In life, speaking of screw chiller, perhaps everyone is not clear what this is. But in fact, screw chiller is now on the market in a lot of machinery and equipment will be used. So, how should the specific screw chiller be maintained? Below, the central air conditioning maintenance small series to give you a good introduction.

Because the cooling water of the water-cooled condenser is an open circulation loop, the tap water is generally used for circulation through the cooling tower. When the content of calcium salt and magnesium salt in water is large, it is easy to decompose and deposit on the cooling water pipe to form scale, affecting the heat transfer. Too thick scaling will also reduce the flow section of cooling water, reduce water volume, and increase condensing pressure. Therefore, when the water quality of the cooling water used is poor, the cooling water pipe is cleaned at least once a year to remove the scale and other dirt in the pipe.

Filter dryer is an important part to ensure the normal circulation of refrigerant. Because water and refrigerant do not dissolve each other, if the system contains water, it will greatly affect the operating efficiency of the unit, so it is very important to keep the system dry, and the filter element inside the dryer filter must be replaced regularly.

The condenser and evaporator on the screw chiller belong to the pressure vessel. According to the regulations, the safety valve should be installed on the high-pressure end of the unit, that is, the condenser body. Once the unit is in an abnormal working environment, the safety valve can automatically relieve pressure to prevent the harm caused by high pressure to the human body. Therefore, the regular verification of the safety valve is very important for the safety of the whole unit.

After long-term use of the unit, the oil quality of the lubricating oil deteriorates, and the impurities and moisture inside the oil increase, so it is necessary to regularly observe and check the oil quality. Once the problem is found, it should be replaced in time, and the brand of the replaced lubricating oil must comply with the technical data.

The above is the relevant content of the maintenance of screw chiller introduced by Kunshan Central air conditioning Maintenance Editor. Although we are not so familiar with the screw chiller, if we can understand the maintenance of the screw chiller in advance, it is still better. Therefore, I hope the introduction of Suzhou central air conditioning installation project will be helpful for everyone.
