Submersible sewage pump basic principles and technical key

First, the basic principle of Submersible sewage pump is a type used in the environmental protection industry for the delivery of solid particles, fibers and other liquid-solid mixed liquid such as domestic sewage, industrial waste water, 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 full-field-based theory for the pump hydraulic design, with dual-channel impeller, the pump not only has a larger capacity and more importantly, the pump in the entire lift range will not exceed the power The motor is rated for motor overload.

PVC High Speed Door

PVC High Speed Door are designed for indoor use and ensure rapid handling operations between different areas that should remain separated. These safe and efficient industrial doors are made of a shaped steel frame and covered with PVC. These high speed doors are safe and efficient and consist of a shaped steel frame covered with PVC. Safety is ensured by their photocells and barriers.

High speed doors protect us from harm, save energy and help us to separate processes for optimal productivity. A high speed door's most important job is to simply open and close quickly and safely every time you need it.

The high speed pvc roll shutter door require high strains, caused by the high operating speed and the frequency of openings, have to be taken into account during construction. In the same way, basic conditions like size and installation location add up to considerable requirements regarding safety and control technique.
