I. Overview As an ideal device for precision fluid metering and dosing, metering pumps are now widely used in various fields including pharmaceuticals, food and beverage and petrochemical industries. They are highly corrosive, poisonous, High viscosity and high pressure media metered addition task. After more than half a century of practical application and technical improvements, dosing pumps have now entered their rapid growth period. The proven power-driven and liquid-delivery (pump head) material technology now enables the new metering pump to deliver almost any conventional and specialty media with the same operating pressure and capacity to meet most industrial requirements. With the general increase in the requirements and automation requirements of the production process, the safety and controllability of the metering pump, as the ultimate implementing agency for the metering and adding of chemicals, have become increasingly important. The petrochemical industry is known for its high degree of automation of the production process and is one of the most widely used areas for distributed, distributed and intelligent computerized control systems, requiring a matched set of actuators - metering pumps Flexible and diverse control modes make it easy to compose various control loops with computer systems to achieve more complex and accurate process control. To comply with this new trend, internationally renowned metering pump manufacturers such as ProLogis Germany to ensure that the traditional performance of their products continue to lead the world at the same time, with the help of embedded microprocessor system, a variety of regulatory control functions and data Communication protocol integrated into the metering pump, the true from the stroke frequency to stroke length of the two-dimensional adjustment, making it the world's first product of intelligent precision metering pump. Second, the basic working principle of the metering pump As we all know, metering pump mainly driven by power, fluid delivery and regulation of three parts. The power driven device reciprocates the fluid delivery diaphragm (piston) via the mechanical linkage system: the diaphragm (piston) is sucked by the delivery fluid during the first half of the stroke and exits the pump head during the second half of the stroke; therefore, the stroke reciprocation The frequency or stroke length of each reciprocation can be adjusted to achieve the purpose of fluid delivery. Precision machining accuracy to ensure that each pump to achieve the precise measurement of the medium being delivered. Because of its power-driven and fluid delivery methods are different, metering pump can be roughly divided into two major types of plunger and diaphragm. 2.1, Plunger metering pumps are mainly ordinary valve pump and valveless pump two. Plunger metering pump because of its simple structure and high temperature and pressure and other advantages have been widely used in the field of petrochemicals. Aiming at the shortage of high-pressure medium under the condition of high pressure, the valve-less rotary plunger metering pump has been paid more and more attention. It is widely used in high viscosity medium such as syrup, chocolate and oil additives Metering added. Due to the structural disadvantage of being unable to achieve complete isolation between the metering medium and the pump lubricant, the plunger metering pump suffers from a number of limitations in high contamination prevention fluid metering applications. 2.2 Diaphragm Metering Pump As its name implies, the diaphragm metering pump uses a specially designed and processed flexible diaphragm to replace the piston, reciprocating in the drive mechanism to complete the suction - discharge process. Due to the isolation of the diaphragm, the structural isolation between the fluid being metered and the drive lubrication mechanism is truly achieved. High-tech structural design and selection of new materials have greatly increased diaphragm life, coupled with the excellent corrosion resistance of composite materials, diaphragm metering pumps have now become the main pump in fluid metering applications. In the diaphragm metering pump family members, hydraulic driven diaphragm pump due to the use of hydraulic oil evenly driven diaphragm to overcome the mechanical direct drive pump diaphragm over-concentration shortcomings, enhance the diaphragm life and maximum working pressure. In order to overcome the possible malfunction caused by diaphragm breakage in single diaphragm metering pump, some metering pumps are equipped with diaphragm breakage sensor to realize automatic interlock protection when diaphragm ruptures. The measurement of pump head with double diaphragm structure further enhances its safety For applications that are particularly sensitive to safety.
