  In the process of using the chiller, have you encountered the problem that the chilled water of the chiller does not circulate? How to solve the problem of the chilled water not circulating? We all know that under normal circumstances, small industrial chillers have been equipped with chilled water circulation pumps, such as Packaged air-cooled chillers,  box-type water-cooled chillers , and large capacity chillers such as  screw chillers  and open-type water chillers. The chiller does not contain a chilled water circulating pump. At this time, when installing the cooling water system, an external chilled water circulation pump must be installed, so that the cooling water returns to the chiller for cooling after absorbing the heat of the cooling equipment, so that the cooling water supply pipe forms a circulation system. It should be noted that no matter whether the chilled water pump is inside the built-in chiller case or outside the chiller, it is recommended that the location of t

  An important step in the commissioning of screw chillers and scroll chillers is the charging of refrigerant. Generally,   Oumal screw chillers  are filled with the specified type of refrigerant before leaving the factory. After the chiller arrives at the chiller installation site, first check whether the screw chiller is damaged during transportation, check the high and low pressure gauges, and confirm whether the chiller is in good condition. If it is found that the refrigerant is insufficient or leaking, you need to find out the leak place and fix it, and then add the specified type of refrigerant according to the product instructions. For some screw chillers, the refrigerant needs to be emptied for transportation due to transportation problems. Therefore, after the machine arrives at the installation site, the refrigerant needs to be added again, and the appropriate refrigerant must be added according to the manufacturer's requirements. Before adding refrigerant, the air in th
