One trick: Choose a reasonable pump operating point to improve the operating efficiency The efficiency of the pump is an important factor affecting the efficiency of the pump station device, it is related to the design of the pump, manufacturing levels, operating conditions of the pump and the use of the situation. The operating point of the pump, that is, the actual water output, lift, shaft power and other parameters of the pump unit at a certain moment, directly reflect the working capacity of the pump unit. This is the first consideration in the design and management of the Atlantic pump industry. problem. According to the standard requirements, the operating efficiency of the pump shall not be lower than 90% of the maximum efficiency of the pump. Therefore, the operating point of the pump can only be operated efficiently within the efficient section of the characteristic curve. According to the operating characteristics and pipeline characteristics obtained by measuring the pumping technology of each pressurized station, we have adjusted most of the pumps with low operating efficiency and unreasonable operating conditions so that they can be operated at the operating point within the high efficiency section, thus improving The operating efficiency of the pump.
Second, reduce the drainage pipe resistance to improve the efficiency of the pipeline system The efficiency of the pipeline system is related to the types and quantities of pipelines, pipe diameters, pipes, pipeline accessories, and flow rates. Reducing the resistance of the drainage pipeline can shift the working condition of the drainage system to the right, reduce the resistance loss, increase the flow, and increase the system efficiency. Drainage pipe resistance loss includes the resistance loss along the drain pipe, different diameter pipe, check valve, gate valve and other parts. Loss of resistance. Among them, the drain pipe has the largest proportion of resistance loss along the way. For the existing long-term use of the drainage system, the main method for reducing the resistance along the way is to clean up the fouling of the drainage pipeline and improve the working conditions of the system. For the local resistance loss due to pipeline design problems, it is necessary to reform it as much as possible to reduce the local resistance loss and improve the efficiency of the pipeline system.
The odd move three, actively promote the application of new technologies to achieve reduction in efficiency, the use of motor frequency control technology to reduce energy consumption. AC motor frequency control technology is a new generation of power drag technology, with a high degree of automation, efficient power saving, easy adjustment; complete protection functions, simple maintenance; is conducive to extending the service life of equipment and so on. It not only has the characteristics of convenient adjustment of DC speed control system, but also has the characteristics of simple use and maintenance of AC motor. In China in the 1990s, with the breakthrough of high-power AC frequency conversion technology, the technology has been more and more widely used in civil, mechanical, electric power and other fields, and has achieved very good energy-saving effects.
Four tricks, pay attention to the rational selection of pumps to reduce energy consumption 1. A reasonable choice of pump models. At present, the efficiency of the new energy-saving water pump developed by our country can reach more than 90%, and it is safe and reliable. If the selection of pumps is improper and the pump configuration is unreasonable, a large amount of energy will be wasted, which will increase the cost of the enterprise and directly affect the economic efficiency of the enterprise. Therefore, pay attention to the rational selection of the pump, increase the transformation of the old pump, and realize the combination of the pump. From a long-term perspective, the economic effect is very considerable. Under the conditions of the planned economy, as long as the supply of water is sufficient, no one is going to calculate the economic account. Today, under the conditions of market economy, all types of enterprises attach great importance to economic benefits and are striving to maximize the benefits. As a water supply company, it is inevitably necessary to upgrade or technologically reform the equipment that consumes a large amount of energy.
2. The increase in water consumption reduces power consumption. After the technical transformation of the water pump, because the new pump has a simple structure and reliable safety, it not only meets the user's water requirement, but also facilitates maintenance and overhaul, greatly reduces the labor intensity of employees, and ensures the safety of employees and equipment. .

Hardboard is often taken from deciduous, fine - leaved trees and divided into two kinds, one is miscellaneous wood, such as beech, elm, oak, one is rosewood, such as rosewood, pear, acerbity branch, chicken wing wood, etc.In the case of oak, it is hard, stability is stronger, grain is clearer, the furniture that makes is durable, very simple and fashionable.The furniture that make is very high-grade, suit to make Europe type furniture especially.Oak is coarse, colour and lustre is elegant, wear-resisting, a lot of adornment, furniture, floor and so on material, choose to use oak to make.Practicality is more extensive, water absorption is very strong, also resist corrosion, the real wood furniture quality that makes with it is very good. Luli Group Co.,Ltd has many years of production experience and produces many high quality hardboard but low price.
