1. Pump maintenance and maintenance system
1) Check the oil level of the bearing lubricating oil every day, and refuel in time when there is a shortage of oil.
2) Every day, pay attention to check whether the nuts of the anchor bolts and connecting bolts are loose. If they are loose, tighten them immediately.
3) Check the shaft seal for water leakage every day, and adjust and replace it at any time.
4), disassemble and clean once a year, if any damaged parts are found, replace them immediately.
5) Depending on the situation, apply anti-rust paint on the pump body every one to two years.
2. Valve maintenance system
1), keep the valve clean and paint state.
2), apply butter on the threaded part of the shaft. Once every six months indoors and once every three months outdoors, to increase the lubrication effect caused by the friction between the screw and the nut and reduce wear.
3) For valves that are not adjusted or switched frequently, the steering wheel and steering wheel must be turned regularly to avoid rusting.
4) Valves used for chilled water pipelines and hot water pipelines to ensure that the insulation layer is not damaged, and no cold and heat loss and dew condensation water droplets will occur.
5) Valves that work automatically, such as check valves, automatic check valves, and various solenoid valves, should always check whether their work is normal and flexible. If there is any problem, they should be repaired or replaced immediately.
Also note: The valve cannot be used as a heavy object. In order not to damage the valve or affect the performance, it is strictly forbidden to stand on the valve for operation and inspection during operation and inspection.
3. Maintenance system for water pipes
1), chilled water pipe
Chilled water pipes need to be insulated, and the main task of their daily maintenance is to ensure that the insulation layer and the moisture-proof layer on the surface will not be damaged or fall off, and should be repaired in time when found.
2), cooling water pipe
Galvanized steel pipes are not coated with anti-rust paint. Cooling water is generally treated with chemicals. When it is used for a long time, it will damage the pipe wall. When it is used for a long time, it is necessary to pay attention to the corrosion problem of the pipe. .
4. Maintenance system of water filter
The water filters installed at the pump inlet, chiller inlet and fan coil inlet should be cleaned regularly. Generally, the filter should be removed and cleaned every three months. For newly commissioned cooling water systems and systems with a long service life, the cleaning cycle is shorter.
5. Protection and maintenance mechanism of expansion tank
Check several times a day to ensure that the tide level in the intercooler is moderate, the float valve is flexible, and there is no problem with overflowing. The intercooler should be cleaned several times a year, and the water tank and base should be rust-proof and painted.
