The high pressure alarm of water-cooled industrial water chiller is mainly caused by the problem of cooling water, especially the cooling water tower, which must be cleaned and maintained regularly. If the water quality is poor, it is better to do water treatment first.
The chiller is a cooling water equipment that can provide constant temperature, constant flow and constant pressure. The working principle of the chiller is to inject a certain amount of water into the water tank in the chiller, cool the water through the chiller cooling system, and then send the low-temperature cooling water into the equipment to be cooled by the water pump.
High pressure alarm of water-cooled industrial chiller:
1. The water pressure in the water inlet pipe of the water cooler is too low, which causes the water flow to be too small, causing the temperature of the compressor to rise too fast;
2. Check the pressure gauge that shows the refrigerant status. If the refrigerant is insufficient, an alarm will also appear. At this time, check whether there is a leakage point. If there is any, repair it and add enough refrigerant;
3. Check whether there are impurities in the inlet water source, whether the cooling water tower is dirty and blocked, which affects the operation effect, and whether the inlet pipe of the chiller is blocked by impurities;
4. Check whether the copper tubes of the condenser have problems caused by excessive scale, poor heat dissipation and small diameter. Clean the copper tubes of the condenser regularly;
5. If the drying filter is blocked, replace it with a new filter and deal with the impurities in the water source in time.
In fact, the high pressure alarm phenomenon of water-cooled industrial water chiller is mainly caused by the problem of cooling water, especially the cooling water tower, which must be cleaned and maintained regularly. If the water quality is poor, it is better to do water treatment work first, and whether it is water-cooled water chiller, air-cooled water chiller or screw water chiller, it is all-weather work. Therefore, when it works for only 6 months, it is necessary to do maintenance work for the whole system, No later than one year.
