Q:How does the 25 litre oil purifier determine flow?
The parameters to be considered: 1. filter oil flow (this is the most important, according to your company's oil situation to determine the appropriate flow of oil filter,
Q:Oil filter ZLA-20! During the test process! Foam
Addition of foam, which we have added, has no effect on the oil.
Q:Where has the waste lubricating oil to come in, it is the oil filter of the finished oil
But you call into oil means nothing more than to sell, not in repeated use, the oxidation of colored substance is soluble in oil cannot be filtered through ordinary oil filter, that is filtered to decolorization. You said the so-called "waste oil into refined oil" is not possible, to become the so-called refined oil, must decolorization, some of the products of domestic only through clay, activated carbon and other similar material to absorb, but even if the color change can not be used directly, through adsorption oil additives has been lost only, from the new processing additives can become a refined oil
Q:How do oil press oil from froth
Although it looks clear, there are still impuritiesWhen you stir fry, add water evenly,
Q:Operation description of turbine oil vacuum oil filter?
Because it is located in a position similar to that of the steam seal, it is easy to enter steam (steam condenses into water in the oil). Cause there is middle water cut,
Q:How to solve the problem of oil leakage in the centrifugal oil filter?
Causes of oil leakage:Filter 1. centrifugal oil filter in the case not properly installed, cause when the machine is running into oil in crude oil2. there are many impurities in oil, and the oil outlet is blocked
Q:Working principle of vacuum oil filter
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, after heating the 40~75 C oil through the automatic oil float valve, the valve is automatically controlled in a vacuum tank the amount of oil import balance. The heated oil is rapidly rotated through the jet wings to separate the oil into a half mist. The water in the oil evaporates rapidly into steam and is pumped into the condenser continuously by vacuum pumps
Q:What is the reason for the fuel injection of the turbine vacuum pump?
The vacuum is too low, there may be reasons: there is a leak in 1 systems, mainly to the vacuum pump vacuum tank and the pipeline leakage; 2 kinds of oil, too much water into water vapor in vacuum environment, vacuum pump caused by excessive load, turn the small oil pump outlet valve; the 3, vacuum pump.
Q:Which is more practical, plate pressure type oil filter and multi-function oil purifier? What are their advantages and disadvantages?
For example: DYJ series multifunctional lubricating oil purifier Chongqing Wanmei according to the characteristics of various types of oil kinematic viscosity, flash point index difference, a common type of specialized development and production of multifunctional lubricating oil purifier, suitable for lubricating oil of various types, different grades of effective purification. Is the industrial and mining enterprises to purify all kinds of lubricating oil ideal equipment. The two-stage or multi-stage vacuum purifier is more efficient.Use:Widely used in hydraulic oil, hydraulic transmission oil, gear oil, gasoline engine oil, diesel engine oil, compressor oil, refrigerator oil, heat treatment oil and so on. The utility model can rapidly remove moisture, gas and mechanical impurities in oil, flash out the light acid and light hydrocarbon, improve the quality of the oil, and restore the use performance of the lubricating oil. Ensure the normal operation of power system, hydraulic system and lubrication system.
Q:How does the vacuum oil filter remove moisture and loss?
Because the water diversion filter uses enhanced hydrophobic interaction technology, improve the oil-water interface, the tiny drops of oil in the accelerated motion, and coalesce into large droplets separated out from the oil, the precipitation in the water reservoir. Then enter the three-dimensional vacuum flasher to remove impurities in oil, in the spray device under the action of the dispersed oil mist sprayed into the three-dimensional flash Bauer ring, forming a thin film of oil (0.025mm thickness), oil film curve downward, greater aeration area and aeration time lag process, separation process and demulsification, dehydration and degassing of the full. A mixture of vaporized water vapor, light hydrocarbons, etc gas enters a water vapor separator
The company has a large number of both ability and political integrity technology, production, sales and management personnel. Also has a number of well-trained and experienced staff. Company has strong technical strength, production ability, mainly the production of high-speed equipment bag two layer, three layer coextrusion film blowing machine production lines in various fields.
