Analysis of Reasons for Reduction of Exhaust Volume of Fusheng Piston Air Compressor
During the production process, the Fusheng piston air compressor has a problem of reduced exhaust gas volume, which makes the pressure roller of the machine unable to rise and fall, and is accompanied by a certain knocking sound. We first inspect the air muffler and clean it, then observe the oil level, find that the oil level is lower than 1/3 oil level, immediately add the same grade of oil, then start the power switch, try to open, still have Knocking. Later, the crankshaft, connecting rod, piston, and cylinder of the moving mechanism components were dismantled and inspected. It was found that the crankshaft had cracks, and it was seen that it was broken quickly. It must have been short of oil for some time. Due to lack of oil, dry friction occurs in moving parts, and each part is damaged to varying degrees due to overload operation. We cleaned and grinded the moving parts of the damage, severely replaced them, reinstalled and tested the machine, the knocking sound disappeared, and the displacement was normal. It can be seen that the oil is absolutely indispensable, otherwise it will leave a safety hazard.
The air noise filter and the air valve are not tight enough, and the reduction of the exhaust volume is also related to the tightness of the air noise filter and the air valve. The air noise filter must be cleaned up. Cleaning the dirt on the valve plate and the valve plate is beneficial to the air compressor to ensure the normal exhaust volume. The filter should be cleaned every 200 hours under normal conditions, and the gas valve should be cleaned every 500 to 800 hours.
If the quality of the lubricating oil used is not good, the piston ring will be sucked, resulting in a decrease in the amount of exhaust gas. Therefore, you should choose a high quality lubricant. After the air compressor is working for a long time, the lubricating oil contains various impurities, dust, etc., so it needs to be filtered. In general, the oil is changed every 500 to 800 hours, and the oil used in the previous time is filtered.
The high exhaust temperature of the Fusheng air compressor will also cause the piston ring to be sucked, which will easily lead to a decrease in the exhaust volume. The solution is to lower the temperature. It should be noted here that the working temperature of the air compressor should not be too high, preferably 40 degrees Celsius. If the gas valve leaks, the discharged high temperature gas will return to the cylinder. At this time, the valve should be carefully inspected, the valve plate should be polished or the valve plate should be replaced to eliminate the air leakage phenomenon of the air compressor, so that it is possible to solve the problem of high temperature of the air compressor.
