Because the SF6 gas itself contains moisture, the SF6 regeneration gas contains moisture, or the SF6 equipment is mixed with moisture during maintenance, inspection, and gas supply, or the insulating materials and adsorbents in the equipment fail, or the moisture in the atmosphere is sealed through the SF6 electrical equipment There are many reasons such as the weak link infiltrating into the equipment. Moisture is gradually contained in SF6 equipment.
We know that moisture has a great impact on SF6 gas and equipment. The amount of moisture in SF6 gas can directly affect the level of insulation strength of SF6 gas and whether the equipment can operate safely. Therefore, in SF6 equipment, we need to strictly control the trace moisture in SF6 gas.
In order to solve the problem of moisture in SF6 gas, we can use SF6 gas recycling machine to process SF6 gas in electrical equipment. The treatment process includes drying, moisture treatment, purification treatment, etc.
The SF6 gas recycling machine developed by YUNENG can vacuumize SF6 electrical appliances and GIS combined electrical appliances, and carry out recycling, purification, and inflation processing.
Oil Filtering Equipment are offered in a selection of shapes and size. While the end-goal is the specific same, there are a number numerous means to get normally there. In several arrangements, a prevent system enables this procedure to happen without having to shut off the machine that is obtaining the oil washed. It can be to be able to figure out if you ought to utilize crucial oil filter systems, however several of the normal signals consist of non-smooth treatment, extra sounds, as well as recognizable equipment scratching.
There are a number associated with pollutants that might happen in used oil, each from necessary oil break down along with outdoors aspects from the device. One of the most regular contaminants is actually metallic pollutants which do not begin in the industrial oil, but instead originate from device procedures. And there might be extra pollutants in the crude oil.
Oil Filtering Devices are utilized for a variety of reasons. In several setups, the main factor for oil purification would certainly be to maintain a good working condition. Unclean necessary oil can make equipment job lazily, slowly, and even result in a total break down. The machine break down is a very extensive arise from revealing devices in order to dirty needed oil for a long term time period. Eventually, this will certainly minimized the life-span of any type of kind of equipment. Needed oil filter systems will certainly assist prevent these kinds of concerns with arising to start with.
Along with safeguarding the products from infected oil, Oil Filtering Maker may offer additional functions also. Applying this systems, exactly the exact same oil may be cleaned up as well as reused several times which can decrease upkeep expenses.
There are lots of common techniques to execute Oil Filtration nonetheless bypass software program has ended up being the most regular. It offers all the advantages which purifying oil can create whilst additionally removing the dropped manufacturing which will certainly arise from requiring to shut down designs in order to modify their oil based.
During functioning of electrical devices, why we ought to use protecting oil purifier to purify dielectric oil. First of all, insulation materials are those materials that serve as an obstacle for power conduction. Insulation materials or simply electric insulation is of prime importance in area of utility of Electric appliances, be it a home device or an industrial equipment or electrical high voltage devices like the transformers, transmission lines, circuit breakers and like.
As the power levels scale up, the internal insulation degrees of devices, end up being extra crucial as well as vital element for the life of the tool. Tools like transformers and also motor-generators require a great insulation for robust electrical efficiency.
Water is perfectly existing in the environment in kind of water vapour. Insulation material like paper, insulating oils, timber etc have natural tendency to take in water. Water is an excellent conductor of electricity as well as if taken in by the insulation of the gadget damages the insulation.
When a gadget with a weak insulation is placed in procedure, the electric stress (voltage) may damage the insulation barrier for the existing leading to hefty inrush of electric current which the tool might not be able to hold up against and also eventually break down. In case the tool takes place to be a part of the system, this may result in failure of the system.
For improve the insulation performance, we can make use of vacuum shielding oil purifier to do proper purifying, so that it can ensure a proper insulation of the electrical gadgets to ensure non-failure of the electrical equipment.
Transformer insulating oils need to do purification treatment, as the impact of heat and electric area, the transformer oil in contact with oxygen is gradually oxidized to numerous oxides, alcohols, aldehydes, acid and so on, as well as type insoluble gum and sludge precipitation. These various oxides decrease the insulation performance of the transformer insulating oil,
Water and gas in transformer oil has 2 forms: dissolved water and gas (dew point) remain in electric systems. As well as totally free water and gas (above the dew point) are in shielding oil.
Because the system leak, untight seal, long-term warm lots, open storage space and so on, water and also contaminations airborne will certainly dissolved in oil.
Untreated transformer oil includes 50 to 60ppm water as well as 10% to 20% air, in order to reach requirement, it needs to eliminate water, gas and pollutants under state of rated vacuum as well as temperature level. The oil during usage ought to be regularly detoxified by vacuum Transformer Oil Purification System.
