What should I do if the constant pressure variable frequency water supply equipment of Kenfulai Water Pump Factory fails?

When the constant pressure variable frequency water supply equipment is running, system failures occur. I believe many friends are a little helpless when facing these problems. Therefore, when the equipment fails during operation, in addition to taking regular inspection measures to reduce the incidence of failures, we can also quickly find the problem when the failure occurs so that the failure can be completely resolved. Foshan Kenfulai Water Pump Factory will tell you what to do when the constant pressure variable frequency water supply equipment fails? . During the daily maintenance of the frequency converter, observations should be made during operation. There is no need to stop the machine for inspection, but the power supply must be cut off before maintenance before proceeding to the next step. However, if you want to remove the cover of the frequency converter, you must wait for a certain period of time. time to wait for the capacitor to discharge below the safe voltage to ensure safety.
The inverter must be reliably grounded to ensure safety.
Since there is a charging capacitor in the main circuit, it should be confirmed that the voltage at both ends of the capacitor is lower than the safe voltage before maintenance and inspection.
. The (or) key on the control panel of the inverter can only be used for shutdown operations, but cannot cut off the power supply of the equipment. Even if it is stopped, the power supply will continue.
Kenfulai Water Pump Factory recommends that users if there is an abnormal problem with the inverter or motor, they should stop running immediately and find out the cause according to the fault indication on the display. After the inverter stops output, if the main circuit power supply, terminals, and auxiliary control power supply are not disconnected, electric shock will occur when the output terminals, , and auxiliary control power supply of the inverter are touched. In addition, even if the main power supply is cut off, due to the charging voltage on the filter capacitor, it will take a certain amount of time to complete the discharge. After the main power supply is cut off, use a voltmeter to test the voltage of the intermediate DC circuit to confirm that it is lower than the safe voltage value before inspecting the internal circuit of the inverter. Make repairs.
