Excessively high outlet temperature of the screw air compressor
Thread Content
A 90KW single-screw air compressor frequently triggers high-temperature alarms during operation. It's the height of summer, with air temperatures around 35-40 degrees. The exhaust temperature can easily rise to around 100 degrees. What are some of the possible factors, roughly speaking?
1: Determine whether the cooler has too much dust, which leads to poor heat dissipation and high temperatures. 2: Check the oil level; if it is too low, insufficient lubrication of the engine head will lead to high temperatures. 3: Over time, the lubricating oil in the oil filter can deteriorate, and it may also contain a lot of dust and impurities. It is best to replace the oil and the filter at the same time to ensure thorough cleaning. 4: Check whether the temperature control valve is blocked. This is relatively simple – touch the two oil pipes that lead from the temperature control valve to the radiator. There is one pipe for the oil that needs to be cooled, and another for the already-cooled oil that returns to the oil reservoir. If both pipes are very hot and you can’t hold your hand on them for more than a few seconds, then the temperature control valve is dirty or its thermostat element is stuck... In such cases, disassemble it for cleaning or simply short-circuit the temperature control valve. 5: Check the current on the host. Is it caused by severe wear of the head bearings?
