Weichai 612630080373 Water Cup Assembly Original

Function

The Weichai fuel filter's primary water cup is a key component of the fuel filtration system, primarily responsible for separating water and large particles from the fuel. Before the fuel reaches sensitive engine components, it passes through the primary filter cup. The water cup effectively captures water droplets in the fuel, preventing water from entering the engine, and preventing engine rust, increased wear, and incomplete combustion due to the presence of water. It is also capable of filtering larger-diameter impurities such as dust, metal debris, and other particles, ensuring that the fuel entering the engine meets purity standards, ensuring stable and efficient engine operation and extending its service life.

Structural design

A water cup typically consists of a transparent body, base, filter element, water level sensor, and other components. The transparent body of the cup allows operators to visually observe the accumulation of water and contaminants within, allowing for timely maintenance. The base connects the entire coarse filter to the fuel line and is equipped with oil inlet and outlet ports to ensure smooth fuel flow. The filter element is the main filter element, typically constructed from multiple layers of filter media, such as filter paper, fiber, and other materials, and manufactured using a special process that effectively traps contaminants of varying particle sizes. A water level sensor is installed in a suitable location on the cup body. When the water in the cup reaches a certain level, it triggers an alarm to remind the user to drain the water promptly.

Material properties

The cup body is made of high-strength, fuel-corrosion-resistant structural plastic, which not only withstands a certain pressure, but is also resistant to chemicals contained in the fuel, which ensures long-term and stable operation in difficult operating conditions. The filter element is made of high-quality filter paper or high-performance fiber material, which has high filtration precision and dirt holding capacity, as well as good air permeability, which ensures fuel filtration efficiency without affecting its normal circulation. The base is usually made of metal, such as aluminum alloy or high-strength steel, and is precision machined to seal tightly with the cup body and fuel line, providing a good seal to prevent fuel leakage.

Applicable models

The Weichai fuel coarse filter water cup is designed for installation on various models equipped with Weichai engines, including heavy trucks, construction equipment (such as loaders, excavators, cranes, etc.), and some agricultural machinery. Although engine models vary, the fuel coarse filter can generally meet the fuel filtration needs of the corresponding engine. Its standardized design and interface configuration make it easy to install and replace.

Product Specifications

Weichai fuel pre-filters offer a variety of specifications to suit different engine filtration requirements and fuel flow rates. Typical capacity specifications range from 1 to 5 liters to meet the fuel purification needs of vehicles under various operating conditions. Filtration accuracy typically ranges from 10 to 50 microns, effectively filtering common impurities and moisture. There are also multiple connection interface size and thread specification standards to accommodate various fuel line systems.

To choose the right Weichai fuel pre-filter bowl for your vehicle, you can consider the following aspects:

Confirm your vehicle's engine model: Different Weichai engine models have different requirements for fuel consumption, pressure, and filtration accuracy. For example, high-power engines installed in heavy-duty trucks have high fuel consumption and require large, high-capacity primary filters, while engines used in small construction equipment have relatively low primary filter performance requirements. To select the appropriate primary filter cup, you can check your vehicle's owner's manual and the engine nameplate, which clearly indicate the engine model.

Pay attention to filtration accuracy: impurities in fuel vary in size, and the most common impurities include dust, metal debris, colloids, and so on. Generally, a coarse filter with a filtration accuracy of 10–50 microns can meet the needs of most vehicles. If the vehicle is frequently operated in dusty environments with poor road conditions, it is recommended to choose a water filter with a higher filtration accuracy, such as 10–20 microns, which is better able to capture small impurities and protect the engine's fuel system.

Consider the water tank capacity: Choose a water tank of appropriate capacity based on the vehicle's fuel consumption and operating time. Vehicles that operate continuously for long periods, such as long-haul trucks, should choose a coarse filter with a larger capacity to reduce the frequency of draining and maintenance; while vehicles with shorter operating times and relatively lower fuel consumption may benefit from a smaller filter. Typical water glasses hold between 1 and 5 liters.

Check the interface specifications: The fuel filter cup must be connected to the vehicle's fuel line, and the interface specifications must match. The interface size, thread specifications, etc. must match the original vehicle's. Otherwise, installation difficulties, poor sealing, and even fuel leaks may occur. Before purchasing, carefully measure the original vehicle's fuel line interface size or refer to the relevant specifications in the vehicle's service manual.

Choose regular channels and branded products: The quality of coarse filter cups varies across the market. To ensure product quality and performance, it is recommended to purchase from official, authorized Weichai dealers or regular auto parts stores. Products supplied through official channels have a greater quality guarantee and after-sales service, effectively avoiding counterfeit and low-quality products.

The Weichai fuel pre-filter water cup is suitable for various models equipped with Weichai engines, the most common of which are:

Heavy-duty trucks: Like the Shaanxi Automobile Delong series, these have high power requirements and high engine operating temperatures. The Weichai fuel water cup effectively filters fuel, ensuring stable engine operation and reducing failures caused by impurities in the fuel. In some Auman models, when transporting long distances under difficult road conditions and using fuel of varying quality, the water cup can trap impurities and moisture, maintaining engine output and improving vehicle reliability.

Construction equipment: Loaders, excavators, and other equipment operate in harsh conditions, and their fuel is easily contaminated. For example, some construction equipment from brands such as XCMG and Liugong, when equipped with Weichai engines, has a corresponding coarse water filter that continuously supplies the engine with clean fuel even in dusty and vibrating conditions, thereby extending engine life and ensuring proper equipment operation.

Buses: Some buses from brands like Yutong and King Long use Weichai engines for urban public transportation and intercity passenger travel. A matching fuel pre-filter with a water cup filters out harmful particles and water from the fuel, maintaining good engine performance, reducing exhaust emissions, and improving ride comfort.

Agricultural Machinery: Agricultural machinery, such as tractors and combines, place high demands on fuel flexibility when operating in the field. Some agricultural machinery from brands such as Lovol and Dongfanghong uses Weichai engines. A suitable coarse water filter can adapt to agricultural fuels of varying quality, ensuring stable operation during busy agricultural seasons such as spring plowing and autumn harvesting.

In short, if your car is equipped with a Weichai engine, you can refer to the car owner's manual or consult with the official Weichai after-sales service representative to accurately determine the appropriate fuel pre-filter water cup model and ensure the stable operation of the car's fuel system.
