The chiller is widely used in textile factory, electronics factory, chemical factory, plastic factory, printing factory, mainly frozen water of 3-30 DEG C to cooling equipment, so as to improve the product's superior product rate, improve work efficiency. However, yesterday, customers asked East Star, they bought in other homes of water cooler evaporator pressure is too low, leading to water-cooled chillers can not work properly, seriously affecting production. Therefore, particularly hope that the East Star Refrigeration can help to analyze, in the end what is the cause of it, how to rule out?
Because each manufacturer produces cold water machine is different, East Star or suggest you consult first for your supply of water-cooled chiller manufacturers, if they can provide after-sales service is certainly the best. However, the analysis and removal of the low evaporation pressure of the water chiller will help you. East Star Refrigeration recommendations from the following 7 points to gradually check water-cooled chillers, for the inspection of abnormal, can be promptly trimmed.
1, it may be that the evaporation pressure of water-cooled chillers is too low due to insufficient refrigerant. Therefore, as long as the corresponding refrigerant can be added. But East Star Refrigeration to remind one thing: if the refrigerant is inadequate, we must check whether there is leakage. If there is an internal leak, it should be repaired, otherwise, even if the refrigerant is added, it will still be missed directly, and the problem can not be solved.
2. If the expansion valve of the water chiller is too small or the valve hole is blocked, the evaporation pressure will be too low. The utility model can be restored to normal use by blocking the big expansion valve and the drain valve hole.
3, it may be due to the blockage of the liquid supply pipeline. After checking, remove the dirt from the liquid supply line directly and solve the problem of clogging.
4. Is it caused by the oil in the evaporator? If so, drain the oil directly.
5 the evaporation pressure caused by the blockage of the drying filter is too low. Just clean and replace the dry filter.
6, if the water-cooled water cooler solenoid valve does not work, but also lead to this phenomenon. Can be repaired or replaced solenoid valve can be restored to normal use.
7, and may be caused by expansion valve "ice plug", so first check the reasons, and clear the expansion valve "ice plug" can be.
