1. What are the types of metering pumps?
The main types of metering pumps are as follows:
Firstly, plunger and piston metering pumps are classified according to the flow section. These pumps transport fluids through the reciprocating motion of the plunger or piston, and have the characteristics of simple structure and accurate metering.
. Mechanical diaphragm metering pump: using mechanical diaphragm to isolate the working chamber of the pump from the medium, suitable for conveying corrosive or high viscosity fluids. Hydraulic diaphragm metering pump: It drives the diaphragm to reciprocate through hydraulic transmission and is suitable for high-pressure and high flow applications.Secondly, according to the driving method, motor-driven metering pumps are classified: powered by a motor to drive the pump body to work, suitable for long-term continuous operation.
. Electromagnetic driven metering pump: using electromagnetic force to drive the pump body, it has the characteristics of compact structure and convenient control, suitable for small flow and high-precision applications.Thirdly, reciprocating metering pumps are classified according to their working mode: they transport fluids through the reciprocating motion of pistons or plungers, measure accurately, and are suitable for various fluid media.
. Rotary metering pump: Conveys fluid through the rotation of the rotor, with a compact structure, suitable for low viscosity and high flow applications. Gear metering pump: Conveys fluid through the meshing of two gears, suitable for fluids with high viscosity and containing rotten particles.Fourth, classify large base metering pumps, large base metering pumps, cluster key midd
2. Performance parameters of LC300/530 pump
LC300 pump and 530 pump are two completely different types of industrial pumps with huge differences in performance parameters.
. LC300 is a large vertical long shaft pump, while 530 pump usually refers to a small flow precision metering pump.1. Core parameters of LC300 vertical long shaft pump: The "300" of LC300 pump represents an outlet diameter of 300mm, and its specific performance range is as follows: • Flow range: 60-5100 m ³/h • Head range: 13-76 m • Working temperature: The temperature of the conveying medium is unbalanced, and the hood is higher than 80 ℃ • Requirements for medium collision: ＜ 150mg/L when containing suspended solids; When dealing with wastewater containing particles, the maximum particle diameter should not exceed 2mm • Axial length should not exceed 14 meters
2. Core parameters of the 530 series metering pump (taking a common model as an example). The 530 pump usually refers to a precision metering pump, and its performance is highly dependent on the configured pipe diameter and speed: • Applicable pipe diameter: 0.63mm-2.79mm • Speed range: 0.1-55 rpm (maximum allowable speed of 170rpm) • Flow range: * When the pipe diameter is 0.63-1.65mm: 0.008-5.05 mL/min (or corresp
