1、 Preparation before operation
1. Perform inspection
Before using pure water equipment, operators need to inspect the equipment to ensure that the parts are complete, clean, undamaged, the connections are tight, the wires and cables are intact, the valves open or close normally, and the water quality measuring instruments are accurate and reliable. For devices that are found to be abnormal, they need to be repaired or replaced in a timely manner and cannot be handled by themselves.
2. Dismantling device
When disassembling and replacing equipment components, operators need to first close the water supply valve and release the pressure in the system before disassembly to avoid posing a threat to equipment operators due to excessive pressure. After replacement, inspection and trial operation are required to ensure that the equipment is normal.
3. Testing water quality
When using pure water equipment as a reaction medium, water quality testing is required. Water that does not meet the usage requirements cannot be used and must be discharged. It is necessary to closely monitor the color changes of filter media and resin in the equipment and replace them according to the degree of change.
2、 Operation
1. Open the water source
Before using the pure water equipment, it is necessary to check whether the inlet pipeline is unobstructed and gradually open the water supply valve to avoid damage caused by sudden pressure on the equipment.
2. Operation and maintenance
During use, it is necessary to keep the equipment dry, avoid contact between incoming water components and mechanical equipment, and reduce equipment damage and maintenance frequency. If equipment failure occurs, it is necessary to promptly report for repair and shut down for processing.
3. Safe operation
The power supply of pure water equipment needs to be grounded to maintain stability, and operators need to follow operating procedures to ensure equipment safety. At the same time, attention should be paid to factors such as valve closure, power shutdown, and furniture arrangement to ensure the cleanliness and safety of the experimental area.
3、 Shutdown and maintenance
1. Shutdown
During use, it is necessary to pay attention to the cleaning time and replacement cycle of the filter element, sensor, and equipment. When the equipment reaches the predetermined running time or the filter element and cleaning reach the welding time limit, it is necessary to stop the machine for maintenance in a timely manner. When shutting down for maintenance, it is necessary to shield the water inlet to avoid contamination by sewage. It is strictly prohibited to use highly corrosive chemicals during maintenance. After maintenance, a trial run is required to ensure the safe operation of the equipment.
2. Maintenance
In order to extend the service life, regular maintenance and cleaning of pure water equipment should be carried out according to the operating procedures during cleaning. Meanwhile, in order to prevent dust from entering the interior of the equipment, daily cleaning and maintenance are necessary.
