三滤 Perkins diesel engines in the United Kingdom have three types of filters: air, oil, and fuel, which are generally called " three filters . " They are responsible for filtering the media in the engine's intake system, lubrication system and combustion system.
Perkins diesel engine air filter
( 如纸滤芯 ) 将空气中的杂质分离出来的滤清器。 It is a filter that separates impurities in the air through a dry filter element ( such as a paper filter element ) . ( 含轿车、微型车 ) 所用的空气滤清器一般为单级。 The air filters used in light vehicles ( including cars and mini cars ) are generally single-stage. [1] 形状有扁圆或椭圆及平板式。 Its [1] shape is oblate or oval and flat. The filter material is filter paper or nonwoven fabric. The end of the filter element is covered with metal or polyurethane, and the shell material is metal or plastic. 99.5% At the rated air volume flow rate, the original filtration efficiency of the filter element should not be less than 99.5% . Due to the harsh working environment of a heavy vehicle, its air filter must be the majority. ( 如叶片环、旋流管等 ) ,用于滤除粗大颗粒杂质,过滤效率在 80% 以上,第二级细滤是微孔纸滤芯 ( 一般称作主滤芯 ) ,其过滤效率达 99.5% 以上。 The first stage is a swirl type pre-filter ( such as a blade ring, a swirl tube, etc. ) , which is used to filter out coarse particles and the filtration efficiency is above 80% . The second stage fine filtration is a microporous paper filter ( generally called the main Filter element ) , its filtration efficiency is over 99.5% . There is a safety filter element behind the main filter element, which is used to prevent dust from entering the engine when the main filter element is installed and replaced, or when the main filter element is accidentally damaged. The material of the security core is mostly a non-woven fabric, and some also use filter paper.
Perkins diesel engine oil filter
  

effect:
Perkins diesel engine oil filters are located in the engine lubrication system. Its upstream is the oil pump, and its downstream is the parts that need to be lubricated in the engine. Its role is to filter out harmful impurities in the oil from the oil pan, and supply clean engine oil to the crankshaft, connecting rod, camshaft, supercharger, piston ring and other motion pairs to play a role of lubrication, cooling, and cleaning. Extend the life of these parts.
kind:
Perkins diesel engine oil filters are divided into replaceable, spin-on, and centrifugal according to the structure; they can be divided into full-flow and split-flow according to the arrangement in the system. Filter materials used in oil filters include filter paper, felt, metal mesh, and non-woven fabrics. Before the 1980s, the engine oil filters used by China National Engines were mostly replaceable. In this type of filter, the filter element and other parts, such as springs, seals, etc., are placed in a metal casing, and the casing element and the like are connected and fixed to a metal filter seat through a pull rod. Its advantage is that the use cost is low, and only the filter element needs to be maintained and replaced regularly. The disadvantage is that there are too many sealing points, maintenance and replacement of the filter element may be missing parts, which is easy to cause leaks, and it is laborious to replace. Since the early 1980s, the Bengbu Filter Plant was the first in China to introduce a spin-on filter production line from Italy, and the spin-on filter has gradually been approved for use by domestic OEMs. The characteristics of this filter is that there is only one check valve, bypass valve, and sealing point in the interior. The overall replacement greatly improves the tightness and is easy to replace. The filter element material mostly uses imported filter paper, so the filtration efficiency is high. Low flow resistance and long life. At present, all domestic cars use this type of oil filter. Most of the mini cars and large, medium and small passenger cars, light and medium trucks, and some heavy trucks and agricultural vehicles use spin-on oil. Filter. The centrifugal oil filter has a rotor sleeved on a shaft, and has two nozzles with opposite spraying directions. When the oil enters the rotor and exits from the nozzle, the rotor rotates quickly, so that the oil in the rotor body is cleaned. The impurities in the oil are centrifuged to the inner wall of the rotor, and the oil from the nozzle flows back to the oil pan. * ,没有需要更换的滤芯,只要定期拆卸转子,清洁沉积在转子壁上的污垢又可重新使用。 The characteristics of the centrifugal oil filter are stable performance, structure can be * , there is no filter element that needs to be replaced, as long as the rotor is regularly disassembled, the dirt deposited on the rotor wall can be reused. Its life can be equivalent to the engine. Its disadvantages are its complex structure, high price and bulk, etc., and it has high technical requirements for users. Full-flow oil filters, such as the replaceable, spin-on, and split-centrifugal type described above, filter all the oil that enters the system. 5%-10% 的机油。 The split filter filters only 5% -10% of the oil supplied by the oil pump . Split-flow oil filters are fine filters, which are generally used in combination with full-flow filters. Most low-power engines only use full-flow filters, and diesel engines with larger powers often use full-flow plus split-flow filtering devices.


