The specific operation of various functions of the stainless steel sand cylinder

The specific operation sequence of various functions of the stainless steel sand cylinder: 1. Check the filtration function before starting: 1. Before starting the machine, the multi-way valve of the filter sand cylinder should be adjusted to the filtering state. 2. Check whether the corresponding valves on the pipeline are in the correct state. 3. 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.

4. 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. 5. 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. 6. Check whether there is air accumulated in the main return water pipeline, if there is, it must be removed through the drain valve.

7. Start-up sequence: first turn on one water pump motor, and then turn on the water pumps in turn after the water pump motor runs normally, and the standby pump does not need to be turned on. 8. Check after starting up: record the index of the pressure gauge 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 each dosing system is operating normally; Whether the water outlet is normal. 2. Check the backwashing function before starting up: 1. If the reading of the pressure gauge on the filter sand tank is higher than 2.5kg/cm2 or above, it is necessary to backwash the filter sand tank immediately.

2. Confirm that the relevant water pumps that need to backwash the sand tank have stopped running. 3. Adjust the multi-way valve on the filter sand tank to the backwashing state. 4. Confirm that the relevant valves on the pipeline are in the correct position.

5. Backwash sequence: first run the water pump; check and observe the clear water mirror on the sand tank until the water is clean; then turn off the water pump (if the backwash water cannot be checked, the duration of each backwash is preferably 2-3 minutes ). 3. Rinsing function 1. Check before starting up: confirm that the backwashing has been completed; confirm that the water pump is turned off; adjust the multi-way valve on the filter sand tank to the rinsing state; confirm that the relevant valves on the pipeline are in the correct position. 2. Rinsing sequence: first turn on the water pump; turn off the water pump after the water pump runs for 1 to 2 minutes to see the clear water mirror (the water is clear as the judgment standard).

4. Check the drainage function before starting up: 1. Adjust the multi-directional valve on the sand tank to the drainage state. 2. Confirm that the relevant valves on the pipeline are in the correct state. 3. Check whether the hair collector is blocked, if there is, it must be cleaned first; check whether there is air in it, if there is, the air must be drained.

4. Check whether the tank cover is tight and air-tight. If there is air leakage, the tank cover must be tightened to make it tight and air-tight. 5. Check whether there is air accumulated in the main return pipe, if there is, it must be discharged through the exhaust valve. 6. If there is an overflow return pipe, please close the main valve on the overflow return pipe.

(Note: During the drainage process, please try to prevent the interruption of the pump work) 5. Check the circulation function before starting up: 1. Before starting up, the multi-directional valve of the filter sand tank should be adjusted to the circulation state. 2. Confirm that the relevant valves on the pipeline are in the correct state. 3. Check whether the hair collector is blocked, if there is, it must be cleaned first; check whether there is air in it, if there is air, the air must be drained.

4. 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. 5. If there is an overflow return pipe, please close the main valve on the overflow return pipe. 6. Check whether other equipment is in good condition.

After starting up, check: whether the water pump is running normally; whether other related equipment is running normally. 6. Shutdown function Turn off the water pump, shut off all the water flowing to the sand tank or swimming pool (close the sand tank), and adjust the multi-way valve of the filter sand tank to the closed state.
