MFY 型双壳体液氯磁力泵

MFY Magnetic Driven Submerged Liquid Chlorine Pump 

  MFY型双壳体液氯磁力泵是一种液下式磁力驱动筒袋泵，广泛应用于氯碱行业对液氯的加压输送、包装及处理。采用双层隔离套保护，不需要氮气隔离密封，无氮气和氯气损耗，不会产生混合尾气，内部可实现自动排气，弥补了普通液氯液下泵在生产中存在的安全隐患，满足液氯连续、高压输送和灌装的需要。
MFY is a submerged magnetic driven barrel pump, extensively used in pressurizing, conveying, packaging and disposing of liquid chlorine in chlor-alkali industry. Double-layer spacer sleeve protection is adopted, without the need of nitrogen isolation and sealing, no nitrogen and chlorine loss, and it produces no mixed tail gas; automatic vent can be realized within the pump, avoiding the safety hidden perils in the production with ordinary submerged pump for liquid chlorine, and fully meeting the needs in continuous conveying and filling of liquid chlorine under high pressure.

结构说明 Description of structure
液下式磁力驱动多级离心泵，轴向吸入、径向剖分。
A multi-stage magnetic driven submerged centrifugal pump, with axial suction and radial splitting.

立式筒袋式双层壳体结构，内层为节段式，泵的外壳承受入口压力，外壳按压力容器设计，外壳的长度以及泵的插入深度取决于装置汽蚀余量要求，也可以直接安装在储存介质的容器上，此时不需要安装外壳，容器即成为泵的外壳。
It is in vertical barrel double-volute structure, the inner layer is sectional, and the outer shell withstands the suction pressure, its length and pump insertion depth depend on the NPSH requirement of the unit, it can also be directly mounted on the vessel storing the media, in this case, outer shell is not required, and the vessel can serve as the outer shell of the pump.

特殊的首级叶轮设计技术，优秀的诱导轮技术，低转速、低汽蚀余量、高抗汽蚀性能泵的气蚀余量NPSHr=0.5-0.8m。
Special first-stage impeller design technique and excellent inducing wheel technique, low speed, low NPSH and high resistance to cavitation.

轴向力利用流体力学的平衡鼓技术自动平衡，充分保证了泵的正常启停和滑动轴承的使用寿命。
The axial force is automatically balanced with the balance drum technology in hydrodynamics, fully ensuring the normal start and stop of the pump and the service life of sliding bearings.
通过磁性联轴器驱动，所有密封点均由密封垫实现静密封，无须干气作为密封阻隔气，没有氮气和氯气损耗，不必安装卸压管及安全阀，不必配用氮气中间罐及相应管路，做到无泄漏。
It is driven via magnetic coupling, static sealing is realized with sealing packs at all points, no need for dry gas as sealing gas, therefore there is no nitrogen or chlorine loss, and it is not necessary to provide pressure relief pump and relief valve, or intermediate nitrogen tank and associated piping, completely avoiding leakage.

隔离套材料选用高强度、高阻抗的材料，在旋转磁场中极大的降低了磁涡流的产生，磁涡流损失小，磁传动效率高，对介质的温升影响小。
Spacer is made of materials with high strength and high impedance, greatly reducing the magnetic vortex in the rotating magnetic field, therefore low magnetic vortex loss, high magnetic driving efficiency and small impact to the temperature rise of media.

采用双层隔离套结构，双重静密封，实现双重保护，并配置液体泄漏检测仪表，可实现泄漏报警，更加安全可靠。
Double layer spacer structure is used with dual static sealing, realizing dual protection, and liquid leakage detection instrument is provided, to realize leakage alarm, for increased safety and reliability.

的泵的内部循环系统和泵与储罐之间的气相平衡系统，让整个泵组件在边界条件下都是安全的。
Unique internal circulating system of the pump and the gas-phase balance system between the pump and tank, so that the whole pump is safe under boundary conditions.

一般安装于系统的位，当需要排除液氯时也比较方便和迅速，防止了液氯中NCL3聚集的安全风险。
Normally it is installed at the lowest position of the system, and when it is necessary to remove liquid chlorine, it can be done conveniently and quickly.

泵的内置滑动轴承选用高纯度的碳化硅陶瓷复合材料，具有较高的强度、韧性及耐磨性和良好的自润滑性能，可适应液氯在气液混合态下近似于干运转的工况。
The built-in sliding bearings in the pump are made of high-purity silicon carbide ceramics composite material, featuring high strength, tenacity, wearing resistance and good self-lubrication performance, able to meet the nearly dry operation condition for liquid chlorine in the mixed status of gas and liquid.

泵的入口尺寸采用加大设计，均在DN100以上，以降低泵与液氯储罐之间接管的阻力损失。
配置变频调速电机对泵的流量及出口压力进行调节，以给定的压力为基点进行调整，压力波动小，控制可靠稳定。不必安装卸压管及安全阀。不必配用氮气中间罐及相应管路。
