Product Description Product Overview                        With the development and progress of social, economic, and technological conditions, and the gradual improvement of people's living standards, water supply safety has received increasing attention. After years of design and research and development, Shanghai Dongfang Pump Industry (Group) has successfully developed a safe and efficient water supply unit with intelligent, information - based, and standardized features. By comprehensively utilizing information technologies such as the Internet of Things, wired sensing or virtual sensing, and AR (Augmented Reality), it effectively integrates a series of systems, including intelligent perception of the operating status of the water supply unit, intelligent data collection and transmission, system alarm linkage, and intelligent diagnosis of unit faults. This enhances the safety management level and efficient operation status of water supply equipment, and achieves dynamic perception, intelligent assessment, and safety protection, providing users with systematic solutions throughout the product's entire life cycle.Working Environment                        Power supply voltage: 380V×(100±10%), three - phase five - wire system;Ambient temperature: +4°C to +40°C (corresponding measures must be taken if it exceeds this range);Relative air humidity: 20% - 90% (no condensation at 20°C);Installation location: A place without conductive dust, gases that can corrode metals and damage insulation, and free from explosion hazards;Altitude not exceeding 1000m. When it exceeds, the control components should be adjusted accordingly.Scope of Application                     The pressurized water supply equipment is widely applicable to water supply in buildings with good municipal conditions;Applicable to residential communities, public buildings, schools, hospitals, factories, renovation of old pump houses, etc.Model Definition                           Description of Working Principle                         Serial NumberAccessory NameSerial NumberAccessory NameSerial NumberAccessory NameSerial NumberAccessory Name1Control Cabinet2Bidirectional Compensation Switching Device3Bidirectional Compensation Tank4Digital Vacuum Suppressor5Steady Flow Tank9Butterfly Valve10Check Valve11Water Pump (Optional Integrated High - efficiency Synchronous Motor)12Pressure Sensor13Overpressure ProtectionSmall Flow Pressure - maintaining Tank   Optional Accessories (Except for UV Disinfector): Customers should install them reasonably according to the actual installation location of the equipment and the pump room (Installation accessories are not provided).6UV Disinfector (Optional, Installed by the Manufacturer)7Backflow Preventer (Optional, Installed by Customers)8Filter (Optional, Installed by Customers)  The BW - G(III) water supply equipment utilizes the existing pressure of the municipal pipe network to supply water with superimposed pressure without affecting surrounding users (supplying water in proportion to the inflow), achieving energy - saving. The water from the municipal pipe network is directly connected to the inlet of the equipment, and the outlet of the equipment is linked to the user's pipe network. The entire system is isolated from the outside. Meanwhile, the equipment meets performance standards, maintains a constant water supply pressure, runs stably without leakage, thus conserving water resources and ensuring the absolute safety and pollution - free nature of users' water supply.The equipment mainly consists of a bidirectional compensation tank, a pneumatic tank, a disinfection device (optional), a pressurized water pump unit, a bidirectional compensation mechanism, a pressure - stabilizing system, a digital full - variable - frequency control system, and inlet and outlet water pressure detection.During low - water - consumption periods, when the water supply and pressure from the municipal pipe network fully meet the requirements of the user's pipe network, the control system puts the water pumps into a sleep energy - saving state or a short - term low - speed operation state for a single pump to replenish pressure. The bidirectional compensation tank can maintain pressure for small - flow water supply.During high - water - consumption periods, when the pressure of the municipal pipe network is insufficient but the water supply can meet users' needs, the pressure of the pipe network is directly superimposed on the inlet of the water pumps. The control system adjusts the rotational speed of the water pumps and the number of pumps in operation according to users' water consumption. The bidirectional compensation tank briefly supplements the insufficient water supply in the pipe network to ensure a constant - pressure water supply to users.When users' water demand increases, causing the water supply in the pipe network to be less than the demand, and the inlet water pressure is lower than the set value, or there is an instantaneous pressure fluctuation, the bidirectional compensation tank automatically compensates for the municipal inlet water through the bidirectional compensator. Meanwhile, the control system monitors the inlet water pressure of the pipe network in real - time. Through computer calculus and fuzzy control, it promptly reduces the rotational speed of the water pumps and controls the water supply flow to ensure that the water supply equipment does not create negative pressure suction on the municipal pipe network and does not stop supplying water due to insufficient water supply.As the pressure of the municipal pipe network gradually drops to the pre - set protection pressure value, the microcomputer control system also gradually reduces the rotational speed of the water pumps until the system automatically stops operating. When the pressure of the municipal pipe network recovers to an allowable level, the equipment automatically resumes operation.Product FeaturesEnsuring Safe and Hygienic Water SupplyStrong Regulating and Energy - storing Ability: High - sensitivity, high - backpressure bidirectional automatic compensation device. When the pressure of the municipal pipe network is insufficient, the water stored in the bidirectional compensation tank can be fully supplied to the user's pipe network system, suppressing the generation of negative pressure. When the municipal pressure is sufficient, it stabilizes the outlet water pressure and supplies small - flow water.Fully Enclosed Operation: The equipment operates in a fully enclosed manner, free from leakage and secondary pollution.Full - coverage Design: Compact structure with an aesthetically pleasing appearance.Control Cabinet Protection: The control cabinet shell has an IP55 protection level. A dehumidification device is optional, enabling it to withstand harsh environments such as humidity and water splashes.Overpressure Protection: The equipment is equipped with an overpressure protection device. It automatically shuts down in case of overpressure or pipe bursts. A water immersion sensor (optional) monitors water accumulation in the pump room and triggers automatic shutdown and alarms, protecting the pipeline and water - use safety.Integrated UV Disinfector (Optional): With integrated UV disinfection (optional) and stainless - steel SUS304 food - grade pipes, it ensures no water pollution.High - efficiency Energy - savingWith virtual sensing terminal constant - pressure variable - frequency control (optional), the energy - saving rate is about 74% at 50% flow rate (compared to 67% in general cases), which is 32% more energy - saving than near - pump constant - pressure control mode. (The operation range is from point DD to point LL).The reasonable design of the tank structure effectively reduces the number of pump starts, saving energy consumption.The BW - G(II)BP model is equipped with an IE5 - efficiency motor, which is highly energy - efficient.Ensure Stable Water Supply PressureThe BW - G(III)BP adopts variable - frequency one - to - one drive. The water pressure is stable and the failure rate is low. The pumps are driven by a one - to - one variable - frequency mode, eliminating the hydraulic shock generated during the switching of multiple pumps in the traditional one - to - multiple drive. The pumps start and stop softly, operate smoothly, and maintain stable water supply pressure. Meanwhile, the variable - frequency drives can be used as backups for each other, resulting in a low failure rate.Reasonable tank structure design: The equipment is equipped with tanks with different functions, which can stabilize flow, maintain pressure, provide bidirectional compensation, and eliminate water hammer effects, ensuring stable water supply and a comfortable water - using experience.Ensure Stable Product QualityThe pictures show various manufacturing equipment and components.Flexible manufacturing is carried out using robots and numerically - controlled equipment, which surpasses traditional welding, cutting, and bending techniques, ensuring the reliability and stability of product quality.Production Plant                      Main Processing Equipment                  Electrophoresis and coating line                Company Profile
