Filter PL420 can't replace filters PL421

Filter PL420 can't replace filters PL421

In the past, the PL420 was used as the first primary filter for the fuel tank girders. There is no pressure. The common rail is pressurized, and the PL420 is under negative pressure. Before the appearance of the electronic pressure pump, the transparent cup is very safe, there is no pressure damage to the transparent cup, but with the advent of the electronic pressure pump, the engine's two coarse filters change from negative pressure to 4 positive pressures or even greater pressure. The old-fashioned PL420 transparent cup has the risk of oil leakage. Some OEMs changed the PL420 on the engine to the PL421 without a cup. However, some OEMs did not consider this problem. They still loaded the PL420. (There are now Delong) there are design risks. It is recommended to use the filter PL421 for models equipped with an electronic pump. Filters PL420 and PL421, we can provide, if you need, please feel free to contact us.

  • What are the effects of fuel filter replacement and non-replacement?

    What are the effects of fuel filter replacement and non-replacement?

    2019-05-31

    What are the effects of fuel filter replacement and non-replacement? Gasoline filtration is one of the common filter products, the main function is to remove impurities from gasoline. If the fuel filter is too dirty or blocked, the main performance is: when the fuel is added, the power is slower, or it can't get up, the car is difficult to start, sometimes it takes 2-5 times to catch the fire. Most engines are equipped with disposable, non-removable paper filter fuel filters. The replacement cycle is generally 10,000 kilometers. If you add less gasoline, it is not a problem to replace one with 15000-20000 kilometers. The filter has an inlet and outlet arrow mark, and should not be reversed when replacing. The fuel filter is to filter the impurities in the gasoline you usually add. It takes a long time. Your fuel filter is full of dirt, dirt and dregs. Therefore, it is recommended to change the number of kilometers. If you don't change it, or delay the change, it will definitely affect the performance of your car; for example, the oil road is not smooth, the car is not motivated, the time is long, the filter performance of the steam filter is greatly reduced, and finally the engine is damaged chronically, and even the engine is overhauled. If you don't change it, it will definitely bring a lot of damage to the car.

  • Cleaning, repair and replacement of dust collector bags

    Cleaning, repair and replacement of dust collector bags

    2019-05-18

    In the dust collector, the cloth bag is an important part, which mainly plays the role of filtering and collecting dust and debris to achieve purification. The cleaning, maintenance and replacement of the bag of the dust collector are as follows. 1. Cleaning of the bag: Cleaning: Select the appropriate washing materials, after strict ratio, and the cleaning strength should be moderate, the strength is too small, the cleaning is not thorough, and the lightness will cause damage to the bag.   Repair: If the bag is worn or corroded, it needs to be repaired to ensure that the bag can be used normally. However, if the situation is serious, professionals who require air handling equipment recommend replacing the bag.   Cleaning: By vibrating, the large dust particles in the bag are removed to maintain the filtration performance.   Drug soaking: It is the use of some chemical agents to remove oil stains or dirt that cannot be washed with water in order to increase the breathability of the bag.   Drying: Dry the bag with hot air at a temperature of 110 degrees Celsius. After the bag is dried, it must be guaranteed not to deform and retract.   Quality inspection packaging: After the cloth bag has been cleaned, it must undergo strict quality inspection. After the test is qualified, it can be packaged and affixed with a certificate. 2. Maintenance of the bag If the bag is damaged, stop working immediately and repair it. If it is just a small hole, it can be bonded using a silicone rubber compound at the breakage. When selecting a binder, be aware that it should be compatible with the temperature, chemical properties, and process of the bag, otherwise problems may occur. 3. Bag replacement If the bag is damaged seriously, or if a lot of tiny dust accumulates inside it, the cleaning effect is not ideal, and it has affected the use of the bag, it must be replaced. It is not necessary to stop the dust collector when replacing. Just turn off the cleaning controller and open the manhole door to replace it. After installing a new bag, clean it around.

  • Three elements that directly affect the service life of hydraulic oil filters

    Three elements that directly affect the service life of hydraulic oil filters

    2019-04-30

    The three factors that directly affect the service life of the hydraulic oil filter, the service life of the filter element in the hydraulic system is an important problem of the actual hydraulic system, especially in the case of high pollution conditions, the failure of the filter element and the resulting hydraulic system The fault is particularly prominent. There are three main factors that affect the life of a hydraulic filter: First, hydraulic oil filter filtration performance Filtration Accuracy: Filtration accuracy refers to the ability of the filter material to filter out particulate contaminants of different sizes. It is generally considered that the filtration precision is high and the life of the filter element is short. Second, the amount of pollution The amount of pollutants refers to the weight of particles contaminated by the filter material per unit area when the pressure drop of the filter material reaches a specified amount during the test. The filter element hole is easily retained by the accumulation of particulate contaminants through the channel, so that the pressure difference is increased, and when the pressure difference reaches the specified maximum limit value, the service life is terminated. The most direct parameter of the end of the filter life is that the pressure difference between the upstream and the downstream of the filter element reaches the pressure at which the bypass valve is opened. At this time, the dirt holding capacity of the filter element also reaches the maximum value. If the filter element is designed and manufactured, consider increasing the filter element. The ability to foul, that is, to improve the life of the filter. 1, wave height, wave number and filter area Under the premise that the outer dimensions of the filter element have been determined! Change the wave height, wave number and other process parameters to increase the effective filter area ofthe filter material as much as possible, which can reduce the flux of the unit filter surface and increase the dirt absorption of the whole filter element, and improve the filter life. By increasing the filter area ofthe filter element, the life of the filter element increases more often. If the wave number increases too much, the crowded folding wave will reduce the flow space of the hydraulic oil between the wave and the wave, so that the pressure difference of the filter element increases! The time difference of the differential pressure alarm is short and the life is reduced. It is generally preferred to keep the wave spacing between 1.5 and 2.5 mm. 2, the strength of the support network It is very important that the wire mesh of the inner and outer layers in the filter element structure has a certain strength. The wire mesh maintains the pleat shape to prevent bending and supports the filter material to prevent fatigue failure. Third, the pollution status of the hydraulic fluid during the use of the filter element After the filter element is ma...
