Energy-saving fluid
I. Introduction
Energy is the foundation of the national economy, energy conservation is a long-term strategic approach to the sustainable development of China's economic development. In energy development and energy conservation relations can enhance the effect in the first place , this is an important way for China 's economic growth mode from extensive to intensive change. Basis and center in a position of power in China's current overall energy structure, the strategic position of power will become increasingly important. With 20 of the world since the 1980s continues to accelerate China's economic construction , power facing a huge gap. How to improve energy efficiency, reduce energy system costs , reduce environmental pollution is the most urgent task now facing .
Data show that China's power consumption is second only to the United States , ranking second in the world , energy consumption per unit output value is more than twice the world average , weak sense of energy saving caused a lot of wasted resources and property damage . United States of America , a financial magazine 's 1000 largest listed company made a survey to get the two amazing discoveries. First, the electricity bill is one of four business costs ; Second , for most businesses, the cost of electricity costs is not the last of corporate control . Transformation drain devices is an important measure to save electricity .
Second, the saving principle of fluid delivery system
Fluid delivery system run by electricity accounts for a relatively high proportion , and these are mainly electrical energy consumed by the pump system . The pump 's energy-saving measures can be summarized as follows:
①. Reduce pump speed.
②. Reduce pump torque.
③. Reduce pump running time.
④. Improve motor efficiency .
⑤. Improve the efficiency of the pump .
⑥. Work at the pump best efficiency point .
⑦. Improve water balance pipe network , change the " big flow, small temperature difference " Run .
⑧. Reduce resistance losses pipe network system .
⑨. Improve the input power factor of the circuit .
⑩. Weaken the impact of the input voltage phase imbalance .
Due to the design, installation and use , leading to a fluid delivery system is part of energy wasted . We can help you find the problem , through partial transformation of the fluid delivery system to improve the efficiency of fluid transport systems , to achieve energy-saving purposes .
Three . Saving principle of industrial fluid delivery system
Petroleum, chemical, food , HVAC and other industrial and mining production process exists fluid transport , fluid delivery system design, installation and use of the process, due to various factors , which may cause some energy waste , we can according to use case, through on-site measurements to develop a viable energy-saving programs , so pumping system characteristics and properties of the fluid delivery line coincide , as is the fluid delivery system tailored pumping equipment to help businesses reduce energy waste, improve economic efficiency .
Fluid delivery system there is a big saving space , mainly caused by the following factors:
①. Mainframe capacity wealthy
System design is based on the capacity of the host 1.1 to 1.5 times the maximum load to determine the actual load most of the time than the design load is low , when in use, if no adjustment is running according to the actual situation , it will inevitably cause a huge waste.
②. Water system capacity wealthy
System design water system , in accordance with the maximum load of the most unfavorable loop pipe network , the biggest obstacle to a certain safety factor multiplied by the selected circulating pump . This has resulted in most of the time the system is running in a large flow of water , a small temperature difference between the conditions, a lot of wasted energy.
When degeneration ③. Loads
The actual system load terminal devices that demand for cold ( heat ) quantity , alternating with the seasons , the temperature changes , the cycle of day and night , and many other factors.
Space saving summary, the fluid delivery system is great. We can help you find the problem , through partial transformation of the fluid delivery system to improve the efficiency of the system , so as to achieve energy-saving purposes .
Fourth, energy efficiency
Since 2008 until today , Ltd. Zibo thermal heating circulating pumps with frequency control technology for energy saving , proved : saving effect is obvious , significant economic benefits for two years to recover investment costs. While the system soft start, soft stop , extending the operational life of the equipment , saving maintenance costs. System debugging easy to make delivery quality greatly improved.
