The air compressor is working for a long time, which will cause the air compressor temperature to be too high, especially when the temperature is too high in summer。If the temperature of the air compressor is too high, what are the cooling skills？
2. The radiator is blocked。When there is a lot of dust around the air compressor, long-term operation causes the radiator to adhere to a layer of dust or sludge, and the internal copper pipe is also easy to be blocked by the accumulation of oil dirt, thus affecting the heat dissipation effect。
3, the oil filter is too dirty。The machine has three side-by-side oil filters, when it is too dirty because the resistance oil can not enter the compressor according to the normal flow, the compressor will heat up rapidly due to the lack of cooling oil, when the inlet and outlet oil pressure difference exceeds 0.When it is 18MPa, the filter element needs to be replaced。
4. The cooling oil level is too low。When the cooler is inspected, the oil level should be supplemented immediately when it is lower than the lower end of the inspection tube。
5, low oil label or poor oil quality。The machine uses the manufacturer's special compressor oil, with other low grade or inferior oil will make the viscosity and specific heat can not reach the standard resulting in high temperature。
6. Fan tape is broken or loose。When the tape breaks, the press will automatically stop for about 5 minutes because the temperature is too high. If the tape is too loose, it will slip, reducing the fan speed and affecting the heat dissipation. At this time, the fan tape should be replaced or adjusted immediately。
7, oil cut-off valve failure。There is an oil cut-off valve between the oil filter and the compressor，When the cut-off valve cannot be opened，Due to oil-free lubrication and cooling，The temperature rises rapidly after the compressor is started，It will automatically stop in about a minute，Remove the temperature plug at the exhaust end of the compressor host，You'll find the plug dry and oil-free，There will also be smoke from the hole，Open the manhole at the bottom of the compressor，Remove the oil cutoff valve，Flick the stem gently with your finger，See if you can push back and forth and reset easily。If the toggle or return is difficult, it is necessary to further disassemble the oil cut-off valve。If the valve stem or valve hole has oil dirt, it should be polished with fine sandpaper until it can slide easily. If the spring is broken or there is a foreign body card, it will affect the movement of the valve stem. At this time, the spring needs to be replaced or the spring and spring seat need to be cleaned。
