Product Introduction

Our company develops and producesIntegrated smart water supply equipmentIt is a type of secondary pressurization that can be connected in series to the urban government management network for usersNon negative pressure variable frequency booster pumpThe factory does not need to build reservoirs or high-level water tanks, and is directly connected in series to the municipal pipeline network. When the equipment operates normally, it will not create negative pressure (suction) on the municipal pipeline network, which meets the requirements of China's "Urban Water Supply Regulations" and can fully utilize the existing pressure of the municipal pipeline network. The energy-saving effect of using variable frequency speed regulation water supply method is extremely significant. After being introduced to the market, it has been highly favored by Fangda users.

Water is the source of human life, and human survival cannot be without water for a day.
With the continuous improvement of urbanization level in our country, the urban population has increased sharply, and the continuous expansion and renovation of urban residential buildings have led to the continuous increase of residential floors and the expansion of urban areas. The pressure on the original municipal pipeline network is becoming increasingly insufficient, and in most areas, there is a widespread problem of low water supply pressure during peak periods, making it difficult for high-rise users to use water.
So most buildings add secondary pressurization equipment, build reservoirs and high-level water tanks, which can pass through water pumpsNon negative pressure variable frequency booster pumpfactory However, this traditional secondary pressurization equipment has many disadvantages such as high investment and easy secondary pollution of water sources.

The building water supply boosting system adopted in China has roughly gone through four stages:
The stage is to adopt“Water storage tank+water pump+high-level water tank”The method involves municipal water entering a storage tank, which is then pressurized by a water pump and sent to a high-level water tank. The high-level water tank supplies water to users, and the reservoir serves as a regulating device during peak water usage;
The second stage is to adopt“Water storage tank+water pump+pressure tank”The method involves municipal water entering a storage tank, which is then pressurized by a water pump and sent to a pressure tank. The pressure tank supplies water to users, and the storage tank serves as a regulator during peak water usage;
The third stage adopts“Water storage tank+constant pressure variable frequency water supply system”After setting the water supply pressure of the system, the speed of the water pump and the number of water pumps put into operation change with the change of water supply under the control, and the output pressure remains constant, which to some extent saves electricity consumption.
In the fourth stage of pipeline network pressure (no negative pressure) water supply era, equipment is directly connected to the municipal water supply network without the need to repair water storage tanks, fully utilizing the pressure of the municipal water supply network. The equipment has the characteristics of high efficiency, energy saving, environmental protection, no secondary pollution, high degree of automation, and easy maintenance, gradually becoming a rational water supply method for modern buildings.

Integrated smart water supply equipmentworking principle

This device adopts microcomputer frequency conversion technology and negative pressure processing technology to achieve non negative pressure water supply. It displays the operating status through a touch screen and is directly connected to the tap water pipeline network through a vacuum compensation system and a fully enclosed structure, overcoming the adverse effects on the pipeline network. As shown in the diagram:

By detecting the pressure in the pipeline network through a microcomputer and using negative pressure feedback to adjust the frequency of the frequency converter. Firstly, set the working pressure of the water point according to the actual situation, detect the actual pressure of the water outlet pipe and compare it with the set pressure. If the actual pressure is higher than the set pressure, reduce the frequency of the frequency converter, otherwise increase the frequency of the frequency converter. Industrial control microcomputers can detect pipeline pressure at any time, with fast calculation speed and instantaneous adjustment speed. Maintain the pressure of the pipeline network at the set value at all times.

In addition, as shown in the equipment composition diagram, the fully sealed structure and negative pressure feedback suppression system enable this equipment to be directly connected in series with tap water. Due to the superposition principle of the water pump operation, the equipment can fully utilize the original pressure of tap water, increasing theVariable frequency booster pump for water tank The energy-saving point. When the tap water pressure drops due to insufficient pressure, this equipment collects the vacuum degree and water level signals inside the steady flow compensator through the detection device in the vacuum suppressor and steady flow compensator. 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 this equipment does not have any impact on the urban pipeline network.

The intelligent era will promote the development of the integrated water supply equipment industry

China is a major producer of intelligent integrated water supply equipment. Currently, its main products such as non negative pressure water supply equipment, variable frequency constant pressure water supply equipment, and intelligent secondary water supply equipment have reached or are close to developed technical standards. Its production and research and development capabilities can also meet different market demands, and its price advantage is obvious, making it competitive in the market. With the continuous promotion of the construction process of intelligent integrated water supply equipment in China and the proposal of the corresponding incremental tiered electricity pricing reform model for residents, the requirements for energy-saving of related energy metering tools such as integrated water supply equipment have also increased.

Integrated smart water supply equipment is an important component of high-rise water supply and serves as the "terminal nerve" for achieving bidirectional interactive intelligent electricity usage. The gap between China's intelligent water supply technology and * level is relatively small in terms of technology, and coupled with its importance as an important component of low-carbon economy, it has stable high growth prospects. Compared with foreign countries, China's integrated water supply equipment has complete and standardized functions, such as tiered electricity pricing and load control, which can better meet the needs of intelligent integrated water supply equipment construction in China.

