WFF Type String Wound Filter for Generator Stator Cooling Water System

For steam turbine generators, the stator cooling water system is significant to ensure the normal operation of the generator and extend its service life. It is necessary to purify the stator cooling water with qualified filter elements. As a professional generator spare parts supplier, Yoyik introduces you a classic type of stator cooling water filter element: the WFF type.

WFF string wound filter element is a regular used type for generator stator cooling water filtration. There are two commonly used types: WFF-125-1 and WFF-150-1. Yoyik highly recommends the two types for power plant users because of their excellent performance and low cost. It has the following advantages:

1. High filtration efficiency: The filter element is made of polypropylene fiber, which has good filtration efficiency and can effectively filter suspended solids, sediment, particles, etc. in water, protecting the generator stator from pollution and damage.

2. Long service life: being made of high-strength material, the filter element is wear-resistant, pressure resistant, and has a sturdy structure that is not easily deformed or broken.

3. Easy installation: it only needs to be installed inside the filter element housing to easily complete the replacement and maintenance of the filter element.

4. Lower cost: The price of PP cotton wound filter element is relatively low, and its service life is long. The cost of replacement and maintenance is also low, making it economical and practical.

As for the reason of the advantaged features of the WFF filter elements, it can be related to the simple and effective working principle. The WFF-125-1 and WFF-150-1 filter elements both use the network structure formed by winding polyester fibers to efficiently intercept impurities and particles in water.

Another reason is because of the processing technology of the WFF filter elements. The filter is made of PP wire winding, with simple processing technology and outstanding technical advantages. It is a very practical and economical filtering device.

Due to these advantages, WFF filter element plays an important role in the generator stator cooling water system.

1. Protection of the generator stator: The cooling water filter element of the generator stator can effectively filter out impurities and particles in the water, prevent them from entering the interior of the stator, protect the stator from pollution and damage, and extend its service life.

2. Ensure the stable operation of the generator: The internal cooling water circulation system of the generator is an important component to ensure the normal operation of the generator. If there are a large number of impurities and particles in the system, it will reduce the water flow performance, affect the cooling effect of the generator, and even cause problems such as high temperature and damage of the generator, thereby affecting the stability of the generator’s operation.

It should be noted that the filtering effect of the filter element is easily affected by the usage environment. If there are many impurities and particles in the operating environment, the filter element should be replaced faster to ensure the normal operation and service life of the generator stator.
