Under long axis of the flushing fluid pump long axis of liquid pumps for different media, liquid pumps and cheap, there are two ways to choose from. Self-flushing: When the pumping medium is cleaning media, use this method to wash. Quoted a line from the pump outlet flange, so that the flow of fluid each bushing, lubricate the bushings, sump pump parts casting process, remove the heat generated by friction, liquid pumps, a cooling effect. External flushing: When the pumping medium is a medium containing smaller particles, the use of this method for flushing. A conduit connected from the outside, the introduction of clean wash liquid rinse each bushing, lubricating bushing, remove the heat generated by friction, a cooling effect. Also, avoid solid particles into the friction pair. FYW type non-clogging liquid sewage pump is under the introduction of foreign advanced technology, based on the combination of domestic water pump features the successful development of the new generation of pumps, energy-saving effect is remarkable, anti-winding, non-blocking, automatic installation and automatic control and so on. In the carriage of solid particles and long fibers litter, it has a unique effect. The pump uses a unique structure of the impeller and new mechanical seal, can effectively convey contain solids and long fibers. Compared with the conventional impeller impeller, the pump impeller flow channel or double channel single form, which resembles a cross section of the same size elbow, the flow of a very good coking plant for liquid pumps, together with reasonable cochlear chamber, so that the pump has high efficiency, impeller static and dynamic balance test, the pump no vibration during operation. Coking plant for liquid pumps, Chengyu pumps, liquid pumps from Hebei Cheng Yu-Pump Manufacturing Limited. Hebei Cheng Yu-Pump Manufacturing Co. (www.chengyubengye.com) (www.chengyubengye.com) located in Nanyang Industrial Zone Anguo pump.
