Weichai 612600081334 Fuel filter

Detailed product information

Type and function: Weichai fuel filters mainly include gross diesel fuel cleaning filters and thin -fuel fine filters. The coarse cleaning filter is used for the initial filtration of large particles of impurities and water in diesel fuel, reducing the load on the thin cleaning filter; The thin cleaning filter additionally filters small impurities, providing the engine with cleaner fuel and protecting the precision components, such as the injection system.

Material and structure: A filtering element made of microporous paper treated with phenol resin and made in the form of a folded cylinder is usually used. It has such advantages as good throughput, high filtering efficiency, simple structure, low cost and ease of maintenance. The outer shell is usually made of metal or high -strength plastic and can withstand a certain fuel pressure.

The main parameters: various types of fuel filters are characterized by accuracy of filtering, throughput, pressure resistance, etc. For example, the accuracy of filtering some filters can reach 5 microns, which allows you to effectively filter the impurities harmful to the engine; The consumption corresponds to the fuel need of the engine in various working conditions and provides a stable fuel supply; The pressure resistance, as a rule, is in a certain range for adaptation to the working pressure of the fuel system.

Installation

Replacing the node of the filter of rough cleaning

Disassembly: first disconnect the water -containing fuel fitting, then using the filter key, remove the fuel filter (rude cleaning filter), make sure that the sealing ring is not stuck in the filter saddle, and if necessary, remove the sealing ring using a tool for removing the sealing ring.

Installation: apply a thin layer of pure motor oil to the surface of the gasket and the average seal of the new filter, install it on the filter saddle, turn the filter until the gasket touches the surface of the filter saddle, when the gasket touches the surface of the filter saddle, tighten the filter to 3/4 turnover and, finally, connect the fuel water connector.

Replacing the filter node of thin cleaning

Disassembly: disconnect the negative battery cable and remove the fuel filter (thin cleaning filter) using the filter key, making sure that the seal was not stuck in the filter saddle.

Installation: fill a new filter with clean fuel, apply a thin layer of pure motor oil to the surface of the filter and medium sealing, install the fuel filter on the filter saddle, turn the filter to the contact of the filter saddle, and when the gasket comes in touch with the surface of the filter saddle, tighten the filter At 3/4 turnover.

Common malfunctions

Flowing: after prolonged use of impurities and moisture in the fuel, they gradually accumulate inside the filter, causing clogging, which leads to problems such as a difficult to launch the engine, reduction of power, unstable idle work and increased fuel consumption.

Oil leak: aging or damage to the filter seal, as well as cracks in the external case, can lead to fuel leakage. This will not only lead to the overspending of fuel, but can also create a threat to security, as well as cause a fire when exposed to open fire.

Damaged filter paper: prolonged use, poor fuel quality or external exposure can lead to damage to filter paper and loss of its filter ability, which will allow pollution to directly enter the engine and accelerate the wear of the components.

A malfunction of the bypass valve: the bypass valve must automatically open when the filter is clogged to ensure a continuous supply of fuel. However, if the bypass valve has an abnormal opening pressure or damaged, it can open when this is not necessary, which will allow non -den that the engine will get into the engine, or may not open when it is necessary, which will lead to insufficient fuel supply.

The cycle of replacement of Weichai diesel filter is affected by many factors. Below is a replacement cycle under normal circumstances:

By the time of execution

The first replacement: in the weichai diesel generator installations, a diesel filter must be replaced after the first 50 hours of operation.

Subsequent replacement: usually replaced every 400 hours of work. However, if diesel fuel of low quality or harsh working conditions is used, for example, work in a dusty or humid environment, the replacement cycle should be reduced accordingly, and, possibly, the replacement will have to be carried out every 200-300 hours.

By mileage

Normal operating conditions: with normal operation of the vehicle and refueling with ordinary diesel fuel from conventional gas stations, the Weichai diesel filter is usually replaced every 10,000–20,000 kilometers.

Severe operating conditions: if the vehicle is often operated in conditions of poor roads and high dusting, or if diesel fuel of medium -sized quality is used, it is recommended to replace fuel every 5000-10,000 kilometers.

To extend the service life of the Weichai diesel filter, you can start with the proper use of fuel, standardize daily services, optimize the operating conditions of the vehicle, etc. Below is introductory information for you:

Use high -quality fuel: high -quality diesel fuel contains less impurities and water, which can reduce clogging and wear of filters. Choose a dressing at a conventional gas station to avoid the use of poor -quality diesel fuel. For example, poor -quality diesel fuel may contain more solid particles, sulfur and other impurities that can quickly clog the filter element and reduce its service life.

Pour water regularly: for diesel filters with oil separators, separated water should be regularly drained. As a rule, the drain valve should be opened for draining water through each specific mileage (for example, 500-1000 kilometers) or through each specific period of time (for example, one week). Do not allow excessive accumulation of water in the filter, as this can affect the effectiveness of filtration, as well as lead to getting wet and damage to the filter element.

Replace the filter element in a timely manner: regularly replace the filter element in accordance with the operating manual for the car or the operating instructions for the filter. Even if the vehicle is in good working condition, you can not ignore the filter replacement cycle. It is usually recommended to replace the filter element through each specific mileage (for example, 10,000–20,000 kilometers) or at certain intervals (for example, 6-12 months). A specific cycle can be determined on the basis of actual use and operating manual.

Strengthen daily checks: regularly check the appearance of the filter for oil leaks, damage, etc. If you find cracks on the filter housing or signs of aging or damage to the sealing ring, you should replace the filter or related parts in a timely manner. At the same time, pay attention to the working condition of the filter, for example, whether the engine is difficult, whether the power is reduced, etc. If there are any deviations, perhaps the problem in the filter, which must be checked and eliminated in a timely manner.

Install the filter correctly: when replacing the filter, make sure that it is installed correctly. Before installing, the filter saddle and connecting pipes should be thoroughly to prevent pollution entering the filter. During the installation, tighten the filter with the indicated puffing moment to prevent oil leakage or a weakening of the filter due to improper installation. In addition, the filter sealing ring should be installed in place to ensure good tightness.

Optimize the operating conditions of the vehicle: try to avoid long -term operation of the vehicle in difficult conditions, for example, on dusty or dirty roads. When driving in such conditions, dust and impurities from the air can easily enter the fuel system, increasing the load on the filter. If driving in adverse conditions is inevitable, the cycle of checking and replacing filters should be reduced accordingly.

Use fuel additives: adding the corresponding number of high -quality fuel additives to diesel fuel can improve the operational characteristics of fuel, reduce the formation of impurities and help protect the filter. But be careful, choose fuel additives of reliable quality and add them in accordance with the prescribed dosage.
