What is the life of hydraulic couplings?

According to the standard, the life of hydraulic couplings refers to the running time of the impeller or the shell damaged and can not be repaired and replaced. According to the provisions of the relevant standards, yox for belt conveyor, the life of ball mill, bucket wheel reclaimer machinery shall not be less than 20000h, hydraulic coupling for coal mine scraper conveyor life shall not be less than 10000h, coupler life shall not be less than 80000h.

Why should hydraulic couplings be overhauled regularly instead of being overhauled after all failures?

As with other machines, hydraulic couplings should be overhauled regularly, and cannot be overhauled until all are broken. If the overhaul is completed after all the damage, it is likely that the impeller, spindle, bearing and other functional components are all damaged, so that not only the overhaul difficulties, but also improve maintenance costs, extend maintenance time, increase the difficulty of maintenance. Often there is such a situation, when the coupler is abnormal, not timely maintenance, leading to impeller, spindle and other functional parts damage, eventually paralyzed the coupler can not be used, and even disassembly is also very difficult. Therefore, the coupler should provide reasonable overhaul period, regular overhaul.

How long will it take for the hydraulic coupler to be overhauled?

Germany FuYiTe company coupler overhaul period recommended for 8 years. China is not up to this level, according to the "speed type hydraulic coupling device, hydraulic coupling transmission device testing - Part 4: test technical index" (JB/T4238.4-2005) standard, the overhaul period coupler shall be not less than 16000h. The speed regulating hydraulic coupling with good condition is usually used for 3-5 years, and the limited moment hydraulic coupling standard does not stipulate the overhaul period, and should be overhauled in general 1-2 years.
