Concrete Mixing Pneumatic System Of The Common Breakdown
Posted on: October 1, 2011
Gas system is Concrete mixing plant Action actuators, and its role is in accordance with the instructions issued by industrial computer switches the aggregate time positions, mixer discharge gate, cement, said discharge gate, on the Cement silo Break within the cement arch, on the Additive Blowing stirring, ensuring a variety of aggregate, cement, additives, accurate measurement, and complete the task finished loading materials. Use only the correct maintenance of the system to ensure efficient production machine and a good economy.
Its common mainly in the following five kinds of failures:
1. Gas supply failure Common air supply failure occurred in the compressor, valve, piping, compressed air treatment components.
(1) air compressor non-return valve common failure is the damage, piston ring wear serious damage and the air intake valve films Filter Plug.
The compressor stops automatically after ten seconds, the power switch off, moving their hands a large tape drive wheel can more easily if rotated, then that check valve is not damaged, or corrupted; also can Automatic pressure switch below the exhaust vent to judge the situation, if the compressor has automatically shut down after the exhaust until the compressor start again when stopped, then shows check valve has been damaged and need replacement. When the compressor pressure rise in the oil slowly and accompanied by channeling phenomenon that has serious air compressor piston ring wear, should be replaced. When the intake valve become damaged or clogged air filters, air compressor pressure will also rise slowly (but not the phenomenon of channeling oil). The palm of your hand up to the air intake filter, if there is heat out the top, then shows the intake valve is damaged and needs replacement; if the suction of small, usually caused by dirty air filter, clean or replace the filter should be device.
(2) valve trouble. Stress transfer is not high, often broken or diaphragm pressure regulator spring break, must be updated; pressure increased slowly, usually blocking filter should be removed clean.
(3) pipeline failure. Leaks and hose fittings broken by the sound of it the site of leak, if the accumulation of condensation water pipe easy to freeze and plug the gas line, should be immediately removed.
(4) failure of compressed air treatment components. Oil-water separator Filter Blocked, broken sewage is not Valve's moving parts and flexible. Filter should be regularly cleaned to remove the oil discharge valve and other impurities. Does not drip oil mist, oil cup the bottom of the deposition of water, oil cup Ring Damage, etc.. Should check the air flow inlet is lower than the fog flow, air leaks, fuel adjustment needle is sharp and so blocked.
2. Cylinder Fault (1) cylinder, the external leakage, usually installed because of eccentric rod, oil shortages, seals and sealing ring wear or damage, the cylinder rod with impurities and other injuries caused. Should re-adjust the center of the piston rod, take regular checks of oil mist on the Reliability and timely removal of impurities within the cylinder; piston rod injuries, should renewal cases.
(2) the output power cylinder and the movement is not smooth enough, usually because of the piston or piston rod is stuck, poor lubrication, insufficient supply, or the cylinder with condensed water and impurities. The center of the piston rod should be adjusted; check the reliability of the lubricator; gas pipeline is blocked, the cylinder should be promptly removed condensate and impurities.
(3) Cylinder cushion adverse effects, usually due to a buffer ring worn or damaged adjustment screw, replace the seals and adjustment screws.
(4) piston and cylinder head damage, usually due to installation of eccentric rod or buffering does not work, should adjust the center of the piston rod, if necessary, replace or adjust the screw ring buffer.
3. Valve failure
(1) can not change to or for the slow. Lubricator should first check whether the work of normal; lubricating oil viscosity is appropriate. When necessary, replace the oil, clean the sliding valve springs and valve parts or replacement.
