Selection, use, replacement and storage of vacuum pump oil for vacuum oil filter.
2019/8/1??????view:
1. Change oil in time: After a period of use, the nature of pump oil will change. For example, mechanical stress leads to cracking, oxidation denaturation, chemical reaction denaturation, water vapor or condensable gas integration leads to hydrolysis and emulsification, chemical substance dissolution leads to property change, dust deposition leads to viscosity increase, etc. In this case, the condition of pump oil can no longer meet the needs of normal operation of vacuum pump, resulting in worse vacuum, difficult start-up, pump temperature rise, noise increase and other phenomena. At this time, new pump oil needs to be replaced in time to ensure the normal operation of vacuum pump and prolong the service life of pump. If it is not replaced in time, it will lead to wear and tear of pump parts, corrosion of pump parts, shorter service life, and even damage of pump in serious cases.
2. Use and maintenance of vacuum pumps related to pumps
2.1 Prerequisites for Fault-free Operation of Pumps
2.1.1 Dust and particles entering the pump may cause pump failure.
2.1.2 Vacuum pump can not be used to transport liquid.
2.1.3 Reactive or corrosive chemicals in the load can denaturate the pump oil and erode the material of the pump.
2.1.4 Corrosion, precipitation and cracking of pump oil will lead to failure.
2.1.5 When condensable steam is contained in the process, in order to avoid corrosion caused by dissolving in the pump oil after shutdown, the intake valve should be closed and the gas ballast should be opened to continue running for 30 minutes.
Under the premise of 2.1.6 pump gas-opening town, only the allowable amount of water vapor can be treated; if it exceeds the capacity, it is recommended to use condenser to pre-capture.
2.1.7 is suitable for long period oil exchange.
2.1.8 Use suitable pump oil.
2.1.9 Check oil level regularly.
2.1.10 to reduce load temperature.
2.1.11 Oil filters are used to purify the oil and separate the dissolved process media.
2.2 For special applications, when oxygen, halogen, polymeric substance, crystalline substance, resin-oriented substance and solvent are removed, some lubricants suitable for process can be selected.
Vacuum filter vacuum pump oil warning!
When the oxygen content in the process gas mixture exceeds the standard oxygen content in the air, that is, when the oxygen volume percentage is more than 21%, inert perfluoropolyether similar to PFPE should be used as the working fluid of the pump.
Under the condition of high oxygen content, mineral-based lubricants are more prone to oxidative denaturation, and the decomposition of mineral-based lubricants to produce low ignition point products is dangerous. Therefore, close observation of oil properties is required; in actual use, very frequent oil change cycles may be required.
2.3 Vacuum Oil Filter for Vacuum Pump Oil of Vacuum Oil Filter
We can provide a variety of oil filters, including:
2.4.1 Mechanical oil filter for separating dust particles, crystalline sediments and sludge.
2.4.2 chemical filter, using the adsorption properties of activated alumina to separate the solutes in oil.
2.4.3 Choose different kinds of separators at the intake end to prevent the process medium from entering the pump.
3. Storage conditions of vacuum pump oil for vacuum oil filter:
3.1 Use sealed original containers.
3.2 Avoid direct sunlight.
3.3 Store in a dry and clean enclosed room.
3.4 Storage temperature: 10-35 C.
Under suitable storage conditions, the shelf life of the original unopened standard oil is three years. For unsealed original containers: If the environment is not suitable, the storage period will be shortened. After the container is opened, dust, pollutants and water vapor must be avoided from entering the container. Oil should be put into use as soon as possible. The storage life of oil will be shortened after opening.
