Stainless steel filter element how to maintain

Stainless steel filter element is very widely used in our daily life, so do you know how to maintain stainless steel filter element?1. When maintaining, remove the hydraulic tank refueling cover, filter cover, detection hole, hydraulic tubing and other parts. The hydraulic system oil channel should avoid dust when exposed, and the disassembly part should be cleaned thoroughly before opening.When removing the hydraulic tank refueling cover, remove the soil around the oil tank cover first, remove the debris remaining in the joint after the oil tank cover is loosened (do not rinse with water to avoid water infiltration into the tank), and then open the oil tank cover after confirming the cleaning.If you need to use rubbing materials and hammers, you should choose a special hammer that does not drop fiber impurities and rubber on the hitting surface.Hydraulic components, hydraulic hose to be carefully cleaned, with high pressure air dry after assembly.Choose genuine filter element with intact package (if the package is damaged, the filter element may be unclean even though it is intact).Oil change at the same time clean the filter, before the installation of the filter element should be used to wipe the material to carefully remove the filth inside the filter shell.

Two, ensure that the hydraulic oil is not used at high temperature;The oil will soon be oxidized at high temperature;The air filter on the hydraulic station should be used to filter particles and filter water, which are sold on the market.

Three, precision filter, hydraulic oil filter makes the oil pollution to keep for a long time in the NAS < 8, the equipment own filter generally poor accuracy, can guarantee the cleanliness of hydraulic oil, because of the hydraulic station capacity limit only 5 um, dirty and accuracy is often more than the size of the filter, scientific rules general pollution requirements of hydraulic station control in the NAS is less than a magnitude 8,For equipment with servo mechanism, the requirement is higher, less than 7 level. If you have removed the servo valve, then you will understand everything, why the hydraulic oil pollution must be controlled so high.Buy a precision oil filter for online filtration, and now the precision of some filter elements has reached 0.1um;4, centrifugal dehydration/vacuum dehydration (for the oil station with water).As long as it is well controlled, generally such as Mobil, Shell, etc., it can be used for 5 years, but the premise is that there are more fake oil now.

Four, stainless steel oil filter element is used in the hydraulic system, used to filter the particulate debris and rubber impurities in the system, to ensure the cleanliness of the hydraulic system.Hydraulic oil must be filtered when refueling, refueling tools should be reliable and clean.The filter at the fueling port of the hydraulic tank cannot be removed to increase the fueling speed.Oil personnel should use clean gloves and work clothes.

Five, the cleaning oil of the hydraulic system must use the same brand of hydraulic oil as the system used, the oil temperature is between 45~80℃, and the impurities in the system will be taken away as far as possible with a large flow.The hydraulic system should be repeatedly cleaned more than three times, after each cleaning, when the oil is hot, it will all be released out of the system.Clean the filter after cleaning, replace the new filter element and add new oil.
