First, the basic principle of submersible sewage pump is a used for the environmental protection industry to transport solid particles, fibers and other liquid-solid mixed liquid such as domestic sewage, industrial wastewater, mud and other pump products. WQ type submersible sewage pump consists of sewage pump, sealing system, submersible motor, control and protection system, automatic installation system and other parts. The difference with the general sewage pump is: WQ submersible sewage pump coaxial pump and motor rotation, and at the same time dive into the liquid work. Pump sealing system can effectively prevent the liquid into the motor chamber to protect the safe operation of the motor. Control and protection system to the pump in the event of water leakage, oil spill, overload, overheating, lack of equal failure, timely alarm and shutdown for repair. Second, the technical key automatic installation system Through the coupling device, so that the pump automatically install and remove the pipe system connection or disconnection. WQ submersible sewage pump is an indispensable water treatment equipment. Its safe operation directly affects the safe operation of the entire water treatment system. Therefore, the most important issue in the WQ submersible sewage pump is to ensure the reliability of the pump. The key problem that affects the reliability of the sewage pump is the pump Sealing performance and no overload performance and service life of important components, the pump seal, we used a combination of impeller hydrodynamic seal and mechanical seal of the new sealing technology, the seal reliability has been greatly improved. And in the absence of overload performance, we use the whole theory of the pump hydraulic design, while the use of dual-channel impeller, the pump not only has a larger capacity and more importantly, the pump in the entire lift range of power will not exceed the rated motor Power overloads the motor.
Alumina Ceramic Bar
The ceramic bars were subjected to single-side grinding experiments on Alumina Ceramics using diamond abrasives of different particle sizes. The ceramic rod is about 1450 ° C ~ 1600 ° C, the product shrinks sharply, especially between 1450 ° C ~ 1550 ° C, this stage needs to slowly heat up, so that the product has enough time to shrink. The fourth stage: the heat preservation stage, compared with the small size product, the ceramic rod large size product needs a longer holding time, so that the product is fully sintered. The fifth stage: in the cooling stage, due to the creep of alumina in the high temperature stage, the rapid cooling before the creep point will cause stress relaxation of the product.
