无泄漏泵制造成本要贵于常规泵，但其使用维护费用要比一般机械密封化工泵低得多。首先，无泄漏泵没有机封和轴承箱，泵轴xx封闭在屏蔽套（隔离套）内，变动密封为静密封，有效解决了泄漏和润滑问题；其次，无泄漏泵取消了联轴器，变硬连接为软连接，有效解决了振动及噪声问题；另外，无泄漏泵易损件明显减少（仅有轴承或口环），事故件也相对减少（仅有内、外磁转子）；{zh1}，无泄漏泵运行寿命延长，检修频次和时间大大减少，且检修劳动强度大大下降。根据2000～2001年度ABS装置统计结果，常规泵泄漏、故障等破坏率是无泄漏泵的6～8倍，机械密封化工泵更换易损件的费用是相似参数无泄漏泵的3～5倍。按照累积总费用计算，大约4～5年二者的数量基本相当。以上仅是从成本费用角度考虑，而机械密封化工泵外泄的物料往往也价格不菲，由环境污染、安全事故等原因带来的问题更多。无泄漏泵主要技术和使用时注意的问题 1无泄漏泵主要技术 1.1转子轴向力的调节与平衡 1.2冷却润滑措施 根据输送介质、工况的不同，屏蔽泵的循环方式主要有三种： （1）正循环 （2）逆循环 （3）外循环 1.3屏蔽套、隔离套及其间隙 1.4轴承与推力盘 1.5磁转子 1.6状态监控 2.无泄漏泵的应用前景 无泄漏泵虽然一次性投资较大，但无泄漏污染、节约物料，维护使用管理费用低，综合经济效益高，社会效益好。随着经济的发展、社会的进步，国家对企业在技术、环保等领域的要求越来越高，大力推广无泄漏泵技术前景良好。

Leak pump manufacturing costs, more expensive than conventional pumps, but its use in general maintenance costs than mechanical seal chemical pump is much lower. First of all, non-leaking pump mechanical seal and bearing no boxes, shaft completely closed in the shielding units (isolation units), the change in static sealing for the seal, an effective solution to the problem of leakage and lubrication; second, non-leaking pump abolished coupling, Connect to harden the soft connection, an effective solution to the vibration and noise problems; In addition, non-leaking pump wearing parts significantly reduced (only bearing or Sandy Bay), incident cases are relatively reduced (only inside and outside the magnetic rotor); final no leakage to extend the operational life of pumps, repair frequency and time greatly reduced, and maintenance labor intensity declined significantly. According to ABS unit from 2000 to 2001 results, conventional pump leakage, failure and other damage rate is no leakage of the pump 6 to 8 times, mechanical seal chemical pump replacement cost of wearing parts is similar to non-leaking pump parameter 3 to 5 times. In accordance with the cumulative total cost is approximately 4 to 5 years is roughly equal to the number of both. These are only from a cost point of view, while the mechanical seal chemical pump leaks often expensive materials, from environmental pollution and accidents caused more problems and other reasons. Leak pump the main technical and use attention A non-leak pump main technical 1.1 Regulation of the rotor axial force and balance Measures 1.2 Lubrication According to transmission medium, the different conditions, shielding the pump cycle there are three main methods: (1) is cyclic (2) reverse cycle (3) The outer circle 1.3 shielding cover, isolation units and the gap 1.4 Bearings and thrust plate 1.5 Magnetic Rotor 1.6 Status Monitoring 2. No leak pump application prospects Leak pump while a larger one-time investment, but no leakage of pollution, conservation of materials, use and management of maintenance and low cost, integrated economically efficient and socially good. With economic development, social progress, the state enterprises in technology, environmental protection and other fields have become increasingly demanding, and vigorously promote the good prospects for non-leak pump technology.
