The DFK S - WG series control cabinets are an important part of the pipe network superposition (non - negative pressure) water supply equipment, specially designed for the pipe network superposition (non - negative pressure) water supply equipment produced by our company. They can be used in combination with the BW - G(I) and BW - G(I)B series of pipe network (non - negative pressure) superposition water supply equipment. They can also be matched with the BW - G(II)P and BW - G(II)BP pipe network superposition (non - negative pressure) water supply equipment, and are suitable for the BW - Z(I) and BW - Z(I)B direct - connection (non - negative pressure) water supply systems.
This series of control cabinets utilize the currently leading AC variable - frequency speed - regulation and microcomputer control technologies. They are a new - generation mechatronic energy - saving control equipment that combines variable - frequency speed regulators with programmable logic controllers (PLCs), human - machine interfaces, pressure signal detection devices, protection devices, etc.
Model Definition
Examples:
Model: DFK;Code: S7.5 - 2VI - CT - WG - BF - A2. This indicates that the control cabinet is part of the standard series for pipe network superposition (non - negative pressure) water supply equipment. It controls two 7.5KW domestic water supply main pumps. Both the main pumps and auxiliary pumps adopt a full variable - frequency one - to - one control mode. It has a Type A imported brand configuration with 2 backpack - type frequency converters, and is also equipped with a PLC and a human - machine interface. The control cabinet uses pressure as the control parameter (i.e., constant pressure with variable flow). It is a dedicated control cabinet for the double - tank non - negative pressure equipment in the BW - G(I) and BW - G(I)BP series of pipe network superposition (non - negative pressure) water supply equipment.
Model: DFK;Code: S7.5 - 2VI - CT - WG(II) - BF - A2. This means the control cabinet belongs to the standard series for pipe network superposition (non - negative pressure) water supply equipment. It controls two 7.5kW domestic water supply main pumps. With a Type A imported brand configuration, it has 2 backpack - type frequency converters, along with a PLC and a human - machine interface. The control cabinet takes pressure as the control parameter (i.e., constant pressure with variable flow). It is a dedicated control cabinet for the double - tank non - negative pressure equipment in the BW - G(II)P and BW - G(II)BP series of pipe network superposition (non - negative pressure) water supply equipment. The BF backpack - type frequency converters are only applicable to Type A configurations, and the number of frequency converters should be equal to the number of pumps. The A1 configuration is only suitable for one - to - one control scenarios.
Model: DFK;Code: S7.5 - 2VI - CT - Z(I) - ZT - A2. This shows that the control cabinet is from the standard series for pipe network superposition (non - negative pressure) water supply equipment. It controls two 7.5kW domestic water supply main pumps. The main pumps adopt a full variable - frequency one - to - one control mode. It has a Type A imported brand configuration with 2 independently - installed imported brand frequency converters, and is equipped with a PLC and a human - machine interface. The control cabinet uses pressure as the control parameter (i.e., constant pressure with variable flow). It is a dedicated control cabinet for the direct - connection equipment in the BW - Z(I) and BW - Z(I)B series of pipe network superposition (non - negative pressure) water supply equipment.
Model: DFK;Code: S7.5 - 2VI - CT - WG - ZT - T. This indicates that the control cabinet is part of the standard series for pipe network superposition (non - negative pressure) water supply equipment. It controls two 7.5kW domestic water supply main pumps. The main pumps adopt a full variable - frequency one - to - one control mode. With a Type T configuration for brand customization and control function customization, it has 2 independently - installed imported brand frequency converters, along with a PLC and a human - machine interface. The control cabinet uses pressure as the control parameter (i.e., constant pressure with variable flow). It is a dedicated control cabinet for the tank - type pipe network (non - negative pressure) variable - frequency water supply equipment in the BW - G(I) and BW - G(I)B series of pipe network superposition (non - negative pressure) water supply equipment.