What are the oil filter requirements for filter paper
0 300 度不等,在剧烈的温度骤变下,机油的浓度也发生相应改变,这会影响到机油的过滤流量。 The oil filter has higher requirements for filter paper than the air filter, mainly because the temperature of the oil varies from 0 to 300 degrees. Under severe temperature changes, the oil concentration also changes accordingly, which will affect the Filtered flow of oil. The filter paper of high-quality oil filter can filter the impurities under the drastic temperature change to ensure sufficient flow.
The role of different types of oil filters in lubrication systems
The oil filter in the lubrication system in order to make the lubrication system oil flow through unobstructed, to avoid scratches and burrs on the surface of the parts, the oil must be strictly filtered before being sent to the friction surface. In order to achieve the desired filtering effect without increasing the resistance of the oil circuit, a coarse filter is generally connected in series with the main oil passage, and a fine filter is connected in parallel with the main oil passage.

、浮子式机油集滤器,为使机油泵很好地工作,必须把润滑油中的大颗粒杂质在进入机油泵之前除掉,这个任务由集滤器承担。 1. Float type oil filter, in order to make the oil pump work well, large particles of impurities in the lubricating oil must be removed before entering the oil pump. This task is borne by the filter. It is connected to the oil inlet of the oil pump. When the oil pump is working, the oil is sucked in through the slit between the cover and the float. After filtering out coarse impurities through the filter screen, it enters the oil pump through the oil pipe welded to the float. When the filter is blocked, the suction of the oil inlet pipe increases, and the bad port is overcome by the filter's strength to leave the cover, and the oil directly enters the suction pipe from the ring port without passing through the filter.   

、粗滤器串联在机油泵和主油道之间,故又称之为全流式滤清器,用来清除机油中较大的杂质。 2. The coarse filter is connected in series between the oil pump and the main oil passage, so it is also called a full-flow filter, which is used to remove larger impurities in the oil. At present, paper filters are more commonly used at home and abroad. It is mainly composed of upper cover, housing, paper filter element and bypass valve. When the engine is running, the lubricating oil with pressure is sent around the filter element and into the cavity around the filter element. The larger impurities in the oil are blocked by the paper filter element, and the clean lubricant enters the inner cavity of the filter element and then passes through the oil outlet. Enter the main oil passage of the cylinder block.

、细滤器:其作用是滤掉润滑油中更小的杂质,通常与主油道并联,有离心式和纸板式两种。 3. Fine filter: its role is to filter out the smaller impurities in the lubricating oil, usually in parallel with the main oil passage, there are two types of centrifugal and cardboard.

、离心式细滤器的结构:空心的转轴固定在外壳上,转子体及端套连成一体,座落在止推轴承上,可绕转子轴自由转动。 4. The structure of the centrifugal fine filter: the hollow rotating shaft is fixed on the housing, and the rotor body and the end sleeve are connected into one body, which is seated on a thrust bearing and can rotate freely about the rotor shaft. The compression nut fastens the rotor cover and the rotor body, and the upper part is compressed by a spring to limit the axial movement of the rotor. The lower part of the rotor is equipped with two nozzles which are opposite to each other. When the engine is running, a small part of the oil is pumped from the oil pump and enters the filter through the oil port. 9s 千帕时,进油限压阀关闭,细滤器不起作用。 When the oil pressure is lower than 9s kPa, the oil inlet pressure limiting valve is closed, and the fine filter does not work. 98 千帕、限压阀逐渐开启,机油经转子轴中心孔, When the oil pressure exceeds 98 kPa and the pressure limiting valve is gradually opened, the oil passes through the center hole of the rotor shaft. Spray out from under the oil hole. Then it enters the rotor body through the oil hole and sprays out from the two nozzles, so the reaction force of the spray pushes the hand to rotate. 294 千帕时,转子的转速可达 5000r/min 以上,转子内腔润滑油中的杂质的比重比润滑油的大,在旋转离心力的作用下,被抛向转子壁,并附盖在壁上。 When the oil pressure rises to 294 kPa, the rotation speed of the rotor can reach more than 5000r / min . The proportion of impurities in the lubricating oil in the rotor cavity is greater than that of the lubricating oil. Under the action of the rotating centrifugal force, it is thrown to the rotor wall, and Attached to the wall. The clean lubricating oil at the center enters the two nozzles from the center and continuously sprays outwards, and the lubricating oil flowing back flows to the lower crankcase.
  

