Below are the most common malfunctions and ways to eliminate them for Carter engine heat exchangers:

Drawing problems

Leakage

Reasons: the sealing gasket is set incorrectly, left the sealing groove, damaged or aged; The plate was corrosed or deformed; The size of the clamp is uneven or absent; The clamping bolts are weakened.

Solution: adjust the position of the sealing laying, replace damaged or worn gaskets; Replace corroded and deformed plates; Tighten evenly in accordance with the indicated clamp size and tighten the weakened bolts.

Inner leak

Reason: the sealing laying is old or damaged; The plate has corrosion and has holes.

Solution: Replace old or damaged sealing gaskets; Find and replace corroded and perforated plates.

A leak between a dull plate and a clamping plate

Reason: the deaf plate was punctured with a solid object.

Solution: Replace the punctured plug.

Anomalous drop in pressure

Pressure difference is greater than the design value

Reason: the actual consumption is greater than the calculated value; The channel between the plates or the entrance to the corner hole of the plate is blocked.

Solution: check the operation of the system and adjust the flow rate within the design range; Clean the inter -plate canals and inputs of the corner holes to remove dirt, impurities and other blockages.

The pressure of pressure is less than the expected

Reason: perhaps, there is a leak in the pipeline, leading to a partial bypass of fluid; Or inside the heat exchanger, components can be damaged, which reduces the resistance of the fluid flow.

Solution: check the pipes and connections, eliminate leaks; Disassemble the heat exchanger, check the internal components and replace damaged parts.

Anomalous heat transfer temperature

The temperature at the outlet of the hot side is too high

Reasons: the heat exchanger is too small and the heat transfer area is insufficient; The consumption on the hot side is more than the design value; The plates are covered with capture and clogged; The consumption on the cold side is small.

Solution: Consider the possibility of replacing the heat exchanger with a suitable model in accordance with the actual needs; adjust the stream of hot side in accordance with the design requirements; Clean the plates of scrap and blockages; Increase the flow of cold side.

The temperature at the output of the cold side is too low

Reason: the flow of the hot side is small or the temperature below the calculated value; The plate is covered with a bewilder or locked.

Solution: increase the consumption or temperature on the hot side until the design standards compliance; Clean the plates to restore heat transfer efficiency.

Problems with vibration

Reasons: the vibration of a tube beam caused by vibration of the pump and compressor; pulsation caused by rotating equipment; exposure to a tube bunch of liquid entering with a high speed into a tube bundle.

Solution: minimize the number of launches and stops; install the adjusting groove at the inlet of the liquid; reduce the distance between the partitions; minimize the hole of the pipe beam through the partition.

Carter heat exchanger maintenance is important for maintaining their performance and extending the service life. Below are some of the main methods of maintenance:

Conduct a cleaning regularly.

External cleaning: dust, dirt, garbage and other pollution accumulate on the surface of the heat exchanger, which affects the effectiveness of heat dispersion. The outer part of the heat exchanger can be cleaned with compressed air or soft brush. For persistent stains, use a soft detergent and soft fabric, but avoid scratching the surface with hard tools. For heat exchangers installed in dusty rooms, the cleaning frequency should be increased accordingly.

Internal cleaning: depending on the type and use of the heat exchanger, internal cleaning should be regularly carried out. In the heat exchanger, deposits, such as scale and rust, which can be cleaned with chemical cleaners, can form from the water side. Before cleaning, the heat exchanger must be isolated from the system and operated in accordance with the instructions for the cleaning agent. After cleaning it, it must be thoroughly washed with clean water in order to make sure that there are no residues of the cleaning agent. For air heat exchangers, use compressed air to purge the internal channels to remove dust and garbage.

Check tightness.

Regularly check the seals of the heat exchanger: gaskets, sealing rings, etc., for their aging, damage or deformation. The compaction malfunction will lead to a leakage of the medium and violate the normal operation of the heat exchanger. If any problems with seals are detected, they should be replaced in a timely manner in order to ensure good tightness.

Check the connecting parts: including the connection between the pipeline and the heat exchanger, the flange connection, etc., to verify the reliability of the connection, the absence of weakening or leaks. For threaded connections, apply the appropriate sealant; For flange joints, make sure that the gasket is installed correctly and the moment of tightening the bolts is uniform.

Monitoring of working parameters

Temperature and pressure control: regularly register the temperature at the input and output of the heat exchanger, pressure and other parameters and compare them with normal work parameters. If abnormal changes in temperature or pressure are detected, this may indicate clogging, leakage or other malfunctions in the heat exchanger, which should be checked and eliminated in a timely manner.

Consumption monitoring: control the flow rate in the heat exchanger to make sure that the consumption is stable within normal limits. An abnormal stream can be caused by pipe clogging, valve malfunction or a poor internal stream of heat exchanger.

Maintenance of the cooling system

For heat exchangers using coolant: regularly check the level and quality of coolant. With an insufficient amount of coolant, it should be replenished in a timely manner and replace the coolant in accordance with the prescribed period in order to prevent the deterioration of its quality and corrosion of the inside of the heat exchanger.

Check the cooling fan or pump: if the heat exchanger is equipped with a cooling fan or circulation pump, make sure that they work correctly. Check if the fan blades are damaged, whether the engine works normally, whether the flow consumption and pressure meet the requirements. Timely remove the garbage around the fan to provide good ventilation.

Corrosion prevention

Take the appropriate measures to protect against corrosion: select the appropriate methods of corrosion protection depending on the material and the working environment of the heat exchanger. For example, for a metal heat exchanger, corrosion inhibitors can be added to Wednesday or treat the heat exchanger with an anti -corrosion coating.

Control the PH environment: if the fluid is the working environment of the heat exchanger, its pH should be controlled in the corresponding range to avoid corrosion of the heat exchanger due to excessively sour or excessively alkaline media.

Regular maintenance

Develop a maintenance plan: depending on the frequency of use and operating conditions of the heat exchanger, develop a detailed maintenance plan, including cleaning, inspection, replacement of the wear of parts and other types of work, and strictly follow this plan.

Professional inspection: regularly invite professional technicians to conduct complex inspections and maintain the heat exchanger, conduct a deeper elimination of malfunctions and evaluate productivity, timely detection of potential problems and take appropriate measures.
