Buying a new compressor is certainly one way to get reliable, efficient screw compressor operation – but a timely compressor overhaul can also be the key to many years of operation and energy efficiency. How?
In the compressor industry, regular and proper maintenance of screw compressors is essential for continuous and reliable system operation. One of the key aspects of proper maintenance is regular overhaul of screw compressors before permanent damage to the screw element bearings occurs. Permanent bearing damage is the final consequence of inadequate maintenance, preceded by compressor overheating, the compressor “dropping out” of operation, production stoppages caused by it, scrap, missed production targets and many other events which, by their nature, always mean unplanned costs and losses for the user.
Every manufacturer of compressor equipment specifies a service plan which, at a certain number of operating hours, includes checking the condition of the bearings, i.e. measuring vibration, and – depending on the result – overhauling the compressor. Ignoring the manufacturer’s recommendation, when every situation is taken into account and measured, always ends up costing the user.
Tehnogama is not only a pioneer in general overhauls, but also the most reliable, highest-quality provider of this service, and its clients highlight the particular quality of the overhauls Tehnogama delivers.
01What sets our overhaul apart?
First of all, we check every component inside the compressor and replace everything that is worn, so that after the overhaul the entire unit (not just the bearings that caused everything described above) is 100% sound and able to last another full service life.
02The following components are covered by a Tehnogama overhaul
Bearings and housing
The bearings and housing of the screw element are vital parts of the compressor, responsible for stable operation of the screw system. Over time they are subject to wear and damage from friction and load. Regular overhauls allow the bearings to be inspected and replaced as soon as they show signs of wear. Quality bearings ensure stable compressor operation and reduce the risk of breakdown. Once a breakdown occurs, an overhaul is no longer possible and the screw element has to be replaced with a new one.
Seals
Seals play a key role in maintaining the correct pressure and preventing gas leaks from the screw element. Over time seals can become worn or damaged, leading to gas leaks and lower compressor efficiency. Regular overhaul includes inspecting and replacing seals to ensure a hermetic seal and optimal system operation.
Screws (rotors)
The screws are the basic elements of a screw compressor, responsible for compressing the air. Damage or wear can lead to loss of efficiency and unstable operation. During the overhaul the screws are inspected in detail to determine whether they are in good condition or need replacing. This careful inspection ensures optimal compressor operation and extends its life.
Electrical systems
Besides the mechanical components, it is important to pay attention to the electrical systems of screw compressors. This includes checking electrical connectors, sensors and control systems. Regular maintenance of electrical systems ensures stable compressor operation and reduces the risk of failures caused by electrical problems.
Intake valve
The intake valve is a key part of the screw compressor that regulates gas flow in the compressor system. Regular overhaul includes inspecting the intake valve to identify any damage or blockages that could restrict flow. Maintaining the intake valve ensures smooth compressor operation and efficient airflow control.
Cooler cleaning
The cooler is a vital part of the screw compressor that cools the compressed air efficiently, lowering its temperature and increasing system efficiency. Regular cleaning of the cooler inside and out is necessary to remove deposits of dust, oil and other contaminants that can impair its function. This ensures optimal compressor cooling and extends the life of the cooler.
Minimum pressure valve
The minimum pressure valve is a key safety element of the screw compressor that regulates the minimum pressure in the system. Regular overhaul of this valve ensures it works correctly and prevents unwanted pressure variations that could damage the compressor or its components.
Flexible hoses
Flexible hoses carry fluid between different parts of the compressor. Over time they can become worn or damaged, which can lead to fluid leaks or lower system efficiency. Regular replacement of flexible hoses keeps the system hermetically sealed and the compressor running optimally.
Other mechanical assemblies
Besides the components listed, it is important to check and, where needed, overhaul all other mechanical assemblies of the screw compressor, including the motor, filters, pressure regulators and other parts of the system. Such a comprehensive overhaul ensures stable, reliable and long-lasting compressor operation.
Through all these steps, Tehnogama provides a comprehensive screw compressor overhaul service, paying careful attention to every part of the system to ensure reliable, efficient and long-lasting operation.