effect:
Its role is to filter out harmful particles and water in the fuel gas system of the engine to protect the oil pump nozzles, cylinder liners, piston rings, etc., reduce wear and avoid clogging. Remove solid impurities such as iron oxide and dust contained in fuel oil to prevent fuel system blockage (especially fuel injectors). Reduce mechanical wear, ensure stable engine operation and improve reliability. Even if the diesel oil is cleaned before it is deposited and filtered before being added to the diesel fuel tank, during the refueling process, diesel fuel will still be polluted due to factors such as refueling tools, refueling environment, and unclean tank openings. Impurities deposited in the fuel system and suspended air in the air can also pollute diesel fuel, so the diesel filter on the car is essential, not to mention that the diesel fuel is not necessarily clean before it is added to the fuel tank.
kind:
Perkins diesel engine fuel filters in Britain are divided into three categories: diesel filters, gasoline filters and natural gas filters. The structure of the diesel filter is roughly the same as that of the oil filter, and there are two types: replaceable and spin-on. However, its working pressure and oil temperature resistance requirements are much lower than those of oil filters, while its filtering efficiency requirements are much higher than those of oil filters. The filter element of the diesel filter mostly uses filter paper, and some also use felt or polymer materials. In addition to filtering mechanical impurities in diesel, diesel filters also have an important function of filtering water. In order to achieve higher separation efficiency, two-stage filtration is currently used. One is oil-water separator and the other is diesel. Fine filter. The presence of water is extremely harmful to the fuel supply system of diesel engines. Corrosion, wear, and seizure can even worsen the combustion process of diesel. The water removal method of the diesel filter system is mainly sedimentation in the mechanical fuel system. In the era of emissions above State Three, diesel engines mostly use high-pressure common rail fuel systems, and water removal methods mostly use filter paper. BOSCH ),曼胡( Mann-Hummel ),帕克( Parker ),国内品牌有达菲特( DIFITE )。 At present, most of the water separators that meet the requirements of the national three or more emission engines are produced by foreign enterprises, such as BOSCH , Mann-Hummel , Parker , and domestic brands such as DIFITE . Gasoline filters are divided into carburetor type and electric injection type. Gasoline engines using carburetor are located on the inlet side of the fuel pump, and the working pressure is small. Generally, nylon housings are used. The gasoline filter is located on the outlet side of the fuel pump and has a higher working pressure, usually with a metal casing. The filter element of the gasoline filter mostly uses filter paper, and some also use nylon cloth and polymer materials.
  

