    Instrumentation industry ushered in new development opportunities
    As an important part of my country's manufacturing industry, the instrument and meter manufacturing industry has played an important role in promoting the country's economic growth and social development. With the continuous development of social economy and technology, my country's instrumentation industry has been advancing all the way in recent years. How much do you know about instrumentation! Instruments and meters are appliances or equipment used to detect, measure, observe, and calculate various physical quantities, material components, and physical parameters. Vacuum leak detectors, pressure gauges, length gauges, microscopes, multipliers, etc. are all instruments and meters. In detail, instruments and meters have functions such as automatic control, alarm, sig

    Michelson innovated and upgraded the actuator to make each pipeline run more safely
    The automatic adjustment system of the industrial production process is generally composed of a detector, a regulating valve, an actuator and an adjustment object, and the actuator is an indispensable and important part of it. As the terminal product in the industrial process control system, it plays an irreplaceable role for other products in the automatic control system. From the perspective of the industry, the development speed of the implementation of electric control valves in my country lags behind other control instruments. However, this phenomenon is being changed. Not long ago, China Machinery Industry Federation and China General Machinery Industry Association held a product appraisal of "Hydraulic Actuator for Tank Root Valve and Electro-hydraulic Actu

    Selection principle of valves in petroleum and chemical industry
    In the face of so many valve classification and so complex conditions, to choose the most suitable valve for pipeline system installation, we should first understand the characteristics of the valve; Secondly, we should master the steps and basis of valve selection; Furthermore, we should follow the principle of selecting valves for petroleum and chemical industry. The principle of selecting valves in petroleum and chemical industry: the flow passage is straight through valve, which has small flow resistance, and usually is used as cut-off and open medium valve; The valve which is easy to adjust the flow is used to control the flow; Plug valve and ball valve are suitable for reversing and diverting; The valve with wiping function is suitable for medium with suspended particles.

    Precision Rotary Pump Helps Pharmaceutical Industry To Go Green
    The green development of industry needs innovation. Without innovation, the industry will not progress, and the goal of enterprise development will be difficult to achieve. Green development is not only the need of ecological civilization construction, but also the need of China's development in the new era. The high-quality development of social economy and the improvement of the quality of people's living environment must depend on the industrial progress. If the industrial production mode is relatively backward, such as the problem of dripping and running in the production process, it will produce relatively serious pollution problems, and the development goals of clean production and green industry can not be achieved. In the pharmaceutical industry, if the performance of the

    Function of Manhole on Tank Wall and Relevant Connection Dimensions
    Because the tank wall manhole is located in the lower part of the oil tank, the manhole bears a lot of liquid pressure. In order to prevent leakage, the installation quality of the manhole must be strictly required. The flanges and cover plates are processed with sealing water lines, and care should be taken to protect them during construction to avoid oil leakage during use. Make a mark every time the manhole is removed, so as to avoid dislocation during reinstallation and affect the tightness. When installing the nuts on the manhole cover, apply force evenly in pairs to prevent oil leakage caused by deformation of the cover or uneven force. The tank wall manhole is installed in the lower part of the storage tank, and is mainly used for the staff to enter and exit the storage tan
