Q:What's the difference between an oil filter and an oil filter?
Filter oil filter oil filter is sometimes called, if you wanted a device, look at the oil filter, just want a simple small oil filter, we recommend that you can see the light oil filter on the market, or portable type oil filter.
Q:Centrifugal oil filter speed is not fast before, what is the matter?
Look at the belt and pulley. Is there any problem?
Q:Double barrel automatic electric heating centrifugal oil filter and horizontal oil
The effect of the two filters is different. It depends on what kind of oil you want to filter and how much you want to filter
Q:What kind of vacuum oil filter belongs to the fixed assets?
The fixed assets are divided into two categories: production, management and non production and management, so the vacuum oil filter belongs to the production and management category.
Q:What kind of oil filter is mainly used in the industry? What are the main uses?
Use:Mainly used for filtering treatment of high water content, serious emulsification of turbine oil, low viscosity lubricating oil. This machine is widely used in power plants and industrial and mining enterprises because of its obvious demulsification and dehydration effect. The circuit connecting the machine to oil equipment, can be carried out online, the demulsification in the steam turbine oil and low viscosity lubricating oil dehydration, removing impurities, achieve the purpose of comprehensive oil purification in the non-stop, without stopping production.
Q:Peanut oil centrifugal filter and vacuum oil filter which is good?
Research from the user perspective, centrifugal oil production machine is through the drum of high-speed rotation of the centrifugal force generated by the oil fine filter, need water treatment in oil dregs to absorb water becomes heavier, water quality after the diesel oil, the lightest, slag, water, oil natural three layer is formed on the inner wall of the drum rotating at high speed the. When to stop spinning oil bean out of the drum in the micro water surface, to attain the purpose of filtering, the filtered oil pure and clear, can be directly sold in cans or food. The centrifugal oil filter oil machine is the use of the high speed rotating from heart, the degree of pollution of lubricating oil of different oil, water and impurities by the effect of different centrifugal force and rapid separation. Production can be filtered 60-80 Jin each different
Q:Working principle and operation instructions of vacuum oil filter for oil press
Vacuum pump to vacuum tank air to form a vacuum, outside the oil under the influence of the atmospheric pressure through the entrance pipe into the primary filter, remove larger particles, and then into the heating tank, heated by 40 degrees to 75 degrees of oil through the automatic oil float valve, this valve is automatic control into the vacuum tank of oil import balance, after heating the oil whirl through the spray wing separating oil into a mist, oil and water in the rapid evaporation of water vapor into the vacuum pump and continuous inhalation of condenser.
Q:Method for using negative pressure oil filter
Negative pressure oil filter is vacuum oil filter.However, the negative pressure oil filters, which are matched with the oil press, are set up independently.
Q:The working principle of centrifugal oil filter
. Model of the power transmission speed of the drum diameter of slag when producing kg/H YTLY50- a 1.5KW belt drive 1800 rpm with 430mm not cover 200 slag YTLY50- B (chrome plated) 1.5KW belt drive 1800 rpm with 430mm not cover 200 slag type YTLY60-a 2.2KW belt start 1800 rpm with 500mm cover slag 300 YTLY60- B (chrome plated) 2.2KW belt drive 1800 rpm with 500mm not cover 300 slag centrifugal oil filter operation steps: pressing hot crude oil into the hot brine 1-1.5% fully stirred, its purpose is the dephosphorization, because phosphorus will have osteoporosis and other diseases of the body, so the content index of first national oil standard is phosphorus limited, H2O. NaCl (saline) and phosphorus P produce chemical reaction to form heavy salt Na2PO5 (sodium phosphate) and H2 (hydrogen) with the increase of fine particles suction make brine Water content becomes heavy;
Q:Difference between low speed and high speed of centrifugal oil filter
Then, the centrifugal oil filter can control the size of centrifugal force indirectly through the rotation frequency of the centrifuge, so as to realize different filtering effects. At high speed, the centrifugal force is great
