How to deal with the high pressure overload of the chiller

When the condenser heat dissipation is poor, the compressor efficiency is low and the operating current increases. When the high pressure rises to 19Kg/cm2, the compressor trips under the protection of the high pressure switch and the compressor stops running. Poor heat dissipation indicates that the high pressure is too high. At this time, please check whether the circulating water or cooling fan of the cooling tower is normal, and whether the cooling water temperature is too high. After the above is normal, press the reset switch (REST) to operate normally. If high pressure overload occurs frequently, you should Clean the condenser as soon as possible.

   1. The cleaning technology of the condenser of the low-temperature chiller includes the following:

   1. Process arrangement of the condenser system of the low temperature chiller:

  The cleaning system is specially designed according to the characteristics of the low-temperature chiller. Through this system, the cleaning agent can be directly injected into the low-temperature chiller water system, and the cleaning agent is used as the cold and heat transfer medium under the simulated process conditions to complete the cleaning purpose.

   2. Various types of dirt cleaning technology:

A. Requirements for the preparation of various cleaning agents and passivation and pre-filming agents: The use of excellent compatibility can effectively clean scale, rust, copper rust, oil, bacteria and algae, welding slag and silt, etc., with rapid and high-speed removal , And does not damage equipment and pipelines, safe and reliable.

   B. Cleaning technology operation process requirements: a. Control of cleaning temperature conditions; b. Control of cleaning concentration conditions; c. Scientific cleaning operating procedures.

  C. Analysis and control items of cleaning process:

  A. Monitoring items of the cleaning process; b. Monitoring items of the cleaning end; c. Corrosion monitoring items.

  D, low-temperature chiller condenser cleaning technology includes the following:

  3. Analysis and control items of the cleaning process:

  A. Cleaning process monitoring project; b. Cleaning end point monitoring project; c. Corrosion monitoring project.

  4. Cleaning method:

  A. Use a brush for physical cleaning; b. Use a low-temperature chiller for high-efficiency descaling chemical cleaning.

After the condenser of the low-temperature chiller is cleaned, water treatment agents are added to the cooling water and chilled water systems according to the process requirements to slow down the re-scaling, and form an anti-corrosion film on the cleaned metal surface, and also provide water treatment Advanced technology cleaning methods:
