The following points should be paid attention to before starting the side filter sand tank: 1. Check before starting the machine. Before starting the machine, the multi-way valve of the filter sand tank should be adjusted to the filtering state. Check whether the corresponding various valves on the pipeline are in the correct state. Check whether the hair collector is blocked, if so, it must be cleaned first; check whether there is air in it, if there is, the air must be drained first.
Check whether the tank cover is tight and air-tight. If there is air leakage, the tank cover must be tightened to make it air-tight. Check whether the medicine solution pipe of each dosing system is normal and unblocked, whether there is still medicine in the medicine barrel, and whether the valve on the mouth of the dosing device has been opened to ensure that the dosing system is in a ready state. Check whether there is air accumulated in the main return pipe, and if so, it must be removed through the drain valve.
2. Start-up sequence First turn on one water pump motor; after the water pump motor runs normally, turn on the water pumps in turn, and the standby pump does not need to be turned on. After the sand filter tank is turned on, you should also check: record the pressure gauge index on the filter, check whether backwashing is necessary; check the operation of the water pump, whether it is running smoothly and without noise; check whether the dosing systems are operating normally; Check whether the water outlet of each water injection port is normal.
