How to deal with the high-pressure overload of the chiller

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

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

The technological 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. Under the simulated process conditions, the cleaning agent is used as the cooling and heat transfer medium to complete the cleaning purpose.

      2. Various dirt cleaning technologies:

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 stains, bacterial algae, welding slag and sediment, etc., and has a fast and high-speed removal effect , 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 operation procedures.

C. Analysis and control items of cleaning process:

a. Monitoring items for cleaning process; b. Monitoring items for cleaning end point; c. Corrosion monitoring items.

D. The cleaning technology of industrial chiller condenser includes the following:

3. Analysis and control items of the cleaning process:

a. Cleaning process monitoring items; b. Cleaning end monitoring items; c. Corrosion monitoring items.

     4. Cleaning method:

a. Use the brush to clean physically; b. Use a low-temperature chiller to efficiently clean the descaler chemically.

After the condenser of the industrial refrigerator is cleaned, water treatment chemicals are added to the cooling water and chilled water systems according to the process requirements to slow down the re-scaling, and the anticorrosion film is formed on the cleaned metal surface, and water treatment will also be provided The advanced technology cleaning method:

a. Use the brush to clean physically; b. Use a low-temperature chiller to efficiently clean the descaler chemically.

After the condenser of the low-temperature chiller is cleaned, water treatment chemicals are added to the cooling water and chilled water systems according to the process requirements to slow down the re-scaling, and the anti-corrosion film is formed on the cleaned metal surface. Advanced technology for water treatment.
