产品优势
VISO系列是一款真正满足客户全方面需求的产品。
VISO series is a kind of product that can really meet the needs of customers.
适合各种应用场合：所有型号能同时被应用在50Hz和60Hz情况下运行。
Suitable for various applications: All models can be used in case of 50Hz and 60Hz operation.
高标准化 High standardization
高标准化设计的VISO水泵，极大地提高了零件的互换性，降低需要备品备件的种类和数量，更便于检修管理，最大幅度降低用户日常维护成本。
Designed in high standardized VISO pump greatly improve the interchangeability of parts, greatly reduce the type and quantity of spare parts for customers, easier maintenance and management, directly save the costs of usual maintenance for you.
维护简单 Easy to maintain
VISO产品采用目前最成熟的后拉式结构，拆装维护简单。可以做到拆卸时不动管路系统、泵壳和电机，安装后无须重新对中，大大减少维修工作量。而且，VISO采用NSK免维护轴承，在正常使用情况下，可以终身免维护，无需为定期添加润滑脂而烦恼，大量节约日常维护时间。
VISO products adopt the most mature rear entry structure, easy to dismounting and maintain. Demolition can be done without moving pipeline system, pump case and electrical machine, after install, need not center again, greatly reduce maintenance workload. And VISO adopt Maintenance-free bearings with NSK, in normal use, it can be lifelong maintenance free, do not worry about add grease regularly, save plenty of daily maintain time.
技术特征
闭式结构叶轮：采用优秀的水力模型，效率高，抗汽蚀性能强。
Closed structure impeller: adopt excellent hydraulic mode efficient, highly resistant to capitation erosion.
单端面机械密封：结构简单，密封性能好，使用寿命长，维护方便（符合ISO3069标准）。
Single mechanical seal: simple in structure, good sealing performance, long life, easy to maintain (meet the criterion of ISO3069).
重型不锈钢轴：高速运转时刚性强，不易损坏，坚实耐用。
Heavy stainless steel shaft: when high-speed running rigidity is strong, uneasy to damage, solid and durable.
轴向力：采用平衡孔平衡轴向力，轴承受力小，有效的提高了轴承寿命。
Axial force: adopt balance hole to balance axial force, bearing’s capacity is small, effectively improve the bearing life.
叶轮平衡：叶轮按ISO1940-2000，G6.3级校准平衡，运行时振动小，大大提高了轴承和机封的使用寿命。严格的质量保证体系，先进的装配工艺，也为VANO产品稳定的性能提供了坚实的保障。
Impeller balance: impeller meets the criterion of ISO1940-2000, G6.3-level to calibration balance, little vibration, greatly improve the life of bearing and mechanical seal. Strict quality guarantee system, advanced assemble technique, also supply solid safeguard for the steady performance of VANO products.
轴 Shaft
加长轴的设计可以减小偏差，锥形轴的设计可以确保轴在运转状态下的可靠锁紧，键联结，双螺母锁紧，同时也方便维修时叶轮的拆卸。轴的材质设计也可以按照需要更改。
The design of lengthening shaft can reduce the deviation; the design of conical shaft can ensure that shaft is drop locked when running. key joint, double nut is locked, and it is easy to dismantle shaft when service. The material design of shaft also can be changed as needed.
轴封 Shaft seal
VISO系列的轴封的选择范围很广。如果介质的温度高或含沙量高，对密封件有特殊的要求，请及时VANO。
The range of choice of VISO series shaft seal is wide. Standard materials include graphite, ceramics, and Fluor rubber. If medium temperature is high or sand content is high, the seals have special requirement, please contact with the authorized distributor of VANO.
