Inspect the water cooler and open the valve at the base of the safety valve. 3. If it is put into use after long-term storage, drive the water supply pipeline and conduct a drainage test to check the water quality and pressure. 4. Slightly open the cooling water inlet valve, and open the exhaust valve to release air. 5. When water comes out of the exhaust valve, close it. 6. Slowly open the outlet valve of the water cooler, while fully opening the water supply valve (open the bypass by 2 turns in winter). 2017: Coal Chemical Industry – “My Technical Upgrades” http://bbs.hcbbs.com/thread-1786290-1-1.html Petrochemical Sector – “Creative Ideas for Energy Savings” event (the second phase is in full swing) http://bbs.hcbbs.com/thread-1666758-1-1.html
1. Contact the central control unit for the water-cooled chiller. 2. Inspect the water cooler and open the valve at the base of the safety valve. 3.

Slowly open the outlet valve of the water cooler, while fully opening the water supply valve (open the bypass by 2 turns in winter)
When starting up the water cooler, it is generally necessary to first open the inlet valve slightly to allow air to escape through the top drain; once water begins to flow out, the drain should be closed. Then the inlet valve should be opened fully, followed by opening the return valve, with its opening degree adjusted as needed. If the air in the water cooler is not completely removed, it will cause air resistance and result in poor heat exchange efficiency

Commissioning of the water cooler: Generally, first open the inlet valve slightly to allow air to escape through the top drain; once water begins to flow out, close the drain. Then open the inlet valve fully, and subsequently open the return valve, adjusting its opening degree as needed. If the air in the water cooler is not completely removed, it will cause air blockage and result in poor heat exchange efficiency.
