DG series boiler feed Industrial water pump

Industry knowledge

What are the advantages of DG series boiler feed water pumps in terms of energy efficiency?

High efficiency and energy saving: The DG series boiler feed water pump adopts the high-efficiency and energy-saving hydraulic model recommended by the country. This design allows the pump to more efficiently convert electrical energy or thermal energy into the kinetic energy and potential energy of the fluid during operation, thus improving the energy efficiency of the pump.
Wide performance range: DG series boiler feed water pumps have a wide performance range and can adapt to different flow and head requirements. This allows the pump to adjust operating parameters according to actual working conditions during operation, avoiding excessive energy consumption and further improving energy efficiency.
Safe and stable operation: The rotor part of the DG series boiler feed water pump adopts balancing measures such as a balance plate, which can effectively balance the axial force and make the pump more stable during operation. This smooth operation helps reduce energy consumption and wear, extending the life of the pump.
Low noise: DG series boiler feed water pumps pay attention to reducing noise during the design and manufacturing process, and use components such as low-noise bearings and seals. This allows the pump to operate with lower noise, improves the working environment and reduces energy consumption due to noise.
Easy installation and maintenance: DG series boiler feed water pumps adopt a modular design, making the installation and maintenance of the pump more convenient. This design helps reduce installation and repair time and maintenance costs while also improving pump operating efficiency.

What measures have the manufacturers of DG series boiler feed water industrial water pumps taken to reduce the noise and vibration generated by the DG series boiler feed water pumps during operation?

Optimize mechanical structure design:
Shaft design: increase the number of drive shaft support bearings, reduce the support spacing, reduce the shaft length within an appropriate range, appropriately increase the diameter of the shaft, and increase the stiffness of the shaft. At the same time, avoid the relationship between the pump shaft speed and the natural vibration frequency of the pump rotor to be close to or an integer multiple to reduce vibration caused by resonance.
Selection of sliding bearings: In specific applications (such as chemical pumps such as liquid hydrocarbons), materials with good self-lubricating properties such as polytetrafluoroethylene are selected as sliding bearing materials. In deep well hot water pumps, the diversion bushing may be filled with polytetrafluoroethylene, graphite and copper powder, and its structure may be reasonably designed to improve fixation reliability.
Design of impeller and sealing ring: Friction material with small friction coefficient, such as M20lK graphite material-steel, is used at the impeller sealing ring and pump body sealing ring to reduce friction and vibration.
Improve manufacturing and assembly quality:
Improve the manufacturing quality of the shaft and prevent mass eccentricity and excessive geometric tolerance.
During the assembly process, pay attention to the alignment of the coupling to avoid problems such as damage to the elastic block of the coupling and too small coupling clearance.
Choose high-quality bearings, such as SKF imported bearings, to avoid vibration caused by bearing quality problems.
Use shock absorption and sound insulation measures:
Install rubber shock-absorbing pads or linkage supports and other shock-absorbing measures on the support frame of the boiler feed water pump to reduce the impact of vibration on the equipment and the surrounding environment.
Install a soundproof cover or soundproofing material around the boiler feed water pump to reduce the spread of noise.
Reasonable installation and debugging:
Ensure that the installation height of the water pump meets the design requirements to avoid vibration and noise problems caused by insufficient installation height.
Warm the pump before starting the machine to avoid vibration and noise caused by temperature differences.
Applications of intelligent control systems:
Through the intelligent control system, automatic control of the boiler feed water pump is realized, such as controlling the start and stop of the water pump, speed adjustment, etc., to reduce noise and vibration.
The comprehensive application of the above measures can effectively reduce the noise and vibration generated by the DG series boiler feed water pump during operation and improve the operating efficiency and stability of the equipment.
