1 molding machine fault detection in air filter was blocked, because the vacuum pump working process to produce some water, long time with some foreign bodies in pipeline will be blocked in the air filter air filter, the pressure gauge at the pressure is not small, but the air flow is not enough, causing the machine to shock.
      2, due to long time vibration, will appear below the molding machine fault: connection of Taiwan and earthquake shock piston 6 M20 six nails loose, there is a gap between the platform and the shock piston, flow from leakage caused by shock, weakness, especially after shock compaction.
      3, between the piston and the pump iron does not rust, lubrication, can also cause shock to solve other machine fault, can be opened to the jolter rubber tube into a kilo of kerosene or gasoline, then a good boot shock, then shock sound will change obviously the.
