Product Description Direct-connected Water Supply EquipmentProduct Overview                        The direct-connected water supply equipment is a new type of water supply equipment developed and manufactured by Shanghai Dongfang Pump Industry (Group) Co., Ltd. Adhering to the concepts of technology, environmental protection, energy conservation, and safety, and featuring specialization, refinement, distinctiveness, and innovation, it makes full use of new-generation information technologies such as big data, artificial intelligence, cloud computing, and edge computing. Relying on strong production capabilities, this equipment has remarkable characteristics including high integration, energy conservation and environmental protection, excellent performance, compact structure, and quick installation.Application Fields                             Pressure boosting for high-rise and multi-storey buildingsResidential areas with insufficient pressure at the end of the water supply networkImproving the quality and efficiency of rural drinking waterResidential areas with old pumping stations undergoing renovationResidential areas without pumping stationsWater supply in scenic areasEmergency temporary water supply Product Features                       Protection AssuranceThe enclosure is made of SUS304 material with a P - shaped rain - proof and sun - proof design (IP55). The exterior is designed with a service life of 50 years.Safety and HygieneThe food - grade stainless - steel flow - through body operates in a fully - enclosed manner, completely eliminating secondary pollution.Energy Conservation and Environmental ProtectionUsing pressure - boosting technology with water - squeezing, full - variable control, it makes full use of the pressure in the municipal water supply network, is equipped with air - squeezing pressure, and reduces pressure for small - flow, thus lowering energy consumption.Convenient OperationOne - button start and stop, with a transparent view of the working status. It is designed based on ergonomics, with a compact structure and an aesthetically pleasing exterior.Unattended OperationAutomatic pump switching, balanced operation, automatic inspection, stop when there is no water, and automatic restart when power is restored.Intelligent SecurityRemote monitoring, temperature and humidity adjustment, water leakage detection, noise detection, and fault alarm.Quick InstallationModular detachable structure, pre - fabricated in the factory and delivered as a whole. Just connect the inlet and outlet water pipes and power on to operate.Noise ReductionThree - layer noise reduction with sound - absorbing panels, integral sound - absorbing covers, and stainless - steel exteriors, which is 10dB or more lower than conventional products.Reliable ServiceThe company has 16 subsidiaries, 26 branch offices, over 200 business offices, and provides 7×24 - hour after - sales service. The one - time commissioning qualification rate is ≥98%.Application Conditions                             Water supply flow rate: ≤ 100 cubic meters per hourWater supply pressure: ≤ 1.6 megapascalsSingle - pump power: ≤ 11 kilowattsNumber of water pumps: 2 to 3 units (including one standby pump)Control accuracy: ≤ 0.01 megapascalsAmbient temperature: - 40oC to 55oCRelative humidity: 20% to 90% (for the electrical control part)Power supply: Three - phase five - wire system (TN - S), AC380V ± 20V, 50HzAltitude: ≤ 1000 metersEnvironmental quality: Free of flammable, explosive, corrosive substances, and conductive dustModel Definition BW - Z(II) Component Configuration:A.A: Imported components. : Number of frequency converters.B.B: Domestic components. : Number of frequency converters.Other Option Requirements:No mark: Standard configuration with no additional requirements.D: Electric heating.K: Industrial air - conditioning.Pump Series:No mark: DFCL series.T: Other pump types.Number of Water Pumps: 2 - 3 (including 1 standby pump).Single - pump Power (kW):Equipment Head (m):Equipment Flow Rate (m3/h):Direct - connected type:Pipe network superposition (non - negative pressure) water supply equipment: Example: BW - Z(II)32/58-5.5-3-A3 indicates a direct - connected water supply equipment with an equipment flow rate of 32 m3/h, an equipment head of 58 m, 3 DFCL water pumps, a single - pump power of 5.5 kW, imported main components, and full - frequency conversion control.Working principle                            Serial NumberNameSerial NumberNameSerial NumberNameSerial NumberName1Butterfly valve2Flexible rubber joint3Water pump4Check valve5Pressure transmitter6Electric contact pressure gauge7Control cabinet8Air pressure tank9Lighting lamp10Temperature and humidity sensor (Optional)11Water immersion sensor (Optional)12Smoke sensor (Optional)13Noise sensor (Optional)14Industrial air conditioner (Optional)15Flowmeter (Optional, installed outside the box)16Filter (Optional, installed outside the box)17Exhaust valve      Function Configuration Table                           Serial NumberCategoryNameFunction Description1EnclosureOutdoor - type enclosureTwo materials are available, SUS304 and spray - plastic carbon steel.
