Application of Submersible Sewage Pump in Ore Field
Submersible sewage pumps are more and more popular in the ore field, in order to apply different environmental requirements, production processes, product performance and so on also need to have a new upgrade. In the future, what direction will mine submersible sewage pump be in?
1. Technological innovation will lead to new technology, new materials continue to mine in the use of submersible sewage pump production. For example, the traditional casting process advances to more advanced stainless steel stamping welding processes. Stainless steel stamping welding The core components of multi-stage pump with stainless steel sheet, stamping with a mold, with high reliability, good sealing, high precision, hydraulic performance and pump efficiency is generally better than the casting process of mining submersible sewage pump , Stainless steel stamping welding process is mine submersible sewage pump the future development trend.
2. Make the design to a more efficient, energy saving, environmental protection direction. For example, oil-filled motor design to more environmentally friendly water-filled motor design and development. Oil-filled submersible motor cavity filled with mechanical oil, and water-filled submersible motor cavity filled with water medium, one of its advantages is zero water pollution, more environmentally friendly. In addition, with the inverter technology in the motor design of the gradual popularization of the future mine submersible sewage pump will be more efficient and energy saving.
3. Integral design to the removable modular design direction, that is, motor and pump components such as modular combination to facilitate the demolition and replacement of damaged parts, to extend the service life of the pump, reducing the use of the cost of the purpose.
Mining submersible sewage pump in foreign countries also have a vast market, but also need some manufacturers such as Nanjing Forever Sewage Treatment Equipments Co., LTD. to actively enhance product performance and enhance the application effect, to make a full preparation to enter the overseas market.

Energy saving method of pump
Customers often ask the energy-saving effect of our products when purchase pump products.Our manufacturers will do everything we can to design energy-saving products in the production process, but customers also need to master the skills when receive products, so as to pipeline pump Product energy-saving effect to maximize. Nanjing Forever Sewage Treatment Equipments Co,.Ltd summarizes the following methods to tell you how to use pump energy-saving:
1.Try to shorten the pipeline.
2.Do not use “anti-aircraft gun” type outlet. As the water pipe to increase energy consumption, while making the pump outlet is facing the pool.
3.Try to increase the outlet pipe diameter.
4.Promptly clean up the pipeline infarcts. Foreign matter left in the inlet pipe, impeller or diversion shell flow path, will reduce the amount of water.
5.Use direct drive coupling as far as possible , which is due to the direct drive coupling belt transmission efficiency.
6.In ensuring the premise of clean water, you can remove the filter.
7.To seal the pump parts carefully check to avoid pump intake. If the pump into the air, the water will be significantly reduced.
8.Do not use the diesel engine or gasoline engine when you can use motor engine, do not use single-phase asynchronous motor when you have conditions to use three-phase asynchronous motor.

Development direction of Self-priming centrifugal pump
For self-priming centrifugal pump problems and some domestic manufacturers to focus on the development of pump protection system: automatic alarm or cut off power supply when the pump is running sewage exception occurs. While this approach can play a certain effect, but such protection is necessary, but this is not the fundamental way to solve the problem, we need to focus on improving the performance of the pump, a fundamental solution to the problem.
In addition, product development also fully take into account environmental problems, so research and development of products are more energy efficient and environmentally friendly.
In summary, the next problem of submersible sewage pump to be solved is to improve the reliability, and can adapt to a variety of work environments, optimizing the structure design, to further improve the self-priming centrifugal pump performance.

Water Pollution
The topic of water pollution continue to be raised, especially groundwater pollution problem, Hangzhou, Wenzhou and other places. farmers or entrepreneurs funded to please environmental protection bureau swim the river, in order to arouse attention to the severity of water pollution, although each environmental protection bureau have chosen silence or denial, but the awakening of public awareness of environmental protection, the degree of concern about water pollution reached unprecedented.
Surface water pollution is obvious that groundwater pollution is shocking. China’s 1.3 billion people, 70% of drinking groundwater, more than 660 cities in more than 400 cities with groundwater as a source of drinking water. But according to reports, over 90% of urban groundwater has been contaminated.
Another set of data also showed that the groundwater is facing serious challenges. In 2011, Beijing, Shanghai and other nine provinces of 857 monitoring wells within the jurisdiction been evaluated water quality class I, class II monitoring wells accounted for 2%, while Class IV, Class V monitoring wells up to 76.8% .
Nine provinces, the water quality was undoubtedly the best is Hainan Province, mainly in Class II; Shanghai, Beijing followed, mostly Class III; Heilongjiang and Jiangsu accounted for the highest places Class IV, and Jilin, Liaoning, Guangdong Ningxia four provinces generally only reach the level of V class.
Growing water pollution, so that the sewage treatment and recycling industry has been unprecedented attention the past two years, the regional gross margin remained at 70%, and even more than 100% in some areas, industry development potential is very large.
Sewage treatment requires the use of a device comprising: a sewage treatment pond, submersible sewage pump, submersible mixer, purification pools.

Submersible sewage pump can be used for a variety of jobs
Special attention to the type of ESP is required when using certain types of liquids. ESP’s commonly used on board naval vessels cannot be used to dewater contaminated flooded spaces. These use a 440-volt A/C motor that operates a small submersible pump.
It can also be used out of the water, taking suction with a 2-1/2 inch non-collapsible hose. The pumped liquid is circulated around the motor for cooling purposes. There is a possibility that the gasoline will leak into the pump causing a fire or destroying the submersible pumps, so hot water and flammable liquids should be avoided.
Submersible sewage pump can be used for a variety of jobs including draining pools and flooded basements, or even regularly maintaining water levels in water storage areas. The basic utility pump is a device that, when submerged in water, pumps water from below its casing through a connected hose to an outfall area. There are a variety of pumps on the market, but here is the basic process of using this type of utility pump, regardless of application.
