REASON FOR HYDRAULIC CYLINDER OPERATING ON MORE LOADS

Today I am here with new fault analysis of hydraulic system and solution of this. Before some days we face a problem of sudden tripping of hydraulic power pack motor while returning in operation.wed check the whole system and find out the reason behind it.

As in general operation hydraulic cylinder taking more load when push the material forward because at that time work of pushing the material done by hydraulic cylinder but during the returning from operation there is no load on cylinder and it should come to its original position without any problem, but in our case during the pushing of material, hydraulic cylinder taking less load as compare to returning and some time tripping also.  Our team start to find out the reason behind it.

I explain here step by step action taken by us during the fault finding and solution of it.

  1. We checked that our pusher mounted on rod eye of hydraulic cylinder was free or struck anywhere in guided channel path. But after checking we found that pusher was free to move in guided channel and came easily to its natural position.
  2. After then we checked that hoses of hydraulic cylinder was not leaked from anywhere but found that hoses were in good condition.
  3. Third we checked that the solenoid operated direction control valve is working properly or not and we cleaned that valve with petrol and refitted it but problem was now still existing.
  4. After then we have checked return line filter and found the filter is chocked so it was difficult for hydraulic oil to return in tank during the return command of solenoid operated direction valve. So it take more load and some time tripping of the  electric motor mounted to run the hydraulic pump on hydraulic power pack .we cleaned the filter with petrol and compressed air and reinstall it and now we found that during returning  hydraulic cylinder take normal current .

During the fault analysis of hydraulic system we must have patient and think by open mind to find out problem and there solution.
