The world machine tool industry is in the first stage of the rebound. It is estimated that by 2015, the total market value of the global machine tool market will reach 530 billion yuan. The world machine tool industry is very sensitive to changes in the economic and financial environment. The economic ups and downs have affected the changes in market demand, and capacity utilization, capacity expansion and changes in business confidence have all had a major impact on the market. Therefore, the world machine tool industry faces the toughest challenges that are constantly being thrown out by the world economic recession.
“The economic recession has a profound impact on the capital product market. In addition to the weak financial environment, machine tool manufacturers are also dragged down by the processing component market, such as manufacturing, automotive and real estate.†Luo Baihui, chief researcher of Jinmo Machine Tool Network, said that As the economic recession draws to a close, the recovery of economic fundamentals will help the recovery of the machine tool industry. Due to the wide range of applications for machine tools, including aerospace, automotive, mold manufacturing, machining, wind power, mining and oil exploration, this will help the rapid recovery of the machine tool industry.
Although Europe and the Asia Pacific region still account for the majority of the global machine tool market, the recovery of the machine tool market will be mainly driven by emerging markets such as China and India. Demand for machine tools in North America is currently showing strong growth, with both production and demand growing rapidly in recent months. Luo Baihui pointed out that in the field of machine tool applications, the market for medical devices ranked third, and the total market in Europe, the Middle East and Africa is expected to reach 1.3 billion euros, accounting for 8.6% of the entire market. The annual growth rate of this field in the next five years will remain between 7% and 10%, depending on the type of medical equipment referred to. This healthy growth also reflects the market's growing demand for high-precision medical devices.
Medical device applications will drive demand for EDM machines, which are increasingly being used in the manufacture of artificial and prosthetic medical products .
The use of faster, more precise and more automated machinery in the industrial sector will become more and more popular as it will undoubtedly help improve capital efficiency and reduce labor costs.
Technological innovations are driving product manufacturers to adopt more robotic delivery methods and to replace existing obsolete mechanical solutions with products such as plc, servo and human interface. These automation products not only help to increase output, but also provide greater flexibility in operation and continuous improvement of process control.
Sprinkler irrigation and micro-irrigation automatic control equipment With the development of economy, water resources, energy shortage and labor cost increase, more and more water-saving irrigation systems will adopt automatic control. This article focuses on the advantages and classification of automated irrigation.
The advantages are as follows:
(1) It is possible to truly control the amount of irrigation, irrigation time and irrigation cycle in a timely and appropriate manner, thereby increasing crop yield and significantly improving water utilization.
(2) Saving labor and operating expenses.
(3) The work plan can be arranged conveniently and flexibly, and the management personnel do not have to go to the field at night or other inconvenient time.
(4) Since it can increase the effective working time every day, the initial capital investment in pipelines, pumping stations, etc. can be reduced accordingly.
classification:
First, fully automated irrigation system
The fully automated irrigation system does not require direct human involvement. The pre-programmed control procedures and certain parameters that reflect the water requirements of the crop can automatically open and close the pump for a long time and automatically irrigate in a certain order. The role of the person is simply to adjust the control program and overhaul the control equipment. In this system, in addition to emitters (heads, drip heads, etc.), pipes, fittings, pumps, and motors, it also includes central controllers, automatic valves, sensors (soil moisture sensors, temperature sensors, pressure sensors, water level sensors, and rain sensors). Etc.) and wires.
Second, semi-automatic irrigation system
In the semi-automated irrigation system, no sensors are installed in the field. The irrigation time, irrigation volume and irrigation period are controlled according to pre-programmed procedures, rather than feedback based on crop and soil moisture and meteorological conditions. The degree of automation of such systems is very different. For example, some pump stations implement automatic control, and some pump stations use manual control. Some central controllers are only one timer with simple programming function, and some systems have no central control. The controller, but only some of the sequential switching valves or volume valves are installed on each branch pipe.
Automated irrigation is the trend of the times. In the future water-saving irrigation projects, more and more automated irrigation systems will be applied.
