Vertical rammer oil spill happened
The problem of oil leakage of 90% above is because the rubber ring a long time due to cold and warm temperature alternation, lead sealing ring and lost a lot of plasticizer,
The problem of oil leakage of 90% above is because the rubber ring a long time due to cold and warm temperature alternation, lead sealing ring and lost a lot of plasticizer, softening agent, the hard problem of corrosion, first oil leakage, slowly dripping phenomenon, a long time sealing ring fracture
