宁波安全，准确剂量150万名市民

Overview

The situation

中国的城市宁波建造了第一座现代化污水处理厂于2007年在山山坡上募集近400万在浙江省宁波市东钱湖水厂将供应水，约占全市的三分之一这个市区人口。
姜压溶worked with the plant to secure a proper pump supply. She is general manager of Hangzhou Jijie Environment Protection Technology Company. Nearly a decade later, she visits the plant, walking along its settling tanks and under a sign that says, "Building a harmonious environment" in Chinese characters. On a rock face over a tunnel behind the plant, the word "water" is painted in several styles.

"Ningbo Dongqian Lake water plant is one of my classic customers and one of the key successful cases in Zhejiang water plants," she says. She points out that the plant was able to successfully avoid problems in one of the most troublesome applications at water treatment facilities: the pumping of sodium hypochlorite.

此挥发性化合物，用作消毒剂，具有高pH水平和是危险的，如果它与人类接触或在高浓度的环境。找到合适的泵技术是至关重要的姜压榕说18luck手机客户端下载。“在中国市场的正常计量泵无法避18luck手机客户端下载免的渗漏问题，”她说。这家工厂必须是这个城市的居民和工厂的工人的安全。

解决方案

姜雅嵘建议格兰富DME数字式计量泵。18luck手机客户端下载十年后，二甲醚仍然只是工作24/7，据杭州吉杰环保科技公司的客户服务主管周正理。

“有格兰富产品的三个主要优势，”周政立说。

第一个是在它们的测量中定量给料体积变化的精度。“通常情况下，产品在市场上只能赚1:40范围内，而格兰富产品具有很宽的测量偏差在1：800这使得格兰富适用于水厂不同的情况，”他说。

He has also been satisfied with the pumps' "highly integrated control panel, which guarantee simplified maintenance and operation." He adds that Grundfos avoided the typical leakage problem due to their products' high quality diaphragm. "That quality also guarantees that the products can apply to different conditions at the plant, like extreme humidity or temperatures," he says.

The outcome

姜压熔称该项目“在宁波的第一个现代化的自来水厂。”它坐落在该地区的一个先例。今天，浙江省利用格兰富200个多家水厂，她说。

"Grundfos pumps have served here more than 10 years without any faults or leakage problems. Thus, they earn great recognition from the plant's equity owner," she says. "These pumps ensure the water safety of 1.5 million citizens. From my side, it is an important issue with great social value."
