Concrete pump suddenly sounding great fault repair method

Analysis: In the casting process, Tuobeng suddenly issued a rhythmic "giggle" sound, pressure pulse is large, carefully argued hear, determine the sounds from the hydraulic pump. If Tuobeng factory, life is not reached, according to normal use, will not damage the pump element, you can judge it may be due to pump into the air and cause this noise.

Troubleshooting: the main hydraulic concrete pump exhaust treatment for the above situation, if the problem persists, you can remove the main hydraulic pump disintegration test machine, such as found in the shoe and the plunger is "separation", you can replace main hydraulic pump, hydraulic oil and filter, and clean the hydraulic system. Try the opportunity to discover Tuobeng back to normal, the analysis can know that Tuobeng main hydraulic pump shoe and the plunger is premature failure, mainly because of serious pollution of hydraulic oil.
