Pneumatic components for five points

Pneumatic components maintenance in the following five points: ( ) To ensure that the supply of clean compressed air compressed air usually contains impurities such as water, oil and dust. Water will make the pipe, valve and cylinder corrosion; Oil can make the rubber, plastic and seal materials metamorphism; Dust caused by body movements failure. Choose appropriate filter, can remove the impurity in the compressed air, when using the filter should be promptly eliminate accumulated liquid, otherwise when accumulated liquid near the manger, airflow can still will accrue rolled up. ( ) Ensure the air containing the right amount of lubricating oil most pneumatic actuator cylinder and control components require a moderate amount of lubrication. What will happen if poor lubrication failure under: (1) caused by friction resistance increase cylinder thrust is not enough, valve core movement failure; (2) due to the wear of sealing material cause air leakage, (3) due to rust cylinder components damage and failure of action. Lubricating oil mist detector for commonly used method of spray lubrication, oil mist, general installation after the filters and pressure reducing valve. Oil mist detector of the fuel delivery generally unfavorable and overmuch, usually every m free air for lmL oil ( The ~ drip) 。 Check whether the lubrication is a good method is: find a clean white paper on reversing valve near the vent, if the valve in the work after three to four cycles, only very light spots on white paper, suggests that the lubrication is good. ( ) Keep the pneumatic system sealing pneumatic component leakage is not only increased the consumption of energy, can also lead to gas supply pressure drop, even cause pneumatic components work properly. Serious leakage in the pneumatic system to stop running, noise caused by gas leakage is easy to find; Slight leakage with instruments, or to check by apply soap and water. ( ) To ensure that the movement parts in pneumatic components sensitivity from air compressor discharge of compressed air, contains granularity for. 。 Mu m compressor oil particles, under the high temperature of exhaust temperature of oC, these oils will quickly oxidation, oxidation after oil color darker, viscosity increases, and gradually by the liquid solidified into sludge. This mu m below the level of particles, average filter filter. When they entered after reversing valve is attached to valve heart and reduce the sensitivity of valve gradually, appear even failure. In order to remove sludge and ensure sensitivity, in the pneumatic system of pneumatic components after filter, install the oil mist separator, separate the sludge. In addition, regular cleaning valve can also ensure the sensitivity of valve. ( ) Ensure a suitable for pneumatic device work pressure and speed regulating work pressure, pressure gauges shall be reliable, accurate readings. Pressure reducing valve and throttle valve adjustment, must tighten pressure regulating valve cover or lock nut, to prevent loosening.
