Looking for a summary of the work of the water company and a feasible plan for energy saving and con

The high-efficiency and energy-saving water pump of the water company's energy-saving and consumption-reducing summary.

After the beginning of the 12th Five-Year Plan, the completion of energy conservation and emission reduction is not ideal. In some industries, the pace of energy conservation and emission reduction is very slow, such as the water supply industry. At present, the energy saving work of the water supply company is not obvious in terms of the speed of promotion or the results achieved, and the common measures such as transformer energy saving, high-voltage motor energy saving, reactive power compensation energy saving, water pump modification or speed regulation energy saving and water supply economic operation energy saving have not received substantial energy-saving effects.

However, there are still some water companies that have broken through the limitations of energy conservation in the industry and made major breakthroughs through the replacement of pumps.

According to the author's understanding, Tangshan water supply selection Yiyang maglev submersible electric pump for equipment transformation, under the same working conditions compared with the original imported well-known brand pump, the unit consumption of water supply is reduced to, the energy-saving effect reaches 27%, a pump can save 10,000 kWh of electricity per year, and the annual electricity cost is more than 10,000 yuan. After the overall transformation, the annual electricity cost can be saved by nearly 3 million yuan, and the company has eliminated the imported submersible electric pump. Compared with the original traditional equipment, the working current is reduced from 70A to 55A under the same working conditions, and the flow rate is increased from the original 70m3 h to 75m3 The pump can save more than 10,000 kW*h per year.

Compared with the original traditional equipment, the current is reduced from 79A to 52A under the same working conditions, the unit consumption of water supply is reduced to, and the annual power saving of a single pump is about 30,000 kWh.

The reason why the above water companies can make breakthroughs is because these enterprises have found the right entry point for energy saving, realized the limitations of traditional submersible electric pumps, and have the courage to innovate, through the use of high-efficiency and energy-saving water pumps, give full play to the maximum efficiency of equipment, achieve maximum energy saving and consumption reduction, and promote the "low-carbon" sustainable development of enterprises.

Water is an indispensable part of people's lives, and water companies play an important role in people's lives. For a water company, the main power-consuming equipment is pumps, motors, transformers, etc., and the expenditure of electricity accounts for about 40% of the total cost, so saving electricity and reducing consumption is the top priority in their energy-saving work. In the state of maintaining normal operation, how to achieve power saving and consumption reduction?

1. Improve the operation efficiency of the pump and reduce energy consumption.

In the daily use of water pumps, the backwardness of adjusting Fangye socks Chang style makes the pressure of the water supply system fluctuate greatly, resulting in large power consumption and waste of electric energy. According to the current situation of the water supply system, Zhongke Yujie adjusts the utilization of equipment in real time to save energy and reduce consumption. The principle adopted is mainly controlled by microcomputer intelligence, built-in special PID regulator, when the operating frequency of the pump rises to 50Hz, the pressure is still lower than the set value, at this time the system automatically switches the pump to the mains operation, until the pressure reaches the set value, when the water consumption is small, the system controls the pump to track the pressure and automatically reduce the speed of operation, when the operating frequency is low to the set point, automatically stop the pump operation, and convert the other into power-saving operation, the water pressure can always be maintained at the set value, so that the purpose of constant water pressure is achieved.

Its intelligent power-saving system has the advantages of multiple functions, low noise, easy operation and use, and power saving.

The pump power-saving system of Zhongke Yujie is suitable for the energy-saving transformation of each circulating water pump, Songpao feed pump, condensate pump, cooling water pump, sewage pump and other pumps of the water system.

Second, the transformation and distribution of energy saving.

1) Transformer energy saving.

Transformer energy saving refers to the continuous production of transformers with lower consumption with the improvement of transformer design technology and manufacturing process, and the effect of energy saving is achieved through equipment renewal, which is embodied in the reduction of transformer air loss and load loss, that is, the improvement of efficiency. In order to reduce the loss of the transformer itself.

2) Energy saving of high-voltage motors.

High-voltage motor is the main power consumer, high-voltage and high-power are more prominent, in the field of power saving, the main popular Zhongke Yujie high-voltage motor power-saving system, mainly based on high-voltage frequency conversion speed regulation, supporting advanced, accurate modern control system, can make the high-voltage motor run in the optimal economic equivalent, reduce energy loss, improve motor efficiency.

In short, saving energy and reducing consumption is a long-term task. The energy-saving potential of water pumps and high-voltage motors is huge, and the energy-saving effect is also very good, and the investment is fast. The use of power-saving system technology and energy-saving methods can not only save energy and reduce the cost of electricity bills, but also play a role in protecting electrical equipment.
