DG boiler feed water pump, also known as the feeding pump is a horizontal centrifugal pump used to supply water to steam generators such as boilers. Currently, all boiler feeding pumps are centrifugal pumps, used in fuel and nuclear power plants. DG series is a common horizontal multistage centrifugal pump with a flow rate typically ranging from 10 to 500 m³/h and a head coverage of 100 to 2000 meters, operating at temperatures ≤160°C. This pump model features cast steel or stainless- steel flow components and possesses characteristics such as high efficiency and low net positive suction head. Boiler feed pumps must comply with standards like GB/T 5657 and API 610, along with specialized technical specifications such as JB/T 6614-2025. Performance range (design point) Flow rate Q: 3.75~720 m³/h Head H: 476~985 m Structural characteristics: DG type pump is a horizontal, single-suction, multi-stage segmented centrifugal pump. Both the inlet and outlet of the pump are vertically upward. The tightening bolts connect the suction section, middle section, and discharge section into a single unit. The pump rotor consists of components such as the impeller and balance disk mounted on the shaft. The entire rotor is supported by sliding bearings at both ends of the pump shaft. The bearings are lubricated with oil and cooled by circulating cold water. The axial force of the rotor is balanced by the balance disk. The shaft seal adopts either packing or mechanical sealing. Sealing glands are installed at both ends of the shaft, containing soft packing or mechanical seals. Pressurized water is directed into the sealing glands to provide water sealing and cooling functions. A replaceable bushing is fitted at the shaft seal to protect the pump shaft. The pump is directly driven by the motor through an elastic coupling, and from the motor end, the pump rotates clockwise. The boiler feeding water pump is a horizontal, two-end supported, radially split, radial-flow centrifugal pump used to provide feedwater equivalent to steam discharge for steam generators (such as boilers or nuclear reactors). During the operation of the boiler feedwater pump, it is necessary to ensure a minimum flow rate to prevent damage to the pump caused by vaporization or cavitation due to the increase in medium temperature under low flow conditions. This is usually achieved by installing a minimum flow valve (automatic recirculation valve). The pump can only operate within the specified parameters; It is not allowed to operate for a long time when the outlet valve is closed or the opening is very small; Cannot close the suction valve for operation; The conveying medium must not contain air or gas; Materials that cannot transport particles on the conveyor belt; Before starting, a check is required. Before starting the pump, check the bolts, pipelines, instruments, valves, oil level, and motor direction; Open the suction valve and close the outlet valve when starting, fill the pump with liquid, start the motor, and slowly open the outlet valve after normal operation. During the operation of the pump, it is necessary to regularly monitor the pressure, flow rate, temperature, vibration, and lubrication conditions. The temperature rise of the bearing should not exceed 35 ℃ above the ambient temperature, and the maximum temperature should not exceed 75 ℃. It is necessary to check whether there is balancing liquid flowing out of the balancing device (connected to the suction section through the balancing water pipe). When stopping the pump, the outlet valve should be closed to the minimum flow rate first, then the motor should be stopped, and finally the outlet valve should be closed. After the pump stops steadily, the suction valve should be closed. It is strictly prohibited to close the suction valve first.

Metal or plastic magnetic pump for refrigerant Magnetic pump is mainly composed of pump head (impeller, pump body), outer magnetic steel (active rotor), inner magnetic steel (passive rotor), and isolation sleeve. The electric motor drives the outer magnet to rotate, and because of the effect of the magnetic field, the inner magnet rotates synchronously. Because the inner magnet and impeller are integrated, the impeller also rotates together with the inner magnet to pump liquid. A static isolation/spacer sleeve made of corrosion-resistant and high-strength engineering plastics, stainless steel, and other materials is installed between outer magnetic steel or inner magnetic steel. The conveyed medium is enclosed within the isolation sleeve, thus completely solving the problems of running, emitting, dripping, and leaking that cannot be solved by dynamic seals. The wide application of magnetic pumps in the refrigeration industry 1、 Refrigerant pump The refrigerant pump is an important component of the refrigeration system, and the magnetic pump can effectively meet the pumping needs of the refrigerant. Due to the use of a leak free sealing structure in the magnetic pump, refrigerant leakage is avoided, and the hassle of frequently replacing seals in traditional gas turbine water pumps or mechanical seal pumps is also eliminated. Therefore, the application of magnetic pumps in refrigeration systems is becoming increasingly widespread. 2、 Refrigerated oil circulation pump The refrigeration oil circulation pump is an important component of the refrigeration system, which separates the oil in the liquid refrigerant to avoid affecting the refrigeration effect. Magnetic pumps can meet such specialized applications. Using magnetic pumps can greatly reduce the occupied area of pump rooms, while also achieving precise flow and pressure control. 3、 Cooling water pump Cooling water pumps are mainly used in the cooling circulation water circuit of refrigeration systems. Traditional cooling water pumps usually adopt mechanical seal structures, and problems such as corrosion, corrosion, and leakage of refrigerant during operation can lead to a decrease in pump performance and increase maintenance difficulty. The magnetic pump adopts a leak free sealing structure design, which can avoid such problems and greatly improve performance.

Centrifugal Condensate water pump is a special type of centrifugal pump designed for transporting high-temperature condensate water (such as turbine condensate water); The core difference between the two lies in their adaptability to working conditions, structural materials, and sealing design, rather than their working principles. Different uses: Ordinary centrifugal pumps are used for general liquids (water, oil, chemical media, etc. ); Condensed centrifugal water pumps are specialized for high-temperature (usually 80-120 ℃), clean, low-pressure condensed water or saturated water, commonly used in power plants and heating systems. Structural strengthening: Condenser pumps are often made of heat-resistant materials (such as cast steel and stainless steel), and the design of the suction chamber is optimized (such as raising the suction port and installing a suction valve) to enhance their anti cavitation ability; The structure of ordinary centrifugal pumps is more universal, and the material depends on the medium (such as cast iron, carbon steel). Sealing and bearings: Condenser pumps are often equipped with packing seals or mechanical seals+cooling water flushing to cope with high temperature and low cavitation allowance conditions; There are various sealing forms for ordinary centrifugal pumps, but high temperature/low NPSH optimization is not necessary. Installation requirements: The condenser pump has higher requirements for shaft alignment accuracy (≤ 0.1mm) and pipeline support, as it is often directly connected to the turbine and sensitive to vibration; The installation standards for ordinary centrifugal pumps are relatively loose. Classification: Condensed centrifugal water pumps belong to the subcategory of centrifugal pumps, which can be single-stage or multi-stage according to the number of impeller stages. However, "condensing pumps" do not constitute an independent working principle classification - all condensing pumps are based on centrifugal force infusion.
