Lanshen Group is able to produce its own pump core components – motor.
Coil motor used in sewage pump is a copper coil.
Lanshen group is submersible wastewater pumps manufacturer, submersible pumps manufacturer, sewage pumps manufacturer.
Submersible sewage pump is provided which is adapted for location in a sump or the like, and which includes a motor case, a driving motor, an impeller case, and an impeller located in the impeller case, the impeller defining a back shroud space between its upper face and the confronting, superjacent portion of the impeller case.
The usual submersible pump is sealed against fluid entry for operation in a submerged condition, and is designed to be cooled by the liquid material within which it is submerged. Dangerous overheating can occur if such a pump is not operated in a submerged condition, and such overheating may result in burning or explosion of the motor.
The apparatus includes a vent which opens at one end into the back shroud space and at the other end opens to the exterior of the impeller case. Whenever air is drawn or injected into the low pressure vortex area of the sewage pump for controlling the amount of liquid discharged, the air collecting in the back shroud space is constantly vented to facilitate operation of the impeller and reprime the pump.
With the increasing popularity and expansive application of the submersible pumps for well,submersible pumps for well have to be adapted in different environments. With the accumulation of market feedback data, the application of CAD, CFD and other computer-aided design, manufacturing and supporting the use of auxiliary test software, as well as fluorine plastic, lined with plastic, rubber lined, sprayed ceramics and other new materials and new technology, submersible pump for well is gradually developing towards high efficiency, energy saving, environmental protection direction. details as follows:
① Technological innovation will drive new technology, new materials are constantly used in the production of submersible pumps for well. For example, the traditional casting process to a more advanced stainless steel stamping welding technology development. Core components of stamping and welding stainless steel multi-stage pumps made of stainless steel sheet, with molding and high reliability, good sealing, high precision, etc., the hydraulic pump efficiency and performance generally better than the casting process to produce wells with submersible pumps, stainless steel stamping and welding processes are wells with submersible pumps future trends.
②Design is more efficient, energy-saving, environmentally friendly. For example, oil-filled motor design to more environmentally friendly water-filled motor design development. Oil-filled submersible motor cavity is filled with a medium machine oil, and water-filled submersible motor cavity filled with the medium is water, one of the advantage of zero pollution of water bodies, more environmentally friendly. In addition, with frequency conversion technology in motor design and gradually spread, wells with submersible pumps will be more efficient and energy saving in the future.
③The overall design is developing to removable modular design, namely modular combination motor and pump and other components for easy removal and replacement of damaged parts, to prolong the life of the pump, and reduce costs.
