Maintenance and replacement instructions for the transmission shaft seal kit of Atlas Copco screw air compressors If oil stains or oil leakage are observed near the transmission shaft, or if the consumption of compressor lubricating oil increases abnormally, it may be due to the aging or damage of the seal kit. Therefore, it is necessary to check and replace it in time. When replacing, it is recommended to use the original kit and operate in accordance with the equipment manual to ensure that the seal is installed in the correct direction and tightly attached. In case of necessity, special tools can be used for installation to avoid deformation or damage to the seal.

Atlas Copco WD80 Operating Instructions Regularly check the levels of engine oil, fuel, and coolant to prevent equipment damage due to insufficient oil or water. Clean or replace the air filter and oil filter to prevent dust from entering the engine or compression system. Before starting, confirm that the exhaust pressure setting is correct and matches the requirements of the downstream equipment. Before long-term storage, empty the fuel and coolant (especially in low-temperature environments) to prevent cracking or corrosion due to freezing.

Common models Different models of Atlas Copco air compressors correspond to different overhaul kit models. For example, the overhaul package for the ZT110 - 145 + IMD300 Atlas oil-free air compressor has the model 3001160217. The overhaul kits for the ZR110 - 145 and ZT110 - 145 models of air compressors have models such as 8000-hour overhaul kits.

Maintenance Reminder: Check the valve core for any jamming (disassemble for cleaning) and the springs for fatigue every 6 to 12 months. Replace the aging seals in a timely manner. If the pressure rebounds too quickly after depressurization or cannot be completely relieved, investigate whether the valve core seal has failed or if the control signal is normal.

Regularly replacing the Atlas Copco filter and separator kits is an important measure for maintaining the good performance of the air compressor, reducing energy consumption and lowering the risk of failures.

Key points for installation and maintenance of the check valve assembly of Atlas Copco oil-free compressors: During installation, it is necessary to assemble in accordance with the flow direction indicated by the valve body arrow. Reverse installation will cause abnormal system pressure. The oil-free system has high requirements for cleanliness. Before installation, the interfaces must be cleaned to avoid impurities from entering. When replacing the sealing parts, only original oil-free specific accessories from the manufacturer should be used. Ordinary lubricating oil is prohibited (it will contaminate the compressed air). Regular inspection (suggested every 2000 operating hours): If there are abnormal sounds during opening/closing, leakage, or excessive pressure loss, the valve core wear or spring elasticity should be checked and disassembled for inspection.