Dielectric strength of transformer oil mostly depends upon material of water, gas as well as impurities. Even brand-new oil storage and transportation will certainly has the gas and also water, so new oil also should be dealt with by Transformer Oil Purification System prior to filling up right into transformers.

A directional drilling simulator was constructed using are-formulation of first-principles classical mechanics in order to serve as a platform for advanced control design. Devoted focus was placed on erecting a modular result that would affiliate with an being Supervisory Control And Data Acquisition (SCADA) armature. Model complexity was confined to include only the features needed to make an immediate step change in tool face control performance through more accurate determination of torsional dead time and time constant values. Development of this simulator advanced the art of drilling robotization by erecting a foundation upon which inventors may design new control schemes using big data gathered in the ultramodern oilfield. This first-principles model is supported by theoretical expression of equations of stir that prisoner abecedarian geste of the drill string during both rotary and slide drilling operations. Esimtech line was fitted between check points using the Minimum Curvature Method, and asemi-soft-string drill string model was assumed. Equations of stir were deduced using energy styles captured in both Hamiltonian and Lagrangian mechanics and answered using the finite- element system. Flash dynamic results were attained using Newmark integration styles. A perceptivity analysis was conducted to determine which parameters played the most influential places in dynamic drill string geste for colorful functional scripts and to what extent those parameters told torsional dead time and time constant computations. The torsional time constant was chosen as a measure of correlation between case studies, due to the significant part this value plays in state-of-the- art tool face control algorithms. Simulation results were validated using field data collected from equipages using a SCADA system to operate in colorful shale plays in North America. Results from field tests were used to compare torsional time constant values calculated using manually- determined, simulation- grounded, and logical styles and probe directional drilling performance over a range of functional scripts. Simulation- grounded time constant computation results were constantly more accurate than analytically- determined values when compared to manually-tuned values. The first-principles directional drilling simulator developed for this study will be espoused by the being SCADA system in order to regularize and ameliorate slide drilling performance.
Vacuum Pumping System is a dual-use oil purification equipment. General users use this equipment to deal with the used oil filtration, impurity removal and decolorization, etc., to get new oil that can be used, which can save cost and facilitate the use of oil. In fact, vacuum oil filter has another function, that is, vacuuming.
The use of vacuuming system in oil filter machine refers to closing the filtration system of the whole equipment and opening the vacuuming system. In both systems, the equipment can be vacuumed by closing the specified valve, removing the dust plate from the vacuuming system and connecting it to the pipe.
Of course, the use of vacuum oil filter vacuum also has a disadvantage, is the distance of the vacuum pipeline. The vacuumizing distance of general pipes should not be more than 15 meters, otherwise the vacuumizing effect will not be achieved (except for special vacuum pipes).
In order to ensure the quality of new oil and running oil, purification treatment is a common and important means. Transformer oil purification after purification can remove moisture on one hand, improve the dielectric strength of insulating oil and turbine oil demulsification degree, and reduce the oil degradation rate, on the other hand may also remove mechanical impurities that mix oil and oil after the degradation of the sludge generated by sediment, to avoid the oil system has been blocked due to bad heat dissipation, can prevent the abrasion of mechanical impurities on the equipment.
The pretreatment methods of transformer oil are generally divided into three kinds, sedimentation method, filtration method (pressure type and vacuum type) and centrifugal separation method.
Sedimentation method is also known as gravity sedimentation method, it is the use of turbidity liquid solid and liquid particles by gravity and sedimentation principle to remove impurities and water in the oil. Purification by sedimentation method is simple and easy, and does not need more and more complex equipment. But this method of purification is not complete, can only remove most of the water in the oil and can naturally settle down the mixture. Therefore, the general settlement method can only be used as a pretreatment. The pre-treated oil shortens the time, ensures the purification quality and reduces the purification cost.
Pressure filter paper filter method, pressure filter method using equipment called pressure filter, also known as frame plate oil filter. It is the use of gear oil pump pressure, so that the oil through the oil filter paper with adsorption and filtration, the transformer oil water, fine impurities and water-soluble acid substances removed, so that the transformer oil can be purified. The following points should be paid attention to when using pressure type oil filter.
Filter paper should be dried before use, so as to improve the performance of filter paper to absorb water. At the same time, the filter paper should be especially careful when baking to avoid fire. If the transformer oil contains a lot of water and impurities, the oil should be treated by sedimentation method or centrifugal oil filter, and then filtered by pressure type oil filter. During filtration, the fiber of the filter paper should be avoided from being brought into the oil. Within 5 ~ 10min of the beginning of oil filtration, the oil drawn out by the oil filter should be re-directed to the inlet of the oil pump for circulating filtration. In order to reduce viscosity and improve filtration speed and efficiency, the oil temperature should be increased to 40 ~ 45℃.
