Because the liquid is incompressible, the gear metering pump will have a corresponding speed according to different material characteristics, so when debugging the gear metering pump for the first time, the gear metering pump must be started at a lower speed. After the flow is stable, adjust it to the required flowTap the motor and observe if the direction of the gear metering pump is correct. If it is not correct, please switch the position of the wires. On the basis of ensuring the correct rotation of the gear metering pump, start at low speed and observe whether the pump starts to deliver liquid material within 15 seconds.1》 If you start conveying, let the gear metering pump rotate at low speed for a while and then slowly adjust it to the speed you need to start working2》 If the liquid material delivery does not start within 15 seconds, please stop immediately and remember to let the gear metering pump idle for more than 30 seconds, otherwise it may damage the gear metering pump; Recheck the above items, if still not working, please contact the manufacturer.
