Use
The explosion-proof vacuum oil filter is specially used for the operation of petroleum, oil-chemistry, coal mine, chemical industry, power plant, power station, railway, mine, machinery industry, etc. where there is flammable and explosive substances. It can treat the polluted oil and make it improved as good as that meets the demands of the State Standard. The kinds of oil include isolating oil (such as transformer oil, circuit breaker oil, mutual inductance device oil, capacitor oil, cable oil, etc.), turbine oil, hydraulic oil, lubricating oil, heat conductor oil, quench oil, gear oil, freezer oil, compressor oil. The treated oil can resume the previous operative function. It can be used on-line by serial connection with safety. This kind of machine can be used to purify the transformer oil, turbine oil, compressor oil while the working assemble is still operating on normally without stopping production, without power off, without stopping the machine. The oil treated can be good enough to use, thus, to make the equipment and oil quality workable condition last longer.
Characteristics
We are the only enterprise to enjoy the qualification certificate of explosion-proof vacuum filter production in China. It can be used in the special industrial and mine environment where there are some substances prone to being on fire and/or explosion. The special heat exchanging device can make most of the vapor from the hot air drawn out change into water drops, thus, to avoid it going into the vacuum pump. Therefore, the vacuum pump oil will not be emulsified during the operative process. It will not erupt out, either. Thus, the 2 big problems that were very troublesome before have been successfully solved. The vacuum pump?s service life has greatly been extended. It is in the position of leading the way in the similar technology in China. All the parts of this machine have been treated with phosphorization.
These serial products are of high efficiency, low-energy consummation, easy operation, and easy maintenance. They are small in size and light in weight and easy to move. They are the right products to replace the plate-frame oil filter, centrifugal oil filter and the old-style vacuum oil filter.

Tech parameters

Use and characteristics
The equipment of HYF device can separate the light oil (burning oil) from all kinds of mixed lubricating oil. It is used to purify the parts washing oil (such as kerosene, diesel, and gasoline) in aviation, spaceflight, vehicle, motorcycle, bearings, manufacturing industry, precision tool making and processing industry, etc. The color difference between the oil treated before and after can be within only 1%. The PH value reaches the standard of new oil (grade 6). The washing oil, such as aviation kerosene, used in bearings manufacturer and gears manufacturer, is often mixed with much lubricating oil, such as rust-resisting oil, grinding oil, etc. The HYF separating device of this Institute can surely be used to separate them, meanwhile, to separate the moisture content, mechanical impurities, sediments and corrosive materials efficiently (separating degree reaching 100%). The cost to treat one ton of oil is only within 70 RMB Yuan. And it can be used repeatedly. The selling price of this device is much low. It is simple and easy to operate. The rate of recovery can reach 98% of the waste oil (except the oil mixed with phosphor and super fine liquid).

Characteristics

1. High efficiency in dehydration and emulsion breaking. It can easily separate the large quantity of water from oil and eliminate the micro moisture content in oil as well.
2. High efficiency in filtering and purification. It can quickly make the worsened, polluted oil back to the quality as good as that of the controlled standard of turbine oil polluted degree for normal operation, with the particle-size
3. High safe automatic operation without breakdown. It does not waste oil when purifying oil in succession. No leaking as is connected by stainless steel valves.
4. It is simple and easy to control the whole machine with safe, advanced, and reasonable design. The advanced magnetic automatic compensation system for oil level avoids the oil pump working in vain or oil escaping that occurred very often in other common oil filters. The automatic controller for pressure is installed. When pressure is too strong, it gives warning and stops automatically. Then the self-discharge vacuum device works. The electric valve can close itself to avoid the possibility of oil backward into or escaping from the generator. It is on-line safe operation without manpower watching by.

Use
JT serial oil purifying machines for turbine oil can be used for purifying the turbine oil of generating set and transformer oil. They can be used to deal with hydraulic pressure oil that is widely used in metallurgical industry, petroleum industry, chemical industry, mine industry, railway, aviation and spaceflight industry, ship and vessel industry, machinery industry and so on. It can be used to purify the machinery low-viscosity lubricating oil.
This kind of machine can efficiently dehydrate the emulsified oil that has been seriously polluted by water. And the vapor, acid matter, saponin, gluey color matter and mechanical impurities can be eliminated from the polluted emulsified oil as well. The emulsified oil after purification this way can become tranquil and clean. Thus, it proves quite a success to solve the problem as to water elimination and oil purification for generating set that has been very troublesome before.
This machine can be used not only for dehydration, emulsion breaking, filtering and purification, but also for on-line operation by series connection. It can be used to remove the solid impurities from the pipes of generating set and devices at any time when necessary according to the second need of the generating set.

Use
This equipment is used to purify the used machinery oil, hydraulic oil, compressor oil, motor oil, mediate-load gear oil, cooler oil, steel rolling oil, quench oil, flash swift quench oil, etc. in mine, metallurgical industry, machinery, chemical industry, rubber industry, instrument, traffic, petroleum drilling and exploring, construction ceramics, precision pressure casting, etc. The oil to be treated is from No.5 to No.1500 that is in high, mediate or low viscosity in movement. This kind of machine is specially used to purify the oil from cement, chemical and fertilizer production. Sometimes the oil to be treated has as much as 70% impurities in it, such as aqueous acid, ammonia acid, carbon, dust-sand-clay, moisture content, etc. The water separated form the oil treated by this equipment has different colors: the water color can be milk white if the aqueous acid in it is serious. The color can be blue if the ammonia acid in it is very much. The color can be white if the oil has been seriously polluted by alkalis. The waste water from the treated oil has much snow-like floating matter on it. This equipment takes only the physical principle methods to treat the oil. It takes no chemical agent for purification. Therefore, the oil treated remains its original color.
Characteristics

1. The vacuum oil filter researched and developed by this Institute can treat low and high viscosity lubricating oil in various kinds. It needs no special conditions on environment except electricity and waste oil. The waste oil can be treated everywhere and whenever. The operation is simple and easy. The maintenance for the equipment is simple and easy, too. And the cost is very little. The electricity consummation is only 50% of the whole machine in summer and 60% in winter.
2. When using this equipment to deal with any polluted oil, no chemical agent is needed. It is purely mechanical and physical purifying methods. Thus, the oil treated remains the same nature and function.
3. Wind cooling method is adopted. Therefore, the vapor separated from the polluted oil can be condensed into liquid in only 2 seconds and discharged completely soon. Thus, the water source is protected as the water cooling method consumers much fresh water (it is special suitable for treating the high-viscosity oil and the water-in-oil that is quite abnormal.)
