How to Reduce Power Consumption of Submersible Pumps

How to Reduce Power Consumption of Submersible Pumps

The wear consumption of submersible pump is inevitable in the process of use. If we want to prolong its service life, the direct way is to reduce energy consumption. The following is a way to reduce energy consumption, I hope to help you: 1. damage to submersible pump bearings: the treatment is to check repair or replace bearings. 2. speed is too high: the processing method is to check the driver and power supply. Increase in liquid density 3. submersible pumps: the treatment is to check liquid density. 4. pump shaft bending: the treatment method is to correct the pump shaft. 5. the filling of the submersible pump is pressed too tight or dry: the treatment is to relax the packing and check the water seal pipe. 6. impeller and wear-resistant ring, impeller and shell grinding, the treatment is to check and repair. 7. axial force balance device failed: the treatment is to check the balance hole, backwater pipe is blocked. 8. coupling alignment bad or axial clearance is too small: the treatment is to check the alignment and adjust the axial clearance. We know that although many factors may increase the energy consumption of submersible pumps, if we can fully recognize these factors, from the product parts maintenance, operating environment and daily maintenance, this will be able to greatly reduce its energy consumption, and then prolong its service life.

Reasons for the decrease of operation efficiency of hot water submersible pump

Reasons for the decrease of operation efficiency of hot water submersible pump

Reasons for the decrease of operation efficiency of hot water submersible pump It is inevitable that the operating efficiency of the submersible hot water pump will decline after a long time of use. What we can do is to find out the causes of this phenomenon and avoid the occurrence of these problems in the use process, so as to prolong the service time of the pump and improve the efficiency of the product as much as possible 1. Due to the erosion of water flow, the inner wall of the channel and the impeller surface become rough and uneven, and the friction coefficient of the channel in the pump increases. In addition, the flow velocity of water in the pump is very large, and the head loss increases. The hydraulic efficiency is reduced. 2. Due to adding medicine or water quality in front of the pump, serious scaling or corrosion occurred in the pump shell. The serious scaling in the pump shell can increase the thickness of the pump shell by about 2 ram, and the scale on the inner wall of the hot water submersible pump can reduce the pump volume, reduce the pumping capacity, and rough the flow channel, and increase the head loss. Both the passenger volume efficiency and the hydraulic efficiency are reduced. 3. Due to the defects, cavitation, abrasion, corrosion and chemical erosion of the diaphragm pump caused by processing technology, cavities or cracks are produced in the flow channel of the pump, and vortices are generated when the water flows, resulting in energy loss. The hydraulic efficiency is reduced. 4. Cavitation on impeller surface. When the pressure pkpk is less than or equal to PVA, the cavitation of the pump blade will occur under the action of electrochemical corrosion. 5. Volume loss and mechanical loss. Due to the long service time of the pump, the leakage caused by mechanical wear and the increase of resistance make the volumetric efficiency and mechanical efficiency decrease. The hot water submersible pump should be observed regularly when it is running, so as to discover these faults as soon as possible and deal with them in time. Early treatment will not cause too much loss to the company.

Prospect analysis of market application of stainless steel submersible pump

Prospect analysis of market application of stainless steel submersible pump

With the continuous development of the country, the national income continues to increase. Stainless steel submersible pump is one of the most outstanding products in the industry because of its long service life, not easy to rust, clean and environmental protection. Over the years, more than ten million families, dining tables, bath and other places can be seen everywhere stainless steel figure. With the rapid increase of the market, the stainless steel submersible pump industry is facing a new technological innovation. Various enterprises are also competing to launch their own killer APPS AND CONSTANTLY UPGRADE THEIR R & D teams. At the same time, they are also going abroad to learn their technologies from advanced countries in the world, and the core production technologies related thereto, in order to improve the competitiveness of enterprises in the market. Development Status: The stainless steel submersible sewage pump included in the stainless steel submersible pump has been widely used in the market in recent years, because of its corrosion resistance, long service life, light weight, safety and hygiene by the majority of users love. And it costs about the same as an ordinary sewage pump, because the price of its brown metal has been rising for years. After the use of stainless steel materials are green materials, can achieve 100% recycling, so in recent years has become a stainless steel high-temperature corrosion resistant submersible pump leader. In particular, in recent years, countries in the food industry have put forward higher requirements. Stainless steel materials, because of safety and hygiene, have gradually come onto the historical stage. Regarding the rigid requirements, to stainless steel submersible pump as a representative of the stainless steel pump products began to shine in food products. At present, the consumption of stainless steel in China is 3.4 kg per capita, which is the highest in developing countries and even reaches that in developed countries, and is still increasing at the rate of 6.43% per year. Because of its own material heat resistance, wear resistance, corrosion resistance and other excellent new energy, has also been on the petrochemical, mining, power and other large-scale industries stage. This has brought new vigor and opportunities to the manufacture of stainless steel submersible sewage pumps, and at the same time it has also brought certain challenges. At present, the technical barriers to the manufacture of these pumps are still waiting for the professionals to adopt a more professional attitude, in a more scientific spirit. To sum up: to stainless steel submersible pumps as the representative of the pump products are leading the entire pump industry, and this drive the raw material market, new stainless steel materials continue to come out. With the continuous improvement of various patented technologies and norms, the entire industrial chain is constantly driven forward towards a higher and more orderly goal, and at the same time, we are also looking forward to the export of pump products led by stainless steel sewage pumps, playing made in China on the world stage.
