Send the appearance of a metering pump; I’ve never seen one before. Does anyone know what the working principle is?
A metering pump generally has a square or cylindrical housing, inside which there are usually one or more screw, gear, or plunger mechanisms, along with corresponding inlet and outlet pipes and control devices. As for the working principle of metering pumps, it may vary depending on the type. The working principle of a common metering pump is to create a pressure difference within the pump through the movement of screws or pistons, thereby enabling the measurement and delivery of flow rate. A screw pump draws liquid into the pump through the rotation of the screw, and then pushes the liquid to the outlet as the screw continues to rotate. A piston pump generates compression and propulsion of the liquid within the pump chamber through the reciprocating motion of the piston. In addition, there are some special metering pumps, such as gear pumps, which draw liquid into the pump through the rotation of gears and push the liquid to the outlet as the gears rotate. In general, a metering pump is a device used to accurately measure and deliver liquids, and its working principle is based on the movement of mechanisms such as screws, plungers, or gears. .
This is likely a remote pump head; when the temperature of the medium exceeds 160 degrees Celsius, by using this remote pump head, the temperature of the liquid medication does not reach the hydraulic part of the pump. The hydraulic part of the pump still features a PTFE diaphragm rather than a metal diaphragm, which helps to reduce the cost of the pump.
Wasn’t there a manual when it was purchased?
The high-pressure variable-frequency metering pump features a cooling motor at the top and a working motor at the bottom, allowing for precise flow control via PID, thus offering a high degree of automation.
Is the pump head located at the point where it connects to the pipeline, with the inlet and outlet of the pump being on the same pipeline?
It appears to be a diaphragm metering pump; it’s not possible to tell whether it operates at high pressure. It is explosion-proof, the motor uses standard frequency power, while the fan uses variable frequency drive.
