1. Structural design breaks through the suction range limit
The biggest highlight of vertical long-shaft pump is its “submerged impeller” design, that is, the lower part of the pump body is deep into the water source, the impeller is in contact with the liquid surface, realizing natural water diversion and avoiding idling. Compared with the traditional horizontal pump due to the impeller is higher than the water level caused by the lack of suction problems, the design significantly improves the suction performance. The long shaft is connected by multiple couplings and supported by guide bearings, which not only guarantees the structural rigidity, but also improves the operational stability.
2. Adapt to high head and deep well conditions
Long shaft pumps are especially suitable for deep well water extraction, groundwater pumping and other conditions, supporting tens of meters or even hundreds of meters of head, and stable performance under complex geological conditions. High head water supply is realized through multi-stage impeller tandem structure, which can effectively cope with the needs of high-rise buildings, mountain water sources and other special scenarios. The diameter of the pump shaft is thickened, effectively resisting torsion and radial force, guaranteeing the precision of long-distance transmission.
3. Modular structure, easy to customize the design
Vertical long-shaft pump usually adopts modular structure design, pump head, guide shaft, impeller, pump cylinder and other parts can be flexibly configured according to user needs. Different lengths of pump shaft and guide bearing sections can be customized to adapt to different installation depths. This flexible design meets the individual requirements of different project sites, reduces the cost of secondary transformation and improves the matching efficiency of the project.
4. High-efficiency hydraulic model, improve operation efficiency
The pump adopts modern hydraulic model design, optimizes the impeller and guide vane channel structure, and controls energy consumption while maintaining large flow output. The smooth flow channel and symmetrical impeller reduce the hydraulic loss, realizing a significant increase in the efficiency of the whole machine. Compared with traditional pumps, it outputs a larger flow rate under the same power and consumes less energy per unit, which brings long-term energy-saving benefits to users.
5. Stable operation, adapt to continuous working conditions
Multi-point guide bearing structure design ensures stable operation of the long axis, avoiding vibration and deflection leading to equipment damage. Matching thrust bearings can withstand large axial force to ensure long-time continuous operation without failure. The bushing and bearing materials are mostly made of wear-resistant alloy or PTFE composite material, which improves the overall life and ability to adapt to high-frequency working conditions, and is widely used in water plants, industrial cooling and other scenarios that require long-time operation.
6. Anti-corrosion and anti-rust, adapt to complex media
The pump body can be made of cast iron, 304/316 stainless steel, copper alloy and other materials, adapting to clear water, light corrosion, salt-containing or sediment-containing water. The guide bearing and shaft sleeve adopt closed structure to avoid impurities entering the bearing system and prolong the service life. The whole machine is treated with anticorrosive spraying process, which still maintains stable performance in complex environments such as high humidity, salt spray, and underground shafts.
7. Flexible installation, adapting to the wellbore and the tank pool
Vertical long-shaft pumps can be installed vertically in the borehole, pump house or nullah tank, covering a small area, suitable for space-constrained scenes. The pump cylinder and motor base can be customized with well cover or concrete foundation, which is convenient for construction and installation. The guide shaft sections can be flexibly combined for easy transportation and lifting, greatly reducing the difficulty of on-site installation and construction period.
8. Simple maintenance, reduce operation and maintenance costs
The pump structure is clearly segmented, and the pump head, guide shaft and impeller can be disassembled separately for maintenance, saving manpower and downtime. The guide bearing is equipped with lubrication channel, which is convenient for maintenance. Part of the model can be equipped with automatic lubrication system, realizing long-term operation under unattended condition, reducing labor cost and improving operation reliability.
9.Support intelligent control system
It supports remote monitoring, real-time parameter feedback, running status alarm and other functions, and can be integrated into building BMS system or industrial control platform. Through the PLC control cabinet linkage motor start and stop, frequency adjustment and other actions to improve the level of operational intelligence. Part of the system can realize cloud monitoring and remote troubleshooting, helping to upgrade the digital fire protection system.
10. Widely used, stable reputation
Vertical long-shaft pumps are widely used in high-rise building water supply, municipal engineering, water plants, metallurgy, electric power, petrochemical and other industries, and their stable performance and reliable structural design have been widely recognized in the market. Whether it is harsh working conditions or long time running tasks, the pump can provide strong technical support and win the praise of customers.
With its unique structural form and high stability, the vertical long-shaft pump provides an ideal solution for high suction range conditions. Its modularity, high efficiency, corrosion resistance, easy maintenance and other advantages make it highly practical value in all kinds of fire fighting, water supply and industrial systems. In the future, with the upgrading of intelligent fire fighting system, this type of pump will become one of the preferred core power equipment.
