Cause analysis of hydraulic motor oil spill

The structure of a plunger-type hydraulic motor show that, on the shaft seal has been soaking in the hot oil, and carries the leakage of oil pressure. Due to pump or motor of within relief will led to its shell body temperature above tank in the hydraulic oil of temperature, so high temperature may led to by organic material made of skeleton oil seal aging, makes its elastic reduced or lost, to led to leak oil, but through statistics found, in leak oil of hydraulic motor in the to closed type hydraulic system in the of for most, thus, caused closed type system in the hydraulic motor leak oil of reasons not high temperature led to skeleton oil seal aging and caused of.