working principle:
The Perkins diesel engine fuel filter is connected in series between the natural oil pump and the inlet of the throttle body. The role of the fuel filter is to remove solid impurities such as iron oxide and dust contained in the fuel to prevent the fuel system from blocking (especially the fuel injection nozzle). Reduce mechanical wear, ensure stable engine operation and improve reliability. The structure of the fuel burner is composed of an aluminum shell and a stainless steel bracket, and a high-efficiency filter paper is mounted on the bracket. The filter paper is daisy-shaped to increase the circulation area. EFI filters are not compatible with carburetor filters. 200—300KPA 的燃油压力,因此该滤清器耐压强度一般要求达到 500KPA 以上,而化油滤清器则没有必要达到如此高的压力。 Because the EFI filter often withstands 200-300KPA fuel pressure, the pressure resistance of the filter is generally required to be above 500KPA , while the carburetor filter does not need to reach such a high pressure.
How does a diesel filter filter out impurities
The structure of the diesel filter is roughly the same as that of the oil filter, and there are two types: replaceable and spin-on. However, its working pressure and oil temperature resistance requirements are much lower than those of oil filters, while its filtering efficiency requirements are much higher than those of oil filters. The filter element of the diesel filter mostly uses filter paper, and some also use felt or polymer materials. In addition to filtering mechanical impurities in diesel, diesel filters also have an important function of filtering water. The presence of water is extremely harmful to the fuel supply system of diesel engines. Corrosion, wear, damage to the piston rings of the cylinder will even cause the phenomenon of cylinder pulling, which can worsen the combustion process of diesel. [2] The diesel filtration system uses the fluid flow control technology to separate the water according to the difference in liquid density to achieve the effect of filtering water [2] .

At present, many foreign standards are adopted.    [3]
Impact of Poor Quality Filters on Perkins Diesel Engines
   使用低价格的滤纸制作滤芯,因其滤纸孔径大、均匀性差、过滤效率低,不能将对发动机有害的杂质进行有效滤除,造成发动机早期磨损。 1. Use low-priced filter paper to make the filter element. Due to its large pore size, poor uniformity, and low filtration efficiency, it cannot effectively filter harmful impurities to the engine, causing early engine wear.   

使用低质胶粘剂,而且用量极少,既不耐油,又不能牢固粘接,造成滤芯粘接处短路;或滤芯接缝处使用订书钉连接,无法密封而短路,使大量有害杂质进入发动机,消减发动机寿命。 2. Use of low-quality adhesives with very little amount, which is neither oil-resistant nor firmly adhered, which causes a short circuit at the bonding element of the filter element; or staples are used at the joints of the filter element, which cannot be sealed and short-circuited, causing a large number of harmful impurities to enter Engine, reducing engine life.   

以普通橡胶件替代耐油橡胶件,在使用过程中或因内部密封件密封失效形成滤清器内部短路致使发动机早期磨损、寿命消减或因外部密封件膨胀变形,造成机油滤清器外密封圈挤出,短时间内大量泄油,使发动机烧瓦、抱轴,遭受严重损害。 3. Replace the oil-resistant rubber parts with ordinary rubber parts. During the use process or due to the internal seal seal failure, the internal short-circuit of the filter may cause early wear of the engine, reduce the life span, or cause the external seal to expand and deform, causing the external seal of the oil filter. Extrusion of the ring, a large amount of oil leakage in a short period of time, causing the engine to burn the bushes, hold the shaft, and suffer serious damage.   

空滤器外壳部件焊接处以点焊替代缝焊,无法保证密封性,形成短路。 4. Spot welding is used instead of seam welding at the welded parts of the air filter housing, which cannot guarantee the tightness and form a short circuit.   

机油滤清器中心管材料以薄代厚,强度不够,在使用过程中因中心管吸瘪,滤芯破损堵塞油路,致使发动机润滑不足;或咬口处可靠性差,使用过程中咬口处拉开,致使机油在短时间内大量泄漏,因而造成烧瓦,抱轴。 5. The material of the central tube of the oil filter is thin and thick, and the strength is not enough. During use, the central tube sucks, the filter element is damaged and the oil path is blocked, resulting in insufficient engine lubrication; or the reliability at the bite is poor, and the bite is pulled during use On, causing a large amount of oil to leak in a short period of time, resulting in bush burning and shaft entrapment.   

滤芯端盖、中心管、外壳等金属部件,不进行防锈处理,致使金属锈蚀产生杂质,使滤清器变成了污染源。 6. Metal parts such as filter end caps, central tubes, and housings are not treated for rust prevention, which will cause metal rust to produce impurities and make the filter a source of pollution. What's more, replacing cement with cement is more harmful. Therefore, the cost of inferior filters is high, and users are advised to be cautious when replacing filters. It is best to choose original accessories to avoid unnecessary economic losses.
