Chiller that has been running for a long time, how to not maintain it regularly, it is inevitable that there will be some small problems, as an industry practitioner, you must pay attention to it, now we Dannice share with you some problems about the pump to help solve it faster, which is conducive to the production and operation of the product.

Dannice summarized the following pump fault phenomena: abnormal pump noise, overloaded pump, violent vibration, unable to absorb water, unable to start, insufficient flow, pump heating, etc.

First of all, let's talk about the fault of abnormal noise of the water pump:

1. There is air in the pump. When air enters the pump, the efficiency of the pump decreases and it makes abnormal noise. Common causes include loose pipe screws, aging parts, porosity, failure of sealing valves, and so on. The solution is to replace the water pump, or inspect and repair the key damaged parts of the pump.

2. The quality of the cooling water is poor. 80% of the pump problems belong to the poor water quality causing the pump pipeline to be blocked, and the circulating water needs to be treated to meet the requirements of the chiller. In addition, it may be that the liquid level of the pool decreases or the water temperature becomes high, and we can vent it in time, or close the outlet valve a little smaller.

3. The pump bearing works abnormally. Exterior objects may be entered in the pump, we can solve it with proper maintenance.

Second,the pump overload light is on. It is generally caused by the following reasons:

1. The voltage works abnormally. We should check the power supply and determine the three-phase balance.

2. The impeller of the water pump is blocked. Clean the water pump, if necessary, replace the whole thing.

3. The pump motor is abnormal. Check the bearing and coil, if there is a need to replace the entire pump. After maintenance, it is necessary to press the reset system before the chiller can be operated again.

The severe vibration of the water pump is usually due to unbalanced electric rotor, bearing wear, poor bracket fixation, and can be dealt with by adjustment, reinforcement, straightening and other methods.

There are many reasons why the pump cannot be started. First of all, you should check whether the power supply is normal, so as to check the wire connector, switch contact, fuse, etc.

Then check the mechanical faults of the pump itself, such as fixed brackets, pump shafts, bearings, pump bodies for debris, etc. and appropriate treatment.

The above is Dannice's summary of some pump failure causes and corresponding treatment. In addition, the water pump problem should be handed over to a professional for maintenance and inspection.
