The significance of maintenance before starting the water chiller
The performance and service life of lithium bromide absorption refrigeration units are not only closely related to the startup, commissioning, and daily operation management of the units, but also closely related to the maintenance and repair of the units. As the saying goes, "The quality of a device is divided into three parts, and the maintenance is divided into seven parts." It can be seen that timely maintenance plays a very important role in the efficient operation of the unit.
Although there are many operating components and linkage equipment for refrigeration units, as long as preventive management is carried out in a planned manner, such as startup maintenance, daily maintenance, shutdown maintenance, etc., the unit can be kept in good operating condition.
Steps and Significance of Preventive Management (Maintenance) for Aircrew

01 Unit control part
Check and confirm the unit control system to improve the reliability of unit operation;



02 Unit vacuum part
Check the air tightness of the vacuum system to ensure the operation effect of the unit;


03 Safety protection device
Verification and maintenance of the action sensitivity of safety accessory devices (flow switches, pressure switches, temperature sensors, etc.) to ensure the safe operation of the equipment;
04 Mechanical part
Check the medium transmission devices at various parts of the unit, including whether the transmission components, current, voltage, and ground insulation of the shield pump are normal;


05 Heat source part
Check the pressure, temperature, and flow of the heat source to ensure the stability and safety of the unit;
06 Water system aspect
Confirm the water quality and quantity of the external water system, ensure the reliable operation of the external circulation system, and ensure the efficient and stable operation of the unit.
Maintenance before startup can greatly improve the stability of unit operation, reduce the failure rate, and increase the service life of the unit.
Professional unit maintenance should start from prevention. Only by ensuring good operating conditions and scientific operation management can the performance of lithium bromide units be maximized and brought into play!
