How long is the vacuum pump of the rotary vane vacuum pump oil in _ at a time

vacuum pump oil in use process, due to oxidation, emulsification and the outside world with all kinds of impurities such as reasons, some of the oil deterioration, when bad ingredients and impurities to a certain extent, change the color of the oil, viscosity and acid value increased, the precipitation of insoluble resin material, higher vapor pressure of the vacuum pump oil, the performance deterioration. Oil pump at this time do not continue to use the new pump oil must be replaced.

in order to prevent the dust, of the vacuum pump oil in material with pump oil into the water pump chamber, for some serious pollution process, before the medium is pumped into the pump should be a continuous filtering device, is used to filter most of the pollutants, And a small area of the filter can filter dust and impurities and contaminated oil, sink to the bottom of the main tank, through the return pipe into the drop tank. After separation, precipitation and emulsification of oil, water, dust and impurities into the bottom of the drop tank, by the discharge valve is released on a regular basis. While relatively clean oil from drop tank into the tubing back into the oil cavity, supply end cover and pump chamber work.

rotary-vane vacuum water pump are periodically check the oil quantity interval length different due to different working conditions. Usually is pumped medium dust, moisture, water pump more frequent start times environment ( Such as: artificial stone, resin handicraft, vegetables, packaging, etc) Per shift, should check; A single start time is pumped medium clean, long use environment ( Such as: vacuum coating industry, etc) And check the oil amount of time can be extended in due course. Oil change interval also depends on the working conditions, generally because of poor lubrication oil pump, oil decomposition or pollutants too much running performance, just need to change the new oil. Put oil tips:

new vacuum pump oil, the first open the discharge valve oil drain; As much as possible for the old oil line, close the discharge valve and boot for a few seconds, open drain valve continue to drain after downtime, until the clear to close the valve.

at atmospheric skills:

vacuum pump in the long run, the accumulation of pollutants is easy to cause performance degradation, appear 'smoke' phenomenon. Blunt atmospheric purpose is to remain within the pump discharge of pollutants washed away.

after the row of qing dynasty old vacuum pump oil, boot and quickly from the air intake into 0. 5 ~ 2 kg old oil *, Concrete pouring oil see note) , 10 seconds after downtime and promptly open the discharge valve oil, repeat for 2 ~ 3 times. Last atmosphere should be poured into new oil, if the discharge of oil muddiness, indicate that the pollution is outstanding, within the pump may continue to the above operation, until the discharge oil clean and transparent. At that moment, from oil refueling refueling to mirror the specified height, close the air intake and boot for 20 minutes, running may continue to be put into use. Discharge of the old oil can let stand for 1 ~ 3 months, the upper clean oil can recycle.
