When rotary vane vacuum pump vacuum pump oil change _

rotary vane vacuum pump small appearance compact structure, easy mobility. Rotary vane vacuum pump replacement water pump often happen in the operation time of the problem, many people don't know the right time, small make up a detailed answer to you today.

in the process of using vacuum pump oil, due to oxidation, emulsification and mixed causes various impurities, etc. , wherein the oil deterioration of metamorphism, and as described in the composition of metamorphic impurities to a certain extent, the color of the oil change, as described in viscosity and acid value increases, the precipitation of insoluble resin material, thus in the oil pump, steam pressure increases. At this point can't continue to use the vacuum pump oil, the pump must be replaced with new oil.

in order to prevent dust in the oil pump, oil pump in granular material is pulled together into the pump chamber. For some of the process. In the process of the operation of the pump, should be provided with continuous filtration unit. Dust and impurities pollution oil sink after their box. Through separation in drop tank, precipitation, emulsified oil, water and dust into the drop tank filter on it. The filtered into the tubing, the oil supply end cover and the pump cavity work.

the mechanical filter blocking mechanical pollutants inside the filter, purify the vacuum pump oil. The filter is usually connected to the pressure gauge to display the filter clogging. When the pressure increases, the flow of oil can not be normal. Filter plugging plug, filter should be replaced or cleaned.

rotary vane vacuum pump is usually a week to check your oil. According to the conditions of use oil change cycle. Usually, when because of the poor lubrication oil, oil decomposition or pollutants rise too much limit pump pressure is too big, need to replace vacuum pump oil.

when the exhaust valve, and through the separation medium and oil, and discharge from the vent, the combination of valve and pump, the pump work, part of the steam valve actuating eduction is expelled. Open oil crossroads, inflatable mouth closed. When the pump stops, the valve closed intersect, and air port is opened, the atmosphere from the air intake duct through the pump cavity filling damage the vacuum chamber, vacuum pump oil into the pump chamber.

Given the important role played by in ensuring proper functioning of pool cover drain pump, every individual must take an interest towards improving winter cover pump.
No more need to worry about the condition of your pool cover drain pump with , a water pump that helps in making your winter cover pump look pool cover drain pump like never before. Visit J&T INDUSTRY to know more.
