If the leakage is more, should find out the reason to try to eliminate. If still invalid, should remove check and reinstall. General hydrostatic test pressure in 2 ~ 3 kg/cm2.　　C, according to the pump rotate to turning, check whether the light evenly. Such as turning demanding or not move, should check whether assembly size error, installation is reasonable.

The representative of oil seal in the form of TC oil seal, this is a kind of rubber coated with the full spring lips oil seal, the general said oil seal often referred to as the TC skeleton oil seal.　　Common materials for the oil seal are: nitrile rubber, fluorine rubber, silicone rubber, acrylate rubber, polyurethane, ptfe, etc. Material must be considered when choosing a seal material to the compatibility of working medium, and the operating temperature range of adaptability and lip edges ability to follow when high speed rotation axis of rotation. General oil seal work its lip margin of 20 ~ 50 ℃, the temperature is higher than the working medium temperature should be pay attention to when choosing oil seal materials.