Integrated smart water supply equipmentCompared with ordinary water supply equipment:

Water supply method: If ordinary water supply equipment is directly connected in series to the tap water pipeline, there will be suction during operation, causing negative pressure in the tap water network. If used on a large scale, it will lead to water grabbing and cause chaos in the city's water supply. So people adopt the method of repairing stainless steel water tanks or setting up water tanks for secondary pressurized water supply. All tap water is put into the stainless steel water tank or water tank for secondary pressurized water supply.

Integrated Tank Pump Water TankSelection suggestion: Currently, our company producesIntegrated smart water supply equipmentThe precision and energy-saving effect of the control equipment are the same in both fixed and cyclic methods, and the disturbance to the pipeline pressure during the switching process is also very small. The differences are: fixed equipment has less investment, simple operation and maintenance, and fewer fault points, but the mechanical wear and tear of the pump is greater when switching between power frequency pumps, and the service life of each pump is uneven; The circulation method can reduce mechanical wear during pump switching, ensuring a uniform service life for each pump. However, the disadvantage is that the equipment investment is relatively high, as this method may cause current surges during pump switching, which can lead to adhesion of the contactor contact points over time. Therefore, the quality requirements for the contactor are high. If not selected properly, it may damage the frequency converter. We suggest that for systems with lower control power, both methods can be used, while for systems with higher control power, a fixed method is better.

Integrated Tank Pump Water TankInnovation:1In order to improve the reliability of the control system, we have specifically designed the reliability of the control circuit and software, such as programmable controllersPLCThe input and output terminals are both isolated by relays. If a controller is usedPLCThe output end of the contactor starts directly, but due to the large inductance of the contactor coil, it is easy to burn out after long-term operationPLCContact point, due to the controllerPLCThere is a control program in place, which can be difficult to replace due to malfunctions. Adopt measures for the controllerPLCThe isolation measures for input and output relays can improvePLCReliability due to the controllerPLCIt is the core of the entire control part, improvingPLCThe reliability of the whole machine is of great significance in improving its overall reliability.2Equipped with a water supply window(touch screen)In the control system equipment, photoelectric isolation measures are taken for communication between the touch screen and the frequency converter to ensure the safe operation and reliable communication of various electrical appliances.3In equipment equipped with a remote voice alarm system, when the device malfunctions and shuts down, it automatically dials the pre stored number to notify the equipment management personnel for timely maintenance to avoid affecting the user's water supply.4In large and medium-sized control systems, the cyclic soft start commonly used for equipment control has serious defects. During the conversion of water pumps from frequency conversion to power frequency, fatal electrical and mechanical impacts can be generated, which can endanger the safety of circuits and pipelines. Our company's developed impact free conversion technology can achieve impact free soft start and soft stop to avoid mechanical and electrical impacts. This technology is very important for application in large and medium-sized equipment.5In equipment with large fluctuations in water supply pressure requirements, variable voltage water supply can be used. The control system estimates the equipment flow rate based on the number of power frequency pumps turned on and the output frequency of the frequency converter, and compensates for the equipment outlet pressure to achieve further energy conservation6Our company can provide wired and wireless monitoring systems according to customer needs, transmitting the operating status of equipment to the monitoring center for real-time monitoring. The monitoring center can also control the operation of equipment in real time.7Our company's large-scale water plant monitoring system adoptsSCADThe control system, with centralized detection and decentralized control, has high flexibility and reliability.8Our company has successfully applied high-voltage frequency conversion to the water plant project and achieved good social benefits.Integrated Tank Pump Water TankWater supply method: Using vacuum suppression technology, the water supply equipment is directly connected in series with the tap water network, without generating negative pressure and without the need to build a water tank,Set up a water tank. Water supply quality: All pure tap water is put into the pool, and various dirt can easily enter the pool, seriously polluting the water source. Especially in summer, the water is prone to deterioration and odor, affecting the health of users.Integrated Tank Pump Water TankWater supply quality: Pure tap water is directly supplied to residents after being pressurized, and a steady flow compensator is usedSUS304Stainless steel material, sealed connection, no pollution, users can drink drinking water that meets hygiene standards.

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. 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.

Integrated smart water supply equipmentThe working principle of

Tap water enters the regulating 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 tap water can meet the requirements of water pressure and quantity,Variable frequency booster pump for water tankDirectly supply water to the water supply network through a bypass check valve; When the pressure of the tap water network cannot meet the water requirements, the system sends a pump start signal through a pressure sensor (or pressure controller, electric contact pressure gauge) to start the water pump operation. When the water pump is supplying water, if the water volume in the tap water pipe network is greater than the pump flow rate, the system maintains normal water supply. During peak water usage periods, if the water volume in the tap water pipe network is less than the pump flow rate, the water in the regulating tank can still be supplied as a supplementary water source. At this time, air enters the regulating tank through a vacuum eliminator, eliminating the negative pressure in the tap water pipe network. After the peak water usage period, the system returns to normal state. If the tap water supply is insufficient or the pipe network is shut down, causing the water level in the regulating tank to continuously decrease, the liquid level controller will give a pump shutdown signal to protect the pump unit. During nighttime and low flow water supply, small expansion tanks can be used to prevent the water pump from starting frequently.