Vacuum filtration method is by means of vacuum oil filter, that is, transformer oil atomized in high vacuum and not too high temperature, out of the trace water and gas in the oil. Because the vacuum oil filter also has a screen, it can also remove some solid impurities. It is not only more economical than the pressure filtration method, but also has a high degree of purification and efficiency. It can release the trace water in the oil, maximizes the strength of the insulating oil, and reduces the oil consumption. When the flash point of transformer oil drops and precipitates combustible gas due to failure, the flash point can be restored by vacuum purification treatment.
Centrifugal separation method is the use of oil and water and impurities of the density of three different in the centrifuge rotating centrifugal force produced by different separation and purification. Among them, oil is the lightest and gathers in the center of the rotating drum, while water is more dense and dumped in the outer layer of the oil. The solid impurities in the transformer oil are dumped in the outermost layer, so as to achieve the purpose of separation and purification. Using this method to purify oil efficiency is relatively high, where the oil contains more water and mechanical impurities, can be used in this method. Especially to remove impurities such as slag and carbon particles in oil, the effect will be better, but this method also has limitations, that is, only suitable for removing impurities larger than oil density.
On a modern merchant ship, there are hundreds of machines that make up the ship's power system and auxiliary systems for daily operations. In order to ensure safe production and operation, it is necessary to ensure the smooth and reliable operation of machinery and equipment, and lubricating oil is extremely important to the operation of machinery and equipment, and the quality and technical indicators related to lubricating oil are also one of the measures to evaluate the performance of machinery and equipment. The main function of marine lubricating oil is to form an oil film to reduce friction and noise of mechanical moving parts, to remove the heat generated by cooling, and to protect the metal from corrosion. Lubricating oil does not actually wear, but its lubricating quality will affect its quality and life due to pollution such as moisture, mechanical wear, fuel oil, combustion products, etc. However, the common mechanical equipment failure problems caused by unpurified lubricating oil over time include reduced fuel efficiency, reduced load capacity, acid corrosion of metal parts, bacterial corrosion, etc., and severe cases such as diesel crankcase explosions and even crew lives. Casualties and damage to ship property. Therefore, it is necessary to maintain the relevant performance characteristics of lubricating oil, such as viscosity, alkalinity, anti-wear, anti-oxidation, cleanliness and dispersion, stability, etc., to ensure that machinery and equipment are in good condition, reduce machine damage and failure, and ensure the safety of ship navigation . To this end, we need to properly separate and purify the lubricating oil through the Lube Oil Purifier to maintain the quality of the lubricating oil to prolong its service life, and at the same time, it can save energy and reduce consumption and reduce operating costs.
At present, in addition to filtration, condition monitoring, and regular sampling and testing to control the quality and technical indicators of the system lubricating oil of the main propulsion power unit and the generator diesel engine, the key is continuous purification during operation to maintain the quality of the lubricating oil and prolong the service life. (The lubricating oil of some other auxiliary or small mechanical equipment is ensured by filtering, monitoring the quality condition and replacing it if necessary)
What is a lubricating Lube Oil Purifier
A lubricating Oil Purifier is a mechanical device used to separate impurities (such as water and solid particles, etc.) in lubricating oil. There are three ways to purify lubricating oil: centrifugal method, filtration method, and merger method. In this article, we will discuss centrifugation, as it is the most commonly used method for decontamination of lubricating oils on ships.
Reasons why centrifugation is superior to other purification methods: removes water and solid impurities in a single operation; small particles can also be cleaned effectively; requires minimal or very low maintenance (which in turn increases process uptime); low installation costs, equipment life long. Therefore, the centrifuge is the preferred equipment for lubricating oil purification. It separates solid impurities and water by centrifugal force according to the density difference of the two liquid substances.
The working principle of centrifugal Lube Oil Purifier
Centrifuge is one of the most important auxiliary equipment on ships. Its working principle is to separate oil, water and impurities of different specific gravity by centrifugal force generated by high-speed rotation.
The traditional method is gravity settling separation, but it takes time because gravity is the only force for settling. However, in the centrifuge, the centrifugal force field is thousands of times more efficient than the gravitational field of oil, water, and impurities, and the purification time is shorter and the purification quality is higher. Based on the centrifugal purification principle, the unpurified lubricating oil is introduced into the separation cylinder of the Lube Oil Purifier through the oil supply pump for centrifugal motion, and the impurities with the highest density are thrown to the outermost periphery, and the slag is removed regularly by manual or program control. The water is guided and discharged in the middle, and the oil with the least density flows inward from the outlet near the rotating shaft and is discharged back into the mechanical system or a suitable oil tank.
