China Vane vacuum pump

Mechanical cleaning is the basic maintenance method for China Vane vacuum pump,which requires the use of cotton cloth,silk cloth or soft tools to wipe the pump body and accessories,avoiding the use of cotton yarn that is prone to fiber shedding.For stubborn dirt or slight rust,it can be lightly ground with oilstone or metallographic sandpaper to ensure a smooth and even surface.When disassembling and cleaning,it is necessary to follow the steps.For example,for rotary vane vacuum pumps,oil should be drained first,the pump cover and rotor should be disassembled,and when reassembling after cleaning,attention should be paid to applying vacuum pump oil to the friction surface to ensure lubrication.

Chemical cleaning commonly uses professional cleaning agents,solvents such as gasoline or acetone.The initial cleaning can save costs by using recycled gasoline,and subsequent cleaning requires washing gasoline or aviation gasoline.Chinese blade type vacuum pumps can be heated and soaked in caustic soda solution or cleaned with ultrasonic waves for stubborn stains on oil and air circuits.Attention should be paid to avoiding the use of water containing impurities.If cleaning with water,pure water should be used and promptly drained to prevent rusting.
The cooler and air duct of China Vane vacuum pump need to be cleaned regularly to prevent scale buildup from causing overheating or performance degradation.The cooler can be cleaned by acid washing,alkali washing or ultrasonic cleaning,and the air duct needs to be blown with compressed air to ensure the removal of particles and oil residue.After cleaning,the components need to be dried and the oil circuit should be blown dry with compressed gas to avoid residual solvents affecting operation.
Oil change is an important part of maintenance,which requires draining the old oil and flushing the China Vane vacuum pump body several times with new oil.Use specialized vacuum pump oil and prohibit mixing with oils with high saturated vapor pressure such as diesel or gasoline.The cleaned parts need to be dried and coated with vacuum pump oil for rust prevention,and the parts to be repaired should be covered to prevent dust.When changing the oil of the rotary vane pump,it needs to run briefly to make the oil thinner and facilitate the discharge of old oil.
When cleaning,protective equipment such as goggles and masks should be worn,and chemical solvents should be compatible with the pump body material to avoid corrosion.Gas phase cleaning can quickly remove dirt with nitrogen or hydrogen,but it is necessary to ensure ventilation in the operating environment.If the pump body is severely scaled or the components are aging,the China Vane vacuum pump should replace the parts in a timely manner,and the cleaning cycle should be adjusted according to the actual usage situation.
