What is the reason for the overload of the water pump of the air cooled industrial chiller?

1. Excessive load: when the installation method or piping of the water pump is incorrect, such as the water pipe of the water pump is too thin, or the customer’s load (the number of intercooled titanium pipes is too small) will increase the running resistance of the water pump, resulting in an increase in the running current, triggering the action of the protector, and indicating the overload fault of the water pump.

2. Dirty things enter the centrifugal water pump of the GX/GY -65°C ~ -10°C Industrial Refrigerators and jam the centrifugal impeller: when dirty things are sucked into the water cooling equipment resources by the centrifugal pump, the centrifugal impeller of the centrifugal pump will be stuck, which will expand the friction resistance of the centrifugal pump operation, as well as the operation current of the centrifugal pump will expand, and the protective device will be opened.

3. Problems of the water pump itself: poor bearing, insulation resistance drop of heating coil after long-term operation, etc.

4. The switching power supply of the power supply system is abnormal: when the switching voltage of the power supply system of the centrifugal water pump of the industrial water chiller is too high or too low, it is a common fault that causes the centrifugal water pump to operate with too much current and cause the load of the centrifugal water pump.

The regulating object of the chiller regulating system is a relatively basic link in the regulating cooling equipment section system.

All regulating equipment serves it, and the regulating system is designed and adjusted according to the characteristics of the regulating object.

The regulating quality of the regulating system is not only related to the dynamic characteristics of the regulator, but also to the dynamic characteristics of the regulating object.

In fact, the dynamic characteristics of the regulating object determine the regulating process and quality to a certain extent.

The regulator only corrects the qualitative indicators of the regulating process as much as possible according to the characteristics of the regulating object, and the degree of improvement is also limited by the nature of the regulating object and the nature of the regulator.

Studying the characteristics of the regulating object is the basis for designing a good regulating system.

What causes the compressor overload of industrial water chiller

There are many reasons for compressor overload of industrial water chiller. For example, we usually check these problems for compressor overload of water chiller.

1. The overload protection current of the compressor is reduced, resulting in frequent overload alarm. The overload protection current needs to be increased.

2. The high pressure of the compressor is blocked, causing the compressor overload alarm.

3. The compressor itself has problems and needs to be replaced.
