Circulating pump makeup pump control equipment operating instructions

Circulating pump makeup pump control device operation instructions The power line and the motor line are connected after the following operation. Operation flow: 1, close the circuit breaker switch. Stop the indicator light is on, the indicator light is for the next step. 2, open the pump exhaust valve so that the liquid filled the entire pump, to be closed after the exhaust valve. Check each part is normal. Press the start button of the circulating pump to see whether the pump is running. When the pump is in the manual state, it will test whether the pump is rotating normally. After normal, switch the main switch to the automatic position, and the equipment enters the automatic state. When the pipeline pressure is at the lower limit, the pump will start automatically and the upper limit will stop automatically. 3, failure and treatment: pump failure: circulating pump, make-up pump overload or lack of power or the pump blocked. Remedy: pump overload, power outage, reset the thermal relay, power transmission to see if the pump is operating normally. Use a multimeter to measure the supply voltage to see if it is missing or the voltage is unbalanced. Fuse is blown, the fuse is short-circuit phenomenon. If the pump is blocked, use a pipe wrench to turn the pump shaft. If it does not move, it indicates that there is a problem with the pump. Contact the supplier.
