Cottle troubleshooting a compressor, compressor production Cottle checked before: two, Cottle lower air compressor displacement causes of failure and repair methods: Failure: Cottle air compressor displacement reduced by 1, failure reasons: lack of oil displacement is reduced and there is a direct relationship between the lack of oil. We once in production, reduced displacement compressor appeared failure, not only can not make the press roller down, and accompanied by some Knocking sound. 2. Cause: The air filter and muffler bad valve tightness Maintenance: reducing the displacement is also related to the air tightness of the filter and valve silencer. Muffler air cleaner must wash cleansing. On dirt valve plate, valve on the compressor cleaning is beneficial to ensure the normal displacement. Under routine every 200 hours on the filter should be cleaned once every 500 to 800 hours should be cleaned once a valve. 3, the failure reasons: poor quality lubricants Maintenance: poor quality lubricants can cause piston rings to be sucked, thereby reducing the displacement. Therefore, air compressor parts, should choose high-quality lubricants. After long-term work, will contain impurities, such as dust in the oil, and therefore must be filtered. In general, every 500 to 800 hours should be replaced once the oil, and the oil before the first use of filtering. 4, because air compressor malfunction: exhaust temperature ultrahigh repair method: the exhaust temperature will cause the piston rings are ultra suck, cause displacement decreases. As long as the temperature is lowered, they can solve the problem. Here we must note two things: (1) high ambient temperature should generally not exceed 40 ℃. (2) If the valve leakage, high temperature exhaust gas will return cylinder which we should be careful to check the valve, the valve plate to replace the valve grinding piece Cottle European air compressor, it was possible to solve the problem of ultrahigh temperature. Selection of common sense Cottle compressor selection of the most important considerations Cottle compressor: [Cottle] working pressure compressor representation pressure units a lot, here introduces screw air compressor popular pressure, said unit; ① working pressure, discharge pressure often called domestic users. Working pressure is the maximum pressure of the gas compressor discharge; ② common working pressure units: bar or Mpa air compressor, 1 bar = 0.1 Mpa; ③ general, users usually put pressure units called: Kg (kilograms) , 1 bar = 1 Kg. Volume flow [Cottle] ① volume flow of air compressor air compressor prices, domestic users often called displacement. Volume flow is defined as the desired discharge pressure, gas volume within the compressor discharge per unit time, converted to the amount of intake air conditions. ② volume flow units: m3 / min (cubic meters / minute) or L / min (l / min), 1m3 (cubic) = 1000L (l); ③ general, commonly used in flow units: m3 / min (cubic meters / min); ④ volumetric flow in our country is also known as displacement or plate flow. [Power] ① general Cottle compressor, air compressor power is matched by means of the drive motor or diesel engine nameplate power; ② power units: KW (kilowatts) or HP (horsepower / hp), 1KW ≈ 1.333HP. Working pressure (exhaust pressure) Selection: When the user is ready to buy air compressor, we must first determine the required gas side pressure of work, plus 1-2 bar margin, and then select the air compressor pressure , (the margin is considering installing a pressure loss from the compressor to the actual location of gas pipes at a distance, according to the length of the distance between margin pressure due consideration 1-2 bar).
