Solution to the non-circulation of cold water in the chiller

Generally, the chiller (small) produced by our okmarts.com already contains a chilled water circulating pump, and the chiller (large) does not contain a chilled water circulating pump. At this time, when assembling the chilled water system, an external chilled water circulating pump is required. , After the cold water absorbs the heat of the equipment being cooled, it flows back into the chiller for cooling and cooling. Even if the cold water is supplied back to the pipeline to form a circulating system, it is recommended that the location of the cold water pump is relatively larger regardless of whether the cold water pump is built-in or external. The water level of the cold water storage bucket (pool) should be low, so that the circulating water pump can suck in cold water well. However, in some cases, the cold water storage bucket (pool) may cause the cold water circulation pump due to the needs or restrictions of the installation environment. Higher than the water level of the water storage (pool), then the cold water system often fails to absorb water during operation, causing the chiller to have insufficient cold water flow (of course, this can be controlled from the failure of the chiller control operation panel The reason for the query in the display), the solution steps at this time are:

1. Use a hose from the cold water storage bucket (pool) back to the small replenishing pipe reserved on the large pipe on the cold water circulating pump to fill in (open its small valve), and use a wrench to unscrew the small exhaust plug of the cold water circulating pump ( If water comes out, tighten it again) until the water returns to the large pipe of the cold water storage bucket (pool), and pull out the hose to see if there are any bubbles. If there is, please continue to fill until there are no more bubbles. Close the small valve.

　　2. At this time, turn on the chiller for 1~3 minutes. If a large amount of water is returned to the pool, then OK.

　　 3. If the water return is not enough or there is no water return, repeat the above-mentioned irrigation action.
