booster pump stations for water supply in water plants;

·3. Applicable engineering location: secondary pressurization system for water supply;

·4. Other applicable scope: Domestic water for new construction, renovation, expansion of residential buildings, office buildings, hotels, restaurants and other public buildings.

Box type pump room with integrated box type frequency converterWater source issue:

Box type pump room with integrated box type frequency converterThe water source comes from the reservoir, so the pressure of the tap water is relieved, and the reservoir requires secondary disinfection equipment.Variable frequency booster pump for water tankIt is a stacked water supply method that directly utilizes the pressure of the tap water pipeline network, which is hygienic, energy-saving, and has low comprehensive investment. After installation and debugging, the water head of the tap water network enters the steady flow tank, and the air inside the tank is automatically eliminated through a vacuum eliminator.

Box type pump room with integrated box type frequency converter​Working Principle:
When the pressure of the public water supply network is ≤ 0.2Mpa (can be freely set to 0.2-0.4Mpa), the constant pressure device of the water supply equipment in the community will be turned off and the constant pressure inlet device will be turned on, and the water will be supplied by the water tank. Conversely, when the pressure of the public water supply network is ≥ 0.2Mpa, the constant pressure device will be turned on and the constant pressure inlet device will be turned off after a delay of 10 minutes (time adjustable), and the water will be supplied by the public water supply network. The water stored in the constant pressure water tank of the community's water supply equipment is intelligently controlled to circulate every 6 hours, ensuring fresh and pure water quality.
The variable frequency pump in the constant pressure water tank of the community's water supply equipment operates at a certain speed, utilizing the existing pressure of tap water to achieve superposition, ensuring that the pressure required by users is constant. The inlet of the variable frequency pump for the constant pressure water tank in the community water supply equipment is connected to the constant pressure device and the constant pressure inlet device. By opening and stopping the constant pressure device, negative pressure is not generated in the tap water network. At the same time as the constant pressure device starts and stops, the constant pressure inlet device will make the opposite action to the non negative device.
The constant pressure device for water supply in the tap water network will automatically shut down, and the constant pressure inlet device for the price water tank of the community's water supply equipment will automatically open and be supplied by the water tank. When the liquid level in the water tank drops to a certain level, the constant pressure inlet device will automatically shut down, the equipment will automatically stop, and it will automatically start running when power is restored.

Characteristics and analysis of integrated box type frequency converter in box type pump room:

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.

Box type pump room box type frequency converter integrated 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.

Box type pump room box type frequency conversion integrated technology innovation points:

1. Integrate the water tank and water pump used in the water supply system of the tap water pipeline, and place the water pump, control cabinet, non negative pressure device and other equipment in the water tank. Separate the equipment from the water in the water tank through the water tank partition. Due to the placement of the water pump inside the water tank (using a low-noise shielded pump), the noise of the equipment is greatly reduced.
2. The inlet of the variable frequency pump is connected to the non negative pressure device and the non negative pressure water device. When the pressure is sufficient, the non negative pressure device automatically opens, and the water is directly supplied by the municipal pipeline network, which is then pressurized by a booster pump to supply water to the user. When the non negative city device detects a decrease in pressure in the municipal pipeline network, the non negative pressure inlet device immediately starts and the non negative pressure device closes. At this time, the user pipeline is directly pressurized by pumping water from the water tank through the booster pump to ensure sufficient pressure in the user pipeline.
3. Intelligent solenoid valves are 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, intelligent control can be used. When the water level in the tank is below a certain level, the solenoid valve can be opened to release water from the pipeline, ensuring a certain pressure at the water intake. This measure can avoid peak water consumption and play a peak shaving role. It also avoids zero pressure discharge from ordinary water tanks, which is a good protection for pipeline pressure.
4. The water tank, water pump, pipelines, valves and other water related materials in this complete set of equipment are all made of food grade stainless steel materials, which will not cause secondary pollution to tap water. At the same time, the equipment is equipped with an intelligent circulation system, which automatically draws water from the water tank every 6 hours to ensure fresh water quality, hygiene and environmental protection.

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.
