Q:How do oil press oil from froth
Although it looks clear, there are still impuritiesWhen you stir fry, add water evenly,
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:How about the rental fee for vacuum oil filter?
This is not easy to say, general oil filters are to buy a better, after all, waste oil is often a loss, as long as the production will inevitably produce waste oil
Q:What's the problem with vacuum oil filter? We have a project abroad
Vacuum oil filter which house is good? Do not understand what you mean, I can only according to the current oil filter industry some of the circumstances to answer you.The price of 1, the vacuum oil filter: different brands, different manufacturers, different configurations, different type, size, price is not the same; the price of domestic configuration vacuum oil filter, vacuum oil filter joint configuration and the full import configuration of vacuum oil filter is certainly not the same.
Q:What is the return of the oil filter?
That estimate the filter has a problem, filter oil machine is not set up, or filter plug. Or the connection is wrong
Q:What is the working vacuum in the oil filter?
Therefore, the so-called "working vacuum" is the vacuum filter oil function, the completion of gas-liquid separation and oil-water separation function vacuum control range.
Q:What is the difference or connection between the oil filter and the oil filter?
All belong to the fluid filtration industry, the difference is that the oil filter is the filter equipment, and the filter is at most a filter device
Q:When the centrifugal oil filter is used to filter peanut oil, the oil color is black and cloudy. What's the matter?
The centrifugal filter can filter the cooked peanut oil. Raw peanut oil, too low temperature, filtration effect is not good
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:Want to produce oil filter, that is to filter the hydraulic oil machine
4 answersForget it!! Want to do well in the oil filter, now demand plummeted, large manufacturers, like our Chongqing runneng oil filter, oil filter such enterprise development more than 10 years machine get up have labored, small factories had more bad days!
