High temperatures everywhere in the compressor, high pressure at all three outlets
Thread Content
For our 4M32-186 model from Shanghai Dalong Compressors, the temperature at the four outlets has risen to 143 degrees Celsius, and the pressure at the three outlets has increased. What could be the cause? Open it and check that the four-way and five-way valves are airtight, and that the five piston rings are in good condition. If the water jacket structure of the four-cylinder block has poor heat exchange efficiency, could it cause the above phenomena? This post was last edited by 1025199692 on 2009-4-4 00:54]
A 4-stage jacket with little or no water can increase the temperature at the 4th outlet, and it can also affect the pressure in the earlier stages. I’m not very familiar with the model used by the original poster, but I think the cylinder jacket of the compressor in that model wouldn’t be completely devoid of water or have such little water in it; therefore, the impact on the pressure in the 3rd stage shouldn’t be significant. Could it be that the gasket inside the valve isn’t properly installed? Of course, if there is backflow from the balance section, the poster might as well look for the cause in the backflow from that section or in the adjustments to the clearance.
Yes, an increase in the jacket temperature will cause the gas volume to expand, leading to a rise in temperature and subsequent overpressure.
Hello, could you give everyone a brief introduction to the balance section?
Generally, poor cooling at the previous stage can lead to high pressure at the next stage.
