Oil free vacuum pump - reasons for insufficient vacuum degree of oil free vacuum pump

The reasons for the insufficient vacuum degree of the oil-free vacuum pump may include the following:

Blade wear: Insufficient friction contact surface between the vacuum pump blades and the cylinder body leads to a decrease in vacuum degree.

Wear of cylinder body: Wear of the inner wall of the cylinder body may lead to insufficient vacuum degree.

The reason for the insufficient vacuum degree of the oil-free vacuum pump is rotor displacement: the standard installation position of the rotor and the end cover is offset, which affects the vacuum degree.

Air leakage in the intake pipeline and connections: After long-term use, the sealing gasket may age or be damaged, resulting in air leakage.

Motor problem: The motor speed is abnormal, the pumping speed slows down, affecting the vacuum degree.

Oil problems: oil emulsification, carbonization, insufficient oil quantity, and incorrect oil quality may cause cylinder wear, oil pipe blockage, and oil filter blockage.

The reason for the insufficient vacuum degree of the oil-free vacuum pump is the insufficient pumping time, which leads to the residual air in the oil pump not being completely discharged, affecting the vacuum degree.

Oil seal failure: This greatly reduces the effectiveness of the vacuum pump in pumping gas and reduces the vacuum degree.

Pump body leakage: affecting vacuum degree, requiring repair and replacement of leaking components.

Poor sealing: may cause gas leakage and insufficient suction.

Oil contamination: affects the performance of the pump and requires cleaning and replacement of lubricating oil.

Water vapor content: It affects the vacuum degree and can be reduced by placing desiccants or heating the pump body.

Solving these problems usually requires inspecting various components of the pump, such as blades, cylinder body, rotor, seals, etc., and repairing or replacing them. At the same time, regular maintenance and upkeep are also key to maintaining the normal operation and high vacuum degree of the vacuum pump.
