There are several possible failures in a steam ejector vacuum system, and here are some common troubleshooting methods:
Nozzle Blockage
Check and clean the nozzle for blockages. Large particles of foreign matter can clog the nozzle and cause the vacuum to be less effective. A clogged nozzle can be judged by looking at the sound, temperature changes, or the magnitude of the vacuum pressure.
Nozzle wear:
Nozzle wear can slow down the vapor velocity, affecting the vacuum effect. When the nozzle wears more than 10% of the design value, the nozzle should be considered to be replaced.

Vacuum System Leakage
The tightness of the vacuum system is critical to maintaining the vacuum level. Leaks can be caused by gaskets not installed, misfitted or damaged, bolts not tightened, flange faces damaged, welds with trachoma, etc. Leaks can be checked by introducing pressurized air and applying soapy water to all parts of the system. For leakage problems, damaged parts should be repaired or replaced to ensure the tightness of the system.
Low operating vacuum
This can be due to a number of reasons, such as clogged nozzles, wear, or leaks in the system. The above possible causes should be investigated one by one, and repairs and replacements should be carried out accordingly.
Condenser problems
Condensers can have problems such as increased pressure and rising discharge temperatures. For increased pressure, check and repair air leakage from the lower drain, clean up the dirt blockage, adjust the sprinkler plate, remove the lower nozzle blockage, and drain excessive stagnant water. For the rise in the discharge temperature, the water supply should be adjusted to meet the needs of the condenser.
When troubleshooting, it is important to pay attention to safety and follow the relevant operating procedures. If you are not sure how to carry out the repair, it is recommended to contact a professional technician or manufacturer for maintenance. At the same time, regular maintenance and maintenance of the steam ejector vacuum system can extend its service life and reduce the occurrence of failures.
Specific steps for the maintenance of the vacuum system of the steam ejector
The maintenance of the vacuum system of the steam ejector is an important measure to ensure its stable operation and prolong its service life.
Here are some specific maintenance steps
Regular inspection and maintenance
Regularly inspect and maintain all components of the steam ejector vacuum system to ensure that all components are in normal operating condition. In particular, it is necessary to pay attention to key components such as nozzles and condensers to observe whether they are blocked, worn and other problems.
Cleaning treatment: Regularly clean the equipment internally and externally to prevent corrosion and errors. When cleaning, take care to use appropriate detergents and tools to avoid damage to the equipment.
Replace the filter element: Replace the filter element in the equipment regularly to ensure the stability of the equipment. The replacement cycle of the filter element should be determined according to the actual situation, and it is generally recommended to check and replace the equipment after a period of use.
Calibration equipment
Regularly calibrate the vacuum system of the steam ejector to ensure that all parameters meet the requirements. During the calibration process, attention should be paid to the operation specifications to avoid unnecessary damage to the equipment.
Lubrication and fastening
For the bearings and other components of the equipment, lubricating oil should be added regularly to ensure the normal operation of the bearings. At the same time, it is necessary to regularly check and tighten the bolts and other fasteners of the equipment to prevent failures caused by loosening.
Long-term storage handling
When the equipment needs to be stored for a long time, it should be handled appropriately. This includes cleaning and oiling the surfaces of the equipment, cleaning and properly placing the parts and accessories, removing the vulnerable parts for sealed storage, and regularly inspecting the storage equipment.
During the maintenance process, it is important to pay attention to safe operation and follow the instruction manual and relevant operating procedures of the equipment. If you are not sure how to carry out maintenance, it is recommended to contact a professional technician or manufacturer for guidance. Through regular maintenance, the stable operation of the steam ejector vacuum system can be ensured, the production efficiency can be improved, and the service life of the equipment can be prolonged.
