It is an instrument used to detect, display, record or control process parameters in industrial production processes, also known as an industrial instrument for detecting, displaying, recording or controlling process parameters, or (industrial) process detection and control instruments. As the earliest brand in China to independently develop communication servo systems, the industrial automation series product line includes a full range of communication servo systems, frequency converters PLC、 Touchscreens, visual products, and motion control systems, as well as intelligent unit products that integrate motion control and robotics with control systems as the core, provide customers with personalized automation solutions from single axis to single machine to unit.

For a long time, data transmission between process industry field instruments and control room control systems has been mainly based on low-speed fieldbus. With the development of automation and intelligent technology, the demand for data transmission in industrial sites is increasing. On the one hand, with the improvement of automation, the number of data transmission devices such as field instruments and actuators has doubled; On the other hand, the amount of data from a single on-site instrument and actuator is increasing. In addition to instrument measurement data and actuator instruction data, instrument body data, operational data, and other environmental data also need to be transmitted to the control system. The existing data transmission technology requires a large amount of copper core cables and installation space, but the data transmission rate is very low, which has become a bottleneck for the development of industrial automation and intelligence, and cannot meet the market and technological development needs.

In recent years, China's electrical engineering has developed rapidly, and different types of automation technologies have gradually been used in the chemical industry. Among them, the key ones used are chemical instruments and automatic control systems, which play an important role in the development of the chemical industry. Therefore, it is necessary to pay attention to the use of chemical instruments and the selection of automation control systems. Instrumentation is the ability to automatically control various components in instruments and meters with the support and guarantee of automation control technology, achieving the goal of automated control of instruments and meters. Automated instruments and meters are mainly composed of three modules, namely sensors, transmitters, and displays.

Thin oil lubrication uses mineral oil as a lubricant. Thin oil has characteristics such as fluidity, adhesion to metal surfaces, certain viscosity and heat capacity, and stable lubrication performance. It also has a certain anti-corrosion effect. However, thin oil is not easy to seal, and the lubrication surface of equipment is prone to impurities such as water and iron oxide scale.


Thin oil dispersed lubrication: There are two types of thin oil dispersed lubrication: manual lubrication and fully automatic lubrication. Manual lubrication is generally only used for small parts that are not frequently moved


Thin oil lubrication uses mineral oil as a lubricant. Thin oil has characteristics such as fluidity, adhesion to metal surfaces, certain viscosity and heat capacity, and stable lubrication performance. It also has a certain anti-corrosion effect. However, thin oil is not easy to seal, and the lubrication surface of equipment is prone to impurities such as water and iron oxide scale.


The types of rubber flexible vibration damping soft joint products should be assembled according to the assembly instructions during installation, otherwise product damage and other common problems may occur. To avoid the occurrence of the above-mentioned situation, please strictly follow the installation and use manual for the operation process. Rubber shock-absorbing soft joints have good comprehensiveness and can be used to connect valve fittings, vibrating pipelines, and pipelines with frequent changes in temperature. Rubber flexible vibration damping soft joint assembly is commonly found in the fields of sea surface, water, cold and hot water, drinking water, domestic sewage, light fuel oil, lubricating grease, wholesale of finished oil, steam, natural gas, steam and fine particulate matter powder. The series circular vibrating screen motor is connected to the exciter using a flexible coupling. The exciter can be disassembled and replaced as a whole. The bearings are lubricated with thin oil, and lubricating oil can be added once during operation, making maintenance and upkeep convenient.


Oil air lubrication is a new type of lubrication method that mixes thin oil with compressed air or nitrogen to form an oil air flow, which is transported to the friction lubrication point through pipelines in the form of fine oil droplets. The methods of continuous and intermittent gas supply can meet the continuous and stable lubrication needs of continuous casting equipment.
