Electromagnetic diaphragm metering pump composition and quality of performance

Electromagnetic diaphragm metering pump generally consists of the control part, the drive part, the transmission part and the overcurrent part. The electromagnetic diaphragm metering pump drive part is the main part of the electromagnetic diaphragm metering pump and other metering pumps. Electromagnetic diaphragm metering pump is a metering pump driven by electromagnet and designed for conveying low pressure and low pressure pipeline liquid. It is popular in the industry due to its simple structure, low energy consumption, accurate measurement and easy adjustment The design principle of "simple and practical", but its disadvantage is that the measurement of small flow (usually 90L / h below), the pipeline pressure is relatively low, which in some ways limits its industrial applications. Electromagnetic diaphragm metering pump in quality mainly in: A, pump head: the pump head is the flow of the fluid being measured part of its quality is generally good or bad in the performance of sealing, corrosion resistance, structural stability; B, the circuit board: For circuit boards generally do not exist process design issues, but the digital circuit and analog circuits, the main quality of the performance of the seal, because the circuit board can not enter the water vapor; C, diaphragm: due to the electromagnetic diaphragm metering pump delivery They are all highly corrosive liquids and therefore have a high degree of corrosion protection requirements for diaphragms that are in direct contact with the liquid being transported.

Metal seal Butterfly Valve

Metal seal Butterfly Valve can be double offset butterfly valve and triple offset butterfly valve which Lug wafer double offset butterfly valve used to such as steaming, natual gas, shut off or regulating medium of pipeline, all type corrosive medium-non corrosive medium in chemical refinery, power generation or enviromental protection system. Metal seal butterfly valve usually suitable for high pressure system with advantages of high temperature high pressure resistance, short face to face dimension, wear resistance etc. The valve size can be from 12" to 72" with matching valve pressure from class 150 to class 2500 which operated by worm gear, handwheel, pneumatic actuator or electric actuator.
