[Three rain valve to recommend star products - mechanical seals] Introduction: ①WQ submersible sewage pump, where they are potential sewage, WQ is non-clogging sewage pump sewage pump is intended to thinking, as opposed to the type QW the most common. WQ reason why is because no clogging impeller design and QW is not the same, not easy to plug WQ30-22-4 pumps, as to whether the material is stainless steel that is the problem WQ100-6-4 pumps, common carbon steel material, generally can not tolerate some of the water contained in the acid-base thing, susceptible to corrosion, corrosion resistance of stainless steel can. ②JYWQ automatic stir sewage pump with automatic stir sewage pumping again, thus ensuring that the medium density, clogging, ③WL vertical WQ submersible sewage pump is non-clogging sewage pump installed vertically, YW is a liquid under the formula submersible sewage pump, having the liquid pump characteristics WQ80-8-4 pumps, AS actually the same pump, but she generally be equipped with a hose. [Three rain valve to recommend Star Products - Mechanical seal] Description: submersible sewage pump axial force than the average horizontal pumps to be large, while the balance of difficulty harder than the vertical pump. Therefore, sewage pumps, bearings easily damage their cause and axial force has a great relationship. If the installation Vice impeller, the liquid in the direction of the sub-wheel differential force is the force of the two opposite forces, which can offset part of the axial force, also played a role in extending bearing life. But with deputy impeller sealing system also has a drawback, that is in the sub impeller part of the energy is consumed, usually around 3%, but as long as the design is reasonable, can reduce this part of the loss to a minimum. WQ80-8-4 pump sewage pump _ selected three rain (certified) _ sea water pump provided by Valve Co., Ltd. Tianjin three rain. Valve Co., Ltd. of Tianjin, rain (www.tjsymf.com) (www.tjsymf.com) is a leader in Tianjin, seals, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Three rain valve leadership with the staff warmly welcome all inquiries negotiations to create three rain valve better future.
